What are the X-ray findings of bowel obstruction?
X-ray findings may include: Dilated bowel – small bowel > 2.5 – 3 cm, cecum > 10 cm, transverse colon > 6 cm, sigmoid colon > 4cm. Gas and fluid in the bowel. Air-fluid levels in small bowel > 3 in number. Less gas and fluid in the bowel downstream of obstruction.
How can you tell the difference between sigmoid and cecal volvulus on X-ray?
Radiographic imaging can help differentiate between a sigmoid and cecal volvulus from other abdominal pathologies. For a cecal volvulus, an abdominal x-ray will reveal a dramatic dilation of bowel extending from the right lower quadrant moving upwards to the left upper quadrant of the abdomen (Figure 1).
What is the indication for operation for a plain abdominal findings of volvulus?
Inability to detorse the sigmoid volvulus endoscopically is an indication for immediate surgical intervention. If the patient has evidence of peritonitis or ischemic bowel, emergency surgery is indicated, and the operative procedure is chosen on the basis of intraoperative findings.
What are the signs of a twisted colon?
Symptoms of Sigmoid Volvulus
- abdominal cramping.
- bloody stools.
- constipation.
- nausea.
- signs of shock.
- vomiting.
What does a volvulus look like?
In the presence of a midgut volvulus, the twisted segment (usually a proximal segment) of small bowel has a characteristic corkscrew-like appearance on fluoroscopic images (Fig 7) (6).
How is an intestinal obstruction diagnosed?
Abdominal X-rays: Basic X-rays can sometimes show whether the small bowel is obstructed. Computed tomography (CT scan): A CT scan may be done to confirm a diagnosis and give more accurate information about the cause and the site of obstruction.
What is the best imaging for bowel obstruction?
Computed tomography is usually the most appropriate and accurate diagnostic imaging modality for most suspected bowel obstructions.
What is the difference between cecal and sigmoid volvulus?
Whereas sigmoid volvulus is usually an acquired condition, cecal volvulus is due to congenital incomplete dorsal mesenteric fixation of the cecum or ascending colon associated with an abnormally elongated mesentery distal to this area of absent mesentery.
What is the most common location of a volvulus?
The most common sites of volvulus are the sigmoid colon and cecum [1-4]. Volvulus of other portions of the alimentary tract, such as the stomach, gallbladder, small bowel, splenic flexure, and transverse colon, are rare.
