Education and training in NOTES: a systematic review.

ABSTRACT

INTRODUCTION: Since the first published work on natural orifice translumenal endoscopic surgery (NOTES) a decade ago, progress has been made in the domain of education and training, although questions posed by the original White Paper remain. This article aims to review the current status of education and training in NOTES. METHODS: A review of the literature was conducted to evaluate the following (1) What are the current training methods/modalities used for NOTES; what is the level of evidence to support their use? (2) How has NOTES clinical training been quantified; what is the evidence relating to performance of different NOTES operators? (3) What clinical NOTES training programs have been established and what are the wider training needs? RESULTS: A total of 25 studies were included 11 nonanimal studies, 8 animal studies, and 6 descriptions of education programs. Several animal and simulator models demonstrated construct validity, but no study showed human predictive validity. Logarithmic learning curves in animal models demonstrate 10 to 15 cases achieving a proficiency level. Current trends are that gastroenterologists prefer it for diagnostic and basic procedures, whereas surgeons prefer it for complex therapeutic cases. CONCLUSION: The development of a new specialty is intriguing but currently unviable. Training programs have been initiated, but information is limited; the common theme is surgeons receiving endoscopic training. Despite the research done, our knowledge of training and educating in NOTES procedures is limited, preventing a meta-analysis or formal review from being performed. Further research is needed to integrate NOTES into routine clinical procedure.
