A novel magnetic device to prevent fecal incontinence (preliminary study).

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.
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
BACKGROUND AND
aimsIn this research we propose an original magnetic device to strengthen the hypo-atonic anal sphincter and prevent fecal incontinence.
methodsThe device consists in a couple of small magnetic plaques to be surgically inserted in the wall of the anal canal between the external and internal anal sphincters with the opposite polarities face to face, so that, attracting themselves, close the anal lumen. Three couples of magnets made of materials of different magnetic force (neodymium>ferrite>plastoferrite) were evaluated in each of three swine anatomical preparations by measuring the endoanal pressure with a manometric catheter, both before and after magnet implantation. The mean pressures obtained before and after magnet insertion were statistically compared with Student t test.
resultsThe endoanal pressure after the insertion of neodymium magnets was 79.7+/-13.1 (mean+/-SD), after ferrite magnets was 42.1+/-5.6 mmHg and after plastoferrite magnets was 21.6+/-4.6 mmHg, all of them significantly higher than the pressure recorded in basal conditions (1.72+/-0.71 mmHg).
conclusionThis research demonstrated that the implantation of a couple of magnets in the wall of the anal canal is able to create a high pressure zone of a value sufficient to prevent fecal incontinence and that the strength of this "dynamic closure" can be modulated by using magnets of various attraction force, so allowing a "tailored correction" of the anal sphincter hypotension.
