What Happens If Stitches Are Left In Too Long?

Stitches, also known as sutures, are medical devices used to hold together the edges of a wound or incision, promoting healing and reducing complications like bleeding or infection. They are a temporary measure, placed to provide structural support while the body’s natural healing processes take over. Timely removal is important for optimal wound recovery, as prolonged presence can interfere with skin integrity and healing. Different types exist, some dissolvable and others requiring manual removal after a specific period.

Immediate Consequences of Over-retained Stitches

Leaving stitches in place beyond their recommended removal time can lead to several problems at the wound site. A significant concern is increased susceptibility to infection, as stitches can create tiny pathways for bacteria to enter the healing tissue. Microbes can thrive beneath the skin, potentially causing localized infections or abscesses (collections of pus).

Prolonged stitch presence frequently contributes to more prominent scarring. When stitches remain in the skin too long, they can cause continued inflammation around the wound edges. This irritation interferes with natural tissue remodeling, potentially leading to exaggerated scar marks, indentations, or keloids.

Over-retained stitches can cause ongoing pain and discomfort. The constant presence of the suture material can irritate the healing skin, leading to tenderness, itching, or a pulling sensation. If left too long, they can become embedded as new tissue grows around them, making removal more challenging and potentially causing additional pain.

The Body’s Response to Prolonged Stitch Presence

The body reacts to the presence of stitches as a foreign material, and this reaction intensifies with prolonged presence. One common biological response is tissue ingrowth, where surrounding tissues grow around and into the stitch material. This embedding makes removal difficult and can cause additional tissue damage.

Another physiological response is a foreign body reaction, the immune system’s attempt to isolate or reject the material. Macrophages, a type of white blood cell, accumulate around the suture and sometimes fuse to form multinucleated giant cells. This immune activity results in chronic inflammation around the stitch site, contributing to discomfort and delaying healing.

The physical presence of the stitch can also cause continuous local irritation. Even if not infected or deeply embedded, the tension or friction from the suture material against the healing skin can provoke a persistent inflammatory response. This constant mechanical irritation further contributes to tissue damage and can impede wound closure and maturation.

Recognizing Problems and Seeking Care

It is important to be aware of specific signs that may indicate stitches have been left in too long or that complications are developing. Observable signs include increased redness around the stitched area, swelling, or a noticeable increase in pain or tenderness at the wound site. The presence of pus, clear or discolored discharge, or a foul odor from the wound are also indicators of a potential infection. A fever or chills, along with the wound appearing to gape open, also warrant immediate attention.

Individuals should always adhere to the recommended timeline for stitch removal provided by their healthcare professional and attend all scheduled follow-up appointments. If stitches are still present past this recommended date, or if any signs of complications are observed, it is important to contact a healthcare professional promptly. Attempting to remove stitches at home is not advised, as this can introduce bacteria, cause further injury, or lead to incomplete removal, potentially worsening any existing issues.
