Reduced-Port Sleeve Gastrectomy for Morbidly Obese Japanese Patients: a Retrospective Case-Matched Study.

Background: Reduced-port laparoscopic surgery remains controversial due to technical challenges that can lead to suboptimal outcomes, and data pertaining to operative and clinical outcomes of reduced-port sleeve gastrectomy (RPSG) vs. conventional laparoscopic sleeve gastrectomy (CLSG) are lacking.

Aims: This retrospective case-matched study aimed to compare midterm (2-year) outcomes of RPSG and of CLSG.
