Mo1206 Detection of Duodenal Papilla and Reading Time Using a New System of Small Bowel Capsule Endoscopy: Performance Comparison of SB2 and SB3

Background/Aims. Capsule endoscopy (CE) is a noninvasive test for diagnosing small bowel disorders. However, several studies reported that the CE-based visualization is suboptimal. This study, the first to use two CEs simultaneously, aimed at evaluating the diagnostic ability of dual CE. Methods. Dual CE procedures were prospectively conducted. All patients completed bowel cleansing 2 hours before examination. Subsequently, they simultaneously swallowed two capsules: MiroCam (IntroMedic, Seoul, Korea) and PillCam SB3 (Medtronic, Minneapolis, USA). We assessed the completeness and feasibility of small bowel examination and the detection rate of duodenal papilla and diagnostic yield. Results. Twenty consecutive patients who underwent complete small bowel examination with dual CE were enrolled in the study. The mean time of small bowel passage was 245 ± 99 min. Dual CE examination increased the duodenal papilla detection rate to up to 75% (versus PillCam SB3 alone (P=0.031) and MiroCam alone (P=0.063)) and overall diagnostic yield to up to 70% (P=0.063) in comparison to single CE. Adverse events or electrical interference during data transmission between the two capsule endoscopes were not detected. Conclusions. In this study, we found that dual CE enhances diagnostic accuracy and could increase the diagnostic power of existing CE systems using simply applicable methods. This trial is registered with KCT0002541.

Purpose. PillCam SB2 capsule endoscopy, an upgraded version of widely used SB capsule endoscopy, was examined for its performance by comparing with SB.Methods. Examinees with various indications were enrolled for SB2 capsule endoscopy; subjects were also enlisted for the old SB capsule endoscopy. Number of photo images containing papilla of Vater was counted. Shape of the papilla seen in each image was evaluated by scoring 3 (fully observable papilla), 2 (more than half outline), or 1 (less than half outline) points. Images obtained from SB and SB2 were also subjectively compared; resolution and brightness were scored by six experienced endoscopists.Results. Baseline characteristics of two study groups (n=30each) were not significantly different. Number of images of the papilla revealed to show similar results between SB (3.1±1.1, range 1~5) and SB2 (3.1±1.5, range 1~8) (P=0.62). The maximum points of outline of papilla evaluated from each subject were also similar between two groups. New SB2 revealed to be superior to SB in terms of resolution but not significantly different in brightness.Conclusion. Our study showed that superiority of SB2 over SB is rather marginal on examining duodenal papilla.

Abstract Background Reducing the reading time of capsule endoscopy films is of high priority for gastroenterologists. We report a prospective multicenter evaluation of an “express view” reading mode (Intromedic capsule system). Methods Eighty-three patients with obscure gastrointestinal bleeding were prospectively included in 10 centers. All patients underwent small-bowel capsule endoscopy (Intromedic, Seoul, Republic of Korea). Films were read in standard mode, then a second reading was performed in express view mode at a second center. For each lesion, the precise location, nature, and relevance were collected. A consensus reading and review were done by three experts, and considered to be the gold standard. Results The mean reading time of capsule films was 39.7 minutes (11 – 180 minutes) and 19.7 minutes (4 – 40 minutes) by standard and express view mode, respectively (P < 1 × 10 – 4). The consensus review identified a significant lesion in 44/83 patients (53.0 %). Standard reading and express view reading had a 93.3 % and 82.2 % sensitivity, respectively (NS). Consensus review identified 70 significant images from which standard reading and express view reading detected 58 (82.9 %) and 55 (78.6 %), respectively. The informatics algorithm detected 66/70 images (94.3 %) thus missing four small-bowel angiodysplasia. Conclusion The express view algorithm allows an important shortening of Intromedic capsule film reading time with a high sensitivity.
