[Application analysis of laparoscopic assisted microsurgical vasovasostomy in the treatment of vas deferens obstruction caused by inguinal herniorrhaphy].

[OBJECTIVE] To investigate the effiicacy of laparoscopic assisted microsurgical vasovasostomy in the treatment of vas deferens obstruction caused by inguinal herniorrhaphy.

[METHODS] Clinical data of patients undergoing surgical treatment for deferential obstruction after inguinal hernia repair in the andrology department of the First Affiliated Hospital of Zhengzhou University from 2018 to 2022 were retrospectively analyzed, and they were divided into two groups according to different surgical methods: double mirror combined group and microscope group. The basic clinical data, intraoperative conditions, postoperative effects and complications of the two groups were compared.

[RESULTS] There were 14 cases in the double mirror group and 34 cases in the microscope group. There was no significant difference in age and history of groin operation between the two groups (P>0.05). The average length of hospital stay in the two-lens group was less than that in the microscope group (5.07±0.26 days vs 7.09±1.86 days, P< 0.01), and the average operation time in the two-lens group was more than that in the microscope group (211.93±58.55min vs 162.26±40.70min, P<0.01). The postoperative recurrence rate (85.7% vs 73.5%, P > 0.05) was similar between the two groups. There was no significant difference in early postoperative complications (0% vs 2.9%, P > 0.05). Only 1 patient in the microscope group experienced fat liquefaction and recovered after intensive dressing change.

[CONCLUSION] Laparoscope-assisted microscopy provides natural fertility opportunities for patients with vas deferens obstruction after inguinal hernia repair, reduces the difficulty of surgery and the length of hospital stay, and is a safe and effective surgical method comparable to traditional surgical methods.
