Abstract
We report the indications, technique, and results of conversion of the ileoanal pouch to the Kock's pouch in five patients. The indication was functional disturbance that could not be corrected by operation. Aim of the conversion operation was re-establishment of fecal control and complete preservation of existing ileal surface. The ileal pouch was used again, and in one case an augmentation was made. The continence valve was made three times from the afferent loop and in two cases from a higher ileal segment. Following conversion, function was excellent in three patients with ulcerative colitis and in one patient with familial adenomatous polyposis. One woman who underwent proctocolectomy for slow-transit constipation needed a Brooke ileostomy for continuous abdominal distention pain. We conclude that conversion to a continent ileostomy is a rewarding method of safely eliminating dysfunction of the ileoanal pouch that cannot be corrected by operation. Presumption is, however, that the surgeon is familiar with both methods and that the primary disease is suitable for pouch surgery.
