About

While robotic gastrectomy (RG) is increasingly used in gastric cancer surgery, its potential advantages over laparoscopic gastrectomy (LG) in Intraoperative technical complexity (ITC) cases remain debated.

Full description

This retrospective cohort study included 3,534 patients with gastric cancer who underwent radical gastrectomy at eight high-volume hospitals. ITC was defined by any of the following criteria: operative time exceeding the third quartile, intraoperative estimated blood loss ≥ 400 mL, or conversion to open surgery. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were conducted to compare short- and long-term outcomes.

Enrollment: 3,534 patients

Sex: All

Volunteers: No Healthy Volunteers
