Achalasia after bariatric Roux-en-Y gastric bypass surgery reversal

Achalasia is a rare esophageal motility disorder that is characterized by a loss of peristalsis in the distal esophagus and failure of lower esophageal sphincter relaxation. The risk of developing esophageal motility disorders, including achalasia, following bariatric surgery is controversial and differs based on the type of surgery. Most of the reported cases occurred with laparoscopic adjustable gastric banding. To our knowledge, there are only three reported cases of achalasia after Roux-en-Y gastric bypass and no reported cases after revision of the surgery. We present a case of a 70-year-old female who had a previous history of Roux-en-Y gastric bypass with revision. She presented with persistent nausea and regurgitation for one month. Esophagogastroduodenoscopy showed a dilated esophagus without strictures or stenosis. A barium study was performed after the endoscopy and was suggestive of achalasia. Those findings were confirmed by a manometry. The patient was referred for laparoscopic Heller’s myotomy.
