Patients with rectal cancer who are not suitable for surgical treatment can use laser as a palliative treatment, and some of these cases can be cured. Objectives of this article: 1. Describe the characteristics of patients treated with laser; 2. Assess the long-term follow-up of Nd:YAG laser treatment; 3. Study the accuracy of endorectal ultrasound (EUS) in primary and follow-up of patients. Materials and Methods: Patients with inoperable or high-risk surgical factors and surgery rejection were selected. Routine endoscopic biopsy, liver ultrasonography, chest X-ray and EUS were performed before the treatment. The size, location, and activity of the tumor were noted for the first time.
