Mechanical Modalities of Endoscopic Therapy: Clips, Loops, and Beyond

Mechanical methods of endoscopic hemostasis are rapidly gaining acceptance due to their efficacy and safety. Nonetheless, some problems still exist as to their general applicability since both clipping and banding are technically demanding procedures which depend on the operator's expertise and team trained approach. Improvements in clip design and materials, together with progress in the loading and release systems will hopefully lead to the more widespread use of such mechanical methods with the aim of preventing recurrent bleeding. Elastic band ligation is a relatively simple procedure whose application in the management of nonvariceal bleeding has recently expanded to include selected patients with peptic ulcer bleeding.
