Laparoscopic completion gastrectomy: A single‐institution case series and systematic review of the literature

Le résumé fourni par la source

INTRODUCTION: Completion gastrectomy with lymphadenectomy for remnant gastric cancer (RGC) is currently the gold standard for patients with resectable disease. Multiple surgical approaches can be adopted; however, there exists no agreement on the best choice due to the low incidence of RGC. With its anticipated increase in prevalence, we thus sought to evaluate the feasibility and efficacy of the laparoscopic approach versus conventional laparotomy via a pooled analysis of existing literature. METHODS: A retrospective review of five consecutive patients who underwent laparoscopic completion gastrectomy from August 2017 to June 2022 was performed following Institutional Review Board waiver. A comprehensive systematic review of literature on laparoscopic completion gastrectomy from the Pubmed, Embase, MEDLINE, Web of Science and Cochrane databases was conducted to supplement the experience from our institution. RESULTS: Four patients had prior benign gastric disease and one had prior gastric cancer. Two patients experienced severe postoperative complications but there were otherwise no reports of conversion to laparotomy or mortality. Mean operative duration was 295 minutes. Mean duration to oral intake and discharge was 6.8 and 14.6 days respectively. Results from our pooled analysis of 591 cases suggested that the laparoscopic approach was associated with longer operative durations but delivered fewer postoperative complications, shorter duration to dietary resumption and shorter lengths of stay over conventional laparotomy. CONCLUSION: Laparoscopic completion gastrectomy is indeed a more challenging procedure due to the presence of dense adhesions from previous surgery. However, the procedure can be performed safely with superior outcomes as compared to conventional laparotomy.
