Laparoscopic IIeocecus-Sparing Right Hemicolectomy for Cancer of the Hepatic Flexure and Proximal Transverse Colon
View on ClinicalTrials.gov
Updated Dec 15, 2025
Brief Summary
To investigate whether laparoscopic ileocecus-sparing right hemicolectomy is feasible and oncologically safe
Detailed Description
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
Interventions
Name:
laparoscopic ileocecus-sparing right hemicolectomy
Type:
PROCEDURE
Description:
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.
Primary Outcomes
Measure:
Postoperative complications
TimeFrame:
up to 90 days after surgery
Description:
Postoperative complications used to calculate the Comprehensive Complication Index (CCI) will be recorded
Measure:
1-year local recurrence
TimeFrame:
7 days after surgery
Description:
rate of local recurrence one year after surgery, including anastomotic recurrence, recurrence around ileocolic vessels and surgical trunk of superior mesenteric vein,
