BACKGROUND AND AIMS: Spontaneous @entity6177 formation is a common complication of @entity30 . @entity5173 [ @entity5173 ] may avoid surgery and preserve bowel length, although there is no consensus on its efficacy as the initial treatment and the associated outcomes if unsuccessful. This study uses meta-analytical techniques to compare the outcomes of @entity5173 alone versus primary surgery for Crohn's-related @entity6177 . METHODS: A comprehensive search for comparative studies examining the use of @entity5173 and surgery for spontaneous Crohn's-related @entity6177 was performed. Each study was reviewed and data extracted. Random-effects methods were used to combine data. RESULTS: There were six studies including a total of 333 @entity1 that met the inclusion criteria. Surgery was performed initially in 184 @entity1 , @entity5173 was performed in 149. Groups were similar in demographics and abscess characteristics. There was a significantly higher risk of @entity733 following @entity5173 (odds ratio [OR]: 6.544, 95% confidence interval [CI]: 1.783-24.010, p: 0.005]. The pooled proportion of @entity5173 @entity1 requiring subsequent surgery was 70.7%. There was no significant difference between approaches in post-procedural complication rate [OR: 0.657, 95% CI: 0.175-2.476, p: 0.535], ultimate permanent stoma requirement [OR: 0.557, 95% CI: 0.147-2.111, p: 0.389] or length of hospital stay [difference in means: -1.006 days, 95% CI: -28.762-26.749, p: 0.943]. CONCLUSIONS: @entity5173 can avoid surgery in up to 30% of @entity1 presenting with spontaneous @entity6177 . However, the suggested advantages over surgery in relation to complications and length of stay were not apparent. Further studies in this area are needed.
