Among 7,054 patients who underwent primary sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB), 17 patients also underwent procedures for achalasia and EMDs were included. Patients were categorized by treatment sequence: achalasia treatment first (AF), bariatric surgery first (BF), or concurrent treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The cohort had a mean age of 56.9 years and was predominantly female (70.6%).
