Shah’s Gastro, Cancer & Robotic Surgery Centre. Two higher degrees in GI surgery and 18 years of experience in GI and cancer surgery, including cytoreductive surgery with HIPEC and robotic GI cancer surgery. Every case of spread to the abdominal lining goes to the tumour board. Dr Harsh Shah performs the keyhole look and the operation himself.
In short
For cancer on the lining of the abdomen, keyhole surgery has one clear job. It lets the surgeon look inside, score the disease and take tissue.
The main operation, cytoreductive surgery, is planned as an open operation in our protocol. Heated chemotherapy, when advised, is given during that same operation.
The robot may still be used for the cancer it started from. That applies when the tests show no spread to the lining of the abdomen.
Robotic surgery means small cuts and a quicker recovery for many cancers. So families hope for the same when the lining of the abdomen is involved.
This centre does robotic surgery for many GI cancers. Even so, our protocol for peritoneal disease does not list a robotic route for the main operation. Below, each step is set out with the way it is done.
| Step | How it is done | Approach |
|---|---|---|
| Tissue to confirm the diagnosis. | A guided needle, or samples taken at a keyhole look. | Needle or keyhole. |
| Scoring how much disease there is. | A keyhole look, called diagnostic laparoscopy. | Keyhole. |
| Removing every visible spot of disease. | Cytoreductive surgery. | Open. |
| Heated chemotherapy inside the abdomen, when advised. | HIPEC, given in the same operation by an open or closed method. | Open. |
| Fluid that keeps coming back, with no operation planned. | Drainage with a needle, or a thin tunnelled tube. | No operation. |
| The first cancer, when there is no spread to the lining. | That cancer’s own plan. | Robotic may suit. |
Scans can miss small spots on the lining, mainly on the small bowel. A keyhole look lets the surgeon see them directly, before any big decision is made.
The look is done under general anaesthesia. A camera goes in through a small cut. One or two more small cuts let the surgeon move the bowel gently and take samples. Our protocol uses this look before anyone is committed to the main operation, whenever complete removal is in doubt.
The surgeon works through the abdomen in a fixed order. Nothing is removed at this stage except samples.
The look gives a score called the Peritoneal Cancer Index. The abdomen is split into thirteen areas, and each one is scored from nought to three by spot size.
Two things then shape the plan. One is this score. The other is the type of cancer, and the type matters more than the number. For example, slow-growing mucinous disease from the appendix can benefit even when the score is high. Stomach cancer needs a very low score before surgery is considered.
| What the look shows | What usually follows |
|---|---|
| All the disease looks removable. | The open operation is planned, after some weeks of preparation. |
| A coating over much of the small bowel, or a shrunken bowel fan. | The abdomen is not opened. Treatment with medicines is planned. |
| Spread outside the lining, for example in the liver or lungs. | The main operation is generally not advised. |
| The tissue shows tuberculosis, not cancer. | Tuberculosis treatment. No cancer operation. |
| Stomach cancer with more than very limited spread. | Medicines first. Surgery only in a trial or specialist plan. |
Cytoreductive surgery is not one procedure. It is a set of procedures, chosen during the operation, to remove every visible spot of disease.
Disease can sit in any of the thirteen areas. All of it must be cleared in one sitting. Our protocol plans this work as an open operation, and it does not list the robot for it.
If complete removal turns out not to be possible, the operation is stopped. An incomplete operation brings the harm without the benefit. You are told about this possibility before you sign.
HIPEC is warm chemotherapy washed through the abdomen after the disease is removed. In our protocol it is given during the open operation, by an open or closed method.
The drug depends on where the cancer started. Mitomycin-C is used for appendix and bowel cancer. Cisplatin is used for ovarian cancer and mesothelioma. A named perfusionist runs the machine, and strict rules protect the theatre staff.
HIPEC is not added to every operation. For bowel cancer, a large trial found no gain in survival from one HIPEC drug added to complete surgery, and more complications. If HIPEC is proposed for bowel cancer, this is explained before you consent.
A robotic comparison usually covers blood loss, lymph nodes, stay and return to work. For peritoneal disease, the measure that matters most is different: was every visible spot removed?
| Question | Keyhole look | Open cytoreduction | Robot |
|---|---|---|---|
| What is it used for? | Scoring, tissue and the decision. | Removing all visible disease, with HIPEC if advised. | Not listed in our protocol for either step. |
| Cuts. | A few small cuts. | A long cut down the middle of the abdomen. | Not used for this. |
| Blood loss. | Small. | Can be large. Blood is cross-matched in advance. | Not used for this. |
| Lymph nodes. | Not the aim. | Not the main measure. The completeness score is. | Not used for this. |
| Hospital stay. | Usually short. | Intensive care first. Discharge usually in the second week, later with a complication. | Not used for this. |
| Return to daily life. | Soon after the small cuts heal. | Slow. Tiredness can last for months. | Not used for this. |
Your own figures for blood loss, stay and risk are given at the consent discussion, over more than one visit.
When scans and the keyhole look show no spread on the lining, the cancer is treated by the plan for where it started. That operation may suit the robot.
For example, a bowel or stomach cancer without spread follows its own protocol. Whether that operation is robotic, keyhole or open is decided for that cancer. The GI cancer pages on this site explain those operations.
One thing is not done at that operation. Heated chemotherapy is not added just in case for high-risk bowel cancer. Two trials showed no benefit from that, so it is not offered. Follow-up with a low threshold for a keyhole look is used instead.
For this operation, preparation changes how well people come through it. It starts at the first visit and usually takes some weeks.
| What is done | Why |
|---|---|
| Exercise and breathing training. | It builds strength for a long operation. |
| Nutrition support. | It helps healing and the slow return of bowel function. |
| Correcting a low blood count, low albumin and high sugar. | It lowers the chance of problems. |
| Stopping smoking and alcohol at least four weeks before. | It helps the lungs and the wounds. |
| Marking a stoma site with the stoma nurse. | It is done in every case, in case a bag is needed. |
| Booking intensive care and blood in advance. | Both are planned before the day. |
| Consent over more than one visit. | It is never taken on the day of surgery. |
The keyhole look usually means a short stay. The open operation means intensive care first, then a slower recovery that is planned that way on purpose.
| When | After the open operation |
|---|---|
| Day of surgery. | Intensive care. Urine is checked every hour. Pain relief comes from several medicines together. |
| First days. | Daily blood tests. Gentle walking. A step down from intensive care once stable. |
| Rest of the first week. | Food starts as the bowel wakes up. Drains are checked every day. Stoma teaching if needed. |
| Second week. | The white cell count usually reaches its lowest point and recovers. Discharge often falls here. |
Some signs are never watched overnight. A fever or a fast pulse. Less urine than before. Drain fluid that turns cloudy or looks like bowel content. The team acts on any of these the same day.
Follow-up starts two weeks after discharge, with the tissue report and the completeness score. Scans and blood markers then follow a written schedule.
| When | What is checked |
|---|---|
| Two weeks. | Wound and stoma. The report and the completeness score are explained. Referral for chemotherapy. |
| First two years. | Every three months: symptoms, weight, fitness and tumour markers. A CT scan every three to six months. |
| Years three to five. | Every six months. MRI when the CT is unclear about small spots. |
| Slow-growing pseudomyxoma. | Checks go on well beyond five years. |

“I had a truly positive experience with Dr. Harsh Shah. He is not only highly knowledgeable but also very compassionate and patient in explaining every detail. I underwent CRS HIPEC surgery under his care, and I couldn’t have asked for a better doctor. The entire process was smooth, and his expertise made a complex procedure feel manageable. Post-surgery recovery was well-monitored, and he was always available for any concerns. Highly recommend Dr. Harsh Shah for anyone needing advanced surgical oncology care.”

Quoted exactly as written on the centre’s Google listings. The first patient had cytoreductive surgery with HIPEC under Dr Harsh Shah. The other two were treated for other GI cancers.
A keyhole look alone costs less than the main operation. The open operation’s cost depends on its extent, HIPEC, and days in intensive care.
The office prepares a written estimate once the plan is decided. Cashless admission is arranged at Apollo Hospital, Bhat when your policy allows it. Bring the policy papers, photo identity, all reports with scans on disc, and your medicine list.
Our protocol plans it as an open operation. The robot is not listed for this step.
It scores the disease directly and shows whether complete removal is possible. If it is not, you are spared a large operation.
It is done under general anaesthesia through small cuts. The stay is usually short.
It depends on where the cancer started. For bowel cancer the evidence is limited, and you are told this before you consent.
The operation is stopped. Treatment continues with medicines and supportive care.
If there is no spread to the lining, the bowel cancer follows its own plan. That operation may be robotic.
