Values are presented as medians (interquartile ranges) and arithmetic mean±standard deviation (SD). The 1-hour VAS score was lower in the BLTAP group than in the SA (p=0.002) and ULTAP (p=0.0245) groups. In the comparison of the score changes calculated by taking the difference according to the 1-hour score among groups, the change was higher in the SA group than in the BLTAP group (p=0.038).

^∆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
