NCT ID: NCT06097650 Recruiting - Haemorrhage Clinical Trials

Cold Snare Polypectomy Versus Hot Snare Polypectomy for Resection of Small Pedunculated Colorectal Polyps:a Randomized Controlled Trial

Start date: October 18, 2023
Phase: N/A
Study type: Interventional

Endoscopic resection of pedicled polyps mainly focuses on how to prevent bleeding, and also needs to pay attention to the convenience of resection and the integrity of resection, which means that different endoscopic resection strategies should be adopted for pedicled polyps with different pedicle sizes. Small pedicled polyps with heads smaller than 20mm and pedicles smaller than 5mm are defined as having a relatively small risk of bleeding. Preliminary studies in recent years suggest that the use of cold snare polypectomy for small pedicled polyps may also be a safe resection strategy. However, for small pedicled polyps, ASGE and ESGE guidelines currently recommend hot snare polypectomy in the middle and lower pedicles (evidence level medium). Therefore, the provision of high-quality clinical evidence related to cold resection techniques in the resection strategy of small pedicled polyps may provide a basis for revision of guidelines.

NCT ID: NCT06097637 Recruiting - Haemorrhage Clinical Trials

Underwater Endoscopic Mucosal Resection Versus Metal Clips With Hot Snare Polypectomy for Resection of Big Pedunculated Colorectal Polyps:a Randomized Controlled Trial

Start date: October 19, 2023
Phase: N/A
Study type: Interventional

Endoscopic resection of pedicled polyps mainly focuses on how to prevent bleeding, and also needs to pay attention to the convenience of resection and the integrity of resection, which means that different endoscopic resection strategies should be adopted for pedicled polyps with different pedicle sizes. The head larger than 20mm or pedicle larger than 5mm are defined as large pedicle polyps, which are at greater risk of bleeding. Current guidelines recommend hot removal by snare following preoperative saline injection, ligation of the pedicle with a nylon ring or metal clip, depending on the size of the polyp head and pedicle. However, the use of snares and metal clamps does not appear to reduce delayed postoperative bleeding, and the technical requirements of nylon ligation are relatively high. Recent studies have found that Underwater endoscopic mucosal resection (UEMR) is also safe and effective for the treatment of large and medium colorectal stemless polyps. Therefore, it is still necessary to further explore new safe and effective endoscopic resection strategies and techniques.

NCT ID: NCT01879475 Recruiting - Clinical trials for C.Surgical Procedure; Cardiac

Safety and Performance of 032-11 Haemostat in Cardiac and Thoracic Aortic Surgery

Start date: June 2013
Phase: N/A
Study type: Interventional

The effectiveness objective of this study is to evaluate whether 032-11 is non-inferior to Floseal as an adjunct to achieving haemostasis during surgical procedures involving cardiac and aortic thoracic surgery.
