Abstract:

Objective

To study the clinical efficacy and safety of laparoscopic transabdominal preperitoneal hernioplasty for recurrent inguinal hernia.

Methods

PubMed, China Biomedical Literature Service System, China HowNet and Wanfang database were retrieved by computer. The clinical efficacy and safety of laparoscopic transabdominal preperitoneal hernioplasty for recurrent inguinal hernia from database building to June 2019 were collected and strictly reviewed by two researchers according to the inclusion/exclusion criteria. The two researchers independently completed literature screening, related data extraction and quality evaluation. Data were analyzed by RevMan 5.3 statistical software.

Results

10 studies involving 2583 patients were included. The results of meta-analysis showed that: (1) There was no significant difference in operation time between the experimental group and the control group (P>0.05); Subgroup analysis results: in tension-free repair group (including Lichtenstein) and TEP group, the operation time of the experimental group was not significantly different from that of the control group (P>0.05), while in open posterior preperitoneal approach group, the operation time of the experimental group was significantly different from that of the control group (P<0.05). (2) There was no significant difference in anal exhaust time between the experimental group and the control group (P>0.05). (3) The length of hospital stay of the experimental group was significantly different from that of the control group (P>0.05); Subgroup analysis results: the length of hospital stay of the experimental group was not significantly different from that of the control group in the tension-free repair group (P>0.05), while the length of hospital stay of the experimental group was significantly different from that of the control group in the TEP group and the open posterior preperitoneal approach operation group (P<0.05). (4) There was significant difference in postoperative complications between the experimental group and the control group (P<0.05); Subgroup analysis results: in tension-free repair group and open posterior preperitoneal approach operation group, the postoperative complications of the experimental group were significantly different from those of the control group (P<0.05), while in TEP group, the postoperative complications of the experimental group were not significantly different from those of the control group (P>0.05). (5) There was no significant difference in the recurrence rate between the experimental group and the control group (P<0.05); Subgroup analysis results: in the tension-free repair group, the postoperative recurrence rate of the experimental group was significantly higher than that of the control group (P<0.05), while in the TEP group and the open posterior preperitoneal approach operation group, the hospital stay of the experimental group was not significantly different from that of the control group (P>0.05).

Conclusion

Laparoscopic transabdominal preperitoneal herniorrhaphy has great advantages in the treatment of recurrent inguinal hernia with less postoperative complications and low recurrence rate, and it is worthy of clinical application.
