Summary
Endoscopic Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser treatment effectively reduces rectal bleeding in patients with chronic radiation proctitis. This safe therapy offers significant relief for mild to moderate cases, decreasing transfusion needs and improving patient outcomes.
Area of Science:
- Gastroenterology
- Oncology
- Medical Technology
Background:
- Chronic radiation proctitis is a severe complication following pelvic radiotherapy.
- It often causes significant rectal bleeding unresponsive to conventional treatments.
- Surgical and local drug therapies show limited efficacy.
Purpose of the Study:
- To evaluate the efficacy and safety of endoscopic Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser treatment.
- To identify patient subgroups who may benefit from this intervention.
- To assess the impact on bleeding severity and transfusion requirements.
Main Methods:
- Nine patients with chronic radiation proctitis and rectal bleeding post-radiotherapy were enrolled.
- Endoscopic Nd:YAG laser therapy was administered monthly until bleeding cessation.
- Bleeding and transfusion data were collected pre-treatment, during treatment, and post-treatment.
Main Results:
- An average of three Nd:YAG laser sessions were required per patient.
- Pre-treatment transfusion rates averaged 1.3 units/patient/month, dropping to minimal post-treatment.
- Six patients experienced reduced bleeding to occasional spotting; no complications were reported.
Conclusions:
- Endoscopic Nd:YAG laser therapy is a safe and effective treatment for radiation-induced proctitis.
- The procedure significantly reduces bleeding and transfusion dependency.
- It offers a viable therapeutic option for patients with mild to moderate symptoms.
