To investigate the effect of laparoscopic trans-abdominal preperitoneal hernia repair(TAPP) repair on postoperative recovery, coagulation function and prognostic recurrence rate of patients with inguinal hernia.

A total of 116 patients with inguinal hernia in Handan Central Hospital from February 2018 to April 2020 were selected, and they were divided into TAPP group (n=58) and traditional group (n=58) according to the treatment method. The TAPP group received TAPP repair, and the traditional group received traditional tension-free hernia repair. To compare the levels of coagulation function indexes [activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB)] before operation, 1 days after operation, and 3 days after operation in the two groups. The incidence of postoperative complications, recurrence rate and scars aesthetics at 6 months after operation, and the sexual function indexes (testicular volume and maximum blood flow velocity of testis) before operation, 3 months and 6 months after operation were also calculated.

Although the operation time of the TAPP group was longer than that of the traditional group, the postoperative time of getting out of bed and hospital stay were shorter than those of the traditional group, and the intraoperative blood loss was lower than that of the traditional group (P<0.05). The serum APTT and PT levels of the two groups at 1 d and 3 d after operation were shorter than those before operation, and the FIB level was higher than before operation (P<0.05), but there was no significant difference between the groups (P>0.05). The incidence of postoperative complications in the TAPP group was lower than that in the traditional group (P<0.05). The scars aesthetics in the TAPP group at 6 months after surgery was better than that in the traditional group (P<0.05), and the recurrence rate in TAPP group at 6 months after surgery was lower (P<0.05). The testicular volume and maximum blood flow velocity at 3 and 6 months after surgery in both groups were lower than those before surgery, but those in TAPP group were higher than those in traditional group (P<0.05).

TAPP in the treatment of inguinal hernia patients has the advantages of less trauma, less bleeding, quick postoperative recovery, fewer complications, better scar aesthetics and low recurrence rate. It can improve the appearance of scar and reduce the impact on the sexual function of male patients. However, the operation time is prolonged, and attention should be paid to the effect of pneumoperitoneum on the coagulation function during the operation.
