[Idiopathic sclerosing peritonitis (ISP). A report of a new case and a review of the literature].

Idiopathic sclerosing peritonitis (I.S.P.) is a rare disease, in which the small bowel is encased in a fibrous capsule, with symptoms and signs of intestinal obstruction. A new case of I.S.P. in a 42-year-old man who underwent laparotomy and was reoperated for intestinal obstruction is presented. A jejunal fistula with a favorable outcome occurred in this case. The literature about this entity is reviewed, and 16 cases are collected. This condition is being reported more and more commonly and requires further research to elucidate its unknown mechanism.
