[Difficulties in the analysis of peritoneographic images]

Peritoneography was performed in 122 patients clinically suspected of hernia without definite palpation findings. 108 cases could be assessed without any doubt (in 40 patients proof of hernia and in 68 patients definite exclusion of hernia). In 14 cases (= 11.5%) the images were difficult to classify. These cases and the variations of normal x-ray anatomy are described.
