Using a fluorescent clip to locate colon tumors during surgery

Efficacy and Safety of Fluorescent Surgical Marker Clip for Tumor Localization in Laparoscopic Colorectal Surgery for Colorectal Cancer Patients : Multi-center, Randomized, Single-blind, Prospective, Non-Inferiority Trial

Phase 2 Interventional Seoul National University Hospital · NCT06714292

This study is testing a new fluorescent clip to see if it helps doctors find colon tumors more accurately during surgery compared to the traditional dye method.

What this trial studies

This study evaluates the effectiveness of a fluorescent surgical marker clip for accurately localizing tumor sites in the colon during minimally invasive colorectal surgery. Participants will be randomly assigned to receive either the fluorescent clip or the traditional Indocyanine Green (ICG) dye for tumor marking. The study aims to compare the safety and effectiveness of the clip against the dye method, assessing any potential side effects associated with the clip. The goal is to improve localization techniques for better surgical outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 19 years or older with colonic neoplasms who are planning minimally invasive surgery and require localization of the lesion.

Not a fit: Patients who are planning a total proctocolectomy or have contraindications for colonoscopy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the accuracy of tumor localization, leading to improved surgical outcomes for patients with colon cancer.

How similar studies have performed: While the use of fluorescent markers in surgery is gaining interest, this specific approach comparing a fluorescent clip to ICG dye is relatively novel and has not been extensively tested in prior studies.
