Echocardiography/Ultrasound
- Echocardiography/ultrasound may be helpful in the diagnosis of toxic megacolon. Findings on an ultrasound suggestive of toxic megacolon include:
- Complete loss of haustra coli of the colon
- Hypoechoic and thickened bowel walls with irregular internal margins in the sigmoid and descending colon
- Marked dilation of the transverse colon (>6 cm), a finding that correlated well with the plain radiograph of the abdomen
- Hypoechoic and thin (< 2 mm) bowel walls without haustra coli in the dilated colon; in patients who underwent surgery, the postoperative pathohistologic findings of the bowel walls correlated with the ultrasonographic features observed before surgery
- Slight dilation of ileal bowel loops (diameter >18 mm) with increased intraluminal gas and fluid
