INTRODUCTION: We evaluated whether Trisomy 21 (T21) affected bowel management use, ability to toilet train for stool, and rates of Hirschsprung-Associated Enterocolitis (HAEC) in children with Hirschsprung disease (HD). We hypothesized that T21 would be associated with increased rates of HAEC, bowel management program (BMP) use, and delayed toilet training for stool.

METHODS: Children with HD in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) database who underwent primary pull-through were included and stratified by T21 status: HD only versus HD + T21. Children requiring a redo pull-through, initially managed with a stoma, or those who had inadequate follow-up were …

BACKGROUND: The risk of malignant transformation and recurrence of Sacrococcygeal Teratoma (SCT) is relatively high, while it is possibly lower in cases associated with Currarino Syndrome (CS). However, the existing literature gives contradictory results. We aimed to examine the risk of malignant transformation in a large cohort of SCT and CS patients.

METHODS: In a global retrospective cohort study, data of consecutive SCT patients and CS patients with presacral teratoma was obtained from 132 institutes in 62 countries. Malignant transformation, defined as malignancy at initial resection, malignant recurrence, or death due to malignancy was analysed for SCT and CS patients. …

The Influence Of Preoperative Bowel Preparation On Surgical Site Infection In Pediatric Colorectal Surgery., Katlyn G. Mckay, Naomi-Liza Denning, Rebecca M. Rentea, Eunice Y. Huang

Manuscripts, Articles, Book Chapters and Other Papers

Surgical site infection (SSI) is one of the most common nosocomial infections that occur in pediatric patients in the United States, with colorectal procedures consistently demonstrating the highest rates of SSI. Strategies to reduce SSI in colorectal surgery include standardized perioperative colorectal care bundles, which commonly incorporate preoperative bowel preparation. Robust adult literature exists supporting the use of mechanical bowel preparation in combination with oral antibiotics to mitigate SSI; however, pediatric evidence remains less definitive. Current pediatric literature shows heterogeneity of bowel preparation use amongst surgeons, with existing literature consisting primarily of small retrospective studies. A well-designed pediatric randomized controlled …

Switching Lanes: Leaving Behind Discharge Antibiotics And Laboratory Testing In Perforated Appendicitis, Seth Saylors, Cory Nonnemacher, Meredith Elman, Pablo Aguayo, Richard Hendrickson, David Juang, Irene Isabel P. Lim, Rebecca Rentea, Charles Snyder, Shawn St. Peter, Tolulope Oyetunji

Research Days

Purpose: Appendicitis is the most common surgical emergency in children with approximately 30% of patients presenting with perforation, defined as a hole in the appendix or a fecalith found in the abdomen, at time of surgery. Our previous protocol at time of discharge, with an 11% intraabdominal abscess (IAA) rate, included checking a white blood cell count (WBC) on day of discharge, with a value ≥10 serving as a trigger for additional outpatient oral antibiotics course. Beginning in May, 2023 we changed our protocol to no longer obtain WBC or prescribe outpatient antibiotics at time of discharge. The purpose of …

The Impact Of Cultures On Treating Abscesses Associated With Appendicitis, Cory Nonnemacher, Seth Saylors, Meredith Elman, Tolulope A. Oyetunji Md Mph, Shawn D. St Peter

Research Days

Background/Purpose

Perforated appendicitis is associated with elevated risk of post-operative intra-abdominal abscess (PIAA) formation. Small PIAAs can be successfully treated without drainage, while larger ones warrant Interventional Radiology drainage. Routine culture of drained abscesses occurs at most institutions, with some prior studies showing resistance rates of 40-50%, prompting change of post-drainage antibiotics. The purpose of our study is to evaluate if culture results impact the antimicrobial therapy chosen for patients with PIAA, with our hypothesis being that routine culture does not have a significant impact on patient outcomes.

Methods

Patients < 18 years of age who were treated for perforated appendicitis at a standalone tertiary children’s hospital from 2011 to 2024 were retrospectively evaluated for abscess formation and extracted those who underwent drainage procedures with abscess cultures to assess the need for antibiotic adjustments from the standard of care based on culture results.

Results

A total of 1736 patients treated for perforated appendicitis …

Delaying Infant Inguinal Hernia Repair Does Not Increase Incarceration Rate, Seth Saylors, Cory Nonnemacher, Charles Snyder, Pablo Aguayo, Richard Hendrickson, Bhargava Mullapudi, Irene Lim-Beutel, Rebecca Rentea, Shawn St. Peter, David Juang, Tolulope Oyetunji

Research Days

Introduction: Inguinal hernia repair is one of the most common pediatric surgical procedures performed with an estimated incidence of 1-5% in children. Patients can present with or without symptoms, with symptomatic hernias (incarcerated or strangulated) that may require emergent or urgent operative intervention. During the Covid-19 pandemic, restrictions, and shutdowns of elective surgeries at our institution resulted in delaying elective inguinal hernia repair unless presenting with more emergent symptoms, with no apparent increase in complication. In our institution, this practice was continued even after COVID restrictions were lifted, with elective repairs delayed until patients were older before completing elective inguinal …

Single-Incision Laparoscopic Ileocecectomy In Pediatric Crohn’S Disease: A 15-Year Experience, Seth Saylors, Cory Nonnemacher, Meredith Elman, Shawn St. Peter

Research Days

Purpose: In refractory Crohn’s disease, the terminal ileum is a common site requiring excision. Laparoscopic ileocecectomy is the procedure of choice and we use a single-incision laparoscopic technique (SILS). We have previously reported our experience with SILS ileocecectomy with a sizeable cohort compared to other series. This project aims to expand on our single institutional experience with SILS ileocecectomy and evaluate the impact of experience.

Methods: We completed a retrospective review of patients who underwent single-incision laparoscopic (SILS) ileocecectomy for Crohn’s disease from 1/1/2009-3/31/2024 at a single institution by a single surgeon. Operative and inpatient characteristics were collected to determine …

Implementation Of An Enhanced Recovery After Surgery Pathway In Adolescent Patients Undergoing Laparoscopic Evaluation Of Endometriosis, Lauren Roth Md, Madeline Ross Md, Todd Glenski Md, Emily Weisberg Md, Ashli Lawson

Research Days

This study evaluates the implementation of an Enhanced Recovery After Surgery (ERAS) pathway for adolescent patients undergoing diagnostic laparoscopy for endometriosis at a tertiary children's hospital. The retrospective reviewed included 53 patients (20 pre-ERAS, 33 post-ERAS) aged 12-20 years old, comparing preoperative compliance, intraoperative adherence, and postoperative outcomes. Findings showed 81% compliance with preoperative medication, 76% received appropriate preoperative medications, and 39% had recommended carbohydrate loading. Intraoperative compliance was 87%, with 61% adherence to postoperative medications. Post-anesthesia care unit (PACU) stay time increased (44 vs 53 minutes, p=0.21), but pain scores, postoperative prescriptions, and hospital readmissions remained unchanged. This study …


Bivalirudin Versus Heparin In Patients With Congenital Diaphragmatic Hernias Requiring Extracorporeal Life Support, Cory Nonnemacher, Seth Saylors, Vatche Melkonian, Richard Hendrickson, Inna Lobeck May 2025

Bivalirudin Versus Heparin In Patients With Congenital Diaphragmatic Hernias Requiring Extracorporeal Life Support, Cory Nonnemacher, Seth Saylors, Vatche Melkonian, Richard Hendrickson, Inna Lobeck

Research Days

Introduction

Congenital Diaphragmatic Hernia (CDH) is a rare congenital anomaly. The pulmonary hypoplasia, pulmonary hypertension and altered cardiac function associated with CDH may result in early cardiorespiratory failure requiring life-saving extracorporeal life support (ECLS). Early repair of CDH on ECLS has shown to improve survival, but poses an increased bleeding risk due to anticoagulation. Heparin has traditionally been the anticoagulant of choice for ECLS. Recent data has suggested that the use of bivalirudin may result in lower bleeding rates and transfusion requirements. This study aims to stratify complications for patients with CDH repaired on heparin versus bivalirudin, hypothesizing that complications …

Total Intestinal Atresia In A Neonate: A Case Report., Cory Nonnemacher, Seth Saylors, Naomi-Liza Denning, Vatche Melkonian, Pablo Aguayo

Manuscripts, Articles, Book Chapters and Other Papers

Intestinal atresias are a common cause of neonatal intestinal obstruction. An extremely rare variant is total intestinal atresia, where no lumen is appreciable from the duodenum through the colon. We describe a case of a 33-week female who was born at an outside hospital and underwent laparotomy for concern for intrauterine perforation and proximal intestinal obstruction. Laparotomy revealed a duodenal perforation and an atresia in the proximal jejunum. Resection of this segment revealed no intestinal lumen distally, and the patient was left in discontinuity and transferred to our tertiary children's hospital. Repeat laparotomy revealed atretic bowel with no lumen through …

Colonic Derotation Revisited: The "Deloyers Procedure" For Long-Segment Hirschsprung Disease., Ismael Elhalaby, Irene Isabel P. Lim, Elizaveta Bokova, Ifeanyi K Egbuchulem, Rebecca M. Rentea

Manuscripts, Articles, Book Chapters and Other Papers

Long-segment Hirschsprung disease (HSCR) presents significant challenges in surgical management, often requiring extensive bowel mobilization and creative techniques to achieve tension-free anastomosis. Colonic derotation offers a viable solution for preserving bowel length and maintaining the ileocecal valve, which is crucial for postoperative bowel function. The procedure involves extensive colonic mobilization and strategic vascular divisions of the right and middle colic vessels while preserving the ileocolic and marginal arteries, followed by a 180° counterclockwise rotation of the colon around the ileocolic vascular axis. Critical aspects include ensuring proper bowel orientation post-derotation, the careful assessment of potential compression points, and the preservation …

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Sacrococcygeal teratoma (SCT) is a rare congenital tumour. The risk of malignancy and recurrence are not well defined. Previous studies are small and report differing conclusions about the timing of surgery and the duration of follow-up. We studied the risk of malignant transformation and SCT recurrence after surgery to address these gaps.

METHODS: This was a global retrospective cohort study. Data of consecutive SCT patients was obtained from 145 institutes in 62 countries. Malignant transformation, defined as malignancy at initial resection, malignant recurrence or death due to malignancy, and its risk factors were analysed.

RESULTS: Of the 3612 included …

Case Of An Adolescent Girl With Familial Vulvar Leiomyoma, Madeline Ross, Charlene Dekonenko, Rebecca Rentea, Tazim Dowlut-Mcelroy

Research Days

Background

While uterine leiomyomas remain a common occurrence affecting nearly 30% of adult women above 35yo, leiomyomas can arise anywhere smooth muscle cells are located in the body. Vulvar leiomyomas are a particularly rare diagnosis, often misdiagnosed as Bartholin gland cyst, comprising 0.07% of vulvar tumors, and thought to arise from smooth muscle within the round ligament, erectile tissue, and dartos muscle. Even more rare is the presentation of vulvar leiomyoma in the adolescent population and family history of vulvar leiomyoma.

Case

We present the case of a 16yo girl who noticed a painless vulvar mass that had increased in …

After an initial pull-though, patients with Hirschsprung disease (HD) can present with obstructive symptoms, Hirschsprung-associated enterocolitis (HAEC), failure to thrive, or fecal soiling. This current review focuses on algorithms for evaluation and treatment in children with HD as a part of a manuscript series on updates in bowel management. In constipated patients, anatomic causes of obstruction should be excluded. Once anatomy is confirmed to be normal, laxatives, fiber, osmotic laxatives, or mechanical management can be utilized. Botulinum toxin injections are performed in all patients with HD before age five because of the nonrelaxing sphincters that they learn to overcome with …

Research Days

Background: To lessen surgical times for AIS patients undergoing posterior spinal instrumentation and fusion (PSIF), our department developed a quality improvement initiative where two AIS cases were completed in one day by a specialized team with two surgeons operating together in the same operating room (OR).

Objectives/Goal: We describe the results of this initiative and compare operative times and blood loss between cases to determine if operative time improves as experience with this structure increases.

Methods/Design: From 2017-2023, patients aged 10-18 years with AIS were prospectively scheduled to undergo primary PSIF on the dedicated “Two Spine Tuesday” at our institution. …

Preoperative Srs-22 Scores Predict Postoperative Achievement Of Distribution-Based Mcid In Ais Patients Treated With Posterior Spinal Instrumentation And Fusion, Jonathan Warren, Cyrus Etebari, Morgan Whitmire, Kenneth Furlough, Brant Ansley, John T. Anderson, Richard M. Schwend

Research Days

Background: There is a growing body of literature assessing the role of preoperative patientreported outcome measures in predicting postoperative achievement of the minimal clinically important difference (MCID). To the best of our knowledge, there are no studies assessing whether preoperative SRS-22 scores are predictive of postoperative achievement of MCID in patient with adolescent idiopathic scoliosis (AIS).

Objectives/Goal: Our purpose is to determine if preoperative SRS-22 scores in patients with AIS who undergo posterior spinal instrumentation and fusion can predict postoperative achievement of MCID.

Methods/Design: SRS-22 forms were provided to all patients scheduled to undergo posterior spinal instrumentation and fusion. MCID …

Common Misperceptions Of Child Abuse In Toddler Femur Fractures, Olivia Pruss, Jonathan Warren, Vincent Staggs, Grace Tideman, Collin Erickson, William L. Hennrikus, Richard M. Schwend

Research Days

Background: Current AAOS guidelines recommend that all children younger than thirty-six months with a femur fracture be evaluated for child abuse. However, the chance for abuse in walking-age children is highly unlikely at less than 20%.

Objectives/Goal: The purpose of this study is to identify how a patient’s age and femur fracture morphology impact the likelihood that providers assess a fracture as non-accidental and their decision to pursue further investigation of possible child abuse.

Methods/Design: This was a questionnaire study completed by clinicians from multiple specialties. There were 5 subgroup populations (6, 12, 18, 24, 35 months old) combined with …
