Double intussusception secondary to Meckel's diverticulum in a seventeen-year-old female: a case report.

Meckel's diverticulum (MD) is the most common congenital malformation of the gastrointestinal tract. It rarely presents in adults and is usually asymptomatic. Attention to clinical history, examination and imaging studies are crucial for a successful diagnosis. A 17-year-old female presented with vomiting and acute peri-umbilical abdominal pain. Ultrasound examination showed an intussusception measuring 3.2cm in diameter and over 8cm in length. Exploratory laparoscopy showed two ileal intussusceptions. The first was reduced via laparoscopy; the second appeared suspicious for MD and ultimately required a mini-laparotomy for reduction and resection of the MD. Ultrasonography is a useful modality in the presence of perforation, occlusion, hemorrhage, neoplasia, or fistula and avoids exposure to radiation. Laparoscopic or laparoscopic-assisted mini-laparotomy is the route for the resection of MD. The choice depends on the clinical presentation and surgeon expertise. A careful history and physical examination are vital factors in diagnosis and treatment MD.
