Résumé
Objective To investigate the efficacy of low-dose retention enema for treating ulcerative colitis.Methods Eighty patients diagnosed with chronic recurrent ulcerative colitis were randomly divided into control group and observation group with equal number.The retention enema was used in the control group and the improved retention enema was used in the observation group. Enema was done once every night,10 days as a course of treatment in both groups.The two groups were compared in terms of liquid retention time,curative effect after two courses and patients’satisfaction degree with enema.Results The liquid retention time in the intestinal lumen in the observation group was significantly longer than that of the control group.The efficacy was significantly better than the control group.Patients satisfaction with enema in the observation group was significantly higher than that of the control group (P<0.05).Conclusions The improved low-dose liquid enema is effective in the treatment of ulcerative colitis for its liquid retention time in the intestines.It is effective,comfortable,convenient,and likely to be accepted by patients.
