To investigate the efficacy and safety of laparoscopic modified total extraperitoneal hernia repair (TEP) and laparoscopic transabdominal preperitoneal hernia repair (TAPP) in the treatment of inguinal hernia.

55 patients with inguinal hernia treated by modified laparoscopic TEP in our hospital from January 2017 to January 2019 were retrospectively selected as the modified TEP group, and 55 patients with inguinal hernia treated by TAPP at the same time were collected as the TAPP group. The operative indexes, hospitalization indexes, intraoperative conditions and complications were observed and compared between the two groups.

The operation time, recovery time and hospitalization time of patients in the modified TEP group were shorter than those in the TAPP group, and the intraoperative blood loss, postoperative VAS score and hospitalization expenses were lower than those in the TAPP group (P<0.05). There was no significant difference in the incidence of massive hemorrhage, peritoneum, hernial sac, intestinal tract injury, nerve injury, blood vessel injury and free inferior epigastric vessel between the two groups (P>0.05). There was no statistical difference in the incidence of short-term and long-term complications between the two groups (P>0.05).

TAPP and modified TEP have good safety in the treatment of inguinal hernia. Compared with TAPP, modified TEP can shorten the operation time, reduce the amount of bleeding, reduce postoperative pain, promote postoperative recovery of inguinal hernia patients, and reduce hospitalization expenses. However, it has higher requirements on the operator and should be selected according to the actual situation in clinic.
