For the American Association for the Surgery of Trauma Organ Injury Scale (AAST-OIS) Grade IV injuries, pancreaticoduodenectomy is often considered the only definitive option; however, its invasiveness and risk of long-term endocrine and exocrine dysfunction create a major dilemma when pancreaticoduodenectomy may be disproportionate to the anatomic injury. Practical pancreas-preserving strategies remain poorly defined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>A 25-year-old male sustained a self-inflicted stab wound causing hemorrhagic shock, generalized peritonitis due to gastric perforation, and AAST-OIS Grade IV pancreatic head injury with complete MPD transection. Initial management consisted of staged damage-control surgery with peri-pancreatic gauze packing and negative-pressure therapy for hemorrhage and contamination control. After physiological stabilization, delayed reconstruction was performed using total pancreas-preserving pancreatic injury-site jejunostomy (PP-PIJ), in which viable pancreatic tissue surrounding the injury site was anastomosed to a Roux-en-Y jejunal limb without pancreatic resection. The postoperative course was complicated by a subfascial abdominal wall abscess with wound dehiscence requiring drainage and abdominal wall re-closure; however, no pancreatic fistula or anastomotic failure occurred, and pancreatic function was preserved.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This report describes the first adult application of PP-PIJ and proposes a pancreas-preserving reconstructive option for traumatic pancreatic head injury with MPD transection. Staged damage-control surgery may serve as a platform for delayed reconstruction. The accompanying decision algorithm may assist operative selection when pancreaticoduodenectomy may be disproportionate to the anatomic injury.<\/jats:p>\n
