Active clinical trials for "Choledocholithiasis"

Machine learning predictive model can help in stratifying heterogenous intermediate likelihood group to reduce need for EUS or MRCP in selected subgroup of patients.

Endoscopic retrograde cholangiopancreatography (ERCP) has been widely used in diagnosis and treatment of pancreaticobiliary diseases. Traditionally, ERCP has been performed in the prone position. The prone position for ERCP can facilitate selective bile duct cannulation, offer a better fluoroscopic image of pancreaticobiliary anatomy, and prevent aspiration of gastric contents. However, in cases of difficult in the prone position, ERCP has been performed in the left lateral or supine position. Compared with the prone position, left lateral position is more comfortable for patients, especially with limitation for cervical movement including cervical cord injury, cervical spine operation, parkinson's disease, contracture due to cerebral infarction, and allow more easy passage of the scope through the pharynx, and useful to secure airway. However, in the left lateral position, it is difficult to obtain fluoroscopic image of right hepatic duct and intrahepatic bile duct. In cases of severe abdominal pain, severe abdominal distension, large amount of ascites, recent abdominal surgery or cervical spine surgery, intra-abdominal catheter insertion, severe obesity, it is difficult to position in prone or left lateral, therefore, ERCP may be performed in the supine position. In supine position for ERCP, there has been documented increased risk of cardiopulmonary adverse event and decreased success rate of selective bile duct cannulation. There have been reported the efficacy and safety between the prone position and supine position for ERCP in several studies. We aimed to evaluate the efficacy and safety between the prone position and left lateral position for ERCP in this prospective, randomized study.

The aim of this study is to demonstrate that patients with high risk of choledocholithiasis who undergo ERCP only for patients with choledocholith in the EUS examination[EUS-ERCP group] have less negative outcomes (including false-negative results and procedure-related complications) than patients who undergo ERCP in all patients with high risk of choledocholithiasis[ERCP group]. The primary outcome is the incidence of negative outcomes (including false-negative results and procedure-related complications) in both groups. The secondary outcomes included days of hospitalization and the rate of diagnostic ERC.

The present study aimed to compare early and delayed laparoscopic cholecystectomy after ERCP for CBDs and gallstones.

This study aims to evaluate post-operative pain in single-incision laparoscopic cholecystectomy (SILC) versus the conventional four port technique (LC). The investigators hypothesize that SILC is non-inferior in post-operative pain.

The objective of this observational study is to explore the structure of biliary flora in normal people, explore the dynamic impact of ERCP and EST on biliary microecology, study the marker flora, metabolites and functional genes related to biliary diseases, explore the occurrence and development mechanism, regulatory pathways and key targets of biliary diseases, and provide new strategies for the prevention and treatment of biliary diseases from the perspective of biliary microecology.

This study is designed to assess whether a new technique called facilitated endoscopic retrograde cholangiopancreatography (ERCP) is or is not superior to conventional ERCP for removing stones found in the bile duct at the time of laparoscopic cholecystectomy. ERCP is an endoscopic procedure used to facilitate the radiological examination and subsequent manipulation of the common bile duct (eg. opening it up, which is called sphincterotomy). Both facilitated and conventional ERCP are performed as a separate procedure after the initial gallbladder surgery. This is a comparative study of these two techniques in a randomised clinical trial. The aim of this randomised clinical trial is to enable surgeons to decide whether placement of a plastic stent at the time of laparoscopic cholecystectomy will improve the success rate and safety of subsequent ERCP and sphincterotomy.

A Recent Meta analysis, showed pooled sensitivity and specificity were 97% and 90 for EUS and 87% and 92 for MRCP . This meta analysis includes only 5 studies, smaller sample size in each study, significant heterogeneity in reference standards ranged from ERCP and Intra operative cholangiography (IOC) to clinical follow up for negative patients . Furthur validation of EUS Vs MRCP is needed in detecting common bile duct caliculi in intermediate risk of choledocholithiasis To date Randamized control trail comparing EUS Vs MRCP in detecting Choledocholithiasis lacking , hence the investigators aimed a Randamized control trail determining and comparing the sensitivity and specificity of EUS and MRCP in diagnosing Choledocholithiasis.

In this prospective study, the investigators assessed the utility of intermittent saline irrigation in reducing the recurrent rate of choledocholithiasis after the endoscopic extraction for common bile duct stones, and it does not increase the rate of procedure-related complications.

This pilot study aims to determine the utility of direct Magnetic Resonance Cholangiopancreatography (MRCP) in the assessment of suspected acute gallstone disease presentations. This will take the form of a randomized controlled trial, the design of which is based on recent internal audit data which indicated that a high proportion of patients ultimately require MRCP prior to diagnosis, treatment and discharge, and suggested that early scan may improve overall costs and outcomes. Patients with symptoms and signs suggestive of suspected gallstone disease and deranged liver function tests/amylase (i.e. suggestive of a potentially obstructive gallstone disease), will be enrolled across the full range of 'front-door' locations for surgical presentations within the hospital (Emergency Department, Surgical Emergency Unit, Ambulatory Assessment Unit), and randomized to one of two diagnostic pathways which are both existing variations in current clinical care: MRCP is used as the first mode of imaging; following a standard care model (ultrasound then MRCP if deemed appropriate). An assessment will then be undertaken of the cost-effectiveness of early MRCP versus standard care, using the primary outcome measure of cost to diagnostic scan report calculated using hospital episode statistics (HES), with secondary outcome measures to assess the overall utility which include length of stay, time to diagnosis, overall cost of admission using HES, in-hospital complications, Patient Reported Outcome Measures (PROMs), readmission and re-attendance rates (ED/GP), and service/radiology costs.
