Shah's Gastro, Cancer & Robotic Surgery Centre · Ahmedabad & Gandhinagar
How far the tumour sits from the anal opening changes almost everything that follows. Apollo Hospital, Bhat · Gota OPD, Ahmedabad.
Every rectal cancer carries a measurement: the distance from the anal opening to the lower edge of the tumour. That number decides which operation is possible, whether radiotherapy is in the plan, and whether a stoma is discussed at all. When the tumour sits high the answers are usually the gentler ones — an anterior resection with the bowel rejoined, commonly without a stoma, often without pelvic radiotherapy. Dr Harsh Shah’s position is that a patient is entitled to know who measured that number, on what instrument, and which board agreed the plan built on it.
Shah’s Gastro, Cancer & Robotic Surgery Centre. For surgical purposes the rectum is not one organ. It behaves as three different problems depending on how high the tumour sits, and the operation, the need for radiotherapy and the stoma question differ in each. A tumour recorded at the wrong height is planned as the wrong disease — an error made on paper, in a clinic room, long before theatre.

A tumour in the upper rectum — furthest from the anal opening, above the fold of the peritoneum — is usually treated by anterior resection with the two ends of bowel joined, the sphincter never in question, and usually no stoma. The same cancer sitting low is a materially different operation, and a materially different conversation.
A patient told only “you have rectal cancer” has not yet been told the thing that matters most. The useful question at the first consultation is not how serious it is, but how high it is, and who measured it.
Three examinations contribute to that number, and only one is reliable alone.
The first is a digital rectal examination — unglamorous, and mandatory at first contact, because a finger finds a low rectal tumour more dependably than any scan and records whether the growth can be reached, whether it moves freely, and whether it sits against the sphincter. Rectal bleeding should never be blamed on piles without it.
The second is the distance recorded at endoscopy, and it carries a trap. It must be measured on a rigid scope: a flexible colonoscope over-estimates distance because it follows a curve rather than a straight line. A tumour reported higher than it truly is gets planned as the wrong operation, and the error travels quietly through every later decision.
The third, and the pivotal one, is the pelvic MRI.
No treatment decision for a rectal cancer should be taken before a pelvic MRI exists and has been read by the team that will treat you. A plan offered on a CT scan alone, or on the colonoscopy report alone, is a plan built on the wrong picture.
A report saying “rectal mass, further correlation advised” has not helped anyone. What is needed is a synoptic report naming the same six things every time.
| What the report must state | Why it changes your plan |
|---|---|
| T stage — how deep the tumour has grown | Separates an early cancer that can go straight to surgery from one that needs treatment first |
| Distance to the mesorectal fascia (mrCRM) | A threatened or involved margin means radiotherapy-containing treatment before surgery, never less |
| Extramural venous invasion (EMVI) | Present, it moves the case into the high-risk group even when everything else looks modest |
| Nodal status in the mesorectum | Contributes to the risk group and to the chemotherapy discussion |
| Height from the anal verge | Decides which operation is on the table at all |
| Sphincter and levator involvement, for low tumours | The sentence that decides stoma or no stoma |
If your MRI report does not contain those six items, ask for it to be reported again rather than accepting a plan built on it. A structured re-read costs days. Discovering the gap after an operation costs considerably more.
Alongside the MRI, a contrast CT of chest, abdomen and pelvis looks for disease elsewhere, a full colonoscopy excludes a second tumour higher in the bowel, and a baseline CEA is taken so later changes mean something. Mismatch-repair testing is done on every rectal cancer: a small group respond to immunotherapy in a way that changes the entire plan.
Once the MRI is read, a rectal cancer falls into one of three groups. The group, not a surgeon’s preference, sets the order of treatment.
| Group | What it means | What is done |
|---|---|---|
| Early / favourable | An early tumour, or a moderately deep one high in the rectum with a clear margin on MRI and no venous invasion | Straight to surgery. No treatment beforehand |
| Intermediate | A deeper tumour whose margin on MRI is not threatened | Chemotherapy alone before surgery, with pelvic radiotherapy deliberately left out and held in reserve |
| Locally advanced | A tumour growing into neighbouring structures, a threatened or involved margin, venous invasion, bulky nodes, or a low tumour | All the chemotherapy and the radiotherapy first, then surgery |
A high tumour with a clear margin on MRI and no venous invasion most often belongs in the first group — surgery without months of treatment beforehand. That is the practical reward for a tumour being high, and it is decided on the report, not on the day.
A highly selected very early tumour is sometimes removed through the anus itself, without opening the abdomen, and converted to a full operation only if the pathology proves unfavourable. That route is narrow and its criteria are strict.
For an upper rectal tumour the operation is an anterior resection, with the two cut ends of bowel joined. Three features make it gentler than its low counterpart.
First, how much of the fatty envelope around the rectum is taken. In a low tumour it is stripped entirely, to the pelvic floor; for a high tumour it is divided a short distance below the tumour, leaving the lower rectum and its nerves undisturbed. Less dissection deep in the pelvis means less disturbance to bladder and sexual function.
Second, where the join sits: high in the pelvis rather than deep at the pelvic floor, and a high join is more forgiving.
Third, what it is judged by. The envelope must come out intact and the clearance between tumour and its cut edge must be adequate; the pathologist grades both, and those grades — not the size of the incision — are the measure of the operation. A surgeon losing the correct plane converts to open surgery without hesitation, because the specimen is the endpoint.
The approach may be laparoscopic, robotic or open. Robotic instruments have a real advantage deep in a narrow pelvis, which matters most in a low tumour and matters less in a high one. No approach changes the standard: an intact envelope and a clear margin.
One situation overrides all of this. A rectal tumour obstructing the bowel is not an emergency cancer operation: the correct first move is a defunctioning stoma, then staging, then treatment, then the cancer operation in planned conditions. Removing an unstaged obstructing rectal cancer as an emergency is an oncological error, not a rescue.
This is the fear that arrives before the diagnosis is understood, and for a high tumour it is usually answered early, and in the negative.
A temporary ileostomy is standard when the join lies low in the pelvis or at the anus: it does not prevent a leak but turns a dangerous one into a manageable one. A high join does not ordinarily need one. A permanent colostomy belongs to tumours involving the sphincter muscle, which an upper rectal cancer does not.
A patient is entitled to have this settled before theatre rather than discovered afterwards. Where any operation could produce a stoma, the stoma nurse marks the site beforehand and the teaching is given to the family in advance — not because a stoma is expected, but because a plan depending on good luck is not a plan.
Pelvic radiotherapy is effective and it is not free: its costs are felt long afterwards in bowel habit, sexual and urinary function, and fertility. Where it can be safely omitted, omitting it is a gain and not a compromise — and a high tumour with a clear margin is the commonest situation in which that is possible.
Where the margin on MRI is comfortably clear, chemotherapy alone before surgery is accepted and pelvic radiotherapy is held back. Where the tumour is close to or involving that margin, radiotherapy-containing treatment is given first and no version of the plan leaves it out.
The safeguard matters as much as the decision. Every decision to omit radiotherapy is taken at the tumour board, never by one doctor alone — surgeon, medical oncologist, radiation oncologist, radiologist and pathologist in one room. Board discussion is mandatory for every rectal cancer here before any treatment is offered: stricter than the rule for colon cancer, deliberately.
One item is time-critical and routinely forgotten: anyone of reproductive age must have fertility preservation discussed before pelvic radiotherapy begins. If radiotherapy is proposed and nobody has raised it, raise it yourself.
Where radiotherapy is given, surgery follows some two to three months after it ends. Operating into a recently irradiated pelvis is harder and heals worse; that interval is a clinical decision, not a delay.

A rectal cancer plan is reviewed at fixed points rather than decided once. It is revisited after any treatment given before surgery, when the scan and examination are repeated to see how the tumour responded, and again on the pathology report afterwards, which decides whether further chemotherapy is advised.
For a tumour high in the rectum, four situations make a second opinion worth the trouble.
When a stoma is proposed and nobody has explained why a high join could not be made. When radiotherapy is advised and nobody has shown you the margin on the MRI that justifies it. When an operation is offered and nobody has told you the case went to a tumour board. And when an obstructing tumour is treated as an emergency resection rather than stoma first, staging second, cancer operation third.
A second opinion frequently confirms the plan already made — not a wasted journey, but the same plan in writing before a major operation.
Ordinary questions — and a surgeon who welcomes them is telling you something useful.
How far is my tumour from the anal opening, and was that measured on a rigid scope? · Does my MRI report state the margin, the venous invasion, the height and the nodes? · Which risk group am I in, and why? · Was my case discussed at a tumour board, and what did it recommend? · Is radiotherapy planned — and if it is being left out, on what grounds? · Will the bowel be rejoined, and will I need a stoma? · If a stoma is possible, has the site been marked and the teaching arranged? · Has fertility preservation been discussed, before any radiotherapy? · Who will actually operate, and if the operation is robotic, who is at the console? · Who do I call at night in the first week after discharge?
Every complication is named in full before consent, in Gujarati, Hindi or English as you prefer: a leak at the join, infection in the pelvis, injury to the ureter, difficulty passing urine, changes in sexual function, later narrowing of the join, hernia at the wound, and the risk to life itself. How likely each is depends on where the join sits, whether radiotherapy was given, your age and your fitness — which is why those numbers belong across a desk, in your own case, not on a web page.
Before any planned resection the bowel is prepared with both a mechanical preparation and oral antibiotics, anaemia is corrected beforehand rather than transfused around the operation, and blood-thinning prophylaxis continues four weeks after pelvic cancer surgery rather than stopping at discharge.
One. Book your consultation. Bring the colonoscopy and biopsy reports, the slides, and the pelvic MRI on a disc rather than as a printout.
Two. The workup — examination recorded properly, height confirmed, a structured MRI read, staging CT, bloods and mismatch-repair testing.
Three. Your case goes to the tumour board, and a written plan comes back with the order of treatment set out and the radiotherapy and stoma questions answered.
Four. Surgery at Apollo Hospital, Bhat, the recovery pathway explained to your family beforehand — sitting out of bed and drinking on the day of operation, not a week later.
Five. Histology review at about two weeks, the decision on further chemotherapy, and a five-year surveillance schedule given to you in writing.
There is no single figure for rectal cancer treatment, and any page offering one is guessing. What moves it is the length of stay, the room category, whether chemotherapy and radiotherapy are in the plan, the approach used, and intensive care if needed. A high tumour treated with surgery alone and no stoma is a shorter pathway than a low one — another reason the height matters to a family.
The office prepares a written estimate before admission, so you are comparing a document rather than a conversation. Cashless admission is arranged where your policy allows it, and the pre-authorisation paperwork is prepared for you. Ask what the estimate excludes and who your point of contact is if the hospital and the insurer disagree.
Usually not. A join made high in the pelvis does not ordinarily need a temporary ileostomy, and a permanent colostomy belongs to tumours involving the sphincter muscle, which a high tumour does not. The answer comes from your MRI before the operation, not during it.
Because the margin on the MRI differs between you, and probably the height too. Where that margin is comfortably clear, chemotherapy alone before surgery is accepted and radiotherapy is held in reserve. Where it is threatened, radiotherapy is given. The decision to omit it is taken at a tumour board, never by one doctor.
Not on its own. A flexible colonoscope over-estimates distance because it follows a curve. The measurement that counts is taken on a rigid scope and confirmed against the height stated on the pelvic MRI.
