Minimally Invasive Surgery: 5 Myths Patients Still Believe (And the Truth)

When a surgeon recommends minimally invasive surgery, most patients go home and do what everyone does, they ask around. A family member who had open surgery twenty years ago. A neighbour who heard something about keyhole surgery going wrong. Something half-read on the internet at midnight that raised more questions than it answered.

By the next consultation, the patient arrives with a head full of concerns that are more myth than fact. And because these myths sound plausible, they have just enough truth-adjacent logic to seem credible they’re surprisingly hard to shake without a clear, direct conversation about what minimally invasive surgery actually is and isn’t.

So here are the five most common myths about minimally invasive surgery that patients still believe and the straightforward truth behind each one.

Myth 1: “Keyhole Surgery Is Only for Minor Procedures”

This is probably the most widespread misconception, and it stems from the early days of laparoscopic surgery when the technique really was limited to simpler procedures like gallbladder removal. Word got around that keyhole surgery was fine for small things but that anything serious needed a proper open operation.

That was true in 1990. It hasn’t been true for a long time.

The truth: Minimally invasive surgery is now used for a broad and growing range of complex procedures colorectal cancer resection, hernia repair, hysterectomy, bariatric surgery, splenectomy, adrenal gland removal, liver resection, and more. The complexity of a procedure doesn’t determine whether it can be done laparoscopically, the surgeon’s training, the available equipment, and the specific anatomy of the patient do.

In fact, for certain complex pelvic and abdominal procedures, the laparoscopic approach actually offers better visualisation than open surgery. The magnified, high-definition camera view inside a laparoscopic procedure gives surgeons a level of detail that isn’t always possible when working through a large open incision at a greater distance from the operative field.

The range of what’s possible with minimally invasive techniques has expanded dramatically over the past two decades and continues to expand. Dismissing it as suitable only for minor cases reflects a view of the technique that’s decades out of date.

Myth 2: “The Recovery Is the Same as Open Surgery Just with Smaller Scars”

This one comes from a place of genuine scepticism, the idea that the inside of the body doesn’t know or care about the size of the incision, so recovery should be the same regardless. The smaller cuts are just cosmetic, right?

The truth: The difference in recovery between minimally invasive and open surgery is significant, and it goes well beyond the appearance of the scar.

When open surgery is performed, the surgeon works through a large incision that cuts through multiple layers of skin, muscle, and connective tissue. The body’s response to this is substantial inflammation, pain, and a healing process that involves every layer of tissue that was disrupted. The muscles of the abdominal wall, in particular, take considerable time to recover from being cut through.

With laparoscopic surgery, the same internal procedure is performed through small openings that don’t cut through major muscle layers. The surrounding tissue is largely undisturbed. The body’s inflammatory response is proportionally smaller and this is what drives the real differences in recovery:

• Significantly less post-operative pain often managed with oral medication rather than intravenous analgesia
• Shorter hospital stay many laparoscopic procedures are day cases or overnight stays
• Faster return to eating, moving, and normal activity
• Lower risk of wound complications like infection and dehiscence
• Less risk of post-operative complications linked to immobility blood clots, chest infections

For a patient who needs to return to work, care for children, or manage daily responsibilities, the difference between one week of recovery and six weeks of recovery isn’t cosmetic. It’s practically significant in a very real way.

Myth 3: “Laparoscopic Surgery Is Less Safe Because the Surgeon Can’t Feel What They’re Doing”

This concern comes up often, and it’s understandable. Open surgery involves the surgeon’s hands directly in the operative field, they can feel tissue, assess tension, and make tactile judgements in real time. Laparoscopic surgery uses instruments passed through small ports, with the surgeon watching a monitor. Doesn’t that mean something important is lost?

The truth: The absence of direct tactile feedback in laparoscopic surgery is a real limitation, but it’s one that experienced laparoscopic surgeons are specifically trained to compensate for. And it’s more than compensated by what the laparoscopic approach provides in return.

The camera inside a laparoscopic procedure shows the operative field at a level of magnification and clarity that the human eye working through an open incision simply can’t match. Structures that might be difficult to see in an open field, fine blood vessels, nerve pathways, tissue planes are clearly visible on the monitor. This visual precision, in experienced hands, more than compensates for the reduced tactile feedback.

What matters for surgical safety is training and experience. A surgeon with extensive laparoscopic training operating within their competence is operating safely regardless of whether their hands are directly in the field or working through ports. An inexperienced surgeon working with any technique is less safe. The technique doesn’t determine safety, the surgeon’s skill and experience with that technique does.

It’s also worth noting that complication rates for laparoscopic procedures, when performed by appropriately trained surgeons, are consistently comparable to or lower than those for open surgery with lower rates of wound infection and post-operative complications in particular.

Myth 4: “If Something Goes Wrong, It’s Harder to Fix During Keyhole Surgery”

This one taps into a fear that’s understandable, if the surgeon is working through small holes with a camera and instruments, surely it’s harder to respond to an unexpected finding or a complication than if they had full open access?

The truth: This misunderstands how laparoscopic surgery actually works, and it misunderstands what conversion to open surgery means when it happens.

First experienced laparoscopic surgeons are trained to manage complications within the laparoscopic approach. Bleeding, unexpected anatomy, tissue that’s more fragile than expected, all of these are encountered and managed laparoscopically when the surgeon has adequate training and experience. The instruments available through a laparoscopic port include suction, irrigation, electrocautery, clipping devices, and suturing, everything needed to respond to most intraoperative situations.

Second, when conversion to open surgery does happen, it’s not a failure or an emergency. It’s a planned, controlled decision made by the surgeon when they determine that the safest course for the patient is to complete the procedure through an open incision. This might be because of unexpected scar tissue from previous surgery, anatomy that’s more complex than imaging suggested, or bleeding that’s more safely managed with direct access. The decision is made calmly, in the patient’s best interest, and the open approach is immediately available.

The rate of conversion from laparoscopic to open surgery varies by procedure and patient factors, but in the hands of an experienced surgeon operating on an appropriate patient, it’s low. And when it does happen, the patient is not worse off for having started laparoscopically, they’re better off for having a surgeon who made the right call at the right time.

Myth 5: “Minimally Invasive Surgery Is a New, Unproven Technique I’d Rather Wait Until It’s More Established”

This concern tends to come from older patients, or from family members who are cautious about anything that sounds modern or technological. The reasoning goes, open surgery has been around for over a century. Keyhole surgery is newer. Newer means less proven. Why take the risk?

The truth: Laparoscopic surgery isn’t new. It’s been performed routinely since the late 1980s and early 1990s. The first laparoscopic cholecystectomy, gallbladder removal was performed in 1987. That’s nearly four decades of clinical experience, hundreds of millions of procedures worldwide, and an enormous body of evidence on outcomes, safety, and long-term results.

In surgical terms, laparoscopic surgery is an established, mature technique. It isn’t experimental. It isn’t on the cutting edge in the sense of being unproven. For many procedures gallbladder removal, appendectomy, hernia repair, it’s now the standard of care, meaning it’s the approach most surgeons would choose as the default rather than a specialist option.

The perception of it being “new” persists partly because the visible aspect of it no large scar, shorter hospital stay, faster recovery, still surprises people who are comparing it to their experience or their relatives’ experience of open surgery from years past. But the technique itself has decades of evidence behind it.

If anything, patients who are hesitant about laparoscopic surgery because it seems new should consider the inverse question, in a world where the minimally invasive approach is the established standard for their procedure, choosing open surgery because it feels more familiar means choosing an approach associated with more tissue trauma, longer recovery, and higher complication rates, without a safety benefit to justify it.

The Broader Point

These five myths share a common thread, they’re all based on an outdated or incomplete picture of what minimally invasive surgery is. The technique has changed dramatically since it first appeared, the training surgeons receive has become more rigorous, the instruments have become more precise, and the evidence base has grown to the point where laparoscopic surgery is the preferred approach for a wide range of conditions.

That doesn’t mean it’s right for every patient or every situation. There are genuine clinical reasons why open surgery is sometimes the better choice patient anatomy, previous surgeries creating significant adhesions, emergency situations, or the specific nature of the procedure. A good surgeon is honest about this and recommends the approach that’s best for the individual patient, not the approach that fits a preference or a myth.

What patients deserve is accurate information not reassurance that ignores their concerns, but a clear explanation of what minimally invasive surgery actually involves, what its genuine advantages are, and where its limitations lie.

Our surgical team takes the time to walk patients through exactly this addressing concerns directly, explaining the reasoning behind the recommended approach, and making sure that the decision made is an informed one. If you’ve been recommended minimally invasive surgery and have questions or concerns, come in for a consultation. Most myths dissolve pretty quickly when the facts are laid out clearly.
