摘要：
Purpose: Perianal fistulas, and specifically high perianal fistulas, remain a challenge for surgical treatment. Many techniques have been and are still being developed to improve the outcome after surgery. A systematic review and meta-analysis was performed for surgical treatment of high cryptoglandular perianal fistulas. Methods: Medline (Pubmed, Ovid), Embase and The Cochrane Library databases were searched for relevant randomized controlled trials on surgical treatments for high cryptoglandular perianal fistulas. Two independent reviewers selected articles for inclusion based on title, abstract and outcomes described. The main outcome measurement was the recurrence/healing rate. Secondary outcomes were continence status, quality of life and complications. Results: The number of randomized trials available was low. Fourteen studies could be included in the review. A meta-analysis could only be performed for the mucosal advancement flap versus the fistula plug, and did not show a result in favour of either technique in recurrence or complication rate. The mucosal advancement flap was the most investigated technique but did not show any advantage over any other technique. Other techniques identified in randomized studies were seton treatment, medicated seton treatment, fibrin glue, autologous stem cells, island flap anoplasty, rectal wall advancement flap, ligation of the intersphincteric fistula tract, sphincter reconstruction, sphincter-preserving seton and techniques combined with antibiotics. None of these techniques seemed superior to each other. Conclusions: The best surgical treatment for high cryptoglandular perianal fistulas could not be identified. More randomized controlled trials are needed to find the best treatment. The mucosal advancement flap is the most investigated technique available. © 2016, The Author(s).
