Opioid withdrawal presenting only nausea during tapering of oxycodone after celiac plexus block: a case report

Pancreatic cancer is recognized as one of the most painful types of malignancy. Most patients with severe cancer pain are treated with maximum opioid for pain relief. However, they may suffer from side effects of opioid use. Celiac plexus block (CPB) is an effective treatment for patients with visceral pain arising from malignancy, such as pancreatic cancer (1,2). CPB may allow for a reduction in opioid dosage, and may alleviate some of the unwanted side effects of opioid use (1,2)
