Robotic Versus Laparoscopic Right Hemicolectomy With Complete Mesocolic Excision

Robotic Versus Laparoscopic Right Hemicolectomy With Complete Mesocolic Excision: a Retrospective Multicenter Study With Propensity Score Matching

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.

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.

Inclusion Criteria:

1. Adenocarcinoma was confirmed by preoperative colonoscopy and it was located in the right colon.
2. Preoperative enhanced abdominal CT examination showed no invasion of abdominal wall or adjacent organs.
3. The patient underwent robotic or laparoscopic right hemicolectomy with CME.

Exclusion Criteria:

1. Multiple primary colorectal tumors
2. Metastasis to abdominal
3. Pelvic or distant organs
4. Accompanied with bowel obstruction or perforation
5. Neuroendocrine tumors
6. Lymphomas
7. Other malignant tumors.
