ello,
Welcome to the ehealthforum and I am glad to help you out.
I can understand your concern. These symptoms do not look like hidden celiac or Hashimotos disease. It looks like the swelling near the bile duct is due to any stone being left behind in the bile duct or due to post cholecystectomy syndrome. For the swelling of the bile duct, you should consult a gastroenterologist as you might need further investigations like an ERCP to look for the cause of the swelling of the bile duct. In this procedure, a tube is passed into the bile duct to look for the cause of the swelling as stone could be blocking the opening of the bile duct into the intestine.
In post cholecystectomy syndrome, there’s persistent pain and associated nausea/vomiting. This occurs primarily due to either the adhesions which are formed in the area of the surgery or due to the dysfunction of the sphincter of oddi. Since the reservoir of the bile i.e. gall bladder has been surgically removed, it results in a continuous flow of the bile into the intestine resulting in gastritis & esophagitis. The sphincter of oddi dysfunction is treated by using high doses of calcium channel blockers or nitrates. ERCP is a procedure which is done to look for the cause of the post cholecystectomy syndrome and is also used for the treatment.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
