Article in Techniques in coloproctology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04660903 (Treatment of Fistula in Ano With Autologous Fatty Tissue Cells Transplantation), which is not on this map.

1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundInjection of autologous fat is an established method within plastic surgery for soft tissue augmentation. The aim of the present study was to determine whether transperineal fat graft injection could promote healing of anovaginal fistulas.

methodsThe procedures were performed at the University Hospital of North Norway, Tromsø, Norway, and at Aarhus University Hospital, Aarhus, Denmark, between May 2009 and September 2016. After abdominal liposuction, fat was injected around the fistula tract that was finally transected percutaneously with a sharp cannula and fat injected between the cut parts. The internal opening was closed with a suture. Patients had a minimum follow-up of 6 months after last fat graft injection.

resultsTwenty-seven women underwent 48 procedures. The cause of fistula was obstetric (n = 9), abscess (n = 9), Crohn's disease (n = 7), radiation for anal cancer (n = 1) and endoscopic surgery after radiation for rectal cancer (n = 1). The mean amount of injected fat was 73 ml (SD ± 20 ml), and operating time was 63 min (SD ± 21 min). At median follow-up of 20 months (range 6-87 months) after the last injection, fistulas were healed in 21 women (77%), in 8 women after just one procedure. Healing was achieved in 6 of 7 women (86%) with Crohn's disease and in both women who had undergone radiation therapy. One woman developed an abscess and additional trans-sphincteric fistula 8 weeks after injection.

conclusionsFat graft injection for anovaginal fistulas is effective and safe.
