Neonatal Gastrointestinal Emergencies: A Radiological Review. Arch Pediatr 2022; 29:159-170. [PMID: 35249799 PMCID: PMC8976780 DOI: 10.1016/j.arcped.2022.01.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 12/10/2021] [Accepted: 01/30/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND Abdominal emergencies in neonates require surgical management in almost all cases and complications may include bowel perforation, sepsis, shock, and even death. Radiological imaging has become a very important aid in the clinical setting as it shortens time to diagnosis. OBJECTIVE The objective of this review is to discuss the more prevalent neonatal gastrointestinal emergencies, review appropriate imaging options, and illustrate common radiological presentations of these entities. CONCLUSION Despite advancements in imaging techniques, it is important to keep in mind that neonates have a higher susceptibility to the adverse effects of ionizing radiation, and therefore radiography and ultrasonography remain the main diagnostic modalities for ruling out the diseases with the worst prognosis. Other modalities (fluoroscopy, computed tomography, and magnetic resonance imaging) may have limited use in very specific conditions. All providers in an emergency department should be familiar with the basic radiological findings that may indicate a gastrointestinal emergency, especially in health institutions that do not have 24-h radiologist coverage.

Abstract
AIM As imaging is used for various reasons in children with acute gastrointestinal complaints, we evaluated the indications and diagnostic yield of abdominal imaging, particularly ultrasound at emergency department (ED). METHODS Indications and imaging reports of consecutive children who had undergone abdominal imaging in general, surgical and paediatric EDs in the Tampere University Hospital, Finland, in 2015 were collected. Symptoms, clinical findings, imaging indications and findings were categorised and further analysed. RESULTS Altogether 394 imaging studies, 310 ultrasounds, 72 X-rays and 12 computed tomographies (CT), for 348 children (55% boys) aged 0-16.9 years, median 7.1 years, were performed. The most common indications for ultrasound were suspected appendicitis or infection (36%) and explanation for symptoms (32%), for X-ray suspected foreign body (39%) and obstruction (39%) and for CT trauma (50%). The cause of the symptoms or a clinically significant finding was established in 23% of ultrasounds, varying from 0% to 50% depending on the indication, symptoms and age. CONCLUSION There was wide variation in the indications and yield of abdominal imaging. The clinical benefits, particularly those of US, were often questionable, even leading to delayed diagnosis and complications. More uniform imaging guidelines are needed in the paediatric ED.

Abstract
OBJECTIVES We hypothesized that point-of-care ultrasound (POCUS) is as accurate as radiology-performed ultrasound in evaluating children with clinical concern for appendicitis. As part of a staged approach, we further hypothesized that POCUS could ultimately decrease computed tomography (CT) utilization. METHODS This was a prospective, convenience sampling of patients aged 2 to 18 years presenting with abdominal pain to a pediatric emergency department. Those patients with prior abdominal imaging, pregnant, or unable to tolerate the examination were excluded. An algorithm was followed: POCUS was first performed, followed by a radiology-performed ultrasound, and then a CT as necessary. The main outcome measure was the accuracy of the POCUS in diagnosing of appendicitis. This was compared with radiology-performed ultrasound. We also examined whether certain patient or clinical characteristics influenced the performance of POCUS. Lastly, we determined the amount by which CT scans were decreased through this staged algorithm. RESULTS Forty patients were enrolled and underwent a POCUS examination. A total of 16 (40%) had pathology-confirmed appendicitis. Point-of-care ultrasound had a sensitivity of 93.8% (95% confidence interval [CI], 69.7%-98.9%) and specificity of 87.5% (95% CI, 67.6%-97.2%). Radiology-performed ultrasound had a sensitivity of 81.25% (95% CI, 54.3%-95.7%) and specificity of 100% (95% CI, 85.6%-100%). The radiology-performed and POCUS examinations had very good agreement (κ = 0.83, P < 0.0005). Patient characteristics including body mass index did not have an affect on the POCUS. However, POCUS identified all patients with an Alvarado score higher than 6. Overall, the reduction in CT examinations was 55%. CONCLUSIONS In pediatric patients presenting with clinical concern for acute appendicitis, a staged algorithm that incorporates POCUS is accurate and has the potential to decrease CT scan utilization.

Abstract
We present two cases of pediatric patients initially presenting with a clinical suspicion of acute appendicitis. In these cases, point-of-care ultrasonography was performed early in the patient's emergency department course, leading to alternate diagnoses. This article highlights a role for point-of-care ultrasound in the diagnoses of two alternate conditions that clinically mimic appendicitis: Meckel diverticulitis and acute ileocecitis. We offer a brief overview of terminology, relevant literature, and ultrasound scanning technique for the right-lower-quadrant point-of-care ultrasound evaluation.

Abstract
Intra-abdominal cystic lymphangiomas are rare, benign congenital tumors that often present with vague symptoms, making diagnosis difficult. We report a case of a 4-year-old patient who presented to the emergency department with nonspecific abdominal pain. Her diagnosis of intra-abdominal cystic lymphangioma was facilitated by point-of-care ultrasonography.

Abstract
The diagnosis of acute right lower quadrant pain in a pediatric population is challenging. Acute appendicitis is the most common cause of an acute surgical abdomen. The common mimics of acute appendicitis are acute gastrointestinal and gynecologic diseases. This article reviews the sonographic findings of the spectrum of common acute abdominal emergencies in children with a focus on imaging clues to a specific diagnosis. This awareness can impact on diagnostic accuracy and impact patient management.

Abstract
STUDY OBJECTIVE We investigate the accuracy of pediatric emergency physician sonography for acute appendicitis in children. METHODS We prospectively enrolled children requiring surgical or radiology consultation for suspected acute appendicitis at an urban pediatric emergency department. Pediatric emergency physicians performed focused right lower-quadrant sonography after didactics and hands-on training with a structured scanning algorithm, including the graded-compression technique. We compared their sonographic interpretations with clinical and radiologic findings, as well as clinical outcomes as defined by follow-up or pathologic findings. RESULTS Thirteen pediatric emergency medicine sonographers performed 264 ultrasonographic studies, including 85 (32%) in children with pathology-verified appendicitis. Bedside sonography had a sensitivity of 85% (95% confidence interval [CI] 75% to 95%), specificity of 93% (95% CI 85% to 100%), positive likelihood ratio of 11.7 (95% CI 6.9 to 20), and negative likelihood ratio of 0.17 (95% CI 0.1 to 0.28). CONCLUSION With focused ultrasonographic training, pediatric emergency physicians can diagnose acute appendicitis with substantial accuracy.

Abstract
Objective To investigate clinical features of infantile hypertrophic pyloric stenosis (IHPS) in Chinese Han population. Methods Three hundred and sixteen hospitalized patients with IHPS from January 1998 to February 2010 were retrospectively reviewed, and data including patient's sex, onset age, other coexisting congenital defects, pyloric circular muscle thickness evaluated by ultrasonograph, serum electrolytes concentration, and results of arterial blood gas analysis on admission were collected. The patients were divided into two groups: the duration between first onset and admission less than or equal to 10 days (early onset group), and more than 10 days (late onset group). The results of arterial blood gas and serum electrolyte concentration were compared between the two groups. Results There were 271 males and 45 females in 316 patients; the onset age ranged between 1 and 351 (26.5±26.6) days. The birth weight ranged between 1.6 and 4.5 (3.23±0.44) kilograms; coexisting congenital defects were found in 65 cases (20.6%). Pyloric circular muscle thickness was 4–8 (5.4±1.0) millimetres (mm). For the early onset group, the rates of hypokalemia, hypochloraemia and hypercapnia were significantly lower than those in the late onset group (18.67% VS 50%, P<0.0001; 46.03% VS 71.01%, P = 0.003; 56.58% VS 83.44%, P = 2.17×10−5; respectively). Conclusions The symptom duration in Chinese Han population was longer than that in other populations. And as the prolongation of symptom duration, the incidence of acid-base imbalance increased significantly. Infants with persistent vomiting at the age of 3∼5 weeks after birth should be considered IHPS, and go to hospital as soon as possible in order to reduce the incidence of hypokalemia, hypochloraemia and hypercapnia, and avoid deterioration.

Abstract
PURPOSE To evaluate the effect of animated cartoons with children's songs to increase compliance with ultrasonography (US) examination in young children. MATERIALS AND METHODS Animated cartoons with children's songs viewed on a cell phone were played just before the start of US examination when pediatric patients were agitated or irritable. The effect of this method was evaluated for initial responses and sustained responses (grade 0, no response; 1, partial response; and 2, good response). Site of US examination, scan duration, and the helpfulness of this method (0, useless; 1, partially helpful; and 2, very helpful) were also recorded. RESULTS Among 464 pediatric patients who underwent US during the study period, 88 children (19%) needed to be calmed (67 abdominal and 21 other parts of the body). All subjects were less than five years of age (mean 1.5 years), except for four patients with mental retardation. Scan duration was less than 5 minutes in almost all examinations. Five children refused to watch the cartoon. Initial responses were good in 75 and partial in eight children. Sustained responses were good in 70 and partial in 12 children. The cartoons were very helpful in 73 (83%) and partially helpful in nine (10%) children. The effect of watching the cartoon did not change with sex, age (less or more than one year), or site of examination. CONCLUSION Animated cartoons with children's songs viewed on a cell phone were helpful (93%) in increasing compliance with US examination in young children of both the abdomen and other parts.

Abstract
Acute abdomen is a medical emergency, in which there is sudden and severe pain in abdomen of recent onset with accompanying signs and symptoms that focus on an abdominal involvement. It can represent a wide spectrum of conditions, ranging from a benign and self-limiting disease to a surgical emergency. Nevertheless, only one quarter of patients who have previously been classified with an acute abdomen actually receive surgical treatment, so the clinical dilemma is if the patients need surgical treatment or not and, furthermore, in which cases the surgical option needs to be urgently adopted. Due to this reason a thorough and logical approach to the diagnosis of abdominal pain is necessary. Some Authors assert that the location of pain is a useful starting point and will guide a further evaluation. However some causes are more frequent in the paediatric population (like appendicitis or adenomesenteritis) or are strictly related to the gender (i.e. gynaechologic causes). It is also important to consider special populations such as the elderly or oncologic patients, who may present with atypical symptoms of a disease. These considerations also reflect a different diagnostic approach. Today, surely the integrated imaging, and in particular the use of multidetector Computed Tomography (MDCT) has revolutionised the clinical approach to this condition, simplyfing the diagnosis but burdening the radiologists with the problems related to the clinical management. However although CT emerging as a modality of choice for evaluation of the acute abdomen, ultrasonography (US) remains the primary imaging technique in the majority of cases, especially in young and female patients, when the limitation of the radiation exposure should be mandatory, limiting the use of CT in cases of nondiagnostic US and in all cases where there is a discrepancy between the clinical symptoms and negative imaging at US.

Abstract
Acute abdomen can be defined as a medical emergency in which there is sudden and severe pain in abdomen with accompanying signs and symptoms that focus on an abdominal involvement. It accounts for about 8 % of all children attending the emergency department. The goal of emergency management is to identify and treat any life-threatening medical or surgical disease condition and relief from pain. In mild cases often the cause is gastritis or gastroenteritis, colic, constipation, pharyngo-tonsilitis, viral syndromes or acute febrile illnesses. The common surgical causes are malrotation and Volvulus (in early infancy), intussusception, acute appendicitis, and typhoid and ischemic enteritis with perforation. Lower lobe pneumonia, diabetic ketoacidosis and acute porphyria should be considered in patients with moderate-severe pain with little localizing findings in abdomen. The approach to management in ED should include, in order of priority, a rapid cardiopulmonary assessment to ensure hemodynamic stability, focused history and examination, surgical consult and radiologic examination to exclude life threatening surgical conditions, pain relief and specific diagnosis. In a sick patient the initial steps include rapid IV access and normal saline 20 ml/kg (in the presence of shock/hypovolemia), adequate analgesia, nothing per oral/IV fluids, Ryle's tube aspiration and surgical consultation. An ultrasound abdomen is the first investigation in almost all cases with moderate and severe pain with localizing abdominal findings. In patients with significant abdominal trauma or features of pancreatitis, a Contrast enhanced computerized tomography (CECT) abdomen will be a better initial modality. Continuous monitoring and repeated physical examinations should be done in all cases. Specific management varies according to the specific etiology.

Abstract
Based on their clinical impression, the authors hypothesized that children with obesity may more commonly present with perforated appendicitis. Therefore, the authors reviewed their experience from 2008 to 2010 to determine whether obesity affected the clinical presentation of appendicitis. Variables studied were height, weight, use of diagnostic imaging, and clinical findings of appendicitis at presentation. Outcomes assessed were length of stay and complication rate. The study identified 319 patients with appendicitis. Children with obesity were more likely (P = .026) to present with perforation (28/62, 45%) than nonobese patients (78/257, 30%). Neither length of stay nor complication rate was affected by the presence of obesity. The data suggest that children with obesity are more likely to present with perforated appendicitis. This finding suggests that the diagnosis of appendicitis may be more difficult in obese patients or their presentation may be delayed. Practitioners should have heightened awareness in children with obesity and symptoms of abdominal pain.

Abstract
Appendicitis, intussusception, and hypertrophic pyloric stenosis (HPS) are three of the most common reasons for emergent abdominal imaging in pediatric patients. Although the use of computed tomography has risen dramatically over the past 2 decades, children are particularly at risk for the adverse effects of ionizing radiation, and even low-dose radiation is associated with a small but significant increase in lifetime risk of fatal cancer. In most emergency departments, the use of magnetic resonance (MR) imaging as a primary modality for the evaluation of a child with abdominal pain remains impractical due to its high cost, its limited availability, and the frequent need for sedation. Ultrasonography (US) does not involve ionizing radiation and, unlike MR imaging, is relatively inexpensive, is widely available, and does not require sedation. Another major advantage of US in abdominal imaging is that it allows dynamic assessment of bowel peristalsis and compressibility. Delayed diagnosis of any of the aforementioned disease processes can lead to serious morbidity and, in some cases, death. The ability to diagnose or exclude disease with US should be part of a core radiology skill set for any practice that includes a pediatric population.

Abstract
Acute pain in the right iliac fossa is common in children. It can arise from a wide variety of gastrointestinal and genitourinary processes that make up the differential diagnosis with acute appendicitis. In this article, we describe the most representative findings of these processes on ultrasonography. We emphasize the characteristics that enable these processes to be differentiated from acute appendicitis.

Abstract
BACKGROUND Little is known about 'normal' local sonographic changes occurring in the postoperative period after an uneventful appendectomy. OBJECTIVE To analyse the local changes on US examination occurring after uneventful open (OA) or laparoscopic (LA) appendectomy in children with normal histology and with nonperforated acute appendicitis. MATERIALS AND METHODS US was prospectively performed in 82 children (54 boys and 28 girls) aged 1-16 years (mean 11.6+/-3.2 years), 3 days following LA (n=51, 62%) or OA (n=31, 38%) for nonperforated appendicitis. Multivariate analysis was performed using stepwise logistic regression, with the following starting variables: surgical technique, gender, pathological finding, appendix location, and histology. RESULTS Of the 82 patients, 35 (42.7%) had postoperative pathological US findings such as peritoneal fluid, oedematous mesenteric fat and thickening of the bowel wall. While the overall incidence of pathological US findings between OA and LA groups was not significantly different, multivariate logistic regression analysis showed that OA is associated with a reduction by a factor of 0.35 in the odds ratio of postoperative pathological US findings (P=0.007). CONCLUSION Pathological US findings are common in children after appendectomy, particularly after LA. Awareness of these pathological findings might prevent unnecessary postoperative treatment.

OBJECTIVE The purpose of our study was to determine the frequency of hyperechogenicity of renal parenchyma in children with acute abdominal illness and to evaluate the assumed transient feature of this hyperechogenicity. MATERIALS AND METHODS Between January 2005 and February 2006, 189 consecutive patients (112 boys and 77 girls; mean age, 10 years) presenting with acute abdominal pain were examined with sonography. Patients with a known history of renal disease and those with acute urinary tract infection were excluded from the study. Echogenicity of the renal cortex in comparison with adjacent liver was recorded. Renal cortex echogenicity was divided into three groups; group 1, renal cortex echogenicity less than liver parenchyma echogenicity; group 2, renal cortex echogenicity similar to that of liver parenchyma; and group 3, renal cortex echogenicity greater than that of liver parenchyma. Patients with hyperechogenicity were reexamined with sonography after 2 weeks or more. The final sonographic diagnosis and clinical outcome were noted. RESULTS Renal cortex echogenicity was equal to or greater than that of the liver parenchyma in 18% (n = 34) of 189 patients. Increased echogenicity of the renal cortex returned to normal in 2 or more weeks in all patients. Three patients had no follow-up. Clinical diagnoses were idiopathic acute abdominal pain (n = 74), appendicitis (n = 83), mesenteric lymphadenitis (n = 15), ileocecitis (n = 7), gastroenteritis (n = 7), Crohn's disease (n = 1), intussusception (n = 1), and pneumonia (n = 1). No concurrent renal disease was diagnosed. CONCLUSION Increased echogenicity of renal parenchyma in children with acute illness is a transient feature and does not necessarily indicate renal disease.

Abstract
OBJECTIVES To describe the polymorphism of intestinal ultrasound findings in children with gastrointestinal symptoms of Henoch Schönlein purpura (HSP) and to investigate the clinical relevance of these findings in terms of symptoms and length of hospitalization. PATIENTS AND METHODS Clinical and ultrasound data from 43 consecutive children with HSP (36 with and 7 without abdominal symptoms) were reviewed. Patients with abdominal symptoms of HSP were divided into 4 groups (0-III) representing at ultrasound normal appearance and differentiated, pseudodifferentiated, and dedifferentiated bowel wall thickening, respectively. The diagnostic value of ultrasound in diagnosing gastrointestinal involvement of HSP (grades I-III) was calculated using as the standard of reference the absence or presence of clinical symptoms. Average duration of symptoms and hospitalization in the 4 groups was compared. RESULTS The respective sensitivity, specificity, positive predictive value, and negative predictive value of ultrasound for the diagnosis of gastrointestinal involvement of HSP was 83.3%, 100%, 100%, and 53.8%. Groups 0 to III contained, respectively, 5/36 (13.9%), 6/36 (16.7%), 22/36 (61.1%), and 3/36 (8.3%) patients. The groups' average duration of symptoms, respectively, was 2.20 +/- 2.06, 5.67 +/- 1.88, 6.29 +/- .94, and 17.67 +/- 2.66 days, whereas the length of hospitalization, respectively, was 4.80 +/- 2.96, 9.17 +/- 2.70, 11.46 +/- 1.35, and 24.67 +/- 3.82 days. The duration of both symptoms and hospitalization was significantly higher in group III than in the other groups (P < 0.05). CONCLUSIONS In children with gastrointestinal involvement of HSP, dedifferentiated wall thickening as shown by ultrasound is associated with a poor clinical prognosis.

Abstract
BACKGROUND The role of laparoscopic surgery in treating intussusception has been controversial. This study reviews our institution's experience with the laparoscopic approach (LAP) compared to the open surgical approach (OPEN). METHODS Retrospective analysis of all patients undergoing surgery for intussusception at our center from January 2002 to February 2006. Statistical assessment included Student's t test and chi2 analysis. RESULTS A total of 41 patients required operation for intussusception (18 LAP, 23 OPEN). Mean age was 22 months for LAP and 11 months for OPEN (P = .17). In the LAP group, 28% (5/18) were converted to an open procedure. Operative times and complications were not significantly different. Pathologic lead points were found in 33% (6/18) LAP and 35% (8/23) OPEN patients (P = 1.0). Time to full feeds was significantly shorter (LAP vs OPEN: 3.4 +/- 2.7 vs 5.6 +/- 3.4 days, P = .02). Length of stay was shorter (LAP vs OPEN: 4.8 +/- 3.5 vs 9.1 +/- 7.5 days, P = .03). CONCLUSIONS Intussusception can be treated safely and effectively using a LAP with a significant decrease in time to full feeds and length of stay. The LAP should be considered as the initial approach for stable patients with intussusception requiring operative intervention.

Abstract
BACKGROUND Intussusception (IS) is the most common cause of acute bowel obstruction in infants and young children. Ultrasonography is being increasingly used as the primary investigation for the diagnosis of IS and to guide air or hydrostatic enema reduction. However the accuracy of ultrasonography outside tertiary care settings in developed countries has not been assessed, particularly in Asia where the incidence of IS based on sonographic diagnosis has been reported as the highest in the world. OBJECTIVE The aim of this study was to evaluate the accuracy of ultrasonography in the diagnosis of acute IS in infants less than 2 years of age in a paediatric hospital in Vietnam. MATERIALS AND METHODS A prospective study was conducted at the National Hospital for Paediatrics, Hanoi, Vietnam, over a 14-month period recruiting patients <2 years of age with IS. Abdominal ultrasonography was performed on each patient and the accuracy of the diagnosis was evaluated against the final diagnosis provided by air enema and/or surgery. RESULTS A total of 640 infants <2 years of age presented with clinical symptoms and signs of IS. The diagnosis was confirmed in 533 patients via air enema or surgery. Abdominal ultrasonography was 97.5% (466/478) sensitive and 99% (106/107) specific in the detection of IS. CONCLUSION Ultrasonography is an accurate, safe and valuable clinical tool in the diagnosis of IS. The use of ultrasonography as a primary investigation for patients with suspected IS prevents unnecessary radiological or surgical procedures being performed, and reduces radiation exposure while maintaining a high level of diagnostic accuracy. These results validate the use of ultrasonography for the diagnosis of IS in a developing country setting.

Abstract
Do advances in MR imaging and Computed Tomography have encroached upon the private territory of Ultrasound-Doppler imaging on paediatric practice? Do the enthusiasm promoted by the use of CT on non traumatic acute abdomen in adult has contaminated the indomitable village of paediatric radiologist? Undoubtfully, Ultrasound-Doppler stayed the first imaging modality to perform. However, the habits are less crystallised than a few years ago. The goal of this article is to describe the ultrasound findings and the potential indications for MRI or CT in the major non traumatic abdominal paediatric emergencies.
