Tuberculous peritonitis: the value of laparoscopy.

The laparoscopic and pathological diagnoses of 43 patients who underwent abdominal laparoscopy for various indications are presented. Major indications for the laparoscopy included hepatomegaly in 32 patients, ascites in 28, and pyrexia of unknown origin (PUO) in 18 patients. A combination of two or more of these indications was a more common feature. The most frequently encountered laparoscopic diagnoses were tuberculosis and chronic liver disease (16 patients each), followed by cancer (9 patients). However, on pathological examination of peritoneal or liver biopsy tissue and on follow-up, tuberculosis was confirmed in 12 patients, chronic liver disease in 14 patients and hepatocellular carcinoma in 11 patients. No complications were encountered during the laparoscopy. Our findings indicate that abdominal laparoscopy is a safe, quick and inexpensive diagnostic tool, particularly when appropriate and adequate tissue is taken for pathological examination. In such instances, laparoscopy would save an unnecessary laparotomy, especially where tuberculosis and cancer are considered in the differential diagnosis.
