“…Plain abdominal radiography and upper gastrointestinal contrast-enhanced radiography will confirm duodenal obstruction. Diagnosis of annular pancreas is made on the basis of one of the imaging modalities, namely, sonography and computed tomography, or by endoscopic retrograde cholangiopancreatography (6). The first surgical treatment for an obstructive annular pancreas was performed by Vidal in 1905 (1).…”

Annular pancreas with duodenal stenosis and intestinal malrotation in two years girl: A case report

et al. 2014

Objective -To describe a rare case of a combination of annular pancreas with malrotation in early childhood. Case report -The patient is 2 year old aged girl with persistent non-bilious vomiting. She was vomiting several times a week, and over the ten days prior to presentation as many as several times a day. Upon presentation, the patient had an unremarkable abdominal exam with no abdominal pain. An upper gastrointestinal study showed extreme dilatation of the stomach and the duodenal bulb, and an abdominal computer tomography scan revealed an annular pancreas. Intra-operatively we find an annular pancreas and treated it by duodeno-duodenostomy, while the intestinal malrotation was treated by Ladd's procedure. Conclusion -Annular pancreas is a rare congenital anomaly which in childhood is related to duodenal atresia or stenosis and often affiliated with intestinal malrotation.

“…[3] More importantly, life-threatening duodenal obstruction or atresia are associated with more than 40% of annular pancreas cases. [4] Thus, if diagnosed antenatally, it represents a valuable predictor for future gastrointestinal emergencies and helpful in further management after birth.…”

Imaging pearls of the annular pancreas on antenatal scan and its diagnostic dilemma: A case report

Background: Annular pancreas is an uncommon cause of duodenal obstruction and rarely causes complete duodenal obstruction. Due to its rarity of identification in the antenatal period and overlapping imaging features with other causes of duodenal obstruction; it is often misdiagnosed. Case presentation: A 33-year-old primigravida came for routine antenatal ultrasonography at 28 weeks and 4 days of gestational age. On antenatal ultrasonography, dilated duodenum and stomach were seen giving a double bubble sign and a hyperechoic band surrounding the duodenum. Associated polyhydramnios was also present. Fetal MRI was also done. Postpartum ultrasonography demonstrated pancreatic tissue surrounding the duodenum. The upper gastrointestinal contrast study showed a non-passage of contrast beyond the second part of the duodenum. Due to symptoms of obstruction, the neonate was operated on, and the underlying cause was found to be the annular pancreas. Conclusion: Diagnosis of duodenal obstruction due to the annular pancreas is very important in the antenatal period to plan for appropriate therapeutic interventions after birth. A double bubble sign is seen due to various etiologies however the presence of a hyperechoic band in the antenatal ultrasound may point to the diagnosis of the annular pancreas.

“…In the vomiting infant, ultrasound may show narrowing of the 2 nd portion of the duodenum, with a surrounding ring of pancreatic tissue. The anomalous branch of the pancreatic duct may be seen on ultrasound coursing obliquely and to the right, anterior to the duodenum [21,22] .…”

Ultrasound is an invaluable imaging modality in the evaluation of pediatric gastrointestinal pathology; it can provide real-time evaluation of the bowel without the need for sedation or intravenous contrast. Recent improvements in ultrasound technique can be utilized to improve detection of bowel pathology in children: Higher resolution probes, color Doppler, harmonic and panoramic imaging are excellent tools in this setting. Graded compression and cine clips provide dynamic information and oral and intravenous contrast agents aid in detection of bowel wall pathology. Ultrasound of the bowel in children is typically a targeted exam; common indications include evaluation for appendicitis, pyloric stenosis and intussusception. Bowel abnormalities that are detected prenatally can be evaluated after birth with ultrasound. Likewise, acquired conditions such as bowel hematoma, bowel infections and hernias can be detected with ultrasound. Rare bowel neoplasms, vascular disorders and foreign bodies may first be detected with sonography, as well. At some centers, comprehensive exams of the gastrointestinal tract are performed on children with inflammatory bowel disease and celiac disease to evaluate for disease activity or to confirm the diagnosis. The goal of this article is to review up-to-date imaging techniques, normal sonographic anatomy, and characteristic sonographic features of common and uncommon disorders affecting the gastrointestinal tract in children.
