Per oral endoscopic myotomy (POEM) has been a minimally invasive treatment option for patients with achalasia for the past 10 years. Although comparable to laparoscopic Heller's myotomy (LHM) in terms of efficacy, POEM has the advantages of minimal invasiveness, allowance for a longer myotomy, and the ability to perform a posterior or anterior myotomy. [1][2][3][4][5][6] After 10 years of consistent safety and efficacy, POEM is now being performed worldwide and has been increasingly used in Latin America where Chagas disease is prevalent. Reports on POEM for Chagas disease are scarce. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] POEM in Chagas disease is technically more challenging than in patients with achalasia, due to a higher rate of submucosal scarring, 21 most likely related to chronic esophagitis caused by esophageal stasis (clinical observation, unpublished data). Two recently published studies have shown that Chagas disease-related achalasia responds better to POEM. 15,22 Nonetheless,
