SILS cholecystectomy, as well as the invisible scar, has significantly lower abdominal and shoulder pain scores, especially after the first 24 h postoperatively, when this pain is nonexistent. (Registration Clinical Trial number: NTC00872287, www.clinicaltrials.gov ).

Preincisional local infiltration plus intraperitoneal infusion of ropivacaine at the beginning of LC combined with normal saline infusion at the end of the procedure is a safe and valid method for reducing pain after LC.

A prophylactic stoma mesh did not reduce the rate of clinically or computed tomography-verified parastomal hernias. High BMI was associated with an increased risk of parastomal hernia formation regardless of prophylactic stoma mesh.

The inflammatory response and the resultant stress response are significantly less during laparoscopic colectomy than during open colectomy for colorectal cancer. This is an obvious short-term clinical benefit for the patient, providing tinder for further study to investigate the long-term results of laparoscopic colectomy versus open colectomy for colorectal cancer.

Higher inflammatory reaction in LESS cholecystectomy could be the result of greater tension on the tissues. More studies are needed to conclude if this has a significant clinical expression.

LNF combined with posterior gastropexy may prevent postoperative paraesophageal or sliding herniation in surgical treatment of GERD, providing better early and long-term postoperative results. (Registered Clinical Trial number: NCT00872755. www.clinicaltrials.gov .).

Splenic flexure mobilization can provide a tension-free anastomosis and sufficiently vascularized anastomosis in laparoscopic colorectal surgery for distal colon pathology, with no impact on immediate postoperative outcomes, despite longer operative time.

The present study confirms the results of previous studies, that the inflammatory immune response and surgical stress are significantly less after laparoscopic colectomy versus open colectomy for colorectal cancer. More investigation is needed to study if surgical stress has any influence on survival of these patients.
