Meckel's diverticulum (MD) occurs in 2–3% of the population. Although the clinical, histopathologic, and radiologic features of the complications of MD are well known, the diagnosis may be difficult before surgery.CASE REPORT
Three patients (age 22–34 yr, two women) presenting with gastrointestinal (GI) bleeding of obscure origin underwent multiple endoscopic and radiologic tests including capsule endoscopy and Tc-99m pertechnetate scintigraphy before push-and-pull enteroscopy using a double-balloon technique (double-balloon enteroscopy). Double-balloon enteroscopy was performed in all three patients using oral and anal approaches to evaluate the entire intestine. In one case, MD was detected using the oral route; the diagnosis was confirmed using the anal approach. In two patients, the lumen of MD was disclosed using the anal route. No procedure-related complications occurred. Push-and-pull enteroscopy was the only nonsurgical procedure that provided a precise diagnosis. All patients underwent surgical resection of the diverticulum. In one case, ectopic gastric tissue was found histologically. No further bleeding occurred during follow-up (6–9 months).CONCLUSIONS
Keeping the low sensitivity of Tc-99m scintigraphy in the adult population in mind, double-balloon enteroscopy might be the modality of choice in young adult patients with acute recurrent GI bleeding of obscure origin and a suspected diagnosis of MD.
