Local infiltration versus laparoscopic-guided transverse abdominis plane block in laparoscopic cholecystectomy: double-blinded randomized control trial.

Background: Transverse abdominal plane block (TAP) is a new technique of regional block described to reduce postoperative pain in laparoscopic cholecystectomy (LC). Recent reports describe an easy technique to deliver local anesthetic agent under laparoscopic guidance.

Methods: This randomized control trial was designed to compare the effectiveness of additional laparoscopic-guided TAP block against the standard full thickness port site infiltration.
