Live interactive surgery: POEM for achalasia in a patient with a surgical history of subtotal gastrectomy

In this key lecture, Dr. Sosa Valencia focuses on the role of endoscopic ultrasound (EUS) in ampullary and submucosal tumors.

Currently, bariatric surgery offers the most durable results, but endoscopic procedures respecting the same principles are emerging. In this lecture, Dr. Galvao Neto presents the new endoscopic bariatric and metabolic procedures.

Endoscopic ultrasound-guided vascular procedures are challenging, considering the variety of vascular pathology. In this lecture, Dr. Barthet presents his experience with this complex procedure.

Endocytoscopy (EC) enables in vivo microscopic imaging at 1400-fold magnification, thereby allowing the analysis of mucosal structures at the cellular level. In this lecture, Dr. Minami describes this technique with detailed video and images.

In the current era, palliative stenting has emerged as an additional tool for advanced esophageal cancer. In this lecture, Dr. Wagner Colaiacovo presents the endoscopic procedure with stents for advanced esophageal cancer.

In this video, we present the performance of piecemeal endoscopic mucosal resection (EMR) for a duodenal sessile polyp after filling the duodenal lumen with water. The technical aspects of the procedure and detailed explanation of the tumor appearance are provided.

An intestinal polyp is a mass of tissue, which arises from the bowel wall and protrudes into the lumen. Polyps may be sessile or pedunculated. The incidence of polyps ranges from 7 to 50%. Polyps are most commonly found in the rectum and sigmoid colon and decrease in frequency towards the caecum.
Symptoms and signs:
Polyps are usually asymptomatic. The most frequent complaint is rectal bleeding, which is usually occult. Abdominal pain and obstruction occur with large polyps. The main concern with polyps is the risk of malignant transformation.
Complications of polypectomy: Common complications following polypectomy are bleeding and infection. The risk of bleeding ranges from 0.2 to 1.2%. When patients are on blood thinners, the risk of bleeding increases to 6.8%.
Advantages and disadvantages of use of prophylactic clips:
Clips can be applied during the procedure itself. They are easy to deploy. No scarring can be observed.
Disadvantages:
They are expensive, and present a risk of perforation and further bleeding.

Endoscopic submucosal dissection (ESD) is currently accepted as the major treatment modality for superficial neoplasms in the gastrointestinal tract including the esophagus. In this key lecture, Dr. Inoue presents the therapeutic strategy for leiomyomas of the esophagus and cardia.

In this lecture, Dr. Coron focuses on the role of radiofrequency ablation.
