What is the meaning of IHPS?
Practice Essentials. Pyloric stenosis, also known as infantile hypertrophic pyloric stenosis (IHPS), is the most common cause of intestinal obstruction in infancy. IHPS occurs secondary to hypertrophy and hyperplasia of the muscular layers of the pylorus, causing a functional gastric outlet obstruction.
What is the classic presentation of pyloric stenosis?
Signs include: Vomiting after feeding. The baby may vomit forcefully, ejecting breast milk or formula up to several feet away (projectile vomiting). Vomiting might be mild at first and gradually become more severe as the pylorus opening narrows.
What are the symptoms of pyloric stenosis in adults?
Common clinical symptoms of adult pyloric stenosis include:
- Projectile vomiting of nonbilious (no bile) partially digested food, soon after eating.
- History of frequent pain in the upper abdomen which is temporarily relieved after vomiting.
- Abdominal distension.
- Early satiety.
- Weight loss.
Can antibiotics cause pyloric stenosis?
Doctors have known that using the antibiotic erythromycin can increase the risk of pyloric stenosis in infants. The new findings confirmed that link, and also found that the antibiotic azithromycin (Zithromax) is associated with a higher risk of pyloric stenosis when given to infants under 6 weeks old.
Is IHPS genetic?
IHPS is probably inherited as a multifactorial trait, aggregating in families under the influence of multiple environmental and genetic factors.
What are the long term effects of pyloric stenosis?
There are no long-term effects. Recurrence of HPS is extremely rare with only a one percent chance. The rare baby with recurrent pyloric stenosis is still expected to have a normal gastro-intestinal tract long term, but may need additional surgery or nutritional therapy to recover.
What is the most common symptom in a child with pyloric stenosis?
The most common symptoms noted in a baby with pyloric stenosis is forceful, projectile vomiting. This kind of vomiting is different from a “wet burp” that a baby may have at the end of a feeding. Large amounts of breast milk or formula are vomited, and may go several feet across a room.
Is pyloric stenosis painful?
Symptoms and Causes Infants with pyloric stenosis may eat well but have these symptoms: Frequent projectile vomiting (forceful vomiting), usually within a half hour to an hour after eating. Abdominal (belly) pain.
Can pyloric stenosis go away on its own?
Pyloric stenosis needs to be treated. It won’t improve on its own. Your child will need surgery called pyloromyotomy. During this surgery, which can be done laparoscopically, a surgeon will cut through part of the thickened muscle in order to restore a pathway for food and liquid to pass through.
How can you tell the difference between GERD and pyloric stenosis?
Pyloric stenosis, is far less common than GERD. It occurs when, the valve at the bottom of the stomach grows so tight, that liquid in the stomach comes shooting back up. The classic thing with pyloric stenosis is projectile vomiting, where the vomit shoots out forcefully away from the body.
Can azithromycin cause pyloric stenosis?
Exposure to oral azithromycin in the newborn period increases the risk of developing pyloric stenosis. Although this risk is highest if the exposure occurred in the first 2 weeks of life, the risk extends out to 6 weeks of age.
What is the drug of choice for pyloric stenosis?
The intravenous dose of atropine for treatment of pyloric stenosis ranges in studies from 0.04 to 0.225mg/kg/day and is given for 1 – 10 days. Oral atropine (0.08 – 0.45mg/kg/day) is continued, after IV therapy has been deemed successful, for 3 weeks to 4 months.
