Clinicopathologic features of intestinal dysganglionosis in children / 临床儿科杂志

ABSTRACT

ObjectiveTo investigate the clinical and pathological features of Hirschprung disease (HD), intestinal neuro-nal dysplasia (IND) and hypoganglionosis (IH) in children.MethodsThe clinical data and pathologic slices from 238 children with intestinal dysganglionosis were retrospectively analyzed. The age, sex, involved intestinal length of children and prognosis were compared.ResultsIn 238 patients, 138 (58.0%) were diagnosed by rectal mucosal biopsies. There were 122 HD patients whose median age at diagnosis was 9 months and the ratio of male to female was 4.31, without involvement of whole colon. There were 45 IND patients whose median age at diagnosis was 14 months and the ratio of male to female was 1.051, and the whole colon of 33.3% patients was involved. There were two male IH patients whose ages at diagnosis were 12 years and 18 years respectively, and their whole colon was involved. There were 59 patients with HD complicated by IND whose median age at diagnosis was 13 months and the ratio of male to female was 5.561 and the whole colon of 16.9% patients was involved. There were 10 male patients with HD complicated by IH whose median age at diagnosis was 11.5 months and the whole colon of 80.0% patients was involved. The ages at diagnosis, the sex ratio, the rates of whole colon involved, and the cure rates among 5 groups were signiifcantly different (allP<0.01).ConclusionsThe rectal mucosal biopsy was the main method in diagnosis of intestinal dysganglionsis in children. Patients with HD had higher incidence and mild condition and favorable prognosis. Patients with IH or patients with HD complicated by IH had lower incidence rates and severe condition and poor prognosis, followed by patients with IND or patients with HD complicated by IND.
