Umbilical region

Umbilical region is the central region of the abdomen, named for its proximity to the umbilicus (navel). It is one of the nine regions of the abdomen, which are used to help locate abdominal structures and diagnose abdominal pain.

Anatomy

The umbilical region is surrounded by several other regions of the abdomen. These include the epigastric region above it, the hypogastric region below it, and the lumbar regions to its left and right.

The umbilical region contains several important structures. These include part of the small intestine, specifically the jejunum and ileum, as well as the transverse colon of the large intestine. The greater omentum, a large apron-like fold of visceral peritoneum, also hangs down from the stomach and overlays the intestines in this region.

Clinical significance

Due to the number of structures in the umbilical region, pain in this area can be a sign of various conditions. These include appendicitis, gallstones, peptic ulcer disease, and pancreatitis. In addition, the umbilical region is often the site of hernias, specifically umbilical hernias, which occur when part of the intestine or fatty tissue bulges through the abdominal wall near the navel.
