A 65-year-old male patient presented with constipation and pain in the abdomen. The patient had a previous history of abdominal surgery.

The patient was sent to the radiology department for ultrasonography. Multiple dilated bowel loops were found on ultrasonography. On plain x-ray of the abdomen in an erect posture, we found multiple air-fluid levels in the central abdomen with a relative paucity of bowel gas distally, confirming the diagnosis of intestinal obstruction.
