Summary
Neodymium YAG (Nd:YAG) laser therapy effectively manages gastrointestinal cancers by relieving obstruction and controlling bleeding. This approach reduces hospital stays and costs, offering a safe alternative to colostomy for nonresectable cases.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Medical Technology
Background:
- Malignant neoplasms in the gastrointestinal tract often cause obstruction and hemorrhage.
- Traditional treatments may involve significant morbidity and mortality.
- Neodymium YAG (Nd:YAG) laser therapy presents a minimally invasive option.
Purpose of the Study:
- To evaluate the efficacy of Nd:YAG laser therapy for gastrointestinal cancers.
- To assess its role in preresectional therapy (PR) for resectable tumors.
- To determine its benefit in managing nonresectable (NR) or metastatic disease.
Main Methods:
- Retrospective analysis of 53 patients treated between 1985 and present.
- Nd:YAG laser therapy used for preresectional treatment in 29 patients.
- Nd:YAG laser therapy used for palliation in 24 nonresectable patients.
Main Results:
- Successful obstruction relief and hemorrhage control were achieved.
- One laser-related complication (1.8%) occurred; no significant morbidity/mortality in the PR group.
- Significant reduction in length of stay and total hospital costs compared to initial series.
Conclusions:
- Nd:YAG laser therapy is effective for preresectional treatment of colonic/rectal tumors, avoiding diversion.
- It serves as a safe alternative to permanent colostomy for nonresectable disease.
- Laser therapy offers significant cost and length-of-stay benefits.
