Four hundred and eighty two paients suffering from intrahepatic bile duct stone undergoing lobectomy and segmental resection (from 1975 to 1994,9) has reported. 63% of the patient in this group underwent 1-5 operations, including different types of biliary-intestinal anastomosis (21.6%). 482 cases underwent different types of hepatectomy, including left lateral-lobetomy 321 cases (66.6%),left hemihepatectomy 80 cases(16.6%), right hemihepatectomy 19 cases (3.9%), and multiple segmental resections 39 cases (8.1%, including Ⅴ+Ⅷ 11 cases, Ⅵ+Ⅶ 28 cases). Other type hepatectomy combined with guadrate lobectomy 20 cases (4.1%). Postoperative complication rate was 10.2%, including diliary fistula. hemobilia and subdiaphragmatic and resectional surface infectioin, 85% of the patients were followed up with an excellent result of 88%. The authors emphsize that hepatic lobectomy nad segmental resection is the core of treatment and selection of operative methods depends on clinical-patholigic types of the disease.
【Abstract】ObjectiveTo investigate the anatomic feature and special clinical manifestations of variant right intrahepatic bile duct draining into left hepatic bile duct near the umbilical portion. MethodsVariant right intrahepatic bile ducts joining into left hepatic bile ducts near the umbilical portions were identified through cholangiograms in 52 patients, who were included in this study. Their history, clinical process and operations were reviewed. ResultsThere were total 38 cases of intrahepatic gallstone in this group. High incidence of intrahepatic calculi was found in variant right intrahepatic bile ducts （23/38 cases, 60.52%） and left hepatic ducts （33/38 cases, 86.84%）. Most of these cases were accompanied with dilatation and stricture of bile ducts in these area. The gallstones in the variant right intrahepatic bile ducts were not detected in 8 cases (8/23) and the rate of residual gallstone was as high as 86.95%(20/23). Injury of variant right intrahepatic bile duct took place when left hepatectomy was performed in one case. ConclusionGallstone is very likely to be formed in the variant right intrahepatic bile duct due to derangement of bile hydrokinetics and compression of blood vessel. Special attention should be paid to the diagnosis and operation of this abnormity.
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.
ObjectiveTo investigate the expression of proapoptosis gene bad in intrahepatic cholangiocarcinoma (ICC) and its relationship to differentiation of the tumor.MethodsThe immunohistochemistry technique by Dako Envision system and rabbit antihuman bad polyclonal antibodies were adopted. The expression of bad was detected in 48 cases of ICC and 25 cases of control tissues.ResultsBad immunoreactivity in 48 cases of ICC was higher than that of bile duct epithelium in 25 cases of control tissues. And contrasted with 21 cases of well differentiated ICC, bad immunoreactivity was higher in 27 cases of middle and poor differentiated ICC.ConclusionThe expression of bad gene may be related to the differentiation of ICC.
Objective To discuss the effective surgical treatment of intrahepatic lithiasis combined with high hepatic duct strictures. MethodsTwo hundreds and sixteen cases of intrahepatic lithiasis and high hepatic duct strictures treated in this hospital from January 1993 to October 2002 were analysed retrospectively.ResultsOne hundred and eightythree cases underwent different selective operation by selected time; 33 cases complicated with acute obstructive suppurative cholangitis underwent emergency were performed single biliary drainage, in which 30 cases were reoperated. The operative procedure were: hepatic lobectomy,high cholangiotomy and plastic repair,exposure of hepatic duct of the 2nd and the 3rd order,and plastic repair with own patch and choledochojejunostomy.Two hundreds and six cases were cured,the curative rate was 95.4%; 8 cases improved (3.7%), and 2 cases died (0.9%).Conclusion The best effective surgical treatment of intrahpatic lithiasis is hepatic lobectomy. Exposure of hepatic duct of the 2nd and the 3rd order is a satisfactory to release the hepatic duct strictures and to clear the intrahepatic lithiasis. For patients with normal extrahepatic bile duct and Oddi’s function, plastic repair of bile duct with own patch is possible to keep the normal form and function. Cholangioscopy may play an important role in the treatment of intrahepatic tract lithiasis during operation.
Objective To investigate the roles of NF-κB and EGFR in hepatolithiasis associated with intrahepatic cholangiocarcinoma. Methods Ninety cases of liver tissue specimens from hepatectomies performed in the 2nd Affiliated Hospital of Sun Yat-sen University between August 1989 and June 2009 were enrolled in the study. Among them, 33 cases of hepatolithiasis associated with intrahepatic cholangiocarcinoma were considered as observing group, 32 cases of hepatolithiasis as control group, and 25 cases of normal bile duct tissues as normal control group. The SP method of immunohistochemical staining was applied to detect the expressions of NF-κB and EGFR in intrahepatic biliary ducts epithelial cells, and their relations with clinicopathologic factors and the accumulated survival rate of hepatolithiasis associated with intrahepatic cholangiocarcinoma were analyzed. Results Expression rates of NF-κB and EGFR were gradually raised from normal control group, control group to observing group (Plt;0.01). Expression of EGFR in tumor patients was related to histopathologic differentiation grading and the depth of tumor invasion (Plt;0.05), but not to gender, age, or lymph node metastasis (Pgt;0.05)； there were no significant relationships between the expression of NF-κB and factors described above (Pgt;0.05). The survival rate of patients with tumor expressed EGFR was significantly lower than that of patients with tumor non-expressed EGFR (Plt;0.01). Conclusions NF-κB expression is in the early stage during intrahepatic cholangiocarcinoma genesis. NF-κB and EGFR play cooperating roles during hepatolithiasis carcinogenesis process. Over expression of EGFR is related with poor differentiation and prognosis of tumor.
We had performed transjugular intrahepatic portosystemic stent shunt (TIPSS) in one hundred and three patients with advanced liver cirrhosis and portal hypertension from July,1993 to January, 1995. TIPSS was carried out successfully in ninty-eight out of 103 cases and the technical success rate was 95.2%. Acute variceal bleeding was immediatly controlled and portal pressure reduced by an average of 1.36±0.02 kPa after TIPSS. The disappearance of gastric cornoary and esophageal varices, the shrinkage of spleen and the reduction of ascite were observed . Three patients died of acute liver failure and one died of variceal redbleeding within 30 days of treatment. Mild encephalohthy was obserbed in 10 cases with TIPSS. At follow-up of 1～22 months, variceal rebleeding and ascite were observed in 6 patients and stenosis of shunt was evident is 12.5% of cases by the subsequent doppler sonography. According to this result, TIPSS is an effective method for the treatment of portal hypertension.
Objective To assess the efficacy and safety of S-adenosyl-l-methionine (SAMe) for outcome improvement of intrahepatic cholestasis of pregnancy. Methods Randomized controlled trials (RCT) and quasi-randomized controlled trials were identified from MEDLINE (1983 to 2003), The Cochrane Library (Issue 4,2003), EMBASE (1980 to 2003), China Hospital Digital Library (CHDL) and Wanfang data (1994 to 2003). We also handsearched the relative references. Two researchers evaluated the quality of the trials and extracted the data independently. RevMan software 4.2 was used for meta-analysis. Results Eight studies involving 424 pregnant women were included. The following data were the results of meta-analysis of SAMe for improvements: ① Reducing cesarean-section ratio: no significant difference was seen between SAMe and placebo groups with OR 1.00, 95%CI 0.23 to 4.33 and P= 1.00; significant differences were seen SAMe versus dexamethasone and SAMe versus Dianglining with OR 0.44, 95%CI 0.23 to 0.85 and P=0.01; OR 0.28 95%CI 0.10 to 0.75 and P=0.01 respectively。② Prolonging the period of pregnancy: SAMe had no significant difference compared with placebo groups with WMD=0.70, 95%CI －0.69 to 2.10, P=0.32. SAMe was more effective than dexamethasone, Ganyinling and Qianglining on prolonging the period of pregnancy with WMD=1.10，95%CI 0.46 to 1.74, P=0.000 07; WMD=2.50，95%CI 1.86 to 3.14, P≤0.000 01; WMD=2.20，95%CI 1.61 to 2.79, P≤0.000 01 respectively；③ Increasing the weight of the newborn: meta-analysis showed that SAMe group had not significant difference compared with placebo group on increasing the weight of the newborn with WMD=-26.27，95%CI -338.35 to 285.82, P=0.87. Significant differences were seen between SAMe and dexamethasone, SAMe and Ganyiling, SAMe and Qiangling with WMD=386.86，95%CI 134.41 to 603.31, P=0.002; WMD=410.00,95%CI 321.10 to 498.90, P≤0.000 01 respectively. ④ Fetal distress: There was no significant difference compared with dexamethasone and Kuhuang groups on decreasing the fetal distress with OR=0.47, 95%CI 0.14 to 1.16, P=0.23; OR=0.44, 95%CI 0.10 to 1.97, P=0.29 respectively; ⑤ Decreasing pollution of amniotic fluid: no significant differences were seen in SAMe versus dexamethasone, SAMe versus ursoddeoxycholic and SAMe versus Kuhuang with OR=0.46, 95%CI 0.21 to 1.02, P=0.06; OR=0.68, 95%CI 0.20 to 2.31, P=0.53; OR=0.82 95%CI 0.24 to 2.81,P=0.75 recpectively. ⑥ Newborn stifile: SAMe group had no significant difference compared with dexamethasone and Kuhuang groups on decreasing the Newborn stifile with OR=0.19, 95%CI 0.01 to 4.06, P=0.29; OR=0.31, 95%CI 0.08 to 1.13, P=0.08 respectively. Compared with Qianglining group, SAMe group had better effect on reducing ratio of newborn stifile with OR=0.09, 95%CI 0.02 to 0.42, P=0.002. ⑦ Improving Apgar scores: no significant differences were seen between SAMe and placebo, dexamethasone and ursoddeoxycholic with OR=0.25, 95%CI 0.02 to 3.04, P=0.28; OR=2.09, 95%CI 0.70 to 6.27, P=0.19; OR=1.22, 95%CI 0.35 to 4.19, P=0.75 respectively. Six RCTs mentioned the side effects of S-adenosy-l-methionine, only one RCT reported mild gastrointestinal irritation. Conclusions SAMe is partly effective on improving the pregnancy outcomes of intrahepatic choletasis of pregnancy, such as reducting cesarean-section ratio, prolonging the period of pregnancy and increasing the weight of the newborn. The specified efficacy and safety of SAMe require rigorously designed, randomized, double-blind and placebo-controlled trials to offer evidence.
ObjectiveTo discuss the CT imaging differences between mass-forming intrahepatic cholangiocarcinoma (ICC) and poorly-differentiated hepatocellular carcinoma (HCC). MethodThe clinical and CT data of 28 patients with mass-forming ICC (mass-forming ICC group) and 27 patients with poorly-differentiated HCC (poorly-differentiated HCC group), who were confirmed by pathological diagnosis in the West China Hospital from February 2014 to August 2014, were collected and analyzed retrospectively. ResultsThe contour, margin, enhancement patterns in the arterial phase and portal vein phase of the tumor had significant differences between the mass-forming ICC group and poorlydifferentiated HCC group (P < 0.05), in other words, the lobulated shape (15/28, 53.6%), indistinct margin (17/28, 60.7%), peripheral enhancement in the arterial phase (21/28, 75.0%) and prolonged enhancement in the portal vein phase (14/28, 50.0%) were more often seen in the mass-forming ICC group, while the poorly-differentiated HCC group were mainly the round shape (17/27, 63.0%), partially well-defined margin (18/27, 66.7%), diffuse heterogeneous enhancement in arterial phase (20/27, 74.1%) and wash out in the portal vein phase (18/27, 66.7%). The presence of bile duct dilatation in the the mass-forming ICC group was significantly higher than that in the poorly-differentiated HCC group﹝57.1% (16/28) versus 14.8% (4/27), P=0.001﹞. The size and enhancement degree of lymph node in the mass-forming ICC group were significantly bigger or higher than those in the poorly-differentiated HCC group (average lymph node size: 1.7 cm versus 1.3 cm, P=0.009; average enhancement degree of lymph node: 62.6 HU versus 51.8 HU, P=0.031). ConclusionCT features, such as tumor contour, margin, enhancement characteristics, the presence of bile duct dilatation, and the size and enhancement degree of lymph node, might help for differentiating mass-forming ICC from poorly-differentiated HCC, so that more timely selection of appropriate treatment strategies would be made.
ObjectiveTo overview the various molecular biological index to judge the prognosis of intrahepatic cholangiocarcinoma (ICC), in order to promote ICC patients follow-up treatment, improve survival rate, and quality of life of the patients. Methods"ICC" and "prognostic factor" were searched as key words by PubMed and CNKI series full-text database retrieval systems from 2000 to 2015. Totally 48 English papers and 15 Chinese papers were obtained. Choice criteria:the molecular biological index that affect the prognosis of ICC patients, and can effectively guide treatment. According to the choice criteria, 45 papers were finally analyzed. ResultsThe indicators of Homer1, mucin 1 (MUC1)\mucin 4 (MUC4), lactate dehydrogenase A (LDH-A), Beclin1, Smad4, protein tyrosine kinase-7 (PTK7), IMP3, cytokeratin 7 (CK7)/cytokeratin 20 (CK20), and sphingosine kinase 1 (SPHK1) could be used as prognostic factors in the survival of patients with ICC, and to determine tumor size and stage, vascular invasion, nerve injury, and lymph node metastasis, are of great clinical significance. ConclusionThese indicators have a significant meanning in the prognosis of ICC and the adjustment of the follow-up treatment.
