hepaticogastrostomy

BACKGROUND: Hepaticogastrostomy drainage through endoscopic ultrasound (EUS-HGS) has emerged in the 2010s as a new technique for biliary decompression in cases of endoscopic retrograde cholangiopancreatography (ERCP) failure for malignant biliary obstruction (MBO). Substantial technical and procedural progress in performing EUS-HGS has been achieved, allowing high technical and clinical success and an acceptable risk of adverse events in studies mainly focusing on short-term outcomes...

BACKGROUND/AIMS: Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (EUS-HGS) performed at the intrahepatic bile duct segment 3 (B3) is widely used for biliary drainage. Although performing post-puncture procedures is easier in the intrahepatic bile duct segment 2 (B2) when using a conventional oblique-viewing (OV) EUS scope, this method may cause transesophageal puncture and severe adverse events. We evaluated the safety and efficacy of B2 puncture using a novel OV-EUS scope. METHODS: In this single-center retrospective study, we prospectively enrolled and collected data from 45 patients who consecutively underwent EUS-HGS procedures with a novel OV-EUS scope between September 2021 and December 2022 at our cancer center...

Background : Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is an alternative for failed endoscopic retrograde cholangiopancreatography (ERCP), with current success rates of 65-84% considered suboptimal. A novel ERCP catheter (SHOREN, Kaneka Corporation, Osaka, Japan) with a tapered 3.3-French tip may facilitate smoother insertion, potentially improving outcomes. Methods : This retrospective analysis encompassed EUS-HGS procedures conducted from January 2021 to August 2023 at four institutions. The aim of this study was to compare the performance of conventional and novel ERCP contrast catheters regarding the success rate of single-attempt catheter insertion, failure rates, technical success rates, and incidence of adverse events...

BACKGROUND: Endoscopic ultrasound-guided biliary drainage (EUS-BD), classified as choledochoduodenostomy (CDS) and hepaticogastrostomy (HGS), is a feasible and effective alternative for distal malignant biliary obstruction (MBO) in failed endoscopic retrograde cholangiopancreatography. However, the preferred technique for better outcomes has not yet been evaluated. OBJECTIVES: We compared the long-term outcomes between the techniques. DESIGN: Retrospective comparative study...

We report a case in which a large amount of intraperitoneal free gas developed during endoscopic ultrasound-guided biliary drainage with the rendezvous technique. A 62-year-old woman presented with obstructive jaundice caused by a pancreatic head tumor. Endoscopic retrograde cholangiopancreatography was attempted but failed due to difficulty cannulating the bile duct. Consequently, endoscopic ultrasound-guided hepaticogastrostomy was performed using a fully covered metal stent. Subsequently, the rendezvous technique was employed to access the biliary system and perform an endoscopic sphincterotomy...

Background and study aims In cases of inaccessible papilla, EUS-guided biliary drainage (EUS-BD) has been described as an alternative to calibrate benign biliary stenosis. However, few studies are available. Patients and methods This tw-center, retrospective study was designed to evaluate technical success and clinical success at 1 year. All patients who underswent EUS-BD without the rendezvous technique used for calibration of benign biliary stenosis were included from 2016 to 2022. Patients underwent EUS-hepaticogastrostomy (EUS-HGS) during the first session...

BACKGROUND AND STUDY AIM: EUS-guided hepaticogastrostomy (EUS-HGS) is a valid option for EUS-guided biliary drainage that has been increasingly used in the last decade. The aims of the study were to provide a systematic review with meta-analysis and meta-regression of features and outcomes of this procedure. METHODS: MEDLINE, Scopus, Web-of-Science, and Cochrane databases were searched for literature pertinent to EUS-HGS. Meta-analysis of proportions and meta-regression of potential modifiers of the main outcome measures were applied...

BACKGROUND AND AIMS: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is a rescue procedure when endoscopic retrograde cholangiopancreatography fails. Peritonitis and recurrent biliary obstruction (RBO) are adverse events (AEs) associated with EUS-HGS. Antegrade stenting across a malignant distal biliary obstruction (MDBO) followed by EUS-HGS (EUS-HGAS) creates two biliary drainage routes, potentially reducing peritonitis and prolonging time to RBO (TRBO). We compared the outcomes of the two techniques...

Background and study aims Balloon dilation and plastic stent deployment have been performed as hepaticojejunostomy stricture (HJS) treatment techniques under endoscopic ultrasound guidance (EUS). Although these techniques have shown favorable clinical results, the treatment period can be long because stent deployment is required. In addition, HJS may recur even after treatment because the scar tissue itself remains. To overcome these challenges, we developed an EUS-guided antegrade drill dilation technique for treating HJS...

Background and study aims This retrospective study aimed to investigate risk factors for early adverse events (AEs) associated with endoscopic ultrasonography-guided hepaticogastrostomy (EUS-HGS) using self-expandable metal stents (SEMS). Patients and methods The clinical success rate, technical success rate, and early AEs were assessed at two hospitals from 2010 to 2022. The analysis focused on risk factors associated with cholangitis, peritonitis, and SEMS migration. Results Technical success was achieved in all cases (94/94), and clinical success was 96...

Tract dilation is an essential step in completing endoscopic ultrasonography-guided hepaticogastrostomy (EUS-HGS). EUS-HGS using a 22-gauge needle is currently attracting attention; however, the complexity of subsequent dilation and guidewire exchange is problematic. A-60-year-old man with duodenal cancer was referred to our center for the drainage of obstructive jaundice. As endoscopic retrograde cholangiopancreatography was not feasible because of duodenal obstruction, EUS-HGS was performed.

Background and study aims Percutaneous transhepatic biliary drainage (PTBD) is the traditional second-line option after unsuccessful endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HG) is a viable alternative to PTBD. Our study aimed to compare outcomes of EUS-HG and PTBD for benign and malignant biliary diseases following failed ERCP. Patients and methods This single-center study retrospectively analyzed patients undergoing EUS-HG and PTBD for benign and malignant biliary disorders...

BACKGROUND AND AIMS: Definitive peroral endoscopic treatment of pancreaticobiliary pathology in patients with surgically altered anatomy has recently been made more feasible by the use of lumen-apposing metal stents (LAMS) to create bowel-to-bowel anastomoses. We aim to demonstrate 4 cases of non–gastric bypass Roux-en-Y anatomy for which an enteroenterostomy was created under EUS guidance to facilitate complex peroral ERCP. METHODS: Akin to EUS-directed transgastric ERCP, the approach to EUS-directed transenteric ERCP involves identification and expansion of the target bowel before transmural puncture and stent placement...

Progression of pancreatic adenocarcinoma can result in disease complications such as biliary obstruction and gastric outlet obstruction. The recent advances in endoscopic ultrasound (EUS) have transformed EUS from a purely diagnostic technology to a therapeutic modality, particularly with the development of lumen-apposing metal stents. In terms of biliary drainage, EUS-guided choledochoduodenostomy and EUS-guided hepaticogastrostomy offer safe and effective techniques when conventional transpapillary stent placement via ERCP fails or is not possible...
