Randomized Controlled Trial Multicenter Study Comparative Study
Single-incision laparoscopic cholecystectomy is associated with improved cosmesis scoring at the cost of significantly higher hernia rates: 1-year results of a prospective randomized, multicenter, single-blinded trial of traditional multiport laparoscopic cholecystectomy vs single-incision laparoscopic cholecystectomy.
Minimally invasive techniques have become an integral part of general surgery with recent investigation into single-incision laparoscopic cholecystectomy (SILC). This study presents the final 1-year results of a prospective, randomized, multicenter, single-blinded trial of SILC vs multiport cholecystectomy (4PLC). ⋯ Results of this trial show SILC to be a safe and feasible procedure when compared with 4PLC, with similar total adverse events but with an identified significant increase in hernia formation. Cosmesis scoring and patient preference at 12 months continue to favor SILC, and more than half of the patients were willing to pay more for a single-site surgery over a standard laparoscopic procedure. Additional longer-term population-based studies are needed to clarify if this increased rate of hernia formation as compared with 4PLC will continue to hold true.

Virtual reality robotic surgery warm-up improves task performance in a dry laboratory environment: a prospective randomized controlled study.
Preoperative simulation warm-up has been shown to improve performance and reduce errors in novice and experienced surgeons, yet existing studies have only investigated conventional laparoscopy. We hypothesized that a brief virtual reality (VR) robotic warm-up would enhance robotic task performance and reduce errors. ⋯ We observed significant performance improvement and error reduction rates among surgeons of varying experience after VR warm-up for basic robotic surgery tasks. In addition, the VR warm-up reduced errors on a more complex task (robotic suturing), suggesting the generalizability of the warm-up.

Validation of rules to predict emergent surgical intervention in pediatric trauma patients.
Trauma centers use guidelines to determine when a trauma surgeon is needed in the emergency department (ED) on patient arrival. A decision rule from Loma Linda University identified patients with penetrating injury and tachycardia as requiring emergent surgical intervention. Our goal was to validate this rule and to compare it with the American College of Surgeons' Major Resuscitation Criteria (MRC). ⋯ Emergent surgical intervention is rare in the pediatric trauma population. Although precision of predictive accuracies of the Loma Linda Rule and MRC were limited by small numbers of outcomes, neither set of criteria appears to be sufficiently accurate to recommend their routine use.

A risk model to predict 90-day mortality among patients undergoing hepatic resection.
Reliable criteria to predict mortality after hepatectomy remain poorly defined. We sought to identify factors associated with 90-day mortality, as well as validate the "50-50" and peak bilirubin of >7 mg/dL prediction rules for mortality after liver resection. In addition, we propose a novel integer-based score for 90-day mortality using a large cohort of patients. ⋯ The 50-50 and bilirubin >7-mg/dL rules were not accurate in predicting 90-day mortality. Rather, a composite integer-based risk score based on postoperative day 3 international normalized ratio, bilirubin, creatinine, and complication grade more accurately predicted 90-day mortality after hepatectomy.

Randomized Controlled Trial Multicenter Study Comparative Study
Are results of bariatric surgery different in the Middle East? Early experience of an international bariatric surgery program and an ACS NSQIP outcomes comparison.
Bariatric operations performed at the Bariatric and Metabolic Institute Abu Dhabi are submitted randomly from the entire surgery volume at Sheikh Khalifa Medical City to the American College of Surgeons (ACS) NSQIP. Our aim is to report our early experience and compare our bariatric surgery outcomes with ACS NSQIP hospitals of similar size. ⋯ This is the first report comparing outcomes of an international bariatric surgery program (Bariatric and Metabolic Institute Abu Dhabi) with ACS NSQIP bariatric surgery programs. Our outcomes are equivalent to ACS NSQIP bariatric surgery programs.
