Conclusion

Ultrasound is not a screening method for intraluminal structures, because air within the bowel can obscure lesions. However sometimes intraluminal stuctures like polyps and carcinomas can be found Also sometimes foreign bodies and roundworms can be seen. In the second patient the diagnosis unfortunately could not be confirmed. She never had a tube placed. No foreign body could be retreived and the stucture was not visible on a CT scan made the same day. The patient had not been abroad making a roundworm unlikely.
