Choledocholithiasis is present in up to 15% of cholecystectomy patients. Treatment can be surgical, endoscopic, or via interventional radiology. We hypothesized significant heterogeneity between hospitals exists in the approach to suspected common duct stones.A retrospective review of patients that had a preoperative MRCP, endoscopic ultrasound, endoscopic retrograde cholangiopancreatogram (ERCP), or intra-operative cholangiogram was performed. Comparisons were by Wilcoxon-Mann-Whitney tests with significance of p 0.05 for paired variables and p 0.017 for multiple comparisons.Twelve participating institutions identified 1263 patients (409 men and 854 women) with a median age of 49 years (IQR: 31-94). Liver function tests (LFT's) were elevated in 939 patients (75%), median bilirubin level 1.75 mg/dl (IQ: 0.8-3.7 mg/dl) and median common duct size 7 mm (IQR 5-10 mm). The most common initial procedure was cholecystectomy with IOC at seven institutions, endoscopy at four and MRCP at one.Significant variation exists within the surgical community regarding suspected common duct stones. These results underscore the need for a protocol for common duct stones to minimize multiple, redundant interventions.

BACKGROUND Historically, hemorrhage has been attributed as the leading cause (40%) of early death. However, a rigorous, real-time classification of the cause of death (COD) has not been performed. This study sought to prospectively adjudicate and classify COD to determine the epidemiology of trauma mortality. METHODS Eighteen trauma centers prospectively enrolled all adult trauma patients at the time of death during December 2015 to August 2017. Immediately following death, attending providers adjudicated the primary and contributing secondary COD using standardized definitions. Data were confirmed by autopsies, if performed. RESULTS One thousand five hundred thirty-six patients were enrolled with a median age of 55 years (interquartile range, 32-75 years), 74.5% were male. Penetrating mechanism (n = 412) patients were younger (32 vs. 64, p < 0.0001) and more likely to be male (86.7% vs. 69.9%, p < 0.0001). Falls were the most common mechanism of injury (26.6%), with gunshot wounds second (24.3%). The most common overall primary COD was traumatic brain injury (TBI) (45%), followed by exsanguination (23%). Traumatic brain injury was nonsurvivable in 82.2% of cases. Blunt patients were more likely to have TBI (47.8% vs. 37.4%, p < 0.0001) and penetrating patients exsanguination (51.7% vs. 12.5%, p < 0.0001) as the primary COD. Exsanguination was the predominant prehospital (44.7%) and early COD (39.1%) with TBI as the most common later. Penetrating mechanism patients died earlier with 80.1% on day 0 (vs. 38.5%, p < 0.0001). Most deaths were deemed disease-related (69.3%), rather than by limitation of further aggressive care (30.7%). Hemorrhage was a contributing cause to 38.8% of deaths that occurred due to withdrawal of care. CONCLUSION Exsanguination remains the predominant early primary COD with TBI accounting for most deaths at later time points. Timing and primary COD vary significantly by mechanism. Contemporaneous adjudication of COD is essential to elucidate the true understanding of patient outcome, center performance, and future research. LEVEL OF EVIDENCE Epidemiologic, level II.

Introduction Over the last 5 years, the American Association for the Surgery of Trauma has developed grading scales for emergency general surgery (EGS) diseases. In a previous validation study using diverticulitis, the grading scales were predictive of complications and length of stay. As EGS encompasses diverse diseases, the purpose of this study was to validate the grading scale concept against a different disease process with a higher associated mortality. We hypothesized that the grading scale would be predictive of complications, length of stay, and mortality in skin and soft-tissue infections (STIs). Methods This multi-institutional trial encompassed 12 centers. Data collected included demographic variables, disease characteristics, and outcomes such as mortality, overall complications, and hospital and ICU length of stay. The EGS scale for STI was used to grade each infection and two surgeons graded each case to evaluate inter-rater reliability. Results 1170 patients were included in this study. Inter-rater reliability was moderate (kappa coefficient 0.472-0.642, with 64-76% agreement). Higher grades (IV and V) corresponded to significantly higher Laboratory Risk Indicator for Necrotizing Fasciitis scores when compared with lower EGS grades. Patients with grade IV and V STI had significantly increased odds of all complications, as well as ICU and overall length of stay. These associations remained significant in logistic regression controlling for age, gender, comorbidities, mental status, and hospital-level volume. Grade V disease was significantly associated with mortality as well. Conclusion This validation effort demonstrates that grade IV and V STI are significantly predictive of complications, hospital length of stay, and mortality. Though predictive ability does not improve linearly with STI grade, this is consistent with the clinical disease process in which lower grades represent cellulitis and abscess and higher grades are invasive infections. This second validation study confirms the EGS grading scale as predictive, and easily used, in disparate disease processes.

Background The objective of this multi-center study was to examine the follow-up trends after emergency department (ED) discharge in a large and socioeconomically diverse patient population. Methods We performed a 3-year retrospective analysis of adult patients with acutely symptomatic hernias who were discharged from the EDs of five geographically diverse hospitals. Results Of 674 patients, 288 (43%) were evaluated in the clinic after discharge from the ED and 253 (37%) underwent repair. Follow-up was highest among those with insurance. A total of 119 patients (18%) returned to the ED for hernia-related complaints, of which 25 (21%) underwent urgent intervention. Conclusion The plan of care for patients with acutely symptomatic hernias discharged from the ED depends on outpatient follow-up, but more than 50% of patients are lost to follow-up, and nearly 1 in 5 return to the ED. The uninsured are at particularly high risk.
