Achalasia and Epiphrenic Diverticulum

Surgical Symposium Contribution


Esophageal epiphrenic diverticulum (EED) is a pseudodiverticulum of pulsion type located in the distal 10 cm of the esophagus and frequently associated to achalasia. The symptoms and the pathophysiology of achalasia and EED may overlap, leading to the speculation that achalasia may be responsible for the symptoms. Similarly to patients with achalasia without EED, a careful preoperative evaluation is essential in patients with EED. Endoscopy and an esophagram are mandatory in the workup of these patients, while esophageal manometry confirms the associated motility disorder. Treatment is indicated in all patients fit for an operation except those who are asymptomatic with a small EED and no prior history of aspiration. Laparoscopic Heller’s myotomy and partial fundoplication is the most adequate therapy. Diverticulectomy must be added to the procedure in large diverticula. Experience with endoscopic therapy is very limited.
