What Is the Hepatic Flexure? | The Colon Bend You Should

The hepatic flexure is the sharp bend where the ascending colon turns into the transverse colon.

“Hepatic” means liver, which is why this part of the colon sounds like it belongs to a different organ system entirely. If you’re looking at a diagram of the digestive tract and spot a sharp bend tucked up under the right rib cage, that’s the hepatic flexure — and it’s pure large intestine, not liver tissue.

The honest answer: the hepatic flexure (also called the right colic flexure) is the 90-degree turn where the ascending colon becomes the transverse colon. It sits right below the liver, which explains the name, but its job and its problems belong to the colon. This article walks through where it is, what it does, and the symptoms that can point to trouble at that specific bend.

Where It Lives in Your Abdomen

The colon travels in a rough inverted-U shape through the abdominal cavity. Food waste moves up the right side through the ascending colon, then makes a tight turn near the liver to head horizontally across the belly as the transverse colon. That tight turn is the hepatic flexure.

A 2022 review in Clinical Anatomy examined the terminology for these large intestine bends and confirmed the hepatic flexure as the most important landmark on the right side, with the splenic flexure as its counterpart on the left. The spot is also a key reference point during colonoscopy — gastroenterologists know they’ve reached the flexure when the scope passes that sharp corner under the liver.

Anatomy at a Glance

The flexure sits just below the liver’s right lobe and above the right kidney. It’s held in place by the coronary ligament and the hepatocolic ligament — connective tissue sheets that anchor the colon to surrounding organs. That positioning matters because pain or inflammation here can mimic gallbladder or kidney problems.

Why the Name Confuses People

Most people hear “hepatic” and think liver. That’s reasonable — the word comes directly from the Greek hēpar (liver). But the hepatic flexure isn’t part of the liver at all; it’s simply the colon bend that sits closest to it. The naming describes location, not tissue type.

Common questions people have when they first learn the term:

• Does the hepatic flexure belong to the liver? No. It’s a colonic structure that happens to sit adjacent to the liver’s lower edge. The two organs share a neighborhood but not a function.
• Is hepatic flexure pain the same as liver pain? Not always. Pain near the hepatic flexure can come from gas, stool, or inflammation inside the colon. Liver pain typically involves the organ itself — hepatitis, gallstones, or fatty liver disease.
• Can you feel the hepatic flexure? Not directly under normal conditions. But when the colon is distended with gas or stool, some people report a dull ache or pressure below the right ribs that may be traced to the flexure.
• Why does it matter for colonoscopy? The hepatic flexure is a routine landmark during screening. Difficulty passing the scope through this turn can indicate adhesions, inflammation, or a tortuous colon anatomy.
• Does everyone have one? Yes — the hepatic flexure is a standard anatomical feature present in virtually everyone, though its exact angle and position vary slightly from person to person.

For those being told they have “hepatic flexure polyps” or “hepatic flexure diverticulitis,” the naming confusion adds unnecessary worry. It’s standard colon geography, not a separate liver diagnosis.

The Hepatic Flexure and Its Left-Side Twin

The colon has two major bends — one on the right (hepatic flexure) and one on the left (splenic flexure). The left-side bend sits near the spleen, which is why it carries that name. Per Cleveland Clinic’s Splenic Flexure Definition, that bend is where the transverse colon turns downward into the descending colon. Together, the two flexures frame the top of the colon’s inverted-U shape.

The clinical significance of each flexure differs. The hepatic flexure is a known location for right-sided colon cancers, which are more common in older adults and often have different molecular profiles than left-sided tumors. The splenic flexure is a classic site for the “splenic flexure syndrome,” where trapped gas produces sharp left-upper-quadrant pain that sometimes radiates to the chest or shoulder.

Understanding which flexure is involved helps narrow down possible causes. A 2022 study in the journal Clinical Anatomy reviewed the terminology for the flexures of the large intestine, noting that the most important are the right (hepatic) and left (splenic) flexures — they serve as the primary structural landmarks for surgical planning and colonoscopy navigation.

What Can Go Wrong at the Hepatic Flexure

The flexure is a normal part of colon anatomy, but certain problems can develop there. Because it’s a tight corner, stool can slow down slightly at this junction, which may contribute to several conditions.

1. Hepatic flexure diverticulitis. Diverticulitis in this location is infrequent — about 5 to 10% of all diverticulitis cases in the large intestine. When it does occur, it can mimic gallbladder inflammation and may be misdiagnosed without imaging.
2. Colon cancer at the flexure. Tumors can develop at the hepatic flexure. An extended right hemicolectomy is a standard surgical option to remove tumors located in this region. Synchronous (multiple) tumors at the hepatic flexure have been documented in case reports, presenting with abdominal distension and pain.
3. Colonic obstruction. A blockage can occur at the hepatic flexure from a tumor, a bezoar (a mass of undigested material), or severe inflammation. Symptoms include cramping pain, bloating, vomiting, and inability to pass gas or stool.
4. Gas trapping. Some people experience pain at the hepatic flexure when gas builds up at that bend. The pain may be continuous or intermittent and is often partly relieved by defecation — which distinguishes it from liver pain.

When pain occurs over the hepatic flexure, gallbladder disease is often suspected because of the proximity. Imaging — typically a CT scan or colonoscopy — helps tell the difference. If severe abdominal pain develops, contacting a doctor promptly is important since bowel obstruction can worsen quickly.

When Pain Points to Hepatic Flexure Problems

Pain near the hepatic flexure can be tricky to sort out. The flexure sits next to the liver, gallbladder, and right kidney, as NCI notes in its located near the liver reference — so pain in that general area has several possible sources. The character and timing of the pain offer clues.

Pain from the hepatic flexure itself tends to be crampy or pressure-like, often coming and going in waves. It may improve after passing gas or having a bowel movement. If the pain is sharp, constant, or radiates to the right shoulder, the cause is more likely the gallbladder or liver rather than the colon.

Signs of a more serious problem — such as a bowel obstruction at the flexure — include severe cramping pain that comes in waves, vomiting, abdominal swelling, and the inability to pass gas or have a bowel movement. These symptoms require immediate medical evaluation.

The Bottom Line

The hepatic flexure is a normal bend in your colon — not a liver condition, not a hidden disease. It’s simply where the ascending colon turns into the transverse colon under your right rib cage. Most people never think about it until pain or a screening exam puts it on the radar. If you do feel discomfort in that area, knowing the bend exists helps narrow down whether the colon or the nearby organs are the source.

If you experience persistent or worsening pain below your right ribs, a gastroenterologist or your primary care doctor can help distinguish between colonic issues at the hepatic flexure and problems with your gallbladder or liver — two very different sets of conditions that share a zip code in your abdomen.
