A call for a standardized definition of perforated appendicitis.

BACKGROUND Abscess rates have been reported to be as low as 1% and as high as 50% following perforated appendicitis (PA). This range may be because of lack of universal definition for PA. An evidence-based definition (EBD) is crucial for accurate wound classification, risk-stratification, and subsequent process optimization. ACS NSQIP-Pediatric guidelines do not specify a definition of PA. We hypothesize that reported postoperative abscess rates underrepresent true incidence, as they may include low-risk cases in final calculations. METHODS Local institutional records of PA patients were reviewed to calculate the postoperative abscess rate. The ACS NSQIP-Pediatric participant use file (PUF) was used to determine cross-institutional postoperative abscess rates. A PubMed literature review was performed to identify trials reporting PA abscess rates, and definitions and rates were recorded. RESULTS 20.9% of our patients with PA developed a postoperative abscess. The ACS NSQIP-Pediatric abscess rate was significantly lower (7.61%, p<0.001). In the eighteen published studies analyzed, average abscess rate (14.49%) was significantly higher than ACS NSQIP-Pediatric (p<0.001). There was significantly more variation in trials that do not employ an EBD of perforation (Levenes test F-value =6.980, p=0.018). CONCLUSIONS A standard EBD of perforation leads to lower variability in reported postoperative abscess rates following PA. Nonstandard definitions may be significantly altering the aggregate rate of postoperative abscess formation. We advocate for adoption of a standard definition by all institutions participating in ACS NSQIP-Pediatric data submission. LEVEL OF EVIDENCE III.

Evolution in management of adolescent blunt aortic injuries—a single institution 22-y experience

BACKGROUND In children, severe, life-threatening traumatic injuries of the thoracic aorta can be seen after motor vehicle collisions (MVCs) resulting in a sudden deceleration. Concurrent injuries in the thorax and abdomen can make treatment prioritization difficult and require early recognition and prompt intervention. With the increased utilization of minimally invasive endovascular approaches to traumatic aortic (TA) injuries, patients are often spared the increased surgical morbidity (spinal cord ischemia and renal insults) that can be seen with an open technique. The aim of this study was to evaluate a single American College of Surgeons level 1 pediatric trauma centers 22-y experience with TA injuries in children. METHODS After the Institutional Review Board approval, a 22-y (January 1990-April 2013) retrospective review of all pediatric trauma patients admitted with TA injuries was performed. Patient demographics including age, injury detail, treatment, and outcomes were recorded for analysis. RESULTS 17 children (<21-y old) were identified with ages ranging from 13-20 y old. The most common mechanism of injury was MVC with all 17 children sustaining TA injuries. The traumatic injuries included aortic transection (9), intimal flap (5), pseudoaneurysm (2), and contained thoracic rupture (1). All children were managed operatively with those before 2008 using an open technique. The endovascular approach was used in 7/17 (41%) cases with the median length of hospitalization 12 d versus 22.5 d using the open approach (P < 0.05). No child required conversion from an endovascular to an open technique for treatment of the aortic injury. There were no operative deaths, no procedure-related paraplegia and all children were discharged home from the hospital. Two children had mild mental deficits as a result of head trauma. CONCLUSIONS TA injuries are an uncommon injury in children and can result from MVCs or other sudden deceleration mechanisms. Surgical intervention is required in most of the cases and can be performed safely and effectively with low morbidity using an endovascular approach, which is the evolving approach of choice for thoracic aortic injuries. Lengthy follow-up care is recommended in children treated with an endovascular device to monitor for endoleaks and device complications.

Clinically Competent and Fiscally at Risk: Impact of Debt and Financial Parameters on the Surgical Resident

BACKGROUND While the costs of medical training continue to increase, surgeon income and personal financial decisions may be challenged to manage this expanding debt burden. We sought to characterize the financial liability, assets, income, and debt of surgical residents, and evaluate the necessity for additional financial training. STUDY DESIGN All surgical trainees at a single academic center completed a detailed survey. Questions focused on issues related to debt, equity, cash flow, financial education, and fiscal parameters. Responses were used to calculate debt-to-asset and debt-to-income ratios. Predictors of moderate risk debt-to-asset ratio (0.5 to 0.9), high risk debt-to-asset ratio (≥0.9), and high risk debt-to-income ratio (>0.4) were evaluated. All analyses were performed in SPSS v.21. RESULTS One hundred five trainees completed the survey (80% response rate), with 38% of respondents reporting greater than

200,000 in educational debt. Overall, 82% of respondents had a moderate or high risk debt-to-asset ratio. Residency program, year, sex, and perception of financial knowledge did not correlate with high risk debt-to-asset ratio. Residents with high debt-to-asset ratios were more likely to have a high level of concern about debt (52% vs 0%, p < 0.001) when compared with residents who had low debt-to-asset ratios. The majority (79%) of respondents felt strongly that inclusion of additional financial training in residency education is a critical need. CONCLUSIONS In a climate of increasingly delayed financial gratification, surgical trainees are on critically unstable financial footing. There is a major gap in current surgical education that requires reassessment for the long-term financial health of residents.

Filling the void: a low-cost, high-yield approach to addressing incidental findings in trauma patients

INTRODUCTION Contrast-enhanced CT remains the first-line imaging for evaluating postoperative abscess (POA) after appendicitis. Given concerns of ionizing radiation use in children, we began utilizing quick MRI to evaluate POA and summarize our findings in this study. MATERIALS AND METHODS Children imaged with quick MRI from 2015 to 2017 were compared to children evaluated with CT from 2012 to 2014 using an age and weight matched case-control model. Radiation exposure, size and number of abscesses, length of exam, drain placement, and patient outcomes were compared. RESULTS There was no difference in age or weight (p>0.60) between children evaluated with quick MRI (n=16) and CT (n=16). Mean imaging time was longer (18.2±8.5min) for MRI (p<0.001), but there was no difference in time from imaging order to drain placement (p=0.969). No children required sedation or had non-diagnostic imaging. There were no differences in abscess volume (p=0.346) or drain placement (p=0.332). Thirty-day follow-up showed no difference in readmissions (p=0.551) and no missed abscesses. Quick MRI reduced imaging charges to

CONCLUSION Quick MRI demonstrated equivalent outcomes to CT in terms of POA detection, drain placement, and 30-day complications suggesting that MRI provides an equally effective, less expensive, and non-radiation modality for the identification of POA.

Health Care Resource Use in Laparoscopic and Open Inguinal Hernia Repair

Background. Incidental findings are prevalent in imaging but often go unreported to patients. Such unreported findings may present the potential for harm as well as medico‐legal ramifications. Methods. A chart review of trauma patients was undertaken over a year. Systems‐based changes were made utilizing our electronic medical record system and our staff protocols to improve the disclosure of clinically relevant incidental findings to patients. Results. During the preintervention period, 674 charts were reviewed. Trauma patients had a rate of incidental findings of 70%, and 36% of patients had clinically relevant incidentals. Rates of follow‐up recommendation and disclosure to patients were 22% and 27%, respectively. In the postintervention period, of the 648 charts were reviewed, the rates of a clinically relevant incidental finding were 35%, but the rates of follow‐up recommendation and disclosure to patients were 68% and 85%, respectively. Conclusion. Incidental findings are more prevalent herein than previously reported. With simple changes and minimal resources, clinically relevant and important improvement in reporting incidental findings can be made to mitigate the harm and medico‐legal impact of an incidental finding going unreported.
