The superiority of blue-light imaging and narrow-band imaging over white-light imaging in the detection of proximal colonic lesions
I read with interest the article by Leung et  al1 entitled “Blue-light imaging or narrow-band imaging for proximal colonic lesions: a prospective randomized tandem colonoscopy study.” The aim of this study was to evaluate and compare the efficacy of blue-light imaging (BLI) and narrow-band imaging (NBI) in detecting proximal colonic lesio ns and minimizing miss rates, in comparison with white-light imaging (WLI). The findings of the authors indicate that both BLI and NBI outperformed WLI in detecting proximal colonic lesions. (Source: Gastrointestinal Endoscopy)

Does indomethacin reduce the risk of thromboembolic events in patients undergoing ERCP?
We read with interest the article by Tien et  al,1 “Impact of direct-acting oral anticoagulants and warfarin on postendoscopic GI bleeding and thromboembolic events in patients undergoing elective endoscopy.” The authors reported their retrospective cohort study, which compared bleeding and thrombosis risk in the 30 days after endoscopy b etween warfarin and direct oral anticoagulant (DOAC) groups. They concluded that the percentage of postprocedural thromboembolic events (TE) was 2.3% in the DOAC group and 2.6% in the warfarin group. (Source: Gastrointestinal Endoscopy)

Response
We thank Dr Li1 for identifying the errors in Table  1 of our study "Blue-light imaging or narrow-band imaging for proximal colonic lesions: a prospective randomized tandem colonoscopy study."2 On further examination of the data, we found that some numbers were truncated inappropriately when rounded to 1 decimal place. However, we believe that these errors would not affect the overall results because all statistical analysis results remained unaffected. We have provided an updated version of Table 1 as shown here.

Endoscopic techniques to reduce recurrence after EMR of large nonpedunculated colorectal polyps
We congratulate Radadiya et  al1 on their recent study comparing various EMR techniques for large nonpedunculated colorectal polyps by using indirect pairwise comparison. However, their study included observational studies and randomized control trials (RCTs), which limits the ability to draw conclusions. In support of this t opic, we performed a network meta-analysis of RCTs comparing various margin ablation techniques after EMR—snare tip soft coagulation (STSC) and argon plasma coagulation (APC)—with conventional EMR (CEMR) and underwater EMR (UEMR) to treat large nonpedunculated colorectal polyps.

Response
We appreciate the letter from Pasam et  al1 in response to our article2 in Gastrointestinal Endoscopy. The authors included only randomized controlled trials, as opposed to our analysis,2 where we included both observational studies and randomized controlled trials to provide a more comprehensive review. Our analysis did not include the trials by Rex et al3 and Rodríguez Sánchez et al4 because they were published after our search period until January 12, 2023. Because our study inclusion criteria for polyps were size ≥1.5 cm, we also did not include the 2019 study by Yamashina et al. (Source: Gastrointestinal Endoscopy)

Improving colonoscopy quality: growing evidence to support adenomas per colonoscopy as a standard quality indicator
Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer death in the United States, with nearly 150,000 individuals with diagnoses of CRC and an estimated 53,200 CRC deaths in 2020.1 CRC screening has been effective at reducing the incidence and mortality of CRC by an estimated 30% to 60%, and tremendous efforts have been aimed at improving screening rates. Screening by colonoscopy is estimated to decrease CRC incidence and mortality by 69% and 68%, respectively. (Source: Gastrointestinal Endoscopy)

We sincerely thank Wu et  al1 for their interest in our article entitled “Impact of direct-acting oral anticoagulants and warfarin on postendoscopic GI bleeding and thromboembolic events in patients undergoing elective endoscopy.”2 We are pleased that their study has found concordant results of thromboembolic events. O ur ERCP cohort was too small for subgroup analysis and did not include indomethacin data. As such, the size of the authors’ ERCP cohort of individuals who had received antithrombotic agents is impressive and fills a current gap in the literature. (Source: Gastrointestinal Endoscopy)
