[Staged resection in rectal carcinoma].

INTRODUCTION

The objectives of surgical treatment of rectal cancer are radical tumor excision, low morbidity and adequate functional outcome. The technique of total mesorectal excision (TME) has reduced the rate of local recurrences and led to an increase of ultra-low colorectal and coloanal anastomoses, which have a higher risk for anastomotic leakage.

METHODS

Advantages, disadvantages and consequences of staged resection for rectal cancer are discussed on the basis of international literature and our own results.

RESULTS

There are few stringent criteria for the use of diverting stomas. The decision for staged resection is often influenced by the personal experience of the surgeon.

CONCLUSIONS

The occurrence of anastomotic leaks cannot be prevented by diverting ostomies, but the usually irreversible consequences regarding survival and functional outcome can be minimized.
