Symptoms to Watch For
Doctors suspect sigmoid volvulus when patients report abdominal pain, nausea, and constipation, alongside a distended abdomen. Physical exams reveal a drum-like belly, and a CT scan confirms the suspicion by showing specific patterns in the colon.
Imaging Techniques
The abdominal CT scan is the go-to test, showing a 'whirl sign' or 'bird-beak' pattern of the twisted colon. In cases where a CT scan isn't available, an abdominal X-ray can reveal other signs, like a U-shaped distended colon, though it's less definitive.
Role of Blood Tests
While imaging is crucial, blood tests help rule out other conditions. They assess infection markers and organ function, ensuring no other underlying issues. These tests include checking blood cell counts and liver enzymes.
