[The rehabilitation of compensatory changes after right side hemicolectomy].
Macro- and microscopic changes in the anastomosis region, motor-emptying function of the small bowel, and immunological changes also, were experimentally investigated after the right-sided hemicolectomy conduction. Compensatory dilation of colon, transversum for the absorbtion square increase with simultaneous wall thinning was revealed. The stump may reduce or dilate. Lymphoid follicles appear in the small bowel submucosa. The accelerated emptying of the small bowel contents become slower after its circular division up to submucosa on 20 and 40 cm distance from anastomosis. General T-lymphocytes quantity, T-helpers/T-suppressors ratio reduces abruptly on the third day with gradual increase on the 5th, 7th and 30th day. At the same time the IgM, IgG, IgA levels, the index of spontaneous and stimulated NBT-test rises on the third day, stabilizing slowly before the 30th day.
