Robotic Ilioinguinal Lymph Node Dissection (R-ILND)
This procedure is often associated with the term R-VEIL (Robotic Video-Endoscopic Inguinal Lymphadenectomy). I have included this terminology as patients often search for it.
FAQs: Robotic Ilioinguinal Lymph Node Dissection
(Minimally Invasive Groin Surgery)
Section 1: The Procedure Explained
Q: What is Robotic Ilioinguinal Lymph Node Dissection? A: This is a specialized surgery to remove lymph nodes from the groin (inguinal area) and often the pelvis (iliac area). It is primarily used to treat or stage penile cancer and certain skin cancers (like melanoma) that have spread to these nodes.
Q: What is the difference between "Open" surgery and the Robotic approach? A: This is the most important question.
Traditional Open Surgery: Requires a large incision (10–15 cm) in the groin crease. It has a high risk of skin complications, wound breakdown, and infection.
Robotic/VEIL Approach: We use 3 small "keyhole" incisions (1–2 cm) on the thigh. We work under the skin to remove the nodes without making a large cut. This preserves the skin, drastically reducing wound complications and pain.
Q: What is R-VEIL? A: R-VEIL stands for Robotic Video-Endoscopic Inguinal Lymphadenectomy. It is the technical name for the minimally invasive removal of groin lymph nodes using the robotic system. It offers the same cancer control as open surgery but with faster recovery.
Section 2: During the Surgery
Q: How long does the surgery take? A: The procedure typically takes 2 to 3 hours per side. If both groins need to be treated, they can often be done in the same setting.
Q: Will I be asleep? A: Yes, the surgery is performed under general anesthesia.
Q: Do you remove all the lymph nodes? A: We perform a thorough dissection within specific anatomical boundaries (femoral triangle) to ensure all potentially cancerous nodes are removed for accurate staging and treatment. If the deep pelvic nodes (iliac nodes) are also involved, the robot allows us to access those through the same or separate small ports without a large abdominal cut.
Section 3: Recovery & Drains
Q: Will I have drains coming out of my leg? A: Yes. This is standard for all groin lymph node surgeries.
The lymphatic system carries fluid. After nodes are removed, this fluid (lymph) needs a place to go while your body heals.
You will wake up with a small plastic tube (drain) in your thigh. It prevents fluid from building up under the skin (seroma).
Q: How long do the drains stay in? A: The drains usually stay in for 1 to 3 weeks, depending on how much fluid is coming out. You will go home with the drain and will be taught how to empty and measure it easily. We remove it in the clinic once the output decreases.
Q: How long is the hospital stay? A: With the robotic approach, most patients are discharged in 1 to 2 days. (Compared to 5–7 days for open surgery).
Section 4: Risks & Long-Term Care
Q: What is Lymphedema, and will I get it? A: Lymphedema is chronic swelling of the leg caused by the removal of lymph nodes.
Risk: It occurs in about 20–30% of patients, regardless of whether surgery is open or robotic.
Management: We recommend wearing compression stockings after surgery to support the leg and minimize swelling. Keeping the leg elevated when sitting also helps.
Q: When can I walk and drive? A:
Walking: You can and should walk on the evening of surgery.
Driving: You can drive once you are off pain medication and can move your leg comfortably (usually 2 weeks).
Q: Is the cancer cure rate the same as open surgery? A: Yes. Multiple studies have shown that the robotic (VEIL) approach retrieves the same number of lymph nodes and provides the same oncological safety as the open technique, just with fewer wound complications.
Patient Guide: Caring for Your Surgical Drain
What is this drain?
After lymph node surgery, your body produces fluid (lymph) as it heals. The small plastic tube and bulb you see are there to collect this fluid. This prevents it from building up under your skin, which helps you heal faster and reduces the risk of infection.
The bulb works by suction (vacuum). For the drain to work, the bulb must remain squeezed (compressed) at all times.
Step-by-Step: How to Empty Your Drain
You will need to empty the bulb when it gets about half full, or at least 3 times a day (morning, afternoon, and before bed).
1. Prepare
Wash your hands thoroughly with soap and water.
Gather your supplies: the measuring cup (given to you at the hospital) and your Drain Output Log.
2. Open & Empty
Unplug the stopper from the top of the bulb. The bulb will expand and fill with air—this is normal.
Turn the bulb upside down and gently squeeze the fluid into the measuring cup. Do not touch the inside of the stopper or the pouring spout with your fingers.
3. Measure & Record
Look at the measuring cup and note exactly how many milliliters (mL) or cc’s of fluid came out.
Write the date, time, and amount in your log.
4. Reactivate the Suction (Crucial Step!)
Before you put the stopper back in, squeeze the bulb flat in your hand to push all the air out.
While keeping it squeezed flat, push the stopper back into the spout firmly.
Release your grip. The bulb should stay collapsed/flat. If it stays flat, the suction is working.
5. Clean Up
Flush the fluid down the toilet. Rinse the measuring cup with water.
Wash your hands again.
Troubleshooting
Q: The fluid looks different. Is that okay?
Normal: Initially, the fluid is bloody (red). Over the next few days, it will turn pink, then light yellow or clear/straw-colored.
Cloudy/Milky: If you had lymph nodes removed, the fluid might look milky white. This is chyle and can be normal, but mention it to your doctor.
Q: The tubing seems clogged.
You may see small clots or stringy material in the tube. This is common.
"Milking" the tube: With one hand, pinch the tube near your skin to hold it steady. With the other hand, pinch the tube below that and slide your fingers down toward the bulb to push the clot through. Do not pull hard on the tube where it enters your skin.
Q: The bulb won't stay flat (loses suction).
Check the stopper: Is it closed tight?
Check the skin site: Is the tube leaking fluid around the hole in your skin?
If you cannot get the bulb to hold suction, call the office.
⚠️ When to Call the Doctor
Contact us immediately if:
Fever: You have a temperature over 101°F (38.3°C).
Redness: The skin around the drain site becomes bright red, hot, or very painful.
Sudden Bleeding: The drainage turns bright red again and fills the bulb very quickly.
No Drainage: The drain stops producing fluid abruptly, but you feel fluid sloshing under your skin or notice swelling.
It Falls Out: If the drain accidentally gets pulled out, cover the hole with a bandage and call us. Do not try to put it back in.
Drain Output Log (Example)
Please bring this log to your follow-up appointment. We need these numbers to decide when to remove the drain.
Here is a Drain Output Log Template designed to be printed on the back of your instruction sheet.
Daily Drain Output Log
Patient Name: __________________________
Surgery Date: __________________________
Instructions:
Empty your drain at least 3 times a day (Morning, Afternoon, Evening) or whenever the bulb is half full.
Record the exact amount in milliliters (mL) or cc.
Add up the amounts at the end of the day to get the 24-Hour Total. This number helps us decide when to remove the drain.
