To summarize our experience with small-bowel obstructions after laparoscopic Roux-en-Y gastric bypass. ⋯ Altered gastrointestinal tract anatomy results in vague symptoms and a poor yield with imaging studies. A sound knowledge of altered anatomy is the key to correct interpretation of imaging studies and prompt diagnosis.

Bariatric surgery for Medicare patients must be performed in an accredited hospital that performs at least 125 cases per year. We assessed the validity of this volume threshold and its policy implications. ⋯ When the results of statistical analysis are used for policy determination, the consequences for patient care may be substantial. Most studies of volume-outcome relationships rely on statistical methods that tend to amplify the effects and few fully characterize their statistical models. Despite the weak evidence for a volume-outcome relationship for bariatric surgery, a 125-case per year threshold has been set for center-of-excellence status, which eliminates most hospitals currently providing these services and disproportionately restricts access for the poor and underinsured.

Volume criteria are poor predictors of inpatient mortality after esophagectomy. Because many factors influence mortality for complex procedures, this study was designed to quantify such factors and analyze the volume-outcome relationship for esophagectomy. ⋯ Patient factors have a greater influence on inpatient mortality than case volume does. Although there is generally an inverse relationship between case volume and mortality, there is wide scatter between individual surgeons and hospitals, with a complex volume-outcome relationship. Using volume criteria alone to choose a provider may in some instances increase the risk of mortality.

Increasing rates of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections have also affected the microbial profile of breast abscesses. ⋯ Staphylococcus aureus is the most common pathogenic organism in modern breast abscesses. Many breast abscesses have community-acquired MRSA, with more than 50% of all S aureus and 19% of all cultures being MRSA. This finding parallels the local and national increases in MRSA reported in other soft-tissue infections. With increasing bacterial resistance and more minimally invasive management of breast abscesses, understanding the current bacteriologic profile of these abscesses is essential to determining the correct empirical antibiotic drug therapy.

Comparative Study
Mortality in adolescent girls vs boys following traumatic shock: an analysis of the National Pediatric Trauma Registry.
Female sex imparts a survival benefit after traumatic injury in children. ⋯ Adolescent girls exhibit lower mortality than boys following traumatic shock. This effect is not seen in prepubescent children. These findings suggest that hormonal differences may play a role in the sex-based outcome disparities following traumatic shock in children.
