Abstract
Purpose: To characterize injury patterns and institutional trends associated with the utilization of laparoscopy in the management of pediatric abdominal trauma. Methods: The National Trauma Data Bank (2010–2014) was queried for encounters involving patients ≤14 years who underwent an open or laparoscopic abdominal operation within 48 hours of emergency department arrival. Patient, injury, and hospital characteristics associated with each approach were identified. Multivariate logistic regression was used to evaluate the influence of patient and hospital characteristics on operative approach. Results: Laparoscopy comprised 7.8% ( n = 355) of all abdominal trauma operations. Patients undergoing laparoscopy had lower injury severity scores and higher Glasgow Coma Scale scores on arrival compared with laparotomy subjects ( P < .001). Laparoscopic patients also had a shorter length of hospital stay (5.0 versus 8.6 days, P < .001), but longer time to the operating room (9.2 versus 6.3 hours, P < .001) compared with their open counterparts. The proportion of cases managed laparoscopically increased from 6.2% in 2010 to 10.1% in 2014 ( P = .013), with increase in utilization primarily driven by university hospitals ( P = .026) and level I pediatric trauma centers ( P = .043). Conversion to laparotomy was uncommon (18.6%), and mortality in the laparoscopic cohort was low (0.4%). Conclusions: Use of laparoscopy has increased in the pediatric abdominal trauma population, typically in a less injured cohort of patients. As familiarity with and availability of minimally invasive techniques increase, this trend will likely continue.
