Abstract: Objective To compare the safety and feasibility of laparoscopic total extraperitoneal herniorrhaphy (TEP) and laparoscopic transabdominal preperitoneal prosthesis(TAPP) in the treatment of inguinal hernia.Methods This study adopts retrospective cohort study method.The clinical data of 107 cases of inguinal hernia treated by laparoscopic inguinal hernia repair in Minimally Invasive Surgery,Hernia and Abdominal Surgery of Xinjiang Uygur Autonomous Region People's Hospital from January 2014 to May 2024 were collected.According to the surgical methods, they were divided into two groups: 38 cases in the TEP group and 69 cases in the TAPP group.Compare and analyze the differences between TEP group and TAPP group in basic situation,operation,postoperative recovery,operation cost,postoperative inflammation index,liver and kidney function evaluation index.Results The time to start getting out of bed after surgery in the TEP group and the TAPP group was (14.55±1.95) h and (16.12±3.11) h, respectively (P=0.006). The recovery times of gastrointestinal function were (22.11±4.94) h and (24.61±4.88) h respectively (P=0.013). There was a statistically significant difference between the two groups (P<0.05).There was no significant difference in postoperative inflammation,liver and kidney function,postoperative complications and recurrence (P>0.05).Conclusion Both TEP and TAPP are safe and feasible in the treatment of inguinal hernia.After TEP,the time to get out of bed was shorter and the intestinal function recovered faster.
