Frontal view of the abdomen with double bubble sign, patient was found to have duodenal atresia. In radiology, the double bubble sign is a feature of pediatric imaging seen on radiographs or prenatal ultrasound in which two air filled bubbles are seen in the abdomen, representing two discontiguous loops of bowel in a proximal, or 'high,' small bowel obstruction.
The diagnosis of duodenal atresia is usually confirmed by radiography. An X-ray of the abdomen is the first step in evaluation. The x-ray should be obtained after placement of a nasogastric tube (feeding tube), evacuating the stomach and filling 40-50 ml of air [5] to demonstrate two large air filled spaces, the so-called "double bubble" sign.

Although the baby is exposed to radiation, an upper GI series (X-rays taken after the baby drinks a special contrast agent) can be diagnostic by showing the pylorus with elongated, narrow lumen and a dent in the duodenal bulb. [7] This phenomenon caused "string sign" or the "railroad track/double track sign" on X-rays after contrast is given ...
Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity.The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
The duodenal bulb is the site of duodenal ulcer occurrence. Duodenal ulcers are more common than gastric ulcers and - unlike gastric ulcers - are caused by increased gastric acid secretion. Duodenal ulcers are commonly located anteriorly, and rarely posteriorly. Anterior ulcers can be complicated by perforation, while the posterior ones bleed.
The "double bubble" pattern indicates that stomach torsion has occurred. X-ray from the underside of a dog with GDV. The dark area is the buildup of gas. Gastric dilatation volvulus (GDV), also known as gastric dilation, twisted stomach, or gastric torsion, is a medical condition that affects dogs and rarely cats and guinea pigs, [1] in which ...
These include mother-baby and SpyGlass cholangioscopes (to help in diagnosis by directly visualizing the duct as opposed to only obtaining X-ray images [13] [14] [15]) as well as balloon enteroscopes (e.g. in patients that have previously undergone digestive system surgery with post-Whipple or Roux-en-Y surgical anatomy).
