DIOS was previously known as meconium ileus equivalent, a name which highlights its similarity to the intestinal obstruction seen in newborn infants with cystic fibrosis. [2] DIOS tends to occur in older individuals with pancreatic insufficiency .
Radiographs in meconium ileus classically demonstrate a bubbly appearance in the right lower quadrant due to a combination of ingested air and meconium. If, on contrast enema, reflux into the dilated distal small bowel loops can be achieved, the study is both diagnostic and therapeutic, as the ionic contrast medium can dissolve the meconium to ...
The presence of meconium ileus is not related to the severity of the cystic fibrosis. [4] The obstruction can be relieved in a number of ways. [5] Meconium ileus should be distinguished from meconium plug syndrome, in which a tenacious mass of mucus prevents the meconium from passing and there is no risk of intestinal perforation. Meconium ...
Meconium peritonitis; X-ray of a newborn with meconium pseudocyst resulting from bowel perforation. In this case the cause was atresia of the terminal ileum.There is a fine rim of calcification surrounding the big pseudocyst which shifts the other intestinal structures outwards.
The small bowel feces sign results from stagnation of enteric contents within dilated segments of the small intestine. [1] When intestinal motility is impaired due to obstruction, progressive dehydration of luminal contents occurs, leading to the formation of solid particulate matter that mimics feces. [3]
When physical examination of the newborn shows signs of a vertically transmitted infection, the examiner may test blood, urine, and spinal fluid for evidence of the infections listed above. Diagnosis can be confirmed by culture of one of the specific pathogens or by increased levels of IgM against the pathogen. [citation needed]
Meconium aspiration syndrome (MAS), also known as neonatal aspiration of meconium, is a medical condition affecting newborn infants. It describes the spectrum of disorders and pathophysiology of newborns born in meconium-stained amniotic fluid (MSAF) and have meconium within their lungs. Therefore, MAS has a wide range of severity depending on ...
Complication of ileal atresia, meconium peritonitis, in which the bowel perforated before birth. X-ray shows meconium pseudocyst. Prognosis is usually good if treated with surgery in infancy. The main factor in mortality is the availability of care and appropriate parenteral nutrition after surgery until the bowel can resume normal function. [1]
