A prospective observational study of abdominal injury management in contemporary military operations: damage control laparotomy is associated with high survivability and low rates of fecal diversion
Abstract
Objective: This study describes the cause, management, and outcomes of abdominal injury in a mature deployed military trauma system, with particular focus on damage control, hollow visceral injury (HVI), and stoma utilization.
Background: Damage control laparotomy (DCL) is established in military and civilian practice. However, optimal management of HVI during military DCL remains controversial.
Methods: We studied abdominal trauma managed over 5 months at the Joint Force Combat Support Hospital, Camp Bastion, Afghanistan (Role 3). Data included demographics, wounding mechanism, injuries sustained, prehospital times, location of first laparotomy (Role 3 or forward), use of DCL or definitive laparotomy, subsequent surgical details, resource utilization, complications, and mortality.
Results: Ninety-four of 636 trauma patients (15%) underwent laparotomy. Military injury mechanisms dominated [44 gunshot wounds (47%), 44 blast (47%), and 6 blunt trauma (6%)]. Seventy-two of 94 patients (77%) underwent DCL. Four patients were palliated. Seventy of 94 (74%) sustained HVI; 44 of 70 (63%) had colonic injury. Repair or resection with anastomosis was performed in 59 of 67 therapeutically managed HVI patients (88%). Six patients were managed with fecal diversion, and 6 patients were evacuated with discontinuous bowel. Anastomotic leaks occurred in 4 of 56 HVI patients (7%) with known outcomes. Median New Injury Severity Score for DCL patients was 29 (interquartile range: 18-41) versus 19.5 (interquartile range: 12-34) for patients undergoing definitive laparotomy (P = 0.016). Overall mortality was 15 of 94 (16%).
Conclusions: Damage control is now used routinely for battlefield abdominal trauma. In a well-practiced Combat Support Hospital, this strategy is associated with low mortality and infrequent fecal diversion.
