“…Diagnosis of Meckel’s diverticulum might be sort of challenging, and traditional diagnostic approaches usually include ultrasonography, CT scan, magnetic resonance imaging (MRI), and Meckel’s ECT, but with relatively low detecting rate, thus in some cases finally leads to diagnostic laparoscopy ( 5 ). Previous small sample pilot studies raised possibility and advantage of capsule endoscopy in identifying bleeding Meckel’s diverticulum when conventional modalities (gastroscopy, colonoscopy, CT and Meckel’s ECT) did not show any lesion, in which cases, either a double-duct sign, with or without bleeding was discovered, indicating capsule endoscopy as an effective and promising modality which can potentially be of added value in the diagnosis, especially bleeding, of Meckel’s diverticulum in the future ( 9 , 10 ). Moreover, in recent years, as development of double balloon enteroscopy, Meckel’s diverticulum would also be helpful, as in our case, specific refined structure could be well observed and even biopsied under enteroscopy was possible, providing a new approach of Meckel’s diverticulum diagnosis and thus raising positive rate of diagnostic laparoscopy.…”
