Colonic injuries and the damage control abdomen: Does management strategy matter?

摘要

Background: The optimal management of colon injury patients requiring damage control laparotomy (DCL) is controversial. The objective of this study was to assess the safety of colonic resection and anastomosis versus fecal diversion in trauma patients requiring DCL. Methods: Patients with traumatic colon injuries undergoing DCL between 2000 and 2010 were identified by the database and chart review. Those who died within 48 h were excluded. Patients were divided into two groups: those undergoing one or more colonic anastomoses with or without distal colostomy (group 1) and those undergoing colostomy only or one or more colonic anastomoses with a protecting proximal ostomy (group 2). Variables were compared using Wilcoxon rank sum, χ2, or Fisher exact tests as appropriate. Results: Sixty-one patients were included (group 1, n = 28 and group 2, n = 33). Fascial closure rates (group 1, 50% versus group 2, 61%; P = 0.45), hospital length of stay (29 versus 23 d; P = 0.89), and in-patient mortality (11% versus 12%; P = 1.0) were similar between groups. There were a total of 11 anastomotic leaks, five of which were related to non-colonic enteric repairs. Colonic anastomosis leak rates were 16% overall (six of the 38 patients), 14% in group 1 (four of the 28 patients), and 20% in group 2 (two of the 10 patients). Compared with patients who did not leak, patients who leaked had a higher median age (37 versus 25 y; P = 0.05), greater likelihood of not achieving facial closure before post-injury day 5 (18% versus 2%; P = 0.003), and a longer hospital length of stay (46 versus 25 d; P = 0.003). Conclusions: Outcomes after colonic injury in the setting of DCL were similar regardless of the surgical management strategy. Based on these findings, a strategy of diversion over anastomosis cannot be strongly recommended.
