“…It is allowed to diagnose children appendicitis by CT scan in our country and Simanovsky N et al had reported non-diagnostic or equivocal US in the evaluation of acute abdominal pain in children younger than 10 years old is probably sufficient to justify the additional CT radiation burden [ 38 ]. CT scanning had been done in most young children because the ultrasonic diagnosis was uncertain, little experience existed with the nonoperative treatment of APA, and the effect of an appendicolith on clinical outcomes was unclear.…”

BackgroundIn children less than 3 years of age, there is little experience in the nonoperative management of appendiceal phlegmon or abscess (APA), especially in APA with an appendicolith. The purposes of this study were to evaluate the effects of an appendicolith and the success rate of nonoperative management for APA in these young children.MethodsChildren younger than 3 years of age with APA who underwent attempted initial nonoperative treatment between January 2008 and December 2016 were reviewed. Based on the presence or absence of an appendicolith on admission ultrasonography examination or computed tomography scan, children were divided into two groups: appendicolith group and no appendicolith group.ResultsThere were 50 children who met the study criteria. Among 50 children, three children failed to respond to nonoperative treatment because of aggravated intestinal obstruction or recurrent appendicitis within 30 days of admission. The overall success rate for nonoperative management of APA was 94% (47/50) in children younger than 3 years old. The rate of diarrhea and CRP levels were higher in the appendicolith group than that of the no appendicolith group (P < 0.05). However, the success rate and the hospital length of stay for nonoperative treatment in the appendicolith group and the no appendicolith group were similar without statistical significance.ConclusionAPA with or without an appendicolith can have nonoperative management without immediate appendectomy in children less than 3 years old.

“…82,83 Ultrasound was found to be sufficient to confirm or rule out a surgical condition in approximately 97% of cases. 84 Using ultrasound as the primary imaging modality in children with suspected acute appendicitis has been shown to be cost-effective and to reduce the number of CT scans ordered 82,85,86 without resulting in inferior outcomes. 87,88 However, in some situations a definitive diagnosis cannot be made by ultrasound, requiring further evaluation with CT or MRI.…”

The aim of this review is to survey CT and MRI overuse in the paediatric emergency department (ED) population. CT is one of the most important modalities employed in the ED. Not surprisingly, its high accuracy, rapid acquisition and availability have resulted in overuse. An obvious limitation of CT is ionizing radiation; in addition there are economic implications to overuse. Studies from the last two decades have shown increase in paediatric ED CT utilization in the first decade, reaching a plateau forming around 2008, followed by a decrease in the last decade. This decrease occurred in conjunction with campaigns raising awareness to the risks of radiation exposure. Although a trend of decrease in overuse have been observed, great variability has been shown across different facilities, as well as among physicians, with more pronounced overuse in non-teaching and non-children dedicated EDs. The leading types of paediatric ED CTs are head and abdominal scans. Decision rules, such as PECARN for head injury and the Alvarado score for abdominal pain, as well as using alternative imaging modalities, have been shown to reduce CT overuse in these two categories. MRI has the obvious benefit of avoiding radiation exposure, but the disadvantages of higher costs, less availability and less tolerability in younger children. Although anecdotally paediatric ED MRI usage has increased in recent years, only scarce reports have been published. In our opinion, there is need to conduct up-to-date studies covering paediatric CT and MRI overuse trends, usage variability and adherence to clinical protocols.

“…It must, however, be acknowledged that ultrasound also has many benefits as a diagnostic tool. For example, according to a recent study, ultrasound alone can exclude or confirm 97% of abdominal surgical conditions in children under 10 years . Another study found ultrasound to be diagnostic in 48% of paediatric patients with acute abdominal pain .…”

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.
