Summary
This study introduces a new endoscopic fluorescent band ligation method for precise tumor identification in minimally invasive surgery. The technique enables accurate localization of gastrointestinal tumors, improving surgical outcomes.
Area of Science:
- Surgical Innovation
- Medical Imaging
- Gastroenterology
Background:
- Accurate tumor localization is critical for effective minimally invasive surgery.
- Current methods may lack the precision needed for complex gastrointestinal procedures.
- Novel techniques are required to enhance intraoperative tumor site identification.
Purpose of the Study:
- To develop and evaluate a novel endoscopic fluorescent band ligation method.
- To assess the rapid and accurate identification of tumor sites during surgery.
- To improve the precision of tumor excision in minimally invasive gastrointestinal procedures.
Main Methods:
- Development of fluorescent rubber bands using indocyanine green (ICG).
- Utilized a near-infrared fluorescence laparoscopy system with a dual light source (LED and 785-nm laser).
- Endoscopic placement of fluorescent bands on porcine stomach and colon mucosa, followed by laparoscopic assay.
Main Results:
- Fluorescent bands were clearly identified in real-time on fluorescence images.
- The system successfully distinguished multiple marked bands on mucosal surfaces.
- Sufficient resection margins were achieved around the fluorescent bands in resected specimens.
Conclusions:
- Novel endoscopic fluorescent bands allow for rapid and accurate localization during surgery.
- This method facilitates precise excision of target sites in minimally invasive gastrointestinal surgery.
- The technique holds potential for improving oncologic outcomes in gastrointestinal cancer surgery.
