<s>[INST] Last year I was operated for cholecystectomy the year after I again had that severe abdomen pain and was hospitalised for 15 days in ICU , diagnoised with CBD sludge thereafter on udiliv.  After 3 month I again had blood test and amylase was quoted 407.3 after 3 days again the same test was taken and amylase reading was 242.9 and lipase 37 .  Doctor has advised for ERCP.  My question is if the sludge is still there does not udiliv help in flushing it out, if not for what purpose has it been recommended to me.  Whether ERCP is the only cure? [/INST] Hi ! Good afternoon. I am Chat Doctor answering your query. Udiliv is a Chat Doctor.  However, this is not a 100% cure for it. Even though the pancreatic enzymes have come out to be within the normal range or of decreasing level, there possibly is a suspicion of pancreatitis by your treating physician, and also to know the complete anatomy of biliary tree along with the pancreatic duct, an ERCP is advised. This would be a near confirmatory investigation to rule out the biliary tree and the pancreatic system as the cause of your abdominal pain. ERCP could also be of therapeutic nature if the sludge/calculi in any of the biliary tree is endoscopic-ally removed. Till then, you could go for some anti-spasmodic and a proton pump inhibitor  </s>
