Abstract
BACKGROUND: Laparoscopic extended right hemicolectomy is regarded as one of the more difficult procedures in colorectal surgery due to the complexity of the dissection around the pancreatic neck to identify the origin of the middle colic artery.1 Proper identification and ligation of the middle colic artery at its origin is paramount to achieve complete mesocolic excision.2 (,) 3 We describe our technique of middle colic vessels dissection in a laparoscopic extended right hemicolectomy.
METHODS: Our patient was a 58-year-old female with a stenosing transverse colon adenocarcinoma. The video highlights the key steps of a laparoscopic extended right hemicolectomy with special attention to the dissection and identification of the origin of the middle colic vessels at the pancreatic neck. We utilized a posterior-to-anterior approach for the dissection around the superior mesenteric pedicle.
RESULTS: By carefully skeletonizing the pancreas from the body to the neck, the superior mesentery pedicle is isolated and skeletonized to identify the origin of the middle colic vessels. A posterior-to-anterior approach is used to complete the skeletonisation before ligation of the middle colic vessels at its origin. Operative time was 288 min with an estimated blood loss of 40 ml. The patient recovered well without complications of pancreatitis and was discharged on postoperative day 5. Histology revealed a 4-cm moderately differentiated adenocarcinoma with 10 of 34 lymph nodes involved-pT3N2b.
CONCLUSIONS: With the increasing popularity of laparoscopic surgery, meticulous laparoscopic dissection of the middle colic vessels is feasible and safe and may potentially help to optimize oncological outcomes for laparoscopic extended right hemicolectomy.
