[Effects of RSB and TAPB on Postoperative Pain in Laparoscopic Cholecystectomy].

Background: Several reports have examined meth- ods to control pain after a laparoscopic cholecystec- tomy (LC) and have shown regional anesthesia to be an effective method. We had been performing LC using simple general anesthesia (G); however, in 2013, we adapted a rectus sheath block (RSB), and in 2014, we used a combination of RSB and a subcostal transversus abdominis plane block (TAPB) on the right side. We report on the transition from G to regional anesthesia in LC and its effect on postoperative pain.
