title: A rare case of achalasia coexistent with sigmoid megacolon and associated with epilepsy.
abstract: A case of achalasia coexistent with sigmoid megacolon in a 38-year-old man with known epilepsy is described. The patient was referred to the Ryukyu University Hospital with a 4-year history of dysphagia and heartburn and a 1-year history of abnormal bowel movement. On admission, upper gastrointestinal (GI) series demonstrated a dilated, tortuous thoracic esophagus with a flask-type configuration. Barium enema studies showed a dilated sigmoid colon from the rectosigmoid junction to the descending colon. Myotomy (modified Jekler-Lhotka's procedure) for achalasia and simple sigmoidectomy for sigmoid megacolon were carried out. The biopsied wall of the narrowed esophageal segment at operation showed decreased numbers of ganglion cells in Auerbach's plexus and atrophy of the muscle fibers. The resected dilated sigmoid colon revealed degeneration and markedly decreased numbers of ganglion cells in Auerbach's and Meissner's plexuses. The patient's postoperative course was uneventful and he has been doing well since surgery. The present case is very interesting and to our knowledge, such a case is rare in the literature. We believe that the abnormalities of the ganglion cells may be due to the same etiologic factor as the sigmoid megacolon. The association of the two pathologic processes is discussed, together with a brief review of the literature.
