Objective: To evaluate the safety

efficacy and degree of comfort of refluence clysis by automatic coloclyster machine in children with congenital megacolon disease

and compare the findings with the traditional clyster.Methods: 56 children with congenital megacolon disease(common type) were divided into experiment group(refluence clysis by automatic coloclyster machine) and control group(traditional refluence clysis)at random.Before and after the last refluence clysis

the electrolytes and osmotic pressure in blood

plasma protein

body weight were detected

and the colony in stool was counted.Moreover

the comfort degree in elder children and effects of refluence clysis were evaluated

and the time of coloclysis and defecation after operation

hospital days and incidence of complications were observed.Results:(1) In experimental group

the weight and plasma-albumin level of children were increased and number of the colony in stool was decreased significantly(P<0.05).(2) In experimental group

the electrolytes and osmotic pressure in blood were stable before and after refluence clysis(P>0.05).(3) There were no significant deviation on the time of coloclysis and defecation after operation and incidence of complications(P>0.05).However

comfort degree and effects of refluence clysis by automatic coloclyster machine were significant improved than those by traditional refluence clysis

and length of hospital stay in experiment group was shortened(P<0.05).Conclusion: Convenience

saving time

high comfort degree

safety and better effects are the significant merits of the refluence clysis by automatic coloclyster machine

which could be used widely in children with congenital megacolon disease.
