Background: Primary spontaneous pneumothorax (PSP) affects 3.4 per 100,000 children in the United States. Regardless of the initial management, additional procedures, and prolonged hospital length of stay (LOS) may occur. There is currently no consensus in the pediatric surgical community on the optimal management of these patients, which has resulted in marked variability in management. The Midwest Pediatric Surgery Consortium (MWPSC), of which our site is a participant, suggested a management algorithm to include simple aspiration upon presentation, and if this fails, VATS should be considered.

Objectives/Goal: The purpose of this study was to evaluate the outcomes of instituting a …

Institutional Outcomes Of Blunt Liver & Splenic Injury In The Atomac Era, Shai Stewart Md, James Fraser, Rebecca M. Rentea, Pablo Aguayo, David Juang, Jason D. Fraser, Charles L. Snyder, Richard J. Hendrickson, Shawn D. St.Peter, Tolulope A. Oyetunji

Research Days

Background: The Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium (ATOMAC) practice management guideline (PMG) was created to standardize management of blunt liver or spleen injury (BLSI) across pediatric trauma centers. Evaluations of institutional outcomes after its adoption remain scarce. We describe our outcomes since PMG adoption at our institution.

Objectives/Goal: The purpose of this study was to assess patient outcomes and resource utilization after implementation of this protocol. We hypothesized there is no difference in length of stay (LOS) or complications regardless of grade of isolated injuries to the liver or spleen. In addition, there is limited guidance on the management of concurrent injuries to …

Predicting Avascular Necrosis After Unstable Slipped Capital Femoral Epiphysis, Jonathan Warren, Alexander Metoxen, Michael Held, Brant Ansley, Berglund Lisa

Research Days

Background: There is no consensus in the literature on the risk of developing avascular necrosis (AVN) after unstable slipped capital femoral epiphysis (SCFE). In recent years, a number of studies have sought to better characterize risk factors for AVN in this population. However, to the best of our knowledge, there is no study that uses predictive modeling to assess the chance of developing AVN based on different patient-centric factors.

Objectives/Goal: Our goal is to assess whether or not previously-published risk factors for AVN in unstable SCFE such as duration of symptoms, reduction type, type of surgery, timing of surgery, and …

Laparoscopic Versus Open Inguinal Hernia Repair: A Single Institution Comparison Of 1200 Patients, Shai Stewart Md, Wendy Jo Svetanoff, James Fraser, Rebecca M. Rentea, Pablo Aguayo, David Juang, Jason D. Fraser, Charles L. Snyder, Richard J. Hendrickson, Shawn D. St.Peter, Tolulope A. Oyetunji

Research Days

Background: : Laparoscopy has become the standard of care for many pediatric surgical procedures; however, there is no consensus regarding the optimal approach for inguinal hernia repair (IHR). We report our experience over an 8-year period with open and laparoscopic inguinal hernia repair (LIHR).

Objectives/Goal: We aim to describe our experience within a free-standing tertiary care pediatric institution and compare outcomes between open and laparoscopic repair of pediatric inguinal hernias.

Methods/Design: A retrospective review of patients under 18 years who underwent IHR between June 2010 and June 2017 was performed. The open technique utilizes high ligation of the internal ring, …

A Novel Approach For Laparoscopic Direct Inguinal Hernia Repair In Children, Shai Stewart Md, Charlene Dekonenko, Nelimar Cruz-Centeno, Derek Marlor, Jason D. Fraser

Research Days

Background: Inguinal hernia repair is one of the most common operations performed by pediatric surgeons, and the frequency of laparoscopy for repair is increasing. The vast majority of these are indirect hernias and therefore how to best repair a direct defect when seen during laparoscopy is still unknown. Simple high ligation of the hernia sac (as is done in an indirect hernia) does not repair the inguinal floor weakness/defect seen in a direct hernia.

Objectives/Goal: We therefore present a case of laparoscopic bilateral indirect and direct inguinal hernia repair, commonly known as pantaloon hernia, repaired without mesh and utilizing the …

Institutional Use Of Ultrasound In The Evaluation Of Cryptorchidism, Shai Stewart Md, Dae H. Kim, Nelimar Cruz-Centeno, Derek Marlor, James Fraser, Tolulope A. Oyetunji Md Mph, Shawn D. St.Peter

Research Days

Background, Objectives/Goal, Methods/Design, Results, Conclusions limited to 500 words Background: In 2014, the American Urological Association guidelines recommended against the performance of ultrasound and other imaging modalities in the evaluation of patients with cryptorchidism prior to expert consultation. We hypothesized that ultrasound remains overused by referring physicians.

Objectives/Goal: We aimed to examine our institutional experience and measure adherence to currently available guidelines.

Methods/Design: An institutional review board (IRB) approved retrospective review of ultrasound utilization in the evaluation of patients with cryptorchidism was performed from June 1, 2016, to June 30, 2018, at a single tertiary level pediatric hospital.

Antibiotic Monotherapy Vs Dual-Drug Therapy In Perforated Appendicitis: Single Center Retrospective Review, Shai Stewart Md, Nelimar Cruz-Centeno, Derek Marlor, Dae H. Kim, Shawn D. St Peter, Tolulope A. Oyetunji Md Mph

Research Days

Background: The optimal antibiotic regimen in perforated appendicitis to reduce intraabdominal abscess (IAA) formation has not yet been agreed upon in the pediatric surgery community. We aimed to evaluate the outcomes of patients with perforated appendicitis when intravenous antibiotic monotherapy with Piperacillin-Tazobactam (PT) versus dual-drug therapy with Ceftriaxone and Metronidazole (CM) are administered. We hypothesized there is no difference in the rate of IAA formation with antibiotic monotherapy, as opposed to our once-daily dosed, institutional standard dual-drug therapy.

Objectives/Goal: The goal was to determine if our current management protocols for acute appendicitis were delivering the best possible results for our …

Introduction: Initial management of hypertrophic pyloric stenosis (HPS) is correction of electrolyte disturbances with fluid resuscitation. In 2015, our institution implemented a fluid resuscitation protocol based on previous data that focused on minimizing blood draws and allowing immediate ad libitum feeds postoperatively. Here we describe the protocol and subsequent outcomes. Methods: We conducted a single-center retrospective review of patients diagnosed with HPS from 2016-2020. All patients were managed per the protocol outlined in Figure 1. All were given formula or breast milk after the post-anesthesia care unit and discharged home after tolerating three consecutive feeds. Feedings were given every 2-3 …

Persistent Pediatric Breast Abscesses Following Initial Treatment At Tertiary And Community Centers, Derek Marlor, Kayla B. Briggs, Shai Stewart Md, Nelimar Cruz-Centeno, Charlene Dekonenko, Tolulope A. Oyetunji, Jason D. Fraser

Presentations

Introduction: Our institution previously reported on outcomes of children with untreated and not spontaneously draining breast abscesses. This study aimed to evaluate the outcomes of all patients with breast abscesses who were evaluated at our institution. Methods: Following IRB approval, all patients < 18-years-old with breast abscesses were included. A total of 145 patients treated from January 2008-December 2018 were identified. Patients were divided into 2 groups; Group 1 included patients initially evaluated at our institution and Group 2 included patients who were initially evaluated at referring centers. The primary outcome was disease persistence. Secondary outcomes were antibiotic utilization, number and type of procedures performed, and risk factors for recurrence. Statistical analysis was performed using STATA® 17 with a p-value of <0.05 indicating significance. Results: A total of 145 patients were identified: 111 (76.6%) in Group 1 and 34 (23.4%) in Group 2. Demographics were similar between groups. Of the 111 patients in Group 1, 2 (1.8%)) were treated with observation alone, 58 (52.3%) were treated with antibiotics alone, 26 (23.4%) were treated with aspiration, and 25 (22.5%) were treated with incision and drainage. Of the 34 patients in Group 2, 4 (11.8%) were treated initially with observation, 22 (64.7%) with antibiotics alone, 5 (14.7%) with manual expression, 2 (5.9%) with incision and drainage, and 1 (2.9%) with warm compresses. Patients in Group 1 were more likely to receive needle aspiration (23.4% vs. 0%; p<0.001) or incision and drainage (22.5.% vs. 5.9%; p<0.001) as initial treatment. Compared to Group 2, patients in Group 1 were more likely to be prescribed clindamycin when treated with antibiotics alone (69.9% vs 18.2%; p<0.001). They also had a 12.6% persistent disease rate (n=14). Second treatment in those with persistent disease included aspiration in 50% (n=7), incision and drainage 45.5% (n=5), antibiotics 7.1% (n=1), and manual expression 7.1% (n=1). No patients had persistent disease following second treatment. Patients in Group 2 were more likely to be treated with antibiotics alone (64.7% vs. 52.3%; p<0.001), with trimethoprim/sulfamethoxazole being the most commonly prescribed antibiotic (54.6%). In patients with persistent disease treated at our institution following initial evaluation at a referring center, 50.0% were treated with antibiotics alone, 26.5% with aspiration, 17.7% with incision and drainage, and 5.9% with manual expression. Following treatment at our institution, the rate of persistent disease was similar between groups (12.6% vs 11.8%;). Conclusions: Persistent breast abscesses may be treated with antibiotics alone in community and tertiary care centers. Disease persistence is similar regardless of the initial treatment setting.

Management of Primary Spontaneous Pneumothorax in Children: A Single Institution Protocol Analysis

Background: The Midwest Pediatric Surgery Consortium (MWPSC) has suggested a management algorithm to include simple aspiration of primary spontaneous pneumothorax (PSP), failing which, Video-Assisted Thoracoscopic Surgery (VATS) should be considered. We describe our outcomes in patients who have been managed with this suggested protocol.

Methods: An Institutional Review Board (IRB) approved, single institution retrospective analysis was conducted on all patients between 12 and 18 years who were diagnosed with PSP from 2016 to 2022. Initial management consisted of aspiration alone with a 12F Thal-Quick chest tube followed by …

Endoscopic Retrograde Cholangiography Using A Colonoscope In A Pediatric Liver Transplant Patient With Roux-En-Y Biliary Anastomosis, Nadia Ibrahimi, Thomas M. Attard, Ryan T. Fischer, Voytek Slowik, Richard J. Hendrickson, Bhargava Mullapudi, Moises Alatorre-Jimenez, Syed Jafri

Posters

Introduction: Biliary ducal sequelae including occlusions, strictures, leaks, or necrosis frequently complicate pediatric liver transplantation. The underlying etiology includes prolonged intraoperative ischemia or postoperative arterial inflow obstruction. In adult patients the role of endoscopic retrograde cholangiography (ERC) is well established in the management of biliary complications post-liver transplantation. In contrast, in the pediatric population, due to the combination of small patient size and the complexity of Roux-en-Y anastomotic techniques, ERC has been described as difficult or virtually impossible. This limits the options available for managing biliary duct complications to percutaneous techniques Endoscopic management of biliary complications in pediatric patients with …

Racial Disparities in Testicular Torsion Introduction: Testicular torsion (TT) is a surgical emergency requiring prompt intervention to preserve testicular function. Race and insurance status are thought to be associated with higher rates of gonadal loss; however, reports in the literature are conflicting. We sought to determine the effect of race on the treatment and outcomes of testicular torsion. Methods: Following IRB approval, a retrospective review was conducted of patients <18 years of age who presented to 2 institutions (hereby referred to as H1 and H2) with acute scrotal pain between December 2017 and September 2019. Demographic data, clinical history, imaging results, diagnosis, and surgical outcomes were recorded. Social vulnerability index (SVI), as determined by zip code, was obtained from the Centers for Disease Control and dichotomized using the 75th percentile. Higher SVI denotes increased social vulnerability. Primary outcome was diagnosis of TT. Secondary outcomes included orchiectomy rates. A p-value <0.05 was considered significant. Results: A total of 515 patients (H1 85%, H2 15%) were included in the final analysis. There were no difference in median age, BMI, TT diagnosis and orchiectomy rate between the two institutions. H2 treated more black patients (43% vs. 14%, p=<0.01) and patients with public insurance (57% vs. 41%, p=0.03) compared to H1. In multivariate analysis, older age was associated with TT (median age TT 14.12 years [12.13,15.69]) vs. no TT 9.86 years [5,13.05], OR 1.35, 95% CI 1.18-1.55, p=<0.01). Black patients were ~4 times more likely (OR 4.05, 95% CI 2.13-7.69, p=<0.01) than white patients to be diagnosed with TT when controlled for dichotomized SVI, insurance, and age. In the same model, Hispanic patients were ~2 times more likely (OR 2.20, 95% CI 1.10-4.40, p=0.03) to be diagnosed with TT when compared to white patients. Despite more black and Hispanic patients having dichotomized SVI >75th percentile than white patients (70% and 82%, respectively vs. 16%, p=<0.01), dichotomized SVI was not found to be associated with higher rates of TT or orchiectomy, respectively. Conclusion: At the two centers, more black and Hispanic children had SVI >75th percentile, however, when controlling for this in multivariate analysis, they were significant more likely to be diagnosed with …

Short And Long Term Outcomes Of Using Cryoablation For Post-Operative Pain Control In Patients After Pectus Excavatum Repair, James Fraser, Kayla B. Briggs, Wendy Jo Svetanoff, David Juang, Pablo Aguayo, Jason D. Fraser, Charles L. Snyder, Tolulope A. Oyetunji, Shawn D. St. Peter Md

Posters

Background: Previous prospective trials have demonstrated that intercostal cryoablation reduces length of stay and postoperative opioid consumption compared with thoracic epidural and patient controlled analgesia (PCA) modalities. We report the findings of a 3-year prospective, observational study to elucidate long-term pain control, symptoms, and complications with attention to postoperative short and long-term pain control associated with the cryoablation technique.

Methods: Following IRB approval, we prospectively collected data on patients who underwent bar placement for pectus excavatum with thoracoscopic intercostal cryoablation by six surgeons at our institution from 2017 to 2021. Patients and their parents completed surveys regarding pain scores, narcotic …

Assessing Early Use And Complications Of Gastrostomy Blended Feeds., James Fraser, Kristen L. Sayers, Amy L. Pierce, Beth A. Orrick, Wendy Jo Svetanoff, Tolulope A. Oyetunji Md Mph, Shawn D. St Peter

Posters

Providers are hesitant to recommend using blended tube feeds (BF) after gastrostomy tube (GT) placement due to increased risk of bacterial contamination, nutrition inadequacy, tube blockages, and lack of data addressing clinical outcomes. Caregivers often feel that BF are more natural, better tolerated, and more cost-effective. We studied early use of BF, potential complications, and satisfaction among caregivers.

Reconsidering Perioperative Antibiotic Use In Elective Laparoscopic Cholecystectomy, Kayla B. Briggs, James Fraser, Wendy Jo Svetanoff, Charles L. Snyder, Pablo Aguayo, David Juang, Rebecca M. Rentea, Jason D. Fraser, Shawn D. St. Peter Md, Tolulope A. Oyetunji

Posters

Introduction: Prophylactic preoperative antibiotics (PPA) are questionable in cases with a low rate of surgical site infection (SSI). We report institutional PPA usage and SSI rates after elective laparoscopic cholecystectomy in a children’s hospital. Methods: Children <18 years old who underwent outpatient laparoscopic cholecystectomy between 7/2010 and 8/2020 were included. SSI was defined as clinical signs of infection, requiring antibiotics, within 30 days of surgery. Results: 502 patients met inclusion criteria; 50% were pre-operatively diagnosed with symptomatic cholelithiasis, 47% biliary dyskinesia, 2% hyperkinetic gallbladder, and 1% gallbladder polyp(s). The majority were female (78%) and Caucasian (80%). 60% (n=301) of patients received PPA while 40% (n=201) did not; 1.3% (n=4) of those who received PPA developed SSI compared to 5.5% (n=11) of those who did not (p=0.01). Though PPA use was associated with an 84% reduction in risk of SSI on multivariate analysis (p=0.01), all SSIs were superficial. One child required readmission for intravenous antibiotics while the remainder were treated with outpatient antibiotics. Gender, age, BMI, ethnicity, and preoperative diagnosis did not influence the likelihood of receiving PPA (Table 1). Conclusion: Given the relatively low morbidity of the superficial SSI, conservative use of PPA should be carefully considered in outpatient laparoscopic cholecystectomy to avoid contributing to antibiotic-related complications.

Umbilical Access In Laparoscopic Surgery In Infants Less Than 3 Months: Single Institution Retrospective Review, James Fraser, Kayla B. Briggs, Wendy Jo Svetanoff, Rebecca M. Rentea, Pablo Aguayo, David Juang, Jason D. Fraser, Charles L. Snyder, Richard J. Hendrickson, Shawn D. St Peter, Tolulope A. Oyetunji

PURPOSE: Umbilical access in laparoscopic surgery has been cited as a potential factor for increased complications in low birth weight infants and those less than three months old. Previous series noted a self-reported complication rate of 10.6% among 329 pediatric surgeons via anonymous survey, citing carbon dioxide (CO2) embolism as the most common complication. We report four-year outcomes with blunt transumbilical laparoscopic access to examine the safety of this technique. METHODS: Following IRB approval, a retrospective database of patients less than three months of age who underwent laparoscopic pyloromyotomy or inguinal hernia repair from 2016-2019 at a tertiary care academic …

Infliximab As Rescue Therapy In Pediatric Severe Colitis, Kayla B. Briggs

Research Days

Background: Infliximab has been shown to be effective in achieving clinical remission in patients with ulcerative colitis (UC) refractory to conventional therapy. However, there is conflicting data in the literature regarding its effectiveness as rescue therapy in acute severe colitis. Furthermore, most studies were conducted in adults, and pediatric onset of inflammatory bowel disease (IBD) is associated with more severe disease that may be less amenable to rescue therapy.

Objectives/Goal: We reviewed our experience with pediatric severe colitis and report outcomes following attempted rescue therapy with infliximab.

Methods/Design: A retrospective review was conducted of patients with UC or indeterminate colitis …

Unique Evaluation And Management Considerations For Adolescents With Late Gynecologic And Colorectal Issues In The Setting Of Anorectal Malformations, Wendy Jo Svetanoff

Reconsidering Perioperative Antibiotic Use In Elective Laparoscopic Cholecystectomy, Kayla B. Briggs

Research Days

Background: As rates of antimicrobial resistance increase, the use of prophylactic perioperative antibiotics (PPA) has been questioned in cases with a low risk of surgical site infection (SSI). In laparoscopic cholecystectomy performed for biliary dyskinesia, hyperkinetic gallbladder, and gallbladder polyps, the use of PPA varies with no widely accepted practice pattern.

Objectives/Goal: We examined institutional PPA usage and SSI rates for elective laparoscopic cholecystectomy to determine if PPAs are indicated.

Methods/Design: Following IRB approval, children/2010 and 8/2020 for symptomatic cholelithiasis, biliary dyskinesia, hyperkinetic gallbladder, and/or gallbladder polyps were included. Several surgeons changed practice to selective PPA use in 2016, decreasing …

The Power Of Outpatient Botulinum Injections In Preventing Hirschsprung Associated Enterocolitis, Wendy Jo Svetanoff

Research Days

Background: Hirschsprung associated enterocolitis (HAEC) is a potentially life-threatening complication, where the child often presents with obstructive symptoms. Failure of the internal anal sphincter (IAS) to relax is thought to play a role in these symptoms. Botulinum toxin (BT) injections assist in temporarily relieving obstructive symptoms due to IAS achalasia in patients with Hirschsprung’s disease following surgical pull-through. The use of BT may play a role in preventing HAEC episodes related to IAS dysfunction.

Objectives/Goal: Our aim was to determine the effect of scheduled outpatient Botulinum injections on the development of HAEC.

Methods/Design: A retrospective review between July 2010 – …
