==Overview==
==Overview==
Abdominal pain in [[children]] is a common presenting [[symptom]] in [[pediatrics]] [[primary care]]. There's multiple [[causes]] of abdominal pain that require different types of investigations and treatment options.


==Historical Perspective==
==Historical Perspective==


*[Disease name] was first discovered by [scientist name], a [nationality + occupation], in [year] during/following [event].
*[[Celiac disease]] was first discovered by Dutch [[Pediatricians|pediatrician]]<nowiki/>s, in late 1940s<ref name="urlCELIAC DISEASE">{{cite web |url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6203336/ |title=CELIAC DISEASE |format= |work= |accessdate=}}</ref>.
*In [year], [gene] mutations were first identified in the pathogenesis of [disease name].
*In late 1980s, the first classification and [[diagnostic criteria]] for [[functional gastrointestinal disorders]] was developed by a group of international experts were recruited by Professor Aldo Torsoli from Italy to develop Working Teams for the International [[Gastroenterology]] meeting in Rome 1988 to the goal was to answer difficult questions using a consensus methodology through the Delphi approach about a group of [[Gastrointestinal disorders|gastrointestinal disorder]]<nowiki/>s that had little scientific-based evidence to understand [[etiology]] [[pathophysiology]] and treatment at the time<ref name="urlWhat Is New in Rome IV">{{cite web |url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5383110/ |title=What Is New in Rome IV |format= |work= |accessdate=}}</ref>.

**Acute Abdominal pain(less than 1 week).
**Chronic Abdominal pain(more than 1 week).


==Pathophysiology==
==Pathophysiology==


*The pathogenesis of [disease name] is characterized by [feature1], [feature2], and [feature3].
*The [[pathogenesis]] of abdominal pain is related to either insult to intra-abdominal structures or extra-abdominal structure. Also it can be due to injury to somatic structures that's overlay the [[abdominal wall]] <ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>.
*The [gene name] gene/Mutation in [gene name] has been associated with the development of [disease name], involving the [molecular pathway] pathway.
*On Summary the [[pathophysiology]] of abdominal pain maybe due to :
*On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
**Visceral Pain:
*On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
***Result when there's a damage to [[nerve]] within the [[abdomen]].<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>
***Due to the fact that visceral [[nerve fibers]] that responsible for [[pain]] sensation are non-myelinated, the visceral pain is Vague, dull, poorly localized and slow on onset.<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>
***Different types of stimuli including chemical, [[osmotic]] and even normal [[peristalsis]] can stimulate these fibers.<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>
***Visceral pain is always sensed when the threshold of intensity or duration is reached.<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>
***Mild stimuli may result in sensing non-painful or vaguely un-comfortable sensation, in contrast to powerful stimulation to visceral [[nerve fibers]] which causes pain.<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>
***Example for [[pain]] caused due to over-sensation of visceral [[nerve fibers]] is functional abdominal pain.<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>
**Somatic Pain:
***Due to insult to somatic structures([[parietal peritoneum]], [[fascia]], [[muscles]], and [[skin]] of the [[abdominal wall]]).<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>.
***Somatic [[nerve fibers]] are [[myelinated]] that can rapidly transmit well localized [[painful]] stimuli<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>.
***Visceral [[pain]] can progress to somatic [[pain]] when the insult from intra-abdominal structures progress to affect the somatic structures(for example [[parietal peritoneum]])as happens in [[acute appendicitis]] which start as visceral pain after that it progress to somatic pain.<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>.

***This occur due to stimulation of [[spinal cord]] somatic sensory cell bodies which activated by stimuli from  [[visceral afferent fibers]], which located on the same level on the [[spinal cord]]<ref name="urlAbdominal pain in children">{{cite web |url=https://www.slideshare.net/azadhaleem/abdominal-pain-in-children-55395998 |title=Abdominal pain in children |format= |work= |accessdate=}}</ref>.


==Causes==
==Causes==
Disease name] may be caused by [cause1], [cause2], or [cause3].
There is a wide range of [[causes]] for [[pediatric]] abdominal pain which maybe due to a [[disease]] in variety of systems. In general, differentiating between acute and chronic pain in children is not easy, Despite it's being benign conditions in most [[children]] presenting with [[abdominal pain]] but some serious conditions may be the cause of the [[abdominal pain]]. On the table below there's some systems and related [[diseases]] that can cause abdominal pain in children:<ref name="urlEvaluation of abdominal pain in children - Etiology | BMJ Best Practice US">{{cite web |url=https://bestpractice.bmj.com/topics/en-us/787/aetiology |title=Evaluation of abdominal pain in children - Etiology &#124; BMJ Best Practice US |format= |work= |accessdate=}}</ref>

Overview

Abdominal pain in children is a common presenting symptom in pediatrics primary care. There's multiple causes of abdominal pain that require different types of investigations and treatment options.

Historical Perspective

  • Celiac disease was first discovered by Dutch pediatricians, in late 1940s[1].
  • In late 1980s, the first classification and diagnostic criteria for functional gastrointestinal disorders was developed by a group of international experts were recruited by Professor Aldo Torsoli from Italy to develop Working Teams for the International Gastroenterology meeting in Rome 1988 to the goal was to answer difficult questions using a consensus methodology through the Delphi approach about a group of gastrointestinal disorders that had little scientific-based evidence to understand etiology pathophysiology and treatment at the time[2].
  • In May of 2016, after Rome III had been in effect for a decade, Rome IV was released[3]. It is a result of collective work by committees that included more than 100 leading functional GI experts[3].

Classification

  • Abdominal pain in children may be classified according to age into two groups:[4]
    • Abdominal pain in children below five years old.
    • Abdominal pain in children above five years old.
  • Other method for classification of abdominal pain can be according to the duration of the pain[5]:
    • Acute Abdominal pain(less than 1 week).
    • Chronic Abdominal pain(more than 1 week).

Pathophysiology

  • The pathogenesis of abdominal pain is related to either insult to intra-abdominal structures or extra-abdominal structure. Also it can be due to injury to somatic structures that's overlay the abdominal wall [6].
  • On Summary the pathophysiology of abdominal pain maybe due to :
    • Visceral Pain:
      • Result when there's a damage to nerve within the abdomen.[6]
      • Due to the fact that visceral nerve fibers that responsible for pain sensation are non-myelinated, the visceral pain is Vague, dull, poorly localized and slow on onset.[6]
      • Different types of stimuli including chemical, osmotic and even normal peristalsis can stimulate these fibers.[6]
      • Visceral pain is always sensed when the threshold of intensity or duration is reached.[6]
      • Mild stimuli may result in sensing non-painful or vaguely un-comfortable sensation, in contrast to powerful stimulation to visceral nerve fibers which causes pain.[6]
      • Example for pain caused due to over-sensation of visceral nerve fibers is functional abdominal pain.[6]
    • Somatic Pain:
    • Referred Pain:

Causes

There is a wide range of causes for pediatric abdominal pain which maybe due to a disease in variety of systems. In general, differentiating between acute and chronic pain in children is not easy, Despite it's being benign conditions in most children presenting with abdominal pain but some serious conditions may be the cause of the abdominal pain. On the table below there's some systems and related diseases that can cause abdominal pain in children:[7]

Causes of Abdominal pain In Children
System Disesease
Gastrointestinal Appendicitis[8], Gastrointestinal reflux disease[9], constipation [9],irritable bowel syndrome[10], celiac disease [11],Meckel's diverticulum[12], Intussusception[13], Volvulus[14].functional dyspepsia (FD)[15], abdominal migraine (AM)[15], functional abdominal pain (FAP) and functional abdominal pain syndrome (FAPS)[15]
Genitourinary Nephrolithiasis[16] , urinary tract infection[17].
Infections viral (mesenteric adenitis)[18], gastroenteritis[19],Multisystem Inflammatory Syndrome in Children (MIS-C) caused by covid-19[20]
Gynecologic Dysmenorrhea.[21]
Psychology Anxiety [22]
Others Toxins (lead poising)[23] , Sickle cell disease[24].

Differentiational Diagnosis of Abdominal Pain Children

For further information about the differential diagnosis, click abdominal pain differential diagnosis.

Epidemiology and Demographics

  • The pooled prevalence of abdominal pain in children is approximately 13.5% per 196,472 individuals worldwide.[15]
  • Abdominal pain is about 5% of presented cases in pediatrics, surgery is required only in 7% of cases, and non-specific diagnosis in up to 15%[25].
  • In 2001,the incidence of nonspecific abdominal pain was estimated to be 25% cases per 1,000 individuals in Netherland.[26]
  • Incidence of appendicitis is 11/10,000 population per year[27]
  • At least,20% of children present with abdominal pain,5% of them need hospitalization[28].

Age

Gender

  • Females are more commonly affected with abdominal pain than males.[31]
  • Appendicitis male to female ratio is (1.4:1) with life time risk of 8.6% in males and 6.7% in females[27]

Race

  • There is no racial predilection for abdominal pain in children

Risk Factors

Natural History, Complications and Prognosis

  • Abdominal pain is a common presenting symptom in pediatrics primary care. Most of times it's due to benign causes without risk for complications, but severe abdominal pain maybe an alarming sign for abdominal pathology that requires surgical intervention[34]
  • Early clinical features of acute appendicitis include pain that's start in the middle of the abdomen and radiate to the right iliac fossa, followed y fever and vomiting[35].
  • Prognosis of infantile colic is generally good,One self-reporting parent questionnaire on crying patterns found that 29% of infants aged 1 to 3 months cried for more than 3 hours a day, but the estimated prevalence of the age of 4 to 6 months found to be between 7% to 11%[36].

Diagnosis

Diagnostic Criteria

  • The diagnosis of appendicitis is made with Pediatrics Appendicitis score[37] :
Pediatrics Appendicitis score
Variable Score
Pain migrating to right lower quadrant 1
Anorexia 1
Nausea/vomiting 1
Fever>38 1
Right Iliac Fossa Pain 2
Pain with Cough/Percussion/Hopping 2
White Blood Cell Count>10,000 cells/ml 1
Neutrophils count>7,500 1
Total score 10
  • If the score is 5 or less: Appendicitis is less likely or excluded, If the score is more than 5: Appendicitis is high likely to be the diagnosis[38].
  • The diagnosis of Functional abdominal pain is established by using New Rome IV Criteria[39]:
    • All aspects of criteria must be reached for at least two month before the diagnosis, and the criteria must be fulfilled for at least four time per month[40].
    • New Rome IV Criteria include all of the following [40]:
      • Abdominal pain that may occur in episodic or continuous manner, pain that not occur only during physiological events like eating[40].
      • Not fulfill the criteria of any other functional GI disorders, like irritable bowel syndrome and abdominal migraine[40].
      • Abdominal pain that can not fully explained after full assessment[40].

Symptoms

  • First, Red flag symptoms must be excluded:
    • Weight loss[41].
    • Hemodynamic instability[41].
    • Bilious vomiting[41].
    • Bloody vomiting or stool[41].
    • Abdominal pain that wake up the child at night[41].
  • Symptoms associated with abdominal pain may vary according to the cause[42]:
Disease Associated Sympyoms
Colic Irritability, paroxysmal crying[43]
Appendicitis Vomiting,fever, localized right lower quadrant tenderness[44].
Irritable bowel syndrome Diarrhea, Constipation[45].
Hepatitis jaundice[46]
Henchon-schonlein purpura Skin Rash[47]
Urolithiasis Hematuria[48]
Pyelonephritis Dysuria, fever, urinary frequency, vomiting.[49]

Physical Examination

  • First, check vital signs, growth parameters and if there is evidence of failure to thrive. [41].
  • Inspect abdominal wall contour, protrusions, or skin abnormalities.[41]
  • Palpate superficially while looking to patient's face.[25]
  • Deep palpation for masses, kidney, spleen and liver[25].
  • Percussion and auscultation[41].
  • Digital rectal examinations and genital examinations[42]

Laboratory Findings

  • Initial laboratory tests according to symptoms include:
    • Complete blood count, Urine analysis, Stool analysis.[50]
    • Liver enzyme, pancreatic enzymes if liver and pancreas diseases in suspected[30].
    • Electrolyte (Sodium and serum bicarbonate levels) and creatinine, and glucose levels are useful in assessment of dehydration in patient with gastroenteritis[51]

Electrocardiogram

There are no ECG findings associated with abdominal pain in children.

X-ray

  • Plain abdominal pain X-ray may show evidence of bowel obstruction, free air and kidney stone[6].

Ultrasound

  • Ultrasound may be helpful in the diagnosis of appendicitis [30].
  • Findings on an ultrasound suggestive of appendicitis include:
    • aperistaltic, non-compressible, width(>6 mm outer diameter), when compressed it's appears round[52].

Treatment

Medical Therapy

  • The mainstay of therapy for acute gastroenteritis depends on the degree of dehydration ranging from simple oral rehydration at home to hospital admission[55].
  • In functional abdominal pain if bloating is predominate symptom, dietary measures may be effective for example, a low-FODMAP diet to exclude foods with certain types of carbohydrates including wheat, various fruits, lactose, fructose, and some artificial sweeteners[40]. If constipation is a predominate symptoms, incorporating non-stimulant laxatives such as PEG-3350 or increased fiber diets can be helpful[40]. Pharmacological treatment with drugs like selective serotonin reuptake inhibitors (SSRIs) or tricyclic antidepressants (TCAs) are often used to treat functional abdominal pain[40].

Surgery

  • Surgery is the mainstay of therapy for appendicitis, which can be done either laparoscopically or open[52] .

Prevention

  • Effective measures for the primary prevention of acute gastroenteritis include handwashing, breastfeeding, and rotavirus vaccination[51].
