What Is the Hepatic Flexure?

The hepatic flexure is the point of the colon where the liver touches the large intestine in the upper right abdomen, according to Three Rivers Endoscopy Center in Pennsylvania. The hepatic flexure marks where the colon turns at a 90-degree angle in the abdominal area.

When a doctor performs a colonoscopy from inside the large intestine, the hepatic flexure looks like a bluish, triangular shape on the camera image, notes TREC. The doctor cannot examine the liver from this point, but it serves as a landmark within the colon that lets the doctor know where the endoscope is within the organ.

The hepatic flexure is where the ascending colon, moving upwards, turns to take waste across the transverse colon, moving across the abdomen from right to left. One of the lowest points of the liver touches the colon at the hepatic flexure, according to WebMD.

The hepatic flexure is also called the right colic flexure, according to Reference.com. The colon removes salt, water and nutrients before forming stool with remnants from the small intestines. Bacteria line the colon to help the body remove waste materials. The large intestine has several muscles along its walls to move stool along before it reaches the rectum, as referenced in WebMD.
