About

Between March 2019 and September 2022 in our centre, R anastomosis was performed on 123 patients undergoing TLDG for distal gastric cancer. A retrospective review of a prospectively collected database identified patients who underwent TLDG between January 2010 and September 2022. Patients who underwent R anastomosis were matched in a 1:1 ratio with patients who underwent conventional anastomosis using a propensity score based on age, sex, preoperative BMI, American Society of Anesthesiologists (ASA) score, and the history of abdominal surgery. Surgical and postoperative outcomes and clinicopathological data were analyzed for both groups.

Enrollment: 246 patients

Sex: All

Ages: 35 to 80 years old

Volunteers: No Healthy Volunteers
