Autologous falciform ligament graft as A substitute for mesentericoportal vein reconstruction in pancreaticoduodenectomy

Abstract

ObjectiveTo evaluate the falciform ligament as an autologous substitute for mesentericoportal vein reconstruction during pancreaticoduodenectomy. BackgroundMesentericoportal vein reconstruction was needed in some certain cases during pancreaticoduodenectomy, and a rapidly available substitute was required. MethodsThe falciform ligament was used as an autologous substitute during pancreaticoduodenectomy in 6 patients between June 2016 and May 2017. Anticoagulation was not performed at any stage and venous patency was estimated by Color-Doppler ultrasonography and contrast-enhanced computed tomography. Results6 patients underwent vascular resection during pancreaticoduodenectomy for malignant tumors. The falciform ligament graft, with a mean length of 26 mm (10–40), was immediately harvested and used as a lateral patch for reconstruction of the mesentericoportal vein (n = 6). Severe morbidity included Clavien grade-III complications occurred in 1(16.7%) patients but there was no graft-related complications. Histological vascular invasion was present in all the patients (n = 6, 100%), and all had an R0 resection (100%). All venous reconstructions were patent (100%) after a mean follow-up of 12 (6–16) months. ConclusionsAn autologous falciform ligament graft can be safely used as a lateral substitute for mesentericoportal vein reconstruction during pancreaticoduodenectomy; this could help improve the radical resection rate of malignant tumors when oncologically required.
