Abstract

Background

Intestinal malrotation and particularly volvulus are potentially devastating conditions. Upper gastrointestinal (UGI) contrast studies have been considered the gold standard for diagnosis. However the use of ultrasonography (US) has been increasingly described. We describe a method for delineating the duodenal anatomy with US as a means to exclude malrotation.

Objective

To report our experience using US to assess intestinal rotation.

Materials and methods

We conducted a retrospective audit of US scans performed at a tertiary referral centre to exclude malrotation for paediatric surgery between 2008 and 2011.

Results

One hundred thirty-nine infants were included, of whom 114 had a normal US scan. Of the 114, nine had subsequent upper gastrointestinal contrast studies that confirmed the initial results; there were no false-negatives. There were abnormal US scans in four infants associated with midgut volvulus and malrotation; there were no false-positives. The other 21 US scans were equivocal, and 11 of these had a confirmatory UGI contrast study; only one required surgery to correct malrotation.

Conclusion

US has been a safe and effective tool in the assessment of intestinal rotation at our institution. The main advantages of US imaging are its lack of ionising radiation and its rapid and accurate diagnosis of volvulus.
