Background and study aims Some patients with dysplastic Barrett’s esophagus (BE) experience suboptimal response to radiofrequency ablation (RFA), endoscopic mucosal resection (EMR), or the combination. Cryotherapy has been used as salvage therapy in these patients, but outcomes data are limited. We aimed to assess clinical outcomes among a large cohort of patients with dysplastic BE whose condition had failed to respond to RFA and/or EMR. Patients and methods This was a retrospective cohort study of consecutive cases of dysplastic BE or intramucosal carcinoma (IMC) treated with salvage cryotherapy at a tertiary-care academic medical center. The primary goal of cryotherapy treatment was eradication of all neoplasia. The secondary goal was eradication of all intestinal metaplasia. The proportion of patients undergoing salvage cryotherapy who achieved complete eradication of dysplasia (CE-D) and metaplasia (CE-IM), as well as the time to CE-D and CE-IM were calculated. Results Over a 12-year period, 46 patients received salvage cryotherapy. All patients underwent RFA prior to cryotherapy, either at our center or prior to referral, and 50 % of patients underwent EMR. A majority of patients (54 %) had high-grade dysplasia (HGD) at referral, while 33 % had low-grade dysplasia (LGD), and 13 % had IMC. Overall, 38 patients (83 %) reached CE-D and 21 (46 %) reached CE-IM. Median time to CE-D was 18 months, median number of total interventions (RFA, cryotherapy, and EMR) was five, and median number of cryotherapy sessions was two. Conclusion Salvage cryotherapy appears safe and effective for treating BE that is refractory to RFA and/or EMR.
Medical students and educators face a myriad of complex moral disagreements and conflicts both in preclinical and clinical training environments. Inability to deal with these conflicts effectively and compassionately can lead to undesirable consequences and threaten important relationships in high-stakes healthcare environments. We suggest that the integration of moral psychology into medical education can help trainees and faculty constructively respond to behavior they may find immoral or misguided. Here we focus on the application of Moral Foundations Theory (MFT), which demonstrates how the instantaneous gut reactions which guide reactionary behavior can be categorized into six foundational categories. These categories offer psychological explanations for human behavior which can help medical trainees and professionals navigate challenging moral conflicts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
