[Technique and results of the colon conduit, continent by means of a new magnetic stoma seal. An animal experiment study. Enterocystoplasty as model of continent urinary diversion. Review and comparison of the results of colocystoplasty, coloprostatoplasty and colourethroplasty (authors transl)].
On the basis of satisfactory results with a new magnetic stoma seal in colostomy patients, this seal, consisting of a magnetic ring and cap, was used in an experimental study to convert the colonic conduit into a continent reservoir. The aim of the study, involving 16 dogs, was to find a method of ring implantation that would avoid infection of the ring and yield complete continence in a higher percentage than had been achieved so far in patients. Complete continence was obtained in all animals but there was a 75% incidence of immediate and delayed infection of the magnetic ring when the ring was inserted transcutaneously. In contrast, all rings were well accepted by the tissue when the procedure was staged with the ring being implanted transperitoneally several weeks prior to fashioning of the conduit. The general problems arising from the colonic conduit when used as continent reservoir are known from the results of colocystoplasty, coloprostatoplasty and colourethroplasty, which are reviewed and compared with our observations. Residual urine was low due to an ideal energy-balance pattern. Coloureteric reflux was successfully prevented in all cases operated on by a long-tunnel modification of the Leadbetter-Clarke technique. Hyperchloremic acidosis and renal function deterioration were not observed. All conduits were infected.
