• Irritable Infant

  This mass is palpable to an experienced examiner in up to 80% to 90% of cases, but may be difficult to appreciate in the face of a dilated stomach or irritable infant. [basicmedicalkey.com]

• Hunting

  It may be only for a day or a week, but the cessation of vomiting suggests that the disturbance is due to the food, that the appropriate food has not been found, and so the hunt continues. [chestofbooks.com]

• Gastric Lavage

  Gastric lavage is useful in two ways, first in removing all irritating remnants of food from the stomach, and secondly in showing the physician how to regulate successfully the food and feeding. [chestofbooks.com]

• Vomiting

  Two days later the baby was brought again to the family practitioner with a history that he has been vomiting almost every feed and the vomiting was projectile immediately following each feed. [medindia.net]

  After vomiting, the infant is hungry and wants to feed again. As vomiting continues, a progressive loss of fluid, hydrogen ion, and chloride leads to hypochloremic metabolic alkalosis. [clinicalgate.com]

  The history is usually as follows : An infant, healthy at birth, seems to progress satisfactorily for two, three, or five weeks, and then vomiting comes on. It does not matter what the food is, breast or artificial feeding, the vomiting persists. [chestofbooks.com]

  Clinical signs and symptoms appear early in life and include projectile vomiting and dehydration. Narrowing of the pyloric canal due to hypertrophy of the surrounding circular muscle. It is usually seen in infants or young children. [icd10data.com]

  Hypertrophic pyloric stenosis should be suspected in all infants in the first several months of life with projectile vomiting. [merckmanuals.com]

• Persistent Vomiting

  Due to the loss of hydrochloric acid in the gastric contents from persistent vomiting, patients are at risk of electrolyte imbalance, specifically the characteristic hypochloremic metabolic alkalosis. [radiopaedia.org]

  Persistent vomiting is most often a result of esophagitis or gastritis and is managed by stopping the feedings for several hours, and then restarting feedings at low volume. [basicmedicalkey.com]

  vomiting expectantly because it usually resolves within 1-2 days Avoid the temptation to repeat ultrasonography or upper GI barium study; these invariably demonstrate a deformed pylorus, and results are difficult to interpret See Treatment and Medication [emedicine.medscape.com]

  Operative complications include mucosal perforation, continued postoperative bleeding (very rare), and persistent vomiting due to incomplete pyloromyotomy (rare). [patient.info]

  Infants with persistent vomiting at the age of 3 5 weeks after birth should be considered IHPS, and go to hospital as soon as possible in order to reduce the incidence of hypokalemia, hypochloraemia and hypercapnia, and avoid deterioration. [journals.plos.org]

• Vomiting in Infancy

  Infantile or congenital hypertrophic pyloric stenosis is one of the most common surgical causes of vomiting in infancy. [sonoworld.com]

  Of course, clinically it is important to consider other causes of vomiting in infancy. A degree of pylorospasm is common in infancy and is responsible for some delay in gastric emptying. The pylorus, however, appears sonographically normal. [radiopaedia.org]

Prognosis The prognosis of pyloric stenosis is very good for those that are diagnosed early and treated with surgery. Life expectancy of infants diagnosed with pyloric stenosis is the same as that of the average individual. [encyclopedia.com]

Prognosis Prognosis is excellent unless diagnosis is delayed and prolonged severe dehydration occurs. Mortality is rare after pyloromyotomy. Peters B, Oomen MW, Bakx R, et al ; Advances in infantile hypertrophic pyloric stenosis. [patient.info]
