Summary
This study looked at whether a TAP block (a type of nerve block) can reduce pain after laparoscopic gallbladder removal. Sixty adults were split into two groups: one got the TAP block with numbing medicine after surgery, the other did not. Researchers measured pain levels and how long before patients needed extra painkillers.
