[Colostomy control using an original occluding device. A clinico-experimental study].

Abstract

After having examined different methods as to continence colostomy, the authors introduce their own control system for the stoma. The study was carried out on 6 colostomized patients. Preliminary, the intraluminal pressure in closed colostomy was recorded. Pressure waves, largely varying from patient to patient, were obtained as to frequency of waves and pressure values. The same variations were observed during meals waking and sleeping. Sometimes the patients suffered from serious disorder, but in most cases they did not feel pain. A catheter, provided with an inflatable balloon for closing the stoma, formed the system tested. It was also provided with a second intraluminal low-pressure inflated balloon, connected with an external compensating chamber. As a result of the system the pressure dropped down to about 1/6 compared with the reference values observed under the same conditions. In addition, the continence was complete and the patient did not suffer from any disorder in non-stop recordings up to 24 hours. We believe that the system may be useful for colostomized patients if carefully carried out.
