Abstract
Although hiatal hernia is reported with a 40–50% frequency in the general population, its occurrence and potential implications in achalasia are less well known. We reviewed the medical records and radiographic examinations of 120 patients with achalasia to assess the prevalence of hiatal hernia and its importance in evaluation and management of this motility disorder. Hiatal hernia was present in only 10 (8.3%) patients. Age, sex distribution, prevalence of dysphagia and regurgitation, and lower esophageal sphincter pressure measured manometrically were not significantly different in patients having hiatal hernia compared to those without hernia. Most patients (88%) underwent pneumatic dilatation and five esophageal perforations occurred, but all in patients without hiatal hernia. In conclusion, hiatal hernia is uncommon in patients with achalasia for reasons not known. Age, sex, symptoms, and results of esophageal manometry were not significantly different in those with hiatal hernia. Finally, the presence of hiatal hernia is not a contraindication to treatment of achalasia by pneumatic dilatation.
