title: Unusual upper gastrointestinal diseases associated with achalasia: laparoscopic approach.
abstract: BACKGROUND
  As a result of the high success rate associated with the laparoscopic approach for achalasia, surgery for the disease has become the treatment of choice in recent years. With the greater number of patients undergoing surgery, surgeons may encounter other upper gastroesophageal illnesses associated with achalasia, and these may require evaluation for simultaneous surgical treatment. This study aimed to evaluate the incidence of gastroesophageal diseases associated with achalasia, and to determine the possibility for simultaneous management using the laparoscopic approach.
  
  
  METHODS
  From January 1999 to May 2006, 81 patients were referred from the Service of Gastroenterology to the Service of General and Digestive Surgery as candidates for the surgical management of achalasia. Data for this group were recorded prospectively in laparoscopic surgery databases at the Hospital Sant Pau and the Hospital de Igualada. A total of 78 patients underwent laparoscopic Heller myotomy with gastric fundoplication.
  
  
  RESULTS
  In 8 of 81 patients, nine additional gastroesophageal diseases (11.1%) were found: three cases of pseudoachalasia (3.7%), three cases of paraesophageal hiatal hernia (3.7%), two cases of esophageal diverticulum (2.5%), and one case of gastric volvulus (1.2%). Pseudoachalasia was diagnosed for three patients. The diagnosis was made preoperatively for one of these patients. For the other two patients, an adenocarcinoma arising from the gastroesophageal junction was diagnosed during the laparoscopy. In three cases, a paraesophageal hiatal hernia was found and treated by laparoscopic Heller myotomy, sac excision, hiatal closure, and posterior fundoplication. Esophageal diverticulectomy was performed for one patient. Another patient presented with an organoaxial gastric volvulus associated with achalasia, for which laparoscopic Heller myotomy, posterior fundoplication, and anterior gastropexy were performed. The median follow-up period was 39 months, with no recurrence.
  
  
  CONCLUSIONS
  Despite their infrequency, several gastroesophageal diseases may be found in association with achalasia. Laparoscopic surgery may be useful for the diagnosis and/or treatment of both diseases.
