Randomized Trial of Immediate Postoperative Pain Following Single-incision Versus Traditional Laparoscopic Cholecystectomy.

ABSTRACT: We undertook a randomized controlled trial to ascertain if single-incision laparoscopic cholecystectomy (SILC) was more beneficial for reducing postoperative pain than traditional laparoscopic cholecystectomy (TLC). Moreover, the influencing factors of SILC were analyzed.A total of 552 patients with symptomatic gallstones or polyps were allocated randomly to undergo SILC (n = 138) or TLC (n = 414). Data on postoperative pain score, operative time, complications, procedure conversion, and hospital costs were collected. After a 6-month follow-up, all data were analyzed using the intention-to-treat principle.Among SILC group, 4 (2.9%) cases required conversion to TLC. Mean operative time of SILC was significantly longer than that of TLC (58.97 ± 21.56 vs. 43.38 ± 19.02 min, P < 0.001). The two groups showed no significant differences in analgesic dose, duration of hospital stay, or cost. Median pain scores were similar between the two groups 7 days after surgery, but SILC-treated patients had a significantly lower median pain score 6 h after surgery (10-point scale: 3 [2, 4] vs. 4 [3, 5], P = 0.009). Importantly, subgroup analyses of operative time for SILC showed that a longer operative time was associated with greater prevalence of pain score >5 (?100 min: 5/7 patients vs. <40 min, 3/16 patients, P = 0.015).The primary benefit of SILC appears to be slightly less pain immediately after surgery. Surgeon training seems to be important because the shorter operative time for SILC may elicit less pain immediately after surgery.

Project description:BackgroundLocal anaesthetic infiltration is widely used to reduce pain after laparoscopic cholecystectomy (LC). This trial evaluated the effect of depth of local anaesthetic infiltration on postoperative pain reduction after LC.MethodsPatients undergoing elective LC between March 2018 and February 2019 were randomized into no infiltration, subcutaneous infiltration, and rectus sheath infiltration using bupivacaine. The primary outcome was 24-h postoperative cumulative morphine use, and the secondary outcomes were mean 24-h Numerical Rating Scale (NRS) for pain, and nausea, and vomiting. Subgroups were compared and multivariable analyses were performed.ResultsOut of 170 eligible patients, 162 were selected and 150 patients were analysed: 48 in the no-infiltration group, 50 in the subcutaneous infiltration group, and 52 in the rectus sheath infiltration group. The groups had similar clinical features, although mean BMI was higher in the subcutaneous infiltration group (P = 0.001). The 24-h cumulative morphine use in the rectus sheath infiltration group was significantly lower than in the no-infiltration group (P = 0.043), but no difference was observed between the subcutaneous infiltration and no-infiltration groups (P = 0.999). One hour after surgery, the rectus sheath infiltration group had a significantly lower NRS score than the no-infiltration and subcutaneous infiltration groups respectively (P = 0.006 and P = 0.031); however, the score did not differ among the three groups at any of the time points from 2 h after the surgery. The incidence of nausea or vomiting was comparable among the three groups. Multivariable analysis documented that a lower dose of morphine use was associated with rectus sheath infiltration (P = 0.004) and diabetes (P = 0.001); whereas, increased morphine use was associate with age (P = 0.040) and a longer duration of surgery (P = 0.007).ConclusionsLocal anaesthetic infiltration into the rectus sheath reduced postoperative cumulative morphine use and the immediate NRS score in patients undergoing LC; however, the pain scores were comparable 2 h after surgery.Registration numberTCTR20201103002 (http://www.thaiclinicaltrials.org).
