BACKGROUND: After achalasia treatment, a subset of patients has poor esophageal emptying without having symptoms. There is no consensus on whether to pre-emptively treat these patients. We hypothesized that, if left untreated, these patients will experience earlier symptom recurrence than patients without stasis.
METHODS: 99 treated achalasia patients who were in clinical remission (Eckardt ≤3) at 3 months after treatment were divided into two groups, based on presence or absence of esophageal stasis on a timed barium esophagogram performed after 3 months.
KEY RESULTS: Two years after initial treatment, patients with stasis after treatment still had a wider esophagus (3 cm; IQR: 2.2-3.8) and more stasis (3.5 cm; IQR: 1.9-5.6) than patients without stasis (1.8 cm wide and 0 cm stasis; both P<.001). In patients with stasis, the esophageal diameter had increased from 2.5 to 3.0 cm within 2 years of follow-up. The symptoms, need for and time to retreatment were comparable between the two groups. Quality of life and reflux symptoms were also comparable between the two groups.
CONCLUSIONS & INFERENCES: Although patients with stasis initially had a wider esophagus and 2 years after treatment also had a higher degree of stasis and a more dilated esophagus, compared to patients without stasis, they did not have a higher chance of requiring retreatment. We conclude that stasis in symptom-free achalasia patients after treatment does not predict treatment failure within 2 years and can therefore not serve as a sole reason for retreatment.
