Untwisting the complexity of midgut malrotation and volvulus ultrasound.

Pediatr Radiol 2021 Apr 4;51(4):658-668. Epub 2021 Jan 4.

Singleton Department of Radiology, Texas Children's Hospital, 6701 Fannin St., Houston, TX, 77030, USA.

Abdominal US is emerging as an alternative to the upper gastrointestinal (GI) series as the preferred diagnostic imaging test for midgut malrotation complicated by volvulus. Unlike the upper GI series, US is free from ionizing radiation, does not require oral contrast agent, and can be performed portably and at times remotely from the interpreting radiologist, expediting diagnosis. Although some institutions do not have a standardized US protocol for midgut volvulus, many routinely use US in the setting of an infant or child with acute abdominal signs or symptoms to evaluate for common conditions such as hypertrophic pyloric stenosis, intussusception, necrotizing enterocolitis and appendicitis.

ACR Appropriateness Criteria® Vomiting in Infants.

J Am Coll Radiol 2020 Nov;17(11S):S505-S515

Specialty Chair, Riley Hospital for Children Indiana University, Indianapolis, Indiana.

Vomiting in infants under the age of 3 months is one of the most common reasons for parents to seek care from their doctor or present to an emergency room. The imaging workup that ensues is dependent on several factors: age at onset, days versus weeks after birth, quality of emesis, bilious or nonbilious vomiting, and the initial findings on plain radiograph, suspected proximal versus distal bowel obstruction. The purpose of these guidelines is to inform the clinician, based on current evidence, what is the next highest yield and most appropriate imaging study to pursue a diagnosis. Read More
