Abstract:
Objective To evaluate the effectiveness and safety of double balloon enteroscopy( DBE) in retrieval of retained capsule and identify the factors associated with successful retrieval. Methods A total of 23 consecutive retention cases who received retrieval of retained capsules by DBE from January 2010 to December 2013 were reviewed. They were assigned to success group and failure group. The differences in insertion route, insertion depth, lesion location between the two groups were analyzed. Results Fifteen cases of all 23 retention cases were successfully retrieved and the success rate was 65?2%. There was no significant difference in the mean entrapped period of CE between the two groups [20?0(15?0,57?0)d VS 21?0(16?0,240?0) d,P=0?525]. DBE via oral route exhibited remarkable higher success rate than anal route [ 71?4%( 15/21) VS 0/5, P=0?007] . Compared with ileum, it was easier to take out CE located at jejunum( 8/8 VS 7/13, P=0?046 ) and the insertion depth was significantly less in the success group [(167?3±33?8)cm VS (258?3±23?9) cm, P=0?041]. Whether the capsule was in pelvic cavity shown by x?ray film before the surgery was irrelevant to the successful rate(9/14 VS 5/6,P=0?613) and insertion depth of the DBE on access to the capsule[(132?0±68?6) cm VS (200?0±40?3) cm, P=0?376],or to the actual location of the capsule. Conclusion Peroral DBE is an effective method for removal of retained CE and the success rate isn′t relevant to the entrapped period. Retained CE locates in ileum and jejunum is more difficult to be taken out than in duodenum.
