Overview
The goal of this clinical trial is to investigate whether the flexible auxiliary single-arm transluminal endoscopic robot (FASTER) system can improve the safety of the endoscopic submucosal dissection (ESD). It will also evaluate the efficacy of the system, such as whether it could reduce the procedure time and so on. The main questions it aims to answer are:
Does the use of the FASTER system reduce the number of muscular injuries, improving the safety of the ESD procedure? Does the use of the FASTER system reduce the procedure and dissection time, improving the efficacy of the ESD procedure? Researchers will compare FASTER-assisted ESD and conventional ESD to evaluate the safety and efficacy of the FASTER system.
Participants will:
Be randomly assigned to the group with ESD using the traditional procedure or to the group with ESD assisted by the FASTER system.
Keep a diary of their symptoms after the procedure. ESD has gained widespread acceptance as the standard method for treating early-stage gastrointestinal cancers. Adequate exposure of the submucosa layer through effective tissue traction is vital for the safe and effective performance of ESD. The FASTER system is designed to overcome this technical difficulty.
