Peroral endoscopic myotomy (POEM) has become a popular treatment for esophageal achalasia and other esophageal motility disorders. However, its efficacy and safety in elderly patients are unclear. To clarify that, we reviewed the medical records of patients who underwent POEM in our hospital. A total of 11 patients who underwent POEM for esophageal achalasia (n = 10) and jackhammer esophagus (n = 1) were included. Procedural success, defined as the completion of an esophageal and gastric myotomy, was 100%. Clinical success, defined as an Eckardt score of 3 or less, without the use of additional treatments at 2 months, was 100%. The median Eckardt score significantly decreased after the POEM (baseline vs. 2 months after POEM; 7 (2-8) vs. 0 (0-1), p < 0.01). In the second and third years, the cumulative treatment effect maintenance rate was 88.9%. All patients taking antithrombotic agents had safe operations with the temporary discontinuation of these agents. There were four adverse events (two pneumoperitoneum, one mucosal injury, and one pneumonia), all of which improved with fasting or antibiotics. In conclusion, POEM is an effective and safe treatment for esophageal achalasia and achalasia-related diseases in patients aged 75 years and over.
