Blunt pancreatic trauma: experience at a rural referral center.

The objective of this study was to compare mechanism of injury, treatment methods, and outcome of blunt pancreas trauma patients transferred from another hospital to those of patients brought directly from the scene. A retrospective review was conducted of 6078 patients treated at a Level I trauma center from 1/1/90 to 12/31/94. Blunt pancreas injury was found in 39 (0.64%) patients (mean age, 33.2 years). Mechanism of injury included 34 (87%) motor vehicle crashes, 3 (8%) motorcycle crashes, and 2 (5%) other injuries. There were 11 transfer patients (28%), and 28 (72%) admitted directly from the scene. Eighty-two per cent of the motor vehicle crash patients were unrestrained, and 35 per cent had ethanol intoxication. Exploratory laparotomy was performed on 32 (82%); eight (25%) required repair or resection; 22 (69%) had trivial injuries, at most requiring drainage; and two (6.3%) exsanguinated. No patients required Whipple resection or pancreatiocojejunostomy. At operation, an average of 2.5 associated intra-abdominal injuries were found. Overall survival was 35 of 39 (90%). Among the patients brought directly to the trauma center, 93 per cent survived, whereas survival among transferred patients was 82 per cent (chi2 = 0.19; P = 0.66). Blunt pancreatic injuries vary in severity, but radical resection is rarely required. Lack of safety restraint and ethanol use are major risk factors. Despite the high likelihood of associated injuries, survivability is high. No difference in outcome was seen between directly admitted and transferred patients.
