Randomized Controlled Trial Comparative Study
Performance curve of basic skills in single-incision laparoscopy versus conventional laparoscopy: is it really more difficult for the novice?
Single-incision laparoscopy is a step forward toward nearly scarless surgery. Concern has been raised that single-incision laparoscopy is technically more challenging than conventional laparoscopy. This study researched the performance curves of novice trainees for single-incision laparoscopy (SILS) versus conventional laparoscopy for performing two basic tasks on a box trainer. ⋯ This study showed a significant improvement in basic skills for both the SILS and conventional laparoscopy settings after 11 repetitions. These data suggest that box training shows no significant difference between conventional laparoscopic and single-incision laparoscopic settings in terms of error or time in performing basic tasks at a low complexity level for the novice. These data also show significant improvement in basic skills over a relatively short period.

Review Meta Analysis Comparative Study
Single-incision laparoscopic surgery (SILS) vs. conventional multiport cholecystectomy: systematic review and meta-analysis.
Single-incision laparoscopic surgery (SILS) has gained increasing attention due to the potential to maximize the benefits of laparoscopic surgery. The aim of this systematic review and pooled analysis was to compare clinical outcome following SILS and standard multiport laparoscopic cholecystectomy for the treatment of gallstone-related disease. ⋯ The results of this meta-analysis demonstrate that single-incision laparoscopic cholecystectomy is a safe procedure for the treatment of uncomplicated gallstone disease, with postoperative outcome similar to that of standard multiport laparoscopic cholecystectomy. Future high-powered randomized studies should be focused on elucidating subtle differences in postoperative complications, reported postoperative pain, and cosmesis following SILS cholecystectomy in more severe biliary disease.

Review Meta Analysis
Staple versus fibrin glue fixation in laparoscopic total extraperitoneal repair of inguinal hernia: a systematic review and meta-analysis.
Fixation of mesh is typically performed to minimize risk of recurrence in laparoscopic inguinal hernia repair. Mesh fixation with staples has been implicated as a cause of chronic inguinal pain. Our study aim is to compare mesh fixation using a fibrin sealant versus staple fixation in laparoscopic inguinal hernia and compare outcomes for hernia recurrence and chronic inguinal pain. ⋯ The meta-analysis does not show an advantage of staple fixation of mesh over fibrin glue fixation in laparoscopic total extraperitoneal inguinal hernia repair. Because fibrin glue mesh fixation with laparoscopic inguinal hernia repair achieves similar hernia recurrence rates compared with staple/tack fixation, but decreased incidence of chronic inguinal pain, it may be the preferred technique.

Randomized Controlled Trial
Testicular functions, chronic groin pain, and quality of life after laparoscopic and open mesh repair of inguinal hernia: a prospective randomized controlled trial.
Laparoscopic inguinal hernia repair is still not the gold standard for patients with inguinal hernia. The aim of this study was to compare testicular dysfunction, incidence and factors influencing chronic groin pain, and quality of life after laparoscopic and open mesh repair. ⋯ Laparoscopic repair seems favorable in terms of better preservation of testicular functions, lower incidence of acute and chronic groin pain, and significant improvement in quality of life when compared to open repair. Younger age, preoperative pain, pain after 1 week postoperatively, and open mesh repair were found to be significant risk factors for chronic groin pain.

Whether bilateral total extraperitoneal (TEP) inguinal hernia repair is associated with worse outcomes than unilateral TEP continues to be a matter of debate. This study aimed to compare different outcomes of large cohorts of patients undergoing bilateral versus unilateral TEP. ⋯ This is the first population-based analysis in the literature to compare different outcomes in a prospective cohort of more than 6,500 patients undergoing bilateral versus unilateral TEP. Although the rates for intraoperative and surgical postoperative complications were slightly higher for the patients undergoing bilateral TEP repair, the absolute differences were small and of minor clinical relevance. Bilateral TEP repair is associated with a minimal increase in operating time and similar LOS, general postoperative complications, and conversion rates. Therefore, for patients with bilateral inguinal hernia, a simultaneous endoscopic approach represents an excellent therapeutic option.
