Does the PillCam SB3 capsule endoscopy system improve image reading efficiency irrespective of experience? A pilot study

Abstract

Background and study aims The aim of this study was tp compare the diagnostic efficiency of the PillCam SB3 capsule endoscopy (CE) system with the older system, PillCam SB2, taking into consideration the experience of the image reader. Patients and methods Small intestinal CE was conducted on 64 patients around May 2014 when the SB3 was introduced in our hospital. Data obtained from 20 patients (SB2: 10 and SB3: 10) based on transit time were assessed by junior (experience: 20 images), intermediate (> 50), and expert readers (> 600). Results Reading time with the CE down to the end of the small intestine was shorter in the SB3 group for each reader (SB2 vs. SB3: junior, 40.2 ± 10.1 vs. 23.7 ± 6.7 [ P = 0.0009]; intermediate, 21.4 ± 4.9 vs. 10.3 ± 2.9 [ P = 0.0003]; expert, 23.2 ± 5.6 vs. 11.1 ± 2.9 min [ P = 0.0002]). Interpretation agreement rates between the findings by junior and intermediate readers and those by the expert reader were 84.6 % and 92.3 %, respectively. For the junior reader, rates of agreement using the SB2 and SB3 systems with those by the expert reader were 85.7 % and 83.3 %, respectively; no significant difference was noted between the two systems. Similarly, for the intermediate reader, the respective agreement rates using the SB2 and SB3 systems were 85.7 % and 100 %, respectively. Conclusions The PillCam SB3 reduces the time burden on readers irrespective of their experience.

Capsule endoscopy for small‐intestinal disorders: Current status

“…24,25 In the current version of PillCam software (Rapid version 8.3), manual and automatic modes have been replaced by review mode, and Rapid version 8.3 enables more efficient video reading as compared with a previous version. 26 Previously, we reported that the reading time using automatic mode and quickview mode was significantly shorter than that in normal mode. 20 A previous version of SBI had low sensitivity for the detection of active bleeding, 24,25,27 and was upgraded using current PillCam software (Rapid version 8.3).…”

“…The SBI mode functions by identifying red pixels on the screen, and then annotating the scroll bar automatically with a red line . In the current version of PillCam software (Rapid version 8.3), manual and automatic modes have been replaced by review mode, and Rapid version 8.3 enables more efficient video reading as compared with a previous version …”

<p>Poor Quality of Small Bowel Capsule Endoscopy Images Has a Significant Negative Effect in the Diagnosis of Small Bowel Malignancy</p>

“…Capsule reviewers achieved an agreement rate of 70%, implying that just under a third of patients had different findings between the two models of capsule. In another study by Omori et al, 10 the use of the 3rd-generation PillCam® SB3 was found to reduce the time burden for both expert and inexperienced readers. The authors propose that this was due to an improved software algorithm for adaptive frame rate and improved image resolution.…”

Capsule Endoscopy: Pitfalls and Approaches to Overcome

“…The first-generation PillCam SB capsule endoscope measures 11 × 26 mm, and both the second and third generations have the same size (Figure 7) [31,32]. The PillCam SB capsule endoscope takes two pictures per second and has a viewing angle of 140 • .…”
