Resection Margin of Transverse Colon Cancer With Extracorporeal Versus Intracorporeal Anastomosis

Overview

The approach of anastomosis in laparoscopic resection of transverse colon cancer (TCC) has rarely been discussed. This study aims to compare the resection margin of TCC with extracorporeal anastomosis (ECA) versus intracorporeal anastomosis (ICA). Patients who underwent laparoscopic resection of TCC from August 2019 to July 2021 in 13 participating centers are included in this study. According to the approach of anastomosis, patients are divided into two groups, ECA group and ICA group respectively. The clinical characteristics, the perioperative outcomes and the pathological results (especially the length of resection margin) are compared between the two groups. The length of two-sided resection margins (long margin, short margin) are measured on formalin-fixed specimens and those with short margin less than 4.0 cm are defined as unqualified specimens.

13 participating centers are as follows: Ruijin Hospital, Shanghai Jiaotong University School of Medicine；Zhejiang University Medical College Affiliated Sir Run Shaw Hospital；Zhongshan Hospital Affiliated to Fudan University；Renji Hospital Affiliated to Medical College of Shanghai Jiaotong University; Jiangsu Provincial People's Hospital; Xiangya Hospital of Central South University; The First Affiliated Hospital of Chongqing Medical University; The first hospital of Jilin University; Beijing Friendship Hospital Affiliated to Capital Medical University; Tangdu Hospital; Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of science and technology; Cancer Hospital of Chinese Academy of Medical Sciences; Henan Provincial People's Hospital
