title: Unusual causes of acute abdomen in a Nigerian hospital.
abstract: Acute abdomen is the most common abdominal emergency associated with high morbidity and mortality in General surgical practice. Over a 7-year period, a study of unusual causes of acute abdomen was undertaken, with the aim of identifying these causes and outcome of operative management. Eleven cases were identified accounting for 4% of cases of acute abdomen seen during the period of the study. Four cases of liver diseases (33.3%) comprising 2 patients (16.7%) with ruptured primary liver cell carcinoma, 1 (one) case each of haemoperitoneum due to ruptured liver haemangioma and haemorrhagic disorders from liver cirrhosis. One patient had acute leukaemia with massive haemoperitoneum and acute abdomen. Five (45.5%) had gastrointestinal perforations; 1 patient (9%) each had multiple jejunal perforations, perforation of stomal ulcer at gastrojejunostomy site, perforation of gastric cancer; perforated carcinoid tumour of sigmoid colon and idiopathic perforation of the caecum. There was also a case of caecal volvulus. Mortality was 7 patients (63.6%). All patients with liver pathology and acute leukaemia died. The cases of malignant tumour perforation were well and alive 4-6 years after the operation.
  
  
  CONCLUSIONS
  Operation could have been avoided in 45.5% of these cases if the appropriate investigations, had been available and carried out.
