Image-Enhanced Capsule Endoscopy Improves the Identification of Small Intestinal Lesions

Image-enhanced endoscopy is useful for diagnosing and identifying lesions in the gastrointestinal tract. Recently, image-enhanced endoscopy has become a breakthrough technology that has attracted significant attention. This image enhancing technology is available for capsule endoscopy, which is an effective tool for small intestinal lesions and has been applied in flexible spectral color enhancement technology and in contrast capsule like narrow-band imaging. In this field, most researchers focus on improving the visibility and detection of small intestinal lesions. This review summarizes previous studies on image-enhanced capsule endoscopy and aims to evaluate the efficacy of this technology.

Background and aim: Olympus Corporation released the texture and color enhancement imaging (TXI) technology as a novel image-enhancing endoscopic technique. We investigated the effectiveness of TXI in the imaging of serrated colorectal polyps, including sessile serrated lesions (SSLs). Methods: Serrated colorectal polyps were observed using white light imaging (WLI), TXI, narrow-band imaging (NBI), and chromoendoscopy with and without magnification. Serrated polyps were histologically confirmed. TXI was compared with WLI, NBI, and chromoendoscopy for the visibility of the lesions without magnification and for that of the vessel and surface patterns with magnification. Three expert endoscopists evaluated the visibility scores, which were classified from 1 to 4. Results: Twenty-nine consecutive serrated polyps were evaluated. In the visibility score without magnification, TXI was significantly superior to WLI but inferior to chromoendoscopy in the imaging of serrated polyps and the sub-analysis of SSLs. In the visibility score for vessel patterns with magnification, TXI was significantly superior to WLI and chromoendoscopy in the imaging of serrated polyps and the sub-analysis of SSLs. In the visibility score for surface patterns with magnification, TXI was significantly superior to WLI but inferior to NBI in serrated polyps and in the sub-analysis of SSLs and hyperplastic polyps. Conclusions: TXI provided higher visibility than did WLI for serrated, colorectal polyps, including SSLs.

Abstract Background and study aims Mycobacterium tuberculosis is often detected in the feces of patients with active pulmonary tuberculosis. However, no study has examined the small intestine using small bowel capsule endoscopy (SBCE). This study aimed to investigate intestinal abnormalities in patients with active pulmonary tuberculosis. Patients and methods SBCE was performed in sputum/feces smear-positive pulmonary tuberculosis patients. From December 2013 to November 2016, 15 patients were enrolled from a dedicated tuberculous ward. The primary outcome was intestinal abnormalities identified by SBCE. Results Fourteen patients (median age 81 years, range 29 – 91; 3 female) underwent SBCE to the terminal ileum. The video was not recorded for one patient who was excluded from the analysis. Intestinal lesions, including 5 annular ulcers in 4 patients, were observed in 64 % (9/14). In subgroup analysis, prevalence tended to be higher in patients undergoing SBCE within 1 month of anti-tuberculous therapy (P = 0.051). Distribution of small intestinal lesions tended to be distal. Four of five annular ulcers were located close to the ileocecal valve. Conclusion Prevalence of intestinal lesions in patients with pulmonary tuberculosis is higher than expected before (UMIN 000017292)
