Peroral endoscopic myotomy (POEM) is a novel endoscopic technique for the treatment of achalasia and other esophageal motility disorders. Initially, it was introduced to the world by Inoue et al. in 2008.7 Thereafter; it was rapidly disseminated because of low invasiveness, higher efficacy and technical novelty. The steps of performing POEM include mucosal incision, submucosal tunnel creation, myotomy and closure of the incision. Mucosotomy (2.8%) is the most common adverse event in patients undergoing POEM.8 It can be due to excessive use of cautery because bleeding points could not be seen clearly with white light during active ooze. RDI will help in early recognition of the bleeding points, thus prompt hemostasis. Bleeding during POEM is not very uncommon(0.5-0.7%).9 Early recognition of bleeding points and quicker hemosasis help in decreasing complications. The utility of RDI in the peroral endoscopic myotomy is not studied so far to our knowledge. Hence in this study we would like to look into the utility of red dichromatic imaging in per-oral endoscopic myotomy.
