Robotic Surgery Knowledge Centre
The next step beyond laparoscopic surgery — robot-assisted operations give the surgeon 3D HD vision and wristed, tremor-free instruments for unmatched precision in complex GI, bariatric, hernia and cancer surgery, performed by Dr. Avinash Tank.
Procedures
Robot-assisted sleeve gastrectomy and gastric bypass — especially valuable for higher-BMI patients, giving precise stapling and suturing through a thicker abdominal wall with less strain and excellent accuracy.
Learn more 02 Robotic Hernia RepairRobotic repair of complex, recurrent and large ventral, incisional, inguinal and hiatus hernias — wristed instruments allow precise mesh placement and defect (TAR) closure for durable, low-recurrence results.
Learn more 03 Robotic Anti-Reflux & Hiatus Hernia SurgeryRobot-assisted fundoplication and hiatus-hernia repair for severe acid reflux (GERD) — the fine, magnified control of the robot is ideal for accurate, lasting reflux correction deep at the diaphragm.
Learn more 04 Robotic Colorectal SurgeryRobotic surgery for colon and rectal cancer — superb access for total mesorectal excision in the narrow pelvis, with better nerve preservation (continence and sexual function) and sphincter-saving outcomes.
Learn more 05 Robotic GI Cancer SurgeryRobot-assisted curative surgery for stomach, oesophagus, pancreas and liver cancers — precise dissection around major vessels with less blood loss, fewer complications and faster recovery than open surgery.
Learn more 06 Robotic Gallbladder SurgeryRobot-assisted (including single-site) gallbladder removal for complex or difficult gallstone disease — enhanced 3D vision for a safe view of the bile-duct anatomy and a near-scarless result.
Learn moreWhat this centre covers
Robotic surgery is an advanced form of laparoscopic (minimally-invasive) surgery. Instead of holding instruments by hand, the surgeon sits at a console and controls precise robotic arms while viewing a magnified, high-definition 3D image inside the body. The robot does not operate on its own — it faithfully translates the surgeon's movements, filtering out tremor and scaling motion, so even the most delicate steps deep inside the abdomen or pelvis can be done with exceptional accuracy. The benefits to you are the same as laparoscopic surgery — small cuts, less pain, less blood loss and a faster recovery — with even greater precision in complex cases.
When robotic surgery helps most
For complex, deep or delicate operations — narrow-pelvis rectal cancer, large or recurrent hernias, anti-reflux surgery at the diaphragm, and surgery in higher-BMI patients — the robot's wristed instruments and 3D vision reach and manoeuvre where the human hand and straight laparoscopic tools struggle. The result is more accurate dissection, finer suturing, better preservation of nerves and function, and fewer complications.

How Robotic Surgery Works
You are operated on by Dr. Avinash Tank — the robot never acts on its own; it precisely follows the surgeon's hands.
A magnified, high-definition 3D camera shows the anatomy in far greater detail than the naked eye.
Tiny wristed instruments bend and rotate like a human wrist (and better), with tremor filtered out.
A few small cuts mean less pain, lower infection risk and a quick return to normal life.

Frequently asked questions
It is very safe. The robot does not operate by itself — your surgeon controls every movement from a console. It simply gives finer, steadier, more precise control than is possible by hand.
For many routine operations laparoscopic is excellent and enough. For complex, deep or delicate surgery — narrow-pelvis cancer, large/recurrent hernias, anti-reflux, higher-BMI bariatric — the robot's 3D vision and wristed instruments add real precision and can mean fewer complications and better function.
Yes — like all minimally-invasive surgery, you can expect small cuts, less pain, less blood loss and a faster return to normal life, often with a shorter hospital stay.
It can cost a little more than standard laparoscopic surgery, but you get a written, transparent estimate up front, and we help with cashless insurance and EMI options.
