Aim: To investigate the safety and efficacy of peroral endoscopic myotomy (POEM) for achalasia in patients aged ≥ 65 years.
Methods: From November 2011 to August 2014, 15 consecutive patients (aged ≥ 65 years) diagnosed with achalasia were prospectively recruited and all underwent POEM at our institution. Eckardt score, lower esophageal sphincter (LES) pressure, esophageal diameter, SF-36 questionnaire, and procedure-related complications were used to evaluate the outcomes.
Results: All 15 patients were treated successfully by POEM, with a median operation time of 55 min. Median myotomy length was 10 cm. Three patients underwent circular myotomy and 12 full-thickness myotomies. Symptoms remitted in all cases during post-POEM follow-up of 6-39 mo. Eckardt score reduced significantly (pre-operation vs post-operation: 8.0 vs 1.0, P < 0.05). Median LES pressure decreased from 27.4 to 9.6 mmHg (P < 0.05). Median diameter of the esophagus was significantly decreased (pre-operation vs post-operation: 51.0 mm vs 30.0 mm, P < 0.05). Only one patient had reflux, which was resolved with oral proton pump inhibitors. No serious complications related to POEM were found. The quality of life of the 15 patients improved significantly after POEM.
Conclusion: POEM is a safe and effective technique for treatment of achalasia in patients aged ≥ 65 years, with improvement in symptoms and quality of life.
