The reason for the right side predominance of inguinal hernias was studied. The case histories of 469 patients who had undergone inguinal hernia operations were analysed. 116 of the hernias were bilateral whereas 207 were right and 146 left sided, the difference being significant at the level p less than 0.05. More right than left hernias were found in every subgroup studied (children, women, men; direct, indirect, older people; with suspected increased intra-abdominal pressure). Neither of the two hypotheses envisaged for this side difference could be confirmed. These were a structural side difference in the inguinal canals, and a neuromusculature damaging abdominal incision. It is postulated that a physiological asymmetricity of the body musculature could be an explanation rather than any anatomical reason.
对腹股沟疝右侧优势的原因进行了研究。分析了469例接受腹股沟疝手术患者的病历。其中116例为双侧疝，207例为右侧疝，146例为左侧疝，差异在p<0.05水平具有统计学意义。在研究的每个亚组（儿童、女性、男性；直疝、斜疝、老年人；怀疑腹内压升高者）中，右侧疝均多于左侧疝。针对这种左右侧差异所设想的两种假说均未得到证实。这两种假说是腹股沟管的结构侧差异以及损伤神经肌肉的腹部切口。据推测，身体肌肉组织的生理不对称性可能是一种解释，而非任何解剖学原因。
