Operative vs Nonoperative Management of Pediatric Blunt Pancreatic Trauma: Evaluation of the National Trauma Data Bank

Abstract

Background: Traumatic pancreatic injury is associated with significant morbidity and mortality. We evaluated the differences in outcomes among children with blunt pancreatic injuries managed operatively and nonoperatively.

Study design: The National Trauma Data Bank was evaluated from 2002 to 2011. Patients less than18 years of age with blunt pancreatic injuries and Abbreviated Injury Scale (AIS) scores ≥ 3 were identified. Patients were divided into nonoperative (NO), operative (O), and delayed operative (DO; operation performed 48 hours or more after admission) groups. Outcomes evaluated were total length of stay (LOS), ICU use/LOS, complications, and death. Univariate comparisons were performed using Fisher's exact and Kruskal-Wallis rank tests. Multivariable analyses were performed using robust regression and logistic regression.

Results: There were 424 cases analyzed. Mean (± SD) age was 10.6 ± 5.3 years, and mean Injury Severity Score (ISS) was 23.4 ± 13.4. Operative groups differed by age (p = 0.002), AIS severity (p = 0.04), and concomitant head injury (p = 0.01), but were similar with regard to sex, race, and ISS. Length of stay was significantly higher in the DO group compared with the NO or O groups; the NO group had the lowest LOS (covariate-adjusted: 18.7 days vs 11.8 days, p < 0.001 and 12.6 days, p < 0.001, respectively) and infection rates (10.2% vs 1.6% and 6.2%, respectively, p = 0.04). The ICU LOS was greatest in the DO group (vs NO, p = 0.03; O, p = 0.29), as was the likelihood of ICU use (vs NO, p = 0.02; O, p = 0.75). Groups did not differ with respect to outcomes including death (p = 0.94) and overall complication rate (p = 0.63).

Conclusions: Overall, children managed nonoperatively have equivalent or better outcomes when compared with operative and delayed operative management in regard to death, overall complications, LOS, ICU LOS, and ICU use.
