Selective nonoperative management of abdominal gunshot wounds with isolated solid organ injury.

Objective: To review selective nonoperative management (SNOM) of gunshot wound (GSW) patients with isolated abdominal solid organ injury.

Methods: Patients who sustained isolated solid organ injury secondary to GSW from 2003 to 2014 were studied. The use of SNOM over time was analyzed, and comparisons of initial SNOM and operative management (OM) groups were performed.
