Endoscopic submucosal dissection (ESD) using new grasping scissors forceps (GSF) offers a safer alternative to traditional knives. This innovative tool reduces complications by precisely grasping and incising tissue during gastrointestinal neoplasm resection.

Area of Science:

  • Gastroenterology
  • Surgical Innovation
  • Endoscopic Procedures

Background:

  • Endoscopic submucosal dissection (ESD) using knives is technically challenging.
  • Current methods have a high complication rate due to difficulty in fixing the knife to the target lesion, leading to perforation and bleeding.

Purpose of the Study:

  • To develop and evaluate a novel grasping type scissors forceps (GSF) for ESD.
  • To reduce complications associated with traditional ESD techniques.

Main Methods:

  • The GSF was developed to grasp and incise tissue using electrosurgical current.
  • ESD procedures were performed using the GSF on resected porcine stomachs in vitro.
  • The technique involved marking lesions, submucosal injection, and complete incision around the lesion using GSF.

Use of the Scissor-Type Knife During the Peroral Endoscopy Myotomy Procedure for the Treatment of Achalasia

Published on: March 3, 2023

Main Results:

  • ESD using the GSF was performed safely and easily in an in vitro animal model.
  • Unintentional incisions were avoided, indicating improved precision.
  • Submucosal exfoliation was achieved by grasping and cutting tissue with the GSF.

Conclusions:

  • ESD using GSF is a safe, easy, and technically efficient method.
  • GSF may reduce the risk of major complications during gastrointestinal neoplasm resection.
