BACKGROUND
Duplication of vas deferens is a very rare congenital anomaly with only a few cases reported in the literature. Injury to vas deferens is a recognized complication during hernia surgery and the possibilities of injury may increase with lack of awareness of this anomaly.
CASE REPORT
A-31-year old gentleman with unilateral duplication of vas deferens that was diagnosed during right sided open hernia surgery is reported. The patient had undergone surgery for left inguinal hernia one year previously at the same center and no such anomaly was detected. During intra-operative examination of scrotum, the testes and epididymis were found to be normal. Patient had an uneventful recovery from hernia surgery.
CONCLUSION
Unilateral duplication of vas deferens is rare. The identification of this anomaly is essential in order to minimize the incidence of injury to vas during hernia surgery. This case reinforces the importance of routine identification of vas deferens and awareness about this anomaly during inguinal hernia surgery.
背景
输精管重复是一种非常罕见的先天性异常，文献中仅报道了少数病例。输精管损伤是疝手术中公认的并发症，而由于对这种异常缺乏认识，损伤的可能性可能会增加。
病例报告
本文报告了一名31岁男性，在右侧开放性疝手术中被诊断为单侧输精管重复。该患者一年前在同一中心接受了左侧腹股沟疝手术，当时未发现此类异常。术中检查阴囊时，发现睾丸和附睾正常。患者疝手术后恢复顺利。
结论
单侧输精管重复罕见。识别这种异常对于将疝手术中输精管损伤的发生率降至最低至关重要。该病例强化了在腹股沟疝手术中常规识别输精管以及认识这种异常的重要性。
