The role of total pericystectomy in hepatic hydatidosis

Abstract

Between 1977 and 1995, 495 patients were operated on for hepatic hydatidosis. Total pericystectomy was performed in 26 patients (closed technique in 21 and open technique in 5). Twenty-one patients had single cysts and 5 had two cysts. The median cyst diameter was 8cm (range; 3–20cm). The requirements for total pericystectomy were: (1) the cyst(s) should be located away from the hepatic veins, large bile ducts, or major branches of the portal vein and hepatic artery and (2) the patient should be fit to undergo a major operation. There was no procedure-related morbidity. One patient developed a biliary fistula that closed after endoscopic sphincterotomy. The median hospital stay was 7 days (range; 3–22 days). The median follow up was 24 months (range; 9–114 months). There was disease recurrence in a non-adjacent segment in 1 patient at 4 years. Pericystectomy is a potentially dangerous operation, but it avoids problems with cavity management and has low rates of biliary fistula, spillage, and recurrence. Its success stems primarily from careful patient selection.
