Surgical wound closure is a critical aspect of veterinary medicine, and the selection of the appropriate suture material significantly influences healing outcomes, complication rates, and long-term tissue stability. Understanding the distinctions between absorbable vs non absorbable sutures is essential for veterinarians who manage diverse tissue types, from muscle and subcutaneous tissue to fascia, tendon, and even vascular prosthesis applications.
The choice of surgical suture materials determines the mechanical support offered during the healing phase and the degree of tissue reaction. This guide outlines key differences between absorbable and non-absorbable sutures, how each behaves in veterinary surgery, how tissue type influences selection, and which Strouden products match clinical needs effectively.
Veterinary sutures are categorized based on their durability, origin, and filament structure. Regardless of the type selected, the objective remains consistent: achieve stable wound closure with minimal tissue trauma and predictable healing.
Sutures are typically classified by absorption behavior, natural or synthetic origin, filament structure such as monofilament or multifilament design, and suture size, which ranges from fine options for delicate tissues to larger sizes needed for high-tension areas. Veterinarians must consider these structural differences carefully when selecting sutures for specific anatomical regions to ensure optimal healing and long-term stability.

Absorbable sutures are designed to degrade within the body over time. They maintain tensile strength long enough to support tissue during healing before undergoing hydrolysis or enzymatic breakdown.
Absorbable sutures are ideal for tissues that regain strength quickly, such as muscle, subcutaneous tissue, internal organ surfaces, and locations where only temporary mechanical reinforcement is required. After placement, these sutures gradually lose tensile strength as they undergo controlled breakdown. During this process, the surrounding tissues progressively assume structural support as natural collagen formation and tissue remodeling occur, allowing the wound to heal without the long-term presence of foreign material.
These absorbable sutures provide the controlled degradation, tissue compatibility, and strength veterinarians require in internal wound repair.

Absorbable sutures are preferred in tissues that heal rapidly or do not require prolonged mechanical support. They are particularly useful for abdominal wall and internal organ closures where the tissue regains strength quickly and long-term reinforcement is unnecessary. These sutures are also appropriate for subcutaneous layers, which benefit from temporary stability without the need for later removal. Ligature applications frequently rely on absorbable materials because they secure vessels effectively and naturally degrade once healing is established.
Pediatric veterinary patients often receive absorbable sutures due to rapid tissue turnover and the desire to avoid unnecessary follow-up procedures. Absorbable materials are also valuable in situations where suture removal is impractical or stressful for the patient, such as in anxious animals or wildlife cases. Their ability to break down naturally eliminates the need for postoperative retrieval, easing patient management and supporting a smoother recovery process.
Non-absorbable sutures maintain tensile strength indefinitely and remain in the tissue until manually removed or left permanently if appropriate.
Non-absorbable sutures are not affected by enzymatic or hydrolytic processes, allowing them to remain stable within tissue for long periods. This permanence makes them an essential choice for closures that require durable tensile strength, especially in tissues that experience significant mechanical stress during movement or healing. Their stability supports predictable outcomes in procedures where long-term reinforcement is necessary.
These sutures are commonly used for skin closures that must withstand tension, reinforcement of fascia, orthopedic surgeries, and areas of the body subject to high strain. They are also important in cardiac or vascular repairs involving a vascular prosthesis where persistent structural support is critical. Depending on the clinical need, they may be removed externally once healing progresses or intentionally left in place to provide ongoing mechanical stability.
Non-absorbable sutures remain the standard for external skin repair where visual monitoring and eventual removal are required.
Understanding the distinctions between absorbable vs non absorbable sutures helps veterinarians select the correct tool for each tissue type and healing requirement.
Absorbable materials gradually weaken as healing progresses. They are ideal when tissue regains strength quickly.
Non-absorbable sutures retain tensile strength long term, providing stability for tension-bearing areas such as: Skin, fascia and orthopedic repairs
Absorbable sutures may cause mild enzymatic or hydrolytic reactions but are generally well tolerated.
Non-absorbable sutures cause minimal irritation but can act as a foreign object if left in delicate tissues, increasing risk of granuloma formation.
Absorbable sutures support healing tissues through the repair phase before losing strength.
Non-absorbable sutures support tissues indefinitely, making them crucial for skin wounds, joints, or prosthetic stabilization.
Absorbable sutures simplify follow-up because they do not require removal.
Non-absorbable sutures require monitoring and eventual removal, depending on the procedure.
Choosing the correct suture size is essential because it influences needle handling, knot security, and the degree of tissue trauma during closure. Smaller suture sizes are best suited for delicate tissues encountered in feline or avian procedures, while medium sizes are commonly used for routine skin and soft tissue repairs. Larger sutures are reserved for orthopedic closures or high-tension sites that require stronger mechanical support.
Strouden sutures such as ASSUFIL, MONOFIL, Chromic Catgut, and ASSUNYL are available in a comprehensive range of appropriate suture sizes to match clinical needs.
Veterinarians must evaluate tissue tension, healing speed, infection risk, and surgical goals when choosing among absorbable vs non absorbable sutures.
For veterinarians, understanding the functional differences between absorbable vs non absorbable sutures is essential for achieving optimal healing, minimizing complications, and promoting long-term tissue stability. Absorbable sutures offer controlled degradation for internal wounds, while non-absorbable sutures provide lasting support for skin and high-tension areas.
At Strouden, we supply a reliable range of Assut Europe surgical sutures, including ASSUFIL (PGA), MONOFIL (PDO), Chromic Catgut, and ASSUNYL nylon sutures. These materials provide the tensile strength, precision, and biocompatibility needed across diverse veterinary procedures.

Absorbable sutures degrade naturally through enzymatic or hydrolytic processes, providing temporary wound support. Non-absorbable sutures maintain tensile strength indefinitely and must be removed or left permanently. Each is chosen based on tissue healing speed and long-term support needs.
Non-absorbable sutures provide lasting mechanical support for tissues under tension, such as skin and fascia. They are ideal for external closures requiring strength and stability during extended healing. Veterinarians remove them once wound consolidation is complete.
Dissolvable stitches soften and disappear as the body absorbs them, while non-dissolvable sutures remain visible and intact until removed. Veterinary professionals can identify suture type by material characteristics, filament structure, and expected tissue reaction.
Absorbable sutures eliminate the need for removal, reducing patient stress and follow-up visits. They support internal healing effectively and degrade gradually, preventing long-term foreign material retention within tissues.
Non-absorbable sutures may remain indefinitely unless purposefully removed. For skin closures, removal typically occurs between 7 and 14 days depending on wound location, tension, and the veterinarian’s assessment of healing progression.
