Plain abdominal radiographs do not always provide a definitive diagnosis. In cases of complete obstruction distented loops of intestine and a tubular soft tissue mass are usually obvious, but a partial obstruction will produce much more subtle signs which may be missed.

A barium enema or upper gastrointestinal contrast study can be useful in identifying the site of obstruction but may result in delay of treatment and should be used with care as leakage of contrast into the abdominal cavity will result in peritonitis.

Abdominal ultrasound can also be On a transverse section, a hyperechoic target mass in the centre with multiple hyperechoic and hypoechoic concentric ring is seen. On a longitudinal section, multiple hyperechoic and hypoechoic lines are seen. The intestines may also be hypomotile and proximal fluid accumulation can occur.
