Abstract
The evolution of laparoscopic surgery in gastric cancer has advanced significantly, with benefits over open surgery initially demonstrated in early gastric cancer and later in advanced stages. This study aims to evaluate postoperative complications, surgical outcomes, and anastomosis safety by comparing laparoscopic gastrectomy and laparoscopic-assisted gastrectomy. This retrospective, observational, analytical study included patients diagnosed with gastric cancer who underwent laparoscopic gastrectomy at a university hospital from January 2006 to February 2018. Patients were initially divided into two groups based on the type of anastomosis: laparoscopic gastrectomy (intracorporeal anastomosis) and laparoscopic-assisted gastrectomy (extracorporeal anastomosis). Further secondary analysis was done with subgroups based on the type of gastrectomy and anastomosis performed. A total of 139 patients were analyzed, showing significant differences in postoperative complications between the two surgical approaches. The laparoscopic-assisted group exhibited a higher rate of complications. The laparoscopic approach (with intracorporeal anastomosis) was found to have a lower risk of complications and morbidity/mortality compared to the laparoscopic-assisted approach. Laparoscopic gastrectomy with intracorporeal anastomosis resulted in lower morbidity and mortality than laparoscopic-assisted gastrectomy. The technique of partial gastrectomy with intracorporeal anastomosis was associated with the lowest rate of postoperative complications.
