Surgical treatment of achalasia. Experience in 328 patients

Background: Patients with achalasia may require surgical treatment. Aim: To assess postoperative evolution, complications and mortality after surgical treatment of achalasia. Material and Methods: Analysis of 328 patients aged 13 to 80 years (51% females) with achalasia, operated in a period of 40 years. Open surgery was used in 165 patients and a laparoscopic modality (starting in 1994) in 163. Results: Patients subjected to open or laparoscopic surgery had similar demographic and manometric features. Mucosal injury during myotomy occurred in 20 (12%) and 10 (6%) of patients subjected to open or laparoscopic surgery, respectively (p < 0.05). Four patients operated using a laparoscopic approach had to be converted to open surgery. Two patients operated using an open approach had a postoperative leak. One patient had an abscess and one a hemoperitoneum. Conclusions: The surgical approach of choice for achalasia is laparoscopic, with a low incidence of complications
