Clinico-pathological pattern and early post-operative complications of gastro-duodenal perforations at Mulago Hospital Kampala- a prospective cohort study

Background:  Gastro-Duodenal Perforations are one of the commonest causes of mortality and morbidity in conditions that require emergency surgery. The main objective of this study was to determine the clinico-pathological pattern and evaluate factors for early post operative complications of Gastro-duodenal perforations in Mulago.  Methods:  This was a prospective cohort study of patients with gastro-duodenal perforations managed by simple repair between September 2014 and April 2015 in Mulago was studied. Primary/ secondary outcomes were mortality and complications respectively. Data was managed using stata-12 and multivariate analysis using log-binomial regression model.  Results:  A total of 65 patients were operated for Gastro-duodenal perforations in the study period. 86.2% were male (M: F 6.2:1). Median age was 35 years (range 16- 80 years). 93.9% had gastric perforations. Clinical diagnosis was predicted in 89.3%.  H. pylori was present in 7.9%. Mortality was 18.5% and complications developed in 58.5%. Age above 35 and presence of   co morbidity predicted mortality (CI 1.22- 21.12, p= 0.009) (CI 1.26- 8.82, p= 0.024) and early post-operative complications (CI 1.03- 2.44, p= 0.031) (CI 1.23- 2.44, p= 0.011) respectively.  Conclusion:  Gastroduodenal perforations remain a common surgical emergency in Mulago hospital affecting mainly young men below 35 years. Majority are gastric perforations. Mortality and early post-operative complications are high, and increase with age and presence of co morbidity.
