Can Hernia Mesh Be Removed? Surgery, Risks & Recovery

Hernia mesh can be removed, and thousands of these operations are performed each year for problems ranging from chronic pain to deep infection. The procedure is technically demanding because the body grows tissue into and around the mesh over time, sometimes making the implant difficult to separate from surrounding structures like blood vessels, nerves, and the abdominal wall itself. Whether removal is the right call, how the surgery is done, and what recovery looks like all depend on why the mesh is causing trouble and where it was originally placed.

Why Mesh Gets Taken Out

Most hernia repairs using mesh go well. When they don’t, problems tend to fall into two broad camps: infection and chronic pain. Infected mesh can cause abscesses, draining sinuses that won’t heal, localized swelling, fever, and skin redness over the repair site.¹ Once bacteria colonize mesh fibers and the biofilm that forms around them, antibiotics alone rarely clear the infection. At that point, taking some or all of the mesh out becomes the most reliable path to resolution.

Chronic pain after hernia repair is the other major driver. Surgeons sometimes find that the mesh has wrinkled, balled up into a hard lump called a meshoma, or become tangled with nearby nerves. One study of patients undergoing laparoscopic mesh removal for groin pain found wrinkled mesh in about half the cases and meshomas in roughly a third.² Less common reasons for removal include mesh erosion into nearby organs, mesh contraction that distorts tissue, and allergic-type reactions to the implant material.

Trying Non-Surgical Treatment First

Except for active infection or mesh erosion, surgeons generally try non-surgical options before jumping to removal. Current guidance suggests a tiered approach that starts with the least invasive steps and escalates only when those fail. That can include pain medications, nerve blocks, physical therapy, and psychological support for pain management.³ If you’ve been dealing with chronic post-hernia-repair pain, the usual advice is to give these conservative measures a fair trial before considering a second operation. If they don’t work after several months, mesh removal enters the conversation.

How Surgeons Diagnose Mesh Problems

Before anyone goes back in, imaging helps clarify what’s happening. CT scans are the most common first step, and MRI or ultrasound fill in when CT isn’t enough. These scans can reveal mesh migration, fluid collections around the implant, or signs of infection, though mesh visibility on imaging varies depending on the type of material.⁴ Your surgeon is looking for concrete evidence that the mesh itself is the source of the problem rather than some other post-surgical issue. This diagnostic step matters because the surgery to remove mesh carries its own risks, so you want to be reasonably sure it will actually fix the complaint.

Open, Laparoscopic, or Robotic Removal

Mesh removal can be done through an open incision, through small laparoscopic ports, or with a robotic-assisted approach. The choice depends largely on where the mesh sits, how much tissue has grown into it, and the surgeon’s experience.

For groin mesh placed through an open anterior repair, open removal is often the most direct route. The surgeon reopens the groin, identifies key landmarks, lifts the mesh off the underlying muscle layer, and carefully separates it from structures like the spermatic cord in men. If nerves are stuck to the mesh, they may need to come out with it.⁵ The resulting gap where the hernia may recur is then closed with a tissue-based repair.

When the original mesh was placed laparoscopically behind the abdominal wall, going back in through small ports can make sense. Both standard laparoscopic and robotic approaches have been shown to reduce preoperative pain and are considered viable options in experienced hands, though both carry a risk of vascular and nerve injury. In a direct comparison, operative time was shorter with the standard laparoscopic technique than with the robotic approach.⁶ Robotic surgery offers the advantage of better instrument articulation, which can help with fine dissection around delicate structures.

There’s no single “best” method. The right approach is the one that gives the surgeon the clearest view and safest access to the mesh in your particular situation. If you’re evaluating surgeons, ask how many mesh removals they’ve done and which approach they plan to use for your specific anatomy.

Complete Versus Partial Removal

One of the bigger decisions during the operation is whether to take all the mesh out or leave behind the portions that are deeply embedded in tissue and not obviously causing trouble. This question matters most in infected cases, because bacteria hiding in retained mesh can keep the infection smoldering.

The evidence leans toward complete removal when infection is the reason for the surgery. A propensity-matched comparison found that partial removal led to higher complication rates than complete removal, including more wound problems and more than triple the reoperation rate in patients with mesh infection or fistulas.⁷ A systematic review found that persistent infection lingered in over half of patients who had only partial removal.⁸

That said, partial removal isn’t always wrong. Sometimes the mesh is so thoroughly incorporated into the abdominal wall that tearing all of it out would mean removing large sections of tissue and creating a defect too big to close. In those situations, surgeons weigh the risk of persistent infection against the risk of a devastating wound. For chronic pain cases without infection, partial removal targeting the problematic area may be enough if the rest of the mesh is well incorporated and painless.

Risks During the Operation

Mesh removal is harder than the original hernia repair. Scar tissue obscures normal anatomy, and the mesh may be stuck to blood vessels, nerves, the bladder, or the vas deferens in men. In one study of laparoscopic inguinal mesh removal, about one in five patients had an intraoperative complication, including injury to the inferior epigastric artery, the vas deferens, and the bladder.⁹ These injuries can usually be repaired during the same operation, but they underscore why this surgery benefits from a surgeon who does it regularly.

For ventral or abdominal wall mesh removal, the stakes can be even higher because the mesh may be stuck to bowel. Inadvertent bowel injury during dissection is a recognized risk, and the operation sometimes takes several hours in complex cases. Postoperative complications are common: one study of infected ventral mesh removal found that roughly six in ten patients developed some form of postoperative complication.¹⁰

Does Removing the Mesh Actually Help Pain?

This is the question that matters most to people who are living with chronic pain after hernia repair. The short version: most patients get meaningful relief, but not everyone does.

In a study of laparoscopic mesh removal for groin pain, about six in ten patients reported complete pain relief and another third reported partial improvement, with significant drops in validated pain scores at a median follow-up of eight and a half months.⁹ A study of robotic mesh removal found similar numbers, with about 59% of patients reporting improvement or resolution of pain after the procedure.¹¹

Those numbers are encouraging but not a guarantee. Roughly one in three patients still has some degree of ongoing pain after mesh removal. Chronic pain can involve changes in the nervous system that persist even after the original irritant is gone, which is one reason surgeons push for a thorough non-surgical trial first. Patients who’ve had pain for many years before mesh removal may be less likely to achieve complete relief, though this is an area where better data is still needed.

When Nerve Removal Is Done Alongside Mesh Removal

For groin pain specifically, the problem isn’t always the mesh alone. Nerves running through the inguinal canal can get trapped, cut, or irritated by the mesh or the scar tissue around it. When a surgeon suspects nerve involvement, they may recommend removing one or more of the inguinal nerves during the same operation.

A meta-analysis comparing different neurectomy strategies found that removing all three inguinal nerves (triple neurectomy) had the highest overall pain improvement rate at about 98%, while removing two nerves had the highest rate of complete pain relief at around 80%.¹² The tradeoff is permanent numbness in the groin area, which most patients consider acceptable compared to the pain they were living with.

A long-term follow-up study found that pain intensity scores remained significantly lower three years after mesh removal with selective neurectomy compared to preoperative levels, dropping from a median of 6 out of 10 before surgery to 3 out of 10 at 36 months. Only one patient out of eight in that cohort experienced worse pain over time.¹³ The fact that relief held up at three years is reassuring, since short-term pain improvement after any surgery can sometimes fade.

Hernia Recurrence After Mesh Removal

Once the mesh is out, you no longer have the reinforcement it was providing in the first place. That means the hernia can come back, and recurrence rates after mesh removal are real. How surgeons handle this depends on the clinical situation.

If the mesh was removed for infection, surgeons face a dilemma: putting new synthetic mesh into a contaminated field risks another infection, but leaving the repair without any reinforcement risks recurrence. One approach uses biological mesh, made from processed animal tissue, as a bridge. In a case series where infected synthetic mesh was replaced with porcine-derived biological mesh, about one in five patients developed a recurrent hernia during a follow-up period averaging nearly three years.¹⁴ Patients who needed bridging (where the gap was too large to close the muscle edges) and those who developed postoperative infections had higher recurrence rates.

For inguinal mesh removed because of pain rather than infection, the tissue repair performed at the time of removal carries its own recurrence risk. Some surgeons use a tension-free tissue suture technique to close the defect, while others may place new mesh if the surgical field is clean. There is no one-size-fits-all answer, and this is a conversation worth having with your surgeon before the operation.

Recovery and Hospital Stay

Recovery from mesh removal is generally slower than recovery from the original hernia repair. How long you stay in the hospital depends on whether the procedure was minimally invasive or open, and whether the abdominal wall needed reconstruction. For ventral mesh removal with simultaneous hernia repair, one study reported a median hospital stay of about a week to ten days.¹⁰ Laparoscopic or robotic inguinal mesh removal tends to involve a shorter stay, sometimes just one or two nights.

At home, expect several weeks of limited activity. Heavy lifting is typically restricted for at least six weeks, though your surgeon’s instructions will depend on the extent of the dissection and whether a new repair was performed. Wound care is especially important if the removal was for infection, as the incision may be left partially open to heal from the inside out (secondary intention) rather than closed with stitches.

Quality of Life After the Procedure

Beyond pain scores, researchers have looked at broader quality-of-life measures. In a study following patients for three years after removal of infected inguinal mesh, quality-of-life scores, pain scores, and anxiety scores all improved significantly compared to before surgery.¹⁵ That improvement in anxiety is worth noting. Living with a chronic infection or unrelenting pain after a surgery that was supposed to fix a problem takes a real psychological toll, and resolving the physical issue often lifts that burden too.

What Happens to Mesh Inside the Body Over Time

One question people often have is whether the mesh changes after it’s been in the body for years. The answer is yes. A study analyzing polypropylene mesh explants removed anywhere from six months to thirteen years after implantation found measurable changes in essentially every sample. Every single mechanically tested sample showed altered stiffness compared to unused mesh, about three-quarters showed surface chemical changes, and about a third had shifts in crystallinity.¹⁶ The degree of change varied with factors like how the mesh was placed and whether infection was present.

The body also mounts an ongoing immune response to the mesh, even when things are going well clinically. Microscopy of tissue around explanted polypropylene mesh shows chronic inflammation with immune cells like macrophages still present at the mesh-tissue boundary years after implantation.¹⁷ Different mesh materials provoke different levels of reaction. Examination of explanted meshes from a single patient who had polypropylene, expanded PTFE, and polyester implants showed that expanded PTFE kept surrounding tissue from growing into it, while polyester integrated more with the host tissue but still triggered a chronic granulomatous inflammatory reaction with giant cells and immune cells interspersed throughout.¹⁸

None of this necessarily means the mesh should come out if it’s not causing symptoms. A low-grade foreign body response is expected with any permanent implant and doesn’t by itself indicate a problem. But these findings do help explain why some patients develop late-onset complications years after an initially successful repair, and why mesh that’s been in place for a long time can be harder to remove than mesh implanted recently.

The Financial Side

Mesh removal is expensive. A study comparing costs found that the median hospital bill for mesh removal from a ventral hernia was roughly $24,000, nearly double the roughly $13,000 median cost of the original hernia repair that put the mesh in.¹⁹ Those figures don’t even account for the costs of readmissions, reoperations, and follow-up care that many patients need afterward. Insurance coverage varies. If the removal is for a documented medical indication like infection or intractable pain, most insurers cover it, but getting prior authorization and navigating appeals can be its own ordeal. If you’re considering mesh removal, contact your insurer early and have your surgeon’s office provide the clinical documentation that supports the medical necessity.

Finding the Right Surgeon

Mesh removal sits in a niche corner of surgery. Not every general surgeon who performs hernia repairs is experienced with taking mesh out. The dissection is more complex, the anatomy is distorted by scar tissue, and the reconstruction afterward requires comfort with techniques that many surgeons don’t use regularly. Centers that specialize in abdominal wall reconstruction or that run dedicated hernia programs tend to have the most experience. Before committing to surgery, it is reasonable to ask the surgeon how many mesh removals they’ve performed, what approach they plan to use, what their complication and recurrence rates look like, and whether they perform neurectomy when nerve involvement is suspected. A surgeon who does this work routinely will have straightforward answers to all of those questions.
