Summary

the investigators performed a retrospective multicenter propensity score matching study. From July 2016 to July 2021, 382 consecutive patients from different Chinese surgical departments were available for inclusion out of an initial cohort of 412, who underwent robotic or laparoscopic right hemicolectomy with CME.

Detailed description

All consecutive patients who underwent robotic or laparoscopic right hemicolectomy with CME from July 2016 to July 2021 at three Chinese surgical departments (Department of General Surgery, Army Medical Center, Chongqing;Department of Colorectum, Chongqing University Three Gorges Hospital, Chongqing;Department of Colorectum, the 940th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army, Lanzhou) were included in the study. A retrospective review of multicenter institutional database was conducted. The Da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) has been employed since 2016 in three centers. From July 2016 to July 2021, an initial cohort of 412 consecutive patients underwent robotic or laparoscopic right hemicolectomy with CME in three departments. With 30 cases meeting the exclusion criteria, 382 cases, including 204 males and 178 females, were available for inclusion. Of these, 149 cases by robotic right hemicolectomy with CME were classified as the robotic group, while the other 233 cases by laparoscopic right hemicolectomy with CME as the laparoscopic group.

Interventions

Type	Name	Description
PROCEDURE	robotic right hemicolectomy with CME	The distribution of trocars was placed according to the position of Intuitive Surgical Inc. for robotic colectomy. The robot was set to come and dock from theright shoulder of the patient. Three robotic 8-mm trocars (R1, R2 and R3) and two 12-mm trocars (camera and assistant port) were used for the robotic procedure. One working arm carrying a monopolar cautery hook for dissection was located in the left upper quadrant port (R1). The other two working arms carried bipolar forceps in the suprapubic port (R3), and Cadiere's fenestrated forceps in the right lower quadrant port (R2) that was used to keep the superior mesenteric axis in traction. After gentle cephalad traction on the transversemesocolon with the grasp in R2, the assistant grasped the ileocecal valve through the assistant port to put the ileocolic vascular pedicle on tension and the ileocolic vessels were identified and lifted up with R3.
