Splenic flexure syndrome

Splenic flexure syndrome describes gas, bloating, and muscle spasms in the colon and or discomfort in the upper abdominal area.

It has been considered a type of IBS (Irritable bowel syndrome). The gas that is found in the colon is a mix between that which is swallowed and that which the intestine makes.  (1,2)

  • Radiologic exams will also show swelling in the area with gas or air being shown in the results.
  • Barium contrast studies have been proven to not be helpful in the diagnosis of splenic flexure syndrome.
  • A lower GI colonoscopy is a better way to look closely at the colon and its structures.

  • 24-hour diary of food intake
  • Differential diagnosis must rule out many possibilities. This is a limited list of the diagnosis or issues that must be ruled out: Constipation, herpes zoster, sickle cell crisis, splenic abscess, spleen hematoma, splenic infarct, kidney contusion, primary spleen sarcoma, spleen hematoma, subphrenic abscess, nonspecific splenetic, perinephric abscess, intestinal or bowel obstruction, kidney stones.  (2,3, 6)

What is Hepatic Flexure Syndrome?

The image above also shows the hepatic flexure. This syndrome has the same symptoms causes and treatments as the splenic flexure syndrome. The difference is that the gas build up is in the hepatic flexure, therefore, placing the pain and discomfort on the right side instead of the left.


What is a hepatic flexure polyp? A polyp is simply a tag of skin in an area that usually does not have one. In this case, the polyp would be noted in the hepatic flexure. This may cause problems with movement of feces through the colon.

What is a mobilization of splenic flexure? This is a laparoscopic technique used to better see and therefore diagnosis issues with the colon. It has been said that it helps to better view the mesenteric artery and the mesenteric windows. (9, 10)

Here is a video that shows the mobilization technique.

What is the hepatic flexure in the colon?

The hepatic flexure is the bend between the ascending and transcending colon. It lays near the liver which is where it got the name hepatic.

In conclusion splenic flexure syndrome is gas build up in the area of the colon called the splenic flexure. It is relieved by manipulation and anti-gas treatment. Many other diagnosis must be ruled out before giving this diagnosis to be sure the correct treatment is prescribed.
