Background/aims: There have been several reports of thermal injury induced by argon plasma coagulation (APC) in animal models, but no follow-up studies have revealed the actual thermal injury.
Methods: APC was performed on the stomachs of two living minipigs with and without prior submucosal injection of normal saline. The power and argon gas flow were set to 60 watts and 2 L/min, respectively, and pulse durations of 5, 10, and 20 seconds were used.
Tissue damage of different submucosal injection solutions for EMR.

Article Synopsis
- The study examined the tissue damage potential of various submucosal injection solutions used in endoscopic mucosal resection (EMR).
- Solutions tested included normal saline, different concentrations of dextrose water, glycerin, and hyaluronic acid, with injections performed on living minipigs and evaluations conducted after 30 minutes or one week.
- Findings suggest that hypertonic solutions (except glycerin) can cause significant tissue damage, while the combination of hyaluronic acid and glycerin is recommended for minimizing damage and maximizing lesion-lifting ability.
