What is Best investigation to diagnose Meckel&;s diveiculum? and explain in detail?
.* Technetium (Tc99) radioisotope scan is very useful (90-95% accuracy). Ninety per cent of heterotrophic gastric mucosa can be identified in Meckel's diveiculum by radioisotope study. It can detect Meckel's divei-culum with minimal bleeding also (0.1 ml/minute). So it is very useful investigation in children presenting with bleeding. * X-ray abdomen to see complications like obstruction, perforation. * Laparoscopy is very useful. * Enteroclysis/small bowel enema under fluoroscopy may show the Meckel's diveiculum. It is probably the most accurate investigation. ref:SRB&;s manual of surgery,ed 3,pg no 798
