Esophageal Motor Disorders Essential Tremor 559
■Pneumatic dilation under fluoroscopic control improves dysphagia,
regurgitation and chest pain in the majority of cases but carries the
risk for perforation
■Laparoscopic myotomy with or without concomitant partial fundo-
plication is increasingly used because of its high efficacy and low
morbidity
follow-up
During Treatment
■Efficacy of therapy needs to be objectively assessed because of the
intermittent nature of the symptoms
Routine
■Endoscopic surveillance for cancer in patients with achalasia is not
cost-effective and thus not recommended
complications and prognosis
■Patients with achalasia are at an increased risk for developing squa-
mous esophageal cancer
■Generally good prognosis for patients with esophageal motor disor-
ders and most patients manage with medical therapy alone
■In patients with achalasia, botulinum toxin injection provides symp-
tom relief but needs to be repeated
■Both pneumatic dilation and surgery, if successful initially, have
long-lasting results
