Skip to main contentAhmedabad and Gandhinagar · Dr Harsh Shah, Rectal Cancer Surgeon
A cancer in the middle third of the rectum sits far enough from the sphincter that the bowel can almost always be rejoined — the operation is an anterior resection with total mesorectal excision, and a permanent bag is rarely the answer. The question that actually decides your treatment is a different one: do you need radiotherapy at all? For a group of mid-rectal cancers the answer is now no, and chemotherapy alone before surgery is enough. Your pelvic MRI decides which group you are in.

Rectal Cancer Surgeon
· Apollo Hospital, Bhat, Gandhinagar · Gota OPD, Ahmedabad
Qualified twice over in surgical gastroenterology and in practice long enough to have followed these decisions out over years rather than weeks. Rectal cancer is the part of gastrointestinal surgery where the plan made in the first fortnight decides how the next twenty years feel, so it is made carefully and it is made by a team.

Middle rectal cancer means a tumour sitting in the middle third of the rectum, roughly six to eleven centimetres from the anal verge. It matters because at that height there is room below the tumour to take a clear margin and still rejoin the bowel — which is not always true a few centimetres lower.
The rectum is about fifteen centimetres long and surgeons divide it into thirds for an entirely practical reason. The height of the tumour, measured from the anal verge, decides how much bowel has to come out below it, whether the sphincter is in danger, and how much of the surrounding fatty envelope — the mesorectum — has to be removed. A mid-rectal tumour and a low rectal tumour are the same disease with two different operations and two different consequences.
So Dr Harsh Shah insists the height is recorded properly, and recorded twice. It is measured at the first visit on digital rectal examination, and again on a rigid sigmoidoscopy, because a flexible scope loops in the sigmoid and consistently reports a tumour as higher than it is. A cancer wrongly filed as mid-rectal when it is in fact low leads to a plan the anatomy will not support — and the correction then has to be made in theatre, which is the worst place to make it.
The symptom that brings most people in is bleeding. Dark blood mixed through the stool rather than sitting on top of it, blood with mucus, a change in bowel habit that has lasted weeks, a feeling of needing to go that does not settle afterwards, unexplained weight loss or an anaemia nobody can explain — each of those deserves an examination of the rectum. Dr Harsh Shah does not treat piles, fissures or fistulas. He does, regularly, see rectal cancers that were called piles for months by somebody who never examined the rectum.
A pelvic MRI is the pivotal test in rectal cancer, and no treatment decision is made before one exists. The scan, not an impression formed at examination, decides whether chemotherapy comes first, whether radiotherapy is added, and how much mesorectum has to be removed.
What Dr Harsh Shah asks the radiologist for is a structured report rather than a paragraph: how deeply the tumour has grown through the bowel wall, the distance from the tumour to the mesorectal fascia — the envelope the surgeon dissects along — whether tumour is growing inside the veins outside the bowel wall, the state of the lymph nodes, and the height from the anal verge. A report that leaves the margin distance out is sent back, because that single measurement is what the whole plan turns on.
| Test | What it decides | When |
|---|---|---|
| Digital rectal examination | Height from the anal verge, which quadrant, whether the tumour moves on the wall or is fixed | First visit, always |
| Rigid sigmoidoscopy with biopsy | Confirms the diagnosis and records the true height — a flexible scope over-estimates it | First visit or soon after |
| Pelvic MRI | The pivotal test — depth, margin threat, veins, nodes. It decides whether radiotherapy is needed | Before any treatment decision |
| Full colonoscopy | Looks for a second tumour higher in the colon, which is found in a small but real number of people | Before surgery, or within a few months after if the bowel was obstructed |
| CT of chest, abdomen and pelvis | Whether the disease has spread beyond the pelvis | With the MRI |
| CEA blood test | A baseline to follow afterwards; it is a tracking number, not a diagnosis | Before treatment |
| MMR / MSI testing on the biopsy | Identifies the small group whose cancer responds to immunotherapy | On every rectal cancer |
Rectal cancers are sorted into three groups on the MRI, and the group decides the sequence. Early tumours go straight to surgery. Tumours that have grown through the wall but whose margin is safely clear can be treated with chemotherapy alone before surgery, leaving radiotherapy out. Tumours that threaten or involve the margin need radiotherapy, and all of the treatment is given before the operation.
This is where a middle rectal cancer differs most from a low one. Pelvic radiotherapy works, but it is not free: it leaves lasting effects on bowel function, on sexual and urinary function, and on fertility. For years it was given to almost everybody with a tumour through the bowel wall. It is now clear that where the MRI shows the margin is comfortably clear, chemotherapy before surgery does the same job, with radiotherapy held in reserve for those whose tumour does not respond. Mid-rectal tumours are the ones most often eligible, and it is worth knowing whether you are.
| What the MRI shows | What is offered | Why |
|---|---|---|
| Early tumour, margin clear, nodes negative | Straight to surgery — anterior resection with total mesorectal excision | Nothing is gained by delaying; chemotherapy is decided afterwards on the pathology |
| Through the wall, margin comfortably clear, limited nodes | Chemotherapy alone before surgery, with radiotherapy left out | Avoids the lasting pelvic effects of radiotherapy without giving up cancer control |
| Margin threatened or involved, tumour in the veins, bulky nodes | All chemotherapy and radiotherapy first, surgery afterwards | Shrinks the tumour away from the margin, and treats hidden disease while you are strongest |
| Tumour obstructing the bowel | A defunctioning stoma first, then treatment, then the resection | An emergency resection of an unstaged rectal cancer is an oncological error |
Every one of these decisions is taken in a multidisciplinary meeting, not by the surgeon alone. Dr Harsh Shah’s rule is stricter for the rectum than for any other part of the bowel: every case goes to the meeting once the MRI and CT exist, and every decision to leave radiotherapy out goes back to it. When surgery follows radiotherapy, it is deliberately spaced some weeks afterwards, because operating into a freshly irradiated pelvis is asking for trouble at the join and at the wound.
For a middle rectal cancer the standard operation is an anterior resection: the segment of rectum carrying the tumour is removed inside its intact fatty envelope, and the bowel above is joined to the rectum below. A temporary ileostomy is often made to protect that join while it heals, and it is closed a few months later.
The part of the operation that decides whether the cancer comes back in the pelvis is not the join — it is the envelope. The rectum sits inside a sheet of fat and lymph nodes called the mesorectum, wrapped in a thin membrane. The whole point of the operation is to dissect in the bloodless plane just outside that membrane and deliver the specimen with the envelope unbroken and a clear rim of normal tissue all the way round it. For a mid-rectal tumour the mesorectum is taken well below the tumour rather than all the way to the pelvic floor, which is one of the reasons function afterwards is usually better than it is for a low tumour.
The pathologist grades the quality of that envelope on the specimen and reports how close the tumour came to the cut edge. Dr Harsh Shah treats those two lines of the histology report as a personal audit of the operation, not as paperwork, and they are discussed with you at the two-week review.
Two judgements are made in theatre and are worth knowing in advance. The first is the protecting ileostomy: it does not stop a join from leaking, but it changes a leak from a catastrophe into something manageable, and for a low join it is usually the right trade. The second is that a tumour stuck to a neighbouring structure is never peeled off it — it comes out together with whatever it is stuck to, or the operation has failed its purpose.
On approach, the operation can be done open, laparoscopically or with the robot, and all three are acceptable in experienced hands. What is being measured is the quality of the specimen, not the size of the incision. Dr Harsh Shah selects the approach for the individual pelvis and converts without hesitation if the plane is being lost, which is a decision made in the patient’s favour rather than the technique’s.
Fertility preservation has to be discussed before pelvic radiotherapy, not after it, and stoma siting is marked by the stoma nurse before theatre even when a stoma is only a possibility. Both are routinely forgotten and neither can be undone afterwards.
Pelvic radiotherapy affects fertility, and the conversation about preserving sperm or eggs is time-critical: once treatment has begun the opportunity has gone. For anyone of reproductive age it is raised at the first consultation, before the plan is finalised, however awkward the timing feels in the same week as a cancer diagnosis.
The stoma site is marked on your abdomen by the stoma nurse while you are sitting, standing and lying, because a stoma placed without that marking can sit in a crease or under a waistband and make the next few months far harder than they need to be. It is marked even when the plan is to avoid a stoma, because plans change on the table.
Preparation before the operation is deliberate rather than routine: anaemia corrected in advance rather than transfused on the day, sugars brought under control, smoking and alcohol stopped several weeks ahead, nutrition addressed where somebody has lost weight, and the bowel prepared with oral antibiotics as well as the usual preparation. Clear fluids are allowed until close to theatre, and you sit out of bed and drink on the day of the operation itself.

From the first consultation to full recovery there are five stages, and at each one you are told what happens next and when.
Rectal cancer surgery is covered by most health insurance policies and by cashless arrangements at Apollo Hospital, Bhat. The estimate depends on the operation planned, the room category, the length of stay and whether chemotherapy or radiotherapy forms part of the treatment — so it is prepared for your case rather than quoted from a list.
What moves the estimate: which operation is done and by which approach; whether a protecting ileostomy is made and later reversed, which is a second short admission; the room category you choose; how long you stay, which is longer if recovery is complicated; whether the plan includes chemotherapy or radiotherapy alongside surgery; and the pathology and imaging needed to plan the treatment and to follow you afterwards.
On insurance, the office prepares the pre-authorisation paperwork with the clinical justification attached, and cashless approval is sought before admission wherever the policy allows. Bring the policy document, your ID, previous hospital records, all imaging on disc as well as on film, and the biopsy report. Where a policy declines something, the reason is explained to you plainly and an appeal is drafted if there are grounds for one.
Almost never. At that height there is room to take a clear margin below the tumour and still rejoin the bowel. What is common is a temporary ileostomy to protect the new join while it heals, closed a few months later once treatment is finished and the join has been checked.
Sometimes, and mid-rectal cancers are where it is most often possible. Where the MRI shows the critical margin is comfortably clear, chemotherapy alone before surgery is an accepted route, with radiotherapy kept in reserve for anyone whose tumour does not respond. It does not apply where the margin is threatened or involved — those tumours need radiotherapy.
After radiotherapy, surgery is deliberately spaced some weeks afterwards. The tumour continues to shrink during that window, and operating into a freshly irradiated pelvis raises the risk to the join and to the wound. The exact timing is set by the team and you are given the date rather than left waiting for one.
The approach matters less than the quality of the specimen that comes out. Open, laparoscopic and robotic total mesorectal excision are all acceptable in experienced hands, and the robot has an ergonomic advantage deep in a narrow pelvis. Dr Harsh Shah chooses the approach for the individual pelvis and converts without hesitation if the dissection plane is being lost.
It depends which scope measured it. A flexible scope loops and routinely over-estimates the height, so a tumour reported at 10 cm on a flexible scope can sit lower on a rigid one. Dr Harsh Shah re-measures it at the first visit, because the height changes how much mesorectum has to come out.
