ICG-Guided Sentinel Lymph Node Dissection: Sparing a Full Pelvic Clearance
August 27, 2026
In robotic hysterectomy for carcinoma of the endometrium, Dr. Alka Dahiya uses ICG, indocyanine green, fluorescence-guided sentinel lymph node dissection. The technique targets only the sentinel node rather than removing the entire pelvic lymph node basin, and it depends on the robotic system's fluorescence imaging capability to identify that node reliably.
Why sparing the full dissection matters
Full pelvic lymph node dissection carries a real cost in lymphoedema, nerve injury and general operative morbidity. When the sentinel node is clearly identified and comes back negative, sentinel lymph node dissection achieves equivalent staging accuracy with substantially less of that morbidity. This is one of the reasons endometrial carcinoma is, in Dr. Dahiya's view, a field where robotics is particularly useful: the patient population is frequently obese and carries hypertension, diabetes or corpus cancer syndrome, all of which make open or laparoscopic surgery more challenging and more likely to produce complications.
What it looked like in practice
A 56-year-old patient with early-stage endometrial carcinoma underwent robotic hysterectomy with ICG-based sentinel lymph node dissection. The sentinel node uptake was clearly visible intraoperatively, only those nodes were removed, and the full pelvic lymph node basin was left untouched. The patient has been on observation for six months with no evidence of disease.
This guide is based on a live Jivo Masterclass — Dr. Alka Dahiya taught doctors across Africa on March 29, 2026.
FROM THE LIVE Q&A
Dr. William
What is the average cost of a robotic surgery, for example a robotic hysterectomy for endometriosis?
Dr. Alka Dahiya
Cost depends on the exact procedure. For endometriosis surgery, whether it involves removing the uterus or only a cystectomy changes the figure, but in Indian currency the cost is typically 4 to 5 lakhs, roughly 4,000 to 5,000 US dollars.
Frequently Asked Questions
For someone coming from a general medicine background in gynaecology rather than a surgical one, what is the process for training in robotic surgery in India?▼
A basic surgical background is required. Admission into a robotic training course in India requires an MS in Obstetrics & Gynaecology or MS in General Surgery, with at minimum some exposure to procedures such as LSCS, so the surgeon understands the underlying operative anatomy and principles. Without that foundation, the transition is very difficult. Requirements vary by country, and it would be worth checking what pathways exist locally.
How long does it take to train to become competent in robotic surgery, what does that training cost, and is it necessary to train in laparoscopy first?▼
It is definitely possible to train in robotics directly, and many surgeons find it easier to learn than laparoscopic surgery, especially if they are already comfortable with open surgery. India has a three-step pathway supported by Intuitive: Level 1 is simulation-based certification, Level 2 requires 30 to 50 procedures completed independently or under supervision, and Level 3 is advanced training. There is no requirement to learn laparoscopy first, though prior exposure helps. Most surgeons gain confidence within a year of focused training, with a trained bedside assistant supporting the docking and undocking process.
Is it possible to visit your centre for training, or to join a fellowship there?▼
Yes. BLK-Max takes two robotic fellows every year, one in surgical oncology and one specifically in gynaecologic oncology, each for a one-year fellowship in minimally invasive robotic surgical oncology. The full application procedure and selection criteria would be shared afterward through the Jivo Healthcare team.

What is ICG-guided sentinel lymph node dissection?▼
It is a fluorescence-guided technique using indocyanine green, or ICG, that targets only the sentinel lymph node during robotic hysterectomy for endometrial carcinoma, relying on the robotic system's fluorescence imaging to identify that node reliably.
Why does sparing a full pelvic lymph node dissection matter for endometrial cancer patients?▼
Full pelvic lymph node dissection carries a real cost in lymphoedema, nerve injury and general operative morbidity. When the sentinel node is clearly identified and negative, sentinel lymph node dissection achieves equivalent staging accuracy with substantially less of that morbidity.
Why is endometrial carcinoma considered a field where robotic surgery is particularly useful?▼
The patient population is frequently obese and carries hypertension, diabetes or corpus cancer syndrome, all of which make open or laparoscopic surgery more challenging and more likely to produce complications.
