BACKGROUND: Temporary placement of removable, fully covered, self-expandable metal stents (fcSEMS) for treatment of benign biliary strictures (BBS) has been reported to be effective. However, the optimal extraction time point remains unclear and stent migration has been a major concern. OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of this treatment modality using an fcSEMS with a special antimigration design and prolonged stent indwell time...

Benign biliary stricture (BBS) occurs in 7.3%-30.0% patients with chronic pancreatitis(1, 2) . In the management of BBS, fully covered self-expandable metallic stent (FCSEMS) is currently well used(3-5) . However, proximal migration of FCSEMS occurs in 10.0% recipients and is much more difficult to manage(5) . A 44-year-old man was admitted with abdominal pain and recurred obstructive jaundice a month after removal of last biliary plastic stents. This article is protected by copyright. All rights reserved.

BACKGROUND: Obstructive jaundice is frequently caused by bile duct strictures. Determination of malignant strictures is crucial for the initiation of appropriate treatment. Cytologic examination of bile drainage fluid is an easy and reproducible method of detecting malignant cells. This method, however, frequently yields indeterminate results, such as atypia or suspicious of malignancy, due to difficulties in differentiating malignancy from benign atypia. Immunocytochemical assessment of p53 expression by cells in bile drainage fluid may enhance the ability to detect malignancy...

BACKGROUND: Acute cholangitis, also known as ascending cholangitis, is a life-threatening systemic condition that results from a biliary tree infection and obstruction. Severe acute cholangitis was reported to have a mortality rate between 11 and 27% in the 1990s. This article is a literature review about acute cholangitis. Its aim is to review the latest literature about acute cholangitis and to discuss its pathogenesis, clinical presentation, diagnosis, prognosis, risk factors and treatment...

BACKGROUND AND STUDY AIMS: Complete biliary strictures normally require surgical intervention. We describe an alternative, minimally invasive endoscopic/percutaneous rendez-vous technique for the reconstruction of complete benign biliary strictures. PATIENTS AND METHODS: Complete biliary strictures were reconstructed in four patients using a rendez-vous percutaneous-endoscopic or percutaneous-percutaneous route guided by fluoroscopic and visual (transillumination) control...

Purpose To analyze the cost effectiveness of the American Society for Gastrointestinal Endoscopy (ASGE) risk stratification guidelines versus magnetic resonance (MR) cholangiopancreatography-based treatment of patients with possible choledocholithiasis. Materials and Methods A decision-analytic model was constructed to compare cost and effectiveness of three diagnostic strategies for gallstone disease with possible choledocholithiasis: noncontrast MR cholangiopancreatography, contrast material-enhanced MR imaging/MR cholangiopancreatography, and ASGE risk stratification guidelines for diagnostic evaluation recommending endoscopy (high risk), MR cholangiopancreatography (intermediate risk), or no test (low risk)...

BACKGROUND AND AIMS: Probe-based confocal laser endomicroscopy (pCLE) using the Miami Criteria has improved classification of indeterminate biliary strictures. However, previous biliary stenting may result in their misclassification as malignant strictures. Inflammatory criteria were added to form the Paris Classification to prevent this misclassification and reduce false positives. The aim of this study was to assess if the Paris Classification was more accurate than the Miami Classification in classifying indeterminate biliary strictures after biliary stenting...

Benign biliary strictures (BBSs) are commonly caused by surgical injury, chronic pancreatitis, and inflammatory cholangiopathies. Although advanced imaging tests and tissue acquisition methods have been developed for evaluation of indeterminate biliary strictures, differentiation of BBSs from biliary malignancies remains a challenge to clinicians. The majority of BBSs have good response to nonsurgical treatment and surgical intervention mainly serves as a rescue when nonsurgical approaches fail. Endoscopic management is a safe, effective, and less-invasive treatment for BBSs compared with other approaches...

Biliary strictures are caused by a heterogeneous group of benign and malignant conditions, each requiring a specific treatment approach. Management of biliary strictures often involves endoscopy either for definite treatment, as a bridge to surgery or for palliative purposes. Endoscopic treatment of various types of biliary strictures is not standardized and there are multiple areas of controversy regarding the best treatment options. These controversies are mainly due to lack of well-designed comparative studies to support a specific therapy...

There is a wide variation in the clinical presentation of chronic pancreatitis (CP) in the different parts of India. Data regarding the clinical profile of CP from eastern India are scarce. We describe the clinical and demographic profiles of patients with CP in eastern India. Consecutive patients were evaluated for the clinical presentation, etiology and complication of CP. One hundred and thirty-nine patients with CP (mean age 39.57±14.88 years; M/F 3.48:1) were included. Idiopathic CP (50.35%) was the most common etiology followed by alcohol (33...

BACKGROUNDS/AIMS: Despite hepatolithiasis being a risk factor for biliary neoplasm including cholangiocarcinoma, the incidence of underlying biliary neoplasm is unknown in patients with preoperative benign hepatolithiasis. The aim of this study was to evaluate the incidence of underlying biliary neoplasm in patients who underwent major hepatectomy for preoperative benign hepatolithiasis. METHODS: Between March 2005 and December 2015, 73 patients who underwent major hepatectomy for preoperative benign hepatolithiasis were enrolled in this study...

The diagnosis of biliary strictures can be challenging. Endoscopy has an established role in the diagnosis and therapy of biliary strictures. However, the diagnostic yield from conventional endoscopic retrograde cholangiopancreatography tissue sampling is modest. Improvements in existing technologies as well as the implementation of novel technologies and techniques have the potential to improve the diagnostic performance of endoscopy and expand its therapeutic role. Recent studies have enabled greater clarity about the role of preoperative biliary drainage and the choice of stents in this setting as well as the utility of metal stents in benign and malignant disease...

AIM: To investigate presence and extent of eosinophilic cholangitis (EC) as well as IgG4-related disease in patients with indeterminate biliary stricture (IBS). METHODS: All patients with diagnosis of sclerosing cholangitis (SC) and histopathological samples such as biopsies or surgical specimens at University Hospital Frankfurt from 2005-2015 were included. Histopathological diagnoses as well as further clinical course were reviewed. Tissue samples of patients without definite diagnosis after complete diagnostic work-up were reviewed regarding presence of eosinophilic infiltration and IgG4 positive plasma cells...

Hepatobiliary cystadenomas (HBC) is a rare neoplasm which comprising less than one percent of liver cystic neoplasms. Although it's known as a benign tumor, but they have a potential for neoplastic transformation. Making a proper diagnosis and ruling out of other differential diagnosis is important because of different treatment. In the present study, we described a case of HBC manifested as idiopathic dominant biliary stricture in common hepatic duct (CHD), on the basis of spiral CT scan and MRI, and elevated CA19-9...

BACKGROUND: Postoperative cholangitis is one of the major late complications after pancreaticoduodenectomy (PD), and recurrent cholangitis has a negative impact on patients' quality of life. However, detailed reports are scarce. The aim of this study was to investigate the clinical features of postoperative cholangitis after PD. METHODS: Between January 2007 and December 2013, 155 consecutive patients underwent PD. Of these, 113 patients were included in this study...
