Summary
A new near-infrared (NIR) fluorescent endoscopic clip aids robot-assisted surgery by enabling precise tumor location identification in gastrointestinal cancer patients. This technology improves surgical accuracy for early-stage cancers.
Area of Science:
- Surgical Oncology
- Medical Imaging
- Gastroenterology
Background:
- Accurate intraoperative tumor localization is challenging in robot-assisted surgery, particularly for early-stage gastrointestinal cancers.
- Current methods may lack precision, leading to difficulties in defining resection margins.
Purpose of the Study:
- To evaluate the feasibility and accuracy of a novel near-infrared (NIR) fluorescent endoscopic clip.
- To assess its utility in guiding robot-assisted surgery for gastrointestinal cancer.
Main Methods:
- Preoperative placement of NIR fluorescent endoscopic clips to mark resection margins in six gastrointestinal cancer patients.
- Intraoperative detection of clip fluorescence using a NIR imaging system during robot-assisted surgery.
Main Results:
- Successful detection of NIR fluorescent signals from the clips in all six patients.
- Fluorescence visualization from the serosal surfaces enabled quick and accurate identification of the resection line.
- No significant demographic differences (age, sex, BMI) affected NIR fluorescence detection.
Conclusions:
- The novel NIR fluorescent clip is a promising tool for intraoperative tumor localization in robot-assisted gastrointestinal cancer surgery.
- This technology enhances the accuracy of identifying resection margins, potentially improving surgical outcomes.
