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. METHODS: Thirty-five consecutive patients were included, 11 underwent SILC (mean ± SEM; age 44.8 ± 3.88 year; BMI 27 ± 1.44 kg/m(2)) and 24 underwent LC (56.17 ± 2.80 year; 31.72 ± 1.07 kg/m(2), p
