BackgroundMain concern during the practice of selective non-operative management (SNOM) for abdominal stab wounds (SW) and gunshot wounds (GSW) is the potential for harm in patients who fail SNOM and receive a delayed laparotomy (DL). The aim of this study is to determine whether such patients suffer adverse sequelae because of delays in diagnosis and treatment when managed under a structured SNOM protocol.Methods190 patients underwent laparotomy after an abdominal GSW or SW (5/04-10/12). Patients taken to operation within 120 min of admission were included in the early laparotomy (EL) group (n =153, 80.5 %) and the remaining in the DL group (n =37, 19.5 %). Outcomes included mortality, hospital stay, and postoperative complications.ResultsThe median time from hospital arrival to operation was 43 min (range: 17-119) for EL patients and 249 min (range: 122-1,545) for DL patients. The average number and type of injuries were similar among the groups. Mortality and negative laparotomy were observed only in the EL group. There was no significant difference in the hospital stay between the groups. The overall complications were higher in the EL group (44.4 vs. 24.3 %, p =0.026). DL was independently associated with a lower likelihood for complications (OR 0.39, 95 % CI 0.16-0.98, p =0.045). Individual review of all DL patients did not reveal an incident in which complications could be directly attributed to the delay.ConclusionsIn a structured protocol, patients who fail SNOM and require an operation are recognized and treated promptly. The delay in operation does not cause unnecessary morbidity or mortality.
