Abstract:

BACKGROUND: Absorbable suture with good biocompatibility and mechanical strength has been extensively used in the clinic.
OBJECTIVE: To explore in vitro degradation of different absorbable sutures, to analyze the clinical superiority of absorbable sutures and the influential factors for its in vitro degradation.
METHODS: After retrieval of related literatures concerning degradation and application of absorbable suture material, we retrospectively analyzed relevant articles addressing influential factors for performance and degradation of absorbable suture materials, and comparison of clinical absorbable and nonabsorbable sutures, thereby providing theoretical evidence for clinical application.
RESULTS AND CONCLUSION: Absorbable sutures can be completely degraded and absorbed by the body, with no adverse reaction and no scars after wound healing. Absorbable sutures overcome the shortcomings of nonabsorbable sutures that cannot break down in the body. The absorption of its degradation products in vivo has two pathways: one is the phagocytosis of giant cells and phagocytes in the body, and the other is that the degradation products enter the body fluids and blood. For example, lactic acid is absorbed and excreted via the systemic circulation. There is a very complicated physiological environment in the human body, and various factors can affect material properties. In addition, the different kinds of materials have different degradation manners in vivo. Therefore, it is necessary to design, synthesize and process biodegradable polymer materials with special properties within a certain range to meet the clinical needs.
