Predictors of Jaundice Resolution and Survival After Endoscopic Treatment of Primary Sclerosing Cholangitis. Hepatol Commun 2021; 6:809-820. [PMID: 34558848 PMCID: PMC8948596 DOI: 10.1002/hep4.1813] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 06/28/2021] [Accepted: 07/12/2021] [Indexed: 12/15/2022] Open
Abstract
The benefit of endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of primary sclerosing cholangitis (PSC) remains controversial. To identify predictors of jaundice resolution after ERCP and whether resolution is associated with improved patient outcomes, we conducted a retrospective cohort study of 124 patients with jaundice and PSC. These patients underwent endoscopic biliary balloon dilation and/or stent placement at an American tertiary center, with validation in a separate cohort of 102 patients from European centers. Jaundice resolved after ERCP in 52% of patients. Median follow‐up was 4.8 years. Independent predictors of jaundice resolution included older age (P = 0.048; odds ratio [OR], 1.03 for every 1‐year increase), shorter duration of jaundice (P = 0.059; OR, 0.59 for every 1‐year increase), lower Mayo Risk Score (MRS) (P = 0.025; OR, 0.58 for every 1‐point increase), and extrahepatic location of the most advanced biliary stricture (P = 0.011; OR, 3.13). A logistic regression model predicted jaundice resolution with area under the receiver operator characteristic curve of 0.67 (95% confidence interval, 0.5‐0.79) in the validation set. Independent predictors of death or transplant during follow‐up included higher MRS at the time of ERCP (P < 0.0001; hazard ratio [HR], 2.33 for every 1‐point increase), lower total serum bilirubin before ERCP (P = 0.031; HR, 0.91 for every 1 mg/dL increase), and persistence of jaundice after endoscopic therapy (P = 0.003; HR, 2.30). Conclusion: Resolution of jaundice after endoscopic treatment of biliary strictures is associated with longer transplant‐free survival of patients with PSC. The likelihood of resolution is affected by demographic, hepatic, and biliary variables and can be predicted using noninvasive data. These findings may refine the use of ERCP in patients with jaundice with PSC.

Abstract
Primary sclerosing cholangitis (PSC) is a rare progressive cholangitis resulting in cirrhosis and cholangiocellular carcinoma. The pathogenesis is unclear and an effective medical therapy is not available. It is highly associated to ulcerative colitis for which recently a disturbance of the tight junction (TJ) barrier has been claimed as etiologic feature. Genetic mouse models with intestinal TJ disruption showed a defective transport of phosphatidylcholine (PC) to intestinal mucus. Consequently, an ulcerative colitis phenotype developed. In the present study we evaluate whether there is also a paracellular transport of PC through TJ to the apical side of cholangiocytes. As in ulcerative colitis, a TJ defect could lead to deficient PC in biliary mucus. It would impair the protective barrier against aggressive bile acids in bile. Indeed with polarized biliary tumor cells a vectorial transport of PC from basal to luminal side was demonstrated using a transwell culture system. PC was not taken up by the cells but moved paracellularly via TJ to the apical side driven by luminal HCO3- generated by the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) and the anion exchange protein 2 (AE2). If such a TJ-mediated PC translocation to the apical surface of cholangiocytes could be disrupted in a genetic mouse model, a PSC phenotype would be expected. With such an experimental model functional operative therapies can be evaluated. We propose that disruption of TJ mediated paracellular transport of PC to the apical side of cholangiocytes could lead to biliary mucus PC depletion. This may be a pathogenetic factor for development of PSC.

Predictive criteria of response to endoscopic treatment for severe strictures in primary sclerosing cholangitis. Clin Res Hepatol Gastroenterol 2019; 43:387-394. [PMID: 30772328 DOI: 10.1016/j.clinre.2019.01.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Revised: 12/17/2018] [Accepted: 01/10/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND The aim of this study was to identify predictive criteria of improvement after endoscopic treatment (ET) for severe strictures of extrahepatic bile ducts in patients with primary sclerosing cholangitis (PSC). METHODS PSC patients who had at least one ET for severe stricture were included. Features of magnetic resonance cholangiography (MRC), performed before ET, were evaluated according to a standard model of interpretation, and a radiologic qualitative score of probability of improvement after ET was built. Score 3 (likely) was given in case of severe common bile duct (CBD) stricture with marked dilatation without severe strictures of upstream ducts, Score 1 (unlikely) was given in case of severe multiple strictures of secondary ducts without biliary dilatation and Score 2 (undeterminate) was given to an intermediate pattern. The response to ET was assessed at 2 months (T2-response) from the last ET and at 12 months (T12-response) from inclusion. RESULTS Thirty-one patients were included. All had severe stricture (reduction ≥ 75% of the diameter) of CBD and 50% had severe stricture of right and/or left hepatic duct (LHD) at MRC before ET. According to the qualitative score, 16 patients had Score 3, 7 had Score 1 and 9 had Score 2. T12-response was obtained in 50% of patients. In univariate analysis, short LHD strictures, bilirubin, transaminases, pruritus and Score 3 were associated with T12-response. Increased bilirubin and transaminases were independent predictive factors of T12-response (HR 24, 95% CI: 3.4-170.4, P = 0.001 and 23.8, 95% CI: 3.4-169.4, P = 0.002, respectively). CONCLUSION MRC, together with biochemical features, may contribute to identify the PSC patients who are likely to be improved after ET for severe strictures of extrahepatic bile ducts.

Abstract
These guidelines on the management of primary sclerosing cholangitis (PSC) were commissioned by the British Society of Gastroenterology liver section. The guideline writing committee included medical representatives from hepatology and gastroenterology groups as well as patient representatives from PSC Support. The guidelines aim to support general physicians, gastroenterologists and surgeons in managing adults with PSC or those presenting with similar cholangiopathies which may mimic PSC, such as IgG4 sclerosing cholangitis. It also acts as a reference for patients with PSC to help them understand their own management. Quality of evidence is presented using the AGREE II format. Guidance is meant to be used as a reference rather than for rigid protocol-based care as we understand that management of patients often requires individual patient-centred considerations.

Abstract
Cholestatic liver diseases (CLDs) encompass a variety of disorders of abnormal bile formation and/or flow. CLDs often lead to progressive hepatic insult and injury and following the development of cirrhosis and associated complications. Many such complications are clinically silent until they manifest with severe sequelae, including but not limited to life-altering symptoms, metabolic disturbances, cirrhosis, and hepatobiliary diseases as well as other malignancies. Primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC) are the most common CLDs, and both relate to mutual as well as unique complications. This review provides an overview of PSC and PBC, with a focus on preventive measures aimed to reduce the incidence and severity of disease-related complications.

Abstract
Dominant strictures (DSs) of the biliary tree occur in approximately 50% of patients with primary sclerosing cholangitis (PSC) and may cause significant morbidity. Nevertheless, the definition and management of DSs lacks consensus. We aimed to better understand current perceptions and practices regarding PSC‐associated DSs. We conducted an anonymous, 23‐question, survey‐based study wherein electronic surveys were distributed to 131 faculty in the Division of Gastroenterology and Hepatology at the three Mayo Clinic campuses (Rochester, Scottsdale, and Jacksonville) as well as the affiliated practice network. Responses were aggregated and compared, where applicable, to practice guidelines of the American Association for the Study of Liver Diseases and European Association for the Study of the Liver. A total of 54 faculty (41.2%) completed the survey, of whom 24 (44.4%) were hepatologists, 21 (38.9%) gastroenterologists, and 9 (16.7%) advanced endoscopists. One of the major study findings was that there was heterogeneity among participants' definition, evaluation, management, and follow‐up of DSs in PSC. The majority of participant responses were in accordance with societal practice guidelines, although considerable variation was noted. Conclusion: Despite the prevalence and morbidity of DSs in PSC, clinical perceptions and practices vary widely among hepatologists, gastroenterologists, and advanced endoscopists who manage these patients, even within a single health care system. Further studies are needed to address these variations, develop general and evidence‐based consensus, and increase adherence to societal guidelines. (Hepatology Communications 2018;2:836‐844)

Abstract
Sclerosing cholangitis and cholestatic jaundice secondary to metastatic disease is a rare complication. We report a rare case of secondary sclerosing cholangitis (SSC) due to lymphatic spread from ovarian cancer with complete resolution after chemotherapy. The diagnosis of SSC from metastatic ovarian cancer was clinically challenging, as endoscopic retrograde cholangiopancreatography revealed irregular hepatic ducts consistent with sclerosing cholangitis, but it did not identify any malignant cells. The final diagnosis was made with liver biopsy revealing high-grade metastatic Mullerian carcinoma. The patient responded well to chemotherapy and is in remission. A timely diagnosis is important and can lead to complete resolution of the disease.

Abstract
Primary sclerosing cholangitis is a chronic cholestatic liver disease that can shorten life and may require liver transplantation. The cause is unknown, although it is commonly associated with colitis. There is no approved or proven therapy, although ursodeoxycholic acid is used by many on an empiric basis. Complications including portal hypertension, fat-soluble vitamin deficiency, metabolic bone diseases, and development of cancers of the bile duct or colon can occur.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic and progressive cholestatic liver disease that often leads to the development of cirrhosis. Complications of PSC include pruritus, fatigue, vitamin deficiencies, metabolic bone disease, dominant biliary strictures, gallstones, and hepatobiliary malignancies, most commonly cholangiocarcinoma (CCA). Despite the presumed autoimmune etiology of PSC, a clear benefit from immunosuppressive agents has not yet been established, and their use is limited by their side effects. Endoscopy is required in evaluation of biliary strictures in PSC to rule out the possibility of CCA. Liver transplantation is currently the only life-extending therapy for patients with end-stage disease. However, disease recurrence can be a source of morbidity and mortality as transplanted patients survive longer. Further studies are needed to develop an optimal therapeutic strategy for patients with PSC to decrease the incidence of complications of the disease, to decrease the need for transplantation, and to extend life expectancy.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic immune-mediated disease of the liver of unclear etiology, characterized by chronic inflammation and fibrosis of bile ducts. It primarily affects middle-aged men and is associated with 4-fold increased mortality as compared with an age- and sex-matched population. Progressive biliary and hepatic damage results in portal hypertension and hepatic failure in a significant majority of patients over a 10- to 15-year period from the initial diagnosis. In addition, PSC confers a markedly increased risk of hepatobiliary cancer, including cholangiocarcinoma and gallbladder cancer, as compared with the general population, and cancer is the leading cause of mortality in patients with PSC. It is associated with inflammatory bowel disease in 70% of patients and increases the risk of colorectal cancer almost 10-fold. Despite significant research efforts in this field, the pathogenic mechanisms of PSC are still incompletely understood, although growing evidence supports the role of genetic and immunologic factors. There are no proven medical therapies that alter the natural course of the disease. Thus, liver transplantation is the only available treatment for patients with advanced PSC, with excellent outcomes in this population.

Abstract
Several hepatobiliary abnormalities have been described in association with inflammatory bowel disease (IBD), including primary sclerosing cholangitis (PSC), small duct PSC, chronic hepatitis, cryptogenic cirrhosis, cholangiocarcinoma, and cholelithiasis. PSC is the most common biliary condition in patients with IBD, with an incidence ranging from 2.5% to 7.5%. PSC usually progresses insidiously and eventually leads to cirrhosis independent of inflammatory bowel disease activity. There is a very high incidence of cholangiocarcinoma and an elevated risk for developing colon cancer in patients with PSC. Medical therapy has not proven successful in slowing disease progression or prolonging survival. Treatment of symptoms due to cholestasis, such as pruritis and steatorrhea, is an important aspect of the medical care of patients with PSC. Our preferred treatment of pruritis due to cholestasis is with bile acid binding exchange resins, such as cholestyramine or colestipol. Endoscopic manipulation is recommended for treating complications of recurrent cholangitis or worsening jaundice in the setting of a dominant stricture, but endoscopic approaches have not been conclusively demonstrated to improve survival or decrease the need for liver transplantation. Liver transplantation remains the only effective treatment of advanced PSC, and should be considered in patients with complications of cirrhosis or intractable pruritis or fatigue.

Abstract
BACKGROUND Primary sclerosing cholangitis (PSC) remains a challenging disease to manage. The main goals are prevention of disease progression and reduction of the increased cancer risk. AIMS To review the management strategies for PSC and its variant forms based on published studies. METHODS Publications were identified using Pubmed, Medline and Ovid search engines. RESULTS Distinguishing PSC from variants, such as IgG4-associated cholangitis, and overlap with autoimmune hepatitis is essential to guide treatment decisions. There is no proven efficacious medical treatment for PSC. Ursodeoxycholic acid has been disappointing in low and moderate doses, and potentially dangerous in higher doses, although its role and optimal dose in chemoprevention requires investigation. The novel bile acid, 24-norursodeoxycholic acid, has shown promise in mouse models; human trials are in progress. Dominant strictures are optimally managed by dilatation and stenting to relieve obstructive complications, although exclusion of biliary malignancy is essential. Liver transplantation is the only proven therapy for those with advanced disease. Cholangiocarcinoma remains the most unpredictable and feared complication. In highly selected groups, neo-adjuvant chemoradiation with liver transplantation seems promising, but requires further validation. Screening for inflammatory bowel disease and surveillance for colorectal carcinoma should not be overlooked. CONCLUSIONS The effective management of PSC and its variants is hindered by uncertainties regarding pathogenesis of disease and factors responsible for its progression. Genome studies may help to identify further targets for drug therapy and factors leading to malignant transformation.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, progressive, cholestatic liver disease characterized by inflammation and fibrotic obliteration of the hepatic biliary tree. It is commonly associated with inflammatory bowel disease (IBD). A number of complications can occur which require special consideration, the most important of which is the development of cholangiocellular carcinoma (CCC). Unfortunately, no medical therapy is currently available for the underlying liver disease. Liver transplantation is an effective, life-extending option for patients with advanced PSC. Geographical variations between East and West include a second peak for age with a lower association with IBD in a Japanese population and female predominance in a lone study from Turkey. The clinical and biochemical Mayo criteria may not be universally applicable, as different patients show variations regarding the initial presentation and natural course of the disease. Directing research towards explaining these geographical differences and understanding the pathogenesis of PSC is required in order to develop better therapies for this devastating disease.

Abstract
GOALS The current study presents 1 tertiary endoscopy center's 20-year experience using endoscopic therapy to treat patients with symptomatic primary sclerosing cholangitis (PSC). BACKGROUND Endoscopic therapy for patients with PSC and dominant strictures has been used for more than 20 years, but there is concern that instrumenting a sclerotic biliary tree induces risks that outweigh anticipated benefits. STUDY In this retrospective chart review, 117 patients with PSC were identified using ICD-9 codes. Patients had a mean age of 47 years (range: 15 to 86 y). Mean duration of follow-up was 8 years (range: 2 to 20 y). Of the 117 identified patients, 106 underwent endoscopic retrograde cholangiopancreatography on one or more occasions (for a total of 317 endoscopic retrograde cholangiopancreatographies), and a subset of 84 patients received endoscopic therapy for treatment of dominant strictures and/or deteriorating clinical status. Actual survival for endoscopically treated patients was compared with predicted survival using the Mayo Clinic natural history model for PSC. RESULTS Our chart review revealed 23 recognized complications among the 317 procedures performed (7.3%), and no procedure-related deaths. Observed patient survival at years 3 and 4 was significantly higher than that predicted by the Mayo Clinic natural history model for PSC (P=0.021). CONCLUSIONS Patients with PSC who have a deteriorating clinical course benefited from endoscopic therapy to provide drainage of bile ducts, removal of stones, and/or temporary relief from obstructions, with acceptable procedure-related complications and higher than expected 3-year and 4-year survival.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease, characterized by progressive inflammation and fibrosis of the bile ducts, resulting in biliary cirrhosis and is associated with a high risk of cholangiocarcinoma. The majority of patients are young, male and have coexisting inflammatory bowel disease. PSC is found with a prevalence of 10/100,000 in Northern European populations. The pathophysiology of PSC is a complex multistep process including immunological mechanisms, immunogenetic susceptibility and disorders of the biliary epithelia. The diagnosis is primarily based on endoscopic cholangiography although magnetic resonance imaging is increasingly used; biochemistry and immunoserology as well as histology play only a minor role. Due to the high risk of developing cholangiocarcinoma and also other tumours of the GI tract, surveillance strategies are essential, however they have yet to be established and evaluated. Biochemical parameters, clinical risk factors, endoscopic procedures and imaging techniques contribute to the early identification of patients at risk. Since medical therapy of PSC with ursodeoxycholic acid does not improve survival, to date, liver transplantation is the only option with a cure potential; if transplantation is accurately timed, transplanted PSC patients have an excellent rate of survival. However if cholangiocarcinoma is detected, a curative treatment is not possible in the majority of cases. The present review critically summarizes the current knowledge on the aetiopathogenesis of PSC and gives an overview of the diagnostic approaches, surveillance strategies and therapeutic options. Primary sclerosing cholangitis is a disease of unknown aetiology and without any further curative treatment options apart from liver transplantation. Therefore it may be regarded as the greatest challenge in hepatology today.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic, cholestatic liver condition characterized by progressive fibrosis and destruction of the intra- and extrahepatic biliary tree. PSC has a clear association with inflammatory bowel disease and is often progressive, leading to cirrhosis and end-stage liver failure. For many patients, liver transplantation offers the only hope of long-term survival. No effective medical treatment exists, and therapy is often aimed at treating complications of the disorder, including dominant biliary strictures, which may cause symptomatic jaundice, cholangitis, and pruritus. Studies on endoscopic therapy (eg, biliary dilation and/or stent insertion) have shown favorable results, although most studies have been small, retrospective, and uncontrolled. Up to 20% of patients with PSC develop cholangiocarcinoma; however, distinguishing between cholangiocarcinoma and benign strictures can be difficult. Ideally, randomized trials are required to determine the safest and most effective endoscopic management for symptomatic dominant strictures.

Abstract
BACKGROUND The diagnosis of primary sclerosing cholangitis (PSC) is reached by typical cholangiographic findings and liver biopsy. The characteristic cholangiographic abnormalities consist of multifocal strictures and dilatations in the intrahepatic and/or extrahepatic bile ducts. Patients may develop cirrhosis and portal hypertension. Endoscopy may reveal esophageal/gastric varices and portal hypertensive gastropathy. OBJECTIVE To define a novel endoscopic finding in patients with PSC. DESIGN Case series. SETTING Single tertiary referral center in Turkey. PATIENTS Ten patients with PSC, 16 with liver cirrhosis, and 10 with PSC-like cholangiogram. INTERVENTIONS Inspection of papilla with duodenoscope and ERCP. MAIN OUTCOME MEASUREMENTS Retraction of papilla into the duodenum wall. RESULTS Ten patients with PSC (8 male, 2 female, mean age 38 y) underwent ERCP at our institution. Retraction of papilla into the duodenum wall was observed in 7 patients (70%). The mean time elapsed between the retraction of the papilla and onset of PSC was 5.1 years (range 2-7 y). In patients with retraction of the papilla, both of the intrahepatic and extrahepatic bile ducts were involved; however, only the intrahepatic bile ducts were involved in patients with no retraction of papilla. Of 7 patients with retraction of papilla, 5 had a history of sphincterotomy procedure 5.4 years previously (range 5-6 y). Two patients had native papilla. None of the patients had end stage liver disease. Retraction of papilla was observed in none of the 16 patients with cirrhosis of the liver and in 10 with PSC-like cholangiogram. LIMITATIONS Only observational; absence of surgical and/or pathologic evidence. CONCLUSIONS Papilla may be embedded in the duodenum wall in some patients with PSC. Extrahepatic involvement seems to be necessary for the occurrence of this finding.

Abstract
Primary sclerosing cholangitis (PSC) is a rare but important liver disease that leads to cirrhosis and need for liver transplantation in a high proportion of cases. The disease occurs in approximately 1 per 100,000 population per year, usually presents in adulthood, and affects men more often than women. Typical serum biochemical results, autoantibodies and liver biopsy are suggestive but not diagnostic of PSC, the diagnosis requiring cholangiographic demonstration of stricturing and dilatation of the intra- and/or extra-hepatic bile ducts. The natural history of PSC is variable, the average survival being 12 to 17 years. The cause of PSC is still unknown. Although considered an autoimmune disease, PSC has several atypical features and a strong genetic component. The therapy of PSC is unsatisfactory. Standard doses of ursodeoxycholic acid (UDCA) lead to improvements in biochemical abnormalities but not in histology, cholangiographic appearance or survival. Several innovative therapies have been tried in PSC, but with scant evidence of benefit. For patients with high grade strictures, endoscopic dilatation is beneficial. Liver transplantation is successful for end-stage liver disease due to PSC and improves survival. PSC may recur after transplantation but is rarely progressive. The most dreaded complication of PSC is cholangiocarcinoma. Diagnosis of this highly malignant tumor is difficult, and there are no biomarkers for its early detection. Liver transplantation for cholangiocarcinoma has an exceedingly poor outcome, although transplantation with neoadjuvant chemoirradiation holds promise in selected patients. Thus, significant opportunities remain for basic and clinical research into the cause, natural history, and therapy of PSC.

Abstract
Primary sclerosing cholangitis (PSC) is an important cause of chronic liver disease. We review the management of PSC and report a 20-year follow-up of our initial 10 patients. This is the longest detailed follow-up of a group of PSC patients to date. We discuss the clinical course and results of endoscopic management in these patients and relate these data to management of PSC in general. We compare the actual survival of these patients to predicted survival scores based on the Mayo multicenter survival model. Although our patients presented with cholangitis, which typically reflects advanced stages of liver disease, their survival compares favorably with expected survival in unselected PSC patients. Endoscopic balloon dilation of PSC patients presenting with biliary strictures and cholangitis may have long-term benefit in addition to short-term symptomatic relief.

Abstract
OBJECTIVES Assess the role of cholangioscopy in primary sclerosing cholangitis for 1) detection of cholangiocarcinoma using cholangioscopy-assisted biopsy 2) detection of stones not seen on cholangiography 3) stone removal with cholangioscopy-directed lithotripsy. METHODS Prospective cohort of consecutive patients referred for cholangioscopy to evaluate dominant strictures or stones. A data collection sheet was employed. Follow-up was by chart review/phone contact. Clinical improvement was defined as resolution of jaundice or > or =50% reduction in pain or cholangitis episodes requiring hospitalization. RESULTS 41 patients (30M, 11F) had 60 cholangioscopy procedures (55 per oral, 5 percutaneous). 33/41 (80%) patients underwent 44 tissue sampling events. HISTOLOGY positive for extrahepatic cholangiocarcinoma (N = 1), negative/atypical (N = 31), and inadequate (N = 1). Stones were found in 23/41 (56%) patients, of which 7/23 (30%) were missed on cholangiography and detected only by cholangioscopy. 9/23 (39%) underwent cholangioscopy-directed lithotripsy. Stone clearance: complete (N = 10, 7 by cholangioscopy-directed lithotripsy after failed conventional stone extraction); partial (N = 7); and not attempted (N = 6). Median follow-up was 17.0 months (range 1-56). Clinical improvement was achieved in 25/40 (63%). Eight patients have undergone transplant and cholangiocarcinoma was present in the explant of two at 1 and 12 months post-cholangioscopy, respectively. CONCLUSIONS This is the first series of patients with primary sclerosing cholangitis undergoing cholangioscopy for the evaluation of dominant strictures and cholangioscopy-directed stone therapy with demonstrable clinical benefits. Stones detected by cholangioscopy were missed by cholangiography in nearly one of three patients. Cholangioscopy-directed lithotripsy may be superior to conventional ERCP for achieving complete stone clearance. Despite the use of cholangioscopy, diagnosis of cholangiocarcinoma remains technically challenging.

Abstract
The most common biliary problem in patients with inflammatory bowel disease is primary sclerosing cholangitis (PSC). The treatment of this disease is multifaceted and frequently requires a multidisciplinary approach involving internists, nutritionists, gastroenterologists, and surgeons. Unfortunately, other than liver transplantation, no therapy that is currently available has been proven to alter the natural history of PSC or prolong survival. Ursodeoxycholic acid is currently the most promising pharmacologic treatment option for slowing disease progression and should be used in higher than usual doses (20 to 30 mg/kg/d). Treatment of symptoms due to cholestasis, such as pruritis and steatorrhea, is an important aspect of the medical care of patients with PSC. Our preferred treatment of pruritis due to cholestasis is with bile acid binding exchange resins such as cholestyramine or colestipol (which is generally better tolerated than cholestyramine). Endoscopic therapy should be reserved for patients with obstructive jaundice, cholangitis, or symptomatic dominant biliary strictures. We recommend dilation of dominant strictures with graduated or balloon dilators followed by temporary stenting if the postdilation cholangiographic appearance is not improved or adequate biliary drainage cannot be assured. There is indirect evidence that the combination of ursodeoxycholic acid and endoscopic therapy to maintain biliary patency may improve transplant-free survival in patients with PSC, although this remains to be proven. Liver transplantation remains the only effective treatment of advanced PSC, and should be considered in patients with complications of cirrhosis or intractable pruritis or fatigue.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic syndrome of unknown origin mostly found in males, and characterized by diffuse inflammation and fibrosis of both intra- and extra-hepatic bile ducts. So far, PSC is considered as an autoimmune hepatobiliary disease. In most cases the progression of PSC towards liver cirrhosis and liver failure is slow but irreversible, and liver transplantation is currently the only definitive treatment. In recent years, PSC has been an area of active research worldwide with great interest in etiology, pathogenesis, diagnosis, and therapeutic options such as hydrophilic ursodeoxycholic acid and immunosuppressive agent tacrolimus. Recent updates on clinical and therapeutic aspects of PSC are discussed in the present review.

Abstract
BACKGROUND Repeat endoscopic dilatations of dominant strictures (DS) have been reported to be of benefit in patients with primary sclerosing cholangitis (PSC). We aimed to determine the prevalence of DS in patients with PSC and the spontaneous course of ALP and bilirubin, up to a year from diagnosis in patients with and without DS. METHOD Cholangiographies from 125 patients with PSC were reevaluated. DS was defined as a stenosis < or =1.5 mm in diameter of the common bile duct (CBD) and/or < or = 1.0 mm of right (RHD) or left hepatic duct (LHD). RESULTS A dominant stricture in common bile duct and/or right hepatic duct or left hepatic duct was present in 56 out of 125 (45%) patients. Mean values for alkaline phosphatase were 16 and 15.2 microkat/L and bilirubin values were 42 and 35 micromol/L before cholangiography in patients with and without DS, respectively (NS). The change in ALP and bilirubin observed from the precholangiographic value up to 2 and 12 months afterward was not significantly different in those with and without DS. CONCLUSIONS Cholestasis in patients with PSC does not seem to be related to the presence of DS. Endoscopic therapy of DS should not be routinely undertaken and randomized studies are needed to clarify its potential benefits.

Abstract
Hepatobiliary disorders occur frequently in patients with IBD, with PSC and cholangiocarcinoma being the most clinically significant for endoscopists. Endoscopic therapy for PSC is effective in improving symptoms, biochemical parameters, and radiographic abnormalities. Endoscopic therapy may also confer survival benefit, but this has yet to be confirmed in randomized, controlled trials. Treatment should be restricted to those individuals with a rapid decline in liver function testing or those with recurrent cholangitis. Cholangiocarcinoma is a serious complication of PSC and carries an extremely poor prognosis. ERCP with brush cytology has a relatively low sensitivity and the diagnosis is usually made after the disease has become metastatic. Malignant biliary obstruction can be palliated by endoscopic stenting. Photodynamic therapy is a promising experimental technique that may confer symptomatic and survival benefit in patients with nonresectable, advanced cholangiocarcinoma. IBD patients also have an elevated risk for developing acute and chronic pancreatitis as well as pancreatic insufficiency. The majority of cases of acute pancreatitis are likely due to medication side effects and local structural complications of IBD. The remainder may possibly represent true extraintestinal manifestations of IBD. Chronic pancreatitis is frequently subclinical, but may be accompanied by clinically relevant exocrine insufficiency. ERCP is the test of choice for the diagnosis of chronic pancreatitis, but the role of endoscopy in the therapeutic management of IBD-associated chronic pancreatitis remains to be defined.

Abstract
Guidelines for clinical practice are intended to indicate preferred approaches to medical problems as established by scientifically valid research. Double blind, placebo-controlled studies are preferable, but reports and expert review articles are also utilized in a thorough review of the literature conducted through the National Library of Medicine's MEDLINE. When only data that will not withstand objective scrutiny are available, a recommendation is identified as a consensus of experts. Guidelines are applicable to all physicians who address the subject, without regard to specialty training or interests, and are intended to indicate the preferable but not necessarily the only acceptable approach to a specific problem. Guidelines are intended to be flexible and must be distinguished from standards of care that are inflexible and rarely violated. Given the wide range of specifics in any health care problem, the physician must always choose the course best suited to the individual patient and the variables in existence at the moment of decision. Guidelines are developed under the auspices of the American College of Gastroenterology and its Practice Parameters Committee and approved by the Board of Trustees. Each has been intensely reviewed and revised by the Committee, other experts in the field, physicians who will use them, and specialists in the science of decision of analysis. The recommendations of each guideline are therefore considered valid at the time of their production based on the data available. New developments in medical research and practice pertinent to each guideline will be reviewed at an established time and indicated at publication to assure continued validity.

Abstract
Many hepatobiliary diseases are seen in IBD. PSC is the most common, occurring in 7.5% of patients with UC. The cause of PSC is not well understood, but PSC seems to be associated with genetic susceptibility, sharing some immunologic abnormalities with UC. A characteristic cholangiogram in a patient with abnormal liver function tests usually establishes the diagnosis. Liver biopsy is not essential but can help make the diagnosis of small duct PSC in patients with a normal cholangiogram. There are no medications that treat PSC effectively. Endoscopic dilation of dominant strictures reduces the frequency of cholangitis and may improve survival. OLT remains the only proven treatment of advanced PSC. Cholangiocarcinoma is a feared complication of PSC that is difficult to diagnose. Cholelithiasis, PBC, portal vein thrombosis, and hepatic abscess are hepatobiliary disorders that occur less frequently in IBD patients.

Abstract
There is no proven medical therapy for primary sclerosing cholangitis. The goal of management should be treatment of symptoms and complications of cholestasis, as well as attempts at treating the underlying disease process. In addition, efforts should be made to recognize and treat or prevent the known complications of primary sclerosing cholangitis, such as fat-soluble vitamin deficiency, osteopenia, dominant biliary strictures, and cholangiocarcinoma. Although some medical therapy has been shown to improve serum liver test or histology results, there has been no effect on survival or time to liver transplantation. However, preliminary data on high-dosage ursodeoxycholic acid have been encouraging. Liver transplantation remains the only effective treatment and is recommended for patients with end-stage liver disease and symptomatic portal hypertension, liver failure, and recurrent or intractable bacterial cholangitis.

Abstract
Biliary problems after a liver transplantation constitute the most frequent source of morbidity. Early recognition and nonoperative therapy have impacted short-term survival. Endoscopic therapy is the cornerstone in the initial treatment of all post-transplant biliary complications. A multidisciplinary approach involving endoscopic, percutaneous, and surgical therapies are often complementary in the management of these complex patients.

Abstract
OBJECTIVE In some patients with primary sclerosing cholangitis (PSC), a localized, high-grade (dominant) stricture may be the principal cause of symptoms and hyperbilirubinemia. The aim of this retrospective study was to compare the beneficial effects and risk of balloon dilation alone versus dilation followed by stenting in PSC patients with dominant strictures. METHODS Charts from a group of 1009 patients with PSC seen over 10 yr were reviewed to identify those patients who had undergone endoscopic or percutaneous therapeutic intervention. Procedural and clinical data were recorded. RESULTS A total of 71 PSC patients, median age of 49 yr (range 18-78 yr) were identified. Thirty-four patients were treated with endoscopic balloon dilation alone, and 37 patients were treated with balloon dilation plus stent placement. Stents were placed percutaneously (n = 19), endoscopically (n = 14), or using both interventions (n = 4). Both groups were comparable at baseline with regards to age, symptoms, and bilirubin level. The median duration of follow-up after intervention was similar in both groups. The number of intervention-related complications (30 vs 6, p = 0.001) as well as the incidence of acute cholangitis (p = 0.004) were more common in the stent group compared to the balloon dilation group. There were more complications related to percutaneous stent placement than endoscopic placement (23 vs 7. p = 0.001). There was no significant difference between the two groups with regards to improving cholestasis. CONCLUSIONS There was no additional obvious benefit from stenting after balloon dilation in the treatment of dominant strictures in PSC patients. Stenting was associated with more complications, and its role after dilation should be assessed in a randomized trial rather than being accepted as routinely indicated in this setting.

Abstract
BACKGROUND Endoscopic measures such as balloon dilation can relieve obstruction and improve symptoms in patients with primary sclerosing cholangitis (PSC). However, the influence of repeated endoscopy to maintain biliary patency on the survival of patients with PSC is unclear. METHODS This study evaluated the impact of endoscopic therapy on the survival of consecutive patients with PSC undergoing endoscopic therapy. During a 6-year period 63 patients underwent endoscopic therapy. After initial therapy, patients were followed for a median of 34 months. Endoscopic therapy primarily consisted of repeated balloon dilation of dominant biliary strictures. The observed survival of this cohort was estimated (Kaplan-Meier). The predicted survival of the cohort was estimated by using the Mayo Clinic survival model based on clinical information obtained within 3 months before first endoscopic therapy. The Mayo Risk Score was calculated by using the equation R = (0.03 Age, years) + (0.54 log(e) Bilirubin mg/dL) + (0.54 log(e) Aspartate aminotransferase U/mL) + (1.24 Bleed history) - (0.84 Albumin gm/dL). RESULTS The observed survival over 5 years was significantly higher than the predicted 5-year survival (83% vs. 65%, respectively; p = 0.027). CONCLUSION These data suggest that repeated endoscopic attempts to maintain biliary patency may improve the survival of patients with PSC and dominant strictures.

Abstract
In 1992, a 61-year-old man who complained of recurrent episodes of fever and jaundice was diagnosed as having sclerosing cholangitis. In the three years that followed, the clinical picture progressively worsened; and, in 1995, the patient was hospitalized again for biliary obstruction. A liver transplantation was excluded because of concomitant severe coronary heart disease. A percutaneous transhepatic cholangiogram showed several critical strictures of the intrahepatic biliary tree and a temporary internal-external biliary drainage was placed to relieve the obstruction. After 40 days, a two-step percutaneous biliary balloon dilation was performed followed by topical steroid treatment through the catheter. After 45 days, the catheter was removed and steroid treatment tapered orally. In the three years that followed, the patient was well. He experienced only about 1-2 episodes of ascending cholangitis per year requiring antimicrobial therapy. Laboratory analysis showed a gradual improvement in hepatic chemistry, serum bilirubin, and erythrocyte sedimentation rate (ESR). In our patient, the association of percutaneous balloon dilation and topical steroid treatment improved both the clinical and radiological picture, without significant side-effects. This approach should be considered a valuable and cost-effective option in primary sclerosing cholangitis, mainly for patients not eligible for liver transplantation.

Abstract
OBJECTIVE Symptomatic dominant strictures in primary sclerosing cholangitis are often treated with endoscopic stent therapy, but the optimal treatment duration is not well established. After a promising pilot study, we now report our 4 yr experience with short term endoscopic stent therapy for relief of dominant strictures. METHODS Between January 1994 and October 1997, 32 patients with symptomatic primary sclerosing cholangitis with a dominant stricture at endoscopic retrograde cholangiopancreatography were treated with insertion of a 7- or 10-Fr polyethylene endoprosthesis, which was extracted after a mean of 11 days (range 1-23 days). Primary end points were changes in complaints and cholestasis after 2 months, and time interval until a repeat endoscopic treatment was deemed necessary. A secondary end point was the occurrence of treatment-related complications. RESULTS Cholestatic complaints improved after 2 months in 83% of patients. Mean scores for pruritus, fatigue, and right upper quadrant pain decreased from 0.94, 1.0, and 0.87 to 0.26, 0.39, and 0.26, respectively. All improvements were significant. Of 14 patients presenting with jaundice, 12 regained normal serum bilirubin levels 2 months after short term endoscopic stenting. The mean levels of conjugated bilirubin, alkaline phosphatase, and gamma-glutamyl transpeptidase dropped significantly from 36 micromol/L, 309 U/L, and 426 U/L to 7 micromol/L, 205 U/L, and 258 U/L, respectively. The reintervention-free proportions after 1 and 3 yr were 80% and 60%. Seven transient procedure-related complications occurred in 45 therapeutic endoscopic retrograde cholangiopancreatographies. CONCLUSIONS Short term endoscopic stenting for symptomatic dominant strictures in primary sclerosing cholangitis is effective and safe, and the beneficial effect is sustained for several years.

Abstract
PSC is the most common of the clinically significant hepatobiliary diseases seen in association with IBD, with an incidence that varies from 2.5% to 7.5%. Conversely, 50% to 75% of patients with PSC have IBD. This high degree of association suggests a common pathogenetic mechanism; however, no causal relationship has been established. The etiopathogenesis of PSC remains poorly understood, despite a large number of studies looking at differing hypotheses. The diagnosis is usually established by cholangiography. Liver biopsy can sometimes be helpful in diagnosing pericholangitis. There is a significant overlap of the histology with chronic hepatitis. Serum markers have been studied for diagnosing PSC, particularly for early diagnosis of cholangiocarcinoma, but none have shown the high sensitivity and specificity needed to use them clinically. PSC usually progresses insidiously and eventually leads to cirrhosis. Despite progress in early recognition, optimal management of patients with PSC remains a challenge requiring a multidisciplinary approach among hepatologists, endoscopists, surgeons, and interventional radiologists. Colectomy for ulcerative colitis does not alter the natural history of PSC. There is a high (10% to 15%) incidence of cholangiocarcinoma in patients with PSC. This incidence along with the risk of colon cancer in patients with ulcerative colitis makes it necessary to follow these patients closely. A number of pharmacologic therapies have been evaluated, but none has proven successful in slowing the progression of PSC or prolonging survival. Endoscopic therapy has a proven utility in treating complications of recurrent cholangitis or worsening jaundice in the setting of a dominant stricture, but endoscopy has not been shown to improve survival or decrease the need for liver transplantation. Liver transplantation is life-saving for patients with advanced PSC. Pericholangitis, gallstones, and chronic hepatitis are additional disorders noted in association with IBD, but they are much less common and easier to manage than PSC.

Abstract
Cholestatic liver diseases are a diverse group of disorders that are recognized by either increases in laboratory studies or the appearance of jaundice, fatigue, pruritus, and/or complications of cirrhosis. The etiologies for most forms of these diseases are unknown. In this paper, diagnostic and therapeutic strategies are reviewed for select forms of cholestatic disorders and for the management of shared complications of cholestatic illness.

Abstract
Primary sclerosing cholangitis (PSC) is a cholestatic liver disease characterized by fibro-obliterative inflammation of the entire biliary tree. It is a slowly progressive disease with an undulating course, resulting in terminal biliary cirrhosis after a median period of about 12 years after diagnosis. The etiology of the disease is unknown and there is no effective therapy that can halt disease progression. Around 8% of PSC patients develop cholangiocarcinoma, which, by the time it is diagnosed, cannot be treated curatively. The purpose of this article is to review the current knowledge about primary sclerosing cholangitis and to speculate on future strategies to address the issues of etiology and therapy.

Abstract
OBJECTIVE The current study examines the results of extrahepatic biliary resection, nonoperative endoscopic biliary dilation with or without percutaneous stenting, and liver transplantation in the management of patients with primary sclerosing cholangitis (PSC). SUMMARY BACKGROUND DATA Primary sclerosing cholangitis is a progressive inflammatory disease leading to secondary biliary cirrhosis. The most effective management of sclerosing cholangitis before the onset of cirrhosis remains unclear. METHODS From 1980 to 1994, 146 patients with PSC were managed with either resection of the extrahepatic bile ducts and long-term transhepatic stenting (50 patients), nonoperative endoscopic biliary dilation with or without percutaneous stenting (54 patients), medical therapy (28 patients), and/or liver transplantation (21 patients). RESULTS Procedure-related morbidity and mortality rates were similar between surgically resected and nonoperatively managed patients. In noncirrhotic patients, the serum bilirubin level was significantly (p < 0.05) reduced from preoperative levels (8.3+/-1.5 mg/dL) 1 (1.7+/-0.4 mg/dL) and 3 (2.7+/-0.9 mg/ dL) years after resection, but not after endoscopic or percutaneous management. For noncirrhotic PSC patients, overall 5-year survival (85% vs. 59%) and survival until death or transplantation (82% vs. 46%) were significantly longer (p < 0.05) after resection than after nonoperative dilation with or without stenting. For cirrhotic patients, survival after liver transplantation was longer than after resection or nonoperative dilation with or without stenting. Five patients developed cholangiocarcinoma, including three (6%) of the nonoperatively managed patients but none of the resected patients. CONCLUSIONS In carefully selected noncirrhotic patients with PSC, resection and long-term stenting remains a good option. Patients with cirrhosis should undergo liver transplantation.

Abstract
Benign biliary strictures can now be effectively treated with endoscopic therapy in a variety of clinical situations. Despite recent developments in imaging techniques (endoscopic ultrasound and magnetic resonance imaging), it is often difficult to differentiate benign from malignant biliary strictures. The sensitivity of tissue diagnosis (cytology and needle biopsy) at endoscopic retrograde cholangiopancreatography (ERCP) remains poor (40-50%), and further diagnostic methods are required. Endoscopic therapy offers a definitive treatment in 70-90% of patients following post-operative biliary stricture, including anastomotic strictures following liver transplant. Endoscopic therapy successfully achieves symptomatic, biochemical, and cholangiographic response, and may improve survival in patients with primary sclerosing cholangitis. Strictures secondary to chronic pancreatitis are resistant to standard endoscopic therapy and metallic endoprotheses have been trialed with varying success. Endoscopic therapy is technically difficult and should be performed in specialized centres using a multidisciplinary approach.

Abstract
BACKGROUND In 10% to 20% of patients with primary sclerosing cholangitis, a dominant stricture of an extrahepatic bile duct is responsible for symptoms and an exacerbation of cholestasis. The complications of a dominant stricture can usually be relieved by endoscopic placement of a stent through the stricture. The conventional policy of leaving stents in situ for 2 to 3 months is associated with a high incidence (e.g., 50%) of clinical deterioration due to stent occlusion. We have attempted to overcome this problem by substantially reducing the duration of stent placement. METHODS Sixteen patients with symptomatic primary sclerosing cholangitis and dominant extrahepatic bile duct strictures were treated by stent placement for a median interval of only 9 days. RESULTS In all patients endoscopic stent therapy was technically successful with a 7% incidence of transient procedure-related complications. During median follow-up of 19 months (range 7 to 27 months) serum biochemical evidence of cholestasis decreased substantially and 13 (81%) of the 16 patients became asymptomatic. No patient had a recurrence or exacerbation of either symptoms or biochemical evidence of cholestasis that could be attributed to stent occlusion. CONCLUSIONS Short-term endoscopic stent therapy is a safe and effective treatment for symptomatic dominant extrahepatic bile duct strictures in patients with primary sclerosing cholangitis.

Abstract
BACKGROUND Possible sources of post-ERCP pancreatitis were evaluated during a prospective, randomized, controlled study comparing different contrast media. METHODS A total of 1979 patients were randomized and subdivided into groups during the study. Patients were grouped for comparison depending on the type of procedure performed during ERCP. Diagnostic patients studied with pancreatograms (Group I) were compared with other groups, specifically, those not studied with pancreatograms (Group IV). All patients had subjective and objective estimates of the difficulty in cannulation of both ducts. The incidence of postprocedural pancreatitis was compared between and within each group. RESULTS In Group I there was a progressively higher incidence of pancreatitis with increased numbers of pancreatic duct injections. Patients with the highest (19.5%) frequency of pancreatitis received 10 or more injections into the pancreatic duct. Group I cases with difficult common bile duct cannulations had a higher frequency of post-ERCP pancreatitis (9.5%), as compared with the entire group (5.6%). CONCLUSIONS There was a higher incidence of pancreatitis associated with increased manipulation around the papillary orifice, especially with multiple pancreatic duct injections. There was also a slightly higher incidence of post-ERCP pancreatitis in cases with difficult common bile duct cannulation. Endoscopists are encouraged to evaluate and develop safer cannulation techniques that minimize the number of injections into the pancreatic duct and enhance selective cannulation.

Abstract
About one-half of patients with ulcerative colitis develop abnormal liver function tests at some time during the course of the illness. This should prompt an investigation for primary sclerosing cholangitis and other common hepatobiliary diseases. Primary sclerosing cholangitis occurs in 2-10% of patients with ulcerative colitis. The diagnosis of primary sclerosing cholangitis is most often made by endoscopic retrograde cholangiography. Liver histopathology is often inconclusive but magnetic resonance cholangiography shows promise as a useful non-invasive diagnostic tool. Cholangiocarcinoma complicates 20-40% of patients with end-stage primary sclerosing cholangitis and is now one of the most common causes of death in patients with ulcerative colitis. Distinction between benign and malignant strictures can be difficult and is best done with a combination of clinical suspicion, repeated imaging for mass lesions, cholangiography, and endoscopic brushings and/or biopsies. Dominant lesions of the common bile duct or common hepatic duct produce progressive jaundice and liver damage. Early treatment may improve prognosis. Single strictures can be dilated endoscopically. If the stricture is more complicated and extends into the intrahepatic ducts or there is suspicion of cholangiocarcinoma, surgical resection may be more appropriate. Liver transplantation should be considered in end-stage disease.

Abstract
BACKGROUND In 15% to 20% of patients with primary sclerosing cholangitis, a dominant stricture of the extrahepatic bile ducts may be responsible for declining results of serum biochemical liver tests and may contribute to symptoms such as jaundice, cholangitis, pruritus, and right upper quadrant pain. METHODS Retrospectively, over the period 1985 to 1994, we evaluated 25 patients who had been treated by endoscopic stent therapy after declining results of serum biochemical liver tests and symptoms attributable to dominant extrahepatic bile duct strictures. Serum biochemical liver test results and symptoms were compared before and after treatment. RESULTS Endoscopic therapy was technically successful in 21 patients (84%). In these 21 patients results of all serum biochemical liver tests improved significantly (p < 0.001) within 6 months of stent therapy. During median follow-up of 29 (2 to 120) months after stent removal, 12 patients (57%) remained asymptomatic with stable serum biochemical liver tests and 4 (19%) had clinical and biochemical relapse of disease that responded favourably to additional endoscopic therapy. Early procedure-related complications occurred in 14% of therapeutic endoscopic biliary procedures. CONCLUSIONS Endoscopic stent therapy is a safe and effective treatment modality for an acute exacerbation of disease caused by dominant extrahepatic bile duct strictures in patients with primary sclerosing cholangitis.
