Pre- and postoperative manometric studies in diffuse esophageal spasm.

F París, A Benages, J Berenguer

    The Journal of Thoracic and Cardiovascular Surgery

    Summary

    Extramucosal myotomy effectively relieved symptoms of idiopathic diffuse esophageal spasm in four patients. While not curing the functional disorder, this surgical intervention reduced esophageal wave pressures and eased dysphagia and chest pain.

    Area of Science:

    • Gastroenterology
    • Surgical Innovation
    • Esophageal Motility Disorders

    Background:

    • Idiopathic diffuse esophageal spasm (IDES) presents significant challenges in symptom management.
    • Surgical interventions for esophageal motility disorders require careful evaluation of efficacy and impact on esophageal function.

    Purpose of the Study:

    • To assess the effectiveness of extramucosal myotomy in treating idiopathic diffuse esophageal spasm.
    • To evaluate the impact of myotomy on esophageal manometric parameters and clinical symptoms.

    Main Methods:

    • Four patients with IDES underwent extramucosal myotomy from the gastric fundus to the aortic arch.
    • Pre- and postoperative clinical evaluations, barium studies, and esophageal manometry were performed.

    Main Results:

    • All patients experienced resolution of dysphagia and substernal pain post-surgery.
    • Radiological patterns improved in three patients.
    • Myotomy significantly reduced esophageal body contractile wave pressures and, in some cases, basal pressures.
    • Lower esophageal sphincter function showed altered relaxation and contraction patterns post-myotomy.

    Conclusions:

    • Extramucosal myotomy provides symptomatic relief for IDES by reducing esophageal wave amplitude and elevated resting pressures.
    • While myotomy does not alter the underlying functional disorder, it effectively manages patient symptoms.
