Abstract
Objectives: To study the pretreatment characteristics that predispose a patient to rupture and to compare the outcome after dilatation with the outcome after surgical myotomy. Design: A survey of all patients treated for achalasia at the Creighton University Medical Center, Omaha, Neb, during a 16-year period. Clinical examination and testing of consenting patients at 12 months and longer after treatment. Setting: Tertiary referral center. Patients: Of the 61 patients, 55 were treated with dilatation. Esophageal rupture developed in 8 patients (14.5%) with achalasia after pneumatic dilataion; these patients underwent surgery for the rupture. Dilatation failed in 8 other patients; these patients underwent a surgical myotomy. Six patients underwent a primary surgical myotomy. Main Outcome Measures: Duration of symptoms, weigth loss, lower esophageal sphincter resting pressure and relaxation, amplitude and quality of distal esophageal contractions (assessed by manometry), 24-hour esophageal pH, and maximal esophageal diameter (assessed by barium swallow examination). Results: Surgical myotomy at a mean (±SEM) of 44.9±18.6 months alleviated dysphagia in 13 (93%) of the 14 patients compared with only 12 (39%) of the 31 patients after dilation at a mean (±SEM) of 55.0±11.7 months (P
