An ultra-low rectal cancer sits at the very bottom of the rectum, at or inside the ring of muscle that gives you control. Whether that muscle can be kept is not a matter of the surgeon’s preference or of how modern the equipment is. It is decided by an examination, a height measured on a rigid scope, and a pelvic MRI that states in writing whether the tumour has reached the sphincter. Where it has, an abdominoperineal excision with a permanent colostomy is the operation that clears the cancer. Where it has not, the sphincter is kept. Dr Harsh Shah tells you which of the two you are facing before anything is booked.

Rectal Cancer Surgeon
· Apollo Hospital, Bhat, Gandhinagar · Gota OPD, Ahmedabad
Trained in the country’s leading surgical gastroenterology programmes and qualified twice over in the speciality, Dr Harsh Shah operates on the rectum as a dedicated practice rather than as one item on a general list — and rectal cancer is the abdominal cancer where the difference between a good operation and an adequate one is visible to the pathologist, in the intactness of the specimen envelope. Google rating 4.89 from 216 reviews at the Gota clinic, and 4.94 from 17 reviews at the Apollo, Bhat listing.
A tumour is called rectal when it sits within fifteen centimetres of the anal opening. Ultra-low means the last few centimetres — level with, or growing into, the sphincter complex, the double ring of muscle that holds stool until you choose to pass it. There is very little room between the tumour and that muscle, and the muscle cannot be rebuilt once it is gone. Most bleeding from the back passage is harmless; the commonest reason a cancer this low is found late is that the bleeding was explained away as piles and the rectum was never examined.
The internal sphincter keeps you continent while you sleep. The external sphincter and the levator muscles above it are the voluntary part you squeeze to hold on. A tumour a centimetre higher can be removed while leaving both intact; a tumour grown into them cannot, because clearing the cancer means taking the muscle with it. Which is why the height is measured, not estimated — on a rigid scope, never a flexible one, because a flexible scope consistently reports a tumour as higher than it is.
What should prompt an examination: dark blood mixed into the stool rather than bright blood on the paper, blood with mucus, a change in bowel habit, tenesmus, a sense that evacuation is never complete, iron-deficiency anaemia, unexplained weight loss. Dr Harsh Shah does not treat piles, fissures or perianal fistula — but he will not let a rectal cancer be labelled as one of them.
Rectal cancer is an MRI-driven disease, and no treatment decision is made here before a synoptic pelvic MRI exists — a report that answers each question in turn rather than describing the pelvis in general terms. For an ultra-low tumour the line that matters most is the one about the sphincter and the levator muscles. If the report does not mention them, it is not finished.
| Step | Test | What it decides |
|---|---|---|
| 1 | Digital rectal examination | Height from the anal verge, quadrant, fixity, sphincter involvement, and your baseline continence |
| 2 | Rigid sigmoidoscopy with biopsy | Confirms the cancer, and fixes the height on the measurement that counts |
| 3 | Full colonoscopy | Looks for a second tumour higher up |
| 4 | Pelvic MRI — the pivotal test | T stage, distance to the mesorectal fascia, extramural venous invasion, nodes, height, and sphincter and levator involvement |
| 5 | CT of chest, abdomen and pelvis; CEA | Whether the disease has spread, and the baseline to follow afterwards |
| 6 | MMR or MSI testing on the biopsy | Identifies Lynch syndrome, and the patients for whom immunotherapy works |
The digital examination is mandatory at first contact here, and for tumours this low it is diagnostic more often than any test that follows — including what your control is like beforehand, because a sphincter already weak will not usefully be preserved. Two further steps belong in every ultra-low case and are routinely forgotten elsewhere: fertility preservation is arranged before pelvic radiotherapy, because sperm or egg storage cannot be done retrospectively; and the stoma nurse marks a site on your abdomen before theatre for any operation that could produce a stoma, even where it is unlikely. Every case then goes to the tumour board, because whether the sphincter can be preserved is precisely the question the protocol names as requiring a board discussion rather than one surgeon’s opinion.
A tumour this low is high-risk by its position alone, and high-risk rectal cancer is treated with all of its chemotherapy and radiotherapy before the operation rather than after. That shrinks the tumour away from the sphincter and the pelvic side wall, delivers the drug treatment while you are still strong enough to take it, and sometimes changes the answer about the muscle. Surgery follows eight to twelve weeks after radiotherapy ends, because operating into a freshly irradiated pelvis is a known cause of wound failure.
So the operation is usually months away, and that time is being used rather than lost. Four situations need no operation: a very small, favourable early tumour removable through the back passage; a tumour that disappears completely after treatment and can be watched instead; a patient too frail for major pelvic surgery, better served by gentler radiotherapy and supportive care; and an obstructing tumour, which needs a defunctioning stoma first — never an emergency resection, because a rectum removed before it was staged cannot be staged afterwards.
Watching rather than operating is a programme, not a shortcut: examination, endoscopy and pelvic MRI every three to four months for two years, then six-monthly, and salvage surgery accepted if the cancer regrows. Dr Harsh Shah will not offer it to a patient who cannot realistically attend that follow-up.
The oncological constant is total mesorectal excision — the rectum removed inside its own intact fatty envelope, dissected in the natural plane around it, with a clear margin at the circumference. What changes between patients is whether the sphincter comes out with it. If the muscle is clear and your control was good beforehand, the bowel is joined to the anal canal and a temporary ileostomy protects the join. If the muscle is involved, or control was already poor, an abdominoperineal excision removes the rectum, the anal canal and the sphincter together, and a permanent colostomy is formed.
A tumour is never peeled off a structure it has grown into — it comes out in one piece with that structure or not at all. Where a low join is made, a temporary ileostomy is formed as a matter of course: it does not prevent a leak, but it turns a catastrophic leak into a manageable one, and a join this low is the highest-risk anastomosis in abdominal surgery. Every low join is tested on the table before the abdomen is closed. The approach, open or keyhole, is chosen for the tumour and the pelvis rather than for the brochure. An abdominoperineal excision also leaves a second wound at the perineum, the part of this operation that most often heals slowly, particularly after radiotherapy.
Dr Harsh Shah counsels the risks personally; the figures that apply to you are given at that discussion. The risks particular to a very low rectal operation: a leak from the join and the pelvic collection that can follow it; a temporary ileostomy intended for closure at three to six months which in a proportion of patients is never closed; a permanent colostomy, certain where an abdominoperineal excision is done; injury to the ureter; disturbance of sexual function, commoner after radiotherapy; difficulty passing urine, which is why the catheter is left longer after this operation; slow healing or breakdown of the perineal wound; narrowing of the join later; a hernia at the incision or around the stoma years afterwards; and a risk to life, higher in an emergency and higher after radiotherapy.
One more belongs here, because it is the commonest long-term complaint and the most often sprung on patients afterwards. Where the bowel has been joined to the anal canal, many patients develop urgency, frequency, clustering of motions and some loss of control — a pattern named low anterior resection syndrome. It improves over one to two years and may not fully resolve. It is counselled before the operation here, never explained afterwards, and it is treatable with bowel retraining, medication, pelvic floor physiotherapy and irrigation. It is also why a permanent colostomy is sometimes the better of two lives rather than the worse.

Unedited Google reviews from patients treated for rectal cancer by Dr Harsh Shah, quoted word for word with the original spelling.
No single figure covers this treatment, because the path differs so much between patients. Someone whose tumour disappears after radiotherapy and is watched has a different course entirely from someone facing months of chemotherapy, a major pelvic operation and a stoma. What can be given is a written estimate for each stage before that stage happens, and a cashless pre-authorisation wherever the policy allows.
What moves the estimate: planned admission or emergency; how much radiotherapy and chemotherapy comes first; the approach used at surgery; whether a stoma is formed and whether it is temporary or permanent; length of stay and room category; and whether a second admission for stoma closure follows. Plan that closure into the budget at the start. Bring the policy document and card, photo identity, the scans on disc, the biopsy and blood reports, and your medicines with doses.
Not definitely. It depends on whether the tumour has reached the sphincter muscle and on how good your control was beforehand — and that answer is often reassessed after radiotherapy and chemotherapy, because a tumour that has shrunk away from the muscle can sometimes be removed while keeping it.
The tumour board, on the evidence — the examination, the height on a rigid scope, and a pelvic MRI stating whether the sphincter and levator muscles are involved. It is one of the specific situations where a board discussion is required rather than optional.
Not always, and this surprises people. Where the bowel is joined very low, many patients live with urgency, frequency and some loss of control for a year or two afterwards. A well-sited, well-taught colostomy is predictable in a way a poorly functioning low join is not, and for a patient whose control was already weak it is often the better life.
Radiotherapy to the pelvis may end fertility permanently, which is why storing sperm or eggs is discussed before radiotherapy starts and not after. It is time-critical and the step most often missed elsewhere — raise it at the first consultation even if nobody else has.
Usually between four and six days. The catheter stays two to three days after this operation because the pelvic nerves need time to recover, and the step that decides your discharge date is stoma independence — changing the appliance without help.
