Официальное название

Safety and Efficacy of the Novel SpydrBlade Flex With Radiofrequency and Microwave Ablation Flexible Bipolar for Colorectal Endoscopic Submucosal Dissection - A Prospective Study

Обзор

This study is an interventional, prospective, single-center study to evaluate the safety and effectiveness of a novel radiofrequency and microwave ablation flexible bipolar (SpydrBlade Flex, CREO Medical, UK) for colorectal ESD in patients with superficial colorectal neoplasia.

Подробное описание

This is a prospective study with the following study Objectives:

1. To evaluate the safety and effectiveness of a novel radiofrequency and microwave ablation flexible bipolar (SpydrBlade Flex, CREO Medical, UK) for colorectal ESD. 2. To assess the impact of the procedure on patient recovery time and postoperative adverse event.

This study is an interventional, prospective, single-center study to evaluate the safety and effectiveness of a novel radiofrequency and microwave ablation flexible bipolar (SpydrBlade Flex, CREO Medical, UK) for colorectal ESD in patients with superficial colorectal neoplasia. Patients will undergo a ESD for superficial colorectal neoplasia. All ESD procedures will be performed by expert endoscopists with at least 50 prior experience of ESD.

Вмешательства

• Устройство Colorectal ESD with SpydrBlade Flex
  The allocated intervention would be performed under sedation or monitored anaesthesia by experienced endoscopists with at least 50 case experience of colon ESD. Colon ESD procedure would be performed as per described in the literature. After submucosal injection of solution to create a cushion, mucosal incision and submucosal dissection would be performed with the SydrBlade Flex. Submucosal plane dissection will be performed using the SpydrBlade Flex (BRF, cutting frequency 400kHz, power settin
