Radical and nonradical hepatic resection for alveolar echinococcosis: report of 18 cases.
The authors report their experience with 18 patients who underwent liver resection for alveolar echinococcosis of the liver from June, 1982 to January, 1989. Preparation for surgery included transhepatic biliary external-internal drainage in order to alleviate jaundice in 8 cases and catheterization of infected necrotic cavities in 7 cases. Resection was radical in 9 patients who underwent either right lobectomy (5 cases) or right trisegmentectomy (4 cases) with "en bloc" extension to the bifurcation of the hepatic ducts in 3 cases. Resection was nonradical in another group of 9 patients who had either atypical right hepatectomy (6 cases) or atypical left hepatectomy (3 cases). All patients were submitted to a periodic follow-up. The 9 patients treated by radical resection are alive and symptom-free and appear to be disease-free at radiologic imaging, except for 1 patient who had a small area of parasitic recurrence on computed tomography scan 4 years after operation. Among the 9 patients treated by palliative resection, 3 patients died during the follow-up period, the cause of the death having been related to the disease in 2 cases and nonrelated in 1 case. The 6 surviving patients had no noticeable growth of the parasitic mass during the period of follow-up. When feasible, radical liver resection is the best form of therapy. When massive parasitic invasion of both lobes of the liver and the porta hepatis and vena cava precludes radical hepatectomy, palliative resection associated with percutaneous procedures has to be considered before embarking on orthotopic liver transplantation.
