[Simultaneous combined radical surgery for hepatic and renal alveolar echinococcosis: an analysis of 10 clinical cases].

Objective: To examine the feasibility, safety and efficacy of simultaneous combined radical surgery for hepatic and renal alveolar echinococcosis (AE). Methods: Clinical dates of consecutive 10 hepatic and renal AE patients who accepted surgical treatment in the First Affiliated Hospital of Xinjiang Medical University during April 2013 to September 2019 were analyzed retrospectively. There were 8 males and 2 females, aged (42.5±10.3) years (range: 27 to 52 years). Seven of them had previously palliative surgical treatment with poor compliance to post-operative medication. All of the patients had hepatic-renal combined AE lesions, and two of them had left lateral and left renal lesions for each, which sized for (726.4±576.1)cm3 (range: 117.0 to 1 998.0 cm3). Extra-hepatic or renal lesions infiltrated to right diaphragm, inferior vena cava, right adrenal gland, abdominal wall, right psoas muscle, duodenum wall and right pulmonary lobe (respectively were 7, 7, 6, 2, 1, 1, 2 cases). Surgery were performed mainly with simultaneous combined surgery and vascular reconstruction techniques for this series. Hemi-hepatectomy or extended right lobectomy was applied in 8 patients, while 2 other patients received ex vivo liver resection and autotransplantation, additionally, one patient had partial hepatectomy for left lateral lobular lesion. Total right nephrectomy, partial right nephrectomy and partial left nephrectomy were respectively performed on 7, 3 and 1 patient(s). Additionally, extra-hepatic or renal lesions were eradicated followed by relevant repairments or reconstructions. Results: Surgeries went well and there was no intra-or post-operative liver or renal dysfunction occurred. During recovery period, 3 cases experienced with hydrothorax and managed well after drainage and supportive treatment, and one patient developed peri-renal urinary leakage and cured by "J" catheter. The subjects were followed-up for 6 to 81 months (median: 21 months), no death, organ dysfunction, chronic or acute kidney diseases occurred. One case encountered with abdominal hernia at post-operative 7th month and was successfully managed with laparoscopic repair with artificial mesh. No disease recurrence in all patients, which reached clinical cure at last. Conclusion: When complied strictly to indications, simultaneous combined radical surgery could be a feasible, safe and efficient approach for patients with hepatic and renal AE, which is primary or relapsed from previous hepatic AE surgery or interventional therapies as well as neighboring organ AE invasions.
