Herniation of the Esophageal Mucosa After Epiphrenic Diverticulectomy

The patient is a 62-year-old male, diagnosed with a giant epiphrenic diverticulum and diffuse esophageal spasms, who underwent laparoscopic and thoracoscopic diverticulectomy, cardiomyotomy and anti-reflux surgery. The myotomy was more extensive than usual due to the hyper pressure of the entire lower third of the esophagus (corkscrew esophagus). The patient's condition progressed favorably. Nine years later, he presented occasional symptoms of dysphagia. A barium swallow study revealed saccular dilatation compatible with herniation of the mucosa through the region of the myotomy (Fig. 1).
