Nerve block may cut opioid need in bile duct procedure, small study suggests
NCT ID NCT06618781
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed observational study in 52 adults compared standard sedation alone to sedation plus a lateral quadratus lumborum block (an injection of numbing medicine near the lower back muscles) during percutaneous transhepatic cholangiography, a procedure to diagnose or treat bile duct blockages. The main goal was to see if the block reduces the amount of opioid painkiller needed during the procedure. Researchers also tracked pain scores, recovery time, and side effects.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
bupivacaine and lidocaine (local anesthetics)
What this could lead to
If results are positive, this could support using quadratus lumborum blocks to reduce opioid needs and improve recovery in similar procedures.
What could go wrong
This is a small observational study (52 patients) with no randomization or blinding, so results may be influenced by bias and may not apply broadly.
