Brief Summary

Many cancer patients suffer from intractable pain and which is often suboptimally controlled by even strong opioid analgesics. Coeliac plexus neurolysis (CPN) is procedure which intended to permanently destroy the nociceptive pathway that transmits the pain caused by the tumour. It can be with different approaches, such as percutaneously guided by fluoroscopy, echo-endoscopically or surgically with endoscopic approach being the more popular one in many centers equipped with echo-endoscopic services. The effect of CPN has been well established by some retrospective series. The overall response rate to CPN ranges from 70-90%, however, the analgesic effect is limited and up to roughly around 3 months. It is believed that the short-lasting analgesic effect is related to incomplete neurolysis by absolute alcohol injection. Recently, radiofrequency ablation (RFA) of coeliac plexus has been introduced as another mode of CPN. So far, only one small single center randomized controlled trial (RCT) suggesting superior performance in favour to CPN using RFA. This result has to be validated and by a RCT with larger sample size. In addition, data concerning the quality of life (QOL) improvement and cost-effectiveness need to be further elucidated. Therefore, the aim of this study is to perform a RCT to look into these issues.

ACTIVE COMPARATOR

Endoscopic Ultrasound Guided Coeliac Plexus Block

Drug: Alcohol injection

EUS-CPA

ACTIVE COMPARATOR

Endoscopic Ultrasound Guided Coeliac Plexus Radiofrequency Ablation

Device: Radiofrequency Ablation

Interventions

Chemical ablation is performed by injection of 10 mL of 0.25% bupivacaine, followed by 10 mL of 98% dehydrated alcohol using a 22G FNA needle (Cook and Olympus)

Also known as: Chemical Ablation
EUS-CPB

coeliac plexus is identified and punctured with 19G EUSRA RFA needle with 10W-30W of energy for 10-50s bilaterally or unilaterally depends on individual anatomical characteristics.

Also known as: RFA
EUS-CPA

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥18 year-old
  • Patients who give informed consent to the study
  • Suboptimal pain control with regular analgesics
  • Inoperable cancer of pancreas, biliary system and liver (both primary or secondary)

You may not qualify if:

  • Patients who refuse to give consent
  • Patients aged \<18 years
  • EUS not possible due to:
  • Problem related to scope insertion such as trismus, stenosis of the upper GI tract
  • Coagulopathy with INR \>1.5 or platelet count \< 70
  • Low oxygen saturation or extreme blood pressure render endoscopic procedure unsafe
