[Intraperitoneal chemo-hyperthermia with "overflow" open abdomen]

The authors report an original procedure of open-abdomen intraperitoneal chemo-hyperthermia. The skin edges are watertightly stapled with a soft "abdominal cavity expander", supported by a Thompson self-retaining retractor positioned over the abdomen. So, the level of the liquid can be widely raised above the level of the skin edges. The anterior wall peritoneum, the wall edges are constantly exposed to the liquid. Large amplitude movements become possible: introduction into the abdomen of two forearms, even two arms, does not induce loss of any liquid. The small bowel, the stomach can be partially exteriorized. It becomes very easy to expose all the peritoneal spaces, to maintain an homogeneous hyperthermia within the abdomen, while using only one inflow drain, and one outflow drain.
