Procedures
Haemoclip Application In GI Bleed
- Haemoclips are mechanical devices used to approximate two sides of a vessel to immediately, definitively, and securely occlude and arrest bleeding. On opening, the haemoclip is typically 11–12 mm wide from jaw to jaw.
- Haemoclips are best deployed enface rather than tangentially. Haemoclip need to be placed at the correct angle and precise spot. Missing a target, even slightly, can render a haemoclip ineffective
- At least two haemoclips are generally placed to clamp an actively bleeding artery in an ulcer. Haemoclips are relatively inefficacious for arteries that are larger than 2 mm wide. Haemoclips generally fall off 10–14 days after deployment—after the lesion has partly healed and when the lesion is unlikely to rebleed
- The placement of these clips rarely produces complications other than failed efficacy. Haemoclips are less successful for the treatment of fibrotic lesions such as chronic ulcers
- Hemoclips and thermocoagulation or electrocoagulations are equally efficacious in achieving long term haemostasis.
Patient preparation for the procedure
Preparation for haemocliping is fasting for 4-6 hours similar to performing a regular esophagogastroduodenoscopy (EGD). An intravenous line is placed to deliver sedation or other medications.
