title: [Pseudocontinent colostomy - a manometric study].
abstract: The intraluminal pressure in terminal segment of colon has been studied at 42 patients undergone an exterpation of rectum and taken out pseudocontinent colostomy onto a front part of the abdomen. Schmidt's pattern smooth muscle muff, modified in the Clinic Surgery and Coloproctology at MU--Varna, has been transplanted around the colon, taken out as continent colostomy. The intraluminal pressure in the terminal segment of colon has been identified with an index of resistance on the side the smooth muscle muff against the spontaneous evacuation of the colon content. The pressure has been registrated at rest and after the mechanical dillatation of muscle muff. The pressure at the check group of 20 patients with taken out continent colostomy has been investigated manometrically. The basal intraluminal pressure at the patients with a transplanted smooth muscle muff has been 30 +/- 2.9 mmHg at the end of the first postoperative month, as it has been sustained permanent (29.7 +/- 3.0 mmHg) up to the second postoperative jear (0.001). The pressure has been increased up to the mean value of 42 +/- 2.5 mmHg, as it has been sustained at this level for a period of 120 sec. The basal intraluminal pressure at the patients with transplanted smooth muscle muff has been more then four times higher in comparison with the pressure in c. sigmoideum, which has been a prerequisite for stopping of the spontaneous evacuation. A conclusion has been done that the index of resistance in the terminal segment of colon has been depended on a functional potential of the smooth muscle muff directly. The transplanted muff has been an anatomic structure manifested a functional activity in terms of isolation.
