Bridging the Gap: Comparison of Outpatient Clinic and Emergency Department Patients Undergoing Cholecystectomy.

INTRODUCTION: Literature shows failure of the outpatient clinic (OC) pathway after emergency department (ED) ultrasound diagnosis of symptomatic cholelithiasis (SC). We hypothesized SC to be more prevalent on final surgical pathology (FSP) in patients who successfully completed OC pathway. METHODS: This retrospective single-institution chart review compared OC and ED patients with right upper quadrant (RUQ) pain and cholelithiasis whom underwent cholecystectomy. Clinical evaluation was considered positive if RUQ pain >4 h, or + Murphy's sign. Ultrasound was positive if two of these three were present: sonographic Murphy's, wall thickness > 4 mm, or pericholecystic fluid. Results were compared with FSP. RESULTS: Six hundred-seven patients underwent cholecystectomy, 299 OC and 308 ED. OC was more likely to SC (23% versus 4.6%) (P < 0.0001) and ED acute cholecystitis (39.3% versus 4.7%). Chronic cholecystitis was the most common FSP in both OC (72%) and ED (56%) populations, of these, 73% of OC denied pain >4 h versus only 10% of ED (P < 0.001). Median time from evaluation to cholecystectomy was 14 d versus 14 h in the OC and ED respectively (P < 0.0001). CONCLUSIONS: While chronic cholecystitis was the most common FSP in both OC and ED, the majority of OC reported RUQ pain <4 h delineating these presentations. Duration of pain should be utilized as algorithm triage. We recommend patients with pain episode <4 h should complete OC algorithm with expedited cholecystectomy within 14 d.

Perforated Appendicitis in Children: Management, Microbiology, and Antibiotic Stewardship.

Although appendicitis has been described for more than 300 years, its optimal management remains a topic of active investigation. Acute appendicitis is the most common cause of peritonitis in children, and rates of perforated appendicitis are much higher in children than in adults. Increased risk for perforated appendicitis in children is related to a delay in diagnosis due to age, size, access to care, and more. Surgical options include immediate appendectomy versus nonoperative management with intravenous antibiotics ± a drainage procedure, with a subsequent interval appendectomy. Microbiota of perforated appendicitis in children most often includes Escherichia coli, Bacteroides fragilis, Streptococcus, and more. Even though the most common organisms are known, there is a large variety of practice when it comes to postoperative antibiotic management in these patients. Studies discuss the benefits of mono- versus dual or triple therapy without a particular consensus regarding what to use. This is reflected across differing practices at various institutions. In this review, we aim to explore the implications of perforated appendicitis in pediatrics, common organisms seen, antibiotic regimen coverage, and the implications of variations of practice. Resistance to commonly used broad-spectrum antibiotics is evolving, therefore minimization of care variability is needed for improved patient outcomes and proper antibiotic stewardship.

Despite Recovery from Necrotizing Enterocolitis Infants Retain a Hyperinflammatory Response to Injury.

Background: Necrotizing enterocolitis (NEC) is the leading gastrointestinal cause of death of premature neonates. NEC is associated with prematurity, a hyperinflammatory response, and dysregulation of intestinal barrier function. We hypothesize that patients with NEC will have, and continue to have after recovery, an increased hyperinflammatory intestinal response compared to those patients without NEC. Methods: Neonates with NEC, those that have recovered from NEC, and those without NEC undergoing intestinal resections had specimens collected and snap frozen or generated into enteroids. The enteroids were treated with 100ug/mL lipopolysaccharide (LPS) and subjected to 24 hr of hypoxia together, then compared with untreated controls. Expression of Tumor Necrosis Factor (TNF-α) and interleukin 8 (IL-8) were evaluated via RT-qPCR and ELISA to measure inflammatory response. ANOVA determined statistical significance (p<0.05). Results: There was no difference in inflammatory markers in recovered NEC tissue compared to non-NEC tissue on RTqPCR (p=0.701 TNF-α and 0.861 IL-8). However, recovered NEC enteroids demonstrate elevated levels of inflammatory markers after treatment compared to non-NEC enteroids after treatment on RTqPCR (p=0.0485 TNF-α, p=0.0057 IL-8) and ELISA (p=0.0354 TNF-α, p=0.0011 IL-8). Recovered NEC enteroids that underwent treatment demonstrated increased inflammatory markers compared to recovered NEC enteroids without treatment on RTqPCR (p=0.0045 TNF-α, p=0.0002 IL-8) and ELISA (p=0.034 TNF-α, p=0.0002 IL-8) suggesting a heightened inflammatory response to a second hit. Conclusion: Intestinal tissue resected from neonates with NEC has an elevated hyperinflammatory response compared to neonates recovered from NEC and neonates without NEC. Enteroids generated from patients that have recovered from NEC have a heightened inflammatory response in response to NEC inducing stimuli compared to controls. This tendency towards an increased hyperinflammatory state may be correlated with an infant's proclivity to develop NEC and demonstrates the significance of a second hit on this tissue creating a heightened inflammatory response. This could be correlated with the impact and trajectory of an illness post recovery from NEC.

Not all cholecystitis is created equal: Disparities contributing to ED presentation and failure of the outpatient algorithm.

BACKGROUND: The majority of final surgical pathology (FSP) from both emergency department (ED) and outpatient clinic (OC) patients is chronic cholecystitis. We aimed to differentiate these presentations and identify disparities associated with ED utilization and OC failure. METHODS: Retrospective chart review of single institution ED and OC cholecystectomies for cholelithiasis. Clinical presentation, FSP, demographics, and zip code poverty (ZCP) levels were evaluated. Data analysis by summary statistics, bivariate comparisons, and logistic regression. RESULTS: Of 299 OC and 308 ED patients, OC was more likely to be Caucasian (78% vs 46%, p < 0.0001) and insured (89% vs. 32%, p < 0.0001). 71.8% of OC with ZCP <10% had insurance versus only 32.5% in ZCP >20%. Uninsured ED OR was 13.1 (95% CI 8.7-22.9). CONCLUSION: Uninsured ED patients are vulnerable to fail the outpatient algorithm, especially when misdiagnosed by US. Clinical diagnosis of cholecystitis in this population should warrant offering of urgent cholecystectomy.

Anecdotes Drive Attitudes, Data Drives Decisions: Optimizing the Emergency Department Workup Prior to Surgical Consultations.

PURPOSE: Emergency department (ED) wait times and ED length of stay (LOS) have a significant impact on patient morbidity and mortality and patient satisfaction. Consultation-to-decision time can contribute to increased wait times and LOS in the ED. Up to 40% of patients presenting to the ED require consultation from subspecialty services. We hypothesize that in surgical patients, completion of workup prior to consultation will decrease consultation-to-decision time, ED wait times, and LOS in the ED. METHODS: A retrospective review was conducted at a single site including all overnight general surgery consultations from the ED over 2-months. Data collected included wait times, LOS, and workup completed prior to consultation. Summary statistics were calculated and bivariate tests were performed using t-tests for continuous variables. RESULTS: Time to final surgical plan and LOS in ED were evaluated for 137 patients comparing "complete" and "incomplete" workups at time of consultation. It was considered a "complete" workup if labs and imaging were resulted prior to time of consult. If any baseline tests were not ordered prior to time of consult, it was considered an "incomplete" workup. Analysis demonstrated an average time of 4.9 and 2.5 hours for consultation-to-decision time for "incomplete" and "complete" workups respectively (p < 0.0001). For LOS in ED, there was an average of 11.4 and 7.9 hours for "incomplete" and "complete" workups respectively (p < 0.0001). CONCLUSIONS: There is a significant difference in consultation-to-decision time and LOS in the ED when consultation is performed following a complete versus incomplete workup for surgical patients independent of inherent wait times for testing to result and the need for additional testing requested from consulting services. Developing strategies to optimize workups from the ED prior to surgical consultation, including the development of care pathways, could significantly decrease patient wait times and LOS in the ED.
