Multi-institutional Study on the Assessment of Robotic Surgery for Gastric Cancer

Yonsei University1,650 enrolled

Overview

Minimally invasive surgery revolutionized the field of gastric cancer surgery. The surgical robot was introduced to alleviate the difficulty of laparoscopic surgery. Although many studies have reported successful outcomes for robotic surgery, there is no multicenter prospective analysis regarding the advantage of the robotic gastrectomy. The aim of this study is to analyze the surgical outcomes of the robotic gastrectomy focusing on the learning curve, cost-effectiveness, quality of life, and acute-inflammatory reaction in comparison with laparoscopic gastrectomy.

Outcomes

Primary Outcomes

Registration of all robotic gastrectomies performed in South Korea

Time frame: at the end of the study

Learning curve (operation time and surgical outcome) of robotic gastrectomy

Time frame: from the start of the operation to discharge of the patient (usually two weeks after the operation)

Cost-effectiveness comparison between robotic and laparoscopic gastrectomy

Time frame: from admission to discharge of the patient (usually from two days before the operation until two weeks after the operation)

Quality of life after robotic and laparoscopic gastrectomy

Time frame: One day before operation, first OPD visit after the operation (two weeks after the operation), 3M, 12M, 36M, and 60M after the operation

Acute-inflammatory response after undergoing robotic and laparoscopic gastrectomy

Time frame: preop, 2hr, 24hr, 4days and 30 days after the operation
