Following the principle of complete mesocolic excision(CME), Ileocecus-Sparing Right colectomy refers to the resection of the most portion of the ascending colon, hepatic flexure and mid to distal transverse colon. The extent of lymph node dissection and length of distal resection margin are similar to conventional right hemicolectomy. The length of proximal resection margin varies.

The ileocecal artery(ICA) is skeletonized. The colic branch of ICA is divided and ligated. Preserve anterior cecal artery, posterior cecal artery and ileocecal branch of ICA. Divide and ligate the right colic artery(RCA) and middle colic artery(MCA) at their roots. Dissect the lymph nodes surrounding the ICA, RCA and MCA accordingly. Head-to-Head colocolic anastomois is done, with circular stapler via making an opening at the bottom of cecum.

laparoscopic ileocecus-sparing right hemicolectomy

KeFeng Ding, PhD

To investigate whether laparoscopic ileocecus-sparing right hemicolectomy is feasible and oncologically safe

Our study is a single arm, single center clinical trial. The enrolled patients will accept laparoscopic ileocecus-sparing right hemicolectomy. The primary endpoint: postoperative complications, 1-year local recurrence. The second endpoint: conversion to conventional right hemicolectomy, time to first flatus after surgery, number of harvested lymph nodes, 3-year disease free survival, R0 resection, Specimen morphometry

Laparoscopic IIeocecus-Sparing Right Hemicolectomy for Cancer of the Hepatic Flexure and Proximal Transverse Colon

An Open, Single-arm, Single Center, Clinical Trial to Investigate the Feasibility and Safety of Laparoscopic Ileocecus-sparing Right Hemicolectomy for Cancer of the Hepatic Flexure and Proximal Transverse Colon

Postoperative complications used to calculate the Comprehensive Complication Index (CCI) will be recorded

rate of local recurrence one year after surgery, including anastomotic recurrence, recurrence around ileocolic vessels and surgical trunk of superior mesenteric vein,

the rate of conversion to conventional right hemicolectomy

days from a colectomy procedure to first occurrence of flatus during subject's postoperative recovery

Number of harvested Lymph nodes according to the pathological report

Rate of resection without any affected margins during the surgical procedure according to the pathological report

The gross dimensions of resected specimen: length, the distal and proximal resection margins distance, vascular pedicle length

the time from enrollment until disease relapse or death from any cause 3 years after surgery
