A rare case of bowel intussusception due to adenocarcinomatous polyp in a 14 year-old child: case report.

backgroundIntussusception is a form of intestinal obstruction in which a segment of the bowel prolapses into a more distal segment. It is an uncommon condition in children older than 2 years and causes intestinal obstruction. On the contrary of adult intussusception, childhood intussusception does not usually happen on a lead point of a malignant organic lesion. CASE PRESENTATION: A 14-year-old male presented with complaints of heavy, bilious emesis and periumbilical colicky pain. Ultrasonography showed a dilated intestinal loop with absent bowel movement. CT scan revealed two masses in the abdomen. We performed an exploratory laparotomy that revealed invaginated intestines and showed a polyp near the area of interest. Necrotic segments and the polyp were removed and examined pathologically. Pathology showed adenocarcinoma in the polyp. After surgery, the general condition of the patient was normal and no complications occurred.

conclusionsIntussusception mainly occurs during infancy and early childhood. Mostly it is an idiopathic ileo-colic invagination. In our case, the patient had a jejuno-jejunal intussusception in his late childhood, and the lead point was an adenocarcinomatous polyp, which is rare in children. Amongst the many types of treatment, we chose surgical resection because of patient's age.
