Abdomen

Abstract

In this chapter we discuss common and unusual conditions of the abdomen that are treated surgically, related to the stomach, small intestine and colon. Such as Hypertrophic pyloric stenosis, is one of the most common surgical conditions of the newborn. Congenital intestinal obstruction occurs in approximately 1 in 2000 live births and is a common cause of admission to a neonatal surgical unit. Normal rotation of the intestine requires transformation from a simple, straight alimentary tube into the mature fixed and folded configuration normally present at birth. Through precise embryologic events, the duodenojejunal junction become fixed in the left upper abdomen while the cecum is anchored in the right lower quadrant. The midgut, defined as the portion of the intestine supplied by the superior mesenteric artery (SMA), is thus suspended from a wide mesenteric base.
