[Effect of proctocolectomy on fluid balance--comparison of conventional ileostomy, ileorectal anastomosis and ileoanal pouch operation].
Total colectomy for ulcerative colitis (UC) and familiar adenomatous polyposis coli (FAP) is mainly performed as an ileoanal Pouch procedure (IAP). Alternatives are ileorectal anastomosis (IRA) and conventional proctocolectomy with Brooke ileostomy (CPS). The different surgical techniques may influence the excretion of water and electrolytes in stool and urine and may lead to a higher risk for urolithiasis. We investigated patients (12 IAP, 12 IRA and 8 CPS) several years after surgery and compared them to twelve normal controls. Total fecal and urinary output was collected at two consecutive days. Volume and electrolytes were determined in stool and urine. The risk for urinary stone formation was calculated by nomograms. Fecal volume and sodium (Na+) excretion was increased in all therapy groups compared to controls. IAP and IRA had significant less stool volume and Na+ excretion compared to CPS. Augmented fecal Na+ excretion was compensated by reduction of renal output after colectomy compared to controls. There were no significant differences in the daily urine volume between any groups. There was no urolithiasis in any groups. The nomograms showed a risk for all groups and controls to develop urinary stones.
