Endosonography Versus Magnetic Resonance Cholangiopancreatography for Choledocholithiasis for Intermediate Risk of Choledocholithiasis (as Per European Society of Gastrointestinal Endoscopy Guidelines )- Randomized Controlled Trial
Endosonography Versus Magnetic Resonance Cholangiopancreatography for Choledocholithiasis for Intermediate Risk of Choledocholithiasis (as Per European Society of Gastrointestinal Endoscopy Guidelines )- Randomized Controlled Trial
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.
Aim: Endosonography Versus Magnetic Resonance Cholangiopancreatography for Choledocholithiasis for Intermediate Risk of Choledocholithiasis (as Per European Society of Gastrointestinal Endoscopy Guidelines )- Randomized Controlled Trial
Outcomes
A.Primary Outcome :
•Sensitivity and Specificity of EUS Vs MRCP
B.Secondary Outcomes:
MATERIAL AND METHODS Study area •out-patients and in-patients in Asian Institute of Gastroenterology Study design Randamized control study Study period November 2019-March 2020
INCLUSION CRITERIA:
•Patients over 18yrs of age with suspected choledocholithiasis stratified into intermediate risk of choledocholithiasis as per European Society of Gastrointestinal Endoscopy Guidelines Guidelines
Exclusion criteria:
STUDY PROCEDURE The study will be a Randomized control study where sensitivity and specificity and secondary outcomes - cost effectiveness, adverse effects will be compared between EUS and MRCP group . All the patients presented to outpatient department or in patient wards with suspected choledocholithiasis will be screened as per European Society of Gastrointestinal Endoscopy guideline. Patients stratified into intermediate probability will be selected based on inclusion and exclusion criteria. Then patients will randomized to either EUS or MRCP based computerized software .Patients who are randomized to EUS group will undergo EUS for detection of Choledocholithiasis and then undergo Endoscopic Retrograde Cholangiopancreatography (ERCP) at same time if calculi detected and patients in whom calculi was not found, management is based on clinical judgement and 3months follow up . Patients who are randomized to MRCP group will undergo MRCP for detection of Choledocholithiasis and then undergo ERCP if calculi detected. Patients in whom calculi was not found, management will be based on clinical judgement and 3 months follow up. Based on presence of or absence of stone in Reference standard i.e in ERCP following EUS or MRCP or during 3 month follow up , sensitivities and specificities of EUS and MRCP are calculated and compared .
