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 .
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 ileus has a significant risk of intestinal perforation. In a barium enema, meconium plug syndrome shows a normal or dilated colon as compared to micro ...
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.
Diatrizoate is used in suspected intestinal perforation, meconium ileus, and to identify bowel-lumen communication. It should not be used to investigate tracheo-oesophageal fistula because it can cause pulmonary oedema when aspirated into respiratory system. Diatrizoate can dislodge sticky meconium by drawing water into intestines. [9]
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 ...
Ileus is a disruption of the normal propulsive ability of the intestine. It can be caused by lack of peristalsis or by mechanical obstruction. [1] The word 'ileus' derives from Ancient Greek εἰλεός (eileós) 'intestinal obstruction'. The term 'subileus' refers to a partial obstruction. [2]
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]
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.
