Endoscopic vacuum therapy for post-esophagectomy anastomotic dehiscence as rescue treatment: a single center case series

Background Endoscopic vacuum therapy (EVT) represents an effective endoscopic technique for the treatment of post-esophagectomy leaks and can be used after failure of primary treatment. We aimed to investigate endoscopic data and success rate of EVT for post-esophagectomy anastomotic leaks, after failed redo surgery or previous endoscopic treatment. Methods We retrospectively recruited 12 patients from January 2018 to October 2020. Success was defined as dehiscence closure at radiological and/or endoscopic evaluation. Ethical Committee of our institution approved the study. Results Twelve patients (66.7% male, mean age 65.08 ± 16.7 years) affected by esophago-gastric ( n = 10) or esophago-jejunal ( n = 2) anastomosis dehiscences after oncologic surgery were treated with EVT, after failure of previous redo-surgical ( n = 3, 25%) or endoscopic management ( n = 9, 75%). Technical success rate was 100% (60/60 procedures) and dehiscence closure was achieved in three quarters of patients (9/12, 75%). Regarding complications, one case of sponge dislocation (1/60 = 1.7%) and another case of delayed stricture after post-EVT stent placement (1/60 = 1.7%) were recorded, during a mean follow up of 182.3 days. Conclusions EVT is a promising option in the treatment of the most complicated anastomotic dehiscences. Its use could be also considered after failure of previous endoscopic or surgical management.
