Summary
Endoscopic laser therapy using the Nd:YAG laser offers a highly effective and convenient palliative treatment for advanced colorectal carcinoma. This approach demonstrates significant cost-effectiveness compared to traditional surgery, making it an excellent option for symptom management.
Area of Science:
- Oncology
- Gastroenterology
- Medical Technology
Background:
- Advanced colorectal carcinoma presents challenges for palliative symptom management.
- Existing surgical and nonsurgical options have limitations in efficacy, safety, convenience, and cost-effectiveness.
Purpose of the Study:
- To evaluate endoscopic laser therapy, specifically with the Nd:YAG laser, as an ideal palliative approach for advanced colorectal carcinoma.
- To assess the efficacy, safety, convenience, and cost-effectiveness of this laser therapy compared to traditional surgical resection.
Main Methods:
- Review of international results and institutional experience with Nd:YAG laser therapy for colorectal carcinoma palliation.
- Analysis of complication rates, including bleeding, perforation, abscess, fistula, and stricturing.
- Cost-effectiveness analysis comparing laser therapy with abdominal perineal resection, considering initial and lifetime costs.
Main Results:
- Nd:YAG laser therapy demonstrated high efficacy, with success rates approaching 90%.
- Complications occurred at a rate of 6%, including bleeding, perforation, abscess, fistula, and stricturing.
- Outpatient laser therapy proved to be significantly more cost-effective than abdominal perineal resection, with lifetime costs less than half.
Conclusions:
- Endoscopic laser therapy with the Nd:YAG laser is an excellent, convenient, and cost-effective palliative option for advanced colorectal carcinoma.
- Further research into laser-tissue interactions and new wavelengths is needed to advance laser applications in oncology.
- Selective dye uptake by malignant tissue could enhance targeted ablation efficacy.
