Note from the WeBSurg-IRCAD Scientific Committee: This video entitled “Segmental left colectomy: a modified caudal-to-cranial approach" shows an original technique of segmental colonic resection for benign conditions. Although, in the present case, the indication is not specified, there seems to be a tattooing on a lesion, which would not correspond to the initial indication of benign conditions. The indication might be a polyp. Such indications remain rare. The given approach is difficult to perform for inflammatory pathologies generating significant adhesions. However, although the video quality is not ideal, it was decided to publish this film with a special mention “case for debate” stating that this is not the IRCAD position, but the technique can be discussed. Note from the authors of the video: We have designed a modified caudal-to-cranial approach to perform a laparoscopic left colectomy preserving the inferior mesenteric artery for benign colorectal diseases. A dissection is performed to separate the descending mesocolon from the plane of Gerota's fascia from the medial aspect to the peritoneal lining to the left parietal gutter. The peritoneal layer is incised parallel to the vessel and close to the colonic wall. The dissection is continued anteriorly up to reach the resected parietal gutter. A passage into the mesentery of the upper rectum is created for the use of the stapler and the dissection of the rectum. These maneuvers allow to straighten the mesentery simplifying the identification and division of the sigmoid arteries. A caudal-to-cranial dissection of the mesentery is performed from the divided rectum to the proximal descending colon using a sealed envelope device. It can be very useful to mobilize the colon in any direction: laterally, medially, or upward. The dissection is performed along the course of the vessel up to the proximal colon, with progressive division of the sigmoid arterial branches. The specimen is extracted through a Pfannenstiel incision. The anastomosis is performed transanally with a circular stapler according to the Knight-Griffen technique.
