Sphincter-preserving surgery and total mesorectal excision (TME) for rectal malignancies, aimed at cure with the best functional outcome.
Rectal cancer needs a more precise surgical approach than colon cancer because of its location deep in the pelvis, close to the sphincter muscles that control continence. Dr. Krishna Pada Saha uses total mesorectal excision (TME) — the internationally recognised gold-standard technique — combined with a sphincter-preserving approach whenever oncologically safe, so patients can be treated for cure while protecting quality of life afterward.
Because the rectum sits deep within the bony pelvis, close to the bladder, sexual organs and sphincter muscles, rectal cancer surgery demands a level of precision that colon cancer surgery does not. Many patients also need neoadjuvant chemoradiation before surgery to shrink the tumour and improve the chances of a sphincter-sparing operation. Dr. Saha plans each case with a full multidisciplinary work-up — MRI pelvis for local staging, CT for distant staging, and coordinated oncology input — so that the sequence of chemoradiation and surgery is tailored precisely to each tumour's location and stage.
Recognising these early can help you seek timely, effective treatment.
Every patient is different — Dr. Saha recommends the safest, least invasive option that will give lasting results.
A clear, step-by-step path from consultation to full recovery.
A detailed history and clinical examination to accurately assess your condition and rule out other anorectal issues.
Based on the severity and your overall health, Dr. Saha recommends the most appropriate — and least invasive — treatment path.
The procedure is performed under local, spinal or general anaesthesia as appropriate, most often on a day-care basis.
Recovery is closely supervised, with attention to bowel function and continence as much as wound healing. Most patients are guided through a staged return to normal diet and routine.
Detailed pelvic MRI staging guides the exact surgical and treatment plan for each tumour.
Total mesorectal excision performed to internationally recognised oncological standards.
Continence is protected whenever oncologically safe to do so.
Surgery is sequenced with neoadjuvant treatment as one connected cancer care plan.
TME is the internationally recognised gold-standard technique for rectal cancer surgery, removing the rectum together with its surrounding lymphatic envelope intact for the best cancer clearance.
Many rectal cancers benefit from neoadjuvant chemoradiation to shrink the tumour before surgery — this is decided individually based on stage and MRI findings.
Whenever oncologically safe, Dr. Saha uses sphincter-preserving techniques so patients can avoid a permanent stoma.
Regular clinical review, blood markers and periodic scans are advised for several years to monitor for recurrence.
Not always — many patients avoid a permanent stoma through sphincter-preserving TME surgery; a temporary stoma is sometimes used to protect healing and is later reversed.
It's chemotherapy and radiation given before surgery to shrink certain rectal tumours, improving the chances of complete removal and sphincter preservation.
