Nerve-Block procedure tested against severe pancreatic and stomach cancer pain
NCT ID NCT07825870
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers are studying whether a procedure called fluoroscopy-guided transdiscal splanchnic nerve neurolysis can safely reduce severe upper abdominal pain in adults with pancreatic, gastric, or hepatobiliary cancer. Participants first receive a diagnostic nerve block with local anesthetic; those who get at least 50% pain relief go on to have the nerve treated with alcohol or phenol under X-ray guidance. The study tracks pain scores, opioid use, functional status, quality of life, and complications over six months to see how well the approach works and how long relief lasts.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- chemical neurolysis of the splanchnic nerve using alcohol or phenol
- What this could lead to
- If it works, this could offer a way to ease severe cancer pain and lower reliance on opioid medicines for people with upper abdominal tumors.
- What could go wrong
- This is a small, single-center study with no comparison group, so results may not apply broadly. Nerve-block procedures can cause bleeding, infection, low blood pressure, or nerve injury, and pain relief may fade over time.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥ 18 years. Confirmed diagnosis of pancreatic, gastric, or hepatobiliary malignancy with epigastric/upper abdominal pain. Baseline NRS ≥ 7 despite optimized pharmacotherapy, or intolerable opioid side effects. ≥ 50% pain relief on diagnostic splanchnic nerve block. Able to provide informed consent. Exclusion Criteria: * Coagulopathy (INR \> 1.5, platelets \< 50,000/µL). Local or systemic infection. Uncontrolled hypotension or severe cardiopulmonary compromise precluding prone positioning. Intestinal obstruction. Known allergy to contrast, local anesthetic, or the neurolytic agent. Patient refusal.
