Preoperative Indocyanine Green Tattooing for Robotic-Assisted Surgery in Rectal Cancer

Area of Science:

• Surgical Oncology
• Medical Imaging
• Minimally Invasive Surgery

Background:

• Accurate preoperative localization of rectal cancer is vital for successful tumor resection.
• Traditional methods like India ink tattooing and clipping have significant limitations, including surgical field obstruction and impracticality for minimally invasive procedures.
• Existing techniques pose risks such as peritonitis and adhesive bowel obstruction.

Purpose of the Study:

• To evaluate the effectiveness of preoperative indocyanine green (ICG) marking for precise tumor localization in robot-assisted rectal cancer surgery.
• To demonstrate how ICG fluorescence overcomes the drawbacks of conventional preoperative marking methods.

Main Methods:

• Utilizing the fluorescence properties of indocyanine green (ICG) for preoperative tumor marking.
• Applying the ICG fluorescence method during robot-assisted rectal colorectal surgery.

Main Results:

• Preoperative ICG marking allows for precise identification of the tumor site.
• The fluorescence technique enhances surgical accuracy and minimizes intraoperative risks.
• This method facilitates optimal oncological outcomes in rectal cancer surgery.

Conclusions:

• Preoperative indocyanine green tattooing is a valuable enhancement for rectal cancer surgery, especially in robot-assisted approaches.
• The technique offers a promising alternative to traditional methods, improving tumor localization and patient outcomes.
• ICG fluorescence provides a safe and effective means for preoperative marking in robot-assisted rectal cancer surgery.
