Description
Summary:Abstract Background Per-oral endoscopic myotomy (POEM) for esophageal achalasia has increasingly become a mainstream procedure worldwide, and its short and middle term efficacy and safety are more and more recognized. However, the long-term outcomes are still unclear and we sometimes experience the cases with severe post-operative GERD and residual chest pain. Methods We retrospectively reviewed 241 cases who were performed POEM in our center from Apr 2015 to Feb 2022 and evaluate their post-operative GERD and residual chest pain. Results Before POEM, 126 cases (54.8%) had chest pain. Residual chest pain 2 months after POEM was observed in 28 patients (23.1%). 78.2% had complete remission of chest pain after 1 year. Severe GERD (LA Grade C or D) 2 months and 1 year after POEM was observed in 5.1%, 8.2%, respectively. All of them except one patient were improved by PPIs. On univariable analysis, younger patients and pre-treatment were at risk for residual chest pain (p=0.02, p=0.04, respectively). Higher BMI was risk for severe GERD after 2 months (p=0.02), however it was not associate with that after 1 year (p=0.04). Conclusion Younger age and pre-treatment were at risk for residual chest pain after POEM and post-operative severe GERD was related to higher BMI, however almost all of them was controlled by PPIs. The number of cases was small, so it is necessary to accumulate more cases.
