Outcome of prophylactic endoscopic vacuum therapy for high-risk anastomosis after esophagectomy.

Background

Endoscopic vacuum therapy (EVT) has become an established procedure for the treatment of anastomotic leaks (AL) in upper gastrointestinal surgery. A novel approach is the use of EVT for preventing leaks in high-risk anastomosis. The aim of this study was to analyze the outcome of prophylactic EVT (pEVT) in patients receiving surgical revision of the anastomosis after oncological Ivor-Lewis esophagectomy (ILE) due to AL.Material and methods: Between June 2016 and February 2019, all patients who underwent anastomotic revision after ILE due to a confirmed AL were included. The primary outcome was the success rate of pEVT, which was defined as absence of an AL after revision. Secondary outcome parameters were duration of treatment, inflammatory levels, and ICU/hospital stay.

Results

Twenty-one patients underwent anastomotic revision due to an AL. The cause of the AL was ischemia in nine patients (42.9%) and non-ischemia (other) in 12 patients (57.1%). PEVT was performed in 14 patients (66.6%). The overall success rate of pEVT was five out of 14 patients (35.7%).

Conclusions

Prophylactic EVT cannot prevent a re-leak in patients with high-risk anastomosis due to surgical revision of an AL after oncological ILE. However, pEVT might help to control the clinical condition of these patients.
