{Reference Type}: Case Reports {Title}: Meckel's diverticulum is a rare cause of mechanical ileus in adults. {Author}: Finne KF;Schucany A; {Journal}: Ugeskr Laeger {Volume}: 186 {Issue}: 17 {Year}: 2024 Apr 22 暂无{DOI}: 10.61409/V10230632 {Abstract}: Meckel's diverticulum is the most common congenital gastrointestinal defect with a prevalence of 2%. It is mostly asymptomatic and it rarely causes acute abdomen in adults. In this case report, a 28-year-old male with no previous abdominal surgery presented with clinical symptoms of small bowel obstruction. Surgery revealed a Meckel's diverticulum adherent to the abdominal wall, causing internal herniation with small bowel obstruction. The diverticulum was openly resected and no post-operative complications occurred. Laparoscopy seems safe, and surgical removal of the symptomatic Meckel's diverticulum is recommended.
