Comparative Study
Addition of direct peritoneal lavage to human cadaver organ donor resuscitation improves organ procurement.
Brain dead organ donors have altered central hemodynamic performance, impaired hormone physiology, exaggerated systemic inflammatory response, end-organ microcirculatory dysfunction, and tissue hypoxia. A new treatment, direct peritoneal resuscitation (DPR), stabilizes vital organ blood flow after conventionally resuscitated shock to improve these derangements. ⋯ Direct peritoneal resuscitation reduced IV fluid requirement and IV pressor use as well as increased hepatic blood flow and organs transplanted per donor. Direct peritoneal resuscitation studies show it to be a safe, effective method to augment organ donor resuscitation and additional large-scale trials should be conducted to validate these findings.

We recently developed and validated a prognostic model that accurately predicts the 2-year risk of emergent gallstone-related hospitalization in older patients presenting with symptomatic gallstones. ⋯ The risk of recurrent acute biliary symptoms requiring hospitalization has no influence, or even a paradoxical negative influence, on the decision to perform elective cholecystectomy after an initial symptomatic episode. Translation of the risk prediction model into clinical practice can better align treatment with risk and improve outcomes in older patients with symptomatic gallstones.

Acute care surgery: defining mortality in emergency general surgery in the state of Maryland.
Emergency general surgery (EGS) is a major component of acute care surgery, however, limited data exist on mortality with respect to trauma center (TC) designation. We hypothesized that mortality would be lower for EGS patients treated at a TC vs non-TC (NTC). ⋯ Emergency general surgery patients treated at TCs had lower mortality for moderate APR_SOI, but increased mortality for extreme APR_SOI when compared with NTCs. Additional investigation is required to better evaluate this unexpected finding.

Minimally invasive esophagectomy (MIE) is increasingly being used to treat patients with cancer of the esophagus and gastroesophageal junction. We previously reported that oncologic efficacy may be improved with MIE compared with open or hybrid esophagectomy (OHE). We compared survival of patients undergoing MIE and OHE. ⋯ This study supports MIE for EC as a superior procedure with respect to overall survival, perioperative mortality, and severity of postoperative complications. Several biases may have affected these results: earlier stage in the MIE group and disparity in timing of the procedures. These results will need to be confirmed in future prospective studies with longer follow-up.

Our group recently published a clinical pathway (Le Bonheur Clinical Pathway [LeB-P]) that used the Samuel Pediatric Appendicitis Score with selective use of ultrasonography (USG) for diagnosis of children at risk for appendicitis. The objective of this study was to model the cost-effectiveness of implementing the LeB-P compared with usual care. ⋯ Although performing USG on all children with suspected appendicitis was determined to be the most cost-effective strategy, using the Pediatric Appendicitis Score with selective use of USG (LeB-P) improved diagnostic accuracy at a moderate increase in cost and decreased CT use.
