Filter by:Multiple risk factors have been linked with post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP); therefore, it is critical to follow strategies to reduce associated risk, morbidity, and mortality. However, there are also factors, such as pancreatic duct stenting, which have shown evidence of PEP prevention. The investigators pursue to compare plastic vs biodegradable pancreatic stents in the prevention of PEP.
Endoscopic retrograde cholangiopancreatography (ERCP) is a technically challenging procedure. It takes time to learn the basic skills and need at least 180 - 200 cases for trainees to achieve competency in ERCP. Hands-on practice in patients remains the gold standard for ERCP training. Traditional hands-on ERCP training requires the trainer to be on-site to assist the trainee with ERCP operations. We hypothesized that the trainee can be safely guided by trainer off-site with interactive audio and endoscopic and fluoroscopic view. Technology-enabled health care at a distance has profound scientific potential and accordingly has been met with growing interest. Teleguidance facilitated ERCP cannulation is a strategy to provide expert cannulation guidance to trainee in settings where such expertise is not on-site. Teleguidance not only reduces unnecessary radiation exposure of endoscopist, but also provides remote assistance for trainees to complete training or further improve skills. Given the advantages of the off-site teleguidance, it could be an attractive substitute for on-site hands-on ERCP training. The primary aim of this study was to evaluate whether off-site assistance (Off group) could achieve a comparable success rate to on-site assistance (On group) regarding the rates of successful selective biliary cannulation during ERCP training.
This study is a prospective randomized controlled trial evaluating the use of a fluorescent dye, indocyanine green (ICG), in the identification of important bile duct anatomy during emergent same-admission cholecystectomy. Participants will be randomized into either the control arm, which uses the standard of care white light during laparoscopy or the intervention arm, which will use ICG fluorescent cholangiography as an adjunct to white light to visualize the biliary anatomy. The investigators hypothesize that the use of fluorescent cholangiography will increase the rates of identification of important biliary anatomy during laparoscopic cholecystectomy. The effectiveness, feasibility, and safety will be compared between the two groups using a post-operative survey form the surgeons will complete prior to exiting the operating room.
Endoscopic retrograde cholangiopancreatography (ERCP) is the current standard technique for the treatment of pancreatobiliary disease. However, ERCP in patients with a surgically altered anatomy (SAA) remains a challenge. The short-type balloon enteroscope dedicated to pancreatobiliary intervention was recently introduced and has gained popularity as a primary modality for ERCP in patients with SAA. The currently available short-type single-balloon enteroscope (SBE) has a 3.2-mm enlarged diameter for the working channel and a 152-cm shortened working length, which can accommodate most conventional ERCP accessories and stent assemblies, and it is equipped with high-force transmission and passive bending, which facilitate passing the sharply angulated bowel segment. However, Roux-en-Y (R-Y) reconstruction anatomy is still challenging for the pancreatobiliary physician with regard to ERCP owing to the long length of the Roux and pancreatobiliary limb, and bowel angulations around the jejunojejunal anastomosis. The pooled procedural success of short SBE-assisted ERCP (SBE-ERCP) for R-Y reconstruction was reported to be 76.4% in a recent metaanalysis. The most important factor for procedural success and safety of short SBE-ERCP for R-Y patients is to resolve and prevent various bowel types looping through the collaborative manipulation of an enteroscope and overtube. In the clinical field, there is an unmet need for a formulaic loop-handing technique that can be applied to most cases of R-Y reconstruction. Therefore, in the current study, we aimed to evaluate the efficacy and safety of a mechanistic loop resolution strategy for short SBE-ERCP in patients undergoing R-Y reconstruction.
The purpose of this open-label study is to evaluate the safety and tolerability of HDT1801 (BUDCA) over 12 weeks in adult subjects with PBC who have an inadequate response to standard therapy. Inadequate response is defined as persistently elevated serum alkaline phosphatase at greater than or equal to1.5 times the upper limits of normal for the testing lab in spite of having been on adequate doses of standard therapy with UDCA (ursodeoxycholic acid) at 13-15 mg/kg for at least 6 months.
The purpose of this study is to assess the safety, outcomes and performance characteristics of multiple biliary sampling techniques including but not limited to: single operator cholangioscopy (SOC) directed biopsies, transpapillary biliary biopsies (TPBx), brushings and bile aspiration for cytology and FISH in patients undergoing ERCP.
Participants in this study will be undergoing a procedure called an endoscopic retrograde cholangiopancreatography (ERCP). This procedure is most commonly performed to help treat conditions affecting specific areas of the digestive system called the pancreas and bile ducts. Patients will consent to allow the study physician to access these areas of the digestive system by either making a cut called a needle-knife fistulotomy or a sphincterotomy.
The performance of the microbiota is observed in all clinical and pathological stages of carcinogenesis, since its development, diagnosis and treatment, including prognosis and survival. However, it was found that there is a scarcity of studies on biliary microbiota and its relationship with hepatobiliopancreatic diseases. Therefore, further investigation is necessary, since reaching the biliary microbiota may suggest ways for studies of biomarkers, diagnoses, tests and therapies in hepatobiliopancreatic diseases. For this, bile samples will be collected in cases and controls patients to characterize the microbiota and its variations according to the disease.
Biliary stricture is a common complication after end-to-end biliary anastomosis, especially after liver transplantation. This study is designed to investigate the safety and efficacy of magnetic recanalization technique, a newly clinical method, for treating biliary anastomotic stricture.
Spanish registry of resorbable stent implantation in biliary benign strictures. This registry is sponsored by the Spanish Society of Vascular and Interventional Radiology (SERVEI) and conducted by the Research Group GITMI (Group of Research in Minimally Invasive Techniques) of the University of Zaragoza (Spain). A software tool hosted on the official website of SERVEI and the journal Intervencionismo will be used for data collection a(https://estudios.watsoncme.com).
