Materials And Methods:
This was a retrospective cohort study conducted in two municipal hospitals. We identified 24 patients with SNADETs of 3-18 mm in diameter who underwent UEMR or GIEMR. One lesion was excluded from the analysis because it was found to be in the stomach after surgery. The primary outcome was procedure time.
Results:
GIEMR significantly reduced the procedure time compared with UEMR (5 min vs. 10 min, P = 0.016). There was no significant difference between the UEMR and GIEMR groups for en bloc resection rate (93% vs. 100%, P = 1.0) and R0 resection rate (57% vs. 80%, P = 0.39). No serious complications were observed in either group.
Conclusions:
GIEMR of SNADET has the potential to reduce procedure time compared with UEMR and may be particularly effective in areas where immersion in water is difficult.
