  1. LC = laparoscopic cholecystectomy; NW + NP = no wound anesthetic and no intraperitoneal anesthetic use; NW + P = no wound anesthetic but intraperitoneal anesthetic use; W + NP = wound anesthetic but no anesthetic use; W + P = wound anesthetic and intraperitoneal anesthetic use.
  2. ap < 0.05, compared to NW + NP group patients (based on the results of the post hoc Kruskal-Wallis test).
  3. bp < 0.05, compared to NW + NP group patients (based on the analysis of variance [ANOVA] post hoc Scheffe’s test results).
