This study aimed to compare the efficacy of the surgical technique versus the per cutaneous computed tomographic guided technique of celiac plexus neurolysis for pain management in unresectable pancreatic cancer . all patients suffering from pain of pancreatic cancer with VAS≥5 undergoing laparotomy and proved to be unresectable either undergoing biopsy or bypass surgery will receive celiac plexus neurolysis either intraoperative or post operative CT guided . All patients will be managed by systemic analgesic if the block not sufficient . In this study we will give the patient the analgesic according to WHO recommendation as starting by non steroidal anti inflammatory drugs as diclofenac sodium, if it is not sufficient we will give them opioids as tramadol, and for neuropathic pain gabapentin. All drugs will be given with escalating dose . Failed block defined as change in VAS between VAS BASELINE AND ONE MONTH ≤ 3 may need to repeat the block by percutaneous technique .
