Mini-sized MCE for Better Examination of UGI and Small Bowel

A mini-sized MCE highlighted with a diameter of 9.5mm, a length of 24.5mm, and a weight of 3.0g has been developed. This new type of MCE is approximately 0.6 times the conventional MCE (27mm\*11.8mm) in volume and weight, and it is the smallest CE among all the reported capsules. Thus, this pilot study was conducted to clarify whether the mini-sized MCE can further optimize the process of swallowing the capsule and to verify whether the smaller size of the capsule will have influence on the examination procedure of the upper gastrointestinal tract and small intestine.
