Abstract

The function of the intestinal microflora was studied in patients with ulcerative colitis before and after colectomy. The following six microflora-associated characteristics (MACs) were investigated: formation of coprostanol and urobilinogen; degradation of mucin, water-soluble protein, and beta-aspartylglycine; and presence of faecal tryptic activity. In 12 unoperated patients without sulphasalazine as maintenance therapy the six MACs were similar to those in normal subjects. In 12 unoperated patients receiving sulphasalazine the formation of coprostanol and urobilinogen was significantly lower (p<0.01 and p< 0.001, respectively) and the level of faecal tryptic activity was significantly higher (p < 0.01) than in normal subjects. The functional capacity of the microflora in operated patients treated by colectomy combined with one of four surgical procedures (ileorectal anastomosis, ileoanal anastomosis with pelvic pouch, Kock's continent ileostomy, or conventional ileostomy) was disturbed with regard to all six MACs. The disturbance was most pronounced in patients with conventional ileostomy.
