Core Tip

Core Tip: This randomized controlled trial compared the efficacy and outcomes of laparoscopic myotomy and partial fundoplication (LM-PF) with those of peroral endoscopic myotomy (POEM) for the treatment of patients with achalasia of any etiology. There were no statistically significant differences between the LM-PF and POEM groups regarding symptoms. However, the rates of reflux esophagitis were significantly higher in the POEM group. POEM and LM-PF appear to be equally effective in controlling the symptoms of achalasia, shortening length of hospital stay, and minimizing adverse events. However, POEM has the advantage of shortening anesthesia and procedure times.
