Comparative Study
Use and dissemination of the brisbane 2000 nomenclature of liver anatomy and resections.
The Brisbane 2000 Nomenclature of Hepatic Anatomy and Resections was created to standardize terminology in an area, which previously was characterized by redundant and confusing terms. The purpose of this study was to evaluate the use and dissemination of the nomenclature 10 years after its introduction. ⋯ The Brisbane terminology is being adopted worldwide but its adoption is still incomplete.

Comparative Study
Risk of gastric pouch enlargement with adjustable gastric banding in premenopausal women: sex hormones may play a role.
To examine the influence of age and gender on the development of proximal gastric pouch distension (PPD) after laparoscopic adjustable gastric banding (LAGB) surgery. ⋯ Younger women are at higher risk of PPD after LAGB surgery than men and women older than 50 years. Sex hormones may play a role in predisposing to gastric stretch after surgery. These findings may apply more broadly to the gastric "restrictive" component of other bariatric procedures.

To determine whether remnant pancreatic volume (RPV), subcutaneous/visceral adipose tissue(SAT/VAT) area, and skeletal muscle (SM) area calculated from preoperative computed tomography (CT) can predict the occurrence of pancreatic anastomotic failure (PAF) after pancreatoduodenectomy (PD). ⋯ Our 2-predictor model using VAT area and SM area based on volumetric quantification using preoperative CT may offer clinical benefit as an objective prognostic measure to predict clinically relevant PAF after PD.

Comparative Study
LINE-1 hypomethylation is associated with a poor prognosis among patients with curatively resected esophageal squamous cell carcinoma.
To investigate the relationship between the long interspersed nucleotide element-1 (L1/LINE-1) methylation level and the disease-free survival and cancer-specific survival in patients with esophageal squamous cell carcinoma (ESCC). ⋯ LINE-1 hypomethylation in ESCC is associated with a shorter survival, thus suggesting that it has potential for use as a prognostic biomarker.

Comparative Study
Scheduled surgery admissions and occupancy at a children's hospital: variation we can control to improve efficiency and value in health care delivery.
Describe variability in admission, discharge, and occupancy patterns for surgical patients at a large children's hospital and assess the relationship between scheduled admissions and occupancy. ⋯ Scheduled admissions contribute significantly to variability in occupancy. Predictable patterns of admissions lead to high occupancy on some days and unused capacity on others, with few days being at an optimal level of occupancy. These predictable patterns suggest opportunities to improve hospital operations with changes in scheduled admission patterns, which present a different problem than random demand.
