Conclusion
upper and small bowel GI bleeding
Our study provided a safe and feasible modality for complete and consecutive visualization of UMGI tract with high tolerance and diagnostic yield, and UMGI capsule might be indicated in cases of suspected upper and small bowel GI bleeding, possibly associated with or due to the use of anticoagulant/antiplatelet or non-steroidal anti-inflammatory therapy, especially in those who are unwilling and unable to undergo traditional endoscopy. The study provided a basis for innovation of a real “mouth to anus” screening tool in the future.
