Three patients with epiphrenic diverticula were reviewed with foci on esophageal dysfuntion and its relation to treatment. All cases were identified by bariurn esophagogram and confirmed by endoscopy. Manoetric studies of esophagus documented as diffuse esophageal spasm-like disorder in 1 case, and nonspecific motor disorder in 2 cases. One case was managed surgically, and the other 2 were treated conservatively. We found that epiphrenic diverticulum were associated with esophageal motility disorders. Treatment should be considered to focus on associated motility disorders as well as a diverticulum. (Korean J Gastroenterol 1997;29:687-693)
