Endoscopic resection of colitis-associated neoplasia: A scoping review

Table 7 Lifting and traction techniques in endoscopic submucosal dissection for ulcerative colitis associated neoplasias

Technique	Key feature	Application context	Advantage
PuraLift[39]	Self-assembling peptide lifting agent	All GI segments, excluded fibrosis cases	Low injection resistance, sustained lift
Multitraction[40]	3-looped clip system for recurrent lesion	UC recurrence with fibrosis	Enables re-entry and dissection in fibrotic bed
Triangulated “Wallet”[41]	Rubber band traction with 3-point clip fixation	Fibrotic rectal lesions in UC	Strong, adaptive perpendicular traction
Double-tunneling[42]	Bilateral flaps with preserved septum (“butterfly”)	Extensive rectal LSTs in UC	Maintains orientation, avoids flap rolling
PCM[43]	Submucosal pocket dissection under fibrosis	Residual dysplasia post-EMR + inflammation	Isolates fibrotic layer; good for UC mucosa

UC: Ulcerative colitis; EMR: Endoscopic mucosal resection; GI: Gastrointestinal; LSTs: Laterally spreading tumors; PCM: Pocket creation method.
