Peroral endoscopic myotomy for complex achalasia and the POEM difficulty score: An update.

ABSTRACT:

Objectives

We present an update on the (peroral endoscopic myotomy (POEM) difficulty score [PDS] by introducing a novel knife with waterjet functionality.

Methods

This is a retrospective review of patients who underwent POEM between May 2018 and July 2023 at the Kingston Health Sciences Center. Demographic and procedural variables were compared using descriptive and inferential statistics.

Results

One hundred thirty-nine consecutive POEMs were included in the study. Seventy-four (56.7% male; aged 56.7 ± 16.5 years) complex achalasia (CA) and 65 (55.4% female; aged 47.3 ± 20.2 years) non-CA POEM procedures were performed. PDS correlates moderately with procedural efficiency with a correlation coefficient of 0.595 (Spearman's p < 0.001). The mean efficiency for n
