Laparoscopic Heller myotomy with Dor fundoplication for esophageal achalasia treatment after distal gastrectomy and Billroth-II reconstruction.

Laparoscopic Heller myotomy with Dor fundoplication is the standard surgical treatment for esophageal achalasia. However, there are few reports on the use of this method after gastric surgery. We report a case of a 78-year-old man who underwent laparoscopic Heller myotomy with Dor fundoplication for achalasia after distal gastrectomy and Billroth-II reconstruction. After the intraabdominal adhesion was sharply dissected using an ultrasonic coagulation incision device (UCID), Heller myotomy was performed 5 cm above and 2 cm below the esophagogastric junction using the UCID. To prevent postoperative gastroesophageal reflux (GER), Dor fundoplication was performed without cutting the short gastric artery and vein. The postoperative course was uneventful, and the patient is in good health without symptoms of dysphagia or GER. Although per-oral endoscopic myotomy is becoming the mainstay of treatment for achalasia after gastric surgery, laparoscopic Heller myotomy with Dor fundoplication is also an effective strategy.
