Comparison of standard circular stapler anastomosis with or without circumferential suture enhancement in patients with robot-assisted Ivor-Lewis oesophagectomy due to malignant tumours of the oesophagus and oesophagogastric junction-a multi-centre, randomised, superiority study (STITCHES).

ABSTRACT:

Background

Morbidity due to anastomotic leakage is a major concern in transthoracic oesophagectomy. The aim of this randomised trial is to evaluate whether a circumferential suture reinforcement of the stapled end-to-side anastomosis in robot-assisted minimally invasive Ivor-Lewis oesophagectomy (RAMIE) leads to a reduced incidence of anastomotic leakages in the postoperative course.

Methods/design

This is a multi-centre randomised, double-blind, superiority trial with an adaptive sample size design undergoing RAMIE for malignant tumours. Patients will be randomised 1:1 into two study arms. In study arm A, participants will receive a standard circular-stapled end-to-side oesophagogastric anastomosis, while in study arm B, the anastomosis will have a circumferential suture re
