Laparoscopic and robotic gastrectomy: what changes and what does not | CION Cancer Clinics
A laparoscopic gastrectomy removes the same amount of stomach and the same lymph nodes as an open operation, through four or five small cuts instead of one long one. Robotic surgery is keyhole surgery with a different set of tools. Smaller cuts usually mean less wound pain and a shorter stay. They do not change what is removed. This page explains who keyhole suits, who it does not, and what to ask your surgeon. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Is keyhole gastrectomy the same cancer operation as open surgery?
Yes. A laparoscopic gastrectomy removes the same amount of stomach and the same lymph nodes as an open operation. What changes is the way in: several small cuts and a camera instead of one long cut down the middle of the abdomen.
What keyhole actually means
The abdomen is filled with gas to make room. Through four or five small openings the surgeon passes a camera and long thin instruments, and works while watching a screen. The stomach, or part of it, is freed and the nodes are cleared in the same way as in open surgery.
Where the robot fits
Robotic gastrectomy is keyhole surgery with a different set of tools. The surgeon sits at a console a few feet away and moves instruments that bend at the wrist and steady the hand. The robot does nothing on its own. It is a way of holding the instruments, not a different operation, and the cuts on your abdomen look much the same as ordinary keyhole.
Why families ask about it
Smaller cuts usually mean less pain in the first days and a shorter stay. Those are real gains. They do not change what is removed or the cancer result, which depends on the stage and the pathology report.
The technique your surgeon offers depends on your cancer, your body and their own training. Ask what they recommend for you and why, rather than asking for a technique by name.Side by side
Open and keyhole gastrectomy, compared
Open gastrectomy
Keyhole or robotic gastrectomy
One long cut from below the breastbone towards the navel
Four or five small cuts, one widened to remove the stomach
Surgeon sees and feels the tissue directly
Surgeon works from a magnified screen image
Same stomach and same lymph nodes removed
Same stomach and same lymph nodes removed
Usually more wound pain in the first days and a longer stay
Usually less wound pain, earlier walking and eating, shorter stay
Preferred for large tumours, tumours stuck to nearby organs, or after earlier abdominal surgery
Preferred for earlier, contained tumours where the surgeon is experienced in the technique
Not sure whether this applies to you?
Ask an oncologistThe decision
What decides whether keyhole is offered to you?
The choice is made on your scans, your body and your surgeon's experience. It is not a matter of which option is newer.
How far the cancer has grown
A tumour confined to the stomach wall suits keyhole well. One that has grown into the pancreas, spleen or bowel usually needs the direct view and the hands of open surgery.
Chemotherapy before surgery
Many stomach cancers in India are treated with chemotherapy first to shrink them. That can make the tissues stiffer and harder to handle with long instruments, and some surgeons prefer open surgery after it.
Earlier operations and body build
Scar tissue from a previous abdominal operation, a very heavy build, or a heart or lung condition that makes the gas hard to tolerate can all tip the choice towards open surgery.
Your surgeon's experience
Keyhole gastrectomy with a full node clearance is a skill built over many cases. A surgeon who does it often will offer it where it fits. A surgeon who does not will say so, and open surgery in experienced hands is a sound choice.
In theatre
What actually happens during a keyhole gastrectomy
Going to sleep
A full general anaesthetic, the same as for open surgery. A tube into the bladder and often a small tube through the nose are placed while you are asleep.
The gas and the ports
Carbon dioxide gas lifts the abdominal wall away from the organs. Small openings called ports are made for the camera and instruments.
Freeing the stomach and clearing the nodes
The blood vessels to the stomach are sealed and divided, and the lymph nodes along them are removed in one block. This is the longest part and the part that matters most for the cancer.
Removing the tissue and joining the bowel
One cut is widened so the stomach can be lifted out in a bag. The bowel is then joined to what remains, or to the gullet, with staplers or stitches.
If it has to become open surgery
Sometimes bleeding, dense scarring or an unexpected finding means the safest course is to make a larger cut and finish the operation open. That is a judgement made for your safety, not a failure.

Commonly believed
Four things families tell us, and what is actually true
"Keyhole means a smaller operation."
The cuts are smaller. The operation inside is the same size. The same stomach and the same lymph nodes come out, and the same joins are made. Recovery of the wound is easier; recovery of eating follows the same path.
"The robot does the surgery."
The surgeon does every part of it. The robot holds and steadies the instruments and follows the surgeon's hands. Nothing is automated, and the surgeon's experience matters exactly as much as it does at the table.
"Keyhole surgeons remove fewer lymph nodes."
In experienced hands the node clearance is the same, and the pathology report will state how many nodes were found. If a full clearance is not possible by keyhole in your case, the surgeon should say so and convert to open surgery.
"After keyhole she will be back to normal in a week."
She may be home within about a week and walking well. Eating, energy and weight take months to settle whichever way the stomach was removed, because that part of recovery is about living without a stomach, not about the cuts.
At your centre
What to ask about laparoscopic gastrectomy in India
Keyhole and robotic gastrectomy are available at several cancer centres in India, including in Hyderabad, but not every surgeon offers them and not every patient is suited. The right question is not whether a centre has the machine but whether the surgeon in front of you does this operation regularly and would choose it for your cancer.
Questions worth asking
Ask which approach the surgeon recommends for you and why. Ask how often they perform keyhole gastrectomy with a full node clearance, and how often they have had to convert to open surgery. Ask what the cost difference is, because robotic surgery usually carries an extra charge for the instruments, and whether your scheme or insurer covers that difference.
What CION can and cannot promise
CION cannot tell you on this page which technique you will be offered. That is decided by the surgical oncologist after seeing your scans and examining you, and it is discussed at a tumour board first. Call the helpline with your reports and we will help you reach the right surgeon.
Being straight with you
What this page cannot tell you
This page cannot tell you whether keyhole surgery is safe for your cancer, or whether it would change your result. The technique is a means of getting in. What decides the outcome is the stage of the cancer, the completeness of the node clearance and the chemotherapy given before or after.
Who keyhole does not suit
People whose tumour has grown into nearby organs, people with heavy scarring from earlier surgery, people who cannot safely tolerate the gas because of a heart or lung condition, and people whose surgeon does not perform the technique often enough to be confident in it. In each case open surgery is the sound choice, not a lesser one.
Bring your endoscopy report, your CT or PET-CT and any chemotherapy notes to the first appointment. Those decide the approach, not a preference.Questions we are asked
Common questions about keyhole and robotic gastrectomy
Is keyhole surgery as safe for cancer as open surgery?
For suitable patients in experienced hands, the cancer operation is the same and the amount of tissue removed is the same. The safety question is really about fit: the right patient, the right tumour and a surgeon who does the operation often.
Will I go home sooner after keyhole?
Usually, by a few days, because there is less wound pain and walking and eating start earlier. The stay still depends on how quickly the bowel wakes up and whether there are any problems at the join. Your surgeon will give you a likely range for your own case.
Does robotic surgery give a better result than laparoscopic?
The robot offers the surgeon steadier hands and instruments that bend, which some find useful for the node clearance and the joins. For the patient, the cuts, the stay and the cancer result are broadly similar to laparoscopic surgery. The surgeon's experience matters more than the tool.
What if the surgeon has to switch to open surgery?
It happens, and it is planned for. If bleeding, scarring or an unexpected finding makes keyhole unsafe, a larger cut is made and the operation is finished open. You will wake with a longer wound and recover as an open patient would. It is a safety decision, not a mistake.
Does keyhole cost more?
Laparoscopic gastrectomy is often priced close to open surgery, with the shorter stay offsetting the instrument cost. Robotic surgery usually carries an extra charge for the instruments. Ask for an itemised estimate and check whether Aarogyasri, CGHS, ECHS, EHS or your insurer covers the difference before you decide.
Can keyhole be done after chemotherapy?
Often, yes. Chemotherapy before surgery can make the tissues stiffer and the planes harder to see, so some surgeons prefer open surgery in that setting and others are comfortable with keyhole. It is one of the things the surgeon weighs when looking at your scans after chemotherapy.
Will the scars be visible?
There will be several small scars and one slightly longer one where the stomach was lifted out. They fade over months. The scar is the least important thing about this operation and should not decide the approach.
Is keyhole gastrectomy done at CION?
The approach offered depends on the surgical oncologist who sees you and on your cancer. Rather than promising a technique on a web page, we would ask you to bring your reports so the surgeon can tell you what suits you and why. Call the helpline and we will arrange that conversation.
