Therapeutic Effects Of Peroral Catheter Balloon Dilatation Therapy For Cricopharyngeal Achalasia After Brainstem Stroke

ObjectivesTo investigate the effects of peroral catheter balloon dilatation on patients with dysphagia caused by cricopharyngeal achalasia after brainstem stroke and observe the related complications and adverse reactions to provide guidance for clinical treatment.MethodsForty-two stroke survivors with cricopharyngeal achalasia were randomly divided into a control and a treatment group,22 cases in the treatment group and 20 cases in the control group.Both groups of patients received basic medical treatment and routine dysphagia rehabilitation therapy,while the treatment group was additionally given peroral catheter balloon dilatation therapy.The swallowing function of both groups were evaluated with Functional Oral Intake Scale(FOIS)and videofluoroscopic swallow study(VFSS)before and after the two-week treatment.Everytime after the peroral catheter balloon dilatation therapy,the occurrence of complications such as mucosal bleeding,laryngeal edema,and pain was observed in the treatment group.ResultsThere was no significant difference in FOIS scores,videofluoroscopic swallowing scores,and pharyngeal transit time between the two groups(P>0.05),and they were comparable.After the treatment,FOIS scores of both groups increased significantly(P<0.05),the scores of treatment group(5.68±0.72)increased more significantly than the control group(3.32 ± 0.83)(P<0.05).Videofluoroscopic swallowing scores of both groups increased(P<0.05),while the mean score of treatment group(8.45±0.96)significantly increased more than that of the control(5.33±1.12)(P<0.05).The mean time for the bolus passing the pharynx was significantly shortened from 0.26 s to 0.15 s in the treatment group(P<0.05),but no significant difference was found in the control group(P>0.05).In the treatment group,there were 0 case of mucosal bleeding and 1 case of laryngeal edema,and the mean pain score was 1.9±1.1.ConclusionPeroral catheter balloon dilatation is effective for relieving cricopharyngeal achalasia after brainstem stroke,and the complications are few and light,so it is worthy of clinical application.
