Methods A retrospective chart review of consecutive patients was performed to identify
individuals with achalasia who underwent hydraulic dilation using the EsoFLIP system
between January 2018 and September 2019 at a tertiary care center. The primary outcome
was procedure related complications and secondary outcome was clinical efficacy, defined
as an Eckardt score≤ 3. Patients were contacted at minimum one-month post procedure to
determine their post-procedure Eckardt score.
