Abstract
IntroductionThe diagnosis of Hirschsprung's disease (HD) relies on the histological demonstration of aganglionosis in the bowel wall. Biopsies may be obtained by rectal suction biopsy (RSB) or by transanal full-thickness excision biopsy (FTB). The objective of the present study was to evaluate the frequency of complications and inconclusive biopsies after FTB in children referred with suspicion of HD. The secondary objective was to calculate the frequency of proven aganglionosis. MethodsA retrospective chart review was performed of all patients under the age of 16years who underwent transanal FTB during the time period of 2008–2014. ResultsA total of 555 patients were included in the review. Inconclusive biopsies were found at the primary biopsy in 35 patients (5.9%). Aganglionosis was found in 12% of the cases. The complication rate was 6.6% (39 patients), 85% of which were classified as a Clavien–Dindo I–II and 15% were classified as Clavien–Dindo III. ConclusionsIn this retrospective evaluation of FTB for the diagnosis of HD, the frequency of inconclusive biopsies at primary attempt was low and the complication rate was relatively high. However, most were minor complications. Level of evidenceIII
