Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract. Histologically, it is a true diverticulum comprising all four layers of the intestinal tract. The complications associated with Meckel's diverticulum include bleeding, bowel obstruction, and intussusception. Torsions are an extremely rare complication. The patient was a 15-year-old boy who presented to the emergency department with acute-onset lower abdominal pain and was admitted to the hospital for a follow-up of abdominal pain due to nonspecific imaging findings. The symptoms of the patient worsened 12 hours after admission, and he underwent emergency laparoscopic surgery. A large Meckel's diverticulum with torsion and necrosis was observed 30 cm proximal to the ileocecal valve. The diverticulum was twisted around the base of the neck. Subsequently, wedge resection of the small intestine, including the diverticulum, was performed. Stem torsion is a rare complication of Meckel's diverticulum. As definitive preoperative diagnosis was difficult to obtain through imaging studies, early laparoscopic surgery was considered effective.
