【Abstract】 Objective The effects and the complications of anhydrous alcohol intra-abdominal coeliac plexus block were studied for treating unresectable pancreatic cancer pain. Methods From Jan.2001 to Sep.2005, 61 patients with severe pancreatic cancer pain and accompanied gastrointestinal tract obstruction were treated by anhydrous alcohol intra-abdominal coeliac plexus block and palliative surgical therapy. Pain-relief, KPS and complications in 3 months after operation were observed. Results The cancer pain in all patients was controlled in one week after the block (P＜0.05). KPS was improved (P＜0.05). Three months after operation, 45(86.5%) patients were without pain or with only light pain. There were no severe complications. Conclusion Anhydrous alcohol intra-abdominal coeliac plexus block is a method with safe and good effective and less complications for the treatment of pancreatic carcinomatous pain.
