Same-day discharge vs. observation after laparoscopic pediatric appendectomy: a prospective cohort study.

BACKGROUND: Through 2015, the practice at our university based free-standing children's hospital was to admit uncomplicated appendicitis patients for overnight observation post-operatively. Given the increasing body of evidence suggesting the safety and feasibility of same-day discharge after appendectomy for uncomplicated appendicitis, we elected to perform a prospective study evaluating the complication rates of same-day discharge compared to overnight observation at our institution, given our large volume of appendicitis. METHODS: Pediatric patients who underwent laparoscopic appendectomies for uncomplicated appendicitis in 2016 were analyzed. Data regarding demographics, admission, and discharge times and outcomes of complications, as well as readmissions, return to the emergency department, and nonscheduled clinic visits were collected and analyzing using chi-square and multivariate regression. Cost of stay data was obtained and analyzed using Mann-Whitney U test to compare non-parametric variables. RESULTS: Eight hundred and forty-nine laparoscopic appendectomies were performed for uncomplicated appendicitis during the study period, of which 382 resulted in same-day discharge and 467 in an admission for observation. Univariate analysis revealed no statistical difference between readmission rates for same day vs. observation (2 vs. 6 patients; P=0.21) or in emergency department visits within 30 days (22 vs. 27 patients; P=0.98). There was no difference in the number of surgical site infections or extra clinic visits. There was a significantly lower median cost of stay for patients discharged home the same day at 29,150 dollars (25,644, 32,276, IQR) compared to a median of 34,827 dollars (31,154, 39,457, IQR) (P<0.0001). CONCLUSIONS: Same-day discharge for laparoscopic uncomplicated appendectomy should be the new standard of care. This study found no differences in outcomes between the timing of discharge, with a significantly lower cost of stay for patients discharged home the same day.

Trainee Reliance on Public Service Loan Forgiveness.

OBJECTIVE: The Public Service Loan Forgiveness (PSLF) program is an option to trainees to help alleviate federal education debt. The prevalence of PSLF utilization and how this may impact career decisions of trainees is unknown. The purpose of this study was to understand the prevalence, impact, and understanding of PSLF participation on trainees. DESIGN: IRB-approved anonymous survey asking study subjects to report demographics, financial status, and reliance on PSLF. In addition, study subjects were asked to report their participation in PSLF, the possible impact of PSLF participation on career decisions, and to identify the qualifications needed to complete PSLF. SETTING: Online anonymous survey. PARTICIPANTS: The survey was offered to all physician trainees in all specialties at the University of Texas, Southwestern, University of Wisconsin, Madison, and University of Michigan, Ann Arbor. RESULTS: There were 934 respondents, yielding a 37.6% response rate. A total of 416/934 (44.5%) respondents were actively or planning on participating in the PSLF program with 175/934 (18.7%) belonging to a surgical specialty. Those belonging to a surgical specialty were more likely to be PSLF participants compared to medical specialties (53.1% versus 42.6%, p = 0.01). For those participating in PSLF, 82/416 (19.7%) stated this participation impacted career decisions. A total of 275/934 (29.4%) respondents obtained and 437/934 (46.8%) wanted to receive formal training/lectures in regards to the PSLF program. Of those actively or planning on participating in the PSLF program, only 58/416 (13.9%) were able to correctly identify all of the qualifications/criteria to complete the program. CONCLUSIONS: A large proportion of trainees rely on the PSLF program for education loan forgiveness with approximately 20% reporting participation impacted career decisions. Additionally, the majority may not fully understand PSLF criteria. Programs should strongly consider providing a formal education regarding PSLF to their trainees.

R-Spondin1 enhances wnt signaling and decreases weight loss in short bowel syndrome zebrafish.

BACKGROUND: R-spondins, including R-spondin 1 (RSPO1), are a family of Wnt ligands that help to activate the canonical Wnt/ß-catenin pathway, which is critical for intestinal epithelial cell proliferation and maintenance of intestinal stem cells. This proliferation underpins the epithelial expansion, or intestinal adaptation (IA), that occurs following massive bowel resection and short bowel syndrome (SBS). The purpose of this study was to identify if recombinant human RSPO1 (rhRSPO1) could be serially administered to SBS zebrafish to enhance cellular proliferation and IA. METHODS: Adult male zebrafish were assigned to four groups: sham + PBS, SBS + PBS, sham + rhRSPO1, and SBS + rhRSPO1. Sham fish had a laparotomy alone. SBS fish had a laparotomy with distal intestinal ligation and creation of a proximal stoma. Fish were weighed at initial surgery and then weekly. rhRSPO1 was administered post-operatively following either a one- or two-week dosing schedule with either 3 or 5 intraperitoneal injections, respectively. Fish were harvested at 7 or 14 days with intestinal segments collected for analysis. RESULTS: Repeated intraperitoneal injection of rhRSPO1 was feasible and well tolerated. At 7 days, intestinal epithelial proliferation was increased by rhRSPO1. At 14 days, SBS + rhRSPO1 fish lost significantly less weight than SBS + PBS fish. Measurements of intestinal surface area were not increased by rhRSPO1 administration but immunofluorescent staining for ß-catenin and gene expression for cyclin D1 was increased. CONCLUSIONS: Intraperitoneal injection of rhRSPO1 decreased weight loss in SBS zebrafish with increased ß-catenin + cells and cyclin D1 expression at 14 days, indicating improved weight maintenance might result from increased activation of the canonical Wnt pathway.

Normalization of Serum Lipase Levels Versus Resolution of Abdominal Pain: A Comparison of Preoperative Management in Children With Biliary Pancreatitis.

BACKGROUND: Controversy exists over the timing of cholecystectomy for biliary pancreatitis in children. Some surgeons await normalization of serum lipase levels while others are guided by resolution of abdominal pain; however, there are minimal data to support either practice. We hypothesized that resolution of abdominal pain is equivalent in outcome to awaiting normalization of lipase levels in patients undergoing cholecystectomy for biliary pancreatitis. METHODS: After institutional review board (IRB) approval, the medical record was retrospectively queried for all cases of cholecystectomy for biliary pancreatitis at our institution from 2007 to 2017. Patients undergoing chemotherapy, admitted for another cause, or who had severe underlying comorbidities like ventilator dependence were excluded. Patients were stratified into two cohorts: those managed preoperatively by normalization of serum lipase levels versus resolution of abdominal pain. Demographics, serum lipase levels, postoperative complications, cost of stay, readmissions, and return to the emergency department were collected and analyzed using multivariate regression. RESULTS: Seventy-four patients met inclusion: 29 patients had lipase levels trended until normalization compared with 45 patients who had resolution of abdominal pain prior to cholecystectomy. Among the two cohorts there was no statistical difference in age, gender, race, ethnicity, or type of preoperative imaging used. Trended patients were found to have more serum lipase levels tested (8.5 ± 6.2 versus 3.4 ± 2.5, P < 0.0001). The trended lipase cohort was significantly more likely to require preoperative total parenteral nutrition (48% versus 11%, P = 0.007) and consequently a longer time before resuming a diet (10 ± 7.3 versus 4.6 ± 2.4 d, P < 0.0001). When comparing the two groups, we found no significant difference in the duration of surgery, postoperative complications, or readmissions. Lipase trended patients had a significantly longer length of stay compared with nontrended patients (11.5 ± 8.1 versus 4.2 ± 2.3 d, P < 0.0001) and had a higher total cost of stay ($38,094 ± 25,910 versus $20,205 ± 5918, P = 0.0007). CONCLUSIONS: Our data suggest that in children with biliary pancreatitis, proceeding with cholecystectomy after resolution of abdominal pain is equivalent in outcomes to trending serum lipase levels but is more cost-effective with a decreased length of stay and decreased need for preoperative total parenteral nutrition.

No pain is gain: A prospective evaluation of strict non-opioid pain control after pediatric appendectomy.

INTRODUCTION: Opiates are often prescribed after pediatric operations despite safety concerns and lack of evidence confirming superiority compared to other pain control modalities. In this study, we use daily parental surveys to prospectively evaluate a strict non-opioid pain control strategy after laparoscopic appendectomy. METHODS: After IRB approval, children who underwent laparoscopic appendectomy for nonperforated acute appendicitis were recruited to the study. For these patients, our standard practice is to provide instructions to administer alternating acetaminophen and ibuprofen over-the-counter (OTC) postoperatively, and no opiate prescriptions are written. Parents of enrolled children received a daily RedCap survey via text message or e-mail on postoperative days (POD) 1 through 5 to prospectively assess pain control and medication usage. Trends were compared across postoperative days. RESULTS: One hundred twenty patients were enrolled in the study, and none received opiate prescriptions. Postoperative pain survey response rates were 54% on POD1, 47% on POD2, 35% on POD3, 34% on POD4, and 29% on POD5. Pain level was 4.7 ±â€¯2.3 (out of 10) on POD1, and down-trended significantly each postoperative day to reach 0.7 ±â€¯1.2 by POD5. On POD1, 85% of parents administered OTC medications, which reduced significantly to 14% by POD5. Parent-reported success rates to manage pain by OTC regimen were 85% on POD1, 94% on POD2, 91% on POD3, and 100% on POD4 and POD5. CONCLUSION: Strict non-opioid pain control after appendectomy exhibits high performance based upon prospective parental surveys. This strategy should be implemented as standard of care and tested for application to other surgical conditions. LEVEL OF EVIDENCE: Level II.

More Is Less: The Advantages of Performing Concurrent Laparoscopic Cholecystectomy and Endoscopic Retrograde Cholangiopancreatography for Pediatric Choledocholithiasis.

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) are standard of care for pediatric choledocholithiasis. Patients typically undergo separate procedures during hospitalization. Collaboration between surgical and gastroenterology services led to performance of both procedures concurrently during one anesthetic. We hypothesized that concurrent procedures would reduce costs without increasing complications as compared with separate procedures. Materials and Methods: We evaluated patients admitted to our institution from 2013 to 2018 with choledocholithiasis who underwent both ERCP and LC during the same admission. Fourteen patients underwent both procedures during concurrent anesthetic. Forty-two patients who underwent LC and ERCP under separate anesthetics were randomly selected to perform a 3:1 matched case-control study. Demographic and clinical data were collected, including imaging and laboratory findings, outcomes, and costs. Comparative analysis was completed with Fisher's exact and Mann-Whitney U tests. Results: On presentation, there was no difference in common bile duct size, total bilirubin, or white blood cell count between the concurrent and separate procedure cohorts. Significantly, there was no difference in total length of anesthesia (117.9 ± 40 minutes versus 119.6 ± 52 minutes, P = .747). There were also no differences in complications, emergency department visits, or readmissions. Patients who underwent concurrent procedures had significantly lower total cost of stay ($45,597 ± 11,513 versus $61,008 ± 17,960, P = .006). Conclusions: In pediatric patients with choledocholithiasis, performing LC and ERCP may be performed concurrently during one anesthetic, which decreases costs without increasing in anesthesia time or complications.

An investigation of social determinants of health and outcomes in pediatric nonaccidental trauma.

OBJECTIVES: Nonaccidental trauma (NAT) is a leading cause of pediatric mortality and disability. We examined our institution's experience with NAT to determine if socioeconomic status is correlated with patient outcomes. METHODS: NAT cases were reviewed retrospectively. Socioeconomic determinants included insurance status and race; outcomes included mortality, discharge disability and disposition. Correlations were identified using t test, Fisher's exact test, and logistic regression. RESULTS: The cohort comprised of 337 patients, with an overall uninsured rate of 5.6%. This rate was achieved by insuring 64.7% of the cohort after admission. Non-survivors were more likely to have no insurance coverage (14.8% versus 4.8%, p = 0.041). Regression revealed that uninsured had 8 times (95% CI 1.7-38.7, p = 0.008) higher in-hospital mortality than those with insurance when controlling for injury severity. Additionally, injury severity score ≥ 15, transfer from outside hospital, need for ICU or operative treatment were predictive of mortality. Adjusted risk factors for severe disability at discharge did not include insurance status or race, while ISS ≥ 15 and ICU stay were predictive. CONCLUSIONS: There are significant associations of insurance status with pediatric NAT outcomes, highlighting that determinants other than disease severity may influence mortality and morbidity. High-risk patients should be identified to develop strategies to improve outcomes.

Does Microscopic Hematuria After Pediatric Blunt Trauma Indicate Clinically Significant Injury?

BACKGROUND: Children are more likely to have urinary system injury after blunt abdominal trauma (BAT) because of anatomical vulnerabilities. Urinalysis (UA) is often performed during initial evaluation to screen for injury. The purpose of this study was to determine how often finding microscopic hematuria after BAT leads to further testing and whether this indicates a significant injury. METHODS: A retrospective review of children evaluated for BAT at Children's Health from 2013 to 2017 was performed. Patients included had microscopic hematuria on initial UA. Data collected included demographics, injury data, laboratory and imaging data, and outcomes. Analysis was performed using descriptive statistics, Fisher's exact, and independent t-test. RESULTS: Of 1059 patients treated for BAT during the study period, 203 (19%) exhibited microscopic hematuria on UA during the initial workup. Most UAs resulted after imaging was completed and did not impact management (158, 78%); twenty-two (14%) of these patients had urinary injury, which were diagnosed by imaging regardless of UA results. Forty-five (22%) patients were found to have microscopic hematuria that independently led to workup for urinary injury. Of these, nine patients had a urinary system injury: 6 low-grade renal and three bladder wall injuries, none of which required surgery. Those with and without urinary injury in this group underwent similar numbers of radiographic studies. CONCLUSIONS: Microscopic hematuria on screening UA after BAT may lead to extensive workup, regardless of the presence of symptoms. In patients who receive cross-sectional abdominal imaging, preceding UA adds little to the clinical workup of children with BAT.

Clinical and Imaging Correlates of Pediatric Mucosal Appendicitis.

BACKGROUND: Mucosal appendicitis is a controversial entity that is histologically distinct from transmural appendicitis. There is mixed opinion regarding mucosal inflammation as a spectrum of appendicitis versus a negative appendectomy. The ability to distinguish these diagnoses preoperatively is of importance to prevent unnecessary surgery. We hypothesize that patients with mucosal appendicitis can be discriminated from those with transmural disease based on specific preoperative clinical and imaging findings. MATERIALS AND METHODS: After IRB approval, all patients who underwent laparoscopic appendectomy at our institution during 2015 were reviewed in the electronic medical record. Patients with mucosal appendicitis were identified and matched 2:1 to a random cohort of nonperforated transmural appendicitis cases. Demographic and clinical data were collected, including history, examination, laboratory, and imaging findings. Preoperative factors associated with mucosal appendicitis were modeled using binomial logistic regression analysis. RESULTS: Of 1153 appendectomies performed during 2015, 103 patients had pathologic diagnosis of mucosal appendicitis. When compared with patients with mucosal infection, leukocytosis >10,000 per microliter led to 5.9 times higher likelihood of transmural pathology (P = 0.000). Noncompressibility on ultrasound was associated with 7.3 times higher likelihood of transmural disease (P = 0.015). Echogenic changes were predictive of transmural appendicitis, conferring 3.9 times the risk (P = 0.007). Presence of free fluid led to 2.3 times the rate of transmural pathology (P = 0.007). Finally, for every millimeter decrease in appendiceal diameter, patients were half as likely to exhibit transmural disease (P = 0.000). Together, these variables can successfully predict presence of mucosal appendicitis on final pathology report at a rate of 82.1%, and explain 60% of the variance in diagnosis of mucosal versus transmural appendicitis (P = 0.000). CONCLUSIONS: Mucosal appendicitis remains a controversial pathologic entity, but is not associated with greater complications compared with transmural appendicitis when treated with laparoscopic appendectomy. Transmural disease can be predicted by leukocytosis, noncompressible appendix, presence of free fluid, larger appendiceal diameter and echogenicity.

Diagnostic Utilization and Accuracy of Pediatric Appendicitis Imaging at Adult and Pediatric Centers.

BACKGROUND: Diagnostic imaging in pediatric appendicitis may decrease rates of negative appendectomy and identify alternate pathologies. We compared imaging practices for children transferred from nonpediatric facilities versus directly admitted to our tertiary children's hospital for laparoscopic appendectomy, and assessed the diagnostic accuracy in each population based on final pathologic diagnosis. MATERIALS AND METHODS: After institutional review board approval, all cases of laparoscopic appendectomy at our children's hospital during 2015 were reviewed. Demographic and clinical data were collected, including age, transfer status, imaging studies, and pathologic diagnosis. Imaging practices in patients transferred from adult centers were compared with those directly admitted. RESULTS: There were 1153 included patients who underwent laparoscopic appendectomy for acute appendicitis during the study period, with 242 (20.9%) presenting as transfers from nonpediatric facilities. Of these, 73.5% underwent preoperative computed tomography (CT), compared with 26.4% of nontransfer patients (P < 0.000). All remaining patients received ultrasound (US). Despite variation in imaging strategies, rates of negative appendectomy were similar in transfer and nontransfer groups (1.7% versus 2.0%, respectively, P = 0.744). There were marginal differences in sensitivity of US and CT to detect appendix features between the transferring and referral centers. CONCLUSIONS: Our results show that nonpediatric facilities use CT more frequently to diagnose pediatric appendicitis. Rates of nontherapeutic surgery were equivalent between transferred and directly admitted patients, which is likely related to high performance of both imaging strategies. Transferring centers should strive to rely more heavily on US, which may require education and development of improved pediatric US capacity.

Correlation of payor status and pediatric transfer for acute appendicitis.

BACKGROUND: Tertiary referral centers provide specialty and critical care for patients presenting to hospitals that lack these resources. There is a notion among tertiary centers that outside hospitals are more likely to transfer uninsured or underinsured patients. We examined funding status of patients transferred to our tertiary pediatric hospital for surgical management of appendicitis, hypothesizing that transferred patients were more likely to have unfavorable coverage. MATERIALS AND METHODS: The electronic medical record was queried for all cases of laparoscopic appendectomy at our hospital between 2011 and 2015. Insurance was grouped into three categories: commercial, Medicaid/Children's Health Insurance Plan, or none. Transferred patients were compared to patients who presented directly. RESULTS: A total of 5758 patients underwent laparoscopic appendectomy during the study period, of which 1683 (29.2%) were transfer patients. Transfer patients were more likely to be older, with a median age of 10.5 y versus 9.8 y in nontransferred patients (P ≤ 0.0001), and were more likely to be identified as non-Hispanic (50.0% versus 36.5%; P ≤ 0.0001). Insurance coverage was similar between groups. However, subgroup analysis of the hospitals that most frequently used our transfer services revealed a trend to transfer a higher proportion of Medicaid/Children's Health Insurance Plan patients. CONCLUSIONS: Overall, pediatric patients transferred for laparoscopic appendectomy had similar insurance coverage to patients admitted directly, but subgroup analysis shows that not all centers follow this trend. Transfer patients were more frequently older and non-Hispanic. This builds upon the existing literature regarding the correlation of funding and transfer practices and highlights the need for additional research in this area.
