1. 247 cases clinically suspected of primary cancer of the liver were peritoneoscoped during the period of 1970-1978. 2. Peritoneoscopy alone made a correct diagnosis of primary cancer of the liver in 93%. It made an error in diagnosis in 7%. It missed the diagnosis of primary cancer of the liver in 2%. If combined with guided direct vision liver biopsy, the accuracy is almost 100%. 3. It is safe procedure and is an accurate way of ruling out the diagnosis of clinically suspected primary cancer of the liver.
