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.
