AbstractWe report a successful case of subarachnoid phenol block therapy in a patient with refractory rectal tenesmus caused by metastatic breast cancer. A 50-year-old woman with pelvic metastasis of breast cancer had the constant desire for defecation and anal discomfort, although analgesics including opioids relieved her from low abdominal and anal pain. Computed tomography revealed rectal invasion of metastatic breast cancer and the diagnosis of tumor-related rectal tenesmus was made. Symptoms of rectal tenesmus were severe and drug-resistant. Subarachnoid phenol block in the sitting position, which was neurolytic saddle block and expected to inhibit rectal reflex, was performed and her symptom was dramatically relieved. The effect of the block continued until she died 19 days after. To our knowledge, we first report subarachnoid phenol block therapy for a patient with pelvic-tumor related rectal tenesmus.
