BACKGROUND: In the treatment of patients with pancreatic injury, the focus of attention is usually on main ductal injuries. METHODS: To develop a classification system for pancreatic ductal injuries, we retrospectively analyzed blunt pancreatic injuries in 40 patients. We assessed the relationships between findings on pancreatography (36 endoscopic retrograde procedures and 4 transduodenal procedures), the treatment modality, and the clinical course. RESULTS: Patients with class 1 injuries (radiographically normal ducts, n = 13) could be treated nonsurgically without major complications. Patients with class 2 injuries (branch injuries, n = 7), in whom contrast medium from ductal branches did not leak from the pancreatic parenchyma (class 2a, n = 3), could be treated nonsurgically. Patients with leaks into the retroperitoneal space (class 2b, n = 4) required at least a drainage laparotomy. Patients with class 3 injuries (main duct injuries, n = 20), including two patients in whom conservative treatment resulted in severe complications, required laparotomy. CONCLUSION: This classification system for pancreatic ductal injuries may facilitate the selection of appropriate therapeutic modalities for patients with blunt pancreatic injury.
