[Changes in colitis surgery. II: Corrective interventions and conversion operations].

Over a period of 9 years in 48 patients already operated on for ulcerative colitis secondary surgical interventions had to be planned. 25 patients had an ileostomy (IS), 10 a Kock-pouch (KP), 11 an ileoanal pouch (IAP) and 2 an ileorectal anastomosis (IRA). Whereas in 4 patients only the subjective wish for another procedure with better quality of life predominated, in 44 patients (91.7%) also objective, sometimes multiple indications for reoperation existed. In 37 patients main indications were complications or dysfunctions of the preexisting procedures, combined with the need for further resection of the colitis in 6 of them. Resection of the residual colitis was the main indication in the remaining 7 patients. The aim of the reoperation in all patients was both complete elimination of the eventually persisting colitis and restoration of quality of life in the best way wished or possible. Our of 25 IS 3 remained, 3 were reconstructed, 17 were converted to KP and 2 to IAP. Out of 10 KP one remained and in 9 corrective surgery of the nipple valve was performed. Out of 11 IAP 2 had to be resected with construction of IS, 5 were converted to KP and 4 were corrected. Two IRA were converted to IAP. The rate of early complications was 8.3% (n = 4), lethality was zero. Late complications occurred in 13 cases (27.1%) and were associated ten times with KP. Complications of KP decreased with time to zero due to technical modifications. They could always be corrected restoring function. Since only one KP had to be resected due to severe pouchitis, KP was an important secondary procedure for 31 out of 48 patients also in the long-term course ensuring both complete elimination of colitis and good quality of life owing to voluntary fecal control.
