Robotic Surgery (da Vinci) in Johannesburg

What it involves

Dr Marais is a certified da Vinci console surgeon on the Intuitive Surgical robotic platform. The da Vinci system provides 3D high-definition magnified vision and EndoWrist instruments — tools that bend and rotate the way a human wrist does, but inside the abdomen. It is the same minimally invasive philosophy as laparoscopy, extended to anatomy where fine wristed articulation and depth perception make a real difference.

A da Vinci operation has three components: the surgeon console (where the surgeon sits, hands in the controls, eyes on a stereoscopic 3D view), the patient cart (four robotic arms docked to laparoscopic ports on the patient), and the vision cart (the imaging and processing system linking them). The surgeon's hand movements are scaled and translated to instrument tips inside the body, with natural hand tremor filtered out electronically.

Certification as a da Vinci console surgeon is a structured pathway: didactic training on the platform, simulation and cadaveric work, proctored initial cases, and documented case volumes before independent practice. It is a specific qualification on top of specialist surgical training — not something every surgeon offering laparoscopic surgery holds.

Dr Marais is trained on the da Vinci system (also written DaVinci) built by Intuitive Surgical — the most widely used robotic surgery platform worldwide, with a track record across general, hernia, colorectal, urological and gynaecological surgery.

For the patient, the experience and recovery closely mirror laparoscopic surgery: several small (5–12 mm) incisions, same-day or one-night hospital stay for most procedures, and a return to desk work within a week for straightforward cases. Where the robot earns its place is inside the operation — better visualisation and finer articulation in tight anatomical spaces mean a more precise repair.

When it's indicated

The clearest current benefit is in complex hernia work — inguinal, ventral, incisional and hiatal repair — where the robot's wristed instruments help with delicate dissection and precise mesh placement, particularly in obese patients, recurrent hernias, and larger defects. Select upper-GI, adrenal and endocrine cases are also candidates.

The approach

The robot is a tool, not a decision. The right operation for you is the one that gives the safest, most durable result — sometimes that's robotic, sometimes conventional laparoscopy, occasionally open. Dr Marais discusses honestly when a robotic approach genuinely changes the outcome for your case and when it doesn't.

Recovery

Broadly the same as laparoscopic surgery: same-day or one-night stay for most procedures, walking within hours, desk work within a week, gym at three to four weeks. Small port-site incisions heal to short lines that fade over months.
