[Traumatic injuries of the pancreas: report of 65 cases]

With the aim of aiding the accurate diagnosis and treatment of patients with pancreatic injuries, we reviewed the medical records of sixty-five patients, treated for traumatic pancreatic lesions at the Department of Surgery of the University of São Paulo in the 5-year period from 1989 through 1993. Records, including operative and pathology reports, were reviewed and the location of the pancreatic injury, associated intra-abdominal injuries, type of injury, trauma scores, treatment, complications and mortality rates recorded. There were 58 male and seven female patients with a mean age of 28.3 years (range, 2-77 years). Of the 65 pancreatic injuries, 45 (69.2%) were caused by penetrating wounds and twenty by blunt trauma. The most frequent site of lesion was the head of the pancreas (38.5%). Associated injuries were found in all but five of the patients. In the 65 patients, 170 intra-abdominal injuries were found (2.6 per patient). Twenty-eight of the 65 patients (43.1%) had liver lacerations. Lacerations of major abdominal vessels (27 patients), gastric lacerations (25 patients) and colorectal lacerations (17 patients) were the next most frequent injuries. Fifteen out of twenty patients died within two days after the accident from severe concomitant injuries. Simple drainage was performed in 33 patients, distal pancreatectomy in 17 and duodenopancreatectomy in six patients. Pancreas-related complications occurred in 20 (30.7%) out of 57 patients who survived the initial operation. We concluded that the type of repair employed in our series was related to the class of injury and clinical conditions (based on trauma scores). Therefore, whenever possible, conservative management (no pancreatic resection) was employed in patients that sustained class I and II injuries and pancreatic resection in class III and IV injuries.
