The laparoscopic cardiomyotomy (Heller) with Dor type anterior fundoplication is accepted for treatment of esophageal achalasia. Between December 1994 and December 1998, 21 patients with esophageal achalasia underwent laparoscopic Heller's operation with Dor's antireflux procedures after preoperative assessment which involved radiological, endoscopic and manometric investigations. Results were evaluated on the basis of our experiences and postoperative investigations. There were no intraoperative complications. Operating time was 40-90' (mean 65'). Conversion to laparotomy was not required. One patient had postoperative stenosis, and another had esophageal perforation which was treated. Postoperative manometry in all patients showed a decreased lower esophageal sphincter pressure. Based on the obtained results it could be concluded that cardiomyotomy with Dor fundoplication through a laparoscopic approach leeds to good functional results and seems effective and safe procedure in the treatment of esophageal achalasia.
