In vivo MRI visualization of parastomal mesh in a porcine model.

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
introductionAfter two-dimensional plane MRI-visible mesh implants could be successfully visualized in phantom and small animal model, the aim of the underlying study was to explore the feasibility of an MRI visualization of complex three-dimensional mesh geometry in close contact to the intestine. We therefore used a MR-visible three-dimensional intra-peritoneal stoma (IPST) mesh in a porcine model. MATERIALS AND
methodsLaparoscopic terminal sigmoid colostomy has been done with implantation of a prophylactic MRI-visible IPST mesh in two animals. MRI investigations were done after 1 week, 6 months and in case of clinical impairment. These findings were compared to endoscopy and makroscopical and histological investigation of the preparation.
resultsThe first animal has to be killed because of an ileus 4 weeks after operation. The second animal has to be killed after 7 weeks because of recurrent obstipation. In all cases MRI investigation could identify the IPST mesh and could clearly separate between mesh and intestine. MRI revealed a big bowl ileus due to a funnel dislocation in the first animal. In the second animal, MR diagnostic explored a functional stenosis because of a too small diameter of the central funnel in combination with sticky feces and distension of the terminal sigmoid before discharging into the funnel. Endoscopy, makroscopical and histological investigation of the preparation supported MRI findings.
conclusionAlthough complicate clinical course was a diagnostic challenge exploring 3D implants such as IPST, visualization of this new MRI-visible IPST mesh could be proved and turned out as an effective diagnostic possibility. Further studies are necessary to analyze long-time effects such as shrinkage, mesh migration and tissue integration using MRI scanning.
