Abstract:
【Objective】 To introduce a modified microdot two-layer microsurgical vasovasostomy (MVV) and to analyze its effectiveness in patients with vas deferens obstruction caused by inguinal herniorrhaphy. 【Methods】 Clinical data of patients treated during Mar.2015 and Oct.2020 were retrospectively analyzed. According to different surgical methods, the patients were divided into the modified group and traditional group. The general data, intraoperative conditions, efficacies and complications of the two groups were compared. 【Results】 There were 59 cases in the modified group, 54(91.5%) of whom were successfully followed up, and 41 cases in the traditional group, 38(92.7%) of whom were successfully followed up. There were no significant differences in age, inguinal herniorrhaphy history, and unilateral/bilateral ratio between the two groups (P>0.05). The average operation time for unilateral lesions in the modified group was shorter than that in the traditional group [(89.44±24.86) vs. (112.04±43.40) min, P=0.032]. The postoperative patency rate (83.3% vs.73.7%, P>0.05) and natural pregnancy rate (33.3% vs.28.9%, P>0.05) of the modified group and traditional group were comparable. Incision fat liquefaction occurred in 2 cases (3.70%) in the modified group and in 1 case (2.63%) in the traditional group (P>0.05). 【Conclusion】 The modified microdot two-layer MVV is a safe surgical method with comparable effectiveness as the traditional approach. By adjusting the position of the marking points and the order of suturing, it helps the management of sutures, reduces the difficulty of vasovasostomy, shortens operation time, and can be applied to repair vas deferens obstruction caused by inguinal herniorrhaphy.
