1
Radical resection of rectal cancer for resection margin involvement, endoscopic clip hemostasis for postendoscopic mucosal resection bleeding, intestinal perforation repair for perforation.
2
Post-operative bleeding was defined when the following parameters were satisfied: (1) Occurred up to 30 d after transanal minimally invasive surgery/ endoscopic mucosal resection; (2) Hematochezia, melena or dizziness; (3) Required endoscopic hemostasis; and (4) Hemoglobin loss > 2 g/dL. EMR: Endoscopic mucosal resection; TAMIS: Transanal minimally invasive surgery.
