ObjectiveTo evaluate and discuss the various surgical methods for hepatic echinococcosis. MethodsFour hundred and two patients with hepatic echinococcosis were treated in West China Hospital of Sichuan University from 2009 to 2014 and 271 of them were undergone surgical treatment. The cystic echinococcosis was in 195 patients, including 80 cases performed classic endocystectomy or subtotal cystectomy, 109 performed total cystectomy or hepatectomy, 6 cases performed palliative surgery. The alveolar echinococcosis was in 76 patients, including 7 cases performed palliative surgery, 54 cases performed hepatectomy, 12 cases performed liver allotransplantation, and 3 cases performed liver autotransplantation. Results①The draining time, the rate of postoperative complications, and the recurrence was (18.6±2.7) d, 21.2% (17/80), and 15.0%(12/80) respectively in the cases of cystic echinococcosis underwent classic endocystectomy or subtotal cystectomy, which were significantly higher than those cases of cystic echinococcosis underwent total cystectomy or hepatectomy〔(5.4±0.6) d, 7.3% (8/109), and 0.9% (1/109), respectively, P < 0.05〕.②The draining time and the recurrence was (5.9±0.7) d and 1.8% (1/54) respectively in the cases of alveolar echinococcosis underwent hepatectomy, which were significantly lower than those in the cases of alveolar echinococcosis took palliative surgery〔(9.7±1.4) d and 57.1% (4/7), respectively, P < 0.01〕. The 12 patients underwent liver transplantation were complete rehabilitation, while the rest 3 were death. Conclusions①Total cystectomy or hepatectomy should be the first choice for cystic echinococcosis; Palliative treatment could improve the symptoms of unresectable patients with cystic echinococcosis.②Hepatectomy should be the first choice for alveolar echinococcosis, palliative surgery could only be used to alleviate symptoms and physical signs, delay the progression of this disease.③Liver transplantation might be an alternative for advanced hepatic echinococcosis.
ObjectiveTo discuss various surgical methods for hepatic alveolar echinococcosis. MethodsThe clinical data of 98 patients with hepatic alveolar echinococcosis treated in West China Hospital of Sichuan University from 2004 to 2015 were analyzed retrospectively. Palliative surgeries were performed in 9 cases, radical hepatectomies were performed in 69 cases, liver transplantations were performed in 20 cases, in which 12 cases were performed by liver allotransplantation, and 8 cases were performed by liver autotransplantation. ResultsThere was no death case during perioperative period. The rate of postoperative complications of the radical hepatectomy (11.6%, 8/69) was significantly lower than that of the palliative surgery (44.4%, 4/9), which had statistically significant difference (P<0.05). The followup time was from 4 months to 6 years, the average time was 36 months. The postoperative recurrence rate in the radical hepatectomy (1.4%, 1/69) was significantly lower than that in the palliative surgery (55.6%, 5/9), which had statistically significant difference (P<0.05). During follow-up period, the mortality of the palliative surgery (33.33%, 3/9) was also significantly higher than that of the radical hepatectomy (0, 0/69), which had statistically significant difference (P<0.05). Four patients underwent liver transplantation were death within 3 months (20.0%). ConclusionsRadical hepatectomy should be the first choice for alveolar echinococcosis. In this research, although the rates of postoperative complications and recurrence in palliative surgery are higher than those in radical hepatectomy, palliative surgery, for the patients who had lose the opportunity to perform radical hepatectomy, could be used to alleviate symptoms and physical signs, improve quality of life, delay progression of this disease. Although risk of liver transplantation is high, this might be an alternative for advanced hepatic alveolar echinococcosis.
