RESUMEN
BACKGROUND: This study aimed to determine whether (1) the propensity for concurrent fundoplication during gastrostomy varies among hospitals, and (2) postoperative morbidity differs among institutions performing fundoplication more or less frequently. METHODS: Children who underwent gastrostomy with or without concurrent fundoplication were identified in the American College of Surgeons National Surgical Quality Improvement Program Pediatric (ACS-NSQIP-P). A hierarchical multivariate regression modeled the excess effects that hospitals exerted over propensity for concurrent fundoplication adjusting for preoperative clinical variables. Hospitals were designated as low outliers (significantly lower-adjusted odds of concurrent fundoplication than the average hospital with similar patient mix), average hospitals, and high outliers based on their risk-adjusted concurrent fundoplication practice. The postoperative morbidity rates were compared among low-outlier, average, and high-outlier hospitals. RESULTS: Between 2011 and 2013, 3775 children underwent gastrostomy at one of 54 ACS-NSQIP-P participating hospitals. The mean hospital concurrent fundoplication rate was 11.7% (range 0-64%). There was no significant difference in unadjusted morbidity rate in children with concurrent fundoplication, 11.0% compared to 9.7% in children without concurrent fundoplication. After controlling for clinical variables, 8 hospitals were identified as low outliers (fundoplication rate of 0.4%) and 16 hospitals were identified as high outliers (fundoplication rate of 34.6%). The average unadjusted morbidity rate among hospitals with low, average, and high odds of concurrent fundoplication were 9.6, 10.6, and 8.4%, respectively. CONCLUSION: Hospitals vary significantly in propensity for concurrent fundoplication during gastrostomy yet postoperative morbidity does not differ significantly among institutions performing fundoplication more or less frequently.

BACKGROUND: Intraoperative and postoperative red blood cell (RBC) transfusions are relatively frequent events tracked in the American College of Surgeons' National Surgical Quality Improvement Program-Pediatric (ACS-NSQIP-P). This study sought to quantify variation in RBC transfusion practices among hospitals. STUDY DESIGN AND METHODS: This is an observational study of children older than 28 days who underwent a general, neurologic, urologic, otolaryngologic, plastic, or orthopedic operation at 50 hospitals in participating in the ACS-NSQIP-P during 2011 to 2012. The primary outcome was whether or not a RBC transfusion was administered from incision time to 72 hours postoperatively. Transfusions of fresh-frozen plasma, cryoprecipitate, and platelets were excluded from data abstraction due the rarity of their administration. A multivariate hierarchical risk-adjustment model estimated the risk-adjusted hospital RBC transfusion odds ratio (OR) and designated hospitals by transfusion practice. RESULTS: The mean RBC transfusion rate was 1.5%. Five preoperative variables were associated with greater than threefold increased odds of having an intraoperative or postoperative RBC transfusion; young age; 29 days to 1 year (OR, 5.9; p < 0.001) and 1 to 2 years (OR, 3.4; p < 0.001); American Society of Anesthesiologists Class IV (OR, 3.2; p < 0.001); procedure linear risk (OR, 3.1; p < 0.001); preoperative septic shock (OR, 14.5; p < 0.001); and preoperative cardiopulmonary resuscitation (OR, 8.1; p < 0.001). Twenty-five hospitals had RBC transfusion practices significantly different than risk-adjusted mean (17 higher and eight lower). CONCLUSION: Intraoperative and postoperative RBC transfusion practices vary widely among hospitals after controlling for patient and procedural characteristics.

Necrotizing enterocolitis (NEC) remains a significant cause of morbidity and mortality in premature neonates. Despite decades of investigation, treating clinicians are still not able to determine which premature infants are at greatest risk of developing NEC and which of the affected infants will develop severe NEC requiring operation. A biomarker is a specific molecular indicator that can be used to identify or measure the progress of a disease. Many potential biomarkers have been studied for their potential relevance to NEC. Those showing promise include C-reactive protein, intestinal fatty acid-binding protein, platelet-activating factor and many others. None to date have achieved sufficient predictive value to be clinically useful. Distinguishing between the specific changes in NEC and the non-specific inflammation of sepsis has proven challenging. Urine is a particularly attractive site for potential biomarkers. It can be collected readily and non-invasively, and it is a rich source of both proteins and peptides. Preliminary work has revealed some promising biomarkers of NEC in urine. Combined with clinical data, they have been shown to be highly predictive in small series of patients. Advances in high-throughput molecular analysis have opened the door to finding biomarkers that may meaningfully improve the outcome of infants at risk for NEC.

OBJECTIVE: Necrotising enterocolitis (NEC) is a major source of neonatal morbidity and mortality. The management of infants with NEC is currently complicated by our inability to accurately identify those at risk for progression of disease prior to the development of irreversible intestinal necrosis. We hypothesised that integrated analysis of clinical parameters in combination with urine peptide biomarkers would lead to improved prognostic accuracy in the NEC population. DESIGN: Infants under suspicion of having NEC (n=550) were prospectively enrolled from a consortium consisting of eight university-based paediatric teaching hospitals. Twenty-seven clinical parameters were used to construct a multivariate predictor of NEC progression. Liquid chromatography/mass spectrometry was used to profile the urine peptidomes from a subset of this population (n=65) to discover novel biomarkers of NEC progression. An ensemble model for the prediction of disease progression was then created using clinical and biomarker data. RESULTS: The use of clinical parameters alone resulted in a receiver-operator characteristic curve with an area under the curve of 0.817 and left 40.1% of all patients in an 'indeterminate' risk group. Three validated urine peptide biomarkers (fibrinogen peptides: FGA1826, FGA1883 and FGA2659) produced a receiver-operator characteristic area under the curve of 0.856. The integration of clinical parameters with urine biomarkers in an ensemble model resulted in the correct prediction of NEC outcomes in all cases tested. CONCLUSIONS: Ensemble modelling combining clinical parameters with biomarker analysis dramatically improves our ability to identify the population at risk for developing progressive NEC.

OBJECTIVES: To test the hypothesis that an exploratory proteomics analysis of urine proteins with subsequent development of validated urine biomarker panels would produce molecular classifiers for both the diagnosis and prognosis of infants with necrotizing enterocolitis (NEC). STUDY DESIGN: Urine samples were collected from 119 premature infants (85 NEC, 17 sepsis, 17 control) at the time of initial clinical concern for disease. The urine from 59 infants was used for candidate biomarker discovery by liquid chromatography/mass spectrometry. The remaining 60 samples were subject to enzyme-linked immunosorbent assay for quantitative biomarker validation. RESULTS: A panel of 7 biomarkers (alpha-2-macroglobulin-like protein 1, cluster of differentiation protein 14, cystatin 3, fibrinogen alpha chain, pigment epithelium-derived factor, retinol binding protein 4, and vasolin) was identified by liquid chromatography/mass spectrometry and subsequently validated by enzyme-linked immunosorbent assay. These proteins were consistently found to be either up- or down-regulated depending on the presence, absence, or severity of disease. Biomarker panel validation resulted in a receiver-operator characteristic area under the curve of 98.2% for NEC vs sepsis and an area under the curve of 98.4% for medical NEC vs surgical NEC. CONCLUSIONS: We identified 7 urine proteins capable of providing highly accurate diagnostic and prognostic information for infants with suspected NEC. This work represents a novel approach to improving the efficiency with which we diagnose early NEC and identify those at risk for developing severe, or surgical, disease.

Necrotizing enterocolitis (NEC) is the most common surgical emergency occurring in neonatal intensive care unit (NICU) patients. Among patients with NEC, those that require surgery experience the poorest outcomes and highest mortality. Surgical intervention, while attempting to address the intestinal injury and ongoing mulitfactorial physiologic insults in NEC is associated with its own stresses that may compound the ongoing physiologic derangement. Surgery is thus reserved for those patients with clear indication for intervention such as pneumoperitoneum, confirmed stool or pus in the peritoneal cavity, or worsening clinical status. The purpose of this review is to briefly describe the physiologic stress induced by surgical intervention in the preterm, low birth weight patient with NEC and to provide a contemporary overview of available surgical management options for NEC. The optimal surgical plan employed is strongly influenced by clinical judgment and theoretical benefits in terms of minimizing physiologic stressors while providing temporary and/or definitive treatment in a timely fashion. While the choice of operation has not been shown to have a significant effect on any clinically important outcomes, ongoing investigations continue to study both short and long-term outcomes in patients with NEC.
RESUMEN
BACKGROUND: The aim of this study was to evaluate a cohort of children undergoing imaging prior to appendectomy in order to identify factors that were associated with undergoing computed tomography (CT) alone as compared to ultrasound (US) alone or US and CT. MATERIALS AND METHODS: The Kids' Inpatient Database was queried for children 1-18 y of age with imaging reported. Logistic regression models identified factors associated with CT-alone imaging modality. RESULTS: There were 6519 patients (69.5%) who underwent CT alone, 2076 (22.1%) who underwent US alone, and 782 (8.4%) who underwent US and CT. The negative appendectomy rates were higher for US alone (6.5%) and US and CT (6.6%) compared to the CT alone group (3.6%, P < 0.001). The perforated appendicitis rates were highest for the US and CT group (36.3%) compared to the CT alone group (31.8%) and the US alone group (29.8%, P = 0.004). Older patients were more likely to undergo CT alone compared to younger patients (odds ratio [OR] 1.44, 95% confidence interval [CI] 1.26-1.64). Girls were less likely to undergo CT alone compared to boys (OR 0.51, 95% CI 0.46-0.56). Hospital factors associated with lower CT-alone imaging included children's centers (OR 0.46, 95% CI 0.41-0.52), teaching hospitals (OR 0.53, 95% CI 0.48-0.60), and urban location (OR 0.40, 95% CI 0.32-0.49). CONCLUSIONS: Though patient factors such as age and sex influence imaging use, children's centers are associated with lower CT-alone imaging compared to non-children's centers. As focus increases on limiting CT use in children, opportunities for improvement based on hospital factors exist.

BACKGROUND: Barriers in access to pediatric surgical care are common in low- and middle-income countries (LMICs), but also exist in high-income countries, particularly in urban and rural areas. METHODS: This article describes "Disparities in Access to Care"-held within the Social Injustice Symposium at the 2020 American Pediatric Surgical Association (APSA) Annual Meeting. RESULTS: This symposium outlined disparities in access to care, illustrated by examples from pediatric trauma and neonatal surgery in U.S. urban, U.S. rural, and non-U.S. global locations (LMICs). Geographic and financial challenges were common to families from the rural U.S. and LMICs. In contrast, families in U.S. urban settings generally do not face geographic barriers, but are often economically and racially diverse and many face complex societal factors leading to poor outcomes. Systemic processes must be changed to improve pediatric surgical health outcomes. CONCLUSION: A comprehensive health system with an equal emphasis on supportive care and surgery is required in all settings. Global collaboration and partnerships can provide an avenue for advocacy and strategic innovation to improve quality of care. LEVEL OF EVIDENCE: â ¤.

Necrotizing enterocolitis (NEC) remains a major cause of neonatal morbidity and death. The pathophysiology is poorly understood. Prevailing evidence suggests that NEC is due to an inappropriate inflammatory response of the immature gut to some undefined insult. The mortality rate (15%-25%) for affected infants has not changed appreciably in 30 years. Many infants with NEC recover uneventfully with medical therapy and have long-term outcomes similar to unaffected infants of matched gestational age. Infants with progressive disease requiring surgical intervention suffer almost all of the mortality and morbidity. Of these, approximately 30%-40% will die of their disease and most of the remainder will develop long-term neurodevelopmental and gastrointestinal morbidity. Recent randomized trials suggest that the choice of operation does not influence patient outcome. Current work is focusing on developing a better understanding of the pathogenesis and improving means to identify which infants are at greatest risk of disease progression.

OBJECTIVE: To determine whether pulmonary function decreases as a function of severity of pectus excavatum, and whether reduced function is restrictive or obstructive in nature in a large multicenter study. STUDY DESIGN: We evaluated preoperative spirometry data in 310 patients and lung volumes in 218 patients aged 6 to 21 years at 11 North American centers. We modeled the impact of the severity of deformity (based on the Haller index) on pulmonary function. RESULTS: The percentages of patients with abnormal forced vital capacity (FVC), forced expiratory volume in 1 second (FEV(1)), forced expiratory flow from 25% exhalation to 75% exhalation, and total lung capacity findings increased with increasing Haller index score. Less than 2% of patients demonstrated an obstructive pattern (FEV(1)/FVC <67%), and 14.5% demonstrated a restrictive pattern (FVC and FEV(1) <80% predicted; FEV(1)/FVC >80%). Patients with a Haller index of 7 are >4 times more likely to have an FVC of ≤80% than those with a Haller index of 4, and are also 4 times more likely to exhibit a restrictive pulmonary pattern. CONCLUSIONS: Among patients presenting for surgical repair of pectus excavatum, those with more severe deformities have a much higher likelihood of decreased pulmonary function with a restrictive pulmonary pattern.

OBJECTIVE: The aim of the study was to prospectively determine risk factors for the development of parenteral nutrition-associated liver disease (PNALD) in infants who underwent surgery for necrotizing enterocolitis (NEC), the most common cause of intestinal failure in children. PATIENTS AND METHODS: : From February 2004 to February 2007, we diagnosed 464 infants with NEC, of whom 180 had surgery. One hundred twenty-seven patients were available for full analysis. PNALD was defined as serum direct bilirubin ≥ 2 mg/dL or ALT ≥ 2 × the upper limit of normal in the absence of sepsis after ≥ 14 days of exposure to PN. RESULTS: Median gestational age was 26 weeks and 68% were boys. Seventy percent of the cohort developed PNALD and the incidence of PNALD varied significantly across the 6 study sites, ranging from 56% to 85% (P = 0.05). Multivariable logistic regression analysis identified small-bowel resection or creation of jejunostomy (odds ratio [OR] 4.96, 95% confidence interval [CI] 1.97-12.51, P = 0.0007) and duration of PN in weeks (OR 2.37, 95% CI 1.56-3.60, P < 0.0001) as independent risk factors for PNALD. Preoperative exposure to PN was also associated with the development of PNALD; the risk of PNALD was 2.6 (95% CI 1.5-4.7; P = 0.001) times greater in patients with ≥ 4 weeks of preoperative PN compared with those with less preoperative PN use. Breast milk feedings, episodes of infection, and gestational age were not related to the development of PNALD. CONCLUSIONS: The incidence of PNALD is high in infants with NEC undergoing surgical treatment. Risk factors for PNALD are related to signs of NEC severity, including the need for small-bowel resection or proximal jejunostomy, as well as longer exposure to PN. Identification of these and other risk factors can help in the design of clinical trials for the prevention and treatment of PNALD and for clinical assessment of patients with NEC and prolonged PN dependence.

OBJECTIVE: To determine risk factors for intestinal failure (IF) in infants undergoing surgery for necrotizing enterocolitis (NEC). STUDY DESIGN: Infants were enrolled in a multicenter prospective cohort study. IF was defined as the requirement for parenteral nutrition for >or= 90 days. Logistic regression was used to identify predictors of IF. RESULTS: Among 473 patients enrolled, 129 had surgery and had adequate follow-up data, and of these patients, 54 (42%) developed IF. Of the 265 patients who did not require surgery, 6 (2%) developed IF (OR 31.1, 95% CI, 12.9 - 75.1, P < .001). Multivariate analysis identified the following risk factors for IF: use of parenteral antibiotics on the day of NEC diagnosis (OR = 16.61, P = .022); birth weight < 750 grams, (OR = 9.09, P < .001); requirement for mechanical ventilation on the day of NEC diagnosis (OR = 6.16, P = .009); exposure to enteral feeding before NEC diagnosis (OR=4.05, P = .048); and percentage of small bowel resected (OR = 1.85 per 10 percentage point greater resection, P = .031). CONCLUSION: The incidence of IF among infants undergoing surgical treatment for NEC is high. Variables characteristic of severe NEC (low birth weight, antibiotic use, ventilator use, and greater extent of bowel resection) were associated with the development of IF.

BACKGROUND: Perforated necrotizing enterocolitis is a major cause of morbidity and mortality in premature infants, and the optimal treatment is uncertain. We designed this multicenter randomized trial to compare outcomes of primary peritoneal drainage with laparotomy and bowel resection in preterm infants with perforated necrotizing enterocolitis. METHODS: We randomly assigned 117 preterm infants (delivered before 34 weeks of gestation) with birth weights less than 1500 g and perforated necrotizing enterocolitis at 15 pediatric centers to undergo primary peritoneal drainage or laparotomy with bowel resection. Postoperative care was standardized. The primary outcome was survival at 90 days postoperatively. Secondary outcomes included dependence on parenteral nutrition 90 days postoperatively and length of hospital stay. RESULTS: At 90 days postoperatively, 19 of 55 infants assigned to primary peritoneal drainage had died (34.5 percent), as compared with 22 of 62 infants assigned to laparotomy (35.5 percent, P=0.92). The percentages of infants who depended on total parenteral nutrition were 17 of 36 (47.2 percent) in the peritoneal-drainage group and 16 of 40 (40.0 percent) in the laparotomy group (P=0.53). The mean (+/-SD) length of hospitalization for the 76 infants who were alive 90 days after operation was similar in the primary peritoneal-drainage and laparotomy groups (126+/-58 days and 116+/-56 days, respectively; P=0.43). Subgroup analyses stratified according to the presence or absence of radiographic evidence of extensive necrotizing enterocolitis (pneumatosis intestinalis), gestational age of less than 25 weeks, and serum pH less than 7.30 at presentation showed no significant advantage of either treatment in any group. CONCLUSIONS: The type of operation performed for perforated necrotizing enterocolitis does not influence survival or other clinically important early outcomes in preterm infants.

Necrotizing enterocolitis (NEC) remains a major cause of morbidity and death in neonates. The 30% to 50% mortality rate for NEC with perforation has not changed appreciably in the past 30 years. The critical relevant outcomes following NEC include survival, gastrointestinal function, and neurodevelopmental status. In each of these areas, initial anecdotal and case-series analysis has been followed by studies using more sophisticated methods of analysis. The single most important predictor of outcome, besides gestational age, is whether or not the disease has progressed to the point requiring surgical intervention. Patients with NEC requiring operation have a high mortality. Moreover, the vast majority of morbidity following NEC occurs in the patients who survive following operation. The purpose of this review is to examine the evolution of evidence regarding outcomes for patients with NEC and to provide an update on our current state of knowledge.

OBJECTIVE: WHO uses anthropometric classification scheme of childhood acute and chronic malnutrition based on low body mass index (BMI) ('wasting') and height for age ('stunting'), respectively. The goal of this study was to describe a novel two-axis nutritional classification scheme to (1) characterise nutritional profiles in children undergoing abdominal surgery and (2) characterise relationships between preoperative nutritional status and postoperative morbidity. DESIGN: This was a retrospective observational cohort study. SETTING: The setting was 50 hospitals caring for children in North America that participated in the American College of Surgeons National Surgical Quality Improvement Program Paediatric from 2011 to 2013. PARTICIPANTS: Children >28 days who underwent major abdominal operations were identified. INTERVENTIONS/MAIN PREDICTOR: The cohort of children was divided into five nutritional profile groups based on both BMI and height for age Z-scores: (1) underweight/short, (2) underweight/tall, (3) overweight/short, (4) overweight/tall and (5) non-outliers (controls). MAIN OUTCOME MEASURES: Multiple variable logistic regressions were used to quantify the association between 30-day morbidity and nutritional profile groups while adjusting for procedure case mix, age and American Society of Anaesthesiologists class. RESULTS: A total of 39 520 cases distributed as follows: underweight/short (656, 2.2%); underweight/tall (252, 0.8%); overweight/short (733, 2.4%) and overweight/tall (1534, 5.1%). Regression analyses revealed increased adjusted odds of composite morbidity (35%) and reintervention events (75%) in the underweight/short group, while overweight/short patients had increased adjusted odds of composite morbidity and healthcare-associated infections (43%), and reintervention events (79%) compared with controls. CONCLUSION: Stratification of preoperative nutritional status using a scheme incorporating both BMI and height for age is feasible. Further research is needed to validate this nutritional risk classification scheme for other surgical procedures in children.
RESUMEN
HYPOTHESIS: The morbidity following treatment for perforated appendicitis in children is significant, with intra-abdominal abscess being one of the more serious complications. This can lead to prolonged hospitalizations and antibiotic administration, multiple computed tomographic scans, and invasive procedures. The purpose of our study was to determine risk factors for developing an intra-abdominal abscess following treatment for perforated appendicitis. DESIGN: Case-control study. SETTING: Four tertiary care children's hospitals. PATIENTS: Children aged 1 to 18 years with appendicitis. INTERVENTION: Multivariable logistic regression. MAIN OUTCOME MEASURES: Development of postoperative abscess, length of hospital stay, presence or absence of fever, and tolerance of diet on postoperative day 3. RESULTS: Thirty-five (13.2%) of 265 children developed an abscess. Ten factors with a bivariate P value <.20 were included in the regression model. The final multivariable model revealed only 2 factors influencing abscess development: an intraoperative fecalith (odds ratio, 8.77 [95% confidence interval, 1.50-51.40]) and diarrhea at presentation. Many factors proposed to be associated with abscess were not, including pain history, type and timing of preoperative antibiotics, abscess at operation, laparoscopic procedure, and length of antibiotics postoperatively. Thiry-seven children were discharged on or before postoperative day 3. Another 21 children were afebrile and tolerating a diet at that time but remained in the hospital. There were no significant differences between the 2 groups. None of the early-discharge group developed an abscess, and 2 of those remaining in the hospital developed an abscess (P = .06). CONCLUSIONS: Clinical factors commonly thought to be predictive of abscess formation following perforated appendicitis were not reliable predictors of this outcome. Our results suggest that if children are afebrile and eating on postoperative day 3 they can be discharged with a low rate of abscess development.

BACKGROUND: Given widespread adoption of the Nuss procedure, prospective multicenter study of management of pectus excavatum by both the open and Nuss procedures was thought desirable. Although surgical repair has been performed for more than 50 years, there are no prospective multicenter studies of its management. STUDY DESIGN: This observational study followed pectus excavatum patients treated surgically at 11 centers in North America, according to the method of choice of the patient and surgeon. Before operation, all underwent evaluation with CT scan, pulmonary function tests, and body image survey. Data were collected about associated conditions, hospital complications, and perioperative pain. One year after completion of treatment, patients will repeat the preoperative evaluations. This article addresses early results only. RESULTS: Of 416 patients screened, 327 were enrolled; 284 underwent the Nuss procedure and 43 had the open procedure. Median preoperative CT index was 4.4. Pulmonary function testing before operation showed mean forced vital capacity of 90% of predicted values; forced expiratory volume in 1 second (FEV(1)), 89% of predicted; and forced expiratory flow during the middle half of the forced vital capacity (FEF(25% to 75%)), 85% of predicted. Early postcorrection results showed that operations were performed without mortality and with minimal morbidity at 30 days postoperatively. Median hospital stay was 4 days. Postoperative pain was a median of 3 on a scale of 10 at time of discharge; the worst pain experienced was the same as was expected by the patients (median 8), and by 30 days after correction or operation, the median pain score was 1. Because of disproportionate enrollment and similar early complication rates, statistical comparison between operation types was limited. CONCLUSIONS: Anatomically severe pectus excavatum is associated with abnormal pulmonary function. Initial operative correction performed at a variety of centers can be completed safely. Perioperative pain is successfully managed by current techniques.

BACKGROUND: Single visit surgery (SVS) consists of same-day pre-operative assessment and operation with telephone post-operative follow-up. This reduces family time commitment to 1 hospital trip rather than 2-3. We began SVS for ambulatory patients with clear surgical indications in 2013. We sought to determine family satisfaction, cost savings to families, and institutional financial feasibility of SVS. METHODS: SVS patients were compared to age/case matched conventional surgery (CS) patients. Satisfaction was assessed by post-operative telephone survey. Family costs were calculated as the sum of lost revenue (based on median income) and transportation costs ($0.50/mile). RESULTS: Satisfaction was high in both groups (98% for SVS vs. 93% for CS; p=0.27). 40% of CS families indicated that they would have preferred SVS, whereas no SVS families indicated preference for the CS option (p<0.001). Distance from the hospital did not correlate with satisfaction. Estimated cost savings for an SVS family was $188. Reimbursement, hospital and physician charges, and day-of-surgery cancellation rates were similar. CONCLUSIONS: SVS provides substantial cost savings to families while maintaining patient satisfaction and equivalent institutional reimbursement. SVS is an effective approach to low-risk ambulatory surgical procedures that is less disruptive to families, facilitates access to pediatric surgical care, and reduces resource utilization. TYPE OF STUDY: Cost Effectiveness Study. LEVEL OF EVIDENCE: Level II.
RESUMEN
We describe a 4-year-old girl who developed a duodenal hematoma after upper endoscopy and biopsy. Although rare, duodenal hematoma formation can occur after upper endoscopy and biopsy in otherwise healthy children. A young child presenting with a duodenal hematoma in the absence of a clear mechanism of either previous gastrointestinal procedures or injury to the abdomen should have an extensive evaluation to exclude child abuse. A thorough evaluation for other medical causes, such as a coagulopathy, should be performed simultaneously.

OBJECTIVE: Gastrostomy feeding tube placement in children is associated with a high frequency of adverse events. This study sought to preoperatively estimate postoperative adverse events in children undergoing gastrostomy feeding tube placement. METHODS: This was an observational study of children who underwent gastrostomy with or without fundoplication at 1 of 50 participating hospitals, using 2011-2013 data from the American College of Surgeons' National Surgical Quality Improvement Program Pediatric. The outcome was the occurrence of any postoperative complications or mortality at 30 days after gastrostomy tube placement. The preoperative clinical characteristics significantly associated with occurrence of adverse events were included in a multivariate logistic model. The area under the receiver operating characteristic curve was computed to assess model performance and split-set validated. RESULTS: A total of 2817 children were identified as having undergone gastrostomy tube placement. The unadjusted rate of adverse events within 30 days after gastrostomy tube placement was 11%. Thirteen predictor variables were identified. Notable preoperative variables associated with a greater than 75% increase in adverse event rate were preoperative sepsis/septic shock (odds ratio [OR], 10.76, 95% confidence interval [CI], 3.84-30.17), central nervous system tumor (OR, 3.36; 95% CI, 1.42-7.95), the primary procedure as indicated by the current procedural terminology (CPT) linear risk variable (OR, 1.93; 95% CI, 1.50-2.49), severe cardiac risk factors (OR, 1.88; 95% CI, 1.17-3.03), and preoperative seizure history (OR, 1.90; 95% CI, 1.38-2.62). The area under the receiver operating characteristic curve was 0.71 with the derivation data set and 0.71 upon split-set validation. CONCLUSIONS: Preoperatively estimating postoperative adverse events in children undergoing gastrostomy tube placement is feasible.
