title: Comparison of strictureplasty and endoscopic balloon dilatation for stricturing Crohn's disease--review of the literature.
abstract: BACKGROUND
  Stricturing Crohn's disease is accompanied by a high-risk for bowel resection and subsequent short bowel syndrome. Strictureplasty (SP) and endoscopic balloon dilatation (EBD) have been developed to prevent, or at least delay, the requirement for resection. The goal of this study was to compare the outcome of these two procedures with regard to complications and disease recurrence.
  
  
  METHODS
  We conducted a MEDLINE literature search to give a current overview about the safety and efficacy of EBD and SP.
  
  
  RESULTS
  The initial search yielded 744 articles. Case reports, reviews and meta-analyses were excluded. Finally, 63 articles (SP, 40 articles; EBD, 23 articles) were used for the review. None of the studies compared the two methods directly. A total of 2,532 patients (SP, n = 1,958; EBD, n = 574) were included. The incidence of perioperative complications after SP was 11% and the incidence of major complications was 5%. The median surgical recurrence rate was 24% after a median follow-up of 46 months. The median technical success for EBD was 90%. Major complications occurred in 3% of the cases. According to an intention-to-treat protocol, the median surgical recurrence rate was 27.6%. Per-protocol analysis revealed a median surgical recurrence rate of 21.4% after a median follow-up of 21 months.
  
  
  CONCLUSIONS
  Due to the lack of comparable data, there is currently no reliable information on whether one treatment option is superior to the other. Regarding the limited applicability of EBD in strictures of the small bowel, only a controlled trial would provide evidence as a basis for clinical decision making in CD strictures that are potentially treatable by EBD and SP.
