Abstract
Gastroesophageal reflux disease (GERD) after peroral endoscopic myotomy (POEM) has been a limiting factor with POEM. Sling-fiber preservation during POEM was reported to reduce postoperative GERD in Japan. This study investigates the efficacy of this technique in a western population. This is a retrospective, single-center study of patients undergoing POEM from October 2017 to January 2023. The initial cohort of patients were treated by conventional POEM, after which a second cohort underwent POEM with sling-fiber preservation. The primary outcome was the incidence of postoperative reflux symptoms. The secondary outcomes were clinical success rate (Eckardt score ≤ 3), procedure time, and adverse events rate. Multivariate regression was then performed to identify factors associated with the incidence of postoperative reflux symptoms. One hundred and forty eight POEM cases (52.5 ± 15.6 y/o, female: 61[43%]) were included. The mean procedure time (108.6 ± 34.5 vs. 109.1 ± 45.7 min, P = 0.93) was similar between the groups. In the sling-fiber preservation group, gastric myotomy length was significantly longer (2.2 ± 0.7 vs. 1.6 ± 0.8 cm, P < 0.05), yet the incidence rate of postoperative reflux symptoms at follow-up was significantly lower (22.4% vs. 42.3%, P < 0.05). The clinical success rate was similar between groups (89.5% vs. 83.1%, P = 0.32), and the rate of adverse events requiring intervention (13.5% vs. 12.2%, P = 0.36) was similar. Regression analysis indicated that, after adjusting for other risk factors of postoperative GERD, sling-fiber preservation during POEM had an odds ratio of 0.24 (95% CI: 0.07-0.85, P < 0.05) for the incidence of reflux symptoms. Sling-fiber preservation during POEM reduces the incidence of postoperative reflux symptoms. As such, sling-fiber preservation may be a useful solution to reduce post-POEM GERD in western populations.
