Abstract
A 56-year-old woman who visited a neighboring hospital because of intermittent bouts of right lower quadrant abdominal pain was found to have findings suggestive of intussusception by an abdominal ultrasonography, and she was referred to our hospital. There was rebound tenderness in the right lower quadrant of abdomen. On an abdominal CT scan, colonic-type intussusception in which a segment of colon telescopes into the adjacent segment of colon was strongly suspected, but the leading point was unclear. There was ascites in the Douglas pouch and she had peritoneal sign. Since a possibility of shifting to strangulation ileus or some organic disease which might cause intussusception could not be ruled out, an emergency operation was thus performed. Laparotomy disclosed colonic-type intussusception in which the transverse colon had telescoped into the transverse colon. Maneuver reduction was possible, but we selected right hemicolectomy. Because a tumor was felt around the leading point of intussusception and the mesenteric lymph nodes had also swollen, suggesting the involvement of some organic disease. Histopathology revealed no malignant findings ; only intussusception and swelling of the bowel wall were identified. Accordingly, idiopathic colonic intussusception was diagnosed.
As idiopathic colonic intussusception in adults is extremely rare, we present this case, together with a review of the literature.
