Ascites a medical mystery?

My mother has a recurring ascites, has be in the hospital for 3 weeks, has had every testing you can think of, and they still don't know why she has it. The doctor's are calling her a medical mystery. She is 60 years of age, has be morbidly obese for over 35 years, a smoker (pack a day) for 35 years, a heavy drinker on weekends only for 35 years, type 2 diabetes for two years, high blood pressure, have had 2 stints placed in arteries surrounding her heart (one in 2003 and 2007), and have been taking a host of medications for years. For the ascites she's had 2 abdominal CT's, 2 MRI's, 2 upper GI tract scopes, 2 colonoscopies, and loads of blood test by two different hospitals all showing nothing of any real significance. She have tested negative for cancer, cirrhosis of the liver, kidney infection, congenital heart disease (though she has symptoms), her ovaries LOOK fine, and her digestive system LOOKS normal (no bowl movement within a week and throwing up all she takes in). She's loosing weight fast (58 pounds since the beginning of March) and getting weaker by the day because she can't keep any food down. Yesterday, the hospital did laparoscopic surgery on her tummy and though they say they didn't see anything specific, they found that her anatomy wasn't normal. They found a thick coating surrounding her intestines and adjectives her abdominal organs are stuck together by these small fibrous tissues. They've taken samples from their abnormal findings and are waiting for the results. In the meantime, they've decided to release my mother while they loaf for the results but she is still very ill. I don’t know what else to do. Can you help? Have you ever hear of anything like this or know of someone who can help?
