Peritoneoscopy in extrahepatic abdominal diseases.

Results of peritoneoscopy performed under local anesthesia were reviewed in 43 consecutive patients with predominantly extrahepatic disease. Patients with previous laparotomy scars and poor general condition were not refused the benefits of this procedure. Diagnostic accuracy was 84%. Histologic diagnosis was achieved in 42% of patients and cholecystocholangiography under peritoneoscopic guidance in two jaundiced patients. Laparotomy was avoided in 65% of patients, and peritoneoscopy correctly assessed local extent of gastric neoplasia in 76% (16/21). Complications were insignificant. Peritoneoscopy under local anesthesia is a quick, accurate, economic, and safe method for evaluating extrahepatic abdominal disease.
