Botulinum toxin injected into the narrow lower segment (LES) is a recognised, safe outpatient treatment for achalasia with results similar to balloon dilatation. Why the others are wrong:
- A: manometry shows failure of LES relaxation with aperistalsis of the esophagus, not a problem confined to the upper esophagus.
- B: the parasitic cause (Trypanosoma cruzi, Chagas disease) occurs in South America, not North America.
- D: achalasia raises cancer risk, but the sources give no 20% figure.
