How is a small bowel obstruction diagnosed?
Accordingly, what is the most common cause of small bowel obstruction?
Small-bowel obstruction (SBO) is caused by a variety of pathologic processes. The most common cause of SBO in developed countries is intra-abdominal adhesions, accounting for approximately 65% to 75% of cases, followed by hernias, Crohn disease, malignancy, and volvulus.
One may also ask, what are the symptoms of partial bowel obstruction? Symptoms of small bowel obstruction may include the following:
- Abdominal (stomach) cramps and pain.
- Malaise (an overall feeling of illness)
- Lack of appetite.
- Severe constipation. In cases of complete obstruction, a person will not be able to pass stool (feces) or gas.
One may also ask, can a small bowel obstruction resolve on its own?
An intestinal blockage is a potentially serious medical condition. A complete intestinal blockage is a medical emergency and often requires surgery. Sometimes, a partial blockage may resolve on its own.
What is the pathophysiology of a small bowel obstruction?
Small-bowel obstruction (SBO) leads to proximal dilatation of the intestine due to accumulation of gastrointestinal (GI) secretions and swallowed air. This, in turn, leads to increased peristalsis above and below the obstruction, with frequent loose stools and flatus early in its course.
