BACKGROUND AND OBJECTIVES: To report and discuss the effect, complications and mortality of cool-tip radiofrequency ablation (RFA) for unresectable pancreatic cancer. METHODS: During October 2003 to July 2004, sixteen patients with unresectable pancreatic cancer were treated by open cool-tip RFA. One-half of the 16 patients had tumors located in the pancreatic head. A 5-mm minimum safe distance between RFA site and major peripancreatic vessels was kept to avoid injury to the vessels. RESULTS: Six of twelve patients with back pain got pain relief postoperatively. Pancreatic fistula occurred in three patients (18.8%) and healed smoothly in 7-10 days with routine abdominal drainage. The mortality was 25% (4/16). In the four death cases, tumors were all located in the pancreatic head; three patients with tumor close to portal vein died suddenly of massive gastrointestinal hemorrhage on the 4th, 30th, 40th postoperative day respectively and a 79-year-old patient died of acute renal failure on the 2nd postoperative day. CONCLUSIONS: Standard use of cool-tip RFA was dangerous for pancreatic head cancer close to portal vein, in which a 5-mm minimum safe distance between RFA site and major peripancreatic vessels might not be enough to avoid injury to the vessels.
