Values are presented as medians (interquartile ranges) and arithmetic mean±standard deviation (SD). The one-hour VAS score in the BLTAP group was lower than that in the SA group (p=0.002). In terms of the change in VAS scores from one-hour scores, there were no significant differences among groups.

^∆Difference score calculated according to the first-hour VAS score.

VAS: visual analog scale,

SA: standard analgesia,

LA: local anesthesia,

BLTAP: bilateral laparoscopic-assisted transversus abdominis plane block,

ULTAP: unilateral laparoscopic-assisted transversus abdominis plane block
