Background
Anastomotic leak after gastroesophageal surgery is a life-threatening complication. Self-expanding metal stent (SEMS) implantation or endoscopic vacuum therapy (EVT) have been established as alternatives to reoperation. This study compares the outcome of both interventions for anastomotic leak clinical management.
Methods
In this retrospective study, we identified all patients who received SEMS or EVT for anastomotic leaks after oncological gastroesophageal surgery between January 2007 and December 2016. Only patients with type II leaks according to the Esophagectomy Complications Consensus Group were included. Sealing rates, intervention-related complications, demographic characteristics, clinical history, leak characteristics, therapy duration, and in-hospital mortality were analyzed.
Results
One hundred eleven patients who received SEMS (n = 76) or EVT (n = 35) were identified and categorized by primary and final treatment. The overall closure rate in the final treatment analysis was 85.7% for EVT and 72.4% for SEMS (p = 0.152). ICU stay ranged from 0 to 60 days (median 6 days) for EVT and from 0 to 295 days (median 9 days) for SEMS (p = 0.704). EVT patients were hospitalized for 19–119 days (median 39 days) and SEMS patients for 13–296 days (median 37 days; p = 0.812). Demographic factors, comorbidities, and surgical parameters did not correlate with treatment or treatment success.
Conclusions
SEMS and EVT show comparable results for anastomotic leak management after oncologic gastroesophageal surgery. No superior outcome could be found for either one of the two treatments options.
