Background: Peroral endoscopic myotomy (POEM) is a safe and effective endoscopic treatment for achalasia. However, postoperative pain management for these patients is often neglected by anesthesiologists because of the short operative time, short hospital stay and the minimally invasive nature of the procedure.
Aim: To assess the pain and sleep quality of achalasia patients receiving the POEM procedure and investigate factors that affect postoperative pain.
