This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing two different ways to numb nerves around your abdomen to help control pain after liver surgery. One approach, called a retrolaminar block, numbs nerves in your back near the spine using ultrasound guidance. The other approach, called a subcostal transversus abdominis plane block, numbs nerves in the abdominal wall. Both use a local anesthetic called bupivacaine to block pain signals.
Liver surgery can cause significant pain after the operation. Doctors want to find the most effective nerve-blocking technique to help patients recover comfortably and reduce the need for other pain medications.

If you join this trial, you will be randomly assigned to receive one of the two nerve-blocking techniques before your liver surgery. A doctor will use ultrasound to guide the needle and inject numbing medication on both sides of your body. You will also receive standard epidural pain management during and after surgery. The research team will then monitor your pain levels and how well each technique works to control your pain after surgery.
