Esophageal achalasia detected by vomiting during induction of general anesthesia: a case report

Abstract

Abstract Background Esophageal achalasia is a rare disease with a high risk of aspiration during anesthesia induction. Here, we describe our experience involving a case of undiagnosed esophageal achalasia with profuse vomiting during anesthesia induction. Case presentation A 58-year-old woman was scheduled for orthopedic surgery under general anesthesia. She vomited a large amount of watery contents during anesthesia induction, and planned surgery was postponed. After recovery from anesthesia, she informed us that she usually had to drink a large amount of water to get food into her stomach and purged watery vomit every night before sleep. However, she attributed it to her constitutional problem, not to a specific disease. She was subsequently diagnosed with esophageal achalasia and underwent Heller myotomy with Dor fundoplication before her re-scheduled orthopedic surgery. Conclusions A detailed history of dysphagia and regurgitation should be taken in preoperative examinations to prevent unexpected aspiration due to undiagnosed achalasia.
