Ascites

I think that my dad has ascites - abdominal swelling and swelling in arms/legs (gone now) but still has minor abdominal swelling (went down a lost this past week due to a fluid pill). He is on treatment. I wanted to know if anyone out there had success of getting rid of this. My goal is to get him to the point where he can have sir spheres and a similar procedure done to his lung. Last CT in August showed potential spot in abdomen near esophagus so radiologist said procedure was not possible - need to get rid of that. Since then, he has had pnemonia and now this swelling which has caused him to lose 20 pounds in 4 months. Any suggestions would be helpful.

Thanks,

Jennifer
