[Usefulness of an Epidural Catheter with a Subcutaneous Port for Locally Advanced Rectal Cancer Pain Which Was Difficult to Manage with Opioids-A Case Report].

A 56-year-old woman was diagnosed with advanced rectal cancer, with tumor invasion to the sacrum and levator muscle of the anus and multiple lymph node metastasis. After construction of an artificial anus, chemotherapy was started. However, tumor invasion and the cancer pain progressed. Finally, she was hospitalized for pain control; an anesthesiologist planned to insert an epidural catheter. The epidural catheter was placed at the L5-S1 interspace, and continuous administration of 0.2% ropivacaine was started. Cancer pain in the buttocks improved quickly. Therefore, an epidural catheter with a subcutaneous port was placed to prevent catheter-related infection after a long period. The postoperative course was uneventful, and she was discharged from the hospital on the 10th day postoperatively. She could receive home medical care and pain control treatment in an outpatient clinic. Finally, she died due to progression of the rectal cancer, 3 months after placement of the epidural catheter with the subcutaneous port. Some patients with advanced rectal cancer develop cancer pain even though they are sufficiently treated with opioids or palliative radiation therapy. Here, we describe the case of a patient with locally advanced rectal cancer, treated with an epidural catheter with a subcutaneous port for cancer pain that was difficult to manage with opioids alone.
