### input:
my mom had the right lobe of her liver taken out due to cancer this last summer. she is building up a lot of fluid in her abdomen approx 7+ liters a week or less. The drs are not sure what it is. I am concerned and dont know how to direct her from long distance.

### output:

Hi there, Unfortunately the most common cause of fluid buildup in the abdomen after liver surgery is ascites, which is fluid in the abdomen that occurs when the liver isn't working very well.  It may be that the liver she has left isn't enough to work well enough to keep that fluid out of her abdomen.  The first thing that the doctors should do is make sure she is on a water pill like furosemide (lasix) and spironolactone (Gladstone). These two pills help to make sure that extra water is removed from the body and may help the fluid that is building up in her abdomen. A low salt diet will also help her. She may need continuing paracentesis (removal of the liver from the abdomen).  A procedure called a TIPS procedure (trans jugular intrahepatic portal shunt), where a shunt from the portal vein to the inferior vent cave may help to reduce the amount of ascites your mother has, but there is a work of causing or worsening encephalopathy.  It sounds like your mother needs to see doctors who have a bit more experience treating liver failure.  I'm a bit surprised if they really don't know what is causing the fluid, as (ascites) fluid in the belly after liver surgery is almost always due to the liver not working very well. I'd recommend making sure she goes to a university hospital that has experience with this.  I hope this answers your question. Please feel free to contact me if you have any further questions.
