endoclips

Endoclips, also known as endoscopic clips, are small, spring-loaded metallic devices used during endoscopic procedures. They are deployed through the working channel of an endoscope and are primarily employed to close small defects in the gastrointestinal tract. This can include iatrogenic perforations that occur during procedures like endoscopy or polypectomy, as well as bleeding sites that cannot be controlled by other methods.

The design of endoclips varies, but they typically consist of two opposing arms that grasp tissue and then clip together. They are made of biocompatible materials such as stainless steel or titanium. Once deployed, they remain in place, facilitating healing and preventing leakage. They can be used to close a variety of lesions, including small ulcers, diverticula, and post-biopsy defects.

The application of endoclips is a minimally invasive technique that avoids the need for open surgery in many cases. The procedure is performed under sedation or general anesthesia. After visualization of the target site through the endoscope, the endoclip is advanced to the tip of the endoscope, positioned over the defect, and then deployed. The success rate of endoclip closure is generally high for appropriately selected lesions. Complications are rare but can include clip migration or failure to close the defect.
