Abstract

Pseudoachalasia accounts for up to 4% of patients who present with achalasia-like picture and most often relates to occult malignancy at the cardia or gastroesophageal junction. Thus, any delay in diagnosis might lead to more advanced disease and less chance for curative therapy, not to mention the risk of serious complications resulting from the treatment of supposed achalasia instead of the true underlying cause. The entity should be suspected in patients with advanced age of onset, a shorter duration of symptoms, profound weight loss and difficulty in passing the gastroesophageal junction on endoscopy. The diagnosis of pseudoachalasia can be challenging as upper endoscopy with biopsy might be false negative in 25% of cases and lesions cannot always be detected on computerized tomography scan. Endoscopic ultrasound and guided biopsy play an increasingly important role in the workup of this condition. Treatment of pseudoachalasia depends on the underlying cause. The aim of this review is to highlight the clinicopathological features that distinguish pseudoachalasia from achalasia and the most appropriate diagnostic workup as well as the subsequent management for this condition.
