Résumé
The purpose of the present study was to challenge the hypothetical advantage of single port laparoscopy (SPL) over conventional laparoscopy by measuring prospectively the morbidity specifically related to conventional trocar sites (TS). From November 2010 to December 2011, 300 patients undergoing various laparoscopic procedures were enrolled. Patient, surgery, and trocar characteristics were recorded. We evaluated at three time points (in-hospital and at 1 and 6 months postoperatively) specifically for each TS, pain (Visual Analog Scale), morbidity (infection, hematoma, hernia), and cosmesis (Patient Scar Assessment Score; PSAS). Patients designated their "worst TS," and a composite endpoint "bad TS" was defined to include any adverse outcome at a TS. We analyzed 1,074 TS. Follow-up was >90 %. Pain scores of >3/10 at 1 and 6 months postoperatively, were reported by 3 and 1 % of patients at the 5 mm TS and by 9 and 1 % at the larger TS, respectively (5 mm TS vs larger TS; p = 0.001). Pain was significantly lower for TS located in the lower abdomen than for the upper abdomen or the umbilicus (p = 0.001). The overall complication rate was
