A Comparison of Endoscopic Synchronous Injection and Submucosal Dissection(ESISD) and Conventional Endoscopic Submucosal Dissection(CESD) for Granular Mixed Nodular Laterally Spreading Tumor in the Rectum (LST-G-M)
Sponsor: Taihe Hospital
Summary
What is the study about? This study introduces and evaluates a new endoscopic technique called Endoscopic Synchronized Injection and Submucosal Dissection (ESISD). It is designed to remove large, flat precancerous growths in the rectum, known as Granular Mixed Nodular Laterally Spreading Tumors (LST-G-M). We compared this new technique to the standard procedure, Conventional Endoscopic Submucosal Dissection (ESD), to see if it is safer, faster, and more efficient. Who is this for? This research is intended for patients with large, flat rectal polyps, their families seeking the latest treatment options, and healthcare providers interested in advancements in minimally invasive gastroenterology procedures.

Endoscopic Synchronous Injection and Submucosal Dissection(ESISD)
ESISD eliminates the need for injection needles or specialized submucosal agents by integrating injection and dissection into a single procedure. This approach reduces procedural costs, shortens the operation time, and enhances hemostasis during dissection. Additionally, it minimizes electrosurgical carbonization of the knife, preserving its cutting efficacy. The simplicity and broad applicability of ESISD can enhance traditional ESD workflows, warranting further validation across diverse patient populations.
Conventional Endoscopic Submucosal Dissection(ESD)
ESD provides a minimally invasive approach for curative treatment of benign, precancerous, and early neoplastic lesions in the gastrointestinal tract
