Objective: To find out frequency, etiology and duration of illness leading to secondary bacterial peritonitis in surgical practice. Study design: Descriptive case series. Place & Duration of study: Department of Surgery Civil Hospital / Dow University of Health Sciences & SMBB Medical College Lyari Karachi, from February 2010 to January 2015. Methodology: All patients above 18 years of age diagnosed as secondary bacterial peritonitis admitted in emergency and underwent exploratory laparotomy were included. All patients with suspected primary bacterial peritonitis, chronic renal failure, nephrotic syndrome, congestive cardiac failure or chronic liver disease, were excluded. The data was collected for demography, clinical features, investigations, duration of illness, and exploratory laparotomy findings. Results: A total of 151 patients underwent exploratory laparotomy. Typhoid gut perforation was the commonest etiology (n= 65 - 43.04%), followed by peptic ulcer perforation (n=47 - 31.11%) and tuberculosis perforation (n=39 - 25.8%). The average duration of illness leading to secondary bacterial peritonitis was 11.6 days in typhoid fever, 20.6 days for duodenal ulcer and 58.34 days in tuberculosis. Conclusions: Secondary bacterial peritonitis was one of the commonest surgical emergencies. Typhoid fever was the commonest cause.
