Herniography frequently reveals clinically undetected groin hernia. Thereby herniography contributes to the clinical work-up in patients with obscure groin pain. However, the distinction between clinically important and unimportant abnormalities within the lateral inguinal fossa can be difficult. This study was therefore designed in order to elucidate the herniographic appearance of the lateral inguinal fossa in patients with obscure groin pain. Herniographic findings were compared with laterality of the patients' symptoms. The lateral umbilical fold was visible in only 47 per cent of the groins. A triangular shaped outpouching from the lateral inguinal fossa and a patent processus vaginalis were found with equal frequency on the left and right side. They were five times as frequent in men as in women. Their presence did not correlate with laterality of the patients' symptoms. Indirect hernias were almost twice as common on the symptomatic side as compared with the asymptomatic side. On the left side they were found twice as often in men as in women while there was no significant sex difference on the right side. Our results show that neither a patent processus vaginalis nor a triangular outpouching from the lateral inguinal fossa correlate with the laterality of the patients' symptoms while true indirect hernias do.
疝造影术常常能发现临床上未被检测出的腹股沟疝。因此，疝造影术有助于对腹股沟疼痛不明确的患者进行临床检查。然而，区分腹股沟外侧窝内临床上重要和不重要的异常可能具有一定难度。因此，本研究旨在阐明腹股沟疼痛不明确的患者腹股沟外侧窝的疝造影表现。将疝造影结果与患者症状的侧别进行比较。仅47%的腹股沟可见脐外侧襞。在腹股沟外侧窝发现的三角形突出和鞘状突未闭在左侧和右侧出现的频率相同。它们在男性中的出现频率是女性的五倍。它们的存在与患者症状的侧别无关。与无症状侧相比，间接疝在有症状侧的出现几率几乎是其两倍。在左侧，男性发现间接疝的频率是女性的两倍，而在右侧则没有明显的性别差异。我们的结果表明，鞘状突未闭和腹股沟外侧窝的三角形突出均与患者症状的侧别无关，而真正的间接疝则与之相关。
