Background: Evaluation of laparoscopic Heller myotomy(LHM) without fundoplication in the treatment of esophageal achalasia , and assessment of its safety and effectiveness on the short and long-term results. Patients and Methods: In this prospective study, 21 patients were included in the study were reviewed including patient demography, clinical manifestations, preoperative investigations, operative procedure, intraoperative, postoperative complications, and postoperative follow up. AII patients enrolled in the study underwent laparoscopic Heller myotomy without Dor fundoplication. Mean age was 42 years, average operative time was (70-110) minutes, no patient was lost to follow up period. All patients were operated on in our surgery department. Results: 21 patients in our study were diagnosed to have achalasia by means of patient symptomatology, full investigatory methods in the form of upper GI endoscopy, esophageal manometry, 24-h PH monitoring, upper contrast series.(Barium swallow). All the 21 patients underwent laparoscopic Heller myotomy without Dor fundoplication, 2 female patients had esophageal perforations, one of them after pneumatic dilation , the other during laparoscopic myotomy. Both patients had intraoperative suture repair during laparoscopic myotomy. All patients had satisfactory postoperative course with no recurrence of dysphagia, and no evidence of gastroesophageal reflux.19 patients were discharged on the 2nd and 3rd postoperative days, and the 2 patients who presented with esophageal tear were discharged after 1week. Conclusion: Laparoscopic Heller myotomy without fundoplication seems to be an effective surgical technique as compared to laparoscopic Heller myotomy with Dor fundoplication , with similar advantages, and efficacy. It provides both short and long-term symptomatic relief, with short hospital stay, and less complication rate. Key words: Laparoscopic Heller myotomy, achalasia, fundoplication.
