All cold resections were limited to the shallow submucosa, while 60% of hot resections advanced to the deep submucosa and 20% to the muscularis propria (p<0.001). There was no significant difference in the width of destruction. In hot resections, the number of remaining large vessels had a trend toward fewer (p=0.15) and the depth of remaining submucosa was less (p=0.007). In deep submucosa, the vessel diameter was larger (p<0.001) and the number of large vessels was greater (p=0.018).

Patients scheduled to undergo colorectal resection
On the day before surgery, 2 mucosal resections (hot and cold) of normal mucosa were performed on each patient using the same snare without saline injection. The difference was only the application of electrocautery or not. Resection sites were placed close to the cancer to be included in the surgical specimen.
None
The primary outcome measure was the depth of destruction. Secondary outcome measures included the width of destruction, depth of the remaining submucosa, and number of vessels remaining at the resection sites. The number and diameter of vessels in undamaged submucosa were also evaluated.
