Abstract
A method is described for using percutaneous access to a patient to remove an object from a cavity within the patient. The method includes inserting a suction tube into a port created by a percutaneous cut. An endoscope is also advanced into the cavity, however the endoscope passes through a patient lumen rather than through the port. Using a working channel within the endoscope, fluid is irrigated through the cavity. Additionally, a negative pressure is applied to the suction tube, such that the combination of fluid irrigation and negative pressure assist in removing the object from the cavity through the suction tube.
