A 2-microm continuous-wave laser system for safe and high-precision dissection during NOTES procedures.

Introduction: Lasers 2-microm in wavelength offer efficient tissue cutting with limited thermal damage in biological tissue.

Objective: To evaluate the dissection capabilities of a 2-microm continuous-wave laser for NOTES procedures.

Methods And Procedures: We conducted 18 acute animal experiments.

Gastric wall healing after NOTES procedures: closure with endoscopic clips provides superior histological outcome compared with threaded tags closure.

Background: Closure of the transgastric access to the peritoneal cavity is a critical step in natural orifice transluminal endoscopic surgery (NOTES).

Objective: To perform a direct comparison of the histological healing post clips and threaded tags (T-tags) closure after transgastric NOTES procedures.

Design And Intervention: Twelve survival porcine experiments.

Hydrogen leak test is minimally invasive and highly specific for assessment of the integrity of the luminal closure after natural orifice transluminal endoscopic surgery procedures (with video).

Background: Leak-resistant closure of transluminal access is a major challenge facing natural orifice transluminal endoscopic surgery (NOTES).

Objective: To evaluate a hydrogen (H(2))-based leak test for assessment of transluminal-access closure integrity after NOTES procedures.

Setting: Nine acute porcine experiments.
