The patient has a small bowel obstruction, likely due to adhesions from prior surgery, evident clinically and confirmed by radiograph (grossly dilated small bowel without distal colonic dilation to suggest paralytic ileus). Conservative treatment in a stable patient involves NG tube decompression and NPO. A CT can be obtained for further characterization and to look signs of bowel compromise (and would be in real life), but there is no reason to delay appropriate care to get it.
