Development of a novel tool to assess skills in laparoscopic gastrectomy using the Delphi method: the Japanese operative rating scale for laparoscopic distal gastrectomy (JORS-LDG)

Background Assessment of the performance of laparoscopic gastrectomy is yet unreported, likely because of the complexity of the procedure. We aimed to develop a tool to assess the skills required for laparoscopic distal gastrectomy (LDG) through cognitive task analysis (CTA) and expert consensus using the Delphi method.
