ObjectiveTo study the clinical value of digital technology assisted minimally invasive surgery in diagnosis and treatment of hepatolithiasis. MethodsThe image data of 64-slice spiral CT scanning were obtained from five patients of complicated hepatolithiasis and introduced into medical image three-dimensional visualization system (MI-3DVS) for three-dimensional reconstruction. On the basis of the data of three-dimensional reconstruction, minimally invasive surgical planning of preoperation was made to obtain reasonable hepatectomy and cholangiojejunostomy, and then preoperative emulational surgery was carried out to minimize the extent of tissue damage and provide guidance to actual operation. ResultsLiver, biliary system, stone, blood vessel, and epigastric visceral organ were successfully reconstructed by MI-3DVS, which showed clearly size, number, shape, and space distribution of stone, and location, degree, length, and space distribution of biliary stricture, and anatomical relationship of ducts and vessels. The results of three-dimensional reconstruction were successfully confirmed by actual operation, which was in accordance with emulational surgery. There was no operative complication. No retained stone in internal and external bile duct was found by Ttube or other supporting tube cholangiography on one month after operation. ConclusionThree-dimensional digitizing reconstruction and individual emulational surgery have important significance in diagnosis and treatment of complicated hepatolithiasis by minimally invasive technique.
ObjectiveTo investigate the effectiveness of epidermal growth factor receptor antagonist (AG-1478) on chronic proliferative cholangitis (CPC), so as to investigate new treatment approach for hepatolithiasis associated with CPC. MethodsForty-six SD rats were divided into 5 groups: CPC model group (n=10), only made models. AG-1478 treatment group (divided into 3 mg/kg， 6 mg/kg， and 12 mg/kg groups, n=10 per group), the common bile ducts in CPC animal model received an intralumenal administration of AG-1478 at the meantime of modeling, followed by intraperitoneal AG-1478 injection of 1.5 mg/(kg·d) for 7 days. Sham operation group (SO group, n=6). Subsequently, histopathological observation, immunohistochemistry, real time PCR， and Western blot were used to evaluate the mRNA expression and influence of AG-1478 on the hyperplasia （EGFR， ki-67， BrdU， collagen Ⅰ protein） and lithogenic potential (Mucin 5AC) of CPC. ResultsCompared with CPC model group, the expressions of EGFR, ki-67， and BrdU were obviously decreased in the AG-1478 treatment group. Also, the inhibition of hyperplasia of biliary epithelium and collagen fibers were confirmed by histopathological observation. Additionally, the expressions of Mucin 5AC mRNA and collagen Ⅰ protein remarkable decreased in the AG-1478 treatment group (Plt;0.05). Conclusions EGFR inhibitor (AG-1478) could shows inhibitory effectivenss on the CPC-mediated hyperplasia and lithogenic potential, and therefore holds promise as the new treatment approach for CPC.
ObjectiveTo observe the effects of oral Xiaoyan Lidan tablets(XYLDT) on the bile composition(total bile acids, cholesterol, phospholipids) in patients with intrahepatic duct stones after common bile duct exploration(CBDE) with T tube drainage, to explore its possible preventive effects on stone recurrence. MethodsForty consecutive patients with intrahepatic bile duct stones who underwent CBDE with T tube drainage were randomly divided into experi mental group and control group. XYLDT were administrated at day 4 after surgery in experimental group(n=20), while none of medication were given in control group(n=20). 2 mL of bile was collected through T tube in both groups at day 1, 2, 3, 7, 14, and 21 postoperatively. Total bile acids(TBA), cholesterol(CHO), and phospholipids(PLIP) in bile were measured, and TBA/CHO ratio and PLIP/CHO ratio were calculated respectively. The results were statistical analyzed. ResultsThe demographic data in both groups including age, gender, height, weight, preoperative concomitant diseases, operative time, postoperative complications, hospital stays, serum total bilirubin, direct bilirubin, alanine aminotransferase(ALT), aspartate aminotransferase(AST), and amylase were not significantly different(P > 0.05). The measurements of TBA, CHO, PLIP, and the ratio of TBA/CHO and PLIP/CHO in bile were not significant on day 1, 2, and 3 after surgery in both groups(P > 0.05). In experimental group, the TBA, CHO, and PLIP on day 7, 14, and 21 after surgery were significantly increased compared with the control group(P < 0.05). The ratio of TBA/CHO on day 7, 14, and 21 was 2.17±0.29, 2.29±0.44, and 2.59±0.58, the ratio of PLIP/CHO was 2.03±0.68, 2.84±0.64, and 2.86±0.77, respectively, which were also significantly increased compared with the control group(P < 0.05). ConclusionsOral XYLDT can increase the secretion of TBA, CHO, and PLIP, elevate the TBA/CHO and PLIP/CHO ratio, and change the bile composition which may increase the dissolution of cholesterol in the bile. Presumably, oral XYLDT may have preventive effects in the recurrence of intrahepatic bile duct stones.
Objective To observe the effect of gefitinib on expression of epidermal growth factor receptor (EGFR) in bile duct epithelial cells, and the feasibility of inhibiting hyperplasia of bile duct epithelial cells with gefitinib. Methods Sixty-one patients with hepatolithiasis having to be in hospital for surgery from the First People’s Hospital of Shuangliu county were selected, with 25-65 years old, average 46.92 years. The patients were randomly divided into therapy group and control group. There were 30 cases in therapy group, in which fine duct was placed on lesion bile duct during operation, and through whom gefitinib solution was perfused after operation. There were 31 cases in control group with only T tube drainage after operation. The bile duct sample was obtained respectively during the operation and 6 weeks and 12 weeks after operation. The histology and expression change of EGFR were observed by HE staining, immunohistochemistry and RT-PCR method respectively. Results There were no significant differences in pathohistology changes of bile duct and the EGFR protein and mRNA expression between therapy group and control group during operation. The hyperplasia of epithelium mucosae and submucosal gland in the therapy group were obviously decreased as compared with those in control group, the EGFR mRNA and protein expression in therapy group were weaker than those of control group （Plt;0.05） 6 weeks and 12 weeks after gefitinib treatment. Conclusion EGFR is overexpressed in the chronic proliferative cholangitis, and continuously local application of gefitinib after operation can specifically interrupt the activation and expression of EFGR and then effectively inhibit the hyperplasia of bile duct epithelial cells.
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.
【Abstract】ObjectiveTo evaluate the advances in minimally invasive surgery treatment for hepatolithiasis. MethodsLiteratures about the advances in minimally invasive surgery treatment for hepatolithiasis were collected and reviewed. ResultsHepatectomy and bile duct exploration using laparoscopy can get better effect. Fibrocholedochoscopy play an important role in the course of operation and after operation for hepatolithiasis. ConclusionThe individualization treatment program should be used for hepatolithiasis. Association application of multipathway minimally invasive operation, such as laparoscopy, fibrocholedochoscopy and so on, can increase the cure rate of hepatolithiasis.
Objective To summarize the experience of applying biliary balloon dilator to prevent rebleeding after operation for hepatolithiasis combined with hemobilia. Methods From 2003 to 2008, 11 patients were reoperated to stop from hemobilia by biliary balloon dilator’s application after operation for hepatolithiasis combined with hemobilia, and whose clinical data were collected and analyzed. Results In 11 cases, 7 were males and 4 were females. Eight cases were transferred from other hospitals. When intrahepatic duct bleeding was stopped, the biliary balloon dilator was placed at the right site under the guide of choledochoscope. Hemobilia occurred in 4 patients and biliary balloon dilator was opened to compress for 2 h, then decompress for 0.5 h alternately. In all of 4 patients, bleeding was stopped successfully, of which, 1 patient got hemobilia again 5 d after the first bleeding, and was also stopped by the same method. Conclusions After operation on hepatolithiasis combined hemobilia, rebleeding happens in some cases. Preset of biliary balloon dilator at the prebleeding site and opening it when rebleeding happens can get instant hemostasis, which may be a simple and effective treatment choice.
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 investigate the recurrence of hepatolithiasis and reoperation and their relation to the location of intrahepatic stone. MethodsTwo hundred and twentysix patients of hepatolithiasis operated upon in the period of 1990-1995 were retrospectively analysed.ResultsAmong those patients, there were 101 patients (44.7%) had previous operation for the gallstones diseases including cholecystectomy for gallbladder stones (n=21, 20.8%), choledocholithotomy (n=72, 71.3%),liver segmentectomy (n=6， 5.9%), and choledochojejunostomy (n=2, 2.0%). The operative mortality was 5.0% for the reoperation group and none for the first time operation for hepatolithiasis.Conclusion Although the liver resection is an ideal surgical method to eradicate the diseased lesion and to minimize the malignant changes especially in primary hepatolithiasis (type I, or IE)， choledochojejunostomy is only recommended for the secondary type (type IE or IE) where possible. In the management of hepatolithiasis, the complete information of biliary tract is needed for the choice of surgical methods.
After analysising 15 patients with portal hypertension (PHT) in secondary biliary cirrhosis due to hepatolithiasis, the authors consider that the surgical procedure depends on indivedual’s specificity: majority of patients with PHT but no hemorrhage may be treated by removing the hepatobiliary stone, resolving the bile duct stricture and then reconstructing it as the first step. Whether or not to dispose of PHT depended on the postoperative condition. If the patient had previous hemorrhage and is accompanied by severe obstructive jaundice, splenectomy with shunt and simple biliary external drainage is the choice and removal of stone with biliary tract reconstruction will be performed in the second stage. Meanwhile, it is very important to monitor perioperative condition of the patient and treat the complications.
