Surgical Oncology
Rectal Cancer
Rectal cancer is an adenocarcinoma arising from the last 15 cm of the large intestine. Because of its anatomically narrow pelvic structure, surgical planning requires special experience; total mesorectal excision (TME) is the oncological standard.
Overview
The robotic technique allows nerve-sparing dissection in the narrow pelvic region, with lower blood loss and a higher rate of sphincter preservation. In locally advanced cases, neoadjuvant chemoradiotherapy is planned.
Who Is It For?
- Those with complaints of blood in the stool and a change in bowel habits
- Patients diagnosed with rectal cancer by endoscopic biopsy
- Those diagnosed with locally advanced disease for whom surgery is planned after neoadjuvant treatment
- Cases of recurrent rectal tumours deemed suitable by a multidisciplinary board
Treatment Process
- 1
Pre-Assessment & Diagnosis
The diagnosis is confirmed and the stage of the disease clarified through a detailed history, physical examination and the necessary imaging and laboratory tests.
- 2
Planning & Preparation
An anaesthesia consultation, bleeding profile and review of any accompanying conditions are carried out; a multidisciplinary council decision is taken when needed.
- 3
Procedure / Operation
The procedure is performed with the technique most suitable for the patient (laparoscopic, robotic or open); tissue integrity and oncological principles are preserved.
- 4
Follow-up & Monitoring
Early mobilization, pain control and wound monitoring are provided; suture removal and a general assessment check-up are planned after discharge.
Recovery & Aftercare
With robotic TME the rate of sphincter preservation is high; for some low tumours, a temporary protective ileostomy may be planned.
Hospital Stay
5–8 days
Recovery Time
3–5 weeks
Follow-up
Day 10, week 6, month 3
Frequently Asked Questions
Is the bag (stoma) permanent in rectal cancer surgery?
No, in most cases not. A permanent colostomy may be needed only for very low-lying tumours. In some cases a temporary (3 to 6 month) protective ileostomy is created and later closed.
If the tumour disappears completely after neoadjuvant treatment, is surgery still essential?
A 'watch and wait' approach can be applied in selected patients who achieve a complete clinical response, in experienced centres. The decision is made by a multidisciplinary board.
Is robotic rectal surgery nerve-sparing?
Yes. The three-dimensional vision and precise movement of the robotic system protect the pelvic autonomic nerves, reducing loss of urinary and sexual function.
When is adjuvant chemotherapy recommended?
It is decided according to the pathology result, stage and response to neoadjuvant treatment; it is recommended as standard in cases with lymph node involvement.
