Core Tip

Core Tip: Per-oral endoscopic myotomy (POEM) has proved an ideal way to treat primary achalasia in both short- and long-term but there is little evidence for achalasia related to Triple A syndrome, a rare disease. Herein, we enrolled three patients and performed POEM on them. During the following 2 years, we evaluated them by Eckardt score, barium swallowing test and Esophagogastroduodenoscopy. As a result, they all improved in all aspects.
