Optimizing Endoscopic Submucosal Dissection: A Meta-Analysis of the S-O Clip's Impact on Procedural Outcomes and Lesion-Specific Applications.

Background: Endoscopic submucosal dissection (ESD) is a minimally invasive procedure used to treat early-stage gastrointestinal neoplasms. While effective, ESD can be technically challenging due to limited submucosal visibility, prolonged procedure time, and increased risk of adverse events such as perforation and bleeding. The S-O clip, a traction device designed to enhance submucosal exposure, may help overcome these limitations and improve procedural outcomes.

Low-repetition rate femtosecond laser writing of optical waveguides in KTP crystals: analysis of anisotropic refractive index changes.

We report on the direct low-repetition rate femtosecond pulse laser microfabrication of optical waveguides in KTP crystals and the characterization of refractive index changes after the thermal annealing of the sample, with the focus on studying the potential for direct laser fabricating Mach-Zehnder optical modulators. We have fabricated square cladding waveguides by means of stacking damage tracks, and found that the refractive index decrease is large for vertically polarized light (c-axis; TM polarized) but rather weak for horizontally polarized light (a-axis; TE polarized), this leading to good near-infrared light confinement for TM modes but poor for TE modes. However, after performing a sample thermal annealing we have found that the thermal process enables a refractive index increment of around 1.
