Single-Incision Laparoscopic Surgery (SILS)
Scarless Gallbladder Removal Through the Navel
Overview
Single-Incision Laparoscopic Surgery (SILS) — also known as Single-Port Surgery, LESS (Laparo-Endoscopic Single-Site Surgery), or 'scarless surgery' — is an advanced minimally invasive technique in which the entire gallbladder removal is performed through a single small incision hidden within the navel. The result is a virtually invisible scar, as the navel's natural contours conceal the incision site.
What Is Single-Incision Laparoscopic Surgery?
In standard laparoscopic cholecystectomy, 3–4 separate port incisions are made in the abdomen. SILS achieves the same result using only one incision — typically 2–2.5 cm — placed within the umbilicus (navel). A specialised multi-channel port is inserted through this single incision, allowing the camera and all surgical instruments to pass through the same entry point.
SILS requires advanced laparoscopic skills because the instruments are all parallel to each other (rather than triangulated as in standard laparoscopy), creating a more challenging operative environment. It is therefore performed by surgeons with specific training and experience in single-port techniques.
The cosmetic result is outstanding — within 6–12 months, the incision is completely hidden within the navel's natural folds, and most patients have no visible scar. SILS is particularly popular among younger patients, those concerned about body image, and patients who want the most cosmetically superior result.
How the Procedure Works
- 1General anaesthesia is administered
- 2A single 2–2.5 cm incision is made within the umbilicus (navel)
- 3A specialised multi-channel single-port device is inserted
- 4Carbon dioxide gas is insufflated to create a working space
- 5A 5 mm HD camera and articulating instruments are inserted through the single port
- 6The cystic duct and artery are identified and divided using the same triangulation principles as standard laparoscopy
- 7The gallbladder is dissected from the liver bed
- 8The gallbladder is retrieved through the single umbilical port
- 9The port is removed, the fascia is closed with a single absorbable suture, and the skin is closed with a subcuticular stitch
- 10The incision is hidden within the navel — virtually invisible
Who Needs This Procedure?
- Symptomatic gallstones in patients prioritising cosmetic outcome
- Younger patients (especially women) concerned about visible scarring
- Patients with a BMI under 35 (ideal body habitus for SILS)
- Uncomplicated gallstone disease without severe inflammation
- Patients who have had previous abdominal surgery through the navel (may not be suitable)
- Patients who have been counselled about slightly longer operative time and potential conversion to standard laparoscopy
Key Benefits
Virtually No Visible Scar
The single incision is hidden within the natural folds of the navel. Within 6–12 months, most patients have no visible scar — ideal for those who wear swimwear, crop tops, or are concerned about body image.
Less Post-Operative Pain
Some studies suggest SILS causes less post-operative pain than standard laparoscopy due to fewer incisions, though results vary between patients.
Rapid Recovery
Recovery time is similar to standard laparoscopic surgery — most patients return to desk work in 5–7 days and full activity in 2–3 weeks.
Same-Day Discharge
SILS is performed as a day-care procedure in eligible patients, with discharge on the same day as surgery.
Proven Safety
SILS cholecystectomy has been performed worldwide since 2007 with a safety profile comparable to standard laparoscopy in experienced hands.
Advanced Technique
SILS represents the cutting edge of minimally invasive surgery — a technically demanding procedure that requires specialist training and experience.
How to Prepare
- Same pre-operative workup as standard laparoscopic surgery
- Detailed counselling about SILS technique, benefits, and potential conversion to standard laparoscopy
- Assessment of body habitus and previous abdominal surgery history
- Fasting: nothing to eat or drink for 6–8 hours before surgery
- Stop blood thinners as advised by Dr. Patil
- Arrange for a responsible adult to accompany you home
Recovery Timeline
Rest at home. Mild pain around the navel is normal. Take prescribed pain medication. Clear fluids progressing to soft foods. Avoid driving.
Most patients feel significantly better. Light activities around the house. Short walks encouraged. Desk work possible for most patients by day 5–7.
Resume normal diet. Avoid heavy lifting (>5 kg). Can resume driving once off strong pain medication.
Full return to all activities. The umbilical incision continues to heal and becomes increasingly invisible over the following months.
Diet After Surgery
- Day 1–3: Clear fluids and light soups
- Day 4–7: Soft, low-fat foods
- Week 2 onwards: Gradual return to normal diet
- Avoid very fatty, fried, or spicy foods for the first 4 weeks
- Stay well hydrated
Potential Risks & Complications
All surgical procedures carry some risk. Dr. Patil will discuss these with you in detail during your consultation. The following risks are rare but important to be aware of:
- Slightly longer operative time compared to standard laparoscopy (15–20 minutes more)
- Higher conversion rate to standard laparoscopy (3–8%) if anatomy is difficult
- Umbilical hernia at the port site (slightly higher risk than standard laparoscopy due to larger fascial defect)
- Same risks as standard laparoscopy: bile duct injury, bleeding, infection
- Not suitable for all patients — obese patients, those with severe inflammation, or complex anatomy may not be candidates
When to Seek Immediate Medical Help
Contact Dr. Patil or go to the nearest emergency department if you experience any of the following after your procedure:
- Fever above 38.5°C
- Increasing pain around the navel not controlled by medication
- Redness, swelling, or discharge from the umbilical incision
- Jaundice (yellow skin or eyes)
- Persistent vomiting or inability to eat
- Bulging at the navel site (may indicate hernia)
Cost & Insurance Coverage
Estimated Cost
₹55,000 – ₹95,000 (slightly higher than standard laparoscopy due to specialised equipment)
Insurance
SILS is covered under most comprehensive health insurance plans. Some insurers may classify it as a standard laparoscopic procedure; others may require additional documentation. Our team will verify your coverage and assist with pre-authorisation.

Frequently Asked Questions
Is SILS safe compared to standard laparoscopic surgery?
Yes. In experienced hands, SILS has a comparable safety profile to standard laparoscopic cholecystectomy. The key requirement is surgeon experience with the technique. Dr. Patil has specific training in SILS and performs it regularly. The main difference is a slightly higher conversion rate to standard laparoscopy (3–8%) when anatomy is challenging.
Who is the ideal candidate for SILS?
The ideal SILS candidate is a patient with uncomplicated gallstone disease, a BMI under 35, no previous major abdominal surgery, and a strong preference for the best cosmetic outcome. Patients with severe acute cholecystitis, morbid obesity, or complex anatomy are better served by standard laparoscopy or robotic surgery.
Will I really have no scar after SILS?
The incision is placed within the navel, which naturally conceals it. Within 6–12 months, the vast majority of patients have no visible scar. However, individual healing varies — some patients may have a slightly visible mark within the navel. The cosmetic result is significantly superior to standard laparoscopy in all cases.
Is SILS more painful than standard laparoscopy?
Pain levels are generally similar. Some patients report slightly less pain with SILS due to fewer incisions. The most common discomfort is around the navel incision site, which is larger than standard laparoscopic ports. Shoulder tip pain from CO2 gas is the same as with standard laparoscopy.
What happens if SILS cannot be completed through a single incision?
If the anatomy is too difficult or there is unexpected bleeding, Dr. Patil will add one or two additional ports to complete the procedure safely as standard laparoscopy. This is not a complication — it is a safety decision. The patient still benefits from minimally invasive surgery with a small additional incision.
