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). 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 efficacy and safety of cSEMSs versus MPSs in these patients. METHODS: single center, open-label, randomized clinical trial. Patients were randomized to single cSEMSs for 6 months or to MPS placement, exchanged every 3 months during 1 year...

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...

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...

BACKGROUND/AIM: In research and development of biliary plastic stents (PS), continuous efforts have been made to overcome short patency time and high rate of migration. The aim of this study was to evaluate the patency and migration rate of different PS shapes for a given period of time. METHODS: Using an in vitro bile phantom model, we compared the patency among different shapes of PS (three straight PS, four double-pigtail PS, and a new screw-shaped PS). We performed an analysis of the degree of luminal narrowing by light microscopic examination...

BACKGROUND: Hepaticojejunostomy is routinely performed in patients when inoperable disease is found at planned pancreatoduodenectomy; however, in the presence of self-expanding metal stent (SEMS) hepaticojejunostomy may not be required. The aim of this study was to assess biliary complications and outcomes in patients with unresectable disease at time of planned pancreaticoduodenectomy stratified by the management of the biliary tract. MATERIAL AND METHODS: Retrospective analysis of patients undergoing surgery in January 2010-December 2015...

Here, we report our experience with a case of severe biliary bleeding due to a hepatic arterial pseudoaneurysm that had developed 1 year after endoscopic biliary plastic stent insertion. The patient, a 78-year-old woman, presented with hematemesis and obstructive jaundice. Ruptured hepatic arterial pseudoaneurysm was diagnosed, which was suspected to have been caused by long-term placement of an endoscopic retrograde biliary drainage (ERBD) stent. This episode of biliary bleeding was successfully treated by transarterial embolization (TAE)...

AIMS: Pre-operative biliary drainage (PBD) can relieve adverse effects of cholestasis, however carries risk of procedural complications. Metal stents have wider lumens and longer patency, although plastic stents (PS) may still be useful for short term drainage. We reviewed outcomes from PBD at our centre. METHODS: Patients with symptomatic cholestasis and those likely to wait longer than 2 weeks for surgery treated with PBD between January 2011 and May 2015 were included...
