Comparison of Barium Enema and frozen section results in the diagnosis of Hirschsprung's Disease in a tertiary care hospital at Aceh, Indonesia

Abstract

Introduction: Hirschsprung's Disease (HD) also called congenital aganglionic megacolon is a disorder caused by undeveloped distal to proximal intestinal nerve ganglion cells. Diagnosis includes determining the aganglionic segment through barium enema radiology examination and histopathology of frozen section with permanent section as gold standard. Determining the diagnostic value of this modality is important for operative management decision.

Materials and methods: The study was a retrospective, cross-sectional study with diagnostic test design. Patient data were obtained in the form of clinical symptoms, barium enema, and frozen section expertise were assessed for the suitability of the diagnostic value by referring to the permanent section as the gold standard.

Result: Thirty-four patient data were obtained. The sensitivity, specificity, and accuracy of barium enemas were 95%, 69.2%, and 82%, respectively. The values of sensitivity, specificity, and accuracy of frozen section were 95%, 92.8%, and 88%, respectively. The Cohen-Kappa statistic value was 0.62 (good agreement).

Conclusion: Accuracy of FS is better than barium enema in diagnosing HD. In health care center with limitation of histopathological facility, BE could be used as the alternative procedure as interrater comparisons showed good agreement. Therefore, either frozen section or barium enema can be carried out in common or in separate term.
