Ultrasound images of diseases of the gastro-intestinal tract:

1) Foreign body in the stomach:

Sonography of the stomach revealed a linear echogenic structure with posterior acoustic shadowing. On changing the probe angle the edge appears to be a semicircle. Plain X-ray of the abdomen revealed the structure to be coin (seen edge-on in the left hypochondrium). Images courtesy of Dr. Ravi Kadasne, UAE.

Here are the follow-up ultrasound scan and X-ray images of this patient, a young child. The coin, seen in the stomach (above images) has reached the caecum. (Images courtesy Dr. Ravi Kadasne).

Case-2:

Foreign body in GIT (X ray):

multiple pills in the GIT    X-ray of pills in GIT

This patient presented with abdominal pain and distension of abdomen. Plain X-ray abdomen show multiple radio-opaque objects in the stomach and small intestine. These x-ray appearances are consistent with foreign bodies (pills) in the GI tract. The patient had a history of taking tablets (pills) orally just before the X-rays. There is also evidence of intestinal obstruction. Note the gas distended small bowel and air fluid levels. Both images are courtesy of Shlomo Gobi, Israel.

 

2) Hypertrophic pyloric stenosis:

 

Pyloric stenosis in neonate:

ultrasound image of hypertrophic pyloric stenosis     ultrasound image shows proximity of the pylorus to the right kidney

nipple sign of hypertrophic pyloric stenosis

This neonate underwent sonography for persistent vomitting. Ultrasound images reveal a) marked thickening of the wall of the pyloric canal (5.5 mm.) b) elongation of the of the pyloric canal (the cervix sign) c) shifting of the pylorus bringing it in close proximity to the right kidney (antero-medial to right kidney) and gall bladder. d) distended stomach e) mucosal prolapse producing the antral nipple sign is also seen.

 

These ultrasound images thus suggest a diagnosis of hypertrophic pyloric stenosis. Sonographic images courtesy of Dr. V. Ganesan, Bahrain. Images taken using a Philips IU22 ultrasound machine.

Normal esophagus (also called oesophagus):

 

Sonography of the normal esophagus:

The normal esophagus (also spelt oesophagus or food pipe) is seen in this ultrasound image, in both transverse and longitudinal sections, to lie posterior to the left lobe of thyroid. Usually, the esophagus lies postero-medial to the left lobe. Sonography of the esophagus often reveals a prominent tubular structure, with the typical gut signature, as in this case. Here it lies posterior and appears rather flattened (side to side).

Jejunal obstruction:

Sonography of small bowel obstruction in neonate:

x-ray image of jejunal obstruction    jejunal obstruction in neonate (erect X-ray)

This neonate had severe vomiting and was unable to pass stool. Sonography of the abdomen showed multiple, distended loops of small bowel (jejunum) with collapsed thin large bowel (colon). X-ray images showed dilatation of the small bowel with multiple air fluid levels in the jejunum. There was no evidence of ascites. These ultrasound and X-ray images suggest a diagnosis of small bowel (jejunal) obstruction. The commonest cause of small bowel obstruction in fetus or neonate is meconium impaction (or meconium stones). Another important cause is jejunal atresia. This case is courtesy of Dr. Gunjan Puri, MD, India.
