Summary
A new colorectal tumor localization protocol without endoscopic tattooing achieved 100% accuracy in 788 patients. This method improves efficiency and avoids drawbacks associated with traditional endoscopic tattooing in laparoscopic surgery.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Gastroenterology
Background:
- Tumor localization is critical for laparoscopic colorectal surgery.
- Endoscopic tattooing is a common but not flawless method for tumor marking.
- Few studies have evaluated alternatives to endoscopic tattooing.
Purpose of the Study:
- To assess the accuracy and efficiency of a novel tumor localization protocol.
- To evaluate a method that avoids traditional endoscopic tattooing.
- To determine if this protocol enhances laparoscopic colorectal surgery outcomes.
Main Methods:
- A new tumor localization protocol was applied to 788 patients with colorectal cancer or polyps.
- Laparoscopic colorectal resections were performed using the protocol.
- Localization accuracy was verified through intraoperative assessment and pathology.
Main Results:
- The protocol demonstrated 100% accuracy in tumor localization.
- Drawbacks of endoscopic tattooing, such as misplacement, were eliminated.
- Preoperative endoscopic clip placement was reduced to 16.6%.
- Intraoperative colonoscopy became a planned procedure, not a fallback.
- Camera port misplacement was avoided in 2.3% of cases.
Conclusions:
- The developed tumor localization protocol significantly improves accuracy and efficiency.
- This tattooing-free approach offers a superior alternative for colorectal tumor localization.
- Enhanced precision in laparoscopic colorectal surgery is achievable with this protocol.
