The introduction of laparoscopy for hernia repair permits intra-abdominal observation of a hernia and contralateral persistent processus vaginalis (CPPV). The current study's aim was to investigate the diameter of opening of an inguinal hernia and CPPV in patients with unilateral inguinal hernia, and to evaluate their correlation with age.
From September 2012 to August 2017, 569 pediatric patients underwent laparoscopic repair of unilateral inguinal hernia. We retrospectively evaluated the size of the hernia and CPPV by measuring the diameter of opening. Pearson correlation analysis and linear-by-linear association were used in the statistical analysis.
The median age at operation was 32.4 months (range 0.2-219 months). CPPV was observed in 330 patients (58.0%), and its incidence was significantly higher in patients with left inguinal hernias than in those with right inguinal hernias (62.8 versus 54.0%, p < 0.001). The mean diameter of opening for the hernias was significantly larger than that for CPPV (11.2 ± 3.1 vs. 6.1 ± 2.5 mm, p < 0.001). The incidence of CPPV gradually decreased from 77.2% in infants to 46.6% in the oldest age group (≥ 6 years) (p trend < 0.001). The diameter of the opening of a hernia was not correlated with increasing age, and the diameter of the opening of a CPPV was not correlated with increasing age, as well.
The diameters of a hernia and CPPV were identified in the current study, and the diameter was not correlated with increasing age. The incidence of CPPV was more common in patients with left inguinal hernias than in those with right inguinal hernias, and it gradually decreased with increasing age.
腹腔镜用于疝修补术可对疝及对侧持续鞘突（CPPV）进行腹腔内观察。本研究旨在调查单侧腹股沟疝患者腹股沟疝及CPPV的开口直径，并评估其与年龄的相关性。
2012年9月至2017年8月，569例小儿患者接受了单侧腹股沟疝的腹腔镜修补术。我们通过测量开口直径对疝及CPPV的大小进行了回顾性评估。统计分析采用Pearson相关分析和线性-线性关联分析。
手术时的中位年龄为32.4个月（范围0.2 - 219个月）。330例患者（58.0%）观察到CPPV，左侧腹股沟疝患者中其发生率显著高于右侧腹股沟疝患者（62.8%对54.0%，p＜0.001）。疝的平均开口直径显著大于CPPV的平均开口直径（11.2±3.1对6.1±2.5mm，p＜0.001）。CPPV的发生率从婴儿期的77.2%逐渐降至最大年龄组（≥6岁）的46.6%（p趋势＜0.001）。疝开口直径与年龄增长无关，CPPV开口直径也与年龄增长无关。
本研究确定了疝及CPPV的直径，且该直径与年龄增长无关。CPPV在左侧腹股沟疝患者中比右侧腹股沟疝患者更常见，且随年龄增长逐渐降低。
