Dissolvable Stitches, Steri-Strips and Surgical Glue: What to Expect as You Heal

Almost every question I get in the first fortnight after surgery is about the closure rather than the surgery itself. Something has poked through, or curled up, or come off earlier than expected, and it looks wrong.

Most of the time it is not wrong. This is a plain guide to what each type of closure does and how it behaves while you heal — and, more importantly, what does warrant a phone call.

Dissolvable stitches

Also called absorbable sutures. The material is designed to be broken down by the body over a period of weeks, so there is nothing to remove. They are commonly placed beneath the skin surface, where they hold the deeper layers together while the wound gains its own strength.

How long they last depends on the material. Some are largely gone within a week or two; others are chosen deliberately to persist for six to twelve weeks in areas under more tension, such as the abdomen. Your surgeon selects the material for the job, not for your convenience.

What surprises people most is spitting sutures — a small end of suture material working its way to the surface and poking through, sometimes weeks after surgery, often with a tiny spot of redness around it. It feels like a bristle. It is common, it is not an infection in itself, and it usually resolves once the fragment is removed or works its own way out.

Steri-Strips

Thin adhesive strips laid across the closed wound. They do not hold the wound together by themselves — the sutures beneath do that. What they do is support the surface, take tension off the very edges of the skin, and protect the line while it seals.

They are usually left in place for one to two weeks and allowed to lift off gradually as the adhesive weakens. Edges curling up first is entirely normal, and a strip coming away at one end while the middle stays stuck is not a problem.

• Do not peel them off early because they look untidy — they are doing quiet work at the point where scars widen.
• If one falls off completely and the wound beneath looks clean and closed, that is generally fine. Mention it at your next check.
• Follow your surgeon's instructions on showering. Some are happy for strips to get briefly wet and be patted dry; others are not. Do not guess.
• Mild itching under the strips is common. Redness that extends well beyond the strip is not.

Surgical glue

A skin adhesive painted over the closed wound, which sets into a flexible film. It seals the surface, acts as its own waterproof barrier, and removes the need for a surface dressing in many cases.

Over one to three weeks it flakes and peels away in small pieces as the skin beneath renews itself. This can look alarming — like the wound is coming apart — when what is actually happening is that a plastic-like film is separating from healed skin.

• Let it come off on its own. Picking at it can lift skin that is not ready.
• Do not scrub the area or apply creams, oils or ointments over it unless your surgeon has told you to.
• It often peels unevenly, so part of the line can look bare while the rest is still sealed. That is normal.

A rough timeline

What is normal in the first two weeks

• A firm ridge along the scar line. Healing tissue is denser than surrounding skin and softens over months.
• Pink or red discolouration along the line. Scars generally look their worst somewhere between four and eight weeks before improving over six to twelve months.
• Itching, tingling, or patches of numbness near the wound.
• Small amounts of clear or lightly blood-tinged ooze in the first few days.
• Bruising that spreads downwards with gravity and changes colour as it clears.
• Mild tightness when you move, particularly across the abdomen or chest.

What is not normal

Contact your surgeon or seek medical attention promptly if you notice any of the following. None of these should be watched overnight to see if they improve.

• Spreading redness moving outward from the wound, or red streaking away from it.
• Increasing pain after day three, rather than steadily decreasing pain.
• Thick, cloudy, yellow or green discharge, or a bad smell from the wound.
• Fever, chills, or feeling generally unwell.
• The wound edges separating, or a gap appearing in a line that was closed.
• A sudden increase in swelling, or a firm, tense, expanding area near the wound.
• Skin around the wound that turns dark, dusky or black.
• Any calf pain, swelling or tenderness, or shortness of breath or chest pain — these are not wound problems and need urgent assessment.

Helping the scar over the longer term

Once the wound is fully sealed and your surgeon confirms you can start, three things have reasonable support behind them: keeping the scar out of direct sun for the first year, using silicone gel or sheeting consistently, and gentle massage along the line once it is comfortably tolerated.

None of these produces a dramatic change and all of them require months of consistency. Scars mature slowly, and judging a scar at eight weeks is judging it at its worst.
