Bariatric and metabolic surgery
In this authoritative lecture, Dr. Michel Vix highlighted the indications related to metabolic and morbid obesity surgery. He presented key anatomical landmarks and operating room (OR) set-up depending on every patient. He briefly described the main principles of port placement and pneumoperitoneum, and demonstrated maneuvers, indications, and main key steps of morbid obesity procedures including LAGB, SBPD-DS, Scopinaro, RYGB, Mini Gastric Bypass, and Sleeve Gastrectomy, along with their technical aspects, mortality, morbidity, effectiveness, and results using different studies and meta-analyses. He also demonstrated the main principles and key steps of new trends and approaches in bariatric and metabolic surgery with complications and technical therapeutic aspects.

Minimally invasive right superior parathyroidectomy (MIVAP) for symptomatic primary hyperparathyroidism
This video presents the case of a 62 year-old patient with primary hyperparathyroidism characterized by a PTH which is inconsistent with calcium levels. The diagnosis is confirmed by biological findings before searching for the adenoma inducing this hypersecretion. With the use of current precision imaging techniques, in most cases, the adenoma can be identified and managed surgically. In our team, we perform a 99m Tc-MIBI scintigraphy and a CT-scan allowing for a 3D reconstruction according to the IRCAD protocol. This 3D reconstruction shows the relationships between the adenoma, the inferior thyroid artery, the thyroid gland, and the esophagus, making it possible to perform a video-assisted approach using a scar inferior to 2cm.

PerOral Endoscopic Thyroidectomy (POET), a novel pioneering technique
Thyroid surgery has evolved towards minimally invasive approaches to reduce or prevent cervical scars, which are potential seats for keloidal scarring. Several approaches have been put forward: video-assisted surgery via a reduced cervical scar, transaxillary access with or without robotic assistance, transoral retromandibular approach, retroauricular approach in keeping with a lifting procedure.
In this video, we present the case of an original transoral vestibular approach. This access is exclusively subcutaneous. No cervical scar is necessary. This technique allows for a unilateral or bilateral approach in excellent visualization conditions. Dissection is performed from cranially to caudally with the rapid identification of the inferior laryngeal nerve.

Video-assisted exploration of the four parathyroid lobes for primary hyperparathyroidism
Background:
The presence of a single parathyroid adenoma accurately located using preoperative imaging is the best indication for minimally invasive surgery when dealing with primary hyperparathyroidism. It is certainly possible to search for several glands that may be suspicious of adenoma, but an extensive experience in video-assisted cervical surgery is required to find the anatomical structures allowing to explore the four parathyroid locations.
Patient and methods:
A 75-year-old obese woman is diagnosed with hypercalcemia, hypophosphoremia, and a high level of PTH during a work-up for joint pain.

Preoperative imaging includes a 3D-reconstructed cervico-mediastinal CT-scan —a computer program developed at the IRCAD-Strasbourg, named VrAnat™, Vr planning™, is used for that purpose. This 3D virtual reconstruction demonstrates three suspicious images respectively located at the right superior parathyroid territory, at the right latero-esophageal area, and at the left inferior parathyroid territory. A video-assisted cervical exploration, guided by this reconstruction, is decided upon. The objective is to find the three suspicious images and to explore the four parathyroid glands.

A 3cm median incision is carried out 2cm above the sternal notch. The right thyrotracheal groove is reached through a dissection performed laterally to the strap muscles and medially to the omohyoid muscle. A complete dissection of the lateral aspect of the thyroid lobe is obtained using blunt dissection and small instruments under endoscopic vision, which is provided by a 30-degree, 5mm scope (Storz, Tüttlingen, Germany). The recurrent laryngeal nerve is identified.

Dissection is now carried on above the inferior thyroid artery. It allows to rapidly identify a superior parathyroid adenoma, which will be resected. It exactly matches with one of the suspicious images.

Dissection is pursued anterior to the intersection between the artery and the nerve so as to find the right inferior parathyroid, which is healthy, underneath the capsule. The latero-esophageal image is now searched for. It is nothing but an anthracosic lymph node.

The left side is approached by dissecting the left jugulocarotid gutter. The left recurrent nerve is identified. The left inferior parathyroid is identified and looks healthy. The suspected image is nothing else but a nodule of the apex of the thyrothymic ligament. The left superior parathyroid, which is healthy, can be finally identified in a strictly orthotopic position, although partially hidden behind a Zuckerkandl’s nodule.

Conclusion:
This cervical exploration has led to the dissection and visualization of the four parathyroid lobes in compliance with classical parathyroid surgery principles.

The VERSA LIFTER BAND™: a new option for liver retraction in laparoscopic Roux-en-Y gastric bypass for morbid obesity
During laparoscopic bariatric procedures in morbidly obese patients, the surgeon's operative view is often obscured by the hypertrophic adipose left lobe of the liver.
To provide adequate operative views and working space, an appropriate retraction of the left liver lobe is required.
The use of a conventional liver retractor mandates an additional subxiphoid wound, resulting in patient discomfort for pain and scar formation, with the additional risk of iatrogenic liver injury during retraction maneuvers.
To overcome these limitations, we present the use of a simple, rapid, and safe technique for liver retraction using the VERSA LIFTER™ Band disposable liver suspension system or retractor.

Laparoscopic Roux-en-Y gastric bypass: live demonstration and technical details
Roux-en-Y gastric bypass (RYGB) has become a common procedure for the management of morbid obesity. However, learning to perform such a procedure may be difficult as it is made up of very technical operative steps in complex cases of overweight patients with a great amount of adipose tissue. In order to prevent complications, an operative strategy should be adopted, allowing for an easy and rapid acquisition of the technique. Each step is perfectly mastered and outlined.
This video demonstrates a laparoscopic Roux-en-Y gastric bypass performed live, showing all the preoperative and operative patient settings. The surgical technique is thoroughly explained.

Laparoscopic Roux-en-Y gastric bypass after gastric band removal
This video demonstrates the case of a 50-year-old woman with morbid obesity (BMI of 39). She had a gastric banding placed 7 years before, which became ineffective 3 years after the primary surgery, resulting in band removal 2 years ago.
A secondary bariatric surgery was scheduled, with the decision to perform a laparoscopic Roux-en-Y gastric bypass. This video shows the surgical technique, with special emphasis on dissection of the cardia and lesser curvature, where the anatomy is altered as a result of the previous band. An interesting technical point occurs during the creation of the jejunojejunostomy, where a perforation of the biliary loop is accidentally made during the EndoGIATM linear stapler introduction.

Robot-assisted Roux-en-Y gastric bypass after band removal
Patients ask for a new weight loss surgical procedure after gastric band removal due to a lack of efficiency or to complications. Although gastric banding is a reversible procedure, perigastric adhesions located mostly in the upper part of the stomach can make new approaches to this area difficult.
We report the case of a woman who benefited from a gastric banding in 2006. This gastric band was removed in 2010. The patient developed a left subphrenic abscess, which was drained under CT-scan control postoperatively.
Two years after this procedure, the patient wishes to benefit from a new weight loss surgical procedure as she gained 10Kg since her gastric band removal. She has a BMI of 40 and presents with respiratory and rheumatological co-morbidities.
The preoperative work-up was uneventful, and this is particularly true for the esogastroduodenal contrast exam and the gastroscopy.
During the procedure, multiple omental parietal adhesions were found, as well as tight adhesions between the liver, the stomach, and the left crus.
Dissecting the stomach using a conventional approach was made difficult by the presence of these adhesions, and we had to perform an upper pole gastrectomy of the greater curvature in order to clearly identify the gastroesophageal junction’s anatomy. A complete dissection of the left subcardial area is necessary in order to prevent the formation of an excessively large gastric pouch, which could lead to a regain in weight.
This video covers the whole procedure in detail and highlights dissection challenges, which can occur in patients who had their gastric band removed.
The postoperative outcome was uneventful in this woman, with a significant weight loss at one year.

Robot-assisted gastric band removal
Adjustable gastric banding (AGB) is one of the surgical treatment modalities for morbid obesity. Over the years, popularity for this treatment increased. It has been by far the most performed bariatric procedure for years in Europe and in the United States. Many gastric band removals are linked to complications and weight loss failure, indicating a new bariatric procedure for some of the patients. Complications after AGB are not uncommon and consist mainly of gastroesophageal reflux disease, pouch dilatation, slippage of the band, and intragastric migration. The failure of the gastric band is multifactorial. Gastric band removal does not preclude a new bariatric procedure (the most common procedure performed in our department is Roux en-Y gastric bypass), which is feasible in the same operative time but the 2-step approach is suitable. The new bariatric procedure offers adequate surgical outcomes and satisfactory results in terms of weight loss.

Perforated gastric pouch ulcer 4 years after gastric bypass surgery: laparoscopic diagnosis and treatment
The frequency of marginal ulcers is reported to range between 0.6% and 16% after laparoscopic Roux-en-Y gastric bypass. Etiologies include gastrogastric fistula, excessively large gastric pouch containing antral mucosa, H pylori infection, non-steroidal anti-inflammatory drugs use, and smoking [1, 2]. We present a rare case of a gastric pouch ulcer perforation occurring 4 years after a laparoscopic gastric bypass.

Laparoscopic Roux-en-Y gastric bypass after gastric band removal with severe small bowel adhesions
After gastric band removal, a laparoscopic Roux-en-Y gastric bypass is rendered more difficult by the existence of adhesions between the liver, the superior part of the stomach, and potentially the spleen. This video describes how to handle difficulties in dissecting the superior part of the stomach. Dissection of the cardia and left crus are required to allow for an appropriate calibration of the gastric pouch. The difficulty is subsequently increased in this patient as there are dense small bowel adhesions related to a previous history of gynecologic peritonitis. The intervention has been entirely performed laparoscopically. Small bowel adhesions have been taken down in order to obtain a sufficient free length (approximately 2 meters) and perform a jejunojejunostomy in adequate conditions.

Onset of internal hernia after Roux-en-Y gastric bypass: laparoscopic management
Laparoscopic Roux-en-Y gastric bypass (LRYGB) represents the gold standard of treatment for morbidly obese patients. While the laparoscopic approach offers many advantages in terms of fewer wound complications, decreased length of hospital stay, and decreased postoperative pain, certain complications of this operation present difficult clinical problems. The most challenging complication to determine is internal hernia through one of the mesenteric defects.

Internal hernias occur more frequently in LRYGB than in the open procedure. This is a significant clinical problem since internal hernia is the most common cause of small bowel obstruction (SBO) after LRYGB, which can result in ischemia or infarction and often requires a reoperation.

The incidence of SBO after LGBP is reported to be between 1.8 and 9.7%. The most common site of internal hernia after LGBP is at Petersen’s space.
In this video, we present the laparoscopic management of a complete small bowel herniation at Petersen’s space.

Successful laparoscopic reversal of Roux-en-Y gastric bypass in a patient suffering from malnutrition authored by JY Park and YJ Kim (Soonchunhyang University Seoul Hospital, Seoul, South Korea)
The video entitled "Successful laparoscopic reversal of Roux-en-Y gastric bypass in a patient suffering from malnutrition", authored by JY Park and YJ Kim (Soonchunhyang University Seoul Hospital, Seoul, South Korea) is analyzed by Dr. Michel Vix, MD (Nouvel Hôpital Civil, Strasbourg, France), sharing in this way his own personal experience and highlighting the different surgical approaches available with tips and tricks.

Reply from Dr. Ji Yeon Park to the reviewer:
The South Korean surgeon in the current case, who originally was a gastric cancer surgeon, was extremely inexperienced in bariatric surgery at the time of the primary surgery in this patient. He applied “uncut” Roux-en-Y reconstruction for gastric cancer surgery to RYGB in this patient; it is a simple modification of Billroth II with Braun anastomosis with additional occlusion of the jejunogastric pathway with a non-bladed linear stapler. Consequently, sufficient distance between the gastrojejunostomy and the jejunojejunostomy was preserved in order to prevent bile reflux into the remnant stomach when staple-line recanalization occurs. However, intraoperative findings at reversal showed that the previously uncut staple line was found split apart, far from being recanalized. This consequently resulted in a long “true” blind loop at the distal end of the biliopancreatic limb. At reversal, we established a new jejunojejunal anastomosis between the distal end of the blind loop and the cut end of the proximal alimentary limb, and left the old jejunojejunostomy in situ. The operative procedure per se became much simpler by not dismantling the old jejunojejunostomy; as a result, the number of new anastomoses and the operating time could be reduced.

Laparoscopic central pancreatectomy for insulinoma
We report the case of a 43-year-old male patient who was diagnosed with insulinoma and had a robotic enucleation of an isthmic pancreatic tumor in November 2012. However, the patient presents with clinical recurrences of hypoglycemia 18 months later. Re-evaluation studies demonstrated a local recurrence. A laparoscopic central pancreatectomy was indicated. The procedure started with the opening of the lesser sac. The splenic vessels were dissected and controlled. A retropancreatic passage along the venous mesenterico-portal axis was performed. Ultrasonography was carried out to assess the pancreatic recurrence area. The pancreas isthmus was transected. A pancreaticogastric anastomosis was performed at the posterior aspect of the stomach. The resected specimen confirms the recurrence of an insulinoma, which has been entirely removed.

Laparoscopic and endoscopic treatment of a complicated candy cane syndrome after Roux-en-Y gastric bypass
A “Candy Cane” Roux syndrome represents an excessive length of non-functional Roux limb proximal to the gastrojejunostomy, which can cause abnormal upper gastrointestinal symptoms of postprandial epigastric discomfort that is relieved by vomiting. Symptoms of reflux, loss of satiety, and nausea are also common. The length of the blind loop is the essential factor to explain these symptoms, but the orientation of the gastrojejunal anastomosis is equally important to facilitate the emptying of the gastric pouch.
Scarce data can be found in the literature --a case report (1) and a case series (2) with a number of limitations. It is not possible to determine a critical excess length of Roux limb at which symptoms would become evident, nor were we able to determine whether all patients, or just a small minority, would develop symptoms, even with a seemingly excessive Roux limb.
Patients who underwent a gastric bypass technique with a gastrojejunal anastomosis using a circular stapler seem to be more likely to develop this anomaly. All 3 patients described by Cottam et al. (2) have their primary procedure performed by means of a circular stapler.
A long, non-functional Roux limb tip may cause persistent nausea, postprandial epigastric pain, and even a lack of satiety. Surgeons should attempt to minimize redundancy in the Roux limb during the primary procedure. Limiting the length and orientating the Roux limb to aid in gravity and drainage during the initial operation may prevent this syndrome.

Laparoscopic and endoscopic treatment of a complicated candy cane syndrome after Roux-en-Y gastric bypass
A “Candy Cane” Roux syndrome represents an excessive length of non-functional Roux limb proximal to the gastrojejunostomy, which can cause abnormal upper gastrointestinal symptoms of postprandial epigastric discomfort that is relieved by vomiting. Symptoms of reflux, loss of satiety, and nausea are also common. The length of the blind loop is the essential factor to explain these symptoms, but the orientation of the gastrojejunal anastomosis is equally important to facilitate the emptying of the gastric pouch.

Robot-assisted gastric band removal: any limitations?
Nowadays, indications for gastric band removal are well-standardized. In case of esophageal or gastric dilatation, migration or any injury related to the LAP-BAND® access port or tubing, the band and its access port should be removed. In rare specific cases, part of the LAP-BAND® system (either access port or band) may be preserved.
Before proceeding to the surgical band removal, a complete preoperative radiological and endoscopic work-up should be performed.
Here, we present the case of a 62-year-old woman who benefited from gastric band placement 10 years earlier. The band proved effective. However, for several weeks, she has been suffering from abdominal pain associated with vomiting and hematemesis.
After a work-up which included CT-scanning, water-soluble contrast swallow and gastroscopy, it was decided to remove the band.

Typical laparoscopic four-trocar transabdominal adrenalectomy for a 5cm right-sided pheochromocytoma
This is the case of a female patient presenting with a typical 5cm right-sided pheochromocytoma was operated on laparoscopically. Preoperative 3D MRI reconstruction allowed to precisely identify surgical landmarks. The procedure was carried out typically. Four ports were used, and dissection aimed to first mobilize the liver. Control of the main adrenal vein was achieved as the first operative step. Medial, superior, and inferior arteries were dissected and controlled successively. Total freeing of the gland was performed with no manipulation or effraction of the gland's capsule. The postoperative course was uneventful. Small-sized pheochromocytomas are excellent indications for a laparoscopic approach with early control of the vein.

Robot-assisted mini gastric bypass in a patient with a huge liver
This video demonstrates our mini gastric bypass technique using the da Vinci™ robotic surgical system. This intervention may be suggested in all morbidly obese patients without any major gastroesophageal reflux. One of the interests of this film lies in that the patient has a huge liver requiring delicate dissection and division of the superior gastric pouch. The biliary loop typically measures 200cm, and we systematically close Petersen’s defect in order to prevent internal hernias. The use of the surgical robot allows to perform an easier hand-assisted gastrojejunostomy. None of the preparatory maneuvers rely on the surgical robot as it is currently not equipped with mechanical staplers.

Occurrence of a rare complication during laparoscopic sleeve gastrectomy
Nowadays, sleeve gastrectomy is a common procedure frequently performed laparoscopically in the management of morbid obesity. This intervention as proven to be efficient in comparison to laparoscopic Roux-en-Y gastric bypass (LRYGB) regarding weight loss and revision of obesity-related co-morbidities such as diabetes mellitus and high blood pressure. Today, in France, selection of the surgical technique (e.g., sleeve gastrectomy, LRYGB) depends on the patient should preoperative work-up be strictly normal. If not, the surgeon will have to make a decision as to which technique should be used. Postoperative complications related to bariatric surgery are currently well-known (fistula, bleeding, abscess) and are managed in a multidisciplinary way by radiologists, endoscopists and surgeons. Here, we present the case of a rare perioperative complication related to the incidental stapling of the nasogastric tube during gastric division. This complication mainly highlights shortcomings in the interaction between the surgical team and anesthesiologists during placement and retrieval of calibration and nasogastric tubes. In the present case, this complication was immediately demonstrated and it was managed laparoscopically.

Robot-assisted revision of stenotic gastrojejunostomy after laparoscopic Roux-en-Y gastric bypass
This video presents the case of a 37-year-old woman who benefited from a laparoscopic Roux-en-Y gastric bypass with circular gastrojejunal anastomosis one year ago. An anastomotic stenosis rapidly occurred. It was managed conventionally by several endoscopic balloon dilatations without any stable results. It was found legitimate to offer the patient a revision of the gastrojejunostomy. Prior to performing the reintervention, a nasojejunal tube was placed in order to improve the patient’s enteral nutrition. Surgery consisted in the resection of the existing gastrojejunostomy and in the tailoring of a new manual anastomosis using the da Vinci™ robotic Surgical System. The postoperative outcome was uneventful. The patient no longer reports any dysphagia 3 months postoperatively.

Laparoscopic Roux-en-Y gastric bypass with linear gastrojejunostomy: occurrence of postsurgical complications
Roux-en-Y gastric bypass is a common procedure in bariatric surgery. It can be perfectly standardized in order to make it technically easier to perform and to reduce risks of postoperative complications. This video shows a conventional gastric bypass procedure with linear gastrojejunostomy. The intervention ran smoothly. Twenty-four hours postoperatively, the patient complained of abdominal pain. Serum chemistries demonstrated severe inflammatory signs. An emergency CT-scan demonstrated a gastrojejunal fistula. It was decided to perform an emergency laparoscopic reintervention. An anastomotic dehiscence was identified and sutured. The postoperative outcome was finally uneventful.

Image of the month: anterior abdominal mass after hysterectomy
This video demonstrates the case of a woman presenting with a mass appended to the anterior abdominal wall. In the patient’s surgical history, a hysterectomy performed a few years earlier can be noted. The operative report of that intervention is not available. Laparoscopy is therefore decided upon. The first impression is that of an ovarian lesion appended to the anterior abdominal wall. Consequently, an appendicular lesion must be ruled out. The appendix is therefore searched for and dissected. It remains distal from the mass and its pedicle. The presence of a tubular structure in the mass’s pedicle mandates the identification of the right ureter, which also remains distally. From then onwards, resection of the mass does not pose any particular problem. The pathological finding confirms the nature of the mass, namely a benign ovarian cystadenoma.

Video-assisted parathyroidectomy using augmented reality
The effectiveness of preoperative imaging to detect parathyroid adenomas allows for a targeted minimally invasive video-assisted approach. In our department, at the IRCAD, special software is used to virtually reconstruct the neck and its structures from mere CT-scan images of the cervicomediastinal region. This virtual reconstruction helps to precisely define the location of the parathyroid adenoma in relation to the superior part of the sternum, to the inferior thyroid artery and to the thyroid gland, hence guiding the surgeon in the proper identification of anatomical landmarks.
The reconstruction also helps to control the absence of "non-recurrent" recurrent nerves showing the presence of a right brachiocephalic arterial trunk.

Robotic-assisted mini gastric bypass
Amongst bariatric procedures, mini gastric bypass has been described by Rutledge in 2001 with the objective of simplifying the gastric bypass technique (1). Mini gastric bypass only requires one anastomosis instead of 2 and should reduce complications related to the anastomosis at the foot of the loop in a conventional gastric bypass procedure. A few specificities should be pointed out. The gastric pouch is longer and more narrow. The landmark used to start the gastric division corresponds to the area separating the body of the stomach from the antrum at the level of the angulus. The biliary limb is also much longer and should reach 2cm in order to avoid the undiluted biliary fluid effects on the anastomosis. In this intervention, it is crucial to closue Petersen’s defect between the mounted loop and the transverse mesocolon. According to Himpens, this procedure could well reduce the incidence of hypoglycemias that might occur after a gastric bypass. This video outlines the different steps of the intervention. The use of a surgical robot allows to very easily perform a manual gastrojejunostomy.

Gastric band removal for weight regain
Patients with a gastric band frequently request for its removal when it becomes inefficient in order to envisage another bariatric procedure. The intervention consists in the dissection of several adhesions between the liver and the stomach, the freeing of the gastric wrap, and the band removal. This procedure may be made uneasy because of the abundance and tightness of adhesions. In a few cases, our team has performed another procedure at the same time but usually we delay the second procedure in order to reduce complication risks, and more particularly anastomotic risks linked to this new intervention. The second interventions should be performed at least 2 months apart in order to allow for proper scarring of the gastric wall which harboured the band.

Gastric bypass after band removal: robotic-assisted gastrojejunostomy and linear-stapled jejunojejunostomy
Laparoscopic gastric bypass performed after gastric band removal requires the same surgical steps as a conventional gastric bypass. The presence of adhesions between the liver and the stomach makes the dissection of the superior gastric pouch more difficult. It is essential to correctly visualize the left crus during the dissection.
When the gastric pouch has been created, the other steps of the intervention remain conventional. Our team is currently evaluating the interest of using the Da Vinci™ surgical robot in morbid obesity surgery. As a result, we regularly perform a hand-assisted gastrojejunal anastomosis using the robot. The anastomosis is therefore easier to perform as the robot offers specific degrees of freedom. Consequently, the surgeon benefits from a more ergonomic position. In order to substantially increase surgical time, we opted for a conventional jejunojejunal anastomosis without the assistance of the surgical robot.

Primary hyperparathyroidism cure using 3D CT-scan reconstruction
Parathyroid surgery has largely benefited from advances in preoperative imaging modalities allowing to determine potential adenomas. Conventionally, ultrasonography and scintigraphy with 99mTc-sestamibi (MIBI) provide sufficient information to guide the surgical procedure. Specific software has been developed at the IRCAD to allow for the 3D reconstruction of the entire cervical structures. The handling of such reconstruction helps to perform a precise preoperative assessment. Arterial reconstruction allows to predict the existence of an arteria lusoria and of a non-recurrent recurrent nerve. In this case, the position of a potential adenoma in relation to the inferior thyroid artery allows to anticipate that it is not an adenoma but a thyroid nodule. A second potential target is visualized inferiorly. These two potential locations will be explored during the video-assisted surgical intervention.

Gastric bypass is considered to be the gold standard in morbid obesity surgery.
If technical principles are well-established, there are several alternatives to apply them. Consequently, gastrojejunostomy can be performed in three different fashions: manual, linear, and circular. Manual anastomosis can be performed with the help of the robotic Da Vinci™ Surgical System. This robot is particularly suited for manual anastomosis thanks to the instruments’ articulated extremities. Operative steps that do not benefit from robotics are performed by means of conventional laparoscopy, and especially gastric pouch division. This video also demonstrates the combined use of ultrasonic wireless scissors developed by Covidien (i.e., the Sonicision™ cordless ultrasonic dissection device).

Hand-sewn retrogastric retrocolic gastric bypass
Nowadays, the Roux-en-Y gastric bypass has become a gold standard in bariatric surgery. In this procedure, the stomach is divided into a small gastric pouch and a Y-shaped section of the intestine is then fashioned and joined to the gastric pouch. A jejunojejunal anastomosis allows for a restoration of the duodenal continuity. This video demonstrates several technical options for these two anastomoses. Dr. Higa has an outstanding experience in the field and has subsequently been able to ergonomically improve every operative step, which is being shown in detail in the video. Authoritative interaction of the expert with the operating room staff is ideal to promote clear and stepwise explanations throughout the procedure. Antecolic or retrocolic approaches, the necessity to look for a hiatal hernia as well as which type of gastrojejunal anastomosis is required are being discussed. This intervention allows for a true teaching lesson in the field of morbid obesity surgery.

Appendicular mucocele: laparoscopic management
Appendicular mucocele is a rare, yet typical tumor of the appendix. Its potentially malignant nature, the risk of pseudomyxoma peritonei (PMP) in case of rupture mandates a surgical resection without damage. In this case, diagnosis was suspected during colonoscopy performed because of right iliac fossa pain. The exam revealed an appendicular protrusion. CT-scan demonstrated the presence of an appendicular mucocele. A laparoscopic approach was decided upon. Parietal adhesions were identified. A primary vascular approach is then carried out. Once the ileocolic division has been achieved, a medial approach allows to complete the dissection within the wall keeping away from the lesion. Following the complete specimen resection, an ileocolic anastomosis is performed laparoscopically. At the end of the intervention, a small bowel exploration helps to identify a Meckel’s diverticulum that will be resected.

Laparoscopic simplified gastric bypass
Laparoscopic gastric bypass is currently the gold standard in bariatric surgery. This procedure is complex and yet, it can be perfectly standardized in order to shorten the learning curve. This video presents a well-standardized and easily reproducible technique. All operative steps have been systematized and unroll very naturally. Once the gastric pouch has been divided, the gastrojejunal anastomosis is performed by means of a linear stapler by calibrating a 3cm pouch. The jejunojejunal anastomosis is performed using a 45mm long linear stapler without any division of the alimentary loop. Consequently, it is easy to control the patency of the two anastomoses. Mesenteric defects are closed to avoid internal hernias. Reproducibility is the main advantage of this technique, which has been used by operators to train more than 700 surgeons in South America, Europe, and Asia.

Explorative laparoscopy: resection of small bowel for vascular tumor
The management of patients with small bowel bleeding remains a diagnostic and therapeutic challenge. In about 5% of cases, upper endoscopy and colonoscopy are nondiagnostic, and the small intestine is the site of bleeding,
This is the case of a 55-year-old patient admitted to the emergency department for a digestive hemorrhagic syndrome. The patient’s hemoglobin levels dropped to 6 grams per 100mL. The patient’s resuscitation allowed for the stabilization and restoration of blood volume.
Gastroscopy and colonoscopy did not demonstrate any etiology of bleeding. An emergency CT-scan found a suspected lesion at the level of the small bowel with contrast medium extravasation.
A video-endoscopic capsule was administered to the patient. It helped to identify the presence of a bleeding polypoid lesion on the middle portion of the jejunum. This video shows the laparoscopid resection of the lesion.

Explorative laparoscopy: resection of small bowel for vascular tumor
The management of patients with small bowel bleeding remains a diagnostic and therapeutic challenge. In about 5% of cases, upper endoscopy and colonoscopy are nondiagnostic, and the small intestine is the site of bleeding,

Laparoscopic exploration after Roux-en-Y gastric bypass following intestinal obstruction
This video demonstrates a laparoscopic exploration in a female patient who had undergone a gastric bypass in 2002. Her BMI was 58 at that time. Now it is 20. She had been operated on for an incisional hernia that occurred at the level of the former umbilical optical port site. She suffered from several episodes of proven mechanical bowel obstruction and benefited from medical treatment.
However, despite a thorough preoperative work-up, including gastroscopy, colonoscopy and repeat CT-scan studies performed over 6 months, the mechanical origin of the bowel obstruction was difficult to demonstrate. Since the patient had chronic, cramp-like abdominal pain, the exploration of the abdominal cavity using the former port entry sites is decided upon.

Perigastric band abscess: laparoscopic approach
Band infection after gastric banding is a relatively rare complication. In most cases, it manifests itself through abdominal pain associated with fever, and/or an abscess surrounding the access port. This is the case of a 37-year-old female patient in whom a gastric band was placed 5 years ago. The patient lost 60% of her excess weight; however, she complained that the gastric band was no longer as efficient. Imaging studies allowed to identify the existence of a 50mL supragastric pouch. A gastroscopy reveals nothing unusual.
Following this postoperative control, we decided to remove the patient’s gastric band as she was troubled by the superior gastric pouch.

Staple line failure during NOTES sleeve gastrectomy
In current surgical practice, the majority of the anastomoses is performed using a stapling device. Despite correct usage, staple line failure might still occur.
Concerning surgical stapling devices, the United States Food and Drug Administration (FDA) received reports of 22,804 malfunctions, 2,180 injuries, and 112 deaths from 1992 to July 1, 2001. These numbers included all types of linear and circular stapling devices as well as clip appliers. The majority of operations reported were gastrointestinal. Failure of stapling devices to function resulted in suture line separation or leak as the most common problem. When interpreting these data, it should be borne in mind that besides the fact that staplers are used very frequently, surgeons have to know the appropriate surgical techniques to inspect and verify staple line defects, and the techniques to employ if issues occur especially when performing complex surgery such as in this case of NOTES sleeve gastrectomy.
Thanks to the high skills of the surgeon, the procedure was completed using only one further port.

Transvaginal hybrid sleeve gastrectomy in a patient with a BMI of 40: live surgery during a NOTES course
Laparoscopic sleeve gastrectomy is a relatively new procedure, which is gaining popularity for the treatment of morbid obesity. In this live video demonstration from the March 2009 NOTES Advanced Course at IRCAD in Strasbourg, Dr. Michel Vix performs a hybrid natural orifice transluminal endoscopic sleeve gastrectomy using the vagina as the natural orifice and only two operative 5mm ports. It is a very interesting video demonstration showing that sleeve gastrectomy for the treatment of morbid obesity is feasible and safe in selected patients using the hybrid transvaginal mini-laparoscopic-assisted natural orifice surgery.

Gastric bypass: surgical treatment of morbid obesity
Morbid obesity is a major health concern in so many countries. It is associated with severe life-threatening co-morbidities. Unfortunately, many studies have proven that non-surgical approaches to lose weight are doomed to fail. There is good evidence that bariatric surgery is the most enduring and efficacious means of tackling morbid obesity with regards to long-term weight loss.

Roux-en-Y gastric bypass is today one of the gold standard surgeries. It is based on several mechanisms: restriction, malabsorption, and changes in gut hormones secretions.
In this chapter, all aspects of this bariatric procedure such as anatomical details, indications, contraindications, surgical setting and technical details are carefully presented.

Laparoscopic Roux-en-Y gastric bypass after vertical banded gastroplasty
Patients who have undergone bariatric surgery and present with upper abdominal symptoms pose a diagnostic and management challenge.
Laparoscopic vertical banded gastroplasty (VBG) is associated with high revisional rates. In the case of failed VBG, repeat VBG seems to be a poor option and conversion to gastric bypass yields better results.
This is the case of a 35-year-old female patient who underwent a vertical banded gastroplasty by laparotomy 8 years ago and presents with dysphagia. A gastroscopy and a contrast swallow exam using radio-opaque markers do not show any fistulas, but peroperative surgical exploration discovers a gastro-gastric fistula. This video clearly shows all the technical aspects of a revisional bariatric procedure.

Minimally invasive video-assisted parathyroidectomy for primary hyperparathyroidism
In recent years, the advances in preoperative localization studies, the availability of intraoperative parathyroid hormone (PTH) assay and the introduction of cervicoscopy revolutionized the surgical treatment of primary hyperparathyroidism (PHPT).
Minimally invasive video-assisted parathyroidectomy (MIVAP) is an efficacious and feasible procedure with the same complication rate as conventional surgery and has significant advantages in terms of cosmetic results, postoperative pain, recovery, and patient satisfaction. MIVAP should be considered a valid and validated option for the treatment of sporadic primary hyperparathyroidism, especially in case of a suspected single adenoma. This video demonstrates a minimally invasive approach for the excision of a right superior parathyroid adenoma in an inter-crico-thyroid position in a 65-year-old female patient.
