Utility of under-gel endoscopic mucosal resection with partial submucosal injection and under-gel precutting endoscopic mucosal resection for difficult colorectal polyp cases

Conclusions: PI is potentially useful for colorectal polyps where the distal end is not visible; when PI cannot be used, pre-cutting EMR may constitute another troubleshooting method for difficult-to-treat colorectal polyps. The gel immersion method is also a viable option when the use of water causes rapid mixing of blood and residual stool, resulting in poor visibility.
