A novel evaluation technique for measuring the distance between the anastomosis and intersphincteric groove via three-dimensional endoanal ultrasonography in children with Hirschsprung disease

Authors

Abstract

Background
This study aimed to describe our experience with three-dimensional endoanal ultrasonography (3D-EAUS) in patients who underwent surgery for Hirschsprung disease and to summarize the relationship between postoperative anal function and the distance between the anastomosis and intersphincteric groove (DBAI) measured via 3D-EAUS.
Results
We retrospectively reviewed patients with a history of undergoing surgery for Hirschsprung disease who visited our outpatient clinic between December 2018 and December 2019. All patients underwent 3D-EAUS for DBAI measurement. We used the Krickenbeck classification to evaluate postoperative anorectal function.
Conclusions
3D-EAUS enabled precise visualization of the anal anatomy and evaluation of the anastomosis. The DBAI was relatively short in patients with grade 3 soiling, although not significantly so. Further evaluation is warranted.
