Small bowel intussusception caused by a serrated adenoma: a case report

The case was a 17-year-old young woman with a one-year history of recurrent abdominal pain and discomfort. B-scan ultrasonography identified intussusception and contrast-enhanced computed tomography of the pelvis revealed volvulus. A laparoscopic procedure was planned to identify the reason for the intussusception and obstruction. Intraoperatively, the intussusception was found to be caused by a cauliflower-shaped polypoid tumor measuring approximately 4x3cm. Postoperative pathological examination identified the tumor to be a traditional serrated adenoma of the small intestine, which is rare and has atypical clinical manifestations. If unexplained abdominal pain or gastrointestinal bleeding occurs and an abdominal mass cannot be accurately located, laparoscopic or open surgery should be performed immediately. Early surgery is the most effective and reliable way of securing a prompt diagnosis and a favorable prognosis.
