Thread-Traction with a Sheath of Polypectomy Snare Facilitates Endoscopic Submucosal Dissection of Early Gastric Cancers

Table 4

Comparisons of complications between conventional ESD and ESD with TTSPS.

	Conventional ESD	ESD with TTSPS	p value
Post-ESD bleeding (%); (present : absent)	3 : 31 (8.8%)	1 : 53 (1.9%)	NS
Perforation (%); (present : absent)	2 : 32 (5.9%)	1 : 53 (1.9%)	NS

ESD: endoscopic submucosal dissection; NS: not significant; and TTSPS: thread-traction method using a sheath of polypectomy snare.
