The incidence of, and factors associated with, lymph node metastasis (LN+) in non-functional gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) are not well characterized. ⋯ This developed risk-score model, including both patient and tumor variables, can be used to calculate the risk for LN metastases in patients with GEP NETs.

Patients undergoing emergency general surgery (EGS) and interhospital transfer (IHT) have increased mortality. Prior analyses of IHT have been limited by the inability to track post-discharge outcomes or have not included nonoperative EGS. We evaluated outcomes for IHT to our tertiary care facility compared with direct admission through the emergency department. ⋯ After PSM to reduce confounding variables, patients with common EGS diagnoses transferred to a tertiary care facility have increased inpatient morbidity and mortality. The increased morbidity and resource utilization for these patients extends beyond the index hospital stay.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) achieves temporary hemorrhage control via aortic occlusion. Existing REBOA literature focuses on blunt trauma without a clearly defined role in penetrating trauma. This study compared clinical/injury data and outcomes after REBOA in penetrating vs blunt trauma. ⋯ Despite lower injury severity, REBOA was significantly less likely to improve or stabilize hemodynamics after penetrating trauma. Among patients arriving alive, however, outcomes were comparable, suggesting that penetrating REBOA may be most beneficial among patients with vital signs. Because hemorrhage source, catheter insertion setting, and deployment zone varied significantly between groups, existing blunt REBOA data may not be appropriately extrapolated to penetrating trauma. Further study of REBOA as a means of aortic occlusion in penetrating trauma is needed.

Bariatric surgery induces changes in gut microbiota that have been suggested to contribute to weight loss and metabolic improvement. However, whether preoperative gut microbiota composition could predict response to bariatric surgery has not yet been elucidated. ⋯ Preoperative gut microbiota could have an impact on bariatric surgery outcomes. Prevotella-to-Bacteroides ratio could be used as a predictive tool for weight loss trajectory. Early after surgery, patients who experienced successful weight loss showed an enrichment in taxa related to beneficial effects on host metabolism.

A biologic, degradable extracellular matrix (ECM) has been shown to support esophageal tissue remodeling, which could reduce the risk of anastomotic leak following total gastrectomy and esophagectomy. We evaluated the safety and efficacy of reinforcing the anastomosis with ECM in reducing anastomotic leak as compared to a matched cohort. ⋯ Esophageal anastomotic reinforcement after total gastrectomy or esophagectomy with a biologic, degradable ECM was mostly feasible and safe, but was not associated with a statistically significant decrease in anastomotic leak.
