[Gas gangrene: an extreme surgico-medical rather than medico-surgical emergency].

A diabetic woman developed spontaneous gas gangrene of upper limb extending into trunk and due to clostridium septicum. Recovery was obtained after major surgery involving disarticulation of upper limb and excision of soft tissues of left hemithorax, and a difficult intensive care programme (hyperbaric oxygen therapy, assisted ventilation). The presence of this gas gangrene revealed a bipolar colon cancer treated in parallel. The conventional therapeutic hierarchy is discussed: surgery should be carried out as an extreme emergency and should not be delayed to allow transfer to a center equipped with a hyperbaric oxygen therapy apparatus.
