ObjectiveTo summarize the effect of artificial blood vessel replacement in the treatment of complex hepatic alveolar hydatid disease involving retrohepatic inferior vena cava.MethodClinical data of 5 patients with hepatic alveolar hydatid disease involving retrohepatic inferior vena cava, who underwent vena cava replacement operation from June 2018 to August 2019 in our hospital were collected to analyzed.ResultsThe operation was successfully completed in all the 5 patients, and the hepatic hydatid space-occupying lesions were completely removed. Among them, 2 cases underwent extended right hemihepatectomy and caudate lobectomy, the operative time was 7 h and 8 h, the intraoperative blood loss was 600 mL and 400 mL, respectively, and the hospital stay were both 14 d. Three cases underwent autotransplantation surgery, with the operative time of 16 h, 12 h, and 12 h, the intraoperative blood loss was 1 500 mL, 1 500 mL, and 1 000 mL, and the hospital stay were 24, 20, and 19 d, respectively. There was no massive hemorrhage occurred, and 1 case suffered from liver failure (compensatory period), 2 cases suffered form bile leakage, all of which were cured by liver protection, anti infection, and drainage. During the follow-up period, the 5 cases were all in good condition, no relapse or recurrence occurred, and the quality of life was good.ConclusionThe replacement of the infected inferior vena cava by artificial blood vessel is an effective and feasible method for the treatment of hepatic alveolar hydatid disease involving retrohepatic inferior vena cava.
ObjectiveTo discuss the clinical application of two-step hepatectomy for hepatic alveolar echinococcosis which invaded the second and the third porta hepatis.MethodsThe clinical data of 60 patients with hepatic alveolar echinococcosis invaded the second and the third porta hepatis who treated with two-step hepatectomy in West China Hospital of Sichuan University and The People’s Hospital of Ganzi Tibetan Autonomous Prefecture of Sichuan Province from Jan. 2013 to Jun. 2017 were analyzed retrospectively.ResultsSixty patients had underwent radical hepatectomy successfully and no death happened during perioperative period. The average operative time was 309.17 min (150–475 min) and intraoperative blood loss was 586.67 mL (100–3 000 mL). Forty-eight patients blocked the blood flowing into the liver, the average blocking time was 25.85 min (15–50 min); 24 patients suffered red blood cell suspension, the average amount was 3.79 U (2–8 U), and 9 patients were infused with fresh frozen plasma, the average amount was 527.78 mL (350–850 mL). The average of hospital stays was 17.5 days (7–39 days) and average of hospitalization cost was 49 323.43 yuan (28 045.32–61 243.15 yuan). The liver function indicators returned to normal within 7 days after operation. After operation, 3 patients suffered from biliary fistula, 3 patients suffered from pleural effusion, 3 patients suffered from peritoneal effusion, 10 patients suffered from effusion. According to the rank of complication: 10 patients were defined as grade Ⅰ, 3 patients were defined as grade Ⅱ, 6 patients were defined as grade Ⅲa. The average follow-up time of 60 patients was 14.47 months (1–31 months). No recurrence and death occurred during follow-up period.ConclusionThe two-step hepatectomy in treatment of hepatic alveolar echinococcosis invaded the second and the third porta hepatis can avoid the large flucyuations of intraoperative blood pressure and other vital signs, can increase the safety of surgery and reduce the difficulty and risk of surgery.
ObjectiveTo summarize short-term and long-term effects of ex vivo liver resection followed by autotransplantation (Abbreviation: autotransplantation) in treatment of advanced hepatic alveolar echinococcosis (HAE).MethodThe clinical data and follow-up data of 17 patients with advanced HAE who underwent autotransplantation from November 2016 to July 2019 in the Ganzi Tibetan Autonomous Prefecture People’s Hospital were retrospectively analyzed.ResultsThe autotransplantations were performed successfully in the 17 patients with advanced HAE. Ten patients underwent the inferior vena cava (IVC) reconstruction with autologous saphenous veins, 5 patients underwent the artificial revascularization, 1 patient underwent the direct anastomosis of the original IVC, and 1 patient didn’t reconstructed (the retroperitoneal collateral circulation was abundant). The mean liver graft mass was 681.3 g (365–1 350 g) and operation time was 11.5 h (9–16 h). The median anhepatic period was 312 min (175–450 min), blood loss was 2 000 mL(950–4 500 mL), red blood cell suspension transfusion was 6.4 U (1–20 U), and fresh frozen plasma was 1.1 L (0.8–2.0 L). The postoperative hospital stay was 5 to 45 d with an average of 25.6 d. There were 4 patients with the postoperative hepatic enveloping effusion, 1 patient with bile leakage, and 1 patient with bile duct stenosis. All of them were treated and cured, and no death occurred. The follow-up time of 17 patients was 3 to 35 months with an average of 9.5 months, no recurrence of HAE and distant metastasis were observed.ConclusionsIn highlands, autotransplantation in treatment of advanced HAE patients with different IVC reconstruction is satisfactory, but it has a higher risk and is difficult. Choice of intraoperative reconstruction materials, judgment of posterior peritoneal collateral circulation, presence or absence of tension in end-to-end anastomosis of the IVC require precise consideration. At the same time, anticoagulation therapy and complications management are difficult, and it is only suitable for plateau medical center with rich experience.
Objective To summarize the methods, safety, and efficacy of the ex vivo liver resection followed by autotransplantation in the treatment of advanced hepatic alveolar echinococcosis (HAE). Method A retrospective analysis of clinical data and follow-up data in 21 cases who received ex vivo liver resection followed by autotransplantation in the treatment of HAE from February 2014 to December 2016 in West China Hospital was performed. Results All the patients successfully underwent ex vivo liver resection followed by autotransplantation and no death happened during operation. The median weight of remnant liver was 701.4 g (360–1 300 g), the average operation time were 13.6 h (9.4–19.5 h), the anhepatic phase time were 180–455 min with median of 314 min. The average of intraoperative blood loss were 2 379 mL (1 200–6 000 mL). The average of patients entered red blood cell suspension were 10.6 u (0–39.5 u), the average of fresh frozen plasma were 1 377 mL (0–6 050 mL) , of which 7 patients received autologous blood transfusion, with average of 1 578 mL (500–3 700 mL). The average of postoperative hospital stay were 23.5 days (4–51 days). Postoperative complications occurred in 12 patients during hospitalization, and 4 cases of postoperative complications were in grade Clavien-Dindo Ⅲ or above, 2 cases of grade Ⅴ (died). During the follow-up period, 19 patients were followed for a median of 16.2 months (3–38 months), no HAE recurrence or metastasis was found, only 1 patient were lost follow-up after surgery for 12 months. Massive ascites and hyponatremia were found in 1 patient who was diagnosis as left hepatic vein stenosis at the end of the 3 months after operation. The patient was cured after interventional treatment of hepatic vein stent implantation and angioplasty. Conclusions The ex vivo liver resection followed by autotransplantation provides radical treatment for patients with advanced HAE, but the surgery is difficult and has high risk of postoperative complications. The detailed preoperative evaluation, intraoperative pipeline reconstruction reasonably, and fine postoperative management can improve the patient’s survival, and reduce the rate of complications.
Objective To discuss the clinical application of two-stage hepatectomy for multiple and huge hepatic alveolar echinococcosis. Methods The clinical data of 7 patients with multiple hepatic alveolar echinococcosis treated with two-staged hepatectomy in West China Hospital of Sichuan University and The people's Hospital of Ganzi Tibetan Autonomous Prefecture of Sichuan Province from August, 2013 to June, 2016 were analyzed retrospectively. The preoperative diagnose was definite according to CT and (or) MRI, serological and life in the epidemic area. The patients, which the future liver remnant was less than 30% according to CT, received two-staged hepatectomy. Epigastric enhancement CT, liver function and blood routine examination were reviewed monthly after the first surgery, the second surgery was operated after 3 monthes, epigastric ultrasound, enhancement CT or MRI, liver function, blood routine examination and serological were adopted in 1, 6, and 12 months and each year after the second operation. Results The liver function was normal in 7 days after two operations and no complications after the first suegery, one patient developd with biliary fistula after the second surgery, no recurrence or death occurred during the followed-up period. Conclusion The two-stage hepatectomy can be operated in multiple and huge alveolar echinococcosis to reduce surgery risk and cost, shorten hospital stays and improve quality of life.
