A rare cause of obstructive defecation in a 29-year-old woman: Ileo-colo-colonic intussusception treated by subtotal colectomy with posterior rectopexy Adult intussusception is a rare clinical condition. In majority of adult cases, there is an underlying cause such as polyps or colon cancers. In the present study, a 29-year-old woman with intermittent and colicky abdominal pain, constipation, and painful defecation, accompanied with distention and sense of rectal fullness, was evaluated with computed tomography. Ileo-colo-colic intussusception was determined. Subtotal colectomy with posterior rectopexy was performed. After the surgery, she was doing well at 13-month follow-up.

INTRODUCTIONIntussusception is the invagination of an intestinal segment to the continuing part of the intestine. Usually, it is a pediatric diagnosis due to benign pathologies (1, 2). Intussusception as the most common cause of intestinal obstruction occurs most frequently in infants (3, 4). However, less than 5% of the intussusception cases are seen in adults (5). Majority of the cases in children are idiopathic, but an organic cause, such as a polyp or colonic malignancy, is usually detected as the underlying cause of intussusception in adults (6, 7). Intussusception in adults most commonly appears as enteroenteric (limited to small intestine). It has been known that colo-colonic intussusception (limited in colon and rectum, without anal protrusion) is the least common type (8). In these circumstances, colonic tumors have been regarded to be the main cause (9). However, intussusception starting from the distal ileal segments to the rectum without proven gastrointestinal malignancy can be a very rare event in adults.In this paper, we present a young female patient with obstructive defecation caused by ileo-colo-colonic intussusception.
CASE PRESENTATIONA 29-year-old woman with intermittent and colicky abdominal pain, constipation, and painful defecation, accompanied with distention and a sense of rectal fullness was hospitalized. Similar symptomatology was present for last three months. The patient was described fecal incontinence with a mass protruding from her anus during maximal discomfort. Physical examination revealed distended abdomen with mild tenderness. Patulous anus with a bulky mass protruding through the rectum mimicking prolapse was detected on rectal examination. Coronal curved multiplanar reconstruction of contrastenhanced computed tomography (CT) (Figure 1) showed bowel-within-bowel appearance of ileo-colocolic intussusception elongated from the cecum to the splenic flexure. Surgical intervention had been decided and informed consent had been received. At diagnostic laparoscopy, a dilated and partially invaginated bowel was observed. On conversion to laparotomy, ileo-colo-colic intussusception including terminal ileum and right, transverse, left, and sigmoid colon was determined. Subtotal colectomy had been initiated because all colonic segments invagin...
