To compare and analyze the safety and effectiveness of T-shaped incision dissection and hernia sac dissection in the clinical application of laparoscopic transabdominal preperitoneal hernia repair (TAPP).

Collected clinical data of 127 male patients with unilateral inguinal hernia diagnosed and admitted to the 904th Hospital of the Joint Logistics Support Unit of the PLA from January 2017 to December 2019, 67 patients with T-shaped incision dissection and 60 patients with hernia sac dissection; a retrospective analysis of the clinical data of the two groups of patients, comparing the operation and hernia sac treatment time, intraoperative blood loss, spermatic cord injury, postoperative pain score, postoperative seroma and long-term recurrence etc.

In the group of T-shaped incision dissection, operation time, time for hernia sac treatment, intraoperative blood loss, intraoperative spermatic cord blood vessel and vas deferens injury, the incidence of control and postoperative seroma were better than that in the hernia sac dissection group, and the difference was statistically significant (P<0.05). Intraoperative abdominal wall vascular injury, postoperative incision infection, urinary retention and scrotal effusion were no statistically significant difference (P>0.05); there was no significant difference in the early postoperative pain score and long-term chronic pain incidence between the two groups (P>0.05); there was no statistically significant difference in postoperative recurrence (P>0.05).

The T-shaped incision dissection technique can significantly shorten the operation time, reduce intraoperative bleeding, and reduce the accidental injury of the spermatic cord during TAPP surgery, thereby reducing the difficulty of surgery, and the early and long-term complications control is not worse than the hernia sac striped group. It was a safe and effective surgical treatment.
