Abstract

Background/Aims
Achalasia and hiatal hernia are rarely associated. The aim of the current study is to explore the clinical and manometric findings in patients with achalasia and hiatal hernia, and to determine if the presence of a hiatal hernia should influence therapeutic management in patients with achalasia.
Methods
This retrospective single center analysis included a group of patients with achalasia and hiatal hernia (study group) and a group of matched patients with achalasia but no hiatal hernia (control group). We recorded demographic, clinical, endoscopic, and manometric parameters and compared initial presentation and treatment outcomes between the groups.
Results
Between 2015 and 2022, achalasia was diagnosed in 294/1513 (19.4%) patients. Concomitant hiatal hernia was identified in 13/294 (4.4%) patients. Compared to patients with achalasia and no hiatal hernia, patients in the study group had lower Eckardt scores at baseline (5.4 ± 2.0 vs 7.8 ± 2.4; P = 0.005) but similar integrated relaxation pressure. Following treatment, patients in the study and control group had similar clinical success and prevalence of gastroesophageal reflux symptoms.
Conclusions
Hiatal hernia is rarely associated with achalasia. The presence of a hiatal hernia should not influence treatment decisions in patients with achalasia.
