Methods

A total of 204 male patients with primary obtrinal inguinal hernia（inner ring ≥3 cm or scrotal hernia）were prospectively selected from January 2020 to January 2022，all of whom received TAPP treatment. Random number table method was used to divide 102 cases into two groups. The study group had the distal hernia sac sutured and fixed in the joint tendon after transection，while the control group had the distal hernia sac isolated and free in the scrotum after dissection. SPSS 26.0 statistical software was used for analysis. Such as seroma and complications were expressed as［n（%）］. χ² test was performed for inter-group comparison，and Rank Sum test was performed for rank count data. Measurement data such as perioperative indicators were represented with（

±s），and t test was used for comparison between groups. P<0.05 was considered statistically significant. Results There was no significant difference in operation time，intraoperative blood loss，postoperative hospital stay，operation cost and hernia recurrence rate between the two groups（P>0.05）. There were significant differences in the incidence of postoperative inguinal seroma between the study group and the control group（8.8% vs. 18.6%）and the amount of fluid extracted（20.62.4 vs. 42.75.3）（χ²/t=2.107，38.363，P=0.035，0.000）. The overall incidence of complications between the two groups（5.9% vs. 14.7%）was statistically significant（χ²=4.300，P=0.038）. Conclusion The distal hernia sac is sutured and fixed to the joint tendon after transection of the hernia sac in TAPP，which can reduce the incidence and severity of postoperative seroma，reduce postoperative complications，and have high surgical safety，which is worthy of clinical promotion.
