Randomized Controlled Trial
Effect of simvastatin on physiological and biological outcomes in patients undergoing esophagectomy: a randomized placebo-controlled trial.
To test whether simvastatin improves physiological and biological outcomes in patients undergoing esophagectomy. ⋯ In this proof of concept study, pretreatment with simvastatin in esophagectomy decreased biomarkers of inflammation as well as pulmonary epithelial and systemic endothelial injury.

Multicenter Study
A prospective policy development to increase split-liver transplantation for 2 adult recipients: results of a 12-year multicenter collaborative study.
To analyze in a multicenter study the potential benefit of a new prospective policy development to increase split-liver procedures for 2 adult recipients. ⋯ AASLT should be considered a surgical option for selected smaller-sized adults only in experimental clinical studies in experienced centers.

Randomized Controlled Trial
A prospective, randomized, noninferiority trial of steroid dosing after major colorectal surgery.
To evaluate the safety of perioperative low-dose steroids (LDS) versus high-dose steroids (HDS) in steroid-treated patients with inflammatory bowel disease (IBD) undergoing major colorectal surgery. ⋯ In IBD patients undergoing abdominal surgery, the incidence of postural hypotension or adrenal insufficiency is similar among those receiving high doses or low doses of corticosteroids in the perioperative period. To reduce complications associated with unnecessarily high doses of steroids, steroid-treated IBD patients undergoing major colorectal surgery should be treated with low doses of steroids in the perioperative period. (Clinicaltrials.gov ID# NCT01559675).

To determine the proportion of registered trials published in the surgical literature, to compare, in registered trials, the primary outcomes registered with those published and to determine whether outcome-reporting bias favored significant primary outcomes. ⋯ Less than half of all RCTs published in general surgical journals were adequately registered, and approximately 30% had discrepancies in the registered and published primary outcome with 90% of those assessable favoring a statistically positive result.

Comparative Study
Comparative operative outcomes of early and delayed cholecystectomy for acute cholecystitis: a population-based propensity score analysis.
To compare the operative outcomes of early and delayed cholecystectomy for acute cholecystitis. ⋯ These results support the benefit of early overdelayed cholecystectomy for patients with acute cholecystitis.
