You mentioned that the MRCP had shown retained stone or stones in the
common bile duct , yet at ERCP they did not find any . Either the stones
moved back up or dropped down after they made a cut into the duct.
Usually bleeding occurs during or right after the procedure although
delayed bleeding can happen with activity. It is possible the spasms could
indicate movement of the retained stone and they would be dropping into
the intestine and eventually passed in the stool. Diarrhea
may be related
to the slightly excess bile that is released into the intestine after the
procedure , which can be normal and should not last long. If you have
increasing abdominal pain
, feeling faint etc , you should get in
touch with the doctor as soon as possible to find out if there is any delayed
In any event you need to be closely observed .
I wish you the very best.
