“…Various IEE modalities, including narrow-band imaging (NBI), blue-laser imaging, and LCI, have been developed, among which NBI and LCI are efficacious in evaluating the severity of histological inflammation in UC [20,21,[25][26][27]. IEE has been frequently used in clinical practices, including detection and characterization of sporadic colonic tumor [14][15][16][17][18][19][28][29][30][31], detection of tumor lesion, and diagnosis of histological activity, and has been recently suggested for predicting relapse risk [20,26]. We previously reported that LCI was more useful than conventional endoscopy for the visualization and evaluation of mucosal inflammation based on the mucosal color change of redness and yellowness in UC.…”

Ulcerative colitis (UC) is a chronic inflammatory bowel disease with unknown etiology. Recently, mucosal healing has emerged as an important therapeutic endpoint in UC. Linked color imaging (LCI) is a novel endoscopic system that enhances the color differences of the gastrointestinal mucosa. Our previous study emphasized the redness and yellowness of the lesion using LCI observation, which was useful for the evaluation of histological mucosal activity in UC. In this study, we aimed to evaluate the correlation between LCI observation and clinical relapse rate in UC patients. We retrospectively analyzed UC patients who underwent total colonoscopy between August 2016 and October 2018 at our facility with Mayo endoscopic scores of 0 or 1. We assessed the correlation between orange-like color lesion (defined as LCI-scarlet color lesions) and clinical relapse rate (requiring additional treatment for UC) during the 1-year follow-up period. Fifty-eight patients (22 female, 36 male; median age at diagnosis, 47.2 (18–80) years) who underwent colonoscopy were analyzed. During the 1-year follow-up period, clinical relapse was observed in 12 patients (20.1%) among which ten patients (83.3%) had an LCI-scarlet color lesions recognized by LCI. By contrast, 29 patients (63%) had no LCI-scarlet color lesions in the clinical remission group (n=46). There was a significant difference in LCI-scarlet color between the clinical relapse and remission groups, remaining significantly associated with clinical relapse. LCI findings, including an orange-like color lesion, have diagnostic implications for predicting the risk of clinical relapse in UC during the 1-year follow-up period.

“…This system makes red areas appear redder and white areas appear brighter. Therefore, it is a useful tool for recognizing color differences in the mucosa, by facilitating the detection and recognition of colorectal neoplasms [14][15][16][17][18][19].…”

“…10,11 In 2015, the American Society for Gastrointestinal Endoscopy (ASGE) suggested in its guidelines that referral services in CRC screening should have ADRs higher than 20% among women and 30% among men. 5 The European Society of Gastrointestinal Endoscopy (ESGE) guidelines, based on recent population-based studies, proposed a minimum standard ADR of 25% (7,12), which was met by the majority of endoscopists. 7 Recent studies with new advanced imaging equipments have shown even higher ADRs, inferring that, with the dissemination of these new technologies, the minimum ADR standards may become even higher in the near future.…”

“…7 Recent studies with new advanced imaging equipments have shown even higher ADRs, inferring that, with the dissemination of these new technologies, the minimum ADR standards may become even higher in the near future. 12 Several interventions, including education, raising awareness, feedback and benchmarking on colonoscopy quality have all helped to improve the ADR for colonoscopists involved in screening programs. 13,14 The other main criteria associated with ADRs are quality of the preparation, cecal intubation and the time of removal of the colonoscope in normal colonoscopies.…”

Background Colorectal cancer (CRC) is the third most common cancer among men, and the second among women worldwide. In Brazil, the incidence and mortality of CRC continues to increase. In colonoscopies, adenoma detection rates (ADRs) higher than 25% are associated linearly with better outcomes and lower rates of interval cancer. Objective To assess the colonoscopy quality indexes. Methods This is a cross-sectional retrospective study in which anatomopathological data and data regarding the colonoscopies were collected from the patient records of Hospital Moinhos de Vento, in Southern Brazil. The exams were performed by doctors from the Colorectal Service from June to August 2015. Results A total of 430 exams were included. Most patients were women (60.9% [262]), with a mean age of 56.96 years. The cecal intubation rate was of 96.7% (416). The quality of the bowel preparation was excellent or good in 92.95% (396) of the cases. The average time of removal of the colonoscope in normal exams was of 6.15 minutes. Polyps were detected in 201 patients (46.7%), and adenomas, in 125 patients (29.1%); 12 patients (2.8%) had advanced adenomas, and 6 (2.3%) had malignant neoplasms. The proximal serrated lesion detection rate (PSLDR) was of 6.7% (29). The prevalence ratio (PR) of adenomas among men was 1.78 times greater than in women (95% confidence interval [95%CI]: 1.16–2.75). The PR of adenomas among people aged 50 years or older was 2.41 times that of those under 50 years of age (95%CI: 1.43–4.06). Conclusion The data obtained are in line with international quality criteria in colonoscopy. More studies are needed to assess the ADR in the Brazilian population.
