BACKGROUND Postoperative pain, nausea, and vomiting are the most common side effects of laparoscopic cholecystectomy (LC). In the present study, we investigated the differences in postoperative pain, nausea, and vomiting between Veress needle and direct trocar entry methods among patients undergoing LC. METHODS 96 patients with gallstones were studied. They were randomly divided into two groups: the patients in the first group (n = 48) were insufflated 8.1 liters per minute CO 2 gas by direct trocar port, and the patients in another group (n = 48) were insufflated 2.1 liters per minute CO 2 gas by Veress needle. Pain intensity, nausea, and vomiting were assessed at 20 minutes, 4 hours, and 12 hours after the operations. RESULTS The duration of CO 2 gas insufflation in Veress needle was 88.7 ± 10.7 seconds and indirect trocar was 16.6 ± 1.6 seconds. Visual analog scale (VAS) score significantly reduced in Veress needle compared with direct trocar (0.39 ± 0.98 vs. 1.68 ± 1.48) at 20 min after the operation, while there was no difference at 4 hours and 12 hours after the operation. The requirement and dose of pethidine injection were significantly lower in Veress needle than direct trocar. In addition, nausea and vomiting occurred in Veress needle less than direct trocar at 20 min, 4 hours, and 12 hours after LC. CONCLUSION Pain intensity just in the short term after LC in the group with CO 2 gas insufflation in Veress needle was significantly less than the other group, while nausea and vomiting were significantly less during the whole follow-up periods in the group with CO 2 gas insufflation in Veress needle.
