Abstract
Abstract One of the main complications related to esophagogastric surgery, due to esophageal and gastric cancer, is the anastomotic leak. The placement of endoluminal stents is the most frequent endoscopic therapy in these cases. However, since its introduction, endoscopic vacuum therapy has been shown to be a promising alternative. This study primarily aims to evaluate the efficacy and safety of endoscopic vacuum therapy for the treatment of anastomotic leak in esophagectomy and total gastrectomy. Methods A systematic review and meta-analysis was performed. Studies that evaluated the use of endoscopic vacuum therapy for anastomotic leak in esophagectomy and total gastrectomy were included. Results Twenty-three articles were included. A total of 559 patients were evaluated. Endoscopic vacuum therapy showed a fistulous orifice closure rate of 81.6% (rate: 0.816; 95% CI: 0.777–0.864) and, when compared to the stent, there is a 16% difference in favor of endoscopic vacuum therapy (risk difference [RD]: 0.16; 95% CI: 0.05–0.27). The risk for mortality in the endoscopic vacuum therapy was 10% lower than in endoluminal stent therapy (RD: −0.10; 95% CI: −0.18 to −0.02). Conclusion Endoscopic vacuum therapy might have a higher rate of fistulous orifice closure and a lower rate of mortality, compared to intraluminal stenting.
