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 patients torso.

An abdomino-pelvic lavage apparatus adapted to be secured in a midline abdominal incision to form a well with the abdomino-pelvic cavity for lavaging the abdomino-pelvic cavity during surgery. The apparatus includes a cylindrical wall made of a transparent plastic material and having structure at its base end for securing the wall in place and effecting a water-tight seal with the edge of an abdominal incision. Ports through the wall around its circumference provide openings for the surgeon's hands so that the surgeon has free access to the abdomino-pelvic cavity for manipulation of intra-abdominal tissues, lavage fluid and inflow and outflow tubes for the lavage fluid. A transparent removable cover may be placed on the wall during chemotherapy treatment to contain fumes and prevent spillage, and to permit pressurization of the well and abdomino-pelvic cavity. Inflow tubes extend through the wall to admit lavage fluid and pressurized gas into the abdomino-pelvic cavity, and outflow tubes drain the lavage fluid from the cavity. Heat sensors, pH monitors, and a pressure gauge on the apparatus, and associated Geiger counters permit accurate monitoring and control of these parameters in the abdomino-pelvic cavity during the procedure.
