NCT ID NCT07409688
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests two methods of giving the numbing drug bupivacaine to reduce pain after keyhole gallbladder removal. One method sprays the drug inside the belly, the other injects it into the skin around the small cuts. The trial will enroll 100 adults and measure pain scores and need for extra pain relief.
