Trocar-site Infiltration Versus TAP-block

Trocar-site Infiltration With Ropivacaine Versus Tranversus Abdominis Plane Block Following Laparoscopic Cholecystectomy: a Double-blinded, Randomized-controlled Trial

For symptomatic gall bladder disorders (cholelithiasis and cholecystitis), laparoscopic cholecystectomy (LC) has been considered as the gold standard treatment. However, these minimally invasive technique is associated with acute moderate pain during the 24 hours postoperative, which is routinely managed using opioids. The transversus abdominis plane (TAP) block has been used as part of a multimodal analgesia strategy. Besides, Wang et al found that TAP block is more effective than a conventional pain control, but not significatively different from another local incisional pain control that is port site infiltration.So, the aim of this study, is to compare the analgesic efficacy and safety of trocar-site infiltration with ropivacaine with ultrasound-guided TAP block following laparoscopic cholecystectomy when used as part of multimodal analgesia.
