Background  The purpose of this study is to evaluate whether wrapping of the pedicled falciform ligamentum flap around the gastroduodenal artery (GDA) stump/hepatic artery can significantly decrease the incidence of erosion hemorrhage after pancreatoduodenectomy (PD).    Methods/design  This is a randomized controlled multicenter trial involving 400 patients undergoing PD. Patients will be randomized into two groups. The intervention group consists of 200 patients with a prophylactic wrapping of the GDA stump using the pedicled falciform ligament. The control group consists of 200 patients without the wrap. The primary endpoint is the rate of postoperative erosion hemorrhage of the GDA stump or hepatic artery within 3 months. The secondary endpoints are postpancreatectomy hemorrhage stratified according to the texture of the pancreas, postoperative pancreatic fistula (POPF), postoperative rate of therapeutic interventions, morbidity, and mortality.    Discussion  Only few retrospective studies investigated the effectiveness of a falciform ligament wrap around the GDA for prevention of erosion hemorrhage. Erosion hemorrhage occurs in up to 6–9% of cases after PD and is most frequently evoked by a POPF. Erosion hemorrhage is associated with a remarkable mortality of over 30%. The rate of hemorrhage after performing the wrap is reported to be low. However, there exist no prospectively controlled data to support its general use. Therefore, the presented randomized controlled trial will provide clinically relevant evidence of the effectiveness of the wrap with statistical significance.
