A cancer where the food pipe meets the stomach can be removed in two ways. One works in the abdomen and the chest. The other works in the abdomen alone. The Siewert type decides which, and this page explains what the robot changes at the junction. Apollo Hospital, Bhat, Gandhinagar · Gota OPD, Ahmedabad.

Shah’s Gastro, Cancer & Robotic Surgery Centre. Two higher degrees in GI surgery and 18 years of experience in GI and cancer surgery. Every junction cancer goes to the tumour board before treatment. Dr Harsh Shah performs the operation himself.
In short
The Siewert type is set by where the tumour’s centre lies. It is measured at endoscopy, from the line where the food pipe meets the stomach.
Types I and II are treated as food pipe cancers. They need an oesophagectomy, with work in the abdomen first and then in the right chest.
Type III is treated as a stomach cancer. It needs a total gastrectomy with the lower food pipe, done through the abdomen alone.
The junction is a short zone. Tumours just above it, across it and just below it behave differently. So they are sorted into three types.
| Type | Where the centre lies | Treated as | The operation | Where the surgeon works |
|---|---|---|---|---|
| Siewert I. | In the lower food pipe, one to five centimetres above the junction. | A food pipe cancer. | Oesophagectomy with the join in the chest. | Abdomen, then right chest. |
| Siewert II. | Across the junction, from one centimetre above to two below. | A food pipe cancer, in our protocol. | Oesophagectomy, preferred over a larger stomach operation. | Abdomen, then right chest. |
| Siewert III. | Below the junction, in the top of the stomach. | A stomach cancer. | Total gastrectomy with the lower food pipe. | Abdomen only, reaching up through the diaphragm. |
Type II is the type most often debated. Some centres remove the whole stomach and the lower food pipe for selected type II tumours. Our protocol prefers an oesophagectomy for type II. The tumour board discusses each case.
The type is read from the endoscopy and the CT together. The surgeon’s own endoscopy is often the most useful, because it shows the edges of the tumour in relation to the junction.
Once your type is set, one operation follows. Each one has its own page. This page explains what changes at the junction itself.
| Your situation | The operation | Read next |
|---|---|---|
| Siewert I or II, after treatment before surgery. | Robotic oesophagectomy, abdomen and chest. | Robotic oesophagectomy, phase by phase |
| Siewert III. | Total gastrectomy, with the lower food pipe. | Robotic total gastrectomy |
| A cancer higher up the food pipe. | Oesophagectomy, often with the join in the neck. | Robotic food pipe cancer surgery |
| Not yet sure of your type, or which treatment comes first. | The full test and treatment plan. | Junction cancer treatment steps |
Most junction cancers are adenocarcinomas. They usually get four cycles of chemotherapy before the operation and four after. Squamous cancers get chemoradiation first instead.
The chemotherapy for adenocarcinoma is a four-drug plan given every two weeks. The operation follows four to six weeks after the last cycle. Chemoradiation is used when this plan does not suit you.
For a type II tumour, a short look inside with a camera often comes first. It checks the lining of the abdomen for small spots that a scan can miss. If spots are found, the plan changes.
Swallowing can fail during chemotherapy. When surgery is planned, a thin feeding tube into the small bowel is preferred to a stent. Food keeps you strong enough to finish treatment.
The junction sits deep under the ribs, in front of the aorta. Wristed robotic instruments reach up through the diaphragm opening with a steady, magnified view.
Our protocol prefers keyhole or robotic surgery for an oesophagectomy, where the team has the experience. Compared with open surgery, these approaches cause fewer chest infections. The robot’s wristed tips add reach in tight spaces.
In the abdomen, the stomach is freed and shaped into a tube that will replace the food pipe. Its main blood supply, along the greater curve, is kept with care. The left gastric vessels are tied at their root, with their nodes.
Then the surgeon works up through the diaphragm. The lower food pipe is freed from the aorta and the lining of the lungs. This is where the wristed tools help most, because straight tools lose their angle under the ribs.
In the chest, for types I and II, the food pipe is freed from the level of a large vein called the azygos down to the diaphragm. Nodes along it come out with it. The stomach tube is pulled up and joined to the food pipe just below that vein.
A dye given into a vein glows under the robot’s camera. It shows whether the top of the stomach tube has a good blood supply. If the tip looks pale, it is trimmed back until it glows evenly.
The hiatus is the opening in the diaphragm for the food pipe. For a junction cancer it is opened wide, so the lower food pipe and nodes come out together.
The two muscle pillars of the hiatus are identified first. The front of the opening is then divided. The surgeon works upward into the lower chest, keeping close to the tumour’s outer edge.
The thin lining over the lung is sometimes opened on purpose. That is accepted when it keeps the dissection in the right plane. A chest drain manages it afterwards.
At the end, the hiatus is closed loosely around the new stomach tube. One finger’s gap is left so its blood supply is not squeezed. The tube is stitched to the muscle pillar so it cannot twist or slip.
For a type III tumour, the hiatus is opened the same way from the abdomen. Nodes along the lower food pipe are removed from below. A large hiatus hernia beside the tumour is repaired in the same operation.
The cut on the food pipe must be well clear of the tumour. A sample is checked under the microscope during the operation. The plan changes if cancer is found.
For adenocarcinoma, our protocol aims for at least five centimetres of normal food pipe above the tumour, as seen by the surgeon. A clip or ink mark placed at endoscopy can help find the upper edge.
Junction cancers spread first to nodes around the top of the stomach and the lower food pipe. The operation clears these with the tumour, in one piece.
| Type | Node fields cleared |
|---|---|
| Siewert I and II. | Two fields: the upper abdomen around the left gastric vessels, and the chest along the food pipe. Neck nodes are not removed as a routine. |
| Siewert III. | The full set of stomach nodes, called D2, plus nodes along the lower food pipe reached through the hiatus. The spleen is kept unless the cancer involves it. |
The pathologist counts the nodes. Our protocol sets a minimum number, because too few nodes can hide spread. The count and the margins appear in your report.
The robot is not chosen for every junction cancer. Bulky tumours, heavy scarring after chemoradiation and some past chest operations call for open or hybrid surgery.
| Situation | Usual plan |
|---|---|
| A bulky tumour, or dense scarring after chemoradiation. | Open, by the surgeon’s judgement. |
| A past right chest operation with the lung stuck down. | Keyhole abdomen with open chest, or a plan that avoids the chest. |
| Weak lungs on breathing tests. | Breathing training first. Sometimes a plan that avoids the chest. |
| A heavy build. | The robot often helps, because it reaches the hiatus well. |
| A large type III tumour, or one grown through the stomach wall. | Open, as for a bulky stomach cancer. |
| Spread to the liver or the lining of the abdomen. | No operation. Treatment by drugs. |
| Too unwell for a major operation. | A gentler plan, or comfort care first. |
For type III, our stomach cancer protocol keeps keyhole and robotic surgery mainly for lower stomach tumours. For a total gastrectomy, open or robotic is the surgeon’s call on your case.
All three remove the same tissue and the same nodes. They differ in the cuts, the view in tight spaces, chest infections, and how soon you recover.
| Open | Keyhole | Robotic | |
|---|---|---|---|
| Cuts. | A long cut on the abdomen and one on the chest. | Small ports. | Small ports. |
| View at the hiatus. | Direct, but deep. | Magnified, flat. | Magnified, 3D, steady. |
| Tools. | Hands and long tools. | Straight. | Wristed. |
| Chest infections. | More. | Fewer. | Fewer. |
| Pain. | More. | Less. | Less. |
| Nodes removed. | The same. | The same. | The same. |
| Hospital stay and return to work. | Longest. | Shorter. | Shorter. |
| Cost. | Lowest. | Close to open. | Higher, for robotic tools. |
The figures for complications and stay that apply to your own operation are given at the consent visit.
You sit out of bed on the evening of surgery. Feeding starts through a small tube into the bowel the next day. Sips by mouth start a few days later.
| When | What happens |
|---|---|
| Day of surgery. | Breathing tube out early. Head raised. Sitting out of bed. Breathing exercises start. |
| Next day. | Walking two or three times. Slow feeds through the feeding tube. Chest physiotherapy. |
| Second and third days. | Feeds increased. Walking four times. Drip reduced. Stomach tube out when drainage is low. |
| Fourth and fifth days. | A water trial by mouth, sometimes after a check X-ray. Then sips and liquids. |
| Sixth to eighth days. | Soft diet. Chest drain out. Discharge checks. |
The team acts the same day on warning signs. A fast pulse or a new irregular heartbeat. Fever. Rising need for oxygen. Cloudy or bile-coloured fluid in a drain. Any of these may mean a leak and is checked at once.
After a type III total gastrectomy, the early days follow the same pattern of walking and breathing exercises. Your own plan is written for the operation you have.
After either operation, meals become small and frequent for life. Sleeping with the head raised helps with reflux. Some people need the join stretched later.
You go home able to drink and eat soft food, or with feeds through the tube. A family member is trained in tube care. A dietitian gives a written plan.
Food can rush through quickly at first. This can cause weakness or dizziness after meals. Smaller meals with less sugar help.
Without a stomach, vitamin B12 is not absorbed. B12 injections are given every three months for life after a total gastrectomy. Iron and B12 are checked after an oesophagectomy too.
If food starts to stick weeks or months later, the join may have narrowed. A simple stretch through an endoscope usually fixes it. It may need repeating.
The tissue report is discussed at two weeks. It decides what follows: more chemotherapy, immunotherapy for a year, or careful watching. Visits continue for ten years.
| Situation or time | What follows |
|---|---|
| Adenocarcinoma after the four-drug plan. | The four cycles after surgery are completed. |
| Cancer left in the specimen after chemoradiation. | Immunotherapy for one year, starting within four to sixteen weeks. |
| No cancer left after chemoradiation. | No further drugs. Follow-up only. |
| Every three months for ten years. | Symptoms, weight, swallowing and fitness. |
| Scans. | CT of chest and abdomen every six months for two years. Then yearly to 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: a stomach cancer patient’s family, and two patients of Dr Harsh Shah treated for other cancers. No review on these listings yet names the food pipe. Below them, a patient speaks after robotic surgery for food pipe cancer.
Watch Dr Harsh Shah’s step-by-step video of a robotic oesophagectomy for food pipe cancer (YouTube).
A robotic operation at the junction costs more than an open one, because of the robotic tools. A neck join, a longer stay or a complication changes the total.
The office prepares a written estimate once the operation is decided. Cashless admission is arranged at Apollo Hospital, Bhat when your policy allows it. Allow a day or two for robotic approval. Ask whether your policy covers robotic surgery, and up to what limit. Bring the policy papers, photo identity, all reports with scans on disc, and your medicine list.
Where the centre of the tumour lies, measured at endoscopy from the junction line. The CT helps confirm it.
For types I and II, the chest part is done through small robotic ports on the right side. For type III, the operation stays in the abdomen.
Our protocol prefers an oesophagectomy for type II. Some centres remove the whole stomach for selected type II tumours. The tumour board decides for each patient.
Sometimes. Our stomach protocol uses keyhole or robotic surgery mainly for lower tumours. For a total gastrectomy the surgeon decides, and bulky tumours are operated open.
More food pipe is removed in the same operation. If the clear level is too high for a chest join, the join is made in the neck.
You eat most foods, but in small, frequent meals for life. Sleeping with the head raised helps with reflux.
