Non-robotic minimally invasive gastrectomy as an independent risk factor for postoperative intra-abdominal infectious complications: A single-center, retrospective and propensity score-matched analysis

Abstract

BACKGROUND: Minimally invasive surgery for gastric cancer (GC) has gained widespread use as a safe curative procedure especially for early GC. AIM: To determine risk factors for postoperative complications after minimally invasive gastrectomy for GC. METHODS: Between January 2009 and June 2019, 1716 consecutive patients were referred to our division for primary GC. Among them, 1401 patients who were diagnosed with both clinical and pathological Stage III or lower GC and underwent robotic gastrectomy (RG) or laparoscopic gastrectomy (LG) were enrolled. Retrospective chart review and multivariate analysis were performed for identifying risk factors for postoperative morbidity. RESULTS: = 0.034] was a significant independent risk factor for intra-abdominal infectious complications. CONCLUSION: The findings showed that robotic surgery might improve short-term outcomes following minimally invasive radical gastrectomy by reducing intra-abdominal infectious complications.
