The prevalence of HH in achalasia is significantly lower than in GERD. The longer EL and the higher MELH ratio in achalasia could explain the lower prevalence of HH. Despite the low prevalence of HH in achalasia patients, the surgeon should be encouraged not to rule out HH since the risk of postoperative reflux may increase if this condition is not identified and corrected.
