Imaging diagnosis of extrahepatic biliary tract obstruction with acquired portosystemic shunt in a cat / 대한수의학회지

A 2-year-old, spayed female, Korean domestic short-hair cat was presented with depression and vomiting. The patient had history of weight loss lasting seven months. Physical examination revealed icterus in the pinna, oral mucosa, and sclera. Based on ultrasonography and computed tomography, tentative diagnosis was extrahepatic biliary tract obstruction with acquired portosystemic shunt (PSS). Tumor or inflammation of hepatobiliary system was suspected as the cause of obstruction of the common bile duct. But it could not be determined without biopsy. The severely dilated cystic duct was considered to cause portal hypertension and secondary multiple PSS. The patient expired without histopathologic examination.

A Double-Layered Covered Biliary Metal Stent for the Management of Unresectable Malignant Biliary Obstruction: A Multicenter Feasibility Study

BACKGROUND/AIMS: The covered self-expandable metal stent (CMS) was developed to prevent tumor ingrowth-induced stent occlusion during the treatment of malignant biliary obstruction. However, complications such as cholecystitis, pancreatitis, and stent migration can occur after the endoscopic insertion of CMSs. The aim of the present study was to assess the efficacy and safety of a double-layered CMS (DCMS) for the management of malignant bile duct obstruction. METHODS: DCMSs were endoscopically introduced into 59 patients with unresectable malignant extrahepatic biliary obstruction at four tertiary referral centers, and the patient medical records were retrospectively reviewed. RESULTS: Both the technical and functional success rates were 100%. Procedure-related complications including pancreatitis, cholangitis, stent migration, and liver abscess occurred in five patients (8.5%). The median follow-up period was 265 days (range, 31 to 752 days). Cumulative stent patency rates were 68.2% and 40.8% at 6 and 12 months, respectively. At the final follow-up, the rate of stent occlusion was 33.9% (20/59), and the median stent patency period was 276 days (range, 2 to 706 days). CONCLUSIONS: The clinical outcomes of DCMSs were comparable to the outcomes previously reported for CMSs with respect to stent patency period and complication rates.

Effect of glutamine supplementation on left colon healing in rats with extrahepatic biliary obstruction

PURPOSE: To evaluate the influence of glutamine and obstructive jaundice on left colon healing in rats. METHODS: Sixteen male rats were allocated across four groups: LG - Common bile duct ligation followed by colotomy and bowel suture on postoperative day 7. Supplementation with glutamine 2% from day 4 after duct ligation until euthanasia. L - Common bile duct ligation followed by colotomy and bowel suture on postoperative day 7. No glutamine supplementation. M - Common bile duct manipulation followed by colotomy and bowel suture on postoperative day 7. No glutamine supplementation. MG - Common bile duct manipulation followed by colotomy and bowel suture on postoperative day 7. Supplementation with glutamine 2% from day 4 after duct manipulation until euthanasia. On the day of euthanasia, bursting pressure of the sutured bowel segment was measured and samples were collected for histopathological analysis. RESULTS: There were no differences in bursting pressure among groups : LG vs. M (110 ± 28 vs. 173 ± 12; p = 0.08). Groups L and MG were not different from group M (156 ± 12 and 118 ± 22. Glutamine supplementation was associated with less edema, polymorphonuclear lymphocyte infiltration, bacterial colonies, and abscess formation, as well as with increased collagen formation. CONCLUSION: Obstructive jaundice had no negative effect and glutamine supplementation had no positive effect on colonic scar strength in rats. .

Management of Obstructive Jaundice Caused by Hepatocellular Carcinoma / 대한췌담도학회지

Jaundice is one of the poor prognostic factors in the patient with hepatocellular carcinoma (HCC). In HCC patients, the most common cause of jaundice is liver parenchymal dysfunction and jaundice due to biliary obstruction is relatively rare. However, it is clinically important because biliary obstruction can be treated effectively with biliary drainage procedure and by that quality of life and survival of the patient can be improved. It is important to identify the mechanism and location of the bile duct obstruction for an appropriate management of the biliary obstruction. Endoscopic retrograde biliary drainage (ERBD) has commonly been selected as the first-line treatment. However, percutaneous transhepatic biliary drainage or endoscopic ultrasound guided biliary drainage also can be used when the endoscopic approach is impossible or when ERBD fails. Between two types of stents - plastic or self-expandable metal, there is no definitive evidence about which one is superior. Stent type should be selected according to the characteristics of obstruction and expected survival of patient.

Increase of glyoosaminoglycans and metalloprotenases 2 and 9 in liver extracelllular matrix on early stages of extrahepatic cholestaiis / Aumento de glicosaminoglicanos e metaloproteinases 2 e 9 na matriz extracelular de fígado em estágios iniciais de colestase extra-hepática

Context Cholestasis produces hepatocellular injury, leukocyte infiltration, ductular cells proliferation and fibrosis of liver parenchyma by extracellular matrix replacement. Objective Analyze bile duct ligation effect upon glycosaminoglycans content and matrix metalloproteinase (MMPs) activities. Methods Animals (6-8 weeks; n = 40) were euthanized 2, 7 or 14 days after bile duct ligation or Sham-surgery. Disease evolution was analyzed by body and liver weight, seric direct bilirubin, globulins, gamma glutamyl transpeptidase (GGT), alkaline phosphatase (Alk-P), alanine and aspartate aminotransferases (ALT and AST), tissue myeloperoxidase and MMP-9, pro MMP-2 and MMP-2 activities, histopathology and glycosaminoglycans content. Results Cholestasis caused cellular damage with elevation of globulins, GGT, Alk-P, ALT, AST. There was neutrophil infiltration observed by the increasing of myeloperoxidase activity on 7 (P = 0.0064) and 14 (P = 0.0002) groups which leads to the magnification of tissue injuries. Bile duct ligation increased pro-MMP-2 (P = 0.0667), MMP-2 (P = 0.0003) and MMP-9 (P<0.0001) activities on 14 days indicating matrix remodeling and establishment of inflammatory process. Bile duct ligation animals showed an increasing on dermatan sulfate and/or heparan sulfate content reflecting extracellular matrix production and growing mitosis due to parenchyma depletion. Conclusions Cholestasis led to many changes on rats’ liver parenchyma, as so as on its extracellular matrix, with major alterations on MMPs activities and glycosaminoglycans content. .

Contexto Colestase produz lesão hepatocelular, infiltração leucocitária, proliferação de células ductulares e fibrose do parênquima hepático por matriz extracelular. Objetivo Analisar os efeitos da ligação do ducto biliar sobre conteúdo de glicosaminoglicanos e atividade de metaloproteinases de matriz (MMP). Métodos Animais (6-8 semanas; n = 40) foram eutanasiados 2, 7 ou 14 dias após ligação do ducto biliar ou falsa ligação. A evolução da doença foi analisada por peso corporal e do fígado, concentrações séricas de bilirrubina direta, globulinas, gama glutamil transpeptidase (GGT), fosfatase alcalina (Alk-P), alanina e aspartato aminotransfesases (ALT e AST), alterações teciduais de mieloperoxidase e metaloproteinases (MMP-9, pro MMP-2 e MMP-2), histopatologia e conteúdo de glicosaminoglicanos. Resultados A colestase causou dano celular com elevação dos níveis séricos de globulinas, GGT, Alk-P, ALT e AST. Houve também infiltração leucocitária observada pelo aumento na atividade de mieloperoxidase nos grupos 7 (P = 0,0064) e 14 dias (P = 0,0002) o que leva ao aumento das lesões no tecido. Ligação do ducto biliar aumentou as atividades de pro MMP-2 (P = 0,0677), MMP-2 (P = 0,0003) e MMP-9 (P<0,0001) aos 14 dias indicando remodelamento da matriz e estabelecimento de processo inflamatório. Animais com ligação do ducto biliar mostraram um aumento do conteúdo de dermatam sulfato e/ou heparam sulfato refletindo a produção de matriz extracelular e aumento de mitose devido a depleção do parênquima hepático. Conclusões Colestase causou várias mudanças no parênquima hepático de ratos, bem como em sua matriz extracelular, com importantes alterações na atividade ...

Effect of vitamin K1 supplementation on left colon healing in rats with extrahepatic biliary obstruction

PURPOSE: To evaluate the effects of vitamin K1 on wound healing in the left colon of rats with experimental biliary obstruction. METHODS: Sixteen male rats, divided into four groups of four animals each (L, M, LK, and MK), underwent colostomy followed by bowel suture in the left colon. Seven days before, animals in the L and LK groups had undergone common bile duct ligation. The animals in groups MK and LK received vitamin K1 supplementation. On day 7 after bowel suture, repeat laparotomy was performed for evaluation of colonic healing by burst pressure measurement and collection of samples for histopathological analysis. Changes in body weight were evaluated in the four groups. RESULTS: Weight loss was lower in animals supplemented with vitamin K. No significant differences were observed in burst pressure among the four groups (p>0.05). Histological analysis showed more hemorrhage and congestion in the biliary obstruction groups. Supplemented animals exhibited increased collagen formation and less edema and abscess formation. CONCLUSION: Vitamin K supplementation attenuated weight loss and improved colonic wound healing in rats. .

Morphological changes in the liver and kidneys of rats subjected to terminal ileum exclusion during obstructive cholestasis

PURPOSE: To investigate the effects of ileal exclusion on hepatic and renal morphology in extra-hepatic cholestasis. METHODS: Twenty four rats were distributed into three groups. Group 1 (control) underwent laparotomy and laparorrhaphy. The animals in groups 2 and 3 underwent hepatic duct ligature and kept in cholestasis for four weeks. After this period, the rats in groups 2 and 3 underwent internal biliary derivation. In Group 3, the last ten centimeters of the terminal ileum were by passed and excluded. Four weeks later, histological and biochemical analysis were performed in all animals of the three groups. RESULTS: In Group 1, no abnormalities regarding hepatic morphology were observed. All animals from groups 2 and 3 presented hepatic fibrosis. No difference was observed between the two groups. No morphological differences in renal histology could be identified among the three groups. There were differences in AST (p<0.05), ALT (p<0.05), direct bilirubin (p<0.05), ƔGT (p<0.05), urea (p<0.05) and creatinine (p<0.05) in Group 3 compared to control. CONCLUSION: The distal ileum exclusion had no influence upon the hepatic and renal morphological alterations, and biochemical liver and kidney tests have worsened. .

Influence of distal ileum exclusion on hepatic and renal functions in presence of extrahepatic cholestasis / Influência da exclusão do íleo terminal nas funções hepáticas e renais em presença de colestase extra-hepática

OBJECTIVE: To verify whether the ileal exclusion interferes with liver and kidney functional changes secondary to extrahepatic cholestasis. METHODS: We studied 24 rats, divided into three groups with eight individuals each: Group 1 (control), Group 2 (ligation of the hepatic duct combined with internal biliary drainage), and Group 3 (bile duct ligation combined with internal biliary drainage and exclusion of the terminal ileum). Animals in Group 1 (control) underwent sham laparotomy. The animals of groups 2 and 3 underwent ligation and section of the hepatic duct and were kept in cholestasis for four weeks. Next, they underwent an internal biliary bypass. In Group 3, besides the biliary-enteric bypass, we associated the exclusion of the last ten centimeters of the terminal ileum and carried out an ileocolic anastomosis. After four weeks of monitoring, blood was collected from all animals of the three groups for liver and kidney biochemical evaluation (albumin, ALT, AST, direct and indirect bilirubin, alkaline phosphatase, cGT, creatinine and urea). RESULTS: there were increased values of ALT, AST, direct bilirubin, cGT, creatinine and urea in rats from Group 3 (p < 0.05). CONCLUSION: ileal exclusion worsened liver and kidney functions in the murine model of extrahepatic cholestasis, being disadvantageous as therapeutic procedure for cholestatic disorders. .

OBJETIVO: verificar se a exclusão ileal interfere nas alterações funcionais hepáticas e renais, secundárias à colestase extra-hepática. MÉTODOS: foram estudados 24 ratos, distribuídos em três grupos (n=8): Grupo 1 (controle), Grupo 2 (ligadura do ducto hepático combinada com drenagem biliar interna) e Grupo 3 (ligadura do ducto hepático combinada com drenagem biliar interna e exclusão do íleo terminal). Os animais do Grupo 1 (controle) foram submetidos a laparotomia e laparorrrafia. Os animais dos grupos 2 e 3 foram submetidos a ligadura e secção do ducto hepático e mantidos em colestase por oclusão biliar durante quatro semanas. A seguir, foram submetidos a derivação biliar interna. No Grupo 3, associou-se a exclusão dos últimos dez centímetros do íleo terminal e anastomose ileocólica à derivação biliodigestiva. Após outras quatro semanas de acompanhamento, foi colhido sangue de todos os animais dos três grupos, para avaliação bioquímica do fígado e dos rins (albumina, ALT, AST, bilirrubinas direta e indireta, fosfatase alcalina, cGT, creatinina e ureia). RESULTADOS: houve aumento dos valores de ALT, AST, bilirrubina direta, cGT, creatinina e ureia nos ratos do Grupo 3 (p < 0,05). CONCLUSÃO: no modelo murino de colestase extra-hepática, a exclusão ileal piorou as funções hepáticas e renais, sendo desvantajosa como proposta terapêutica para afecções colestáticas. .

Evaluation of various causes and treatment of obstructive jaundice at Liaquat university hospital

The purpose of this study is to evaluate various causes of obstructive jaundice and its available treatment modalities in this area. Descriptive study. This study was conducted at Liaquat University Hospital Hyderabad/Jamshoro from January 2010 to december 2010. All the patients above 15 years of both sexes were included in this study having obstructive jaundice diagnosed on the basis of clinical grounds and supported by LFT and ultrasonography. A uniform system of history taking, physical examination, investigation and treatment was adopted for all the patients and information was recorded on the pre-designed proforma. Comprises 80 cases of obstructive jaundice, average age was 50 years with the female to male ratio1.5:1. The most common cause was carcinoma of head of pancreas in 27 [33.75%] followed by bile duct stone disease in 24 [33%] cases of carcinoma of gallbladder were in females. Jaundice with weight loss, itching [46%] and mass [28%] were the presenting features in malignant obstruction while pain [83.33%] and fever [25%] was mostly seen in patient with choledocholithiasis. Gallbladder was palable in malignant obstruction only. Anemia was the common associated problem [60%] especially in malignant cases [83%] only biopsy was preferred in 30 [37.50%] of cases, while choledochoduodenustomy in 14 [17.5%]. Postoperative complications were only in 28 [35%] of patients with wound sepsis in 17 [11.25%]. The mortality rate was [11.25%]. Maximal survival for carcinoma of pancreas was 9 months. The average post operative stay was 12 days. Cholecystectomy with supraduodental choledochotomy and T-tube insertion is effective treatment for bile duct stones whereas internal drainage of billary system is good for advanced malignant cases

Hemangioma capilar como causa de colestasis extrahepática: reporte de caso / Capillary hemangioma as cause of extrahepatic cholestasis: case report

El hemangioma capilar es una patología epitelial benigna que se presenta usualmente en la piel, sin embargo también puede presentarse en mucosas, hasta el momento en la literatura revisada no hay reportes de hemangiomas capilares como causa de colestasis extrahepáticas. Se reporta el caso de un paciente femenino de 35 años con clínica de colestasis extrahepática sin evidencias de lesiones ocupantes de la luz de las vías biliares, se le realiza duodenoscopia donde se evidencia lesión de aspecto adenomatoso a nivel de la papila de Vater, la cual es resecada. El reporte anatomopatológico concluye la lesión como un hemangioma capilar. En vista de que en la literatura no se encuentran reportes de hemangiomas capilares como etiologías de colestasis se decide reportar dicho hallazgo

The capillary hemangioma is a benign epithelial disease usually occurs in the skin, but can also occur in mucous membranes, so far in the literature there are no reports of capillary hemangiomas as a cause of extrahepatic cholestasis. We report the case of a female patient 35 years old, with clinical signs of extrahepatic cholestasis and no evidence of occupying lesions of the bile ducts, duodenoscopy was performed which revealed a lesion of adenomatous aspect of the papilla of Vater, which is resected and sent to pathology. The report from pathology was of a capillary hemangioma. Since in the literature are no reports of capillary hemangiomas as etiologies of cholestasis is decided to report this finding

A Case of Adenocarcinoma in situ of the Distal Common Bile Duct Diagnosed by Percutaneous Transhepatic Cholangioscopy

Extrahepatic cholangiocarcinoma is often clinically challenging to diagnose. Even multidisciplinary approaches which include computed tomography, magnetic resonance imaging, and endoscopic retrograde cholangiography are unsatisfactory in some cases, especially with biliary stricture. Percutaneous transhepatic cholangioscopy (PTCS) with its direct visualization for biopsy appears to be a promising technique for detecting cholangiocarcinoma at an early stage. We report a case of adenocarcinoma in situ of the distal common bile duct (CBD) that was confirmed by PTCS. This case suggests the useful role of PTCS in the differential diagnosis of a distal CBD obstruction, particularly when other diagnostic modalities do not provide definitive information.

Ascariasis hepatobiliar: informe de caso / Hepatobiliary ascariasis: a case report

Introducción. La ascariasis hepática es la complicación menos frecuente de la infección parasitaria por el helminto intestinal Ascaris lumbricoides. Sin embargo, el cuadro de ascariasis biliar complicada con abscesos hepáticos se observa en ciertas zonas endémicas como América Latina y el Sudeste Asiático, donde debe ser un diagnóstico a considerar en pacientes con sintomatología biliar obstructiva, principalmente en niños, ya que por el tamaño pequeño de sus órganos tienen mayor probabilidad de desarrollar obstrucción. Este gusano tiene la habilidad de entrar en ductos, como la vía biliar intra y extrahepática, y al morir dentro de la misma provoca serias complicaciones como obstrucción, colangitis y abscesos secundarios. Caso clínico. Se presenta el caso de una niña de 6 años de edad con antecedente de Síndrome de Down, desnutrición proteico-calórica crónica grado II y nivel socioeconómico bajo, que se presentó con historia de fiebre diaria no cuantificada, tos seca, dolor abdominal y hepatomegalia dolorosa de dos semanas de evolución. Se realizó ultrasonido abdominal donde se encontraron múltiples abscesos hepáticos con A. lumbricoides en hígado y vía biliar. La paciente desarrolló un choque séptico sin respuesta al tratamiento instaurado y falleció a los 30 días intrahospitalarios. Conclusiones. La ascariasis hepatobiliar, aunque rara, es más común en países endémicos y tiene una alta morbi-mortalidad si no se diagnostica y se instaura el manejo adecuado tempranamente. Es imperativo que los médicos hondureños conozcan esta parasitosis para que con un adecuado manejo contribuyan a disminuir la mortalidad, principalmente infantil, por esta causa. Es necesario implementar medidas de prevención y control eficaces para las geohelmintiasis en Honduras...

Síndrome de Mirizzi: estudo de 11 casos / Mirizzis syndrome: report of eleven cases

Objetivo: descrever série de onze pacientes com síndrome de Mirizzi, submetidos a tratamento cirúrgico, comentando os aspectos etiopatogênicos e apresentação clínica, com ênfase no diagnóstico e tratamento. Métodos: estudo retrospectivo de onze pacientes consecutivos submetidos a tratamento cirúrgico. Foram considerados para apreciação: aspectos demográfico, clínicos, laboratoriais, meios diagnósticos, achados intraoperatórios, classificação dos doentes de acordo com Csendes et al., tática cirúrgica empregada e evolução pós-operatória. Resultados: dez pacientes (91,0%) eram mulheres e um (9,0%) homem. Os seguintes sintomas foram observados: dor e icterícia em todos os pacientes, colúria em nove (81,0%), náuseas e vômitos em sete (63,0%), acolia fecal em cinco (45,0%) e tumor palpável em um (9,0%). Os exames de laboratório mostraram leucocitose igual ou superior a 15.000 /mm3 em 45,0%. A bilirrubina total variou de 3,1 a 19,0 mg/dl. A ultrassonografia feita em todos pacientes mostrou presença de colelitíase e dilatação de V.B. em 77,7% e vesícula escleroatrófica em 27,0%. A tomografia computadorizada abdominal foi realizada em 9,0% e colangiopancreatografia em 18,0%. Os casos foram classificados, segundo Csendes, em: tipo I (quatro), tipo II (dois), tipo III (três) e tipo IV (dois) pacientes. Todos foram operados por cirurgia convencional. Destes, quatro (36,0%) apresentavam colangite, sendo três (27,0%) operados na urgência e um outro evoluiu com colangite durante a investigação, sendo operado no 19 dia. Os demais foram internados e operados eletivamente. Realizou-se: colecistectomia e derivação biliodigestiva em seis pacientes (54,0%), colecistectomia e coledocotomia em três (27,0%) e colecistectomia simples em dois casos (18%). No pós-operatório, nove (82,0%) evoluíram bem e tiveram alta hospitalar. Dois pacientes (18,0%) foram a óbito. Conclusões: todos os pacientes apresentavam sinais e sintomas de icterícia obstrutiva e em quase metade o hemograma era infeccioso. Apenas em três casos houve suspeita diagnóstica no pré-operatório. Os pacientes estáveis, sem infecção, que permitiram melhor investigação evoluíram favoravelmente. O tratamento da síndrome de Mirizzi é cirúrgico, variando a tática de acordo com o tipo da lesão.

Objectives: to report a series of eleven patients with Mirizzis syndrome submitted to surgical treatment. The authors present the etiopathogenic and clinical aspects of the disease. Methods: retrospective study of the eleven patients consecutive submitted to surgical treatment. The authors analysed the demografic, clinical and laboratory data, as well as intraoperative findings. They also classified the lesion according to Csendes classification, and presented the surgical management and post-operative follow-up. Results: there were 10 female patients (91.0 %) and 1 male patient (9.0%). Symptoms and signs were diffuse upper abdominal pain and jaundice in all patients, choluria in 9 (81%), nausea and vomit in 7 (63%), fecal acholia in 5 (45.0%) and a palpable tumor in 1 patient (9.0%). The laboratory exams showed leucocytosis equal or superior to 15.000/mm³ (45%) and the plasma bilirrubin varied between 3.1 mg/dL and 19.0 mg/dL. Ultrasonography showed in all patients the presence of cholelithiasis. There was dilation of gallbladder in 77.5% of the cases and scleroatrophic gallbladder in 27.0% patients. CT scan was realized in 9.0% and cholangiopancreatography in 18% of patients. The cases were classified according to Csendes classification. There were four type I, two type II, three type III and two type IV. All eleven cases were managed by classical open technique. Four patients (36%) presented with cholangitis; three of these patients had emergency operations and one presented cholangitis during the workup investigation, being operated on day 19 of admission. The others had elective operations. The surgical operations were: cholecystectomy and biliodigestive deviation in 6 patients (54%), cholecystectomy and choledochotomy in 3 patients (27%) and only cholecystectomy in 2 patients (18%). The postoperative course was uneventful in 9 patients (82%), but 2 patients (18%) died. Conclusion: all patients presented symptoms and signs of obstructive jaundice, and nearly half of these had infectious hemogram. The diagnosis of Mirizzis syndrome was suspected in only three patients. A complete diagnostic investigation was possible only in stable patients without infection, and these patients had a favorable course. Treatment of Mirizzis syndrome is surgical and the choice of operative approach varies according to the type of lesion.

Effects of albumin administration in serum liver enzymes of rats in the presence of extrahepatic biliary obstruction / Efeitos da administração de albumina nos níveis séricos de enzimas hepáticas em ratos com obstrução biliar extra-hepática

PURPOSE: To study the influence of albumin on changes of liver function in the extrahepatic biliary obstruction through an experimental model in rats. METHODS: Sixty rats were divided into four groups: Group C (Control): 6 animals. Group M (Fictitious Operation): 18 rats underwent laparotomy and handling of the bile ducts; Groups O (extrahepatic biliary obstruction) and A (Treated with 2 percent albumin): 18 animals in each group underwent ligation of the ductus liver; The animals in groups M, O and A were divided into three subgroups of 6 animals each to be killed in the 7, 14 and 21 days postoperative (POD). Blood was drawn for determination of total bilirubin (TB), indirect bilirubin (IB), direct bilirubin (DB), alkaline phosphatase (ALP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT). RESULTS: On POD 7, BI levels were 4.5 mg / dl in group O and 2.1 mg / dl in group A (p = 0.025). On the 14th POD, the levels of PA were 1185.2 U / l in the group and O 458.3 U / l in group A (p = 0.004). ALT levels were 101.7 U / l in the group O and 75.7 U / l in group A (= 0.037). On POD 21, the levels of ALP were 1069.5 U / l in the group O and 468.3 U / l in group A (p = 0, 004). CONCLUSION: The administration of albumin reduced the serum levels of bilirubin in the 7th day of supplementation.
