The multicentre randomised controlled TRIANGLE trial aims to evaluate whether a more radical dissection along the superior mesenteric artery (SMA) and removal of all lymphatic and soft tissue between the celiac artery (CA), the mesenterico-portal axis (MPA) and the SMA (the so called “triangle”) during partial pancreaticoduodenectomy (PD) in comparison to conventional PD increases disease-free survival (DFS) in patients with carcinomas of the pancreatic head.
