Minimally invasive surgery has transformed patient care over the past two decades. Techniques that once relied on large incisions have given way to approaches that shorten recovery, reduce pain, and improve cosmetic outcomes. One of the newest advancements in this trend is LESS surgery or Laparo-Endoscopic Single–Site Surgery – a technique that allows surgeons to perform an entire operation through a one small incision. As demand for faster, less visible, and less painful surgical options grows, single-incision surgery has become quite a popular choice for patients and surgeons alike.
In this article, we will get to know about what LESS surgery is and why it is gaining so much attention. Also, we will get to know how it works and who the best surgeon for this surgery is.
What is LESS Surgery?
LESS Surgery is a type of minimally invasive technique, performed through a single incision, usually hidden behind the patient’s belly button. Instead of creating three to five incisions (as in standard laparoscopy), the surgeon works through just one entry point using specialized instruments.
LESS is now used in many common procedures, including:
- Gallbladder removal
- Appendectomy
- Hernia repair
- Gynaecological surgeries like ovarian cysts, hysterectomy, and endometriosis treatment.
By reducing the number of incisions, LESS offers a combination of cosmetic and recovery-related benefits.
How LESS Surgery Works?
Although the procedure uses only one incision, it requires highly advanced tools and precision.
#1. A Single Umbilical Incision
The incision is typically made inside the natural fold of the belly button, making the end result nearly invisible.
#2. Specialized Port and Instruments
A multi-channel port is placed into the incision. Through this port, the surgeon inserts:
- A thin camera
- A light source
- Long, flexible instruments designed to maneuver in tight spaces.
#3. Enhanced Visualization
High-definition imaging helps compensate for the limited access point, giving surgeons a clear internal view despite working through a single incision.
Benefits of LESS Surgery
#1. Virtually Scarless Results
Because the incision is hidden inside the navel, many patients appear to have no visible scar, a major factor driving demand.
#2. Reduced Pain
Fewer incisions mean fewer pain points. Patients often report lower discomfort levels compared to traditional laparoscopy.
#3. Faster Recovery
Patients may be able to:
- Go home sooner
- Resume normal activities more quickly
- Experience less post-operative soreness
#4. Lower Risk of Certain Complications
With fewer incisions, the risk of:
- Wound infections
- Trocarsite Hernias
- Postoperative bleeding may be reduced.
Why are Single-Incision Procedures Becoming Popular?
#1. Growing Patient Demand for “Scarless” Surgery
Cosmetic outcomes have become increasingly important to patients. LESS Surgery aligns with this trend by offering a nearly invisible result.
#2. Major Advances in Technology
Improvements in:
- Flexible cameras
- High-definition visualization
- Multi-channel ports
- Energy and sealing devices
- Articulating instruments have made single-site access safer and more feasible.
#3. Increased Surgeon Training and Adoption
More surgeons are completing advanced laparoscopic and robotic training programs, expanding their ability to perform LESS surgery safely and efficiently.
#4. Influence of Social Media and Aesthetic Awareness
Patients share recovery experiences online, increasing awareness of minimally invasive options, and encouraging others to seek out scarless procedures.
Who is a Good Candidate for LESS Surgery?
Ideal candidates often include patients who:
- Are undergoing normal or routine abdominal or pelvic procedures.
- Have minimal scar tissue from previous surgeries.
- Are at a healthy weight.
- Do not have a complex internal anatomy or single inflammation.
When LESS may not be recommended
Patients with severe obesity, prior complicated surgeries, or complex disease may be advised to undergo standard laparoscopy or open surgery instead. Only a surgeon can determine whether LESS is appropriate based on individual anatomy and medical needs.
Risks and Considerations
While LESS is safe and effective for many patients, it does come with unique considerations:
- Instrument crowding: Working through one port requires advanced skill.
- Longer surgical time in complex cases.
- Conversion to multi-port laparoscopy may occur if additional access is needed.
- Choosing an experienced surgeon trained in single-site and multi-port techniques is essential.
LESS Surgery vs. Traditional Laparoscopy vs. Robotic Surgery
| Feature | LESS | Traditional Laparoscopy | Robotic Surgery |
|---|---|---|---|
| Number of Incisions | 1 | 3–5 | 3–5 |
| Scarring | Almost none | Minimal | Minimal |
| Pain | Often lower | Low | Low |
| Cost | Usually similar | Generally standard | Often higher |
| Best For | Cosmetic priority, straightforward cases | Most routine surgeries | Complex or delicate procedures |
No single technique is “best” for every patient; the choice depends on the surgeon’s expertise and the specifics of the condition.
What to Expect Before, During, and After LESS Surgery
Before Surgery
- Preoperative consultation
- Blood tests or imaging
- Review of medical history
- Discussion of risks and benefits
During Surgery
- Performed under general anesthesia
- Typically lasts about the same time as traditional laparoscopy
- The entire operation is completed through one incision
After Surgery
- Mild soreness near the belly button
- Most patients walk the same day
- Return to work or regular activities can be quicker than with multi-port surgery
- The incision typically heals almost invisibly
Conclusion: The Future of Single-Incision Surgery
As patient expectations evolve and surgical technology continues to advance, LESS surgery is rapidly becoming a leading minimally invasive option. It offers a combination of cosmetic, comfort, and recovery benefits that many patients find compelling. While it isn’t suitable for everyone, its increasing popularity shows that single-incision techniques represent a significant step forward in the evolution of modern surgery.
