Hello Susan and welcome to MedHelp. I am sorry you and your husband have been thru so much lately. The amount of frustration you must be feeling is simple to fathom.
Here is some information I found: http://www.nlm.nih.gov/medlineplus/ency/article/001157.htm
Causes
Mesenteric venous thrombosis is a clot that blocks blood flow a mesenteric vein, one of two veins through which blood leaves the intestine. The condition interrupts the blood supply to the intestine and can result in damage to the intestines.
Mesenteric venous thrombosis has a variety of causes. Many of the diseases that lead to this condition cause swelling (inflammation) of the tissues surrounding the veins, including:
• Appendicitis
• Cancer
• Diverticulitis
• Liver disease with cirrhosis
• Pancreatitis
Patients who have disorders that make the blood more likely to stick together (clot) have a higher risk for mesenteric venous thrombosis. Birth control pills and estrogen medicines increase your risk of this condition.
Symptoms
• Abdominal pain, which may get worse after eating and over time
• Bloating
• Diarrhea
• Fever
• Gastrointestinal bleeding
• Vomiting

I think at this point the focus of his treatment needs to immediately go to mysenteric venous thrombosis despite the conclusion that it is under control. More pain medication is not a very practical treatment for persons with cirrhosis since most pain medication will cause liver disease to advance.
Also try MedHelp’s Deep Vein Thrombosis, they might be able to help too.
