Achalasia of the Esophagus

During a 15-year period, 62 patients were treated for achalasia of the esophagus. Pneumatic dilation (PD) had been performed initially in 46 and was successful in 23; failures were due to acute perforation of the esophagus, persistent dysphagia, or pathologic gastroesophageal reflux. Esophagomyotomy alone (EM) was performed in 19 individuals resulting in definite improvement in 12; four patients had moderate reflux or dysphagia, and three of these required another surgical procedure. An extended myotomy with an antireflux procedure (M-NF) was performed in 13 patients with symptomatic relief in 12; one patient required reconstruction of a too-tight fundoplication that caused persistent dysphagia. The advantages of pneumatic dilation were the ease of performance, patient acceptability, and an overall efficacy of 50%. Definitive surgical therapy, while more predictably effective in relieving dysphagia, was considerably more expensive in terms of patient discomfort and time. When pathologic reflux was present following a previous procedure, the M-NF was performed; obstruction of the esophagus did not occur if the fundoplication was "floppy." The M-NF deserves consideration as the surgical procedure of choice for achalasia.
