BACKGROUND: Endoscopic biliary stenting is a common procedure in routine gastroenterology practice. Plastic stents are the most common type of stents used and are indicated mainly for short-term biliary drainage. Prolonged indwelling plastic stents can result in disastrous complications. METHODS: We conducted a retrospective analysis of patients who presented with complications of forgotten biliary stents in a tertiary care hospital during January 2010 to October 2016...

OBJECTIVES: In patients with irretrievable or intractable bile duct stone, temporary insertion of plastic stent (PS) followed by further ERCP or surgery has been recommended as a "bridge" therapy. However, the exact mechanism of stone fragmentation has not been discovered. The aim of this study was to evaluate whether PS shape can facilitate stone fragmentation. METHODS: Using a new in vitro bile flow phantom model, we compared the friction effect among the three different PS groups (straight PS group; double pigtail-shaped PS group, and screw-shaped PS group) and the control group...

Distal malignant biliary obstruction (MBO) leads to obstructive jaundice as a result of when the bile excretion from the liver is disturbed and induces hepatic failure and sepsis, which when complicated with cholangitis, it becomes necessary to perform drainage for the MBO. For biliary drainage, we can perform a surgical bypass operation, percutaneous transhepatic biliary drainage (PTBD), endoscopic biliary drainage (EBD) via duodenal papilla, or endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD), which is a transgastrointestinal biliary drainage...

Living donor liver transplantation (LDLT) is an effective alternative to deceased liver transplantation (DDLT) for end-stage liver disease. Although advances in surgical techniques, immunosuppressive management, and post-transplant care have improved the overall outcomes of LDLT, biliary strictures remain the major unsolved problem. Endoscopic retrograde cholangiopancreatography (ERCP) is currently considered the first-line therapy for biliary strictures following LDLT with duct-to-duct reconstruction, with percutaneous and surgical interventions reserved for patients with unsuccessful management via ERCP...

AIM: To retrospectively analyze the percutaneous transhepatic techniques and their outcome in the management of biliary strictures in living donor liver transplant (LDLT) recipients. MATERIALS AND METHODS: We retrieved the hospital records of 400 LDLT recipients between 2007 and 2015 and identified 45 patients with biliary strictures. Among them, 17 patients (37.8%) (Male: female = 13:4; mean age, 36.1 ± 17.5 years) treated by various percutaneous transhepatic biliary techniques alone or in combination with endoscopic retrograde cholangiopancreatography (ERCP) were included in the study...

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.

OBJECTIVE: While the presence of biliary stent significantly decreases the accuracy of endoscopic ultrasound (EUS) for pancreatic head cancer staging, its impact on the EUS-guided sampling accuracy is still debated. Furthermore, data on EUS-fine needle biopsy (EUS-FNB) using core biopsy needles in patients with pancreatic mass and biliary stent are lacking. The aim of this study was to evaluate the influence of biliary stent on the adequacy and accuracy of EUS-FNB in patients with pancreatic head mass...

BACKGROUND: Bile leakage is a common complication after hepatic resection [1-4] (Donadon et al., 2016; Dechene et al., 2014; Zimmitti et al., 2013; Yabe et al., 2016). Endotherapy is the treatment of choice for this complication except for bile leaks originating from isolated ducts; a condition resembling the post laparoscopic cholecystectomy Strasberg type C lesions [5-9] (Lillemo et al., 2000; Gupta and Chandra, 2011; Park et al., 2005; Colovic, 2009; Mutignani et al., 2002). In such cases, surgical repair is complex, often of uncertain result and with a high morbidity and mortality [1] (Donadon et al...

BACKGROUND AND AIMS: Biliary anastomotic stricture occurs in 15% to 20% of patients after deceased orthotopic liver transplantation (OLT). It is usually treated endoscopically with multiple plastic stents (MPSs), although the use of fully covered self-expandable metal stents (cSEMSs) is emerging. This study aims to compare the efficacy and safety of cSEMSs versus MPSs in these patients. METHODS: A single-center, open-label, randomized clinical trial was performed...

Biliary strictures constitute 40% to 60% of the biliary complications after liver transplantation. They are more common after living donor related liver transplantation (LDLT) than orthotopic liver transplantation (OLT). Balloon dilation followed by multiple plastic stent insertion leads to a mean resolution rate of 84% in the treatment of ASs after OLT. Endoscopic treatment of ASs after LDLT is more difficult because of the small size of the ASs, their multiple number and peripheral location. Balloon dilation followed by multiple plastic stent insertion had a mean resolution rate of 53%...

Acute cholangitis as a result of common bile duct stones can be managed; however, cholangitis caused by occlusion with a biliary self-expandable metallic stent (SEMS) in patients with an unresectable malignant biliary obstruction has not been fully discussed. The acute cholangitis clinical guidelines (Tokyo Guidelines 2013) recommend following the same procedure as that used for cholangitis; however, the patient's condition, including performance status, tumor extension or staging, and prognosis must be considered...

Portal vein aneurysm (PVA) is a rare vascular dilatation of the portal vein. It is a rare vascular anomaly representing less than 3% of all visceral aneurysms and is not well understood. Usually, PVA are incidental findings, are asymptomatic, and clinical symptoms are proportionally related to size. Patients present with nonspecific epigastric pain or gastrointestinal bleeding with underlying portal hypertension. PVA may be associated with various complications such as biliary tract compression, portal vein thrombosis/rupture, duodenal compression, gastrointestinal bleeding, and inferior vena cava obstruction...

BACKGROUND: Fully covered-self expandable metal stents (Fc-SEMSs) have a challenging use in the treatment of anastomosis strictures (ASs) after live donor liver transplantation (LDLT) because they can occlude secondary branch biliary ducts when placed above the biliary bifurcation. In this study we evaluated the technical feasibility and safety of combining Fc-SEMSs with plastic stent(s) inserted to the secondary branch biliary ducts for the treatment of ASs after LDLT. METHODS: The study group included 22 patients (12 men, aged 51±11 years) with anastomotic biliary stricture after LDLT...

BACKGROUND AND AIMS: Treatment of anastomotic biliary strictures (ABSs) after orthotopic liver transplantation by endoscopic insertion of multiple plastic stents (MPSs) is well established. The use of covered self-expandable metal stents (cSEMSs) for this indication is less investigated. METHODS: In an open-label, multicenter, randomized trial, patients with confirmed ABSs were randomly assigned 1:1 to receive either an MPS or a cSEMS. The primary endpoint was the number of endoscopic interventions until ABS resolution...
