Prospective randomized controlled trial comparing standard analgesia with combined intra-operative cystic plate and port-site local anesthesia for post-operative pain management in elective laparoscopic cholecystectomy

摘要

Various mechanisms, including somatic and visceral nociceptive stimulation, have been suggested as a cause for pain after laparoscopic cholecystectomy (LC). We therefore conducted a prospective randomized controlled trial (PRCT) to evaluate whether somatovisceral pain blockade reduces pain after LC.
