ABSTRACT: Achalasia is an uncommon primary motor disorder of the esophagus with an annual incidence of 0.8/100,000. Very few cases of coexistent Barrett’s esophagus (BE) and achalasia in patients without prior surgical myotomy or pneumatic dilation have been reported. We report the case of a 65 year old female who was diagnosed with achalasia in June 2002. Endoscopy at that time revealed biopsy-confirmed normal esophageal mucosa. The patient subsequently underwent two trials of botox injection with progressively worsening dysphagia. A repeat endoscopy two years later showed a short segment of salmon-colored mucosa in the distal esophagus which was biopsy-confirmed Barrett’s epithelium with no dysplasia. The patient eventually underwent laparoscopic Heller myotomy and Toupet fundoplication. Postoperatively, she recovered well and with significant alleviation of her dysphagia. This study reviews reported cases of coexistent achalasia and BE, and discusses possible etiologies of concurrent BE and achalasia, and implications for treatment.
