[A Case of Abdominal Fullness Caused by a Retroperitoneal Bulky Tumor Treated with Epidural Analgesia].

We presented the case of a 63-year-old woman with severe abdominal distention due to recurrent retroperitoneal sarcoma. Further, the rapid progression of the tumor made it difficult to relieve the abdominal distention. Titrated intravenous morphine was administered. Although the dose of morphine was escalated and the patient was sedated, she continued to experience pain. The addition of a continuous epidural analgesic lidocaine to manage the abdominal distention was effective. This case report describes a stepwise approach with continuous epidural analgesia of lidocaine for a bulky tumor- related abdominal distention.
