In cases of complete duodenal atresia, there is always a lack of bowel gas distal to the proximal duodenum. The cystic element tends to be smaller in CBA and sometimes the intrahepatic bile ducts dilate in an obstructed choledochal malformation. Below are the links to the authors’ original submitted files for images. 2008). 1. Zhou L, Guan B, Li L, Xu Z, Dai C, Wang W, Xia H, Xie X: Objective differential characteristics of cystic biliary atresia and choledochal cysts in neonates and young infants: sonographic findings. Radiographic imaging of a “double bubble” sign is characteristic of duodenal atresia (Figure 5) 5. Abdominal plain film shows a characteristic “double-bubble” sign, demonstrating the bubbles in the stomach and the dilated proximal duodenum; this confirms the … This is called the "double bubble" sign and usually indicates the presence of duodenal atresia. Fetal bowel dilatation is an indirect sonographic sign of mechanical or functional bowel obstruction. [9] On neonatal ultrasound, a double bubble can also be caused by a choledochal cyst, omental cyst, or enteric duplication cyst. The present study aimed to investigate the use of ultrasound and differential diagnosis to diagnose a fetal abdominal cyst.

Down syndrome: Jejuno-ileal atresia + + +/- + + + + Gas in stomach with no gas in colon: Stomach and proximal small intestine distension: Hypokalemia. Itoh Y, Hada T, Terano A, et al. Disease/Condition. This case highlights the need to be mindful of other important anomalies that can give this appearance and that may require early intervention. Ultrasonography findings are sufficient to make diagnosis; however, MRI helps to exclude multiple intestinal atresias which has different postnatal prognosis and management [4]. A management algorithm has been previously suggested in which confirming the cyst along with a non-dilated intrahepatic biliary tree and deranged liver biochemistry lead to urgent laparotomy and reconstructive surgery (Davenport and Hadzic 2003). The 'double bubble' sign on antenatal ultrasound is often associated with duodenal atresia although there are numerous causes. The main fetal sonographic features of duodenal atresia include a double‐bubble appearance due to a dilated stomach and proximal duodenum and hydramnios. differential diagnosis in pediatrics differential diagnosis in pediatrics von Dr. Ahmed D.

The table on the left lists the differential diagnosis for acute abdomen in the neonate. As you will have the opportunity to read below, the separation of the stomach from the duodenum is physiologically made by the pyloric valve, hence the double-bubble sign on the X-ray. Once the radiographic finding of a double-bubble sign without distal gas is determined, the diagnosis of duodenal atresia is evident, and usually no additional contrast-enhanced studies are needed. There is no gas in the bowel distal to the dilated duodenum. CBA, characterized by dilatation within an otherwise obliterated extrahepatic biliary tree, occurs in about 5% of large series and is detectable on maternal US (Davenport and Hadzic 2003; Caponcelli et al. Although his 20-week fetal anomaly scan had been normal, a maternal US scan at 36 weeks for high fundal height and suspected polyhydramnios showed the appearance of a “double bubble” (Figure 1), but without polyhydramnios. The double bubble sign is the classic radiographic finding of duodenal atresia, ... An extensive differential diagnosis exists in cases of suspected neonatal intestinal obstruction and the combination of the clinical history, physical examination, and radiologic evaluation is required for eventual diagnosis. Provide a differential diagnosis for a double bubble sign on plain films. An abdominal US identified a cystic structure measuring 38 mm in diameter in the region of the porta hepatis of uncertain aetiology (Figure 2). The diagnosis of duodenal atresia is usually confirmed by radiography. Caponcelli E, Knisely AS, Davenport M: Cystic biliary atresia: an etiologic and prognostic subgroup. By using this website, you agree to our Differential diagnosis of a dilated fetal stomach includes duodenal atresia or stenosis, malrotation with midgut volvulus, duodenal duplication, and antral duplication. Differential diagnosis. Jejunoileal atresia. Cookies policy. J Ultrasound Med 2012, 31: 833-841. Annular pancreas is the second most common cause of duodenal atresia. Abdominal plain film shows a characteristic “double-bubble” sign, demonstrating the bubbles in the stomach and the dilated proximal duodenum; this confirms the diagnosis . Postnatal ultrasound and MRCP confirmed a cystic lesion at the porta hepatis, mandating early laparotomy and a successful Kasai portoenterostomy. This showed a mucus-containing cyst which on intra-operative cholangiography (Figure 4) had a tenuous connection to a non-dilated irregular biliary tree. The “double bubble” sign represents the appearance of 2 gas-filled structures in the upper abdomen of newborns and infants on plain filmsof the abdomen (Figure 8). 1) Malrotation with midgut volvulus 2) Duodenal Atresia A male infant born at term was referred to our tertiary paediatric surgery centre at 2 days old with a history of bile-stained nasogastric aspirates. California Privacy Statement, Double-Bubble is also seen in duodenal atresia (typically diagnosed in newborn nursery) Differential Diagnosis. Privacy Imaging Differential. 40 Duodenal Stenosis (With Annular Pancreas) Partial duodenal obstruction in neonates is usually caused by duodenal stenosis, with or without annular pancreas. showed a clear relationship between age at portoenterostomy and clearance of jaundice in a series of 29 infants with CBA. A retrospective analysis of 41 cases of fetal abdominal cyst, which included ovarian cysts, choledochal cysts, intestinal duplication and mesenteric cysts, was performed. 10.1055/b-0038-166393 Part 2 Gastrointestinal Imaging Case 31Rebecca Stein-Wexler Fig. 7 … The ‘double bubble’ sign seen and originally described on plain radiography, but now also appreciable on US, is a result of fluid-filled structures seen in the either hypochondrium or epigastrium.
