Patients with genetic defects of protein C and S, and factor V Leiden defect for examples have the perioperative risk of hypercoagulability. The

Therefore their efficiency depends on the position of the patient and the volume and site of the collection. If a fistulous track is necessary to provide a long period of drainage, such as bilary drainage after exploration of the common bile duct latex drains are preferable as fibrosis is stimulated.
