Vomiting

Regurgitation

Gastroesophageal reflux

Forceful expulsion of gastrointestinal contents through the mouth

28/04/23 3

Vomiting

◦the involuntary passage of gastric contents into the esophagus

◦reflux dribles effortlessly into or out of the

mouth

Most common in children (> infant)◦Confusing the parents◦Life-threatening causes of vomiting

Three distinct phases (1) nausea, (2) retching, (3) emesis

Not preceded in raised intracranial pressure or mechanical obstruction

EtiologyEtiology

• Neonates– Atresia esophagus, pylorus stenosis, spitting up– GER, NEC, chalasia, Infection (UTI, OMA, sepsis)

• Infants– pylorus stenosis, intususeption, hernia– RGE, gastroenteritis, infection, drugs, aerophagia

• Children– Intusuception, stricture, gastritis, apendisitis

Infection, drugs

RegurgitationRegurgitation20% general infant population

◦40% of children consulting a pediatrician◦70% of all 4 months old infants

regurgitate at least 1 x/day 25% is considered by the parents as ‘a problem’

RGE◦8% abnormal pH esophagus monitoring◦1/300 – 1/1000 ‘severe’ GER

The involuntary passage of gastric contents into the esophagus◦saliva, ingested food, drinks,

gastric/pancreatic/ biliary secretions◦normal phenomenon, +/- accompanying

symptoms◦physiologic or pathologic reflux (Carre 1983; Vandenplas, 1992; Orenstein, 1994; Vandenplas,

1993)

28/04/23 21

GER

GERGERPhysiologic reflux

◦occurs mainly after meal◦does not normally cause symptoms◦short duration of reflux episodes

Pathologic reflux◦frequent reflux episodes of longer duration◦reflux episodes occuring during the day/night◦may produce symptoms & inflamation/mucosal

injury

28/04/23 22

Mechanisms of GERMechanisms of GER

28/04/23 23

attenuated swallows, dysfunctional peristalsis

Length of LES, Maturation of LESTLES relaxation

Inadequate gravitation

delayed gastric emptying, distension

Deficient or delayed esophageal

acid clearance

Incompetent

Trigger factors favoring GERTrigger factors favoring GER

Increased abdominal pressure (overweight, constipation)

Increased respiratory effort related to exercise

(food) allergy, crying, cigarette smoking Hereditary predisposed

28/04/23 25

Clinical manifestation GERClinical manifestation GER

Emesis & regurgitation are the most common◦‘primary’ GER disease◦‘secondary’ GER disease

infection, metabolic disorders, & food allergy stimulation vomiting center in the dorsolateral

reticular formation by efferent & afferent impuls

Symptoms of GER (- disease)Symptoms of GER (- disease)

Usual manifestations◦Specific manifestation

regurgitation, nausea, vomiting◦Possibly related to complications

~ anaemia (iron defiency anaemia) haematemesis & melena dysphagia, weight loss, irritable infants ect ~ adult

28/04/23 27

Symptoms of GER (- disease)Symptoms of GER (- disease)Unusual presentations

◦~ chronic respiratory disease◦apnea, apparent life threatening, SIDS

~ to congenital and/or CNS abnormalities◦cerebral palsy, psychomotory retardation

A careful history, observation of feeding, & physical examination are mandatory

Treatment recommendationsTreatment recommendations1. a. Parental reassurance b. Milk-thickening agents (?)2. Prokinetics3. Positional adjuvant therapy4. a. H2 receptor antagonist b. Proton pump inhibitors5. Surgery

28/04/23 31

Regurgitation and feedingRegurgitation and feedingFrequent small feeding

◦Decrease the number of transient LES relaxations◦Reduced volume cause of distress to infants◦Restriction volume in clearly overfed babies

Thickening infants formula◦Decrease the frequency & volume of regurgitation◦time crying, improves sleep, caloric retention ,◦coughing (after feeding) (Vandenplas, 1994, Borelli,

1997)

28/04/23 32

Formula and milk-thickeningFormula and milk-thickeningThickening formula should be considered

as the first stepCan not be given to breastfed infantsGastric emptying : Casein >

Wheyhydrolysate

28/04/23 33

Gastrokinetic action indirect release of acetylcholine

in the myentericus plexusReduces regurgitation

◦The LES pressure and motility◦Esophageal peristalsis, gastric emptying

Increased salivary secretion◦protect esophagus via salivary component

(bicarbonat buffer)

28/04/23 34

Prokinetics

Position, crying, and refluxPosition, crying, and reflux

Sleeping and crying decrease GER◦Crying increases abdominal pressure, but also

increases LES-P

300 prone anti-trendelenburg position◦SIDS ?◦Beyond the age of SIDS ( > 12 months)

(Orenstein, 1990; Orenstein, 1997; Tobin, 1997)

GER - ASTHMAGER - ASTHMA

28/04/23 37

Vagal stimulation leading to bronchospasm

Laryngeal irritation by refluxate

Pulmonary aspiration of refluxate

Recent studies report that 45-75% of children with uncontrolled asthma suffer GOR

Prokinetic ◦ GER ~ cough episodes at night in 50% children ◦remission of resp. symptoms or less anti-asthma

medication

(McVeagh, 1987; Orenstein, 1988; Tucci F, 93; Pransky SM, 1992)
