Drainage in gynecologic surgery.

Our predecessors' almost universal use of drains is gradually being replaced by a more scientific approach--selective use of more appropriate types of drains. Each application of drains must be evaluated in the context of other improvements in wound care and construction. Randomized, well-controlled studies are essential. Radical surgery is the strongest indication for the use of drains. There are few strong indications in benign gynecologic surgery.
