6 Algorithmic approach to the children with acute abdominal pain requiring urgent management Joon Sung KimPediatr Gastroenterol Hepatol Nutr 2013; 16(4):

7 305 children aged 4 17 years consulting for abdominal pain 89.2% of children were diagnosed with general practice as functional abdominal pain (GPFAP). Headaches and bloating were positively associated with GPFAP whereas fever and 3 red flag symptoms were inversely associated. Additional diagnostic tests were performed in 26.8% of children. Spee LA et al. Scand J Prim Health Care Dec;31(4):

8 DOLORE ADDOMINALE RICORRENTE Nel 75% dei bambini in età scolare almeno un episodio di dolore addominale negli anni precedenti Nel 10-25% il dolore è ricorrente Età di insorgenza: 4-15 anni, con un picco intorno ai 10 anni Cause organiche in solo il circa 10% di essi

9 Prevalence of Functional Abdominal Pain in Children Norway 6% Sweden 13% Finland 8% USA 13% United Kingdom 12% Italy 10% Germany 2.5% Chitkara DK et al. Am J Gastroenterol 2005; 100:1868

10 DOLORE ADDOMINALE RICORRENTE Disordini Funzionali Gastrointestinali Dispepsia Funzionale Sindrome del Colon Irritabile Emicrania Addominale Dolore addominale funzionale aspecifico Gastroenterology 2006; 130:

18 DOLORE ADDOMINALE RICORRENTE La diagnosi di dolore addominale funzionale deve essere effettuata in positivo Test negativi non rassicurano il paziente, ma piuttosto rinforzano il modello medico di malattia Minime indagini diagnostiche

19 DOLORE ADDOMINALE RICORRENTE Anamnesi/Storia Psicosociale Esame obiettivo Indagini limitate

20 DOLORE ADDOMINALE RICORRENTE Anamnesi/Storia Psicosociale

21 Sintomi di allarme Dolore persistente al quadrante superiore destro o inferiore destro Artrite Dolore notturno Malattia perianale Disfagia Vomito persistente Perdita di peso involontaria Decelerazione della crescita lineare Pubertà ritardata Sanguinamento gastrointestinale Diarrea notturna Febbre inspiegabile Storia familiare di MICI, malattia celiaca o Malattia Ulceroso-Peptica

22 SINDROME DEL COLON IRRITABILE (SCI) Disordini che possono mimare la SCI: Malattie Infiammatorie croniche intestinali Malattia Celiaca Malassorbimento di Carboidrati Infezioni (es. giardia) Malformazioni Intestinali Neoplasie Alterazioni del tratto Genito-urinario Malattie Intestinali Allergiche

23 MALATTIE ASSOCIATE ALLA DISPEPSIA IN ETA PEDIATRICA Reflusso Gastroesofageo Esofagite Eosinofila Gastrite Eosinofilica Ulcera Gastrica o Duodenale Duodenite Malattie della colecisti Malattia Epatica Malattia Pancreatica

24 Objective To compare history and symptoms at initial presentation of patients with chronic abdominal pain (CAP) and Crohn s disease (CD). Study design:patients with abdominal pain for at least 1 month and no evidence of organic disease were compared with patients diagnosed with CD. Results Patients with functional gastrointestinal disorders had more stressors (P<0.001), were more likely to have a positive family history of irritable bowel syndrome, reflux, vomiting or constipation (P <.05); Anemia, hematochezia, and weight loss were most predictive of CD (cumulative sensitivity of 94%). J Pediatr 2013;162:783-7

25 POST-INFECTIOUS FUNCTIONAL GASTROINTESTINAL DISORDERS IN CHILDREN 36% of exposed children 87% Irritable Bowel Syndrome 24% Functional Dyspepsia Abdominal Pain 56% reported onset of pain following Acute Gastroenteritis (AGE) LOOK FOR PRAEVIOUS AGE Saps M, Staiano A et al. J Pediatr. 2008

26 IBS IN CHILDREN: PSYCHOSOCIAL HISTORY Evidence for stressful psychological stimuli Marital-Financial problems Death or illnesses Family history for IBS, IBD, PUD, Migraine Reinforcement of pain behavior by environmental factors Attention at time of pain Absence from school on days of pain

27 FAMILIAL AGGREGATION IN CHILDREN AFFECTED BY FUNCTIONAL GASTROINTESTINAL DISORDERS Prevalence of FGIDs in the group of parents of children with FGIDs: 64% the group of parents of children without FGIDs: 30.7% Association between the children s type of GI disorder and their parents disorder in 35/103 (33.9%) Anxiety was significally higher in the group of children with FGIDs (27.0%, vs 3, 8.3%) Buonavolontà R. JPGN 2010; 50(5):

28 FAMILIAL AGGREGATION IN CHILDREN AFFECTED BY FUNCTIONAL GASTROINTESTINAL DISORDERS Having a mother with FGID was a stronger predictor (OR=3.5%) of FGID than having a father with FGIDs Buonavolontà R. JPGN 2010; 50(5):

29 DOLORE ADDOMINALE RICORRENTE: ESAME OBIETTIVO Abdominal pressure tenderness Chronic constipation???

30 Occult constipation defined as abdominal pain disappearing with laxative treatment and not reappearing within a 6 month follow up Period was found in 92 patients (46 %) affectedd by RAP. Of these, 18 had considerable relief of pain when treated for a somatic cause but experienced complete relief only after laxative measures; Eur J Pediatr Jan 3. [Epub ahead of print]

31 Sixty-six % (28/42) children with functional dyspepsia were affected by functional constipation associated with delayed gastric emptying Normalization of bowel habit improved gastric emptying as well as dyspeptic symptoms Boccia et al. Clinical Gastroenterol Hepatol 2008

32 Constipation-IBS is the prevalent subtype in children, with a higher frequency in girls. In boys, diarrhea-ibs is the most common subtype. It is important to acquire knowledge about IBS subtypes to design clinical trials that may eventually shed new light on suptype-specific approaches to this condition. Giannetti E. J Pediatr (5): e1

33 DOLORE ADDOMINALE RICORRENTE: INDAGINI DI LABORATORIO Emocromo completo con formula Proteina C-reattiva Velocità di eritrosedimentazione Pannello metabolico completo Analisi urine Coprocoltura ed esame parassitologico delle feci Breath test idrogeno o trial con dieta priva di lattosio Anticorpi antitransglutaminasi Calprotectina fecale

34 FECAL CALPROTECTIN Patients affected by IBD had high levels of fecal calprotectin compared with healthy children (p < ) and children presenting with recurrent abdominal pain (p < ) Acta Paediatr. 2002;91(1): Sensibility and Specificity Intestinal ESR for the screening of IBD Eur J Gastroenterol Hepatol 2002;14 (8):841-5 Conclusions: Fecal calprotectin could be useful in differentiating the functional recurrent abdominal pain from the organic recurrent abdominal pain Canani RB, Miele E, Staiano A et al. Dig Liver Dis 2008; 40 (7):

35 J Pediatr Gastroenterol Nutr 2005; 40 (3): There is no evidence: On the predictive value of blood tests with or without alarm signs To suggest that the use of US examination of the abdomen and pelvis in the absence of alarm symptoms has a significant yields of organic disease

36 Value Of Abdominal Sonography In The Assessment Of Children With Abdominal Pain (AP) In children with AP without alarm symptoms: abnormalities in less than 1% In children with AP with alarm symptoms: abnormalities in 11% J Clin Ultrasound 2004; 26:

37 J Pediatr Gastroenterol Nutr 2005; 40 (3): There is little evidence that the use of endoscopy with biopsy or esophageal ph monitoring has a significant yield of organic disease in the absence of alarm symptoms

38 Based on the symptoms, endoscopic procedures were considered inappropriate if the Rome criteria had been met and appropriate if they had not been met. Of the 1624 procedures, 26% were considered inappropriate. Inappropriate procedures decreased significantly after publication of the Rome II criteria. Miele E et al. Aliment Pharmacol Ther 2010; 32:

39 ASSOCIATION BETWEEN HELICOBACTER PYLORI AND GASTROINTESTINAL SYMPTOMS IN CHILDREN Meta-analysis including 14 cross-sectional studies No association was found between RAP and H pylori infection and conflicting evidence for an association between epigastric pain and H pylori infection Evidence for an association between unspecified abdominal pain was found, but this finding could not be confirmed in children seen in primary care Spee LA et al. Pediatrics 2010;125(3):e651-69

40 Diagnostic test Basic laboratory tests Complete blood cell count Erythrocyte sedimentation rate or C-reactive protein Albumin and total protein Tissue transglutaminase IgA, total IgA Urinalysis and urine culture Stool guaiac, Calprotectin Diagnosis/findings Anemia, thrombocytosis, leukocytosis Systemic inflammation (e.g., inflammatory bowel disease) Nutrition and inflammation Celiac disease Hematuria, urinary tract infection Inflammation Additional laboratory tests/imaging/other testing to consider Basic metabolic panel, including blood urea nitrogen/creatinine Aspartate aminotransferase/alanine aminotransferase, γ-glutamyl transpeptidase Amylase, lipase Stool culture and staining for ova and parasites Breath testing for carbohydrate malabsorption Other symptom-guided diagnostic testing: abdominal ultrasound; contrast and other imaging studies; endoscopy/colonoscopy Approach to diagnostic testing Electrolyte disturbance, renal insufficiency Hepatobiliary inflammation or obstruction Pancreatitis Infectious colitis, giardiasis Lactose or fructose intolerance To be performed only if indicated by history, physicial examination findings or screening laboratory tests Eric Chiou and Samuel Nurko.
