Endoscopic submucosal dissection for rectal carcinoid tumour using the Clutch Cutter

Area of Science:

• Gastroenterology
• Surgical Oncology
• Endoscopic Surgery

Background:

• Traditional endoscopic submucosal dissection (ESD) using knives carries risks of complications.
• The Clutch Cutter (CC) was developed to grasp and incise tissue using electrosurgical current, mimicking biopsy techniques.
• This innovation aims to improve the safety and efficacy of ESD procedures.

Purpose of the Study:

• To evaluate the efficacy and safety of ESD using the Clutch Cutter (CC).
• To assess the feasibility of CC-assisted ESD for rectal carcinoid tumor removal.

Main Methods:

• Prospective enrollment of seven patients with rectal subepithelial lesions (carcinoid tumors).
• Diagnosis confirmed via endoscopy, endoscopic ultrasound, and biopsies.
• ESD using the Clutch Cutter was performed on all lesions.

Main Results:

• All lesions were resected easily and safely with the CC.
• En bloc resection was achieved in all cases.
• Complete tumor-free margins were obtained in six of seven patients; no adverse events like hemorrhage, perforation, or recurrence were observed.

Conclusions:

• ESD with the Clutch Cutter is an easy, safe, and technically efficient method.
• The CC facilitates effective resection of rectal carcinoid tumors.
• This technique shows promise for improved outcomes in rectal tumor treatment.
