Evaluating learning curves and competence in colorectal EMR among advanced endoscopy fellows: a pilot multicenter prospective trial using cumulative sum analysis.

BACKGROUND AND AIMS: Data on colorectal EMR (C-EMR) training are lacking. We aimed to evaluate C-EMR training among advanced endoscopy fellows (AEFs) by using a standardized assessment tool (STAT). METHODS: This multicenter prospective study used a STAT to grade AEF training in C-EMR during their 12-month fellowship. Cumulative sum analysis was used to establish learning curves and competence for cognitive and technical components of C-EMR and overall performance. Sensitivity analysis was performed by varying failure rates. AEFs completed a self-assessment questionnaire to assess their comfort level with performing C-EMR at the completion of their fellowship. RESULTS: Six AEFs (189 C-EMRs; mean per AEF, 31.5 ± 18.5) were included. Mean polyp size was 24.3 ± 12.6 mm, and mean procedure time was 22.6 ± 16.1 minutes. Learning curve analyses revealed that less than 50% of AEFs achieved competence for key cognitive and technical C-EMR endpoints. All 6 AEFs reported feeling comfortable performing C-EMR independently at the end of their training, although only 2 of them achieved competence in their overall performance. The minimum threshold to achieve competence in these 2 AEFs was 25 C-EMRs. CONCLUSIONS: A relatively low proportion of AEFs achieved competence on key cognitive and technical aspects of C-EMR during their 12-month fellowship. The relatively low number of C-EMRs performed by AEFs may be insufficient to achieve competence, in spite of their self-reported readiness for independent practice. These pilot data serve as an initial framework for competence threshold, and suggest the need for validated tools for formal C-EMR training assessment.

Coronary artery spasm: An often overlooked diagnosis.

Coronary vasospasm can lead to myocardial injury and even sudden cardiac death. It has generally been overlooked as a diagnosis since atherosclerosis is a more common cause of acute coronary syndromes and because of the dilemma involved in its diagnosis. A middle-aged man with a history of smoking and cocaine use presented to the emergency department with left-sided arm/chest discomfort and diaphoresis. The electrocardiogram showed anterior ST elevation and hyper-acute T waves, which completely resolved shortly after sublingual nitroglycerin was administered. Subsequent angiogram revealed a 70% focal stenosis in the mid-left anterior descending artery. Coronary vasospasm occurs more commonly in arteries with underlying atheromatous disease, although normal vessels are not excluded. Cigarette smoking and cocaine use are among the major culprits that have been implicated as risk factors for the occurrence of coronary vasospasm. Eventually, the patient had percutaneous coronary intervention of his left-anterior descending artery and remained asymptomatic.
