Summary
A new grasping scissors forceps (GSF) improves endoscopic submucosal dissection (ESD) safety. This innovative tool reduces complications like perforation and bleeding during gastrointestinal tumor resection.
Area of Science:
- Gastroenterology
- Surgical Innovation
- Endoscopic Procedures
Background:
- Endoscopic submucosal dissection (ESD) using traditional knives presents technical challenges.
- High complication rates, including perforation and bleeding, are associated with conventional ESD techniques.
- Limitations include poor tissue fixation and lesion compression during knife-based dissection.
Observation:
- A novel grasping type scissors forceps (GSF) was developed to enhance ESD.
- Colonoscopy identified a 10-mm rectal submucosal carcinoid tumor in a 55-year-old woman.
- Endoscopic ultrasonography confirmed a submucosal tumor without lymph node metastasis.
Findings:
- The GSF enabled safe and accurate resection of the rectal carcinoid tumor via ESD.
- The procedure using GSF resulted in no unexpected incisions.
- No delayed hemorrhage or perforation complications were observed post-procedure.
Implications:
- The GSF shows potential to minimize complications in endoscopic submucosal dissection.
- This tool may offer a safer alternative for resecting gastrointestinal submucosal lesions.
- Successful GSF application in carcinoid tumor resection suggests broader applicability in GI oncology.
