LEAKAGE
All patients treated with EVT for anastomotic leakage after upper GI surgery at Amsterdam UMC between January 2018 and October 2021 were included: retrospectively (January 2018 to June 2021) and prospectively (until October 2021). Data were collected from a prospectively maintained database of patients undergoing upper GI surgery, including salvage resections; details regarding EVT were collected retrospectively. The diagnosis of anastomotic leakage was based on computed tomography (CT) scan findings, such as extraluminal oral contrast, and/or endoscopic findings, such as visualization of a transmural defect.This study was assessed by the local medical ethics committee, who waived the need for formal ethical review.
