Summary

This study compared different methods of pain control after laparoscopic gallbladder removal. A total of 160 patients were randomly assigned to receive either a unilateral laparoscopic TAP block, local anesthetic infiltration, a combination of both, or no regional anesthesia. Pain scores, use of pain medication, and complications were measured up to 24 hours after surgery. The TAP block group experienced less pain and fewer wound-related problems, showing that this method is safe and effective for postoperative pain relief.

Interventions

PROCEDURE

Unilateral laparoscopic TAP block (0.25% bupivacaine)

Injection of 20 mL 0.25% bupivacaine into the transversus abdominis plane under direct laparoscopic vision.

PROCEDURE

Local anesthetic infiltration (0.25% bupivacaine)

Injection of 20 mL 0.25% bupivacaine distributed across trocar insertion sites under laparoscopic guidance.

PROCEDURE

Combined TAP block and local anesthetic infiltration (0.25% bupivacaine)

10 mL of 0.25% bupivacaine given as a TAP block and 10 mL administered as local infiltration at trocar sites.
