Aims To assess the efficacy of anal fistula plug (AFP) procedure for the treatment of fistula‐in‐ano especially the complex fistulas. Method The database of PUBMED, MEDLINE, SCOPUS, EMBASE and COCHRANE LIBRARY for the period 1995–2009 was searched. A systematic analysis was carried to evaluate the success rate of AFP procedure in fistula‐in‐ano. Results A total of 25 studies were extracted and 12 ( n = 317) were finally included in the systematic review. The follow‐up period ranged from 3.5 to 12 months. The AFP procedure had a success rate (patient cure rate) ranging from 24% to 92%. In complex fistula‐in‐ano in prospective studies (8/12 studies), the success rate was 35–87%. The success rate in patients with Crohn’s disease was 29–86%. The success rate in the patients with single tracts was 44–93% and in patients with multiple tracts, success ranged from 20% to 71%. The abscess formation/sepsis rate was 4–29% (11/108) and the plug extrusion rate was 4–41% (42/232–19%). Conclusion Anal fistula plug procedure has a success rate ranging from 24% to 92% in different studies. In prospective studies of complex fistula‐in‐ano, there was a moderate success rate of 35–87%. As AFP is associated with low morbidity and sepsis, it appears to be a safe procedure. Further randomized controlled trials studying objective parameters of fistula healing are needed to substantiate these findings.
