  • Value of Treatment for Hepatolithiasis by Using c-myc shRNA in Chronic Proliferative Cholangitis

    Objective To determine whether local delivery of c-myc shRNA could inhibit hyperplasia and lithogenic potentiality in a rat model of chronic proliferative cholangitis (CPC) via specific blockade of the c-myc expression. Methods The CPC animal model (CPC group) was established via retrograde insertion of a 5-0 nylon thread into the common bile duct through Vater’s papilla. Three kinds of c-myc shRNAs were then respectively injected in c-myc shRNA group, which were included shRNA-1, shRNA-2, and shRNA-3, respectively. Negative control group and sham operation group were established for comparison. Subsequently, histopathological changes of bile duct wall were observed by HE, Massion, and PAS/AB staining; c-myc protein was detected by immunohistochemistry method; 5-bromodeoxyuridine (BrdU) protein was tested by immumofluorescence method; c-myc,  Mucin 3, and Procollagen Ⅰ mRNAs were detected by real time PCR; Ki-67 protein was determined by Western blot; Activity of β-glucuronidase was measured by modified Fisherman method. Results  ①Compared with the CPC and negative control groups, biliary tract mucosa epithelium (HE staining), submucosal acid mucinous gland (mid-blue staining, PAS/AB staining), and degree of over-hyperplasia of collagen fiber in bile duct wall (blue staining, Massion staining) were weaker in the c-myc shRNA group. ②The expressions of c-myc mRNA, Mucin 3 mRNA, Procollagen Ⅰ mRNA, Ki-67 protein, and β-G activity in the c-myc shRNA group were lower than those of the CPC and negative control groups (Plt;0.05), but higher than those of the sham operation group (Plt;0.05). Conclusion c-myc shRNA treatment could effectively inhibit the hyperplastic behavior and lithogenic potential of CPC, which might help to prevent the biliary restenosis and stone recurrence.

  • Analysis on Surgical Treatment for Hepatolithiasis with Recurrence and Residue

    目的探讨肝内胆管残留或再发结石的外科治疗方法及疗效。方法对1998年7月至2004年10月期间收治的96例肝内胆管残留或再发结石患者的资料进行回顾性分析。结果行肝叶切除44例; 肝段切除11例; 肝门部胆管切开并肝膈面实质切开联合取石引流术11例,其中附加胆肠大口径Roux-en-Y吻合术10例; 肝门部胆管整形、肝管空肠大口径Roux-en-Y吻合术30例。全组术中均采用胆道镜检查取石,术后经T管窦道检查取石6例。术后随访1~6年,76例(79.2%)无结石残留或再发。结论据结石部位及肝脏病变合理选择手术方法是有效治疗肝内胆管残留或再发结石的较好方法。

  • Preliminary Experience with Indications for Liver Transplantation for Hepatolithiasis

    Objective To explore the indications for liver transplantation among patients with hepatolithiasis. Methods Data from 1431 consecutive patients with hepatolithiasis who underwent surgical treatment from January 2000 to December 2006 were retrospectively collected for analysis. Surgical procedures included T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones, hepatectomy, cholangiojejunostomy, and liver transplantation. Results Nine hundred and sixty-one patients who had a stone located in the left or right intrahepatic duct underwent hepatectomy or T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones. The rate of residual stones was 7.5% (72/961). Four hundred and seventy patients who had a stone located in the bilateral intrahepatic ducts underwent surgical procedures other than liver transplantation; the rate of residual stones was 21.7% (102/470). Only 15 patients with hepatolithiasis underwent liver transplantation; they all survived. According to the degree of biliary cirrhosis, recipients were divided into 2 groups: a group with biliary decompensated cirrhosis (n=7), or group with biliary compensated cirrhosis or noncirrhosis group (n=8). There were significant differences in operative times, transfusion volumes and blood losses between 2 groups (P<0.05). In the first group, 6 of 7 patients experienced surgical complications, and in the second, 8 recipients recovered smoothly with no complications. Health status, disability and psychological wellness of all recipients (n=15) were significantly improved in 1 year after transplantation as compared with pretransplantation (P<0.05). Conclusion Liver transplantation is a possible method to address hepatolithiasis and secondary decompensated biliary cirrhosis or difficult to remove, diffusely distributed intrahepatic duct stones unavailable by hepatectomy, cholangiojejunostomy, and choledochoscopy.

  • Application of ultrasound-guided percutaneous transhepatic cholangioscopy in treatment of complicated hepatolithiasis

    Objective To investigate feasibility and curative effect of ultrasound-guided percutaneous transhepatic cholangioscopy in treatment of complicated hepatolithiasis. Methods The data of 42 patients with complicated hepatolithiasis from June 2012 to June 2017 in the Hepatobiliary Surgery, the First Affiliated Hospital of Xi’an Jiaotong University were retrospectively analyzed. All the patients were treated with ultrasound-guided percutaneous transhepatic cholangioscopy, including the first stage of dilation and drainage and the second stage choledochoscopy. Results The operations of the 42 patients were successfully performed. No case was converted to the conventional laparotomy. The puncture sites of 10 cases were at the right intrahepatic bile duct, 25 cases were at the left intrahepatic bile duct, and 7 cases were at the bilateral intrahepatic bile duct. The residual stones were removed by two stage choledochoscopy in the 31 patients, 11 patients had the residual stones. After the first stage, there were 4 cases of the bile duct hemorrhage, 8 cases of the cholangitis, 1 case of the pleural effusion and 1 case of the infection, 2 cases of the postoperative drainage tube shedding. After the second stage, there were 3 cases of the cholangitis and 3 cases of the postoperative drainage tube shedding. The stones of the 10/31 patients with stone removal occurred and the diseases of 9/11 patients with stone residual were stable during the following-up of (18.6±7.8) months. Conclusion Ultrasound-guided percutaneous transhepatic cholangioscopy including the first stage of dilation and drainage plus the second stage choledochoscopy is safe and effective in treatment of complex intrahepatic bile duct stones, it is an effective supplement to traditional surgery.
