A Pilot Study of Sequential Capsule Endoscopy Using MiroCam and PillCam SB Devices with Different Transmission Technologies

Abstract

Sequential capsule endoscopy with the MiroCam and PillCam SB produced slight but nonsignificant increases in the diagnostic yield, and the two capsules did not exhibit electrical interference. A larger trial is necessary for elucidating the usefulness of sequential capsule endoscopy.

A multicenter, prospective, randomized comparison of a novel signal transmission capsule endoscope to an existing capsule endoscope

“…In each case, both capsules were retained and thus, it is uncertain if the MC had been the lead capsule in these cases whether the MC would have been retained as well. Two prior published studies involving MC demonstrated no cases of MC capsule retention 3,11 . Although some of this may be as a direct result of fortuitous patient selection or small sample sizes in these prior studies, one putative explanation may be the smaller external dimensions of the MC capsule compared to the PC (Table 2).…”

The Current Main Types of Capsule Endoscopy

“…The pilot study of sequential capsule endoscopies using MiroCam and PillCam showed complete examination rate 83.3 % in MiroCam and 58.3 % in PillCam (p = 0.031) [68]. Diagnostic yields for MiroCam and PillCam were 45.8 % and 41.7 % (p [ 0.05), respectively.…”

“…Secondly, the CMOS image sensor was designed to minimize power consumption, and thirdly, the telemetry chip and image sensor were combined on one chip to reduce the current required for fan-out between chips. With this advantage, the capsule operation time prolonged up to 11 h only with two usual silver oxide batteries, and thereby, MiroCam improves the complete ratio to explore the entire small bowel [68].…”

The Role of Capsule Endoscopy in the Diagnosis of Crohn's Disease

“…The video images (60,000-100,000 pixels per one image) are taken at 2-3 frames per second and transmitted to the data recorder on patient's belt, so about 50,000 images are stored for 8-11 hours of battery life, transferred to computer, and interpreted. There is no difference of the diagnostic yield between two capsule endoscopes available in Korea [10].…”
