OBJECTIVE: Report the long-term subjective and objective results of esophageal myotomy and fundoplication by thoracotomy in treating esophageal spastic disorders.
METHODS: From 1977 to 1995, 16 patients with esophageal spastic disorders underwent a myotomy with an added partial (12) or total (4) fundoplication. The median follow-up is 6 years. Assessments include clinical evaluation, esophagogram, radionuclide emptying, manometry, 24-hour pH, and endoscopy. From global results, patients with pure spastic disorders (8) were compared to patients with spastic disorders and an epiphrenic diverticulum (8).
RESULTS: There is no mortality and minimal morbidity. Results are summarized in table 1. Failure (Persistant symptoms, reflux damage or obstruction to emptying) was observed in 1 patient with a diverticulum at 9 years and in 4 patients with pure spastic disorder at 2, 3, 6, and 8 years after the operation (Log-rank test, p=0.029).
CONCLUSIONS: Long myotomy and fundoplication for spastic disorders: Reduces dysphagia and chest pain; Reduces distal peak contraction pressures and peristalsis; Decreases LES pressures. Improves LES relaxation. Spastic disorder patients with a diverticulum, when compared to pure spastic disorder patients, show better clinical results, better esophageal function.
