The most common biliary complication after liver transplantation is anastomotic stricture (AS) and it can occur isolated or in combination with other complications. Liver graft from a cadaveric donor or a living donor has an influence on the incidence of biliary strictures as well as on the response to endoscopic treatment. Endoscopic treatment using balloon dilation and insertion of biliary stents by endoscopic retrograde cholangiopancreatography (ERCP) is the initial approach to these complications. AIM: The aim of this article is to compare different endoscopic techniques to treat post-liver transplantation biliary strictures...

This paper presents a study of the bending flexibility of fully covered biodegradable polydioxanone biliary stents (FCBPBs) developed for human body. To investigate the relationship between the bending load and structure parameter (monofilament diameter and braid-pin number), biodegradable polydioxanone biliary stents derived from braiding method were covered with membrane prepared via electrospinning method, and nine FCBPBSs were then obtained for bending test to evaluate the bending flexibility. In addition, by the finite element method, nine numerical models based on actual biliary stent were established and the bending load was calculated through the finite element method...

OBJECTIVES: Endoscopic drainage of complex hilar tumors has generally resulted in poor outcomes. Drainage of >50% of liver volume has been proposed as optimal, but not evaluated using long multifenestrated plastic stents (MFPS) or self-expanding metal stents (SEMS). We evaluated outcomes of endoscopic drainage of malignant hilar strictures using optimal strategy and stents, and determined factors associated with stent patency, survival, and complications. METHODS: Cross-sectional study was conducted at an academic center over 5 years...

OBJECTIVE: Endoscopic retrograde cholangiopancreatography (ERCP) is used to manage biliary pathology in pediatric patients. Plastic biliary stents have been utilized in this population for obstructive lesions and bile leaks, however they are sometimes not effective due to migration, occlusion, or ineffective sealing. Fully covered self-expanding metal stents (FCSEMS) have larger diameters making them more suitable for some situations. However, their use in pediatrics has not been defined...

BACKGROUND: Endotherapy with plastic stent (PS) placement is the main modality for treating benign biliary strictures (BBSs). Fully covered self-expandable metal stents (FCSEMSs) are being increasingly used for BBS management, with high stricture resolution. However, traditional metal tents are associated with high migration, causing treatment failure. METHODS: We investigated the efficacy and safety of a new FCSEMS for postsurgical BBS treatment and compared these parameters between the FCSEMS and PS treatment through retrospective analysis...

OPINION STATEMENT: PURPOSE OF REVIEW: To review the recently published literature on biliary and pancreatic stents. RECENT FINDINGS: Covered self-expanding metal stents (SEMS) are increasingly being used in the endoscopic management of benign biliary strictures. Given the costs associated with SEMS, plastic stents are still the most commonly used stents. In this setting, SEMS are preferred over plastic stents for palliation of malignant biliary strictures due to superior patency and have a role in preoperative management of malignant biliary strictures...

BACKGROUND AND STUDY AIMS : Stent insertion at endoscopic retrograde cholangiopancreatography (ERCP) is an established therapy for managing malignant biliary obstruction. Conventional plastic stents with a tubular design are most commonly used despite limited patency. Plastic stents with a winged design may theoretically increase the duration of stent patency. The aim of this study was to compare stent patency of the winged versus conventional plastic stents in patients with malignant biliary obstruction...

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) represents an option to treat obstructive jaundice when endoscopic retrograde cholangiopancreatography (ERCP) fails. The success rate of this procedure has been shown to be very high. Up to now, plastic and self-expandable metallic stents (SEMSs) have been employed, each of them presenting some limitations. The aims of this study were to evaluate the technical and functional success rates of EUS-HGS using a dedicated biliary SEMS with a half-covered part (Giobor® stent)...

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound-guided biliary drainage (EUS-BD), first reported as an alternative to percutaneous transhepatic BD in failed endoscopic retrograde cholangiography, is sometimes performed as reintervention for transpapillary stent dysfunction such as in patients with new onset gastric outlet obstruction, but direct conversion to EUS-BD can potentially have a risk of leakage of infected bile. The aim of this study is to evaluate the safety and efficacy of conversion to EUS-BD using a temporary endoscopic nasobiliary drainage (ENBD) tube placement as a reintervention for prior BD...
