Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Abdominal discomfort is a predominant symptom in patients with pancreatic cancer. Approximately 75% have pain at diagnosis and over 90% in advanced stages. Therefore a major aspect of palliation is provision of adequate pain control. The standard approach to pain management is based on the World Health Organization (WHO) 3-step ladder, beginning with non-opioid analgesics (e.g. non-steroidal anti-inflammatory drugs (NSAIDs) or acetaminophen), followed by weak opioids and then finally strong opioids as necessary. Virtually all patients require escalating doses of opioids during their disease. Adjuvant therapies, including other medications (e.g. trazodone, tricyclic anti-depressants, and bisphosphonates), palliative radionucleotides, external beam radiation, or chemotherapy may also be useful for symptomatic control.
In the last 10 years, EUS-guided celiac plexus neurolysis (EUS-CPN) has been widely practiced for alleviation of pain in patients with pancreatic cancer and has been shown to be effective. At our institution, radiofrequency ablation (EUS-RFA), which involves ablation of celiac ganglia or celiac plexus using a radiofrequency catheter, is being performed to alleviate abdominal pain in pancreatic cancer patients. However currently no comparative studies exist comparing EUS-CPN with EUS-RFA for pain alleviation in pancreatic cancer patients.
In this randomized trial, the investigators will be comparing EUS-CPN with EUS-RFA for pain alleviation in pancreatic patients, in order to determine which technique is better at improving pain in pancreatic cancer patients.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Celiac Plexus Neurolysis
CPN will be undertaken at the celiac space which is located between the aorta and the celiac artery origin. A 22 or 19-gauge Fine Needle Aspiration (FNA) needle is used, and its tip is placed slightly anterior and cephalic to the origin of the celiac artery. Aspiration is first performed using a syringe to ensure that vascular puncture has not occurred. 10 mL Bupivacaine is injected first, followed by 20 mL of 98% alcohol.
Celiac Plexus Neurolysis
This intervention involves accessing the Celiac Plexus Nerve via endoscopic guided ultrasound and then injecting the nerve bundle with bupivacaine.
Radiofrequency Ablation
Once the celiac ganglia are identified on EUS, a 19-gauge FNA needle is inserted into the center of the ganglion or area of celiac plexus under EUS guidance. The radiofrequency (RF) probe (EMcision, Montreal, Canada) is advanced through the FNA needle. Radiofrequency ablation is performed via the probe for 90 seconds, followed by a 90 second rest and repeated as required.
Radiofrequency Ablation
Radiofrequency ablation is performed via the probe for 90 seconds, followed by a 90 second rest. This is repeated until the entire ganglion becomes hyperechoic on EUS.

3. The subject is able to understand and willing to sign an informed consent form prior to the initiation of any study procedures.
4. Abdominal pain typical for pancreatic cancer
5. Cross-sectional imaging findings consistent with pancreatic cancer
6. Pancreatic cancer confirmed by EUS-FNA in patients referred for suspected pancreatic cancer OR Patients with known diagnosis of pancreatic cancer
7. Inoperable pancreatic cancer as determined during EUS or prior CT
Exclusion Criteria
2. Unable to obtain consent for the procedure from the patient
3. Unable to safely undergo EUS for any reason
4. Irreversible coagulopathy (Prothrombin time \> 18 secs, platelet count \< 50,000/ml)
