Final answer:
Small bowel obstruction (SBO) can have various causes, including adhesive SBO, incarcerated hernia, tumors, and intestinal volvulus.
Step-by-step explanation:
Small bowel obstruction (SBO) can have various causes, including:
- Adhesive SBO: Adhesions are bands of fibrous tissue that can form after surgery or inflammation. They can obstruct the small intestine, leading to symptoms such as abdominal cramps and constipation.
- Incarcerated hernia: A hernia can become trapped and cause a blockage in the small bowel. This can result in abdominal pain, cramping, and constipation.
- Tumors: Benign or malignant tumors in the small intestine can obstruct the passage of food and fluids, causing cramps, vomiting, and weight loss.
- Intestinal volvulus: This occurs when the small intestine twists on itself, leading to a mechanical obstruction. Symptoms include severe abdominal pain and cramping, vomiting, and constipation.
