DSA-guided pyloric balloon dilation versus conservative medical treatment for postsurgical gastroparesis syndrome / 介入放射学杂志

ABSTRACT

Objective To compare the clinical efficacy of DSA-guided pyloric balloon dilation with that of conservative medical treatment for postsurgical gastroparesis syndrome(PGS).Methods The clinical data of 41 patients with PGS,who were admitted to the Department of Interventional Radiology,Affiliated Third Hospital of Suzhou University of China to receive DSA-guided pyloric balloon dilation(study group,n=21)or conservative medical treatment(control group,n=20)between January 2012 and February 2021,were retrospectively analyzed.The median follow-up period in the control group and the study group was 626 days and 588 days respectively.The average length of stay(ALOS)was compared between the two groups.Results In the study group,all the 21 patients returned to normal food intake within 2 days after successful DSA-guided pyloric balloon dilation treatment,and they were all discharged within one week after treatment.The ALOS in the study group was(10.2±1.3)days,which was strikingly shorter than(34.5±14.2)days in the control group,the difference between the two groups was statistically significant(P＜0.001).Conclusion For the treatment of PGS,DSA-guided pyloric balloon dilation carries better clinical efficacy when compared with conservative medical treatment,therefore,it can be used as the preferred treatment for patients with PGS.Further studies are need to be conducted before its therapeutic mechanism can be clarified.
