INTUSSUSCEPTION DUE TO AN INFLAMMATORY FIBROID POLYP IN THE ILEUM -AN ADULT CASE-

An intussusception due to an inflammatory fibroid polyp in the ileum is extremely rare and only 43 cases have been reported in Japan. Here we report an adult case, toghther with a review of the literature. A 70-year-old woman was admitted to the hospital because of a lower abdominal pain and abdominal fullness. There was a previous history of undergoing an open surgery recently. Abdorminal X-ray examination revealed postoperative adhesion of the ileus. After decompression by a long tube, a contrast medium study and CT scanning confirmed an obstructed ileus. Under a diagnosis of intussusception, emergency laporotomy was performed. At surgery, the intususception was found to be 8 cm in diameter and 20 cm long in the tail of the ileus. A histopathological examination of the resected specimen showed that the intussusception was due to a 2.8×2.8×2.5 cm inflammatory fibroid polyp (I.F.P.). It is important to concider IFP as a probable underlying disease in case of adult intussusception.
