This randomized controlled trial aims to evaluate the efficacy of pancreatic parenchymal N-Butyl-2-Cyanoacrylate (NBCA) injection in reducing the incidence and severity of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD). POPF remains a major complication of PD, leading to increased morbidity, mortality, and healthcare costs. NBCA, a tissue adhesive, has shown promise in various surgical applications due to its hemostatic and sealing properties. This study will enroll approximately 90 patients undergoing PD, randomly assigning them to either the NBCA injection group or the control group. The primary outcome will be the incidence of POPF according to the International Study Group on Pancreatic Surgery (ISGPS) definition. Secondary outcomes includes length of hospital stay, readmission rates, reoperation rates, mortality, and other postoperative complications. This trial is designed to provide high level evidence regarding the utility of NBCA in improving outcomes after PD.
