Clinical presentation and evaluation of malignant pseudoachalasia.
Malignant pseudoachalasia can be indistinguishable from primary achalasia on routine clinical evaluation, often resulting in a delay in diagnosis. To better define the clinical features and appropriate management of this disease, the course of five patients discovered to have pseudoachalasia after being referred for a minimally invasive Heller myotomy was reviewed, as were 67 cases of pseudoachalasia previously reported in the literature. Patients with an occult malignancy tended to present with shorter durations of symptoms, greater weight loss, and at a more advanced age than patients with primary achalasia. Since contrast radiography and endoscopy frequently failed to differentiate these two diseases, persons with presumed achalasia meeting these criteria who are referred for minimally invasive surgery should undergo additional imaging to rule out an occult malignancy, since this condition cannot be reliably detected during the course of a thoracoscopic or laparoscopic esophagomyotomy.
