Clinical Study on the Application of Biological Mesh and Synthetic Mesh in Laparoscopic Inguinal Hernia Repair

Objective To study the effectiveness and safety of biological mesh in laparoscopic inguinal hernia repair. Methods Through a retrospective study, 200 patients with inguinal hernia admitted to the Second Affiliated Hospital of Xi'an Jiaotong University from March 2019 to March 2022 were divided into two groups. The group repaired with acellular matrix biological mesh was set as the experimental group (100 cases), and the group repaired with polypropylene mesh was set as the control group (100 cases). The surgical method was laparoscopic transabdominal preperitoneal inguinal hernia repair (TAPP). The operation time, intraoperative blood loss, postoperative hospital stay of the patients in the two groups were mainly compared, as well as the recurrence rate of hernia, the infection rate of the incision and the mesh, seroma, foreign body sensation, chronic pain and other conditions. Results There were no significant differences in general data, operation time, intraoperative blood loss, postoperative hospital stay and other aspects between the two groups of patients ( P > 0.05). There were no significant differences in the recurrence rate of hernia, the infection rate of the incision and the mesh, the incidence of seroma, the incidence of chronic pain and other aspects between the two groups of patients ( P > 0.05). The incidence of foreign body sensation after operation in the control group was higher than that in the experimental group, and the difference was statistically significant ( P < 0.05). Conclusion The acellular matrix biological mesh is safe and effective in the treatment of inguinal hernia, and can reduce the incidence of postoperative foreign body sensation at the same time, providing a new choice for laparoscopic inguinal hernia repair.
