Filter by:This registry aims to analyze long-term outcomes of therapeutic EUS (T-EUS) procedures, as well as to describe clinical and technical variables potentially predicting clinical success or adverse events, for a better selection of ideal candidates.
Distal malignant biliary obstruction results from different types of tumors including pancreatic cancer, biliary tract cancer (BTC), gallbladder cancer, and metastasis, which can lead to obstructive jaundice. Endoscopic retrograde cholangiopancreatography (ERCP) represents the gold standard for jaundice palliation in this setting of patients. However, surgically altered anatomy (i.e., Whipple intervention, Roux-en-Y gastric bypass, Billroth II surgery), periampullary diverticula, gastric outlet obstruction, and malignant obstruction of the lumen determine the failure of the procedure in about 5-10% of cases, requiring alternative methods of decompression. Percutaneous transhepatic biliary drainage (PTBD) and surgical bypass are well established alternatives in these patients, but associated with increased morbidity, longer length of hospital stay and higher costs, and patient discomfort. In 2001 Giovannini et al. described the first EUS guided biliary drainage (EUS-BD) through a transduodenal access with a needle knife. Subsequently, EUS-BD has considerably evolved thanks to the development of dedicated devices such as lumen apposing metal stents (LAMS), specifically designed for endoscopic ultrasound procedures. LAMS are made up of braided nitinol, that is fully covered with silicone to prevent tissue ingrowth, with wide flanges on both ends to provide anchorage. Recently, LAMS have been incorporated into a delivery system with an electrocautery mounted on the tip (Hot Axios; Boston Scientific Corp.), which allows the device to be used directly to penetrate the target structure without the need to utilize a 19G needle, a guidewire, and a cystotome for prior dilation. This has been described for drainage of peri-pancreatic fluid collections, common bile duct (CBD), gallbladder, and for creation of gastro-jejuno anastomosis. The biliary drainage procedure performed with the Hot Axios sistem is a one step procedure that requires less or no need for accessory exchange and becomes faster, thus potentially decreasing the risk of complications. The procedure has been described as safe and effective with a technical success of 98.2 %, clinical success of 96.4 %, and low rate of complications 7 % (duodenal perforations, bleeding and transient cholangitis). A systematic review and meta-analyses showed clinical and technical success rates of 87% and 95% respectively. Currently, the EUS-BD is indicated as a rescue therapy for jaundice palliation after ERCP failure.
The study aim to evaluate the efficacy of intraductal radiofrequency ablation for unresetable hilar cholangiocarcinoma in addition to biliary stenting. The patient would be randomized into 1:1 ratio of conventional group who received biliary stenting alone, and RFA group who receive intraductal RFA before biliary stenting. Immediate complications as well as long term stent patency and patient survival would be studied.
The aim of the study is to evaluate technical, clinical and safety outcomes of lumen-apposing metal stent (LAMS) with and without a coaxial double-pigtail plastic stent (DPS) in EUS-guided choledochoduodenostomies (CDS) for the management of biliary obstruction.
Malignant obstructions of the bile duct are not rare. The most common and accepted method for biliary drainage is endoscopic stent placement. There are three types of metal stents: fully covered (FC), partially covered (PC) and uncovered (U). PC-SEMS have been recently introduced and compared to FC-SEMS they seem to have a lower risk of migration, although data in the literature are discordant. Therefore the investigators will randomize the participants with biliary obstruction in 2 groups according to the type of stent used: PC-SEMS or U-SEMS. After metallic biliary stent insertion, enrolled patients will be followed for 12 months.
This was a retrospective case series experience of paediatric patients who had an Isolated vascularized gastric tube biliary enteric drainage procedure for biliary obstruction over the past five years. We reviewed our experience and outcomes.
The impact of preoperative biliary drainage (PBD) on morbidity and mortality associated with Pancreaticoduodenectomy (PD) in patients with peri-ampulary tumors is still controversial. The objective of this study is to evaluate the impact of PBD on surgical and oncologic outcomes after PD in jaundiced patients with operable peri-ampulary tumors.
DIGEST I Pilot study is a feasibility study for evaluating the safety and efficacy of DCBs.
The purpose of this study is to compare the clinical effectiveness and long-term outcomes between patients with pancreatic carcinoma and biliary obstruction who are treated by stent insertion with or without high-intensity focused ultrasound ablation.
We describe a case of a 57-year-old patient with altered RYGB anatomy, who underwent a laparoscopic cholecystectomy with a intra-operative cholangiogram showing a stone on the common bile duct. A laparoscopic assisted trans-gastric ERCP was successfully performed. The presentation of the case is presented as well a review of the literature.
