A Case of Strangulated Intestinal Obstruction Caused by Acquired Ileal Diverticulum

<b>Background:</b> Acquired ileal diverticulum is an extremely rare condition that occurs in the ileum and is caused by acquired factors. Strangulated intestinal obstruction, a life-threatening variant of bowel obstruction, is associated with exceedingly high mortality rates. Here, we present a case of acquired ileal diverticulum causing strangulated intestinal obstruction, which was treated at our hospital. <b>Case Report:</b> A 65-year-old female with no previous history of intestinal obstruction presented with acute abdominal pain. An exploratory laparotomy revealed an acquired ileal diverticulum and an internal hernia. <b>Conclusion:</b> Acquired ileal diverticulum leading to strangulated intestinal obstruction is rare. Clinicians should consider the possibility of this disease when encountering intestinal obstruction patients with no history of abdominal surgery.
