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

Table 3

Comparisons between conventional ESD and ESD with TTSPS.

Conventional ESDESD with TTSPS p value

Median dissection time (min) (range)90 (30–320) 60 (15–160)0.015
Median number of incidences of arterial bleeding (range)3 (0–25)2 (0–7)0.015
Median number of local injections (range)10 (3–51) 8 (1–27)0.04

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