Functional outcome after Heller myotomy and fundoplication for achalasia.
This study aims to provide longitudinal prospective data on symptomatic outcome following Heller myotomy with fundoplication and to examine variables that might predict a poor outcome. Patients were prospectively followed by means of a biannual mailed questionnaire that assessed symptoms, satisfaction with the procedure, medication, and need for further intervention. Patients were classified as achieving a good or poor outcome based on predetermined criteria. Duration of clinical remission was determined using Kaplan-Meier curves. Between 1992 and 1999, 62 patients with at least 12 months' follow-up were categorized as having either a good outcome (41 patients) or a poor outcome (21 patients). The cumulative probability of a good outcome at 7 years was 37%. Dysphagia significantly increased over the follow-up period despite initial resolution. Patient variables (age, sex, symptom duration, esophageal dilatation, manometric findings) and operative factors (myotomy length, wrap type, case number mucosal perforation, primary therapy) were not demonstrated to influence outcome at 3 years. A comparison of Nissen fundoplication with partial fundoplication suggested increased dysphagia and chest pain in the Nissen group. Despite initial symptomatic relief, patients with achalasia suffer a progressive decline with recurrent dysphagia and regurgitation. The type of fundoplication used may contribute to these poor results.
