Proximal gastrectomy versus total gastrectomy for adenocarcinoma of the esophagogastric junction: a meta-analysis

Abstract

Aim: To compare efficacy between total gastrectomy (TG) and proximal gastrectomy (PG) for upper-third gastric cancer. Materials & methods: PubMed, Embase and Cochrane library were searched to select suitable researches. Stata was used for meta-analysis including 5-year overall survival rate, recurrence rate, complication morbidities and serum nutritional levels. Results: Ten retrospective English researches were contained. Our study showed no significant difference of 5-year overall survival rate, recurrence rate, reflux symptoms and anastomotic leakage. TG experienced longer operation time, more lymph nodes-retrieved number, more estimated blood loss and higher ileus, but less anastomotic stricture. PG showed advantages over TG in terms of serum nutritional levels. Conclusion: PG is more preferable to TG for treatment of upper-third gastric cancer.
