Colic flexures

From WikiMD's Wellness Encyclopedia

(Redirected from Colic flexure)

Colic flexures are significant anatomical landmarks in the large intestine of the human body. They are bends in the colon that divide it into different segments. There are two main colic flexures: the hepatic flexure and the splenic flexure. These flexures play a crucial role in the movement and processing of waste material through the digestive system.

Hepatic Flexure[edit | edit source]

The hepatic flexure, also known as the right colic flexure, is located near the liver, which explains its name (hepatic relates to the liver). It marks the junction where the ascending colon turns to become the transverse colon. This flexure is situated in the right upper quadrant of the abdomen, just below the liver. The hepatic flexure is an important landmark for surgeons and radiologists as it can be a site for colonic obstruction and other gastrointestinal issues.

Splenic Flexure[edit | edit source]

The splenic flexure, or left colic flexure, is found near the spleen, hence its name. It represents the point where the transverse colon turns downward to become the descending colon. Located in the left upper quadrant of the abdomen, the splenic flexure is noted for being the highest point of the colon. Due to its sharp bend and the fact that it is a gravity-dependent area, the splenic flexure can be a site for the accumulation of fecal material, leading to splenic flexure syndrome, characterized by gas and bloating.

Clinical Significance[edit | edit source]

Both colic flexures are of clinical significance due to their roles in the passage of fecal matter and their potential involvement in various gastrointestinal conditions. Conditions such as colonic volvulus, colorectal cancer, and diverticulitis can affect the colic flexures. Their anatomical positions also make them critical landmarks in abdominal surgeries and diagnostic procedures like colonoscopy.

Diagnosis and Treatment[edit | edit source]

Diagnosis of conditions related to the colic flexures often involves imaging studies such as CT scans, MRIs, and X-rays, in addition to colonoscopy. Treatment varies depending on the underlying condition but may include dietary changes, medications, or surgery.
