A rare case of bowel intussusception due to adenocarcinomatous polyp in a 14 yearold child: case report Ahmad Sankari Tarabishi1, Ziad Aljarad2, Baraa Shebli1, Ahmad Humam Masri3, Rami Anadani1, Muhammad Besher Shabouk1* and Mazen Trissi4

Abstract Background: Intussusception 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. Conclusions: Intussusception 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. Keywords: Childhood intussusception, Adenocarcinoma, Jejuno-jejunal invagination, Case report

Background Intussusception is a form of intestinal obstruction in which a segment of the bowel prolapses into a more distal segment [1]. It typically occurs from age 6 to 18 months. After 2 years of age, the incidence of intussusception declines. Only 30% of all cases occur in children older than 2 years old [2]. The exact mechanism of intussusception remains obscure in 90% of the cases [3], but an organic lesion may serve as a lead point in * Correspondence: [email protected] 1 Faculty of Medicine, University of Aleppo, Aleppo, Syria Full list of author information is available at the end of the article

initiating its process. Polyps are among the possible precipitating factors [4]. Treatment of intussusception includes enemas, surgical reduction, and surgical resection, however, cases in this age should only be treated with surgical resection [5]. We present in this case a 14-year-old male who was diagnosed with jejuno-jejunal intussusception caused by a polyp that turned out to be an adenocarcinoma.

Case presentation A 14-year-old male was admitted to the hospital with complaints of colicky abdominal pain and severe emesis.
