Cardiac and renal effects of liver cirrhosis in a growing animal model

ABSTRACT Purpose: To assess the biochemical, histological, histomorphometric and molecular effects of biliary duct ligation (BDL) induced liver cirrhosis in the heart and kidneys. Methods: Thirty-two weaning rats (21 days old, 50-70 g) underwent BDL and were divided in four groups (euthanasia after two, four, six, and eight weeks, respectively) and compared to control groups. Results: The animals' hearts of group 3 were bigger than those of the control group (p=0.042), including thinner right ventricle wall, decreased internal diameter of ventricles, and increased perivascular collagen deposition in left ventricle, as well as increased interstitial collagen in right ventricle after six weeks. In the kidneys of groups 3 and 4, bilirubin impregnation in the tubules, hydropic degeneration, loss of nuclei and lack of plasmatic membrane limits were noted. Nitric oxide synthase (NOS) gene expressions were higher in group 1 (p=0.008), and endothelial nitric oxide synthase (eNOS) gene expressions were elevated in all experimental groups (p=0.008, p=0.001, p=0.022, and p=0.013, respectively). In the heart, a decreased expression of eNOS in group 1 (p=0.04) was observed. Conclusions: Liver cirrhosis leads to histological and histomorphometric alterations in the heart and kidneys, with changes in the NOS and eNOS gene expressions, that may suggest a role in the associated myocardial and renal manifestations.

Detalles técnicos de la doble anastomosis hepático-yeyuno en Y de Roux, con base en la descripción de un caso / Technical details of double Roux-en-Y hepaticojejunostomy based on a clinical case description

La anastomosis hepático-yeyuno en Y de Roux se considera la técnica de elección para tratar lesiones quirúrgicas de la vía biliar, como su sección o resección. La pérdida de confluencia de los conductos hepáticos principales derecho e izquierdo es uno de los factores que incrementan la complejidad técnica durante el procedimiento y, en algunos de estos pacientes, se requiere una doble anastomosis hepático-yeyuno para garantizar resultados satisfactorios a largo plazo. Se describen los aspectos técnicos y los resultados posoperatorios del tratamiento quirúrgico empleado, con base en la intervención de una paciente con una lesión quirúrgica de la vía biliar y pérdida de la confluencia de los conductos hepáticos. La evolución de la paciente fue satisfactoria y se mantiene asintomática después de 12 meses de seguimiento. A pesar de ser una técnica compleja, la doble anastomosis hepático-yeyuno en Y de Roux resultó una opción segura de tratamiento en esta paciente

Roux-en-Y hepato-jejunostomy (RYHJ) is the technique of choice for the surgical treatment of bile duct injuries (BDI), such as section or resection. The loss of the hepatic confluence (LHC) increases the technical difficulties during the procedure and, in some of these patients, a doble-RYHJ is required to achieve a long term successful result. We report the technical aspects of the surgical technique as well as the results, based on the case of a young female patient with BDI and LHC. The patient shows a satisfactory evolution and remains asymptomatic during the 12 months of follow up. Double RYHJ, although technically demanding, resulted a safe option for treating this patient

Role of a liver pathology standardized scoring system in the diagnosis of congenital biliary atresia and its relationship with prognosis / 中华病理学杂志

Objective@#To evaluate the diagnostic value of a histologic scoring system in congenital biliary atresia and its prognostic relevance.@*Methods@#From January 2017 to June 2018 at Children′s Hospital of Fudan University, 172 wedge liver biopsy specimens were obtained from infants with neonatal cholestasis [119 patients with congenital biliary atresia (CBA) and 53 patients with non-obstructive cholestasis as control]. A pathologist, single-blinded to the final diagnosis, made the histological diagnosis individually based on an 8-feature (portal ductal proliferation, bile duct reaction, bile plugs in portal ductules, liver fibrosis, edema in portal region, cholestasis, inflammatory cells infiltration in portal region, and ductal plate malformation), 21-point scoring system.@*Results@#The main pathologic changes of biliary atresia were hepatocyte cholestasis, hyperplasia of bile ducts, fibrosis and infiltration of inflammatory cells in the portal area. There were significant difference in the degree of portal edema, bile duct hyperplasia and fibrosis between two groups (P<0.01). In addition, there were characteristic bile duct thrombosis in 97.5%(116/119) of the cases and abnormal development of bile duct plate in 9.2%(11/119) of the cases. Compared with non-CBA infant cholestasis group, the difference was statistically significant (P<0.05). The scoring system has high sensitivity, specificity (both 94.1%) and accuracy (94.3%) in the diagnosis of CBA. A score equal to or more than 11 points supported a diagnosis of CBA; whereas a score less than 11 points might suggest cholestasis. The degree of hepatic fibrosis and ductal plate malformation were related to prognosis.@*Conclusions@#The liver pathology scoring system (8-feature, 21-point) is more accurate in diagnosing CBA than previous methods, which may guide the clinicopathological diagnosis. This histological scoring system also helps to assess the prognosis of CBA.

Right hepatic artery syndrome / 中华肝胆外科杂志

Right hepatic artery syndrome refers to a syndrome of compression of extrahepatic bile duct by right hepatic artery,resulting in chronic biliary obstruction.In the severe cases,it can be complicated by bile duct stones,acute cholangitis and obstructive jaundice,and so on.This syndrome has a low incidence,lack of characteristic clinical manifestations and is often misdiagnosed as a bile duct tumor or bile duct stone.It is an important prerequisite to improve the recognition level of the syndrome and to pay attention to the imaging examination on the anatomic relationship between the site of bile duct stenosis and the right hepatic artery.The treatment should be based on the degree of pathological changes and complications.Laparoscopic right hepatic artery dissolution and biliary tract exploration are the most commonly preferred treatment methods.

Conducto subvesicular, nomenclatura anatómica para el conducto de Luschka y su importancia clínica. Revisión de tema / Subvesical Ducts, the Anatomical Nomenclature for the Bile Ducts of Luschka and its Clinical Importance. Topic Review

Introducción: El conducto subvesicular fue descrito por Hubert Luschka como pequeños ductos biliares derivados de la pared de la vesícula biliar. Algunos autores lo describen como un ducto que lleva el drenaje desde el parénquima hepático hasta la vesícula, otros utilizan el término describiéndolo como un conducto que drena desde el parénquima hepático hasta las vías biliares extrahepaticas. Se planteó una revisión bibliográfica de la descripción anatómica del epónimo conducto de Luschka y de la terminología anatómica propuesta conducto subvesicular o subvesical, dada su importancia clínica como causa de fuga biliar. Metodología: Se realizó una revisión bibliográfica en bases de datos y bibliotecas electrónicas. Con ventana de tiempo personalizada desde 2006 hasta 2016, se obtuvo un total de 82 artículos, posteriormente se realizó un resumen analítico especializado, seleccionando un total de 46. Resultados: No se encontró consenso en la descripción anatómica del epónimo, ni en la descripción de la terminología internacional. Las lesiones de la vía biliar durante la colecistectomía se presentan como una complicación poco frecuente (0.1 - 1.5%); sin embargo, tienen repercusiones en varios ámbitos y una morbi-mortalidad considerable. Conclusiones: Se evidenció discrepancia en la nomenclatura utilizada para la descripción de estos conductos, puesto que se denomina de manera indiscriminada como conducto de Luschka a todos los ductos biliares que se encuentran en la fosa biliar. La relevancia clínica radica en que es la segunda causa de fuga biliar iatrogénica y la asociación entre el conducto subvesical y carcinomas ductales. Aún se necesitan más estudios principalmente locales para identificar su incidencia y prevenir complicaciones...(AU)

Introduction: The duct was described by Hubert Luschka as small bile ducts derived from the wall of the gallbladder. Some authors describe it as a duct leading to drainage from the hepatic parenchyma to the gallbladder; others use the term to describe it as a conduit draining from the hepatic parenchyma to the extrahepatic bile ducts. This article presents a literature review of the anatomical description of the eponymous Luschka conduit and the proposed anatomical terminology subvesicular or subvesical conduit, given its clinical importance as a cause of biliary leakage. Methodology: A bibliographic review was carried out in databases and electronic libraries. With a customized time window from 2006 to 2016, obtaining a total of 62 articles, a specialized analytical summary was subsequently performed, selecting a total of 46. Results: No consensus was found in the anatomical description of the eponym, nor in the description of the International terminology. Lesions of the biliary tract during cholecystectomy present as a rare complication (0.1 - 1.5%) but have repercussions in several areas and considerable morbidity and mortality. Conclusions: There was a discrepancy in the nomenclature used for the description of these ducts. It is indiscriminately named as the luschka's conduit for all bile ducts found in the biliary fossa. The clinical relevance is that it is the second cause of iatrogenic biliary leakage and the association between the subvesical duct and ductal carcinomas. More local studies are still needed to identify its incidence and prevent complications...(AU)

Introdução: O ducto subvesicular foi descrito por Hubert Luschka como pequenos ductos biliares derivados da parede da vesícula biliar. Alguns autores descrevem isso como um ducto que leva a drenagem do parênquima hepático para a vesícula biliar, outros usam o termo para descrevê-lo como um canal que drena do parênquima hepático para os ductos biliars extra-hepáticos. Foi proposta uma revisão bibliográfica da descrição anatômica do canal epônimo de Luschka e da derivação anatômica proposta subvesicular ou subvesical, dada sua importância clínica como causa de vazamento biliar. Metodologia: foi realizada uma revisão bibliográfica em bancos de dados e bibliotecas eletrônicas. Com uma janela de tempo personalizada de 2006 a 2016, foi obtido um total de 82 artigos, seguido de um resumo analítico especializado, selecionando um total de 46. Resultados: Nenhum consenso foi encontrado na descrição anatômica do epônimo, nem na descrição da terminologia internacional. As lesões do trato biliar durante a colecistectomia apresentam-se como uma complicação rara (0.1 ­ 1.5%); no entanto, têm repercussões em várias áreas e considerável morbidade e mortalidade. Conclusões: houve uma discrepância na nomenclatura utilizada para a descrição desses ductos, uma vez que é indiscriminadamente referido como o canal de Luschka a todos os canais biliares encontrados na fossa biliar. A relevância clínica é que é a segunda causa de vazamento biliar hepático e a associação entre ducto subvesical e carcinomas ductais. Mais estudos locais ainda são necessários para identificar sua incidência e prevenir complicações...(AU)

Tratamento endoscópico das estenoses biliares pós-transplante hepático: revisão sistemática da literatura e metanálise / Endoscopic treatment of post-liver transplantation biliary strictures: systematic literature review and meta-analysis

As complicações biliares mais comuns pós-transplante hepático são as estenoses da anastomose, as estenoses não-anastomóticas e as fístulas biliares e podem ocorrer de diferentes modos, de forma isolada ou associada. A origem do enxerto (doador cadáver ou doador vivo) tem influência na incidência de estenose biliar, bem como na resposta ao tratamento endoscópico. A terapêutica endoscópica utilizando-se esfincterotomia, dilatação balonada da estenose e inserção de próteses biliares através da CPRE é utilizada como método inicial de tratamento dessas complicações. Objetivos: Comparar as diferentes técnicas de tratamento endoscópico das estenoses biliares pós-transplante hepático. Método: Foi realizada uma revisão sistemática da literatura e metanálise sendo a busca conduzida nas bases MEDLINE, EMBASE, Scielo - LILACS e Biblioteca Cochrane até junho de 2015. A metanálise foi executada utilizando-se os softwares Review Manager, 2012 (RevMan) versão 5.2 e OpenMetaAnalyst e os cálculos dos desfechos foram feitos comparando-se os resultados dos estudos incluídos utilizando-se a diferença de risco absoluto e adotando-se um intervalo de confiança (IC) de 95%. Os estudos foram agrupados comparando-se transplantes hepáticos com doador cadáver versus doador vivo; dilatação biliar endoscópica com balão exclusiva versus dilatação biliar endoscópica com balão associada à inserção de próteses plásticas e próteses biliares plásticas comparadas à prótese biliar metálica por endoscopia. Os desfechos clínicos analisados foram incidência da estenose biliar, falha do tratamento endoscópico, resolução da estenose, recorrência da estenose e complicações. Resultados: Foram recuperados 1.110 artigos, sendo motivo de análise dez ensaios clínicos, com apenas um Ensaio Clínico Randomizado e nove Ensaios Clínicos não randomizados, dos quais sete foram incluídos na metanálise. Comparando-se doador cadáver e doador vivo observou-se redução da incidência de estenose biliar...

The most common biliary complications after liver transplantation are anastomotic strictures, non-anastomotic strictures and biliary fistulas and they can occur in different fashions, isolated or in combination. Graft source (cadaveric liver donor or living liver donor) has an influence on the incidence of biliary strictures as well as on the response to endoscopic treatment. The endoscopic treatment using sphincterotomy, balloon dilation and insertion of biliary stents by ERCP (Endoscopic Retrograde Cholangiopancreatography) is used as an initial endoscopic approach to treat these complications. Objectives: To compare different endoscopic techniques to treat post-liver transplantation biliary strictures. Method: It was performed a systematic review of the literature and meta-analysis and the search was carried out on MEDLINE, EMBASE, Scielo-LILACS and Cochrane Library databases until June, 2015. The meta-analysis was made using Review Manager, 2012 (RevMan) version 5.2 and OpenMetaAnalyst software and the calculations of the outcomes were made comparing the results from the included papers by using the difference in absolute risks, adopting a confidence interval of 95%. The studies were grouped comparing cadaveric liver donor versus living liver donor grafts; exclusive balloon dilation versus balloon dilation associated with plastic stents insertion; and plastic stents versus totally covered selfexpandable metal stents. The clinical outcomes were biliary stricture incidence, endoscopic treatment failure, stricture resolution, stricture recurrence and complications. Results: There were retrieved 1,100 articles. Ten clinical trials were analyzed, with just one Randomized Clinical Trial and nine Non-Randomized Clinical Trials, out of which seven were included in the meta-analysis. When comparing cadaveric liver donor transplantation to living liver donor transplantation, it was observed a decrease in the incidence of biliary strictures (p=0.0001), as well as...

ObjectiveTo explore the feasibility and efficacy of percutaneous transhepatic approach in the treatment of intrahepatic and extrahepatic bile duct stones. MethodsNineteen patients with bile duct stones who were treated in our hospital from January 2000 to October 2014 were enrolled as subjects. In the treatment of bile duct stones, all patients received percutaneous transhepatic approach combined with the application of cholangioscopy and lithotripsy equipment. ResultsIn the 19 patients, 12 had the stones successfully removed in a single session, 5 had the stones completely removed through the liver sinus in three sessions, and 2 had residual stones in intrahepatic tertiary bile ducts. The success rate of lithotomy reached 89.47%(17/19). ConclusionThe percutaneous transhepatic approach achieves minor surgical invasion and slight pain in the treatment of bile duct stones, which can be selectively used based on patients′ condition.

Identification and treatment of variation of extrahepatic bile duct in laparoscopic cholecystectomy / 临床肝胆病杂志

ObjectiveTo investigate the identification and treatment of variation of extrahepatic bile duct in laparoscopic cholecystectomy (LC), and to reduce the occurrence of bile duct injury. MethodsThis study included 60 patients who received LC in the People′s Hospital of Caidian District in Wuhan and had structural variation of extrahepatic bile duct found during the operation from January 2012 to January 2014. The clinical data were retrospectively analyzed, and the intraoperative and postoperative conditions were summarized. ResultsDuring operation, cystic duct variation was found in 32 cases, abnormal position of the point where the cystic duct joins the extrahepatic bile duct in 20 cases, the cystic duct and the common hepatic duct having the common wall before joining the common bile duct in 2 cases, aberrant bile duct in the gallbladder bed in 2 cases, and accessory hepatic duct in 4 cases. Fifty-one patients (85%) successfully underwent LC; 9 patients (15%) were converted to open surgery. All patients finished surgery successfully. There were 2 cases of postoperative complications; one patient developed residual stones in the bile duct, and bile leakage occurred in the other patient at one week after LC, who recovered after reoperation. All patients were cured and discharged, without severe complications such as intraperitoneal hemorrhage, infection, and intestinal injury. ConclusionIdentifying the structural variation of extrahepatic bile duct, dissecting the Calot′s triangle meticulously, and determining the type of variation of extrahepatic bile duct play important roles in LC and significantly reduce the incidence of bile duct injury.

Analysis of the causes of reoperation and countermeasures of intra-and extrahepatic bile duct stones after op-eration / 中国基层医药

Objective To explore the extrahepatic bile duct stones after reoperation cause analysis and coun-termeasures.Methods Clinical data of 150 patients with liver surgery gallstone surgery again were retrospectively analyzed,according to the first reason for liver from gallstone surgery will be divided into the three groups:group hepa-tolithiasis ( group A,100 cases) ,gallstones group ( group B,30 patients) ,common bile duct stones group ( group C, 20 cases) .The reasons for reoperation were analyzed.Results In intrahepatic bile duct stones reoperation patients, the recurrence of liver gallstones was 98 cases(65.3%),common bile duct cysts and Caroli disease was 35 cases (23.3%),anastomotic stenosis in 17 cases(11.3%);The postoperative complication rate of group A(44.0%) was significantly higher than that of group B(13.3%) and group C(15.0%)(χ2 =9.32,5.88,all P<0.05);The sec-ondary and post-operative inflammation stone recurrence within 5 years of group A was 32.0%,which was significant-ly higher than 6.7%of group B and 10.0%of group C(χ2 =7.67,3.97,all P<0.05).Conclusion The intrahe-patic bile duct stones are the main types of reoperation after liver gallstones,gallstones and liver recurrence is the main cause of its secondary surgery.It should be make clear the disease cause of preoperation, take a different surgical options for patients with different types of stones,prevention,and avoid the occurrence of postoperative complications, which can effectively reduce the risk of secondary surgery to alleviate the suffering of patients.

Choice of the treatment of palliative therapy of jaundice in cholangiocarcinom / 国际外科学杂志

Objective To compare the efficacy and indications between the biliary bypass laparotomy surgery.and the two different kinds of biliary stent insertion surgery in the palliative alleviating jaundice of cholangiocarcinoma.Methods From March 2008 to March 2013,69 patients treated with palliative alleviating jaundice therapy of cholangiocarcinoma were included,who were all came from the Third Affiliated Hospital of Guangzhou Medical University.Including 17 patients who treated with the open biliary bypass surgery and 52 patients who treated with interventional therapy.We analysed the differences between these cases of biliary drainage operations in the recent jaundice reduction rate,average stay,mortality rate,the incidence of related complications,et al.Results All these different drainage ways had good effect in alleviating jaundice,incidence of alleviating jaundice have no obvious difference (P ＞ 0.05).Compared to the open biliary bypass surgery,interventional therapy had obvious advantages in the average stay and postoperative survival (P ＜ 0.05).The pancreatitis rate was lower in Percutaneous Group than that in Endoscopic Group (P ＜ 0.05).incidence of biliary tract infection and biliary tract bleeding have no obvious difference (P ＞ 0.05).There were no significant differences between the success rates of in biliary stent insertion operation in patients with each model cholangiocarcinoma (P ＞ 0.05).Conclusions Among the therapies of the palliative alleviating jaundice of cholangiocarcinoma,the internal biliary drainage of biliary stent insertion operation was superior to the treatment of the biliary bypass laparotomy.As to biliary stent insertion operations,endoscopic biliary stenting surgery should be the preferred choice.

Functional Self-Expandable Metal Stents in Biliary Obstruction

Biliary stents are widely used not only for palliative treatment of malignant biliary obstruction but also for benign biliary diseases. Each plastic stent or self-expandable metal stent (SEMS) has its own advantages, and a proper stent should be selected carefully for individual condition. To compensate and overcome several drawbacks of SEMS, functional self-expandable metal stent (FSEMS) has been developed with much progress so far. This article looks into the outcomes and defects of each stent type for benign biliary stricture and describes newly introduced FSEMSs according to their functional categories.

Primary Biliary Lymphoma Mimicking Cholangiocarcinoma: A Characteristic Feature of Discrepant CT and Direct Cholangiography Findings

Primary non-Hodgkin's lymphoma arising from the bile duct is extremely rare and the reported imaging features do not differ from those of cholangiocarcinoma of the bile duct. We report a case of a patient with extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue (MALT), who presented with obstructive jaundice and describe the distinctive radiologic features that may suggest the correct preoperative diagnosis of primary lymphoma of the bile duct. Primary MALT lymphoma of the extrahepatic bile duct should be considered in the differential diagnosis when there is a mismatch in imaging findings on computed tomography or magnetic resonance imaging and cholangiography.

Progress of chemoradiotherapy in management of extrahepatic biliary system cancer / 国际肿瘤学杂志

Extrahepatic biliary system cancer(EBSC)is an uncommon disease with a poor prognosis. There is no change to making radical resection in most patients because most of the diseases are diagnosed at late stage.Chemoradiotherapy has been a major therapeutic modality of EBSC.In recent year,the progress of chemoradiotherapy has been made in management of resectable and unresectable EBSC.

Carcinoid Tumor of the Extrahepatic Bile Duct

Carcinoid tumors of the extrahepatic bile ducts are exceedingly rare, accounting for between 0.1 and 2% of all gastrointestinal carcinoid tumors, with most reported cases arising from the gallbladder. Only 34 cases of carcinoid tumor arising from the extrahepatic bile duct have been documented in the world literature. We report one case of a carcinoid tumor of the common bile duct. A 67-year-old woman sought treatment for obstructive jaundice, accompanied by epigastric pain. The laboratory and imaging studies were consistent with a malignant obstruction in the common bile duct. We performed a Pylorus preserving pancreaticoduodenectomy. Pathologically, an ill-demarcated mass, measuring 1.6x1.5x0.5 cm in size, was noted in the common bile duct, with infiltration to the adjacent pancreatic tissues. Immunohistochemically, the mass was shown to be chromogranin, synaptophysin and CD56 positive. The final pathological diagnosis was one of a well- differentiated carcinoid tumor of a malignant nature. The patient, who underwent a curative surgical resection, was alive and disease free at time of this published report.

Unilocular Extrahepatic Biliary Cystadenoma Mimicking Choledochal Cyst: A Case Report

We report here on a case of extrahepatic biliary cystadenoma arising from the common hepatic duct. A 42-year-old woman was evaluated by us to find the cause of her jaundice. Ultrasonography and CT showed a cystic dilatation of the common hepatic duct and also marked dilatation of the intrahepatic duct. Direct cholangiography demonstrated a large filling defect between the left hepatic duct and the common hepatic duct; dilatation of the intrahepatic duct was also demonstrated. Following excision of the cystic mass, it was pathologically confirmed as a unilocular biliary mucinous cystadenoma arising from the common hepatic duct.

Restrictive Cardiomyopathy in a Patient with Extrahepatic Biliary Atresia

The most commonly associated anomalies in patients with extrahepatic biliary atresia are cardiovascular, digestive and splenic defects. Of the cardiovascular anomalies, there are very few reports of biliary atresia with cardiomyopathy. We report the first case of a child with extrahepatic biliary atresia and restrictive cardiomyopathy. The patient was a 13-month-old boy diagnosed with extrahepatic biliary atresia at the age of 2 months, when he underwent laparotomy for definite diagnosis.Hepatic portoenterostomy was performed after confirmative cholangiogram. Recently, he developed severe cough and dyspnea, and his respiratory symptoms worsened. Chest radiograph showed cardiomegaly. Two- dimensional echocardiography showed marked biatrial enlargement. On M- mode echocardiogram, a slight increase in left ventricular dimension was seen in early diastole with a relatively good left ventricular function. Mitral inflow Doppler tracing showed an increased E-velocity (1.1 m/sec) with decreased deceleration time (75 m/sec), and increased E/A ratio (0.33). He was diagnosed as having restrictive cardiomyopathy with characteristic echocardiographic features.

Experimental study on the radioactive plastic biliary stents / 中华消化杂志

Objective To design radioactive biliary stents and to evaluate the feasibility and safety of the stents.Methods Plastic stents with inserted iodine-125 seeds were designed and tested in sixteen normal pigs. In the brachytherapy group,the pigs were implanted radioactive stents in the common bile duct (CBD) and then divided into three groups on the basis of radiation dose of the reference point,50 Gy group (n=4),100Gy group (n=4),and 150 Gy group (n=4).In the control group,the same plastic stents with non-radioactive seeds were implanted (n=2),whilst in the blank control group,no stents were implanted (n=2).Blood routine,serum amylase,liver and kidney function were tested before and 1,7,14,30,60 days after the implantation of stents. Animals were sacrificed on the 14,30 and 60 days after stem implantation.Some relevant index such as perito- neal bleeding and inflammation,ascites,injury of adjacent organs,as well as perforation,stricture and dilatation of bile duct were investigated.Bile duct tissues were stained with H-E,and observed under microscopy. Results The radioactive plastic biliary stents were successfully prepared and implanted.There was no effusion, hemorrhage or necrosis in the adjacent organs of radioactive biliary stent implanted group.Perforation of the CBD wall was not observed in the brachytherapy group.By pathological examination in the CBD,obvious hyperplasia of the mucosa and mucosal glands were seen in the control group.Necrosis of mucosal layer existed in brachy- therapy groups.In 50 Gy group,mucosal layer was incomplete and mild hyperplasia of mucosal glands was seen. In 100 Gy group,mucosal layer disappeared and almost no hyperplasia of the mucosal glands could be found.In 150 Gy group,mucosal layer disappeared and mucosal glands obviously decreased.There were no obvious abnormalities noted in blood tests after implantation in each group.Conclusions The design of radioactive biliary stents are feasible and safe.The radioactive stents have obvious radiation effect besides the mechanical effect on the mucosal layer of CBD.

Perioperative treatment of intra-and extra-hepatic cholelithinsis in patients with liver cirrhosis / 中国普通外科杂志

Objective To study the perioperative treatment of intra-and extra-hepatic cholelithinsis in patients with liver cirrhosis . Methods The clinical data of intra-and extra-hepatic cholelithinsis in patients with liver cirrhosis in our hospital in resent 10 years was retrospectively analyzed. Results According to the preoperative examation, improving hepatic function(turn child class C to A or B), correcting the coagulation disturbance,decreasing portal vein pressure preoperatively,and proforming operation carefully to reduce bleeding,and giving support treatment and liver care treatment to improve the liver function further postoperatively etc were made.Fifteen cases remained stones, 5 cases appearred chronic liver failure,2 cases appearred kidney failure ,the other 69 cases recovered well. Conclusions If optimizing perioperative treatment is given, favorable effect might be obtained in intra-and extra-hepatic cholelithinsis in patients with liver cirrhosis.
