Absorbable sutures are surgical threads designed to break down naturally in the body once a wound has healed, which means no second visit, no removal appointment, and one less thing for the patient to worry about. For the surgeon, though, the real question isn’t whether to use an absorbable suture material; it’s which one, because a suture that dissolves too fast in fascia or too slow in mucosa can quietly undo an otherwise perfect closure.
This guide is meant to close that gap. Whether you’re closing a GI anastomosis, a subcuticular skin layer, or a hernia repair, the material you pick determines how much tensile strength is still around on day 14, day 28, or day 42, and that timing matters more than most people give it credit for.
What Exactly Counts as an Absorbable Suture Material?
Every absorbable suture material falls into one of two families:
Natural absorbable sutures:
Made from purified collagen (catgut). The body’s enzymes break them down through phagocytosis, which tends to trigger a slightly stronger tissue reaction but works well in tissues that heal quickly.
Synthetic absorbable sutures:
Polymers like polyglactin 910, poliglecaprone 25, or polydioxanone. These dissolve through hydrolysis, a slower and far more predictable process, which is why most modern absorbable stitches used in general, GI, gynaecological, and plastic surgery are synthetic.
The difference isn’t academic. It decides how a suture handles in your hand, how it sits in tissue, and how long it holds the wound edges together before quietly disappearing.
Absorbable Sutures That Actually Show Up on the OT Table: Aqmen’s Range
Every one of Aqmen’s absorbable sutures is manufactured and quality-checked at every production stage before it reaches you, so here’s how the range breaks down by material and use case.
Suture | Material | Structure | Wound Support | Best suited for |
Catgut (Plain & Chromic) | Twisted multifilament | 21 days | GI, obstetric, gynaecological, general, urological surgery | |
AQsolve® / Polysolve 910™ | Polyglactin-910 | Braided & coated | 28 days | Oral, ophthalmic, GI, obstetric, gynaecological, general, plastic surgery |
AQfast® / Polysolve Fast™ | Polyglactin-910 (fast absorbing) | Braided & coated | 14 days | Obstetric, plastic, gynaecological, paediatric, urological surgery |
Polyglactin-910 with antibacterial triclosan | Braided & coated | 28 days | Same applications as AQsolve, with added antibacterial protection at the wound site | |
Poliglecaprone 25 | Monofilament | 21 days | GI, plastic, gynaecological, general, urological surgery, especially subcuticular closures | |
Polydioxanone | Monofilament | 42 days | Orthopaedic, ophthalmic, GI, obstetric, gynaecological, general, plastic, abdominal surgery |
A few things worth noticing here. AQgut still earns its place on the tray for procedures where fast, biologic absorption is exactly what you want. AQfast and Polysolve Fast exist for the opposite reason: obstetric and paediatric cases where you need adequate support and nothing more, so the suture clears out quickly. And AQPDsyn’s 42-day wound support window is what makes it the material of choice when you’re closing fascia or abdominal wall layers that need to stay strong well past the two-week mark.
Benefits of Absorbable Sutures Beyond “It Dissolves”
The obvious benefit of absorbable sutures is that they save the patient a removal visit. But the benefits of absorbable sutures go further than that, and most surgeons already feel this in practice even if it’s never written down:
1. Fewer complications tied to a foreign body sitting in tissue long-term: Once healing is done, the suture starts disappearing too.
2. Better outcomes in internal and mucosal tissue: Where a non-absorbable material would need a second procedure just to get it out.
3. Predictable strength curves: A material like AQPDsyn is engineered to lose strength at a known, gradual rate, so you’re closing with a plan, not a guess.
4. Reduced post-op discomfort: Since there’s no removal-related pain or repeat trauma to the healing wound.
5. Smoother handling and knot security: Aqmen’s braided absorbable stitches are coated specifically to reduce tissue drag and give a cleaner knot tie-down, which shows up in your suturing time as much as your outcomes.
How Long Do Absorbable Sutures Take to Dissolve?
This is the question every resident asks and every consultant has an opinion on, so here’s the honest, two-part answer.
Wound support time is how long the suture holds meaningful tensile strength, this is what Aqmen lists for each material above (14 to 42 days). Complete absorption is how long it takes for the material to disappear from the body entirely, and that window runs considerably longer. Published suture literature puts polyglactin 910 at roughly 60 to 90 days for full absorption, poliglecaprone 25 at around 90 to 120 days, and polydioxanone anywhere from 180 to over 200 days, with plain catgut clearing the fastest of the group.
In short: how long do absorbable sutures take to dissolve depends entirely on the material, not a fixed number you can quote across the board. That’s exactly why picking the right absorbable suture material for the procedure, not just any dissolvable option, is the decision that actually matters.
Matching the Absorbable Suture to the Procedure
A quick way to think about it chairside:
1. Need it gone fast, minimal support required? AQfast or Polysolve Fast (14 days).
2. Standard soft tissue approximation, general and GI work? AQsolve or Polysolve 910 (28 days).
3. Subcuticular or cosmetically sensitive closures? AQmono, for its monofilament structure and low tissue reaction.
4. Fascia, abdominal wall, or slow-healing tissue? AQPDsyn, for the extended 42-day support window.
5. Contaminated or infection-prone sites? Polysolve+, for the added triclosan protection.

The Takeaway
Absorbable sutures aren’t a single product, they’re a decision tree, and the right answer changes with the tissue, the timeline, and the risk profile of the case. Aqmen’s absorbable suture range, from AQgut through to AQPDsyn, is built so that decision comes down to matching wound support windows to the procedure, not settling for whatever’s left on the shelf.
Frequently Asked Questions
Absorbable sutures are made from either natural collagen (catgut) or synthetic polymers such as polyglactin-910, poliglecaprone 25, or polydioxanone. The material determines how the absorbable suture behaves in tissue and how long it lasts before dissolving.
Initially, yes, many absorbable stitches match or exceed the tensile strength of non-absorbable sutures at the time of closure. The difference is that absorbable materials are designed to gradually lose strength on a predictable schedule as the wound heals.
It depends on the absorbable suture material. Fast-absorbing options like AQfast provide about 14 days of wound support, while AQPDsyn (polydioxanone) extends to 42 days of support, with full absorption of these absorbable stitches taking considerably longer for both.
Scarring depends more on suture placement, tension, and wound care than on whether the suture is absorbable. Monofilament absorbable sutures like AQmono are often chosen for cosmetically sensitive areas because of their smooth passage and minimal tissue reaction.
Yes, with the right absorbable suture material. Polysolve+ is coated with antibacterial triclosan specifically for cases where added protection at the suture site is a priority, one of the practical benefits of absorbable sutures in contamination-prone procedures.
