Peroral Endoscopic Myotomy

Abstract

a chalasia Presents as a Rare Disorder, affecting only 0.3-1.63 per 100,000 adults yearly, worldwide (Sadowski, ackah, Jiang, & Svenson, 2010). In the United States, it is estimated that 20,000-40,000 patients are affected by it, occurring equally amongst genders (Vaezi, Pandolfino, yadlapati, Greer, & Kavitt, 2020) with no racial correlation (Brindise, Khashab, & El abiad, 2021). Classic symptoms of achalasia include heartburn, dysphagia, regurgitation (Brindise et al., 2021), chest pain, and weight loss (Chadalavada, Thota, Raja, & Sanaka, 2020). achalasia is the leading indication for performance of peroral endoscopic myotomy to alleviate its symptoms, more frequently referred to by the acronym "POEM" (Chadalavada et al., 2020). POEMs are increasingly practiced worldwide since its original advent (Fajardo, Petrov, Bakhos, & abbas, 2020). Achalasia TypesThe Chicago classification divides achalasia into three subtypes (Pandolfino et al., 2008). achalasia Type I is characterized by aperistalsis with absence of panesophageal pressurization (Inoue et al., 2018), and it is the
