Abstract
- Gastroduodenal intussusception is a rare condition caused by the prolapse of a gastric tumor with subsequent invagination of a portion of the gastric wall into the duodenum. Various gastric lesions including adenoma, lipoma, leiomyoma, hamartoma, adenocarcinoma, gastrointestinal stromal tumor (GIST), and as in our case a Peutz-Jeghers polyp, can serve as a lead point of intussusception. Only three cases of gastroduodenal intussusception secondary to a Peutz-Jeghers polyp have been reported. We experienced a case of gastroduodenal intussusception in a 36-month-old boy who presented with intermittent nonbilious vomiting, abdominal pain, and anemia. An abdominal ultrasound and contrast enhanced CT scan showed gastrointestinal intussusception and a mass-like lesion in the second portion of duodenum. A laparotomy revealed a 7x8 cm sized mass at the gastric body, which was pathologically confirmed as a Peutz-Jeghers polyp.
