Duodenojejunal flexure obstruction is a medical condition where the passage between the duodenum and the jejunum (parts of the small intestine) becomes blocked. This blockage can cause severe digestive problems and requires prompt medical attention. Understanding this condition can help in early detection and treatment.
Anatomy of the Duodenojejunal Flexure
The duodenojejunal flexure is the junction where the duodenum meets the jejunum:
- Duodenum: The first part of the small intestine immediately after the stomach.
- Jejunum: The middle section of the small intestine that continues from the duodenum.
- Flexure: A bend or curve, in this case, where the duodenum turns into the jejunum.
This area is critical for nutrient absorption and digestion.
Types of Obstruction
- Partial Obstruction: The passage is narrowed but not completely blocked.
- Complete Obstruction: The passage is entirely blocked, preventing any content from passing through.
- Mechanical Obstruction: Physical blockage due to tumors, adhesions, or foreign bodies.
- Functional Obstruction: The muscles or nerves controlling the intestine do not work properly.
- Acute Obstruction: Sudden onset of blockage.
- Chronic Obstruction: Blockage develops over time.
- Intrinsic Obstruction: Blockage from within the intestine.
- Extrinsic Obstruction: Blockage caused by external pressure on the intestine.
