Totally laparoscopic splenic flexure resection for cancer
The objective of this video is to demonstrate a laparoscopic segmental oncological splenic flexure colonic resection for cancer. Splenic flexure carcinoma is a rare condition, as it represents 3 to 8% of all colon cancers. It is associated with a high risk of obstruction and a poor prognosis. The surgical approach is challenging and not fully standardized. The resected area must include the mesocolon with major vessels ligation at their origin, in order to reduce local recurrence via the complete removal of potentially involved lymph node stations.
The oncological effectiveness of a segmental resection could be determined by the peculiar lymphatic spread of splenic flexure cancers. Different studies showed that the majority of positive lymph nodes among patients with splenic flexure carcinoma are distributed along the paracolic arcade and the left colic artery. As a result, a segmental resection associated with a medial-to-lateral approach could be safe and effective. The experience with a totally laparoscopic approach with intracorporeal anastomosis is well described in the current literature. Additionally, an intracorporeal anastomosis minimizes the risk of bowel twisting, preventing the exteriorization of the stumps, and reducing bowel traction, which can affect anastomotic irrigation, especially in obese patients. In a setting of surgeons experienced with laparoscopic colorectal surgery, the outcomes of laparoscopic segmental resection of splenic flexure are similar to those of laparoscopic resections for cancer in other locations.

Laparoscopic right colectomy: bottom-to-up approach with intracorporeal anastomosis
Laparoscopic right colectomy (LRC) has become a well-established technique in colon cancer treatment achieving the same degree of radicality as open colectomy with the advantages of minimal invasion. A medial-to-lateral approach is the standard technique, but the bottom-to-up approach, with intracorporeal anastomosis (BTU), has recently gained popularity among surgeons.
Clinical case
The authors report the case of a 70-year-old male patient with persistent abdominal discomfort and a change in bowel habits. Preoperative staging revealed an adenocarcinoma at the hepatic flexure of the colon with no metastatic disease. The patient was proposed for a laparoscopic right colectomy.
A bottom-to-up approach was performed by opening an avascular plane posterior to the right mesocolon, creating a mesenteric route cranially along Gerota’s fascia until the duodenum and liver have been exposed. A side-to-side ileocolic intracorporeal stapled anastomosis was fashioned. The procedure and postoperative recovery were uneventful.
LRC using a BTU approach is a feasible and safe alternative to the conventional medial-to-lateral approach. The main advantages are a short learning curve and an easy access to the retroperitoneal space with direct visualization and protection of retroperitoneal structures. The performance of an intracorporeal anastomosis offers the advantage of a smaller extraction incision, lower wound-related complications, and fast recovery.
