Background:
Mortality from perforated peptic ulcer disease (PUD) remains high, especially in sub-Saharan Africa. We sought to identify predictors of mortality following surgery for perforated PUD.
Methods:
We performed a retrospective study of acute care surgeries at Kamuzu Central Hospital (KCH) in Malawi from 2013 to 2022. Patients undergoing omental patch surgeries were included. Bivariate and multivariate analyses were used to model predictors of mortality.
Results:
A total of 248 patients were included. The mean age was 30 ± 15 years. Ninety percent were male. Mortality rate was 22.2%. Predictors of mortality included age (adjusted odds ratio [AOR] 1.06, 95% confidence interval [CI] 1.03-1.09), shock index (AOR 1.86, 95% CI 1.14-3.03), days to operative intervention (AOR 1.44, 95% CI 1.10-1.88), and presence of complications (AOR 9.65, 95% CI 3.79-24.6).
Conclusions:
Mortality following surgery for perforated PUD remains high in this low-resource environment. In-hospital delay is a significant and modifiable predictor of mortality.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
