Abstract


Objective
The umbilicus is a single, painful incisional site on the abdomen during trans-umbilical single-port access laparoscopic surgery. Previously, we found that periumbilical lidocaine could reduce postoperative pain. This study aimed to compare the efficacy of bupivacaine and lidocaine in reducing pain.
Methods
We performed a retrospective analysis in a study group (Bupivacaine group, 100 patients who received periumbilical infiltration of bupivacaine before their incisional site repair completion) and control group (Lidocaine group, 100 patients who received lidocaine at their incisional site repair completion). We compared postoperative pain based on the numerical rating scale (NRS) between propensity score-matched Bupivacaine-treated (n=50) and Lidocaine-treated (n=50) patients.
Results
The postoperative pain scores based on the NRS were not significantly different between the 2 groups until 12 hours post-operation. However, 24 hours post-operation, the Bupivacaine group showed significantly lower pain than the Lidocaine group (24 hours, 1.76±1.07 vs. 2.53±1.11 NRS, P<0.001; 48 hours, 0.84±0.85 vs. 2.16±0.85 NRS, P<0.001).
Conclusion
Periumbilical infiltration of bupivacaine has a longer acting efficacy on reducing postoperative surgical pain than that of lidocaine.
