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 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.
In 1983-1994,748 cases hepatocholelithiasis had been treated in our department, in which 372 patients underwent hepatectomy and 43 patients underwent hepatectomy of the quadrate lobe. Hepatectomy of the quadrate lobe has been performed to treat all kinds of hepatocholelithiasis, it is easy to expose 1 or 2 degree branch of biliary tree, incise the hepatobiliary stricture and perform hepatocholangiojejunostomy in the hepatic hilum.
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 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.
