[A personal case of spontaneous pneumoperitoneum and review of the literature].

A personal case of spontaneous pneumoperitoneum is reported and the nosographic importance of this form is reviewed. It is showed that primary forms, as opposed to those secondary to visceral perforation, always display a benign outcome. In some clearly-defined situations, therefore, a wait-and-see policy may be adopted, provided continuous surveillance of the position is assured.
