Background and Aims
Acute-phase proteins and inflammatory cytokines mediate measurable responses to surgical trauma, which are proportional to the extent of tissue injury and correlate with post-operative outcome. By comparing systemic stress following multi-port (LC) and single-incision laparoscopic cholecystectomy (SILC), we aim to determine whether reduced incision size induces a reduced stress response.
Thirty-five consecutive patients were included, 11 underwent SILC (mean ± SEM; age 44.8 ± 3.88 year; BMI 27 ± 1.44 kg/m2) and 24 underwent LC (56.17 ± 2.80 year; 31.72 ± 1.07 kg/m2, p < 0.05). Primary endpoint measures included levels of interleukin-6 and C-reactive protein measured pre- and post-operatively. Length-of-stay (LOS) and postoperative morbidity were secondary endpoints.
No statistically significant differences were found between SILC and LC for interleukin-6 and C-reactive protein levels, LOS and duration of surgery. There was also no correlation between systemic stress response and operative parameters. There were no intra-operative complications.
SILC appears to be a safe, feasible technique with potential advantages of cosmesis, reduced incisional pain, and well-being recommending its use. These data indicate no difference in systemic stress and morbidity between SILC and LC. A larger, multi-centred, randomised prospective trial is warranted to further investigate and confirm this finding.
