Transjugular intrahepatic portosystemic shunt as a treatment for protein-losing enteropathy caused by portal hypertension.

A case of a 41-year-old man with diarrhea, hypoalbuminemia, and cryptogenic cirrhosis with features of portal hypertension is described. Protein-losing enteropathy was confirmed by analysis of whole-gut lavage fluid, and intestinal inflammation and infection were excluded. Distal duodenal biopsy specimens showed evidence of edematous villi with prominent submucosal vascular and lymphatic vessels. A transjugular intrahepatic portosystemic stent-shunt was inserted, resulting in resolution of both his diarrhea and elevated whole gut lavage fluid protein concentrations. His symptoms recurred and then again improved after shunt thrombosis and parallel shunt placement, respectively. Histological improvement of the villous edema was also noted. This is the first recorded case of protein-losing enteropathy caused by portal hypertension confirmed by successful treatment with transjugular intrahepatic portosystemic stent-shunt.
