The outcome of laparoscopic Heller myotomy without antireflux procedure in patients with achalasia.

We retrospectively reviewed 30 patients with achalasia (18 males, 12 females) undergoing laparoscopic Heller myotomy without antireflux procedure to determine relief of dysphagia and prevalence of postoperative gastroesophageal reflux. Preoperative symptoms were obtained by history alone before 1996 and by standardized questionnaire after September 1996. Twenty-nine patients (97%) had dysphagia, 22 patients (73%) had regurgitation, 21 patients (70%) had weight loss, 7 patients (23%) had heartburn, and 4 patients (13%) had nocturnal aspiration. The first 3 patients were done thoracoscopically, with the subsequent 27 patients performed laparoscopically; 4 cases (13%; 1 thoracoscopic and 3 laparoscopic) were converted. The mean postoperative stay was 1.9 days (1-6 days). One patient underwent repeat laparoscopic myotomy for persistent dysphagia. Twenty-eight patients (93%) were available for follow-up. Patients were asked on a standardized questionnaire to grade their relief of dysphagia, regurgitation, and heartburn. Good to excellent relief of dysphagia was obtained in 25 patients (89%), whereas 3 patients (11%) continued to have significant dysphagia postoperatively. Twenty-four patients (86%) had little or no regurgitation. Four patients (14%) had frequent regurgitation. Twenty-four patients (89%) reported little or no heartburn. Three patients (11%) reported significant postoperative heartburn. Laparoscopic Heller esophagomyotomy without antireflux procedure provides excellent symptomatic relief of dysphagia in patients with achalasia. Early follow-up suggests that minimal occurrence of symptomatic postoperative reflux can be achieved without performing an antireflux procedure.
