BACKGROUND: Damage control surgery (DCS) is a widely used approach in trauma. An open abdomen carries complications, increased morbidity and mortality. This study aims to quantify the mortality rate, determine contributory factors and factors influencing the decision to perform DCS and assess morbidity in patients undergoing open abdomen METHODS: A retrospective review was conducted on 205 patients in Charlotte Maxeke Johannesburg Academic Hospital Trauma Unit. The mortality rate was evaluated over a 24-hour, 7-day and 28-day period. Data were collected by a data collection sheet from 1 January 2016 to 31 December 2018 RESULTS: Of the 205 patients, 193 were male and the median age was 34.34 years. Penetrating trauma was the most predominant mechanism of injury in 162 (79%), with gunshot injuries seen in the majority (130/162). The mortality rate was 55/205 (26.8%) for open abdomen patients, 19/55 (34.5%) within the first 24 hours, 22/55 (40%) in the 24-hours to 7-days period, and 14/55 (25.4%) in the 8-day to 28-day period. Statistically significant factors contributing to mortality were haemodynamic instability, hypothermia, coagulopathy, massive transfusion, vasopressors, and significant associated injuries. Morbidities were entero-atmospheric fistula (EAF) in 7.3% (Clavien-Dindo grade Ilia), surgical site infection in 45.3% (Clavien-Dindo grade I) and ventral hernia in 10.24% (Clavien-Dindo grade IIIb CONCLUSION: Most open abdomens were performed in males, with gunshot injuries being the most common mechanism. The majority of mortalities were within the 24-hours to 7-days period. The most common morbidity associated with an open abdomen was surgical site infection
