Methodology: All the patients with peritonitis who presented through emergency department were included. Risk factors like anemia, diabetes mellitus, hypertension, obesity, respiratory infection, frequency of burst abdomen and causes like typhoid ileal perforation, tuberculous perforation, ruptured appendix, duodenal ulcer perforation, ruptured liver abscess were recorded on pre designed forms. 

Result: The age of the 90 patients who presented with acute peritonitis was from 13 years to 65 years with the mean age of 39±5 year. There were 60 (66.67%) male and 30 (33.33%) female patients.

Causes of peritonitis were ruptured liver abscess (n=4 - 4.44%), colonic perforation (n=2 - 2.22%), intestinal tuberculous ileal perforation (n=9 - 10%), duodenal ulcer perforation (n=19 - 21.11%), ruptured appendix (n=17 - 18.89%) and typhoid ileal perforation (n=38 - 43.33%). The risk factors in burst abdomen were hypoalbuminemia (66.67%), postoperative respiratory tract infection/cough (41.67%), intra-abdominal collection (33.33%), anemia (8.3%), paralytic ileus (16.67%), obesity/BMI>30 (8.3%).
