[The therapeutic experience of blunt pancreatic trauma].

Objective: To summarize the experience of treatment for blunt pancreatic trauma. Methods: The clinical data of 52 patients with blunt pancreatic trauma admitted to the Department of Pancreatic and Biliary Surgery of the First Affiliated Hospital of Harbin Medical University from January 2013 to June 2018 were analyzed retrospectively.There were 40 male and 12 female patients, aging from 12 to 112 years with a median age of 35.5 years.According to the organ injury scale by American Association for the Surgery of Trauma(AAST) for pancreatic injury severity, 15 cases were in grade Ⅰ(28.8%), 20 cases were in grade Ⅱ(38.5%), 10 cases were in grade Ⅲ(19.2%),5 cases were in grade Ⅳ(9.6%) and 2 cases were in grade Ⅴ(3.8%). Isolated blunt pancreatic trauma occurred in 11(21.2%) patients including 5 cases of grade Ⅰ,5 cases of grade Ⅱ and 1 case of grade Ⅲ, and associated injuries existed in 41 patients(78.8%). Results: Among 52 patients, 36 patients(69.2%) were transferred from other hospitals and 16(30.8%) patients were admitted through the emergency department. Finally, 49 patients(94.2%) were cured and 3 patients (5.8%) died.For the 15 cases of grade Ⅰ,9 patients were managed non-operatively, 5 cases underwent peritoneal lavage and drainage after surgery for the other injured abdominal organs, and 1 patient received percutaneous catheter drainage(PCD) with non-operative treatment. For the 20 cases of grade Ⅱ,4 cases only received non-operative treatment and 2 cases also received PCD. Besides, 2 cases underwent debridement and drainage for peripancreatic necrotic tissue and external drainage for pancreatic pseudocyst retrospectively after about 25 days of getting injured. As for patients who received exploratory laparotomy, 5 patients underwent suture repair associated with external drainage, and 7 patients were managed only with external drainage. For the 10 cases of grade Ⅲ,6 patients were cured through distal pancreatectomy and splenectomy with external drainage, while 2 patients underwent endoscopic retrograde cholangiopancreatography and ductal stenting, and the other 2 patients just received debridement and drainage for peripancreatic necrotic tissue.For the 5 cases of grade Ⅳ,2 patients underwent jejunostomy and abdominal cavity drainage, 1 patient had a pancreaticoduodenectomy with drainage,1 patient received suture repair of the pancreas and pancreaticojejunostomy, and 1 patient was managed with suture repair of the head of pancreas and external drainage.For the 2 patients of grade Ⅴ,1 patient received exploratory laparotomy and gauze compression packing hemostasis, and the other patient underwent pancreaticoduodenal repair, gastrointestinal anastomosis, duodenal exclusion surgery and external drainage. Conclusion: According to the AAST classifications, associated injuries, physiological status and intraoperative situation, it could be better to make a comprehensive judgment, achieve early diagnosis and take appropriate individualized treatment strategy, and to improve the overall therapeutic effect for blunt pancreatic trauma.
