Objective  To evaluate the clinical effectiveness and safety of different mesh fixation techniques in laparoscopic trans-abdominal preperitoneal hernia repair (TAPP) by using network meta-analysis. Methods  CNKI, WanFang Data, VIP, CBM, the Cochrane Library, PubMed, Embase, and Web of Science databases were retrieved to collect randomized controlled trials (RCTs) studies comparing different fixation methods of patches in laparoscopic TAPP. The retrieval time limit was from the establishment of the database to March 1, 2022. After two researchers independently screened the literatures, extracted the data, and evaluated the bias risk, Bayesian network meta-analysis was conducted by using R4.1.2 software. Results  Twenty-nine RCTs were included, including 4 095 patients. The results of network meta-analysis showed that the risk of chronic postoperative inguinal pain was higher in staples fixation than that of no fixation [OR=0.06, 95%CI (0.01, 0.26), P<0.001], glue fixation [OR=0.21, 95%CI (0.04, 0.53), P=0.001] and self-gripping mesh [OR=0.09, 95%CI (0.01, 0.52), P=0.009], the incidence of chronic postoperative inguinal pain with suture fixation was higher than that with no fixation [OR=0.10, 95%CI (0.01, 0.70), P= 0.020]. Postoperative visual analogue scale of staples fixation was higher than those of no fixation [MD=–0.90, 95%CI (–1.49, –0.33), P=0.002] and glue fixation [MD=–0.92, 95%CI (–1.35, –0.49), P<0.001], the postoperative visual analogue scale with suture fixation was higher than those of no fixation [MD=–0.83, 95%CI (–1.61, –0.08), P=0.030] and glue fixation [MD=–0.85, 95%CI (–1.56, –0.13), P=0.020]. There was no significant difference in the incidence of seroma and hematoma, hospital stay and hernia recurrence among different fixation methods. Conclusions  The network meta-analysis shows that medical glue and self-gripping mesh have certain advantages in reducing chronic pain after surgery, which may be the better patch fixation method in TAPP. The non fixation mesh will not increase the risk of postoperative recurrence, and can be used in clinical practice. This conclusion needs to be further verified by large sample, long-term follow-up and high-quality RCTs.
