A modified snare has been fabricated in prototype form which permits the placement
of a tightenable nylon loop ligature around the stalk of large polyps, which is then
left in situ after withdrawal of the snare handle and endoscope. The clinical application
of the safety snare is likely to be the prevention of immediate or delayed haemorrhage
from the stalks of unusually large polyps, or after polypectomy in patients with bleeding
diathesis. The use of the snare has proved practicable in preliminary clinical trials.
