A duodenal web is a more rare cause of duodenal obstruction which tends to cause a windsock deformity of the duodenal lumen. It may also occur in adults. In most severe cases, there is significant tricuspid insufficiency with variable degrees of cardiomegaly. Introduction. In recessive disorders, the condition does not appear unless a person inherits the same defective gene for the same trait from each parent. Most such malformations must be surgically corrected soon after birth. Duodenal atresia or stenosis occurs when the intestine does not develop normally and leads to a blockage in the continuity of the intestine. This article will focus on ileal atresia alone but bear in mind that some cases correspond to jejunoileal atresia and show a mixed pattern, including the ones discussed in the jejunal atresia article. (For more information on this disorder, choose “Jejunal Atresia” as your search term in the Rare Disease Database.).

Blood vessel defects in the embryo may cause the absence or closure of the duodenum by decreasing the blood supply in the affected area, or there may be an overgrowth of cells in the duodenum that obstruct the channel of the first part of the duodenum (lumen) occuring during the sixth or seventh week of fetal development. After surgery, there is often some swelling in the operated area, which may make matters worse for a period of time. Jejunal obstruction may accompany intestinal malrotation, hernia or abdominal wall defects that strangle the small intestine, interrupting its blood supply. In duodenal atresia, there is complete obstruction of the duodenal lumen. Obstruction in the duodenum is known as duodenal atresia/stenosis and obstructions in the jejunum or the ileum are both called jejunoileal atresia/stenosis. The atresias typically involve: the shortest, widest part of the small intestine that joins the stomach (duodenum); one of the three portions of the small intestines that connects with the duodenum (jejunum); or the portion of the small intestine that opens into the large intestine (ileum), and the rectum. In Tricuspid Atresia, this septum generally has a hole in it, called a Ventricular Septal Defect, or VSD.

Auditory Canal Atresia or Stenosis Auditory canal atresia is a developmental absence of the external auditory canal. Choanal atresia is a congenital disorder where the back of the nasal passage is blocked, usually by abnormal bony or soft tissue (membranous) due to failed recanalization of the nasal fossae during fetal development.

Duodenal atresia is a complete occlusion or absence of the duodenal lumen, whereas duodenal stenosis refers to an incomplete obstruction caused by narrowing. Sonographically, pyloric atresia and stenosis are associated with a “single bubble” as opposed to the “double bubble” observed in duodenal atresia. www.pennhealth.com/ency/article/001131.htm. The signs and symptoms of adult pyloric stenosis are similar to those in the infant. All studies receiving U.S. government funding, and some supported by private industry, are posted on this government web site. Twenty to thirty percent of individuals affected with these disorders have Down syndrome and twenty-two percent have heart disease. Both conditions present with signs of obstruction, including a distended upper abdomen, delayed meconium passage, and vomiting. Parenteral nutrition (food given through a vein or directly to the stomach, but not by mouth) may be needed for a period of time. Bibliography. atresia | stenosis | As nouns the difference between atresia and stenosis is that atresia is (pathology) a condition in which a body orifice or passage in the body is abnormally closed or absent while stenosis is (medicine) an abnormal narrowing or stricture in a blood vessel or other tubular organ.
