Abstract
Anastomotic leakage is a feared complication after esophagectomy and associated with increased post-operative morbidity and mrotality. The aim of this study was to evaluate the management of leakage after robot-assisted minimally invasive esophagectomy (RAMIE) with intrathoracic anastomosis. From a single center prospectively maintained database, all patients with anastomotic leakages defined by the Esophageal Complications Consensus Group between 2016 and 2021 were included. Contained leakage was defined as presence of air or fluid at level of the anastomosis without the involvement of the mediastinum or thorax. Non-contained leakage was defined as mediastinitis and/or mediastinal/pleural fluid collections. The primary outcome was 90-day mortality and the secondary outcome was successful recovery. In this study, 40 patients with anastomotic leakage were included. The 90-day mortality rate was 3% (n = 1). Leakage was considered contained in 29 patients (73%) and non-contained in 11 patients (27%). In the contained group, the majority of the patients were treated non-surgically (n = 27, 93%) and management was successful in 22 patients (76%). In the non-contained group, all patients required a reoperation with thoracic drainage and management was successful in seven patients (64%). Management failed in 11 patients (28%) of whom 7 developed an esophagobronchial fistula, 3 had a disconnection of the anastomosis and 1 died of a septic bleeding. In conclusion, this study demonstrates that the management anastomotic leakage in patients who underwent RAMIE with an intrathoracic anastomosis was successful in 73% of the patients with a 90-day mortality rate of 3%. A differentiated approach for the management of intrathoracic anastomotic leakage is proposed.
