Meckel's diverticulum is a common congenital anomaly in the small bowel. Most cases of Meckel's diverticulum are asymptomatic and are found incidentally. We herein report on a case of a 21-year-old male patient who complained of lower abdominal pain and febrile sensation with incidentally diagnosed gangrenous change of Meckel's diverticulum due to axial torsion itself. A 21-year-old man presented to our institution with acute lower abdominal pain. No accurate focus on abdominal pain such as appendicitis or diverticulitis was observed on abdominal ultrasonography and abdominal CT scan. However, the physical examination of the patient revealed the symptom of localized peritonitis with fever. Finally, laparoscopic exploration was performed to determine the cause of acute abdominal pain. During the operation, we found gangrenous change of Meckel's diverticulum with axial torsion itself and laparoscopic Meckel's diverticulectomy was performed. The patient made an uneventful recovery and was discharged on the 6th postoperative day.
