Preoperative diagnosis of Meckel's diverticulum by pertechnetate scan and laparoscopic resection.

Acute lower gastrointestinal hemorrhage in a 17-year-old boy was caused by a Meckel's diverticulum 1 day after ingestion of 500 mg acetylsalicylic acid. After conservative treatment of the bleeding, the diverticulum was diagnosed in the free interval by technetium pertechnetate scintigraphy, which showed an accumulation in the right lower quadrant simultaneously with the accumulation in the gastric mucosa. Elective explorative laparoscopy confirmed the diverticulum, and the resection was performed by laparoscopic means. Histology showed gastric-type mucosa in the diverticulum. The treatment of choice for Meckel's diverticulum, when it is diagnosed preoperatively or during laparoscopy, is laparoscopic resection.
