Abstract
Bowel obstruction (BO) in children has a wide differential diagnosis, ranging from non-urgent conditions to surgical emergencies. Abdominal radiographs are most often used as the first imaging modality for the evaluation of obstruction. However, for some indications, ultrasound can be the primary imaging modality. Therefore, it is incumbent on radiologists to recognize the types of bowel obstruction that can be recognized with US. Key sonographic features of BO include differential dilation of bowel loops, bowel wall thickening, and free fluid. "Do Not Miss" findings that indicate need for emergent treatment include volvulus, pneumoperitoneum, and/or signs of ischemia (bowel wall thinning and/or absent perfusion). The aim of this pictorial essay is to provide guidance on the sonographic technique and findings that enable identification of BO on US. Examples of neonatal BO on US, including common and less frequently encountered etiologies, are illustrated in this pictorial essay.

Elsayed Y, Soylu H. Point-of-care abdominal ultrasound in pediatric and neonatal intensive care units. Eur J Pediatr 2024; 183:2059-2069. [PMID: 38459132 DOI: 10.1007/s00431-024-05443-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 01/15/2024] [Accepted: 01/18/2024] [Indexed: 03/10/2024]
Abstract
A spectrum of critical abdominal pathological conditions that might occur in neonates and children warrants real-time point-of-care abdominal ultrasound (abdominal POCUS) assessment. Abdominal radiographs have limited value with low sensitivity and specificity in many cases and have no value in assessing abdominal organ perfusion and microcirculation (Rehan et al. in Clin Pediatr (Phila) 38(11):637-643, 1999). The advantages of abdominal POCUS include that it is non-invasive, easily available, can provide information in real-time, and can guide therapeutic intervention (such as paracentesis and urinary bladder catheterization), making it a crucial tool for use in pediatric and neonatal abdominal emergencies (Martínez Biarge et al. in J Perinat Med 32(2):190-194, 2004) and (Alexander et al. in Arch Dis Child Fetal Neonatal Ed 106(1):F96-103, 2021). Conclusion: Abdominal POCUS is a dynamic assessment with many ultrasound markers of gut injury by two dimensions (2-D) and color Doppler (CD) compared to the abdominal X-ray; the current evidence supports the superiority of abdominal POCUS over an abdominal X-ray in emergency situations. However, it should still be considered an adjunct rather than replacing abdominal X-rays due to its limitations and operator constraints (Alexander et al. in Arch Dis Child Fetal Neonatal Ed 106(1):F96-103, 2021). What is Known: • Ultrasound is an important modality for the assessment of abdominal pathologies. What is New: • The evidence supports the superiority of abdominal POCUS over an abdominal X-ray in emergency abdominal situations in the neonatal and pediatric intensive care units.

Abstract
OBJECTIVE To evaluate the sensitivity and specificity of clinical, laboratory, and radiological markers and the neonatologist-performed intestinal ultrasound (NP-IUS) for treatment interventions in preterm neonates who developed necrotizing enterocolitis (NEC). STUDY DESIGN This was a case-control study of preterm neonates < 35 weeks with a diagnostic workup for NEC. The diagnostic workup included NP-IUS performed by trained neonatologists using a standard protocol, abdominal roentgenogram (AXR), and laboratory investigations. Intestinal ultrasound (IUS) performed by two neonatologists was standardized to detect 11 injury markers. AXRs were read independently by experienced pediatric radiologists. The investigators who retrospectively interpreted the IUS were blinded to the clinical and treatment outcomes. RESULTS A total of 111 neonates were assessed. Fifty-four did not require intervention and formed the control group. Twenty cases were treated medically, 21 cases were treated with late surgery for stricture or adhesions, and 16 were treated with early surgery. The integrated model of cumulative severity of ultrasound markers, respiratory and hemodynamic instability, abdominal wall cellulitis, and C- reactive protein > 16 mg/L had an area under the curve (AUC) of 0.89 (95% confidence interval [CI]: 0.83-0.94%, p < 0.0001) for diagnosing NEC requiring surgical intervention. We also investigated the utility of Bell's classification to diagnose either the need for surgery or death, and it had an AUC of 0.74 (95% CI: 0.65-0.83%, p < 0.0001). CONCLUSION In this cohort, a combination of specific IUS markers and clinical signs of instability, abdominal wall cellulitis, plus laboratory markers were diagnostic of NEC requiring interventions. KEY POINTS · The diagnosis of necrotizing enterocolitis requires a combination of markers.. · The combination of specific ultrasound markers, clinical signs, and laboratory markers were diagnostic of NEC requiring intervention.. · The intestinal ultrasound performed by a trained neonatologist was the most sensitive diagnostic marker of NEC requiring surgical intervention..

Abstract
Bowel ultrasound (US) is a low-cost, non-invasive, bed side practice and a reproducible procedure that represents a high yield tool in clinical practice and in the diagnostic workup of a consistent group of acute and chronic gastrointestinal (GI) tract disease. Moreover, in case of GI diseases of neonatal and pediatric age, it allows an easier evaluation due to the small body size and scarce presence of fat tissue in the abdominal wall and peritoneal cavity and gas content. No particular preparation of the patient is needed, nevertheless a 3- to 5-hour fasting state improves the quality of the examination. The exam focuses on wall thickness and stratification, lumen content, distensibility and compressibility, presence of peristalsis of explorable segment of the GI tract and includes the investigation of mesentery, perivisceral tissues and nodes features. Color doppler flowmetry admits a qualitative evaluation of GI wall and mesentery vascularization. Healthy GI wall appears at a US evaluation as a multilayered structure in which hyperechoic and hypoechoic layers alternate sequentially. In this article we provide a quickly available overview on findings, signs and applications of US in major GI pediatric diseases.

Abstract
Purpose To compare and analyze the therapeutic effects of endoscopy-assisted laparoscopic surgery (EALS) and laparoscopic surgery (LS) in the treatment of gastric duplication cysts (GDCs). Patients and Methods We reviewed the clinical data of children with GDCs who underwent surgical treatment at Hubei Maternal and Child Health Hospital, Yijishan Hospital of Wannan Medical College, and Qingdao Women and Children's Medical Center from September 2014 to November 2022. Results The study comprised 29 children with GDCs, including 14 in the EALS group and 15 in the LS group. There was no significant difference between the two groups in terms of age, sex, weight, and cyst size characteristics. There was a significant difference between the two groups in terms of average surgical time (P>0.05), which was 1.100 ± 0.833 hours in the EALS group and 1.933 ± 0.159 hours in the LS group. There was a significant difference between the two groups (P<0.05) in average intraoperative blood loss, which was 7.93 ± 3.81 milliliters in the EALS group and 11.80 ± 2.72 milliliters in the LS group. There was a significant difference between the two groups (P<0.05) in average postoperative fasting time, which was 73.79 ± 8.36 hours in the EALS group and 114.1 ± 9.24 hours in the LS group. There was a significant difference between the two groups (P<0.05) in average postoperative hospital stay, which was 10.21 ± 4.25 days in the EALS group and 14.47 ± 4.36 days in the LS group. Conclusion EALS technology can not only shorten surgical time, accurately locate GDCs, reduce injuries, and decrease the probability of complications but also achieve treatment goals safely and reliably.

Abstract
Introduction Doppler ultrasound of the portal vein peak systolic velocity and hepatic artery peak systolic velocity and resistive index in children is often performed during abdominal ultrasound for the assessment of liver and other abdominal pathology. However, evidence-based reference values are not available. We aimed to determine these reference values and to investigate whether they are age-dependent. Methods Children who underwent abdominal ultrasound between 2020 and 2021 were retrospectively identified. Patients without hepatic or cardiac abnormalities at the time of ultrasound or during at least 3 months follow-up were eligible for the study. Ultrasound without hepatic hilum portal vein peak systolic velocity and/or hepatic artery peak systolic velocity and resistive index measurements were excluded. Age-dependent changes were analyzed using linear regression. Normal range reference values were described using percentiles for all ages, and for age subgroups. Results One-hundred ultrasound examinations performed in 100 healthy children aged 0-17.9 years (median 7.8 years, interquartile range 1.1-14.1 years) were included. Ninety-nine portal vein peak systolic velocity and 80 hepatic artery peak systolic velocity and resistive index measurements were obtained. There was no significant association between portal vein peak systolic velocity and age (β = -0.056, p = 0.68). There were significant associations between age and hepatic artery peak systolic velocity, and between age and hepatic artery resistive index (β = -0.873, p = 0.04 and β = -0.004, p < 0.001, respectively). Detailed reference values were provided for all ages, and for age subgroups. Conclusion Reference values for the hepatic hilum portal vein peak systolic velocity, hepatic artery peak systolic velocity, and hepatic artery resistive index in children were established. Portal vein peak systolic velocity is not age-dependent, whereas hepatic artery peak systolic velocity and hepatic artery resistive index decrease when children get older.

Abstract
Point-of-care ultrasonography (POCUS) refers to the use of portable imaging performed by the provider clinician at the bedside for diagnostic, therapeutic, and procedural purposes. POCUS could be considered an extension of the physical examination but not a substitute for diagnostic imaging. Use of POCUS in emergency situations can be lifesaving in the NICU if performed in a timely fashion for cardiac tamponade, pleural effusions, pneumothorax, etc, with potential for enhancing quality of care and improving outcomes.
In the past 2 decades, POCUS has gained significant acceptance in clinical medicine in many parts of the world and in many subspecialties. Formal accredited training and certification programs are available for neonatology trainees as well as for many other subspecialties in Canada, Australia, and New Zealand. Although no formal training program or certification is available to neonatologists in Europe, POCUS is widely available to providers in NICUs. A formal institutional POCUS fellowship is now available in Canada. In the United States, many clinicians have the skills to perform POCUS and have incorporated it in their daily clinical practice. However, appropriate equipment remains limited, and many barriers exist to POCUS program implementation.
Recently, the first international evidence-based POCUS guidelines for use in neonatology and pediatric critical care were published. Considering the potential benefits, a recent national survey of neonatologists confirmed that the majority of clinicians were inclined to adopt POCUS in their clinical practice if the barriers could be resolved.
This technical report describes many potential POCUS applications in the NICU for diagnostic and procedural purposes.

Diagnostic Accuracy of Acid-Base Status in Infants with Hypertrophic Pyloric Stenosis. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9121815. [PMID: 36553259 PMCID: PMC9776884 DOI: 10.3390/children9121815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/21/2022] [Accepted: 11/23/2022] [Indexed: 11/26/2022]
Abstract
Background: Hypertrophic pyloric stenosis is a condition in newborns in which the hypertrophic pyloric muscle causes gastric obstructive symptoms of progressive vomiting leading to hypochloremic hypokalemic metabolic alkalosis. The main aim of the research was to assess whether, based on the acid-base status, we can distinguish newborns who vomit due to pylorostenosis, compared with newborns who vomit for other unspecific reasons. Methods: The electronic records of patients in the hospital information system treated under the diagnosis Q40.0 (Congenital hypertrophic pyloric stenosis) (n = 69/included in the study = 53) in the period from 1 January 2014 to 1 January 2022 were reviewed retrospectively. For the purposes of the control group, the electronic records of patients treated in the emergency department with a diagnosis of R11.0 (Nausea and vomiting) (n = 53) without an established cause were randomly reviewed. In addition to the main aim, other research outcomes were to determine differences between groups in the following variables: duration of symptoms, family history, birth (preterm, term, post-term), birth weight, weight during examination, difference between birth weight and weight during an examination, type of vomiting, the thickness of the muscle wall and its length, and to calculate whether there is a correlation between the thickness and length of the pylorus muscle and the duration of vomiting in relation to variables from acid-base status. Results: In relation to the variables of interest between the groups, statistically significant differences were observed in the duration of symptoms (Mdn 4 vs. 2 days, p = 0.002), weight at examination (Mean 3880 vs. 4439 g, p = 0.001), difference in weight between birth and examination (Mean 374 vs. 1010 g, p < 0.0001), and type of vomiting (explosive 45 vs. 22, p = 0.023). In the acid-base status between the groups, a statistically significant difference was recorded for pH (Mdn 7.457 vs. 7.422, p < 0.0001), bicarbonate (Mdn 25 vs. 23 mmol/L, p = 0.000), total carbon dioxide (Mdn 25 vs. 24 mmol/L, p = 0.011), base excess (Mdn 0.8 vs. −1.3 mmol/L, p = 0.000), potassium (Mdn 5 vs. 5.3 mmol/L, p = 0.006), ionized calcium (Mdn 1.28 vs. 1.31 mmol/L, p = 0.011), and glucose (Mdn 4.5 vs. 4.9 mmol/L, p = 0.007). Regardless of the group, the correlations between the duration of vomiting (r = 0.316, p = 0.021 vs. r = 0.148, p = 0.290) and the thickness (r = 0.190, p = 0.172) and length (r = 0.142, p = 0.311) of the pylorus muscle in relation to pH did not exist or were weak. Conclusions: In a world where radiological methods are not equally available everywhere, with promising acid-base indicators, prospective multicenter studies and meta-analyses must be pursued in the future in order not to miss the possible much greater diagnostic potential of acid-base status.

Abstract
Chronic inflammatory bowel diseases (IBD) are chronic disorders of the gastrointestinal tract, with an increasing incidence in pediatric populations. Ultrasound of the intestinal wall represents the first-line imaging technique in children since it is a noninvasive method, is free of ionizing radiation, and is inexpensive. Furthermore, the absence of intestinal wall thickening has a good negative predictive value for IBD, which is greater for Crohn's disease than for ulcerative colitis. Ultrasound is used for the diagnosis of disease, for the differential diagnosis in IBD, in the follow-up of known IBD, in the definition of the site and extent of the disease, for the diagnosis of intestinal complications, for the evaluation of disease activity, in the definition of prognostic parameters, and in the post-operative follow-up.

Abstract
Applications for bowel US in children have been well described; however, less focus has been placed on patterns of bowel wall architectural change in specific disease states. This pictorial essay reviews normal bowel wall architecture and covers a variety of inflammatory, infectious, vascular and neoplastic disorders outside the neonatal period as seen on US, with illustrative pathological correlation. A thorough understanding of normal and abnormal bowel wall architecture can enrich sonographic interpretation and provide a valuable adjunct to appropriate clinical investigation.

Gastroprotective Effects of the Aqueous Extract from Taraxacum officinale in Rats Using Ultrasound, Histology, and Biochemical Analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2021:8987232.

Abstract
Taraxacum officinale F.H. Wigg. belonging to the family Asteraceae is an edible medicinal plant distributed worldwide. This study aimed to determine the gastroprotective effects of aqueous extract of T. officinale (AETo) in rats using ultrasound, histological, and biochemical analyses. In this study, gastric ulceration was induced by ethanol or piroxicam. Rats were then treated with AETo (3, 30, or 300 mg/kg). The area and histological appearance of gastric ulcers were quantified, and histochemical analysis was performed. The activity of AETo on inflammatory and oxidative stress markers was assessed in the ulcerated tissue. In addition, we investigated the thickness of the gastric wall using the ultrasound technique. Moreover, chemical analyses of AETo were performed. In rats with ethanol- or piroxicam-induced ulcers, AETo reduced the ulceration area, elevated mucin level, and the gastroprotective effect was confirmed by histological analysis. The gastroprotective effect was accompanied by increased activities of SOD, CAT, and GST, as well as an increase in GSH level and reduction in MPO activity. Furthermore, AETo reduced the thickness of the gastric wall in rats. Phytochemical analysis of AETo indicated phenolic acids and flavonoids as the main active compounds. In conclusion, the gastroprotective effect of AETo involves reduction in oxidative stress and inflammatory injury and increase in mucin content. This study advances in the elucidation of mechanisms of gastric protection of T. officinale, contributes to the prospection of new molecules gastroprotective, and proposes the ultrasonographic analyses as a new gastroprotective assessment tool in preclinical studies.

Abstract
Raoultella ornithinolytica is an opportunistic, aquaphilic and Gram-negative bacterium. Immune deficiency states and indwelling catheters provide a basis for most of the infections arising. R. ornithinolytica septicemia (ROS) is extremely rare in neonates but can be life threatening. Community-acquired ROS has not been described in neonates before. The diagnosis of neonatal septicemia is occasionally complicated by unusual clinical presentations. Pyloric stenosis is manifested by projectile, nonbilious vomiting and late findings, including weight loss, dehydration and electrolyte abnormalities beyond 4-6 weeks old. Community-acquired neonatal septicemia symptoms can sometimes be confused with symptoms of gastrointestinal obstructions in patients without risk factors for sepsis. Early diagnosis and appropriate antibiotics are essentials for a good prognosis in neonatal septicemia. Herein, we present a novel case of community-acquired ROS with an unusual presentation in a term infant and a review of the literature about ROS in the neonatal period.

Abstract
Hypertrophic pyloric stenosis is a common condition seen in the first 1 to 3 months after birth. Patients typically present with nonbilious projectile emesis after feeds that may result in hypokalemic, hypochloremic metabolic alkalosis. Although inability to tolerate feeds is frequently seen with self-limited conditions such as reflux, a low threshold to obtain an ultrasonographic image is important to prevent a delay in diagnosis. Although operative intervention is the treatment, it is imperative that patients are hydrated and serum electrolyte concentrations normalized before the induction of anesthesia. Laparoscopic pyloromyotomy is safe and effective. Postoperative emesis is normal, and reassurance to parents is appropriate. There is no significant long-term physiologic impairment from pyloric stenosis after successful surgical intervention.

Abstract
Enteric duplications (EDs) are rare congenital anomalies that result from defect during embryonic development of the gut. Although EDs can literally occur at any part of the gastrointestinal tract, ileocecal duplication is the commonest type followed by colorectal type. Morphologically, EDs are mostly cystic in nature; tubular duplications are uncommon. We report radiological diagnostic challenges encountered in dealing with a 10 month-old infant who presented with chronic constipation, progressive abdominal distension, and voiding difficulty for several weeks followed by colicky abdominal pain for three days. After a series of radiological procedures, a diagnosis of tubular colorectal duplication was made. The duplicated segment was loaded with impacted feces which exerted pressure effect on the rectum and urinary bladder. The case was treated surgically through laparoscopic procedure that included fenestration and stapling of the duplicated bowel followed by irrigation. Postoperatively, the child was followed up half-yearly for three years and was found to remain symptom-free. This case exemplifies the challenges a radiologist may experience while dealing with a case presenting with features of as acute-on-chronic intestinal obstruction and voiding difficulty.

Abstract
ABSTRACT To determine sensitivity and specificity of shear wave elastography in pediatric patients diagnosed with acute inflammation of the appendix. Forty-eight patients who were referred for abdominal pain, with 18 volunteers recruited for the evaluation. Alvarado scores were calculated on the patients. The elasticity and stiffness of the inflamed appendix tissues of patients and controls were measured using shear wave elastography. The anterior, posterior, and medial parts of the appendix tissue were measured, calculating the highest elasticity values in kPa. In the end, 32 patients with Alvarado scores between 7 and 9 (group 1) underwent surgery, whereas 3 of them had pathological specimens reporting as normal. Eight of the patients whose Alvarado scores were between 4 and 6 and had inflammatory conditions of the appendix (group 2), plus the control group totaled 16 patients (group 3). The median shear wave value was found to be significantly higher in group 1 (14.7 kPa) than in either group 2 (12.7 kPa) or group 3 (9.3 kPa) (P < 0.01). In the evaluation of the receiver operating characteristic curve, the cutoff value was discovered to be 14.3 kPA (95% CI: 0.753-0.995) in the acute appendicitis group, with a 100% sensitivity and 79.17% specificity. Shear wave elastography examination is not considered an invasive method and is an easily accessible diagnostic tool that can be used to differentiate between inflamed and noninflamed tissue in children. The quantitative measurement for flexibility of the appendix contributes to the diagnosis.

Abstract
PURPOSE The clinical treatment of ileocolic intussusception is different from that of small-bowel intussusception (SBI). This study aimed to analyze the differences between the two groups using ultrasonoscopy to avoid misdiagnosis. METHODS We conducted a retrospective study of intussusception in patients aged 0-18 years from September 2018 to March 2020. Clinical and ultrasonoscopy data were reviewed. RESULTS A total of 183 cases of intussusception were included in this study (123 cases of SBI and 60 of ileocolic intussusception). Ultrasonoscopy features that were significantly different between the two groups (p<0.05) included the lesion diameter, fat core thickness, outer wall thickness, lymph nodes inside intussusception, and lesion length. In the SBI group, 85% (104/123) of the normal ileocecal region was found in the right lower quadrant and 98% (120/123) of the normal ascending colon was found in the right side of the abdomen. In the ileocolic intussusception group, none of the normal ileocecal region was found and the ascending colon was found in only 5 cases (8%) (p<0.05). CONCLUSIONS The use of ultrasonography is the most practical method to distinguish SBI from ileocolic intussusception. In addition to comparing the differences between lesions, conventional probing of the ileocecal region and ascending colon will help to accurately differentiate between the types of intussusception and avoid misdiagnosis.

Abstract
Contrast-enhanced ultrasound (CEUS) has emerged as a valuable modality for bowel imaging in adults and children. CEUS enables visualization of the perfusion of the bowel wall and of the associated mesentery in healthy and disease states. In addition, CEUS images can be used to make quantitative measurements of contrast kinetics, allowing for objective assessment of bowel wall enhancement. Bowel CEUS is commonly applied to evaluate inflammatory bowel disease and to monitor treatment response. It has also been applied to evaluate necrotizing enterocolitis, intussusception, appendicitis and epiploic appendagitis, although experience with these applications is more limited. In this review article, we present the current experience using CEUS to evaluate the pediatric bowel with emphasis on inflammatory bowel disease, extrapolating the established experience from adult studies. We also discuss emerging applications of CEUS as an adjunct or problem-solving tool for evaluating bowel perfusion.

Abstract
Background and Aims: Ultrasound is a safe and non-invasive method for detecting numerous pathologies. Pediatric patients are often uncooperative which leads to decreased quality and increased time of scan. We compared the conventional means alone and combination of oral midazolam for the above cited purpose. Material and Methods: This double blind prospective study (CTRI/2016/06/007030) was conducted after obtaining due approval from institutional ethical committee. One hundred Children aged 2-6 years belonging to ASA class 1 or 2, posted for high resolution ultrasonography of abdomen were included in the study. They were randomised to receive midazolam 0.3 mg/kg mixed in 20 mL of apple juice (Group I) or 20 mL of apple juice alone (Group II) 20 minutes prior to the procedure. The parameters assessed were level of cooperation, sonologist's satisfaction, total scan time, heart rate and SpO2. Results: Out of 100 patients, 44 patients of group I and 42 of group II were analysed. The cooperation score was significantly higher in Group I (35%) than Group II (19%). Likert scale revealed very satisfied and satisfied rating in 61.3% (Group I) and 21.4% (Group II). The time taken by sonologist and number of attempts were significantly less in Group I than Group II. There was no difference in discharge time between the groups. There was no reportable adverse event in either group. Conclusion: Oral midazolam is a safe and effective agent to aid routine abdominal ultrasonography in pediatric patients.

Abstract
Contrast material-enhanced US is a technique that is approved by the U.S. Food and Drug Administration for the characterization of liver lesions and intravesicular applications in children; however, contrast-enhanced US has several other pediatric applications in clinical practice. The most common application is for patients with inflammatory bowel disease (IBD). Contrast-enhanced US can be used to diagnose IBD, distinguish regions of active or chronic inflammation of the bowel wall, and evaluate associated complications such as abscesses, fistulas, and strictures. Dynamic contrast material evaluation provides qualitative and quantitative information about mural and mesenteric blood flow, which is essential in the determination of disease activity in these patients. It also has the potential to provide a means of monitoring the response to therapy beyond endoscopy or MR enterography. In addition to its use for IBD, contrast-enhanced US can be used to assess for bowel perfusion when problem solving in patients with necrotizing enterocolitis, neonatal bowel infarction, or intussusception. It is a useful imaging technique to fortify diagnoses that may otherwise be indeterminate, such as appendicitis, epiploic appendagitis, intraluminal bowel masses, and complex cysts. Finally, innovative applications such as shear-wave elastography have the potential to provide information about the stiffness of the bowel wall. Online supplemental material is available for this article. ©RSNA, 2020 See discussion on this article by Watson and Humphries.

Abstract
Gastric gastrointestinal stromal tumor (GIST) is a mesenchymal neoplasm, typically arising from the muscularis propria layer of the stomach wall. Serosa-derived GIST is rarely seen and has not been reported yet. A 49-year-old Chinese female was presented with marked abdominal distension. Ultrasonography revealed a retroperitoneal tumor adjacent to the stomach wall with an intact structure of five echo layers, indicating a non-stomach tumor origin. Preoperative radiological studies suggested tight tumor-stomach adjacency, which was confirmed by intraoperative dissection. Initial frozen section indicated a pathological diagnosis of spindle cell tumor, which turned out to be a gastric GIST originated from the serosa layer of the stomach wall. The current case demonstrates the rare occurrence of serosa-derived GIST. This case also suggests difficulties in preoperative diagnosis of gastric GISTs, especially when uncommon pathological conditions like rare tumor origins were presented.

Abstract
The study of the gastrointestinal tract by imaging, particularly using ultrasound, is a required instrument for diagnosis of acute and chronic gastrointestinal pathologies in pediatric age. Actually, ultrasound plays an increasing role in the evaluation of gastrointestinal tract in neonatal and pediatric patients because of their small body habitus and the presence of less fat tissue in the abdominal wall and peritoneal cavity. Ultrasound has certain advantages, thanks to the new wide-spectrum frequency probes able to assess a detailed study of the morphological aspects and functional characteristics of bowel loops, adding a new dimension to the imaging of this body system. In this paper, we review anatomy, ultrasound technique and sonographic findings of bowel pathology frequently encountered in neonatal and pediatric emergency setting.

Abstract
PURPOSE Pediatric surgeon performed bedside ultrasound (PSPBUS) is a targeted examination that is diagnostic or therapeutic. The aim of this paper is to review literature involving PSPBUS. METHODS PSPBUS practices reviewed in this paper include central venous catheter placement, physiologic assessment (volume status and echocardiography), hypertrophic pyloric stenosis diagnosis, appendicitis diagnosis, the Focused Assessment with Sonography for Trauma (FAST), thoracic evaluation, and soft tissue infection evaluation. RESULTS There are no standards for the practice of PSPBUS. CONCLUSIONS As the role of the pediatric surgeon continues to evolve, PSPBUS will influence practice patterns, disease diagnosis, and patient management. TYPE OF STUDY Review Article. LEVEL OF EVIDENCE Level III.

Abstract
Despite hypertrophic pyloric stenosis (HPS) being one of the most frequently treated pediatric surgical conditions, its etiology remains incompletely understood. We review the diagnosis and treatment of this condition with an emphasis on the evolution of surgical techniques that led to laparoscopic pyloromyotomy, the most frequently performed technique for HPS today. In addition, we review key developments in the understanding of HPS etiology and treatment, including the postulated etiology of work-induced hypertrophy of the pylorus, its association with prokinetic macrolide antibiotics, and the emerging role of atropine sulfate as a medical treatment for HPS or a rescue treatment for incomplete myotomy.
