Diagnosis is made on the above clinical signs and a combination of confirmatory tests. Large volumes of nasogastric reflux may be obtained; greater than 2L of fluid with a pH greater than 5 is considered abnormal. Rectal examination may indicate multiple distended loops of small intestine, a finding that usually indicates the need for surgical intervention.

Large volumes of nasogastric reflux may be obtained; greater than 2L of fluid with a pH greater than 5 is considered abnormal. Rectal examination may indicate multiple distended loops of small intestine, a finding that usually indicates the need for surgical intervention. Ultrasonographic examination often reveals a distended, oedematous, fluid-filled small intestine proximal to the strangulated segment. The intestinal wall is hypoechoic and peristaltis may be absent.
