For most common cancers, minimally invasive surgery cures about as many patients as open surgery does. In colon and rectal cancer, laparoscopic vs open cancer surgery studies show the same survival and recurrence, and patients go home sooner with less pain. Early cervical cancer is the exception. Open radical hysterectomy gave better survival there. So the cancer type, its stage and the surgeon’s experience all matter.

Prof. Dr. Sandeep Nayak, Surgical Oncologist at MACS Clinic, Bangalore, explains how minimally invasive oncology and open surgery are weighed against each other. “Keyhole and robotic surgery suit many cancers. For some, open surgery is still the better operation. Newer doesn’t mean better. What counts is which approach clears that cancer best at that stage. Where results are equal, the gentler approach is usually chosen. Where they aren’t, the better approach is used.” 

For several common cancers, large studies show the two approaches control cancer equally well.

Colon and rectal cancer: Pooled reviews find no significant difference in disease free survival, local recurrence or spread. Short term recovery is better after laparoscopic and robotic surgery.

Surgeon experience: Equal results come from experienced teams. Both laparoscopic and robotic surgery have a steep learning curve, so volume matters.

Recovery: Smaller cuts mean less blood loss, less pain, fewer wound problems and a shorter hospital stay.

Complicated cases: Open surgery is still preferred when the colon is perforated, blocked or bleeding.

Case by case: Which cancers suit the keyhole route is worked out case by case. Our page on laparoscopic cancer surgery covers where it’s used.

Equal results can’t be assumed for every cancer. Early cervical cancer is the clearest example.

Early cervical cancer: In the LACC trial, disease free survival at 4.5 years was 86.0% after minimally invasive radical hysterectomy and 96.5% after open surgery. Overall survival was lower too.

What changed afterwards: Open radical hysterectomy is now widely recommended for early stage cervical cancer.

Difficult tumours: Very bulky tumours, or those pressing on nearby organs, can make an open operation the safer one.

Switching mid operation: A surgeon may convert from keyhole to open if it isn’t safe to continue. That’s sound judgment, not a failed operation.

Which operation is needed depends mainly on the size of the tumour, the risk level and whether it has spread. Hemithyroidectomy removes one lobe of the thyroid, and total thyroidectomy removes the whole gland. Small, low risk papillary thyroid cancers often need only the lobe with the tumour. Larger tumours, spread beyond the thyroid or involved lymph nodes usually call for total thyroidectomy. The final advice is made case by case.

Prof. Dr. Sandeep Nayak, Surgical Oncologist at MACS Clinic, Bangalore, explains how the extent of thyroidectomy is decided for papillary thyroid cancer. “The operation is matched to the cancer. Tumour size, spread beyond the thyroid and lymph node findings guide the extent of surgery. A smaller operation suits some low risk tumours. A larger one suits others. Neither is the better choice in every case.”

Both remove thyroid tissue. What differs is how much, and what follows.

Hemithyroidectomy: One lobe, and sometimes the narrow bridge of tissue joining the lobes, is removed. The other lobe stays and often keeps making enough thyroid hormone.

Total thyroidectomy: The whole gland is removed. Daily thyroid hormone tablets are needed for life afterwards.

Radioactive iodine: This treatment is given after total thyroidectomy when it’s needed. It generally isn’t given after hemithyroidectomy alone.

Second operation: If the final pathology report shows higher risk features, the other lobe may be removed in a second operation, called completion thyroidectomy. For low risk findings it’s not always needed.

Risks: Low calcium and voice changes are more likely after total thyroidectomy than after removing one lobe. These risks are part of the planning. Our page on thyroid cancer treatment covers the options.

The table sets out the main differences side by side.

Under 1 cm: For a small tumour confined to the thyroid, with no node spread, guidelines advise removing one lobe unless there’s a clear reason to remove both.

Between 1 and 4 cm: Either operation can be appropriate when the tumour hasn’t spread beyond the thyroid and no nodes are involved. Other risk factors and patient preference decide the choice.

Over 4 cm, or spread: A tumour over 4 cm, visible spread beyond the thyroid, involved lymph nodes or distant spread usually means total thyroidectomy.

Evidence: Studies of carefully selected low risk patients found limited surgery to be an equivalent strategy. Our blog on whether thyroid cancer is curable with surgery covers the outlook after treatment.

Key Takeaways

• Hemithyroidectomy removes one lobe, and total thyroidectomy removes the whole gland.
• Small, low risk papillary thyroid cancers often need only the lobe with the tumour. Larger tumours, spread beyond the thyroid or involved nodes usually need total thyroidectomy.
• Total thyroidectomy needs lifelong thyroid hormone tablets and allows radioactive iodine when it’s needed.
• The right operation depends on the individual case, so it’s worth discussing the options with a specialist.

All three remove the thyroid, either part of it or the whole gland. What changes is how the surgeon gets in, what they see while working, and how they move the instruments. Open surgery goes through a cut on the front of the neck. Endoscopic and robotic thyroid surgery reach the gland from somewhere else, like the armpit, the breast or the mouth, so the neck stays clear of a scar.

Prof. Dr. Sandeep Nayak, surgical oncologist in Bangalore with over 24 years of experience, says it’s less about which one is “best” and more about which one fits the person on the table: “Patients usually walk in having already picked a favourite, mostly based on the scar. The scar matters, and I take it seriously. But tumour size, the thyroid itself, and what the neck looks like on imaging have to lead to the decision, and the technique follows from that.”

There’s no single winner here. A few things usually push the decision one way or the other:

• A larger tumour, or one that has spread to nearby tissue, often points toward open surgery
• Suspicious lymph nodes in the neck can make open access the safer route
• A small, well-contained nodule is where robotic thyroid surgery tends to work best
• Someone who is very concerned about a visible neck scar may lean toward a remote access approach
• A very large thyroid gland can make remote access harder to do safely
• Budget and hospital availability matter too, and it’s fair to bring them up in the consultation

Whichever way it goes, cure comes first and cosmetic outcome second. If you’d like to understand how surgery fits into the bigger picture of thyroid cancer care, our post on whether thyroid cancer is curable with surgery is a good place to start.

Here’s the side by side view of the thyroidectomy types, so you can see where they actually differ.

The extra operating time with remote approaches isn’t a flaw. It’s the price of working through a small, hidden entry point. If you want to see how these options fit into a full treatment plan, our thyroid cancer treatment page walks through them.

Most people only think of these questions after the decision is made, so it helps to have them ready beforehand. Dr. Nayak’s own technique, RABIT, goes in through the breast and armpit and has been used for removing thyroid tumours under about 4 cm, which is exactly the kind of detail worth asking any surgeon about their own method.

• Do my tumour size and scan findings actually allow a remote approach, or is open surgery the safer fit?
• How many of these specific surgeries do you do in a year? Volume matters more than the title here.
• Under what circumstances would you switch to open surgery during the operation?
• How long is the usual hospital stay, and what should the neck and shoulder feel like in the first few weeks?
• When are the follow-up scans and blood tests, and who explains the results?
• What is the total cost, including the facility, and what might change it?

Compared with traditional open inguinal lymphadenectomy, endoscopic surgery is associated with fewer wound-related complications. The open procedure requires a long incision in the groin and the creation of skin flaps, increasing the risk of infection, skin breakdown, and fluid collection. In contrast, endoscopic surgery uses small incisions in the thigh, helping preserve the skin over the groin and reduce wound complications. However, it is not suitable for every patient, and the choice of approach depends on the type of cancer, the extent of lymph node involvement, and the patient’s overall condition.

According to Prof. Dr. Sandeep Nayak, a surgical oncologist who has worked on modified endoscopic techniques for inguinal lymphadenectomy, “The groin is an unforgiving place to cut. The skin is thin over the nodes, it folds and it moves, and the open operation puts all of that at risk. Going in through small cuts on the thigh protects the skin. In the right patient, that one change removes many of the wound problems we used to accept. The cancer still has to be cleared completely, though. That comes first.”

The nodes sit just under a thin layer of skin, and open surgery has to lift that skin to reach them.

The skin flap: A large flap is raised off the nodes beneath. Its blood supply is disturbed, and the edges can die back.

The groin itself: Skin folds, moisture and constant hip movement make this a hard place for a wound to heal.

Lymph leakage: Cutting lymph channels lets fluid collect under the skin as a lymphocele or seroma.

Who needs it: Nodes are removed in penile cancer, vulvar cancer and melanoma of the leg when spread is present or likely.

In published open series, wound complications have been reported in roughly one in five to one in two patients. Our page on groin lymph node dissection explains who needs the operation and how it’s planned.

Wound infection: The clearest difference. Pooled studies show fewer infections after endoscopic surgery.

Skin necrosis: Fewer flap problems in several meta-analyses, since no large flap is raised. One recent review found no significant gap, so the picture isn’t uniform.

Lymph related problems: Lymphocele rates look similar between the two. Lymphedema is lower in some pooled results, not all.

Cancer control: Recurrence looks comparable in studies so far, but the evidence comes from small studies. Bulky nodes or skin involvement usually mean open surgery is still the safer choice.

Whether a ground-glass nodule in the lung requires monitoring or surgery depends mainly on its size, type, and changes over time. Small, stable nodules are usually monitored with repeat CT scans rather than treated immediately. However, part-solid nodules, or those that grow or develop a solid component, may require further evaluation and, in some cases, surgery. Since many ground-glass nodules are benign or may resolve on follow-up imaging, the decision to operate is based on their appearance, growth pattern, and overall risk rather than a single CT scan.

According to Prof. Dr. Sandeep Nayak, a surgical oncologist who advises on every ground glass nodule that arrives with a CT report, “A ground glass nodule on a report frightens people, and the fear is often bigger than the finding. Many fade or stay unchanged for years. The ones we act on are the ones that grow or develop a solid component. So the scan that matters most is often the repeat one, not the first. Watching is a decision, not a delay.”

Watching is the usual first step for small, stable nodules. It’s an active plan with fixed scan dates.

Under 6 mm: A single small nodule generally needs no routine follow up. Suspicious ones may get a check at two and four years.

Pure ground glass, 6 mm or more: A repeat CT at 6 to 12 months confirms it’s persistent. If it stays unchanged, scans continue every two years up to five years.

Part solid with a small solid portion: Repeat CT at 3 to 6 months. If nothing changes, yearly scans follow for five years.

Why repeat scans come first: Infection and inflammation can leave temporary ground glass areas. These often clear on their own.

These intervals are guidelines. Smoking history, family history or a past cancer can change the plan. Our page on lung cancer treatment covers how a nodule is assessed and treated.

Surgery enters the picture when a nodule starts behaving like an early cancer.

Growth: A nodule that enlarges across scans is treated as suspicious, even if it began small.

Solid component: A persistent part solid nodule with a solid portion of 6 mm or more is considered highly suspicious. A new or growing solid portion in a pure ground glass nodule is a similar warning.

Type of operation: Often a segmentectomy or wedge resection, which removes the nodule and saves more healthy lung than a lobectomy. Size, position and make up of the nodule decide it.

Finding it during surgery: Small ground glass nodules are hard to feel, so a wire or coil may be placed under CT guidance beforehand to mark the spot.

How much lung comes out is a common worry. Our blog on whether lung cancer surgery removes the whole lung answers it.
