Abstract

An abdomino-pelvic perfusion and lavage apparatus is disclosed to which skin surrounding an incision formed through an abdominal wall of a patient can be attached and suspended. The apparatus includes a containment vessel impermeable to water and air, having a wall having a base, wherein the wall has an upper end with a perimeter which defines an upper opening, a lower end with a perimeter which defines a base opening, a cranial end with a perimeter edge which defines an opening, and a caudal end with a perimeter edge which defines an opening. The containment vessel can be carried by a table on which a patient is positioned. Scaffolding carried by the containment vessel supports and elevates the skin surrounding the incision made through the abdominal wall of the patient and thereby forms a well above, and extending into, an abdomino-pelvic cavity. A plurality of fluid ports communicate through the wall of the containment vessel. The cranial opening and the caudal opening can be sealed around the patient's torso. A base seal can seal the base of the containment vessel to the table. Perfusion fluid can be supplied from a reservoir to one of the fluid ports communicating through the wall of the containment vessel and delivered to the well and can be withdrawn from the well and returned to the reservoir. A removable cover can be sealed over the upper opening of the containment vessel. The cover can be removed for visual inspection and manual manipulation of the lavage fluid and the patient's viscera. An air evacuation system can be connected to the fluid port and can evacuate aerosols and gasses from within the containment vessel. A heater can be used to heat the perfusion fluid when carrying out hyperthermic perfusion. The apparatus can be left in place on a patient for up to 5-10 days particularly when using cell-cycle specific chemotherapy agents which require long-term contact with tissues in order to achieve their optimal effect. Similarly, the apparatus can be used for repeated access to the abdomino-pelvic space in patients with peritonitis or pancreatitis.
