Jejuno- meaning

Jejuno- definitions

Overview of Jejuno

Jejuno is a term often used in medical contexts to refer to the jejunum, part of the small intestine. The small intestine is a crucial part of the digestive system, responsible for absorbing nutrients from food into the body. The jejunum specifically plays a vital role in this process, as it is where most nutrient absorption takes place.

Structure and Function of the Jejunum

The jejunum is located between the duodenum and the ileum in the small intestine. It is approximately 2.5 meters long in adults and is characterized by numerous folds and villi that increase its surface area for nutrient absorption. The walls of the jejunum contain millions of tiny projections called villi, which are lined with cells that absorb nutrients into the bloodstream.

Role in Nutrient Absorption

Jejuno plays a crucial role in the absorption of nutrients such as carbohydrates, proteins, fats, vitamins, and minerals. The villi in the jejunum have a large surface area and are equipped with specialized transporters that facilitate the uptake of these nutrients. Once absorbed, the nutrients are transported through the bloodstream to cells throughout the body, providing them with essential energy and building blocks.

Conditions Affecting the Jejunum

Several conditions can affect the jejunum and interfere with its normal function. These include inflammatory bowel diseases like Crohn's disease, infections, tumors, and malabsorption syndromes. Symptoms of jejunum-related conditions may include abdominal pain, diarrhea, bloating, and nutrient deficiencies.

Treatment of Jejunum Disorders

Jejuno disorders are typically diagnosed through imaging tests, endoscopy, and biopsy. Treatment depends on the underlying cause but may include medications, dietary changes, and in severe cases, surgery. Managing jejunum disorders effectively is essential to prevent complications and ensure the proper absorption of nutrients.

3. Jejuno-gastric reflux occurs when contents from the jejunum backflow into the stomach.
4. The surgeon performed a jejuno-jejunostomy to treat the bowel obstruction.
5. The patient underwent a jejuno-jejunostomy surgery for nutritional support.
6. Jejuno-ileal bypass surgery is sometimes used to treat morbid obesity.
7. The doctor ordered a jejuno-cecostomy to relieve the intestinal blockage.
8. The patient experienced symptoms of jejuno-colonic fistula following surgery.

10. Complications of jejuno-ileostomy can include leakage and infection.
