Types of Intestinal obstruction

Intestinal atresia is a congenital (present at birth) malformation that involves the complete absence or closure of a part of the intestine. Intestinal stenosis is a narrowing of the intestine that causes partial blockage. Intestinal atresia is common in the duodenum, jejunum and ileum, which make up the small intestine and is rare in the colon. Intestinal atresia accounts for 33 percent of all cases of intestinal obstruction at birth.
