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

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.

[Peritoneal oxygenation-dialysis as a temporary treatment of intestinal infarction].

The interval preceding the growth of irreversible lesions in an abdominal apoplexy is variable (3-48 hours). It may be used to improve the ischaemic viscus oxygenation, also compensating possible metabolic imbalances. 16 rabbits were used for research, in which apoplexy by the ligature of the arteria mesenterica superior was induced. Dialysis-oxygenation peritoneal treatment was carried out for 8 rabbits, the results of which were evaluated on the basis of the intestine macroscopic morphologic aspect; on the basis of the hematic phosphates values and in enteral biopsy. The oxygenation-dialysis produced a rapid improvement in enteral hue and in enteral motility, an important increase of PO2 and a reduction of hematic phosphates compared with the control group. Histologic examination did not show any significant variation. The attempt to increase general oxygenation by supplying PO2 via the peritoneum, was partly successful (10-15%). The aim of oxygenation the ischaemic enteral zone was successful. This due to elimination of CO2 and toxic products using dialysis. This simple method seems to be effective but further tests on swine would be necessary for clinical applications.
