Popis:	SummaryBackground The management of perianal Crohn's fistulas represents a significant challenge. A combination of medical and surgical therapy, guided by radiology, is often required. Aim To review systematically the literature to assess fistula healing rates with medical treatment (anti-TNF-α therapies ± immunomodulators) or surgical treatment alone, compared with combined medical and surgical treatment in fistulising perianal Crohn's disease (CD). Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Two independent reviewers searched the literature. Results Twenty-four articles were included. The total population was 1139 patients; 460 (40%) received single treatment with either medical or surgical therapy, and 679 (60%) received combined medical and surgical therapy. Eight studies compared single and combination therapy, with a total population of 797 patients (single therapy: n = 448, combination therapy: n = 349). In the single therapy group, 191/448 were in complete remission (43%). This was lower than the healing rate of the combination therapy group 180/349 (52%). No response to therapy was noted in 34% (153/448) of the single therapy group compared with 23% (80/349) of the combination group. Conclusions Combined surgical and medical (anti-TNF-α ± immunomodulators) therapy may have additional beneficial effects on perianal fistula healing in patients with Crohn's disease, compared with surgery or medical therapy alone. A well-designed Crohn's perianal fistula clinical trial is required in a multidisciplinary medical and surgical setting, with clearly defined end points of clinical (and likely patient reported outcomes) and radiological healing.
