Background: new alternatives for entry site closure (ESC) in per-oral endoscopy myotomy (POEM) and gastric peroral endoscopy myotomy (G-POEM) have appeared. Objective: to compare the over-the-scope-clip (OTSC®) and conventional clips (CC) for ESC in POEM and G-POEM. Material and methods: a retrospective review of a prospective POEM and G-POEM database was performed between January 2015 and August 2019. A description was made of outcomes, using either OTSC® or CC for submucosal tunnel closure. Results: forty-six POEM and 26 G-POEM were included in the study (23/13 per group [CC/OTSC®]). There were no clinical or procedure differences. ESC was performed with 1 OTSC® vs 5 CC and 1 vs 6 (p = 0.01) for POEM and G-POEM, respectively. Adverse events associated with clips were 21.7% vs 13% (p = 0.01) and 7.7% vs 0% (p = 0.02) for CC and OTSC® in POEM and G-POEM, respectively. Conclusion: OTSC® represents a safe and effective alternative for entry site closure in POEM and G-POEM cases. Further studies are needed to recommend OTSC® as the first option for submucosal tunnel closure in these procedures.
