Abstract
BACKGROUND: Despite increases in surgical capacity in Malawi, minimal data exist on postoperative complications. Identifying surgical management gaps and targeting quality improvement requires detailed, longitudinal complications, and outcome data that assess surgical safety and efficacy. METHODS: We conducted a 6-mo prospective, observational study of patients >12 y after laparotomy at a tertiary hospital in Lilongwe, Malawi. Outcomes included postoperative complications and mortality. The seniormost rounding physician determined complication diagnoses. Bivariate and Poisson regression analyses identified predictors of mortality. RESULTS: Only patients undergoing emergent laparotomy (77.8%) died before discharge, so analysis excluded elective cases. Of 189 patients included, the median age was 33.5 y (IQR 22-50.5), 22 (12.2%) had prior abdominal surgery, and 11 (12.1%) were human immunodeficiency virus-positive. Gastrointestinal perforation was the most common diagnosis (35.5%). The most common procedures were primary gastrointestinal repair (24.9%), diverting ostomy (21.2%), and bowel resection with anastomosis (16.4%). Overall postoperative mortality was 14.8%. Intra-abdominal complication occurred in 17 (9.0%) patients, of whom 8 (47.1%) died. Older age (RR 1.05, 95% CI 1.02-1.08, P < 0.001) and intra-abdominal complication (RR 2.88, 95% CI 1.28-6.46, P = 0.01) increased the relative risk of mortality. Preoperative diagnosis, surgical intervention type, and symptom-to-surgery time did not increase the relative risk of mortality. CONCLUSIONS: The incidence of complications and mortality after laparotomy at a large referral hospital in Malawi is high. Older age and intra-abdominal complications increase the risk of death. Strategies to improve operative mortality in Malawi should prioritize postoperative surveillance and management and continued outcomes reporting.
