Abstract:
BACKGROUND: Functional constipation (FC) might exert great influence on children in body and mental health, social-psychological development and long-term life quality. At present, there is not precise definition, clear classification, unite diagnostic standards and practicable systematic treatment project for FC in children. As a non-traumatic diagnostic means for chronic transiting constipation, gastrointestinal transit time (GTT) is considered as one of the objective indexes for dynamically observing gastrointestinal transit function, and has significance in the diagnosis of abnormal gastrointestinal dynamics, etiological investigation and therapeutic effect assessment.OBJECTIVE: To investigate the difference of GTT between constipation children and normal healthy control, so as to elicit its significance in assessing the dynamics of whole gastro-intestine and each segment.DESIGN: Case control comparative study based on FC children and healthy children.SETTING: Department of Pediatrics, Guangdong Provincial General Hospital, Chinese People's Armed Police Forces.PARTICIPANTS: This study was carried out at Pediatric Department of Guangdong Provincial General Hospital, Chinese People' s Armed Police Forces. Totally 28 children with confirmed FC in the General Hospital of Armed Police took part in the experiment, and 68 healthy children from a certain kindergarten and an elementary school in Guangdong province were selected as normal controls.METHODS: Whole gastrointestinal transit time(GTT), mouth-intestine transit time and colon transit time(CTT) were determined with plain abdominal photograph at 12 hours, 24 hours and 48 hours after orally administrated of radio-opaque markers.MAIN OUTCOME MEASURES: Whole GTT, mouth-intestine transit time and CTT, as well as right colonic transit time, left colonic transit time, rectosigmoid transit time.RESULTS: 50% whole gastrointestinal transit time, mouth-intestine transit time and CTT were[(23.6±1.6) vs (80.4±2.1) hours], [(9.9±1.4)vs(20.7±0.6) hours] and[(14.8±0.8) vs (59.9±2.3) hours] in constipation and healthy group respectively, with significant difference between them( P < 0.01 ) . Moreover there was statistical difference in right colon transit time, left colon transit time and rectosiqmoid transit time between two groups( P < 0.01).CONCLUSION: GTT of constipation children is obviously different from that of healthy children; it can be used for assessing the dynamics of whole gastrointestine and each segment, thereby possess practical significance in the diagnosis and therapeutic effect assessment of FC in children.Yang M, Wang BX, Wang MG.
