Efficacy of a paclitaxel-eluting biliary metal stent with sodium caprate in malignant biliary obstruction: a prospective randomized comparative study.

 The placement of a self-expandable metal stent (SEMS) is widely used in patients with unresectable malignant biliary obstructions, but SEMSs are susceptible to occlusion by tumor ingrowth or overgrowth. The efficacy and safety of a novel paclitaxel-eluting biliary metal stent incorporating sodium caprate (MSCPM-III) were compared prospectively with those of a covered metal stent (CMS) in patients with malignant biliary obstructions.

Novel metallic stent designed for endoscopic bilateral stent-in-stent placement in patients with hilar malignant biliary obstruction.

Endoscopic removal of a metal stent that migrated into the peritoneal cavity after EUS-guided hepaticogastrostomy.

Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is useful as an alternative biliary drainage for patients with a difficult biliary approach, but the procedure has a high complication rate . We present a case in which a stent that migrated into the peritoneal cavity was removed endoscopically under fluoroscopic guidance. A 72-year-old male with esophageal cancer presented to our department for treatment of obstructive jaundice. Metastatic peritonitis caused stricture of the distal bile duct and th...

Impact of infected stent removal on recurrent cholangitis with time-to-event analysis.

The optimal approach at treating infected biliary stents at the time of cholangitis remains unknown. This study aims to compare the efficacy of stent exchange versus stent sweeping/stent-in-stent approaches at treating cholangitis.

Acute biliary interventions.

Acute biliary conditions include cholangitis, obstruction, and biliary leakage. All these conditions may lead to severe biliary sepsis, which can be life threatening. Infected obstructed cholangitis is a medical emergency that requires active medical therapy and early biliary decompression is recommended. This article provides an overview of the clinical presentations and management of biliary sepsis. The technique, clinical applications, and outcomes of percutaneous transhepatic biliary drainage and those ...

Yield of biliary stent cytology: Is it time to think lean?

 During evaluation of pancreaticobiliary strictures, it is common practice to send biliary stents for cytologic analysis. However, in recent years, complementary tissue acquisition techniques ranging from cholangioscopy to fine-needle biopsy have improved the ability to acquire tissue and diagnose malignancy. Data are limited on the current diagnostic yield and cost effectiveness of biliary stent analysis.  We performed a retrospective study of all pancreaticobiliary stents sent for analysis in a terti...

Safety, efficacy, and removability of a fully covered multi-hole metal stent in a swine model of hilar biliary stricture: a feasibility study.

Use of fully covered self-expandable metal stents (FCSEMS) for biliary drainage of malignant hilar biliary strictures is limited because of risk of cholangitis due to side branch obstruction. The aim of this study was to evaluate the safety and efficacy of unilateral placement of a multi-hole FCSEMS (FCSEMS-MH), which had a 2.5-mm hole in the center of the membrane on each cavity, in a swine model of hilar biliary stricture. Six female mini pigs were included in this prospective study. The hilar biliary st...

The usefulness of newly modified fully covered metallic stent of 12 mm in diameter and anti-migration feature for periampullary malignant biliary strictures: comparison with conventional standard metal stent.

Fully covered self-expandable metal stent (FCSEMS) are preferred for distal malignant biliary stricture (MBS). However, stent migration is a major adverse event of FCSEMS, especially for far distal MBS. We evaluated the usefulness of newly modified FCSEMS (M-FCSEMS) having 12 mm in diameter and anti-migration feature to minimize stent migration compared with the conventional FCSEMS (C-FCSEMS).

Rescue management of recurrent duodenal and biliary obstruction due to lumen-apposing metal stent distal migration and duodenal stent ingrowth.

Use of a colonic stent to recover a biliary stent retained by malignant colonic obstruction.

Clinical Outcomes of Biliary Drainage during a Neoadjuvant Therapy for Pancreatic Cancer: Metal versus Plastic Stents.

Neoadjuvant chemotherapy/neoadjuvant chemoradiotherapy (NAC/NACRT) can be performed in patients with pancreatic cancer to improve survival. We aimed to clarify the clinical outcomes of biliary drainage with a metal stent (MS) or a plastic stent (PS) during NAC/NACRT.

Endoscopic ultrasound-guided hepaticogastrostomy using a novel covered metallic stent with a fine-diameter delivery system.

Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is a useful bile drainage method for the treatment of malignant biliary obstruction . However, its complication rate is high, and therefore various improvements in both devices and techniques have been made to improve its safety . One of the most frequent complications include bile peritonitis due to intraperitoneal bile leakage while exchanging devices during the procedure, and excessive fistula dilation when inserting the stent delivery system. Th...

Self-Expandable Metallic Stent Is More Cost Efficient Than Plastic Stent in Treating Anastomotic Biliary Stricture.

Anastomotic bile duct stricture (ABS) is one of the most common complications after liver transplantation. Current practice of endoscopic retrograde cholangiopancreatography (ERCP) with multiple plastic stent (MPS) insertion often requires multiple sessions before achieving stricture resolution. We aimed to compare the efficacy of fully covered self-expandable metallic stent (FCSEMS) with MPS method while simultaneously analyzing the relative healthcare cost between the two methods in the management of ABS.

Gene Expression Signatures Associated With Survival Times of Pediatric Patients With Biliary Atresia Identify Potential Therapeutic Agents.

Little is known about the factors that affect outcomes of patients with biliary atresia and there are no medical therapies that increase biliary drainage.

Endotherapy of postcholecystectomy biliary strictures with multiple plastic stents: long-term results in a large cohort of patients.

Endoscopic therapy of benign biliary strictures (BBSs) with multiple plastic stent (MPS) placement has shown satisfactory results. However, literature describes various BBS etiologies. Aim of this study was to evaluate long-term MPS results in patients with postcholecystectomy biliary strictures (PCBSs).

Partially Covered Versus Uncovered Self-Expandable Metal Stents: Coating Nor Diameter Affect Clinical Outcomes.

Jaundice is a common initial presentation of malignant biliary stricture. In patients with life expectancies that are greater than 3 months, self-expanding metal stents (SEMS) offer a larger diameter stent with longer patency and fewer complications compared to plastic stents. There have been conflicting results in the published literature as to efficacy and safety between the various SEMS types and diameters. We compared stent coating (PCSEMS vs USEMS) and diameter on clinical outcomes regarding managemen...

Repeat stent implementation for recanalization of the proximal right coronary artery: a case report.

A stent in a false lumen is a common cause of stent occlusion after coronary percutaneous coronary artery intervention therapy, particularly in the culprit lesion of acute myocardial infarction. Here, we present an unusual case of successful recanalization of the proximal right coronary artery with implementation of another stent to crush the previous stent in the false lumen.

'Candy Sign' in EUS guided cysto-gastrostomy of pancreatic fluid collection with metal stent.

A 40-year-old male underwent EUS guided drainage for symptomatic large WON (15 x 9 cm) due severe acute pancreatitis 6 months ago. The initial steps of EUS guided cysto-gastrostomy with BFMS (needle puncture, passage of guidewire, creation of fistula using co-axial 6Fr cystotome and dilation of track with 4mm balloon) were uneventful. However, there was significant resistance to cross the wall of WON while passing the stent assembly (NAGI stent, Taewoong Medical) over the guidewire. Subsequently, the stent ...

Short- and long-term outcomes of a novel transpapillary dilation technique using a diathermic dilator for severe benign bile duct stricture.

Endoscopic dilation for severe benign biliary stricture using mechanical dilation devices is occasionally ineffective. Hence, diathermic dilation has recently been gaining attention as a salvage procedure. We evaluated the short- and long-term outcomes of diathermic dilation for severe benign biliary stricture that could not be dilated using the conventional mechanical dilation. 13 consecutive cases with severe benign biliary stricture that underwent diathermic dilation using 6-Fr electrocautery dilator wer...

Cell-printed 3D liver-on-a-chip possessing a liver microenvironment and biliary system.

To overcome the drawbacks of in vitro liver testing during drug development, numerous liver-on-a-chip models have been developed. However, current liver-on-a-chip technologies are labor-intensive, lack extracellular matrix (ECM) essential for liver cells, and lack a biliary system essential for excreting bile acids, which contribute to intestinal digestion but are known to be toxic to hepatocytes. Therefore, fabrication methods for development of liver-on-a-chip models that overcome the above limitations ar...
