RESUMO
BACKGROUND: Ileocolic intussusception is a common cause of intestinal obstruction in young children. Radiographs may be of limited value in the diagnosis of intussusception and are sometimes utilized primarily to exclude pneumoperitoneum before therapeutic enema reduction. OBJECTIVE: The goal of this study was to determine if radiographic findings in ileocolic intussusception can offer prognostic information regarding the outcome of therapeutic air enema and, for those requiring surgical intervention, surgical outcomes and/or complications. MATERIALS AND METHODS: A single institution retrospective study was performed including all enemas for intussusception performed during a 5-year period from September 2012 to August 2017. Radiographs obtained before therapeutic enema, including our institution radiographs, outside facility radiographs, or scout images obtained during fluoroscopy or computed tomography (CT), were independently scored by two pediatric radiologists for normal bowel gas pattern, soft-tissue mass, paucity of bowel gas, meniscus sign and bowel obstruction. The reviewers were blinded to enema and surgical outcomes at the time of review. Differences were resolved by consensus. Cases were excluded in which there was no adequate pre-procedure radiograph. In total, 182 cases were reviewed. The medical records were reviewed for enema and surgical outcomes. RESULTS: Radiographic findings included normal bowel gas pattern in 13%, soft-tissue mass in 26%, paucity of bowel gas in 65%, meniscus sign in 12% and obstruction in 10% of the cases, with 17.5% of patients having more than one finding. In patients with bowel obstruction on radiographs, there was a statistically significant decrease in success of therapeutic enema (83% vs. 21%, P=0.0001), increase in complicated surgical reductions (47% vs. 4%, P=0.0012), and increase in bowel resection (42% vs. 4%, P=0.003) compared to patients with normal bowel gas pattern. CONCLUSION: Radiographs can offer prognostic information regarding the potential for therapeutic enema success, as well as potential surgical outcomes in patients failing enema reduction. Particularly, bowel obstruction significantly decreases the success of therapeutic enema and increases the need for bowel resection.

BACKGROUND: Hypertrophic pyloric stenosis (HPS) is a common cause of gastric outlet obstruction in young infants. Infants with HPS present with projectile vomiting, sometimes have electrolyte abnormalities and typically undergo pyloromyotomy to alleviate the obstruction. Abdominal US is the gold standard imaging study for diagnosis. Case reports of incidental hepatic portal venous gas have been reported in infants with HPS; however, no large studies have been conducted to determine the incidence or possible clinical implications of this finding. OBJECTIVE: To assess the incidence of portal venous gas in infants with HPS and to determine whether the presence of this gas in infants with HPS indicates a more unstable patient, increased length of stay or worse outcome. MATERIALS AND METHODS: We conducted a retrospective review of sonographic reports containing "pyloric stenosis," excluding negative descriptor, at a tertiary-care children's hospital from November 2010 to September 2017. Data collected included pyloric thickness/length, liver evaluation, portal venous gas, any additional imaging, demographics, symptomatology days, electrolyte abnormality, and length of hospital stay. RESULTS: In a 7-year period, 545 US exams were positive for HPS. Of these, 334 exams included enough hepatic parenchyma to evaluate for portal venous gas. Infants in 6 of the 334 exams demonstrated portal venous gas (1.8%). Clinical presentation (length of symptoms and electrolyte abnormalities), demographics (male predominance and age at presentation) and imaging characteristics (pyloric thickness and length) were similar for the HPS groups with and without portal venous gas. There was no significant difference in outcome or length of hospital stay. CONCLUSION: Visualization of portal venous gas in infants with HPS is not rare and appears benign, without need for further imaging. Portal venous gas in infants with HPS does not portend a more severe patient presentation or outcome.

BACKGROUND: Mucosal healing predicts clinical remission and improved outcomes in patients with Crohn disease (CD). Magnetic resonance enterography (MRE) is a noninvasive imaging modality that can assess small and large bowel wall inflammation. Evidence suggests that MRE may be an acceptable alternative to evaluate mucosal healing over endoscopy. Our objective is to determine whether MRE remission predicts clinical remission at follow-up in children with CD. METHODS: We performed an institutional review board-approved retrospecitve chart review using our prospectively maintained MRE CD database. Inclusion criteria were all children who underwent an MRE more than 6 months after diagnosis with CD who had follow-up of at least 1 year from imaging. RESULTS: A total of 101 children with CD underwent MRE, a median of 1.3 years from diagnosis with a median follow-up of 2.8 years after MRE. Active inflammation was detected in 65 MRE studies, whereas 36 MRE studies demonstrated MRE remission. A total of 88.9% of children demonstrating MRE remission were in clinical remission at follow-up, whereas only 44.6% of those demonstrating MRE active inflammation achieved clinical remission. Children demonstrating MRE-active inflammation were more likely to have a change in medication (44.6% vs 8.3%) and more likely to undergo surgery (18.5% vs 2.8%). CONCLUSIONS: MRE remission is associated with clinical remission at follow-up at least 1 year after MRE. MRE remission was associated with fewer medication changes and fewer surgeries suggesting that, similar to endoscopic remission, MRE remission demonstrates improved outcome. Additional research is needed to confirm that MRE can be used as a surrogate for mucosal healing.

Thoracoschisis is an extremely rare congenital birth defect in which intra-abdominal organs eviscerate through a defect in the thoracic wall(1). There are only seven previously reported pediatric cases and in each case, there is some diaphragmatic anomaly, suggesting that the defect took place before complete formation of the diaphragm. Our patient was referred to us from a local hospital immediately after delivery. The patient was born with a thoracoschisis of the left side below the 8(th) intercostal space. The thoracoschisis was repaired. Although there is a high prevalence of cardiac defects among thoracoschisis patients, this patient shows only small atrial septal defects.

OBJECTIVE: To evaluate rates of intussusception hospitalization among infants in Vietnam before the introduction of rotavirus vaccine. STUDY DESIGN: Between 2009 and 2011, we identified intussusception hospitalizations among infants using the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Clinical Modification code K56.1 at 2 large pediatric hospitals in Ho Chi Minh City, Vietnam that treat most of the intussusception cases in the city. We reviewed all medical records to confirm a Brighton level 1 case definition for intussusception. RESULTS: We identified a total of 869 intussusception cases in Ho Chi Minh City during the 3-year study period, for an annual rate of 296 per 100,000 infants. The mean age of intussusception was â¼ 37 weeks (8.6 months), with <2% of the cases occurring before age 15 weeks. Cases of intussusception were observed year-round in these hospitals with no evident seasonal pattern. Ultrasonography was used to diagnose most cases (97%), and reduction was performed by air enema in >95% of the cases, with only 1% of cases at 1 hospital and 5% at the other hospital requiring surgical intervention. Ultrasound diagnosis was confirmed by an independent radiologist in 94% of a randomly selected group of intussusception cases at 1 of the 2 hospitals. No mortality was reported. CONCLUSION: Vietnam has a substantially higher rate of intussusception in children aged >15 weeks compared with most other regions of the world. Most of our cases were diagnosed by ultrasound, and only a small proportion required surgical intervention with no fatalities, suggesting that the higher rates may be related in part to better and earlier detection of intussusception.

PURPOSE: The appearance of the diaphragmatic curvature and the rib insertion level of the diaphragm on postoperative chest X-ray (CXR) may predict recurrence. Our purpose was to examine the relationship between the curvature of the diaphragm on postoperative CXR and recurrence. METHODS: We performed a retrospective review of left-sided, Bochdalek congenital diaphragmatic hernia (CDH) surgical repairs from 2004 to 2015 at a single institution. We developed a tool to measure the flatness of the diaphragm on postoperative CXR, termed the diaphragmatic curvature index (τ). The primary outcome of interest was recurrence after surgical repair. RESULTS: Of the 127 patients identified, 54% (n = 69) had a primary repair, while 46% (n = 58) required a patch repair. The overall recurrence rate was 21.3% (n = 27). There was no difference in median lateral rib insertion level in patients with and without recurrence or those who had a primary or patch repair. The overall median diaphragmatic curvature index was 6.29 (interquartile range [IQR] 5.30-8.09) and was not significantly different among patients who had a recurrence (6.00, IQR 5.34-8.24) and those who did not (6.46, IQR 5.24-8.07) (P = .853). Within the primary repair group (6.34 versus 6.93, P = .84) and the patch repair group (5.59 versus 6.18, P = .46), the median diaphragmatic curvature index was not different among patients who had a recurrence and those who did not. CONCLUSIONS: A flat appearance of the diaphragm on postoperative CXR as measured by the median diaphragmatic curvature index (τ) is not associated with recurrence. The shape of the diaphragm on CXR after CDH repair may not be predictive of recurrence as previously thought.

OBJECTIVE: Our aim was to implement a standardized US report that included secondary signs of appendicitis (SS) to facilitate accurate diagnosis of appendicitis and decrease the use of computed tomography (CT) and admissions for observation. METHODS: A multidisciplinary team implemented a quality improvement (QI) intervention in the form of a standardized US report and provided stakeholders with monthly feedback. Outcomes including report compliance, CT use, and observation admissions were compared pretemplate and posttemplate. RESULTS: We identified 387 patients in the pretemplate period and 483 patients in the posttemplate period. In the posttemplate period, the reporting of SS increased from 5.4% to 79.5% (p<0.001). Despite lower rates of appendix visualization (43.9% to 32.7%, p<0.001) with US, overall CT use (8.5% vs 7.0%, p=0.41) and the negative appendectomy rate remained stable (1.0% vs 1.0%, p=1.0). CT utilization for patients with an equivocal ultrasound and SS present decreased (36.4% vs 8.9%, p=0.002) and admissions for observations decreased (21.5% vs 15.3%, p=0.02). Test characteristics of RLQ US for appendicitis also improved in the posttemplate period. CONCLUSION: A focused QI initiative led to high compliance rates of utilizing the standardized US report and resulted in lower CT use and fewer admissions for observation. Study of a Diagnostic Test Level of Evidence: 1.

Sternal cleft anomalies are rare. Associated anomalies include pentalogy of Cantrell and posterior fossa abnormalities, hemangiomas, arteriopathy, cardiac anomalies, eye abnormalities, and sternal defects syndrome. There is only a single report of complete sternal cleft, pectus excavatum, and right clavicular hypoplasia in an adult. Thyroid hemiagenesis is also very rare. To our knowledge, this is the first case of complete sternal cleft, pectus deformity, and right clavicular hypoplasia in a child and the first case with right thyroid hemiagenesis.

INTRODUCTION: Ultrasound (US) is the preferred imaging modality for evaluating appendicitis. Our purpose was to determine if including secondary signs (SS) improve diagnostic accuracy in equivocal US studies. METHODS: Retrospective review identified 825 children presenting with concern for appendicitis and with a right lower quadrant (RLQ) US. Regression models identified which SS were associated with appendicitis. Test characteristics were demonstrated. RESULTS: 530 patients (64%) had equivocal US reports. Of 114 (22%) patients with equivocal US undergoing CT, those with SS were more likely to have appendicitis (48.6% vs 14.6%, p<0.001). Of 172 (32%) patients with equivocal US admitted for observation, those with SS were more likely to have appendicitis (61.0% vs 33.6%, p<0.001). SS associated with appendicitis included fluid collection (adjusted odds ratio (OR) 13.3, 95% confidence interval (CI) 2.1-82.8), hyperemia (OR=2.0, 95%CI 1.5-95.5), free fluid (OR=9.8, 95%CI 3.8-25.4), and appendicolith (OR=7.9, 95%CI 1.7-37.2). Wall thickness, bowel peristalsis, and echogenic fat were not associated with appendicitis. Equivocal US that included hyperemia, a fluid collection, or an appendicolith had 96% specificity and 88% accuracy. CONCLUSION: Use of SS in RLQ US assists in the diagnostic accuracy of appendicitis. SS may guide clinicians and reduce unnecessary CT and admissions.
