Outpatient Botulinum Injections for Early Obstructive Symptoms in Patients with Hirschsprung Disease.

INTRODUCTION: Botulinum toxin (BT) injections may play a role in preventing Hirschsprung associated enterocolitis (HAEC) episodes related to internal anal sphincter (IAS dysfunction). Our aim was to determine the association of outpatient BT injections for early obstructive symptoms on the development of HAEC. METHODS: A retrospective review of children who underwent definitive surgery for Hirschsprung disease (HSCR) from July 2010 - July 2020 was performed. The timing from pull-through to first HAEC episode and to first BT injection was recorded. Primary analysis focused on the rate of HAEC episodes and timing between episodes in patients who did and did not receive BT injections. RESULTS: Eighty patients were included. Sixty patients (75%) were male, 15 (19%) were diagnosed with trisomy 21, and 58 (72.5%) had short-segment disease. The median time to pull-through was 150 days (IQR 16, 132). Eight patients (10%) had neither an episode of HAEC or BT injections and were not included in further analysis. Forty-six patients (64%) experienced at least one episode of HAEC, while 64 patients (89%) had at least one outpatient BT injection. Compared to patients who never received BT injections (n = 9) and those who developed HAEC prior to BT injections (n = 35), significantly fewer patients who received BT injections first (n = 28) developed enterocolitis (P < 0.001), with no patient developing more than one HAEC episode. CONCLUSION: Outpatient BT is associated with decreased episodes of HAEC and increased interval between HAEC episodes requiring inpatient treatment. Scheduling outpatient BT injections to manage obstructive symptoms may be beneficial after pull-through for HSCR.

Behind the mask: extended use of surgical masks is not associated with increased risk of surgical site infection.

PURPOSE: COVID-19 has prompted significant policy change, with critical attention to the conservation of personal protective equipment (PPE). An extended surgical mask use policy was implemented at our institution, allowing use of one disposable mask per each individual, per day, for all the cases. We investigate the clinical impact of this policy change and its effect on the rate of 30-day surgical site infection (SSI). METHODS: A single-institution retrospective review was performed for all the elective pediatric general surgery cases performed pre-COVID from August 2019 to October 2019 and under the extended mask use policy from August 2020 to October 2020. Procedure type, SSI within 30 days, and postoperative interventions were recorded. RESULTS: Four hundred and eighty-eight cases were reviewed: 240 in the pre-COVID-19 cohort and 248 in the extended surgical mask use cohort. Three SSIs were identified in the 2019 cohort, and two in the 2020 cohort. All postoperative infections were superficial and resolved within 1 month of diagnosis with oral antibiotics. There were no deep space infections, readmissions, or infections requiring re-operation. CONCLUSION: Extended surgical mask use was not associated with increased SSI in this series of pediatric general surgery cases and may be considered an effective and safe strategy for resource conservation with minimal clinical impact.

IMPPACT (Intravenous Monotherapy for Postoperative Perforated Appendicitis in Children Trial): Randomized Clinical Trial of Monotherapy Versus Multi-drug Antibiotic Therapy.

BACKGROUND: Perforated appendicitis is the most common cause of intraabdominal abscess (IAA) in children. The optimal postoperative antibiotic regimen to reduce IAA has evolved in the last decade from triple-drug to 2-drug therapy (CM). Recent retrospective studies show decreased infectious complications with monotherapy PT. To date prospective comparative data are lacking. Therefore, a prospective randomized trial comparing PT versus CM was conducted. METHODS: A multi-institutional prospective randomized trial was performed in children with perforated appendicitis comparing postoperative antibiotic regimens PT or CM. The primary outcome was 30-day postoperative IAA formation. Perforation was strictly defined as a hole in the appendix or fecalith in the abdomen, documented with intraoperative photographs. RESULTS: One hundred sixty-two patients were enrolled during the study period. No differences in age, weight, or duration of presenting symptoms were identified. In addition, length of stay, duration of intravenous antibiotic treatment, discharge oral antibiotic treatment, and antibiotic-related complications did not differ between groups. Compared to the CM group, the PT group had significantly lower IAA rate [6.1% vs 23.8%, odd ratio (OR) 4.80, P = 0.002], lower postoperative computed tomography imaging rate (13.9% vs 29.3%, OR 2.57, P = 0.030), and fewer emergency room visits (8.8% vs 26.4%, OR 3.73, P = 0.022). Multivariate logistic regression analysis found the use of CM versus PT (OR 9.21, P = 0.021) to be the most significant predictor for developing IAA. CONCLUSIONS: In children with perforated appendicitis, postoperative monotherapy with PT is superior to standard 2-drug therapy with CM and does not increase antibiotic-related complications or antibiotic exposure duration.

Characterization of Pediatric Breast Abscesses and Optimal Treatment: A Retrospective Analysis.

BACKGROUND: Literature on pediatric breast abscesses is sparse; therefore, treatment is based on adult literature which has shifted from incision and drainage (I&D) to needle aspiration. However, children may require different treatment due to different risk factors and the presence of a developing breast bud. We sought to characterize pediatric breast abscesses and compare outcomes. MATERIALS AND METHODS: A retrospective review of patients presenting with a primary breast abscess from January 2008 to December 2018 was conducted. Primary outcome was persistent disease. Antibiotic utilization, treatment required, and risk factors for abscess and recurrence were also assessed. A follow-up survey regarding scarring, deformity, and further procedures was administered. Fisher's exact and Kruskal-Wallis tests for group comparisons and multivariable regression to determine associations with recurrence were performed. RESULTS: Ninety-six patients were included. The median age was 12.8 y [IQR 4.9, 14.3], 81% were women, and 51% were African-American. Most commonly, patients were treated with antibiotics alone (47%), followed by I&D (27%), and aspiration (26%). Twelve patients (13%) had persistent disease. There was no difference in demographic or clinical characteristics between those with persistent disease and those who responded to initial treatment. The success rates of primary treatment were 80% with antibiotics alone, 90% with aspiration, and 96% with I&D (P = 0.35). The median time to follow-up survey was 6.5 y [IQR 4.4, 8.5]. Four patients who underwent I&D initially reported significant scarring. CONCLUSIONS: Treatment modality was not associated with persistent disease. A trial of antibiotics alone may be considered to minimize the risk of breast bud damage and adverse cosmetic outcomes with invasive intervention.

The impact of botulinum injection for hospitalized children with Hirschsprung-associated enterocolitis.

INTRODUCTION: Stasis from obstruction at the level of the internal anal sphincter (IAS) can lead to Hirschsprung-associated enterocolitis (HAEC) and may be improved by botulinum toxin (BT) injections. Our aim was to determine if BT injection during HAEC episodes decreased the number of recurrent HAEC episodes and/or increased the interval between readmissions. METHODS: A retrospective review was performed of patients admitted for HAEC from January 2010 to December 2019. Demographics and outcomes of patients who received BT were compared to patients who did not receive BT during their hospital stay. RESULTS: A total of 120 episodes of HAEC occurred in 40 patients; 30 patients (75%) were male, 7 (18%) had Trisomy 21 and 10 (25%) had long-segment disease. On multivariate analysis, patients who received BT during their inpatient HAEC episode had a longer median time between readmissions (p = 0.04) and trending toward an association with fewer readmissions prior to a follow-up clinic visit (p = 0.08). CONCLUSION: The use of BT in HD patients hospitalized for HAEC is associated with an increased time between recurrent HAEC episodes and trended toward fewer recurrent episodes. The use of BT should be considered in the management of patients admitted with HAEC.

Optimization of Pediatric Bowel Management Using an Antegrade Enema Troubleshooting Algorithm.

BACKGROUND: A successful flush is the ability to flush through the appendicostomy or cecostomy channel, empty the flush through the colon, and achieve fecal cleanliness. We evaluated our experience with patients who were having flush difficulties based on a designed algorithm. METHODS: Eight patients with flush difficulties were initially evaluated. Based on the need for additional surgery versus changes in bowel management therapy (BMT), we developed an algorithm to guide future management. The algorithm divided flush issues into before, during, and after flushing. Children aged <20 y who presented with flush issues from September 2018 to August 2019 were evaluated to determine our algorithm's efficacy. Specific outcomes analyzed included changes in BMT versus need for additional surgery. RESULTS: After algorithm creation, 29 patients were evaluated for flush issues. The median age was 8.4 y (interquartile range: 6, 14); 66% (n = 19) were men. Underlying diagnoses included anorectal malformations (n = 17), functional constipation (n = 7), Hirschsprung's disease (n = 2), spina bifida (n = 2), and prune belly (n = 1). A total of 35 flush issues/complaints were noted: 29% before the flush, 9% during the flush, and 63% after the flush. Eighty percent of issues before the flush required surgical intervention, wherease 92% of issues during or after the flush were managed with changes in BMT. CONCLUSIONS: Most flush issues respond to changes in BMT. This algorithm can help delineate which types of flush issues would benefit from surgical intervention and what problems might be present if patients are not responding to changes in their flush regimen.

Intra-abdominal Abscess After Appendectomy-Are Drains Necessary in All Patients?

BACKGROUND: Research has shown that patients who develop a postoperative intra-abdominal abscess (PIAA) after appendectomy have a greater number of health care visits with drain placement. Our institution developed an algorithm to limit drain placement for only abscesses with a size >20 cm2. We sought to determine the adherence to and effectiveness of this algorithm. METHODS: This prospective observational study included patients aged 2-18 y old who developed a PIAA from September 2017 to June 2019. Outcomes were compared between patients with a small or large abscess. Analysis was performed in STATA; P < 0.05 was significant. RESULTS: Thirty patients were included. The median age was 10.6 y (7, 11.7); 60% were men, and 60% were Caucasian. The median duration of symptoms before diagnosis of appendicitis was 3 d (2, 6). Thirteen patients (43%) were diagnosed with a PIAA while still inpatient, and 17 (57%) were readmitted at a later date. After algorithm implementation, 95% (n = 19) of patients with a large abscess had aspiration ± drain placement, whereas 30% (n = 3) with a small abscess underwent drainage. Length of stay after abscess diagnosis, total duration of antibiotics, and number of health care visits were the same between groups. One patient with a small abscess required reoperation for an obstruction, whereas one patient with a large abscess that was drained was readmitted for a recurrent abscess. CONCLUSIONS: Small PIAA can be successfully managed without intervention. Our proposed algorithm can assist in determining which patients can be treated with antibiotics alone.

Inpatient management of Hirschsprung's associated enterocolitis treatment: the benefits of standardized care.

INTRODUCTION: Patients with Hirschsprung's disease (HSCR) remain at risk of developing Hirschsprung-associated enterocolitis (HAEC) after surgical intervention. As inpatient management remains variable, our institution implemented an algorithm directed at standardizing treatment practices. This study aimed to compare the outcomes of patients pre- and post-algorithm. METHODS: A retrospective review of patients admitted for HAEC was performed; January 2017-June 2018 encompassed the pre-implementation period, and October 2018-October 2019 was the post-implementation period. Demographics and outcomes were compared between the two groups. RESULTS: Sixty-two episodes of HAEC occurred in 27 patients during the entire study period. Sixteen patients (59%) had more than one episode. The most common levels of the transition zone were the rectosigmoid (50%) and descending colon (27%). Following algorithm implementation, the median length of stay (2 vs. 7 days, p < 0.001), TPN duration (0 vs. 5.5 days, p < 0.001), and days to full enteral diet (6 days vs. 2 days, p < 0.001) decreased significantly. Readmission rates for recurrent enterocolitis were similar pre- and post-algorithm implementation. CONCLUSION: The use of a standardized algorithm significantly decreases the length of stay and duration of intravenous antibiotic administration without increasing readmission rates, while still providing appropriate treatment for HAEC. LEVEL OF EVIDENCE: III level. TYPE OF STUDY: Retrospective comparative study.

Does the addition of fundoplication to repair the intra-thoracic stomach improve quality of life?

BACKGROUND: The role of fundoplication in addition to hiatal hernia repair has been controversial. The aim of this study was to compare quality of life related to gastroesophageal reflux disease (GERD) in patients who underwent intra-thoracic stomach repair with and without fundoplication. We proposed that the group without a fundoplication would have poorer quality of life due to continued symptoms. METHODS: All patients undergoing foregut surgery at the Creighton University Esophageal Center are entered in a prospectively maintained database. The database was queried to identify patients who underwent surgery for a near complete (>75 % of stomach in chest) intra-thoracic stomach with gastric volvulus between 2004 and 2013. A questionnaire was derived from the Quality of Life in Reflux and Dyspepsia and Frequency Scale for Symptoms of GERD questionnaires to assess for symptoms related to reflux, and this questionnaire was administered by phone. RESULTS: A total of 150 patients underwent repair of ITS during the study period. A total of 109 patients had ITS repair with fundoplication, while 41 had only ITS repair. Follow-up was available in 54 % of patients in the fundoplication group (median follow-up of 5.2 years) and in 49 % of patients in the non-fundoplication group (median follow-up of 4 years). Significantly, more patients woke up at night (p < 0.01) and found themselves coughing around mealtime (p < 0.01) in the fundoplication group. Patients in the non-fundoplication group had significantly more daytime reflux (p = 0.02). Despite these symptoms, only one patient in the fundoplication group and no patients in the non-fundoplication group admitted that these symptoms were severe enough to severely affect their quality of life. All other patients contacted felt satisfied, and >80 % rated their quality of life as either good or excellent. CONCLUSIONS: We conclude that there is not a significant difference in quality-of-life parameters on long-term follow-up between patients undergoing ITS repair with or without fundoplication.

Esophagogastric Junction Morphology and Distal Esophageal Acid Exposure.

BACKGROUND: The Chicago classification has recently added a morphological subclassification for the esophagogastric junction (EGJ). Our aim was to assess the distal esophageal acid exposure in patients with this new Chicago EGJ-type IIIa and IIIb classification. STUDY DESIGN: From a prospectively collected high-resolution manometry (HRM) database, we identified patients who underwent 24-h pH study between October 2011 and June 2015 and were diagnosed with EGJ-type III based on HRM. Chicago EGJ-type III is defined as the inter-peak nadir pressure ≤gastric pressure and a lower esophageal sphincter (LES)-crural diaphragm (CD) separation >2 cm [IIIa-pressure inversion point (PIP) remains at CD level and IIIb-PIP remains at LES level]. We classified the patients into reflux group [DeMeester score >14.72 or Fraction time pH (<4) > 4.2 %] and non-reflux group based on 24-h pH study. RESULTS: Fifty patients were identified that satisfied the study criteria, of which 37 patients (74 %) were EGJ-type IIIa. In those with EGJ-type IIIb, abdominal LES length (AL) in reflux group was significantly shorter than the non-reflux group (0.8 vs. 1.8, p < 0.05). EGJ-type IIIa patients showed significantly higher value for DeMeester score and Fraction time pH and more often had a positive pH study than EGJ-type IIIb patients (DeMeester score: 26.7 vs. 11.7, p < 0.05; Fraction time pH: 7.9 vs. 2.6, p < 0.05; positive pH study: 81.1 vs. 30.8 %, p < 0.001). Reflux was more common in LES-CD ≥ 3 cm than that in LES-CD < 3 cm (85 vs. 56.7 %, p < 0.05). CONCLUSION: A subset of patients with >2-cm LES-CD separation (type IIIb) maintain a physiological intra-abdominal location of the EGJ and are less likely to have reflux. A LES-CD ≥ 3 cm seems to discern a hiatus hernia of clinical significance.

Utilization of a Single-Site Port as an Adjunct for Multi-Port Robotic-Assisted Surgery in Children.

Introduction: The focused use of a single-site port as an adjunct designed to decrease overall port site number and/or assist with specimen extraction in pediatric robotic surgery has not been fully elucidated. We aimed to describe the feasibility of using the single-site port as an adjunct during multi-port robotic-assisted minimally invasive surgery (RA-MIS). Methods: A single institution retrospective review of pediatric patients who underwent multiport RA-MIS with an adjunctive single-site (SS) port from August 2018 to October 2022 was performed. Demographic, perioperative, and postoperative variables were collected; descriptive analysis was performed. Results: A total of 13 patients were included; 46% were female, and 47% were Caucasian. Median age at surgery was 14.9 years of age (interquartile range [IQR] 10.6, 18); median weight was 61.1 kg (IQR 39.7, 73.6). Eleven patients (85%) underwent splenectomy; 2 patients (15%) underwent adrenalectomy. Four patients had a combined procedure (SS cholecystectomy with multi-port splenectomy [n = 3], multi-port bilateral adrenalectomy [n = 1]). The median total operative time was 197 minutes (IQR 131, 316); median console time was 59 minutes (IQR 40, 126). Two 8 mm robotic ports were utilized for all but 1 patient who required a third 8 mm port. The median length of stay was 2.1 days (IQR 2.0, 3.1). One readmission for fever occurred following a combined cholecystectomy/splenectomy. No hernias or wound infections were identified at the single-site port. Conclusion: Use of a SS port as an adjunct is a feasible option and should be considered for those with splenomegaly or need for combined procedures in different quadrants of the abdomen.

Robotic-assisted Pediatric Thoracic and Abdominal Tumor Resection: An Initial Multi-center Review.

INTRODUCTION: Robotic-assisted minimally invasive surgery (RA-MIS) for tumor resection is an emerging technology in the pediatric population with significant promise but unproven safety and feasibility. METHODS: A multi-center retrospective review of patients ≤18 years undergoing RA-MIS tumor resection from December 2015-March 2023 was performed. Patient demographics, perioperative variables, and complication rates were analyzed. RESULTS: Thirty-nine procedures were performed on 38 patients (17 thoracic, 22 abdominal); 37% female and 68% non-Hispanic White. Median age at surgery was 8.3 years (IQR 5.7, 15.7); the youngest was 1.7 years-old. Thoracic operations included resections of neuroblastic tumors (n = 16) and a single paraganglioma. The most common abdominal operations included resections of neuroblastic tumors (n = 5), pheochromocytomas (n = 3), and angiomyolipomas (n = 3). Six patients underwent retroperitoneal lymph node dissection (RPLND) for paratesticular tumors. Median operating time for the cohort was 2:52 h (IQR 2:04, 4:31). Two thoracic cases required open conversion due to poor visualization and lack of working domain. All patients underwent complete tumor resection; one had tumor spillage from a positive margin (Wilms tumor). Median LOS was 1.5 days (IQR 1.1, 3.0). Postoperatively, one patient developed a chyle leak requiring interventional radiology drainage, but none required a return to the operating room. CONCLUSIONS: Robotic-assisted surgery is safe and feasible for tumor resection in carefully selected pediatric patients, achieving complete resection with minimal morbidity and short LOS. Resection should be performed by those with robotic expertise for optimal outcomes. LEVEL OF EVIDENCE: IV. TYPE OF STUDY: Original Clinical Research.

Pediatric Bowel Management Options and Organizational Aspects.

A bowel management program (BMP) to treat fecal incontinence and severe constipation is utilized for patients with anorectal malformations, Hirschsprung disease, spinal anomalies, and functional constipation, decreasing the rate of emergency department visits, and hospital admissions. This review is part of a manuscript series and focuses on updates in the use of antegrade flushes for bowel management, as well as organizational aspects, collaborative approach, telemedicine, the importance of family education, and one-year outcomes of the bowel management program. Implementation of a multidisciplinary program involving physicians, nurses, advanced practice providers, coordinators, psychologists, and social workers leads to rapid center growth and enhances surgical referrals. Education of the families is crucial for postoperative outcomes, prevention, and early detection of complications, especially Hirschsprung-associated enterocolitis. Telemedicine can be proposed to patients with a defined anatomy and is associated with high parent satisfaction and decreased patient stress in comparison to in-person visits. The BMP has proved to be effective in all groups of colorectal patients at a 1- and 2-year follow-up with social continence achieved in 70-72% and 78% of patients, respectively, and an improvement in the patients' quality of life. A transitional care to adult program is essential to maintain the same quality of care, and continuity of care and to achieve desired long-term outcomes as the patient reaches adult age.

Pre-hospital CPR after traumatic arrest: Outcomes at a level 1 pediatric trauma center.

BACKGROUND: The survival of traumatic cardiopulmonary arrest (TCA) requiring pre-hospital cardiopulmonary resuscitation (P-CPR) is abysmal across age groups. We aim to describe the mechanisms of injury and outcomes of children suffering from TCA leading to P-CPR at our institution. METHODS: A retrospective review was conducted to identify children ages 0-17 years who suffered TCA leading to P-CPR at our institution between 5/2009 and 3/2020. For analysis, patients were stratified into those still undergoing CPR at arrival and those who attained pre-hospital return of spontaneous circulation (ROSC). Primary outcome was discharge alive from the hospital. RESULTS: P-CPR was initiated for 48 patients who had TCA; 23 had pre-hospital ROSC. Of the 25 children undergoing CPR at presentation, none survived to discharge. The median duration of CPR, from initiation to time of death declaration was 34 min [29,50]. Seventeen patients died after resuscitation attempts in the ED, while 8 died after admission to the PICU. Of the 23 patients who attained pre-hospital ROSC, 6 survived to discharge. All survivors required intensive rehabilitation services at discharge and at most recent follow-up, 5 had residual deficits requiring medical attention. CONCLUSION: There are poor outcomes in children with pre-hospital traumatic cardiopulmonary arrest, particularly in those without pre-hospital ROSC. These data further support the need for standardized guidelines for resuscitation in children with traumatic cardiopulmonary arrest.

State of the Art Bowel Management for Pediatric Colorectal Problems: Functional Constipation.

BACKGROUND: Functional constipation (FC) affects up to 32% of the pediatric population, and some of these patients are referred to pediatric surgery units to manage their constipation and/or fecal incontinence. The aim of the current paper is to report the recent updates on the evaluation and management of children with FC as a part of a manuscript series on bowel management in patients with anorectal malformations, Hirschsprung disease, spinal anomalies, and FC. METHODS: A literature search was performed using Medline/PubMed, Google Scholar, Cochrane, and EMBASE databases and focusing on the manuscripts published within the last 5-10 years. RESULTS: The first step of management of children with FC is to exclude Hirschsprung disease with a contrast study, examination under anesthesia, anorectal manometry (AMAN). If AMAN shows absent rectoanal inhibitory reflex, a rectal biopsy is performed. Internal sphincter achalasia or high resting pressures indicate botulinum toxin injection. Medical management options include laxatives, rectal enemas, transanal irrigations, and antegrade flushes. Those who fail conservative treatment require further assessment of colonic motility and can be candidates for colonic resection. The type of resection (subtotal colonic resection vs. Deloyer's procedure) can be guided with a balloon expulsion test. CONCLUSION: Most of the patients with FC referred for surgical evaluation can be managed conservatively. Further studies are required to determine an optimal strategy of surgical resection in children unresponsive to medical treatment.

State of the Art Bowel Management for Pediatric Colorectal Problems: Anorectal Malformations.

Up to 79% of patients with anorectal malformations (ARMs) experience constipation and/or soiling after a primary posterior sagittal anoplasty (PSARP) and are referred to a bowel management program. We aim to report the recent updates in evaluating and managing these patients as part of the manuscript series on the current bowel management protocols for patients with colorectal diseases (ARMs, Hirschsprung disease, functional constipation, and spinal anomalies). The unique anatomic features of ARM patients, such as maldeveloped sphincter complex, impaired anal sensation, and associated spine and sacrum anomalies, indicate their bowel management plan. The evaluation includes an examination under anesthesia and a contrast study to exclude anatomic causes of poor bowel function. The potential for bowel control is discussed with the families based on the ARM index calculated from the quality of the spine and sacrum. The bowel management options include laxatives, rectal enemas, transanal irrigations, and antegrade continence enemas. In ARM patients, stool softeners should be avoided as they can worsen soiling.

Infliximab Rescue Therapy in Pediatric Severe Colitis.

INTRODUCTION: Clinical remission has been achieved with infliximab in patients with refractory ulcerative colitis (UC). However, there is conflicting data regarding its effectiveness as rescue therapy in adult acute severe colitis. Furthermore, pediatric inflammatory bowel disease (IBD) is associated with more severe disease that may be less amenable to attempted rescue. We reviewed our experience and outcomes with pediatric severe colitis after attempted inpatient rescue with infliximab. METHODS: A single-institution, retrospective review was conducted of pediatric patients with UC or indeterminate colitis who received inpatient rescue infliximab therapy from 1/2000 to 1/2019. Rescue infliximab therapy was considered if a child failed non-biologic therapy or progressed to fulminant or toxic colitis. Primary outcome was failed therapy resulting in colectomy. A p-value of <0.05 determined significance. RESULTS: Thirty patients met inclusion criteria. The median age at administration of rescue infliximab treatment was 14 years [IQR 13,17]. Rescue therapy with infliximab was successful in 33% (n = 10), while 67% (n = 20) underwent colectomy. Children on maintenance steroids were less likely to be successfully rescued with infliximab and require colectomy (p = 0.03). Children requiring colectomy had a longer hospital stay (p = 0.03), more abdominal radiographs (p = 0.01), and were on a longer duration of antibiotics (p = <0.01) compared to children who were successfully rescued with infliximab. There was no difference in baseline vital signs or laboratory abnormalities between the two groups. CONCLUSION: In severe acute ulcerative or indeterminate colitis cases where infliximab has not been previously used, rescue infliximab can be used to avoid colectomy but has a high failure rate.

Utilization of an Enhanced Recovery After Surgery (ERAS) protocol for pediatric metabolic and bariatric surgery.

INTRODUCTION: Enhanced recovery after surgery (ERAS) protocols for pediatric metabolic and bariatric surgery are limited. In 2018, an ERAS protocol for patients undergoing robotically assisted vertical sleeve gastrectomy (r-VSG) was instituted. This study's aim was to compare outcomes before and after ERAS initiation. METHODS: A single institution retrospective review of patients undergoing r-VSG from July 2015 to July 2021 was performed. The multimodal ERAS protocol focused on limiting post-operative nausea and narcotic utilization. Subjects were categorized into non-ERAS (July 2015-July 2018) and ERAS (August 2018-July 2021) groups. In-hospital and 30-day outcomes were compared. RESULTS: 110 subjects (94 females) with a median age of 17.6 years (range 12.5-22.0 years) were included (60 non-ERAS, 50 ERAS). Demographics were similar except for a higher proportion of females in the non-ERAS group (97% vs 72%, p < 0.001). A significant decrease in narcotic use (p < 0.001) and higher utilization of acetaminophen (p < 0.001) and ketorolac (p < 0.001) was observed in the ERAS group. Additionally, median time to oral intake, a proxy for postoperative nausea and vomiting [2:00 h (1:15, 2:30) vs. 3:22 h (2:03, 6:15), p < 0.001] and hospital length of stay (LOS) [1.25 days (1.14, 1.34) vs. 2.16 days (1.48, 2.42), p < 0.001] were shorter in the ERAS group. Eleven subjects (10%; ERAS = 5, non-ERAS = 6) experienced post-discharge dehydration, prompting readmission 8 times for 7 (6%) individuals. CONCLUSION: Utilization of ERAS led to a significant decrease narcotic utilization, time to first oral intake, and hospital LOS with no change in adverse events following pediatric metabolic and bariatric surgery. Larger studies, including comparative analysis of health care utilization, should be carried out. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Treatment Study.
