Dear friend, welcome and thanks for entrusting your query here at HCM!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
Free fluid in the abdomen if more than minimal can be significant.
Was it free fluid or fluid within the bowel or gall bladder? Your description does not clarify it.
Fluid may collect from various causes- infective, perforation/ rupture of an organ like gall bladder/ bowel, or generalized disorder like low proteins
You need an actual in person examination by a physician to differentiate it.
So, yes the radiologist
rightly asked you to see your doctor again.
Pl. keep me posted on what happens.
I hope you are fully satisfied with the guidance I gave.
I would be glad to answer any further queries. May I request you to rate your experience here before you close.
Thank you and Good luck!
