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.
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.
Objective To investigate the recurrence of intrahepatic bile duct stones and study the relations to the primary intrahepatic stones.Methods One hundred and twenty nine patients who experienced complete lithotomy were followed up for 2-10 years. Results Thirty five cases had the recurrence of intrahepatic stones at 49 sites (27.13%). The recurrent stones were found at following sites: 13 at left duct, 12 right duct , 8 left medial segment, 6 right anterior segment, 4 right posterior segment, 3 left lateral segment, 3 caudate. Nine cases were asymptomic, 16 cases had slight symptoms and 10 cases suffered from the serious attacks of stones. The time of recurrence was from 2 to 9 years (5.49±2.25 years) after surgery. The recurrent rate was 27.13% in our group. Conclusion The recurrence of intrahepatic stones also developed at several sites in the liver. The recurrence of intrahepatic stones had a tendency to develop at the primary sites. The recurrence of intrahepatic stones may be asymptomic and most patients suffered from slight attack. Liver resection is the best way to prevent the recurrence from intrahepatic stones.

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.
ObjectiveTo investigate the option of biliary drainage for surgical management of hepatolithias. MethodsThe clinical data of 146 patients with hepatolithiasis, who were admitted to the First Affiliated Hospital of Anhui Medical University from March 2006 to June 2014, was analyzed retrospectively.These patients were divided into biliary enteric drainage group and T tube drainage group according to the function of sphincter of Oddis.The intra-operative related data, postoperative complications, and long-term efficacy were compared between two groups. Results①The two groups were comparable in terms of gender, age, body weight, preoperative liver function, preoperative symp-toms and signs, preoperative biochemical index, calculus distribution, preoperative complications (P > 0.05).②There were no significant differences of the hepatolobectomy rate, intraoperative blood loss, intraoperative blood transfusion, times and time of hepatic portal occlusion, bile culture positive rate, hospital stay and hospitalization expenses between two groups (P > 0.05).But the operation time of the biliary enteric drainage group was significantly longer than that of the T tube drainage group (P < 0.001).③The total complications rate and specific complication rate were not signifi-cantly different between two groups (P > 0.05).④The stone instant clearance rate of the biliary enteric drainage group was significantly higher than that of the T tube drainage group (P=0.031).But the stone final clearance rate was not significantly different between two groups (P=0.841).⑤The postoperative quality of life was not significantly different between two groups (Excellent and good:P=0.560;Poor:P=0.560).The rates of stone residual, recurrence, mortality and canceration were not significantly different between two groups (P > 0.05). ConclusionThe biliary drainage for surgical management of hepatolithias is selected according to the function of sphincter of Oddi.Biliary enteric drainage and Roux-en-Y anastomosis are firstly selected for patients with the loss of function of sphincter of Oddi.
Objective To study the etiology of primary intrahepatic stones. MethodsThe literatures in the recent years on the etiology of intrahepatic stone were revieved. Results The formation of intrahepatic stone mainly caused by bacteria infection, parasitic infestation, bile stasis, congenital anatomic abnormalities and immunoreaction of bile tract. Further investigation found that metabolic, low protein diet, environment and ethnic factors and gene mutation were considered to play important roles in the formation of the intrahepatic stone. Conclusion The formation of intrahepatic stone is complex and are result of multiple factors. It closely related to the infection and stasis of the bile duct.
Objective To explore risk factors and treatment strategies of liver resection surface infection following laparoscopic hepatolithiectomy for patient with complicated intrahepatic bile duct stones. Methods The clinical data of 45 patients with complicated intrahepatic bile duct stone underwent laparoscopic hepatectomy from January 2014 to April 2017 in this hospital were analyzed. The liver resection surface infection rate, pathogenic bacteria distribution, factors of operation, antibiotic use time, volume of drainage, and drainage tube placement time were analyzed. Results A total of 13 cases of liver resection surface infection occurred following the laparoscopic hepatolithiectomy in the 45 cases, the infection rate was 28.89%. Totally 24 strains of pathogens were isolated from the infected patients, including 9 strains of gram-positive bacteria and 15 strains of gram-negative bacteria. The mainly postoperative complications included 16 cases of the biliary leakage, 5 cases of the effusion and empyema, the average drainage volume was about 200 mL after the surgery. The double pipes were placed in the 10 patients in the operation. The drainage tubes were placed in the 23 patients under the ultrasound or CT intervention after the surgery, the average time of drainage tube placement was 8 d. The results of univariate analysis showed that the past biliary surgery history, combined with liver cirrhosis, double pipe drainage, operation time, and postoperative biliary leakage were associated with the liver section surface infection following the laparoscopic hepatolithiectomy (P<0.050). The results of multivariate analysis identified that the past biliary surgery history and postoperative biliary leakage were the risk factors (P<0.050), while the double pipe drainage was the protective factor (P<0.050) for liver resection surface infection following the laparoscopic hepatolithiectomy. Conclusions Prophylactic treatment such as perfect preoperative management and careful intraoperation should be taken for risk factors of liver section surface infection following laparoscopic hepatolithiectomy. Actively effective treatment strategies should be given if postoperative liver section surface infection existence.
