What is one benefit of mucosal resection with submucosal saline injection?

Mucosal resection with submucosal saline injection provides significant benefits, particularly in elevating lesions and creating a thermal buffer. When saline is injected into the submucosal layer, it lifts the lesion away from the underlying structures. This elevation is crucial because it allows for a clearer resection margin during the procedure, facilitating complete removal of the lesion with minimal thermal injury to adjacent tissues. The thermal buffer created by the saline helps to protect the deeper layers from heat damage during cauterization, thereby reducing the potential for complications such as perforation or postoperative strictures. This technique enhances the safety and effectiveness of the procedure, making it a preferred approach in endoscopic surgeries.
