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.

Abdominal ultrasound will reveal a cylindrical mass with layering of the intestinal wall. 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 the intestine proximal to the obstruction may be distented with fluid.  

 

This can be used to identify ileocolic or caecocolic intussusception.

 

Intussusception can occur in the [[Small Intestine - Anatomy & Physiology|small intestine]], [[Caecum - Anatomy & Physiology|caecum]] or [[Colon - Anatomy & Physiology|colon]].
