Abstract

Background and Aims EMR is increasingly used for resection of sporadic, nonampullary duodenal adenomas (SNDAs), but there are no guidelines for the management of these lesions. The aims of this study were to evaluate the safety and efficacy of EMR exclusively for SNDAs and to determine the factors predictive of outcomes. Methods We performed a retrospective review of patients with SNDAs referred for endoscopic therapy from 2006 to 2013. The outcomes studied were successful endoscopic resection, major adverse events, early and late recurrences, and clinical remission. Results Sixty-eight patients with SNDAs were included and 51 (75%) underwent EMR. The mean adenoma size was 22.0 ± 8.9 mm. Successful resection was achieved in 49 of 51 patients (96.1%), and major adverse events were noted in 8 of 51 patients (15.7%). Early and late recurrences were noted in 25.6% and 5.2% of patients, respectively, and were treated endoscopically. Clinical remission was achieved in 89.7% of patients after a median follow-up of 15 months. Presence of villous histology was associated with increased recurrence ( P = .019), but no association of recurrence was noted with other endoscopic features or resection technique. Large adenoma size ( P = .0057) and need for intraprocedural hemostasis ( P = .006) were associated with increased adverse events, but no association of adverse events was noted with location or resection technique. Conclusions Large duodenal adenomas can be effectively managed with EMR at a referral center with experienced endoscopists. However, EMR has a significant recurrence rate, especially early recurrence, and the risk of adverse events is not negligible. Endoscopic therapy is successful in managing recurrent adenomas.

Abstract

During endoscopic surveillance and treatment in Barrett’s esophagus, the endoscopist may use a combination of tools to assist in targeting biopsies and endoscopic resections in order to diagnose and treat Barrett’s esophagus–associated neoplasia. There is a concern for subepithelial metaplasia or neoplasia in both naive and previously treated Barrett’s esophagus. Tools to characterize so-called buried disease may allow for improved detection of occult disease. Optical biopsy with volumetric laser endomicroscopy, or VLE, is based on optical coherence tomography. This technology is analogous to
