Unexplained dilated common bile duct

First sorry for my english : I’m French.

I’ve had pain under right ribs since March. (!)

Then pain when eating. Bloating, even worse in the evening, fragmented stool, yellowish brown colored. No appetite. No weight loss (I eat because I’m afraid of weighting loss).

And I have also now pain at the right of my belly button.

I had : ultrasound and bloodwork in April. Normal.

CT scan in June : normal except a slight dilatation in distal common bile duct (7 mm).

MRCP in June : Slight dilatation in common bile duct and a rather abrupt termination of the distal common bile duct (which is a sign of malignancy as for Doc Google)

EUS in June : all normal. CBD 2,1 mm. Pancreas perfect.

My GI said everything is OK. Don’t worry. He took the MRCP report to be interpreted by another radiologist who said, in his opinion, there was no abrupt termination but it was rather the anatomy of my sphincter of Oddi. And he is not worried by the bile duct dilatation.

He said I was too much anxious,

My mum died from either pancreatic or biliary cancer. I know she had whipple, and died 9 years later.

So of course I´m anxious !!

Bloodwork still OK, LFT included.

I had another EUS yesterday with another GI. He understood my anxiety and said he would be particularly cautious at inspecting the distal common bile duct.

Report says : pancreas, gallbladder, liver OK. Common bile duct visible all along with no apparent obstacle, either stone or tumor.

Intrapancreatic common bile duct is 2 mm.

Suprapancreatic common bile duct is dilated at 8 mm.

Common bile duct at his maximum (I think at the highest ?) is 4 mm.

These observations stay within normal ranges.

He then said to me : don’t worry. I looked everywhere and saw nothing bad or worrying.

He said : we will make EUS yearly because of your mother history.

Well, I don’t know if I’ll still be there next year ... My symptoms are making me mad.

And how can my common bile duct be dilated without an explanation ?

It’s like you imagine a pipe being 4 then 8 then 2 mm ??

I’ m at a lost...

I know EUS is a very reliable exam and I try to convince me that if there was something sinister it should have been seen.

I know the GI spent a long time yesterday for the EUS.

Does anybody had unexplained dilated common bile duct ? With my symptoms ?

Thanks for your answers.
