Local complications following pancreatic trauma

Abstract

Background: Major trauma to the pancreas is uncommon, but associated with significant overall morbidity and mortality. A vast majority of these adverse outcomes can be attributed to the presences of associated injuries. Among those patients who survive the initial injury, however, the subsequent development of pancreas-related complications represents a significant source of adverse outcomes.

Methods and results: A total of 257 patients admitted from January 1996 to April 2007 were identified from the trauma registry database at our institution. One hundred and eighty-three patients surviving more than 48 h after admission were selected for analysis. These patients were grouped according to the surgical management utilised to address their pancreatic injuries: either resection or operative drainage. After exclusion of patients with associated vascular injuries, those undergoing drainage had lower rate of associated hollow viscus injuries (51.9% vs. 69.9%; p = 0.016) and lower rates of associated solid organ injuries (44.2% vs. 70.9%; p < or = 0.001). Patients undergoing drainage were noted to have a higher incidence of pseudocyst formation (19.5% vs. 9.0%; OR: 2.47, 95% CI, 0.92-6.67; p = 0.068), but lower hospital lengths of stay (18.7+/-18.5 vs. 33.8+/-63.5; p = 0.001). No difference in mortality was noted between the two populations (5.7% vs. 3.0%; p = 0.700). After multivariate analysis pseudocyst formation was the only complication that proved different between the two management groups, with patients undergoing operative drainage more commonly developing this adverse sequela (OR: 2.93, 95% CI, 1.02-8.36; p = 0.041).

Conclusions: In the absence of vascular injury, the choice of surgical management did not affect adjusted mortality or the overall occurrence of pancreas-related complications. Individuals treated with operative drainage alone, however, were significantly more likely to develop a post-operative pseudocyst than their resectional counterparts.
