Abstract:

OBJECTIVE: Absorbable collagen suture has been reported to improve the healing effect for patients with type I and II surgical incisions. However, these studies are single-center small-sample trials, and the results are not clear. This study investigated the efficacy of absorbable collagen suture for type I and II surgical incisions.

METHODS: Databases of PubMed, Web of Science, Cochrane Library, CNKI, Wanfang,and VIP were searched to retrieve the randomized controlled trials concerning the effects of absorbable collagen suture. The modified Jadad scale was used to evaluate the quality of the included research literature. The main outcome indicators were wound healing grades, wound leveling, and wound healing time. The secondary indicators were wound pain, incisional red swelling, and wound bleeding. Meta-analysis was conducted using Stata 16.0 software.

RESULTS: (1) Eleven articles were included, and the median Jadad score was 3.0. There were 1 720 patients, including 887 patients in the trial group and 833 patients in the control group. (2) Meta-analysis results revealed that compared with the control group, in the trial group, incision healing level was improved (RR=1.44, 95%CI:1.02-1.86, P=0.00), and incision flatness was improved (RR=1.11, 95%CI:0.70-1.52, P=0.002); incision healing time was significantly reduced (WMD=-7.44, 95%CI:-8.09 to -6.79, P=0.00); incision pain was significantly reduced (RR=1.95, 95%CI:1.44-2.46, P=0.00); incision bleeding was significantly reduced (RR=-2.63, 95%CI:-4.65 to -0.61, P=0.01); incisional swelling was significantly reduced (RR=-1.00, 95%CI:-1.78 to-0.22, P=0.01).
CONCLUSION: The efficacy of absorbable collagen thread for type I and II surgical incisions was better than that of the silk thread and ordinary absorbable suture.
