Review Meta Analysis
An institutional analysis and systematic review with meta-analysis of pneumatic versus hydrostatic reduction for pediatric intussusception.
Intussusception remains a frequent cause of bowel obstruction in children and typically is treated by reduction via enema. Controversy persists regarding the optimal reduction technique to maximize success while minimizing morbidity. ⋯ Pneumatic reduction is more likely to successfully reduce intussusception in children without evidence of increased morbidity. In the context of available expertise, pneumatic reduction should be the method of choice for the treatment of intussusception barring an indication for immediate operative intervention.

In a previous study, we demonstrated that swine with metabolic syndrome treated with alcohol had improved insulin signaling. We developed a follow-up study to evaluate the effects of alcohol on ischemic myocardium in animals without metabolic syndrome. ⋯ Despite similar serum glucose and insulin levels, alcohol consumption up-regulates the insulin signaling pathway in the absence of metabolic syndrome in both nonischemic and chronically ischemic myocardium. These results suggest that alcohol selectively up-regulates the insulin signaling pathway despite normoglycemia.

We have demonstrated previously that suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, improves survival in a lipopolysaccharide-induced lethal model of endotoxemia. The goal of this study was to investigate the impact of SAHA on survival in a more clinically relevant model of cecal ligation and puncture (CLP)-induced septic shock and to elucidate changes in cytokine responses and organ injury. ⋯ SAHA treatment improves survival, decreases "cytokine storm," and prevents distant organ damage in a lethal septic model.

Laparoscopic repair of paraesophageal hernia (PEH) has been shown to result in excellent relief of symptoms and improved quality of life (QOL) despite a high radiographically identified recurrence rate. Because there is no uniform definition of PEH recurrence, it is difficult to compare studies reporting on this. This study attempts to introduce consistency to the definition of PEH recurrence based on correlation of symptoms and radiographic findings. ⋯ Our analysis of symptom scores after laparoscopic PEH repair suggests that significant worsening occurs with RRH > 2 cm. Given that there is no consistent description of recurrent PEH, we suggest this as a possible standardized definition. Overall, patients with recurrent PEHs continue to experience excellent QOL and rarely require reoperation.

Comparative Study
Provider versus patient factors impacting hospital length of stay after pancreaticoduodenectomy.
Studies reporting perioperative outcomes after pancreaticoduodenectomy (PD) have focused on morbidity and mortality. Understanding factors that impact hospital duration of stay may have cost-saving implications. We sought to examine variation in duration of stay after PD occurring at the patient, surgeon, and hospital levels. ⋯ PD patients treated by higher volume surgeons and at higher volume hospitals had a shorter duration of stay. Although some patient-level factors impact duration of stay after PD, nonclinical factors such as surgeon and hospital volume were also important contributors to duration of stay.
