The physiologic abnormalities and management of patients with diffuse
esophageal spasm are controversial. We evaluated the symptomatic and
functional results of surgical therapy in 19 patients with diffuse
esophageal spasm who were incapacitated with dysphagia and chest pain and
unresponsive to conservative management. A long esophageal myotomy with an
antireflux procedure was performed in 15 patients, and four patients with
multiple previous esophageal procedures had an esophagectomy. Eleven
patients had increased esophageal exposure to gastric juice on preoperative
24-hour esophageal pH monitoring. The severity of dysphagia, chest pain,
regurgitation, and heartburn was scored on a scale of 0 to 3 before and a
mean of 24 months (range 8 months to 13 years) after the operation. After
myotomy, each of these symptoms and the overall symptom score improved
significantly (p < 0.01). The improvement in the symptom scores in the
patients who had esophagectomy were comparable with the improvement after
myotomy. On self-assessment, 90% of the patients would have the operation
again if again faced with the decision. Standard and ambulatory 24-hour
manometry showed a significant reduction in the amplitude of the esophageal
body contractions, a decrease in the frequency of simultaneous
contractions, and the elimination of multi-peaked waves after the myotomy.
Despite the addition of an antireflux procedure, lower esophageal sphincter
pressure, overall length, and abdominal length were reduced markedly after
the myotomy. This was associated with persistent or emerging heartburn or
regurgitation in four patients. These data indicate that a long esophageal
myotomy is a valid treatment alternative in appropriately selected patients
with diffuse esophageal spasm. Esophagectomy and colon interposition is the
procedure of choice in patients with multiple previously failed myotomies.
