The LESS single-port (SP) operations demand a bigger incision than LC surgery. However, there were no differences in healing, wound infections, and hernia development. We found a tendency of less postoperative pain associated with LESS/SP than with LC.

LESS cholecystectomy requires a larger size incision than LC. We found a tendency of less postoperative pain following LESS cholecystectomy than LC. There was also a tendency toward lower early inflammatory impact following LESS cholecystectomy versus LC.

Objective: to evaluate and compare the early postoperative period systemic inflammatory response between elderly and non-elderly patients submitted to laparoscopic cholecystectomy, mainly performing a quantitative analysis of interleukin-6 (IL-6), a marker of inflammatory activity systemic. Methods: we compared a series of cases over a period of six months at the Gaffrée and Guinle University Hospital of the Federal University of the State of Rio de Janeiro, involving 60 patients submitted to elective laparoscopic cholecystectomy. We used non-probabilistic sampling for convenience, selecting, from the inclusion criteria, the first 30 patients aged 18-60 years, who comprised group I, and 30 patients with age equal to or greater than 60 years, who formed group II. Results: the 60 patients involved were followed for at least 30 days after surgery and there were no complications. There was no conversion to open surgery. The values of the medians found in the IL-6 dosages for the preoperative period, three hours after the procedure and 24 hours after surgery were, respectively, 3.1 vs. 4.7 pg/ml, 7.3 vs. 14.1 pg/ml and 4.4 vs 13.3 pg/ml. Conclusion: Elderly patients were more responsive to surgical trauma and had elevated IL-6 levels for a longer period than the non-elderly group.

Background: Surgeries with single port access have been gaining ground among surgeons who seek minimally invasive procedures. Although this technique uses only one access, the incision is larger when compared to laparoscopic cholecystectomy and this fact can lead to a higher incidence of incisional hernias. Aim: To compare the incidence of incisional hernia after laparoscopic cholecystectomy and by single port. Methods: A total of 57 patients were randomly divided into two groups and submitted to conventional laparoscopic cholecystectomy (n=29) and laparoscopic cholecystectomy by single access (n=28). The patients were followed up and reviewed in a 40.4 month follow-up for identification of incisional hernias. Results: Follow-up showed 21,4% of incisional hernia in single port group and 3.57% in conventional technique. Conclusions: There was a higher incidence of late incisional hernia in patients submitted to single port access cholecystectomy compared to conventional laparoscopic cholecystectomy.
