The use of laser in rectal surgery

Area of Science:

• Surgical Oncology
• Laser Medicine

Background:

• Rectal tumors present surgical challenges, particularly in high-risk patients.
• Minimally invasive techniques are sought to improve outcomes and reduce patient burden.

Purpose of the Study:

• To evaluate the efficacy and safety of carbon dioxide (CO2) laser excision for rectal tumors.
• To assess the CO2 laser's utility in treating both benign and malignant rectal conditions.

Main Methods:

• Ten patients with rectal tumors underwent surgical excision using a Sharplan 733 CO2 laser.
• Procedures included excision, vaporization, or fulguration of tumor tissue.
• Outcomes were assessed based on hemostasis, anesthesia requirements, and complications.

Main Results:

• CO2 laser surgery provided sharp tissue dissection and effective hemostasis.
• Anesthesia was not required in cooperative patients, and no procedure-related mortality or morbidity occurred.
• Five patients with villous adenomas showed successful resection with one recurrence; five with inoperable carcinoma experienced good palliation.

Conclusions:

• The CO2 laser is a valuable tool for rectal tumor surgery, especially for benign tumors and palliative treatment.
• It is particularly beneficial for elderly or medically compromised patients.
• Further investigation into long-term outcomes for CO2 laser rectal surgery is warranted.
