Hyperplastic polyp of the ileum causing intestinal intussusception

Abstract

In this study, the management of an adult patient with a mechanical small bowel obstruction caused by intussusception due to hyperplastic polyp is presented. A 25-year-old man presents to the emergency department for abdominal pain accompanied by nausea and vomiting. In the abdominal examination, the patient had sensitivity in all abdominal quadrants. Contrast-enhanced abdominal computed tomography (CT) showed enlargement of the intestinal loops, air-fluid levels, and intertwined intestinal segments in the pelvic region. On exploration with a midline incision, it was observed that the 40-cm ileal segment, starting 70 cm proximal to the ileocecal valve, was invaginated into the distal ileal segment with its mesentery. After 40 cm ileal resection, bowel reconstruction was performed with a side-to-side anastomosis with a linear stapler. The patient was discharged on the seventh postoperative day without any complications. In the histopathological evaluation of the resection material, there was a hyperplastic polyp measuring 20 × 15 mm. According to the pathology result, no additional intervention was considered for the patient.
