Core Tip
Core Tip: This study investigated the clinical significance of lower esophageal muscularis propria (LEMP) thickness in achalasia patients. We retrospectively enrolled 82 patients who underwent peroral endoscopic myotomy (POEM) at our center. The results showed that endoscopic ultrasound-measured LEMP thickness may help diagnose achalasia and predict long-term prognosis after POEM. Patients with a thickened muscularis were typically older and had a longer disease course. Younger age and male gender were risk factors for recurrence. Achalasia was more likely to relapse after POEM in patients with a thin LEMP, although further validation is needed.
