Thank you for your response, I will talk to my doctor again. Will let, you know what he says. Thanks again for your help.
Jennie, have you changed your diet to a low-fat one? If not, consider doing so. In addition, try to identify any foods outside of the 'usual suspects' that may be causing your problems and take them out of your diet.
The upper gastric pain could be the result of acid reflux, but it could also be due to spasms of the common bile duct. In addition to the endoscopy, please make sure your doc considers doing and MRCP which will show whether or not there is any sludge or stones that may have escaped during surgery. That issue needs to be considered.
