<s>[INST] I am about to undergo a ERCP with a SOM because I have lost over 50 LBs in a year, am not absorbing nutrition or proteins , and am on Marinol, drink Ensure Plus daily and eat 5 to 6 times a day. I am 56. Although the Hida Scan showed close to normal gallbladder - it showed that the dye used was not showing in my small bowel. However - one month later when my gallbladder was removed, it was diseased, the wall thickness at greatest point was .3 cm and hard. I am afraid of the ERCP, but have no more weight to lose. I am losing Muscle now. I have no money until the first of April. [/INST] What was the reason to remove your gall bladder? Simple increased wall thickness cannot be the reason.Where gall bladder stones present?ERCP will just see the pancreas and Common bile duct from the interior. Nothing to worry. It is just like Upper GI endoscopy where endoscope is passed into these structures through the stomach. If you come back with the ERCP, i can clarify further. If you do not want ERCP, you can go for MRCP. Wish you good healthRegards </s>
