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.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeAnocutaneous advancement flap is a surgical procedure for the treatment of chronic anal fissures. This study aimed to assess the results of anocutaneous advancement flap in a consecutive cohort of patients.

methodsThis is a retrospective, observational study. From 2000 to 2011, 481 patients had been operated for a single chronic anal fissure at the Maingau Clinic of the German Red Cross in Frankfurt am Main. The intention was to excise the fissure by fissurectomy (FIS) and then to cover the wound primarily with an anocutaneous advancement flap (AAF). The primary outcomes were resolution of symptoms and healing rates 1 month postoperatively. Secondary outcomes included incidences of early and late complications, postoperative incontinence, and recurrent fissure.

resultsAnocutaneous advancement flap was performed in 455 (94.6%). In 26 (5.4%) patients, AAF failed due to lacking skin and the wound left open after FIS. One month postoperatively, half of the patients with AAF were free of symptoms (53.2%) with complete wound healing (47.9%). The incidence of early complications within 1 month postoperatively was 0.9% after AAF. From 1 month to 5 years after operation anal abscesses and fistula occurred in 2.9%. Mild symptoms of anal incontinence were recorded in 0.2% and recurrent chronic anal fissure in 3.3% of patients. Subgroup analysis revealed improved wound healing 1 month postoperatively in patients with AAF compared to FIS.

conclusionAnocutaneous advancement flap is a very safe sphincter-sparing surgical option for CAF, provides a quicker cure than fissurectomy, and may be considered a good first-line surgical treatment option for chronic anal fissures if medical treatment failed.
