Combined Penrose and silicone drains provide excellent drainage.

We designed an effective combination drainage, using available silicone and Penrose drains, the latter placed within the former. Occlusion at the tip by fibrin materials never occurs in clinical application. If complications, such as leakage and abscess have occurred, this drain is extremely effective to ensure drainage and suction or irrigation, or both, as the Penrose drain can be replaced with sump tube drain. This simple hybrid for double lumen drain has proved to be both efficient and safe.
