Abstract

Serrated lesions (SLs) including traditional serrated adenomas (TSA), large hyperplastic polyps (HP) and sessile serrated lesions (SSLs) are associated with high incomplete resection rates. Margin ablation combined with EMR (EMR-T) has become routine to reduce local recurrence while cold snare polypectomy (CSP) is becoming recognized as equally effective for large SLs. Our aim was to evaluate local recurrence rates (LRR) and the use of margin ablation in preventing recurrence in a retrospective cohort study. Patients undergoing resection of ≥15 mm colorectal SLs from 2010-2022 were identified through a pathology database and electronic medical records search. Hereditary CRC syndromes, first follow-up > 18 months or no follow-up, surgical resection were excluded. Primary outcome was LRRs (either histologic or visual) during the first 18-month follow-up. Secondary outcomes were LRRs according to size, and resection technique. 191 polyps in 170 patients were resected (59.8% women; mean age, 65 years). The mean size of polyps was 22.4 mm, with 107 (56.0%) ≥20 mm. 99 polyps were resected with EMR, 39 with EMR-T, and 26 with CSP. Mean first surveillance was 8.2 mo. Overall LRR was 18.8% (36/191) (16.8% for ≥20 mm, 17.9% for ≥30 mm). LRR was significantly lower after EMR-T when compared with EMR (5.1% vs. 23.2%; p = 0.013) or CSP (5.1% vs. 23.1%; p = 0.031). There was no difference in LRR between EMR without margin ablation and CSP (p = 0.987). The local recurrence rate for SLs ≥15 mm is high with 18.8% overall recurrence. EMR with thermal ablation of the margins is superior to both no ablation and CSP in reducing LRRs. [ABSTRACT FROM AUTHOR]

392. Update on Difficult Polypectomy Techniques.

Abstract

Endoscopists often encounter colon polyps that are technically difficult to resect. These lesions traditionally were managed surgically, with significant potential morbidity and mortality. Recent advances in endoscopic techniques and instruments have allowed endoscopists to safely and effectively remove colorectal lesions with high technical and clinical success and potentially avoid invasive surgery. Endoscopic mucosal resection (EMR) has gained acceptance as the first-line therapy for large colorectal lesions. Endoscopic submucosal dissection (ESD) has been reported to be associated with higher rate of en bloc resection and less risk of short-time recurrence, but with an increased risk of adverse events. Therefore, the role of colorectal ESD should be restricted to lesions with high-risk morphologic features of submucosal invasion. In this article, we review the recent literature on the endoscopic management of difficult colorectal neoplasms. [ABSTRACT FROM AUTHOR]

Abstract

Background: The efficacy of screening colonoscopy depends on adequate adenoma detection. Operating behind schedule (i.e. "running late") might impose time pressure and affect adenoma detection. The aim of the study was to examine whether there is an association between procedural delay and adenoma detection rate (ADR). Methods: We retrospectively identified individuals who underwent an elective outpatient colonoscopy at an academic medical center between October 2011 and March 2012. We extracted information regarding procedure details, and patient and polyp characteristics. Procedure delay was defined as the time elapsed between the scheduled and actual procedure start times. We calculated the ADR for each 15-minute delay interval and for each quartile of procedure delay for individual endoscopists. Results: In total 1505 patients (mean age 61.3, 49% men) were examined by 11 endoscopists. At least one adenomatous polypwas found in 507 patients (34 %), with a mean of 0.63 adenomas per patient. Colonoscopies started at amedian 18 minutes late (IQR 3-36) and median delay times varied broadly between endoscopists from 4 minutes to 45 minutes. ADR was not affected by procedure delay and was similar across 15-minute delay intervals (P=0.101). The ADR also remained similar across quartiles of the endoscopists' delay times (from lowest to highest delay quartile: 34%, 32%, 32%, and 37%; P=0.397). Independent factors associated with increased adenoma detection included being a man, older age, surveillance colonoscopy, and the endoscopist. Conclusion: In this large multiendoscopist study we did not find that procedure delay affected adenoma detection. Even when endoscopists are behind schedule, they still perform a meticulous examination with no impact on adenoma detection. [ABSTRACT FROM AUTHOR]
