The purpose of this study was to investigate the effectiveness of preemptive effect of rectus
sheath block (RSB) and intercostal nerve block (ICNB) on postoperative visceral pain in

After induction of general anesthesia, group of patient is decided randomly. In Group pre,
RSB and ICNB are performed with 0.25% Ropivacaine 40ml before the operation. In Group post,
RSB and ICNB are performed with 0.25% Ropivacaine 40ml after the operation.
