Prospective, randomized, single center study to evaluate efficacy of novel red dichromatic imaging (rdi) in achieving hemostasis during peroral endoscopic myotomy (poem): interim analysis of a pilot study

Aims To assess the reduction in total procedural time using Red dichromatic imaging (RDI) compared to white light imaging in achieving haemostasis during POEM. The use of RDI in comparison with white light imaging (WLI) in achieving haemostasis, ease of mucosal entry by using RDI when compared to WLI and psychological stress experienced by endoscopists during haemostasis treatment.
