The digestive system is a complex network that processes the food we eat. One crucial part of this system is the duodenojejunal flexure. Disorders in this area can lead to various health issues. This guide aims to explain these disorders in simple terms, helping you understand their causes, symptoms, and how they can be diagnosed and treated.
Anatomy of the Duodenojejunal Flexure
The duodenojejunal flexure is a critical point in the small intestine. It is the sharp bend where the duodenum (the first part of the small intestine) meets the jejunum (the second part). This flexure is located in the upper abdomen, just to the left of the midline, and is anchored by a muscle called the ligament of Treitz. This muscle helps support the intestines and plays a role in their movement.
Structure
The ascending portion of the duodenum ascends on the left side of the aorta, as far as the level of the upper border of the second lumbar vertebra. At this point, it turns abruptly forward to merge with the jejunum, forming the duodenojejunal flexure. This forms the beginning of the jejunum.[rx] The duodenojejunal flexure is surrounded by the suspensory muscle of the duodenum.[rx]: It is retroperitoneal, so is less mobile than the jejunum that comes after it, helping to stabilise the jejunum.[rx]
The duodenojejunal flexure lies in front of the left psoas major muscle, the left renal artery, and the left renal vein. It is covered in front, and partly at the sides, by peritoneum continuous with the left portion of the mesentery.
Types of Duodenojejunal Flexure Disorders
Several disorders can affect the duodenojejunal flexure. These include:
- Malrotation: An abnormal twisting of the intestines during fetal development.
- Volvulus: A condition where the intestine twists around itself, causing obstruction.
- Superior Mesenteric Artery (SMA) Syndrome: Compression of the duodenum between the SMA and the aorta.
- Obstruction: Blockage preventing food passage through the intestines.
- Inflammation: Swelling due to infection or autoimmune diseases.
- Tumors: Abnormal growths that may be benign or malignant.
- Diverticulitis: Inflammation of small pouches that can form in the intestinal lining.
- Ulcers: Sores on the intestinal lining that can cause pain and bleeding.
