Advanced Robotic Colorectal Surgery
Combining surgical precision with advanced robotic technology to deliver radical cancer resections, faster recovery, and optimal functional preservation.
Lead Profile & Surgical Philosophy
Pioneering Precision in Colorectal Cancer Care
Mr Alistair Slesser is a high-volume Consultant Colorectal Surgeon specializing in minimally invasive and robotic colorectal cancer surgery. Utilizing state-of-the-art robotic platforms, Mr Slesser offers patients highly specialized, radical surgical procedures designed to maximize cancer clearance while minimizing post-operative pain, scarring, and hospital stay.
Every patient’s treatment plan is built on precision, evidence-based surgical oncology, and a commitment to preserving nerve and bowel function.
Robotic Colorectal Cancer Surgery
Robotic Complete Mesocolic Excision (CME) & Central Vascular Ligation
The Technique: For right-sided colon cancers, CME involves dissecting along embryonic tissue planes to remove the tumor intact within an untouched mesocolic envelope, along with extensive central lymph node clearance.
Patient Benefits: Maximizes oncological resection quality, reduces local recurrence risk, and provides accurate pathological staging without increasing surgical morbidity.
Totally Robotic Intracorporeal Anastomosis (ICA)
The Technique: Unlike traditional keyhole approaches where the bowel is pulled outside through a larger abdominal incision to be rejoined, ICA utilizes robotic precision to rejoin (suture) the bowel entirely inside the abdominal cavity.
Patient Benefits: Allows for significantly smaller extraction incisions (often hidden low in the bikini line), reduced post-operative pain, faster return of bowel function, and lower incisional hernia rates.
The Technique: Operating deep within the narrow confines of the pelvis, the 3D high-definition magnification and wrist-articulating instruments of the robotic platform allow for meticulous TME plane dissection.
Patient Benefits: Critical autonomic pelvic nerves responsible for urinary and sexual function are carefully visualised and preserved, while achieving optimal circumferential resection margins (CRM).
Robotic Rectal Cancer Surgery & Total Mesorectal Excision (TME)
Why Choose Robotic Surgery?
Enhanced 3D Magnification: Offers 10x magnified, high-definition views of delicate tissue planes and nerve plexuses.
7 Degrees of Instrument Freedom: Wristed instruments eliminate tremor and allow effortless maneuverability in restricted spaces like the deep pelvis.
Reduced Recovery Time: Smaller incisions and gentler tissue handling translate to less post-operative pain, earlier discharge, and a rapid return to daily activities.
