Knowledge of the independent risk factors for mortality in colon and rectal surgery can aid surgeons in surgical decision making and in providing patients with appropriate information about the risks of surgery. This study endeavors to identify the risk factors for mortality that are associated with colon and rectal surgery. ⋯ In patients undergoing colorectal surgery, emergent surgery, liver disease, total colectomy, age older than 65 years, chronic renal failure, and malignant tumor are the major risk factors for in-hospital mortality.

Effect of repetitive loading on the mechanical properties of biological scaffold materials.
Coughing, bending, and lifting raise the pressure inside the abdomen, repetitively increasing stresses on the abdominal wall and the associated scaffold. The purpose of this study was to evaluate the effect of repetitive loading on biological scaffolds. It was hypothesized that exposure to repetitive loading would result in decreased tensile strength and that crosslinked scaffolds would resist these effects more effectively than non-crosslinked scaffolds. ⋯ Materials that rapidly lose strength after repetitive loading might not be appropriate in clinical scenarios involving elevated stresses, such as in patients with high body mass index or when replacing large areas of the abdominal wall without tissue reinforcement, although scaffolds that maintain initial tensile strength can be particularly advantageous.

Comparative Study
Outcomes of endoscopic and percutaneous drainage of pancreatic fluid collections arising after pancreatic tail resection.
Up to 15% to 30% of patients develop pancreatic fluid collections (PFCs) after pancreatic tail resection. Percutaneous and endoscopic methods have been used to drain these collections, though few data are available that compare outcomes of these modalities. ⋯ Endoscopic drainage and percutaneous drainage appear to be equally effective and complementary interventions for PFCs occurring after pancreatic tail resection. Primary endoscopic drainage may be associated with shorter hospital stay and fewer CT scans.
