Randomized Controlled Trial
Duration of Antimicrobial Prophylaxis in Patients Undergoing Major Hepatectomy With Extrahepatic Bile Duct Resection: A Randomized Controlled Trial.
To evaluate the optimal duration of antimicrobial prophylaxis in patients undergoing "complicated"' major hepatectomy with extrahepatic bile duct resection. ⋯ Two-day administration of antimicrobial prophylaxis is sufficient for patients undergoing hepatectomy with extrahepatic bile duct resection [Registration number: ID 000009800 (University Hospital Medical Information Network, http://www.umin.ac.jp)].

The optimal extent of groin completion lymph node dissection (CLND) (inguinal or ilioinguinal dissection) in patients with melanoma is controversial. The aim of this study was to evaluate whether the extent of groin CLND after a positive sentinel node biopsy (SNB) is associated with improved outcome. ⋯ There was no significant difference in recurrence pattern and survival rates between patients undergoing inguinal or ilioinguinal dissection after a positive SNB, even after stratification for a positive CLND result. An inguinal dissection is a safe first approach as CLND in patients with a positive SNB.

Randomized Controlled Trial Comparative Study
Comparative Study of Cortical Bone Trajectory-Pedicle Screw (Cortical Screw) versus Conventional Pedicle Screw in Single-Level Posterior Lumbar Interbody Fusion: A 2-Year Post Hoc Analysis from Prospectively Randomized Data.
The aim of this study was to report 2-year follow-up outcomes of posterior lumbar interbody fusion (PLIF) with cortical bone trajectory-pedicle screw (CS), in terms of fusion rates, clinical outcomes, surgical outcomes, and complications, and to compare these outcomes with outcomes for PLIF with conventional pedicle screw (PS). ⋯ We suggest that CS in single-level PLIF may be an alternative to PS.

Carolinas Comfort Scale as a Measure of Hernia Repair Quality of Life: A Reappraisal Utilizing 3788 International Patients.
The goal of the present study was to reaffirm the psychometric properties of the CCS using an expansive, multinational cohort. ⋯ The present study confirms that the CCS questionnaire is a validated, sensitive, and robust instrument for assessing QOL after hernia repair, which has become a predominant outcome measure in this discipline of surgery.

Hospital and Intensive Care Unit Length of Stay for Injury Admissions: A Pan-Canadian Cohort Study.
To assess the variation in hospital and intensive care unit (ICU) length of stay (LOS) for injury admissions across Canadian provinces and to evaluate the relative contribution of patient case mix and treatment-related factors (intensity of care, complications, and discharge delays) to explaining observed variations. ⋯ We observed significant variation in risk-adjusted hospital and ICU LOS across trauma systems in Canada. Provider ranks on hospital LOS were not related to those observed for ICU LOS. Treatment-related factors explained more interhospital variation in LOS than patient case-mix. Results suggest that interventions targeting reductions in low-value procedures, prevention of adverse events, and better discharge planning may be most effective for optimizing LOS for injury admissions.
