What does pylorospasm mean?
Medical Definition of pylorospasm : spasm of the pyloric sphincter often marked by pain and vomiting.
What is a pylorus in medical terms?
(py-LOR-us) The part of the stomach that connects to the duodenum (first part of the small intestine). The pylorus is a valve that opens and closes during digestion. This allows partly digested food and other stomach contents to pass from the stomach to the small intestine.
What causes pyloric stenosis in infants?
Pyloric stenosis is considered a multifactorial trait. Multifactorial inheritance means that many factors are involved in causing a birth defect. The factors are usually both genetic and environmental. Often one gender (either males or females) is affected more frequently than the other in multifactorial traits.
Is pyloric stenosis genetic?
Other than male sex,2,3,9-11 the most consistently reported risk factors for pyloric stenosis are a family history of pyloric stenosis2-4,8,10,12-21 and being a firstborn child. The epidemiological features of skewed sex distribution and clustering of cases within families suggest a genetic component to the etiology.
What causes pylorospasm?
For many years radiologists considered pylorospasm to be due to spasm of the pyloric ring, where the ring was equated with the pyloric sphincter. It was thought that spasm of the ring (or “sphincter”) closed the pyloric aperture, thereby delaying gastric emptying and causing retention.
Where is the pylorus in the stomach?
If you were to take a look at your stomach, you would find a small section at the lower end called the pylorus. This is the place where the stomach connects to the duodenum, which is the first section of the small intestine. Between the pylorus and the duodenum, you can find the pyloric sphincter.
Which side of the body is the pylorus?
The pylorus is considered as having two parts, the pyloric antrum (opening to the body of the stomach) and the pyloric canal (opening to the duodenum). The pyloric canal ends as the pyloric orifice, which marks the junction between the stomach and the duodenum….
What are the symptoms of pyloric stenosis in babies?
- Vomiting after feeding. The baby may vomit forcefully, ejecting breast milk or formula up to several feet away (projectile vomiting).
- Persistent hunger. Babies who have pyloric stenosis often want to eat soon after vomiting.
- Stomach contractions.
- Changes in bowel movements.
- Weight problems.
How pyloric stenosis is diagnosed?
Abdominal ultrasound — the gold standard for diagnosing pyloric stenosis. This is an imaging technique that uses high frequency sound waves and a computer to create images of blood vessels, tissues, and organs. It is used to find out the thickness and length of the pyloric muscle.
Can pyloric stenosis be fatal?
Death from infantile hypertrophic pyloric stenosis is rare and unexpected. The reported mortality rate is very low and usually results from delays in diagnosis with eventual dehydration and shock.
How is Pylorospasm treated?
Antispasmodics have been proposed as a treatment for pylorospasm, but their use in neonates and infants has rarely been reported. Herein, we present a case of pylorospasm diagnosed in the neonatal period and successfully treated with intravenous atropine.
