J. Kirchner et al., SPONTANEOUS PNEUMOPERITONEUM AND RETROPNE UMOPERITONEUM WITHOUT ALIMENTARY-TRACT PERFORATION, Zentralblatt fur Chirurgie, 121(10), 1996, pp. 861-865
Asymptomatic radiologically recognised pneumoperitoneum still remains
a diagnostic and therapeutic dilemma, because free intraperitoneal air
is not necessarily caused by alimentary tract perforation. We present
two cases of nonsurgical pneumoperitoneum (caused by pneumomediastinu
m and pneumatosis intestinalis cystoides) and their typical radiologic
findings. Other causes of pneumoperitoneum that do not necessitate la
parotomy so as cited in the radiologic and surgical literature are dis
cussed.
