EUS-guided biliary drainage is gaining popularity as a means of achieving endoscopic drainage in patients with failed endoscopic retrograde cholangiopancreatography (ERCP) 1. EUS-guided hepaticogastrostomy (HGS) is a type of EUS-guided biliary drainage and the procedure is employed when the ERCP fails due to a malignant bile duct obstruction but the papilla is inaccessible or if the first of the duodenum is infiltrated by tumor. Recently, a novel dedicated HGS (Niti-S, Taewoong Medical, Gyeonggi-do, Korea) has become available, the stent has a novel design to that prevents the stent from migration, further improving the safety. The aim of the current study is to evaluate the feasibility and outcomes of the novel lumen apposing stent for EUS-guided HGS. The hypothesis is that the device is safe and effective.
NCT06666699
The goal of this clinical trial is to assess basic feasibility, safety, and performance of an EUS access device in patients with malignant biliary obstruction who are indicated to receive EUS-guided hepaticogastrostomy for biliary drainage. The main questions it aims to answer are: * Can the device be used to gain and maintain access to target anatomy? * Does the device have a clinically acceptable safety profile? * How does the device perform overall? All patients will undergo a hepaticogastrostomy procedure and be followed for 7 days post-procedure.
NCT06653192
The aim of this clinical trial is to evaluate the biliary drainage technical failure rate and/or the postprocedure acute pancreatitis rate between EUS-CDS vs ERCP procedures in patients with distal malignant biliary obstruction.
NCT03000855
EUS - guided choledocho-duodenostomy (ECDS) is an established option for bile duct drainage in unresectable malignant distal CBD strictures when endoscopic retrograde cholangiopancreatography (ERCP) fails. However, how primary ECDS compares with ERCP with covered self-expanding metallic stents (CSEMS) in unresectable malignant distal CBD strictures is uncertain. The aim of the current study is to compare primary ECDS versus ERCP with CSEMS in unresectable malignant distal CBD strictures. We hypothesis that ECDS is associated with a higher 1-year stent patency rate.
NCT05804201
Endoscopic ultrasonography-guided hepaticogastrostomy (EUS-HGS) is a method of obtaining biliary drainage in patients with failed or difficult endoscopic retrograde cholangiopancreatography (ERCP). The reason for failure of ERCP can be due to gastric outlet obstruction or failed cannulation. HGS involves placement of a stent between the bile duct and the stomach under the guidance of endoscopic ultrasound to create a biliary drainage route similar to surgery. The overall reported success rate is 94% with an overall complication rate of 14%. The most common complications include pneumoperitoneum (air leaking into the abdomen) and bile leak. Both complications are usually managed conservatively. EUS-gudied HGS has been commonly performed but the type of stent used for the procedure is still under evolution. A specific stent is needed to prevent complications. The most commonly used stent in HK is a hybrid stent where the liver portion is uncovered to avoid stent migration and the rest of the stent is covered to avoid bile leakage and pneumoperitonum. This stent is already available and is called the Giobor stent. However, in order to use this stent, during the EUS procedure, the bile duct needs to be first punctured by a EUS needle, then a guidewire passed, then dilate the tract with an energy deviced 6Fr cytotome, then the stent can be passed. This process is cumbersome and increase the chance of complications during exchange of the devices. A newly developed stent that is cautery-fitted has been developed. The use of this stent shortens the steps of stent application. The current study aims to evaluate the feasibility and safety of a novel stent that is cautery-fitted designed for performance of EUS-HGS (Niti-S HOT Giobor).

The effectiveness and safety of fully covered metal stent in malignant biliary obstruction caused by HCC are still unknown. These would be clarified in this prospective cohort study.
NCT05142839
EUS-guided drainages has been largely widespread during the last 10 years, even thanks to the advent of dedicated devices, such as lumen apposing metal stents (LAMSs). Above all, EUS-guided choledochoduodenostomy (EUS-CD) is to date considered a valuable option of treatment in case of distal malignant biliary obstruction in case of failure of endoscopic retrograde cholangiopancreatography (ERCP) due to the presence of a gastric or duodenal obstruction, unreachable papilla in case of altered anatomy, infiltrated papilla or failure of deep cannulation of the common bile duct. This modality of drainage demonstrated satisfying results, with high rate both of technical and clinical success with acceptable rate of adverse events. When the distal malignant biliary obstruction is associated to signs and symptoms of gastric outflow obstruction (GOO) due to the presence of a gastric or duodenal stenosis, a concomitant or subsequent palliation of the stenosis may be required. Recently, EUS-guided gastroenterostomy (EUS-GEA) has been introduced for the palliation of GOO, showing good results although technically challenging. To date, endoscopic treatment in case of GOO, enteral stenting and EUS-GEA are possible alternatives. However, available data demonstrated that EUS-GEA seems to be superior to enteral stenting in terms of rate of reinterventions during long-term follow-up, especially when life expectancy is superior to 6 months. However, data are lacking regarding which is the best strategy when GOO is associated to distal malignant biliary obstruction, especially when EUS-CD is performed. This is an hot topic, as it has been supposed that EUS-CD has higher rate of adverse events, especially food impaction, when a duodenal stenosis is present. The aim of our study, therefore, is to perform a retrospective multicenter study collecting all consecutive patients affect by distal malignant biliary obstruction drained using EUS-CD, with associated GOO treated with concomitant or subsequent duodenal stenting or EUS-GEA, in order to evaluate clinical efficacy, long term outcomes and severity of adverse events.

NCT03215108
The aim of this animal study is determining the technical feasibility of the novel flower-type covered self-expandable metal stent (F-CSEMS) and investigating whether the novel flower-type covered self-expandable metal stent (F-CSEMS) could prevent cholecystitis and pancreatitis, comparing with conventional covered self-expandable metal stent (C-CSEMS).
