Catheters, Peritoneal, Percutaneous Drainage, Multiple Lumen

Definition : Percutaneous drainage peritoneal catheters which include a second-sump lumen that permits ingress of air to favorably allow the use of positive suction and prevents adherence of the side holes to the wall of the abscess; most of them have additional lumens (e.g., for simultaneous irrigation). The main lumen usually consists of a large bore tube (12 to 14 Fr) to facilitate complete aspiration of the cavity content and large side-hole apertures that assure ready flow of thick purulent material. Multiple-lumen peritoneal catheters are mostly used for drainage of clinically evident pus when the estimate volume of the collection is large (e.g., more than 100 ml).
