Comparisons of perioperative and survival outcomes of laparoscopic versus open gastrectomy for serosa-positive (pT4a) gastric cancer patients: a propensity score matched analysis

Data about whether laparoscopic gastrectomy (LG) is applicable in serosa-positive (pT4a) gastric cancer patients remain rare. The purpose of this study is to compare the perioperative and long-term outcomes between the laparoscopic and open gastrectomy (OG) in pT4a gastric cancer patients who underwent curative resection. A total of 1086 consecutive pT4a patients (101 patients with LG and 985 with OG) who underwent curative gastrectomy in a...
