title: Successful treatment of anal tumors with CO2 laser in elderly, high-risk patients.
abstract: The central issue in elderly surgery remains the operative risk, which is usually a direct factor of age, ASA classification, and other pathologies, especially cardiovascular diseases. It is the surgeon's role to define properly the risks involved with a patient and to anticipate the involved operative mortality. Based on this, we performed CO2 laser fulguration of anal canal tumors in 10 patients suffering from either squamous cell or adenocarcinoma localized up to 4 cm from the anus. The rationale was to avoid prohibitive operative and anesthetic risk, achieve local control of disease and improve quality of life by avoiding surgical convalescence and an otherwise certain colostomy. All patients underwent fulguration (25-30 W) every 3-4 months. Complications included minor pain and bleeding. Three patients required operation (Hartman's pouch) within 2 1/2 years due to continuous tumor bleeding and stricture of the anal canal. The remaining 7 patients were treated regularly and satisfactorily by fulguration and the mean survival in this group was 8 years (in all cases the causes of death were unrelated to the procedure or the tumor). We conclude that CO2 laser fulguration of anal canal tumors in elderly, high-risk patients represents an invaluable option of treatment, while avoiding major operative risk, controlling the local spread of disease, maintaining physiological bowel function, and avoiding colostomy. Most importantly, the main dividends of the study are patient satisfaction and maintenance of good quality of life.
