Single-Incision Laparoscopic Surgery: Procedure, Instruments, Benefits & Recovery

Single-Incision Laparoscopic Surgery: Procedure, Instruments, Benefits & Recovery

Single-Incision Laparoscopic Surgery (SILS) is a minimally invasive surgical approach that allows selected abdominal and pelvic procedures to be performed through a single skin incision, commonly located near the umbilicus.

Unlike conventional laparoscopic surgery, which generally uses multiple small incisions, SILS places the laparoscope and working instruments through one access site.

This approach may offer improved cosmetic outcomes and fewer visible scars. However, the technique presents unique challenges involving instrument movement, visualization, and surgical ergonomics.

Single-incision laparoscopic surgery is used in selected general surgery, gynecology, urology, and pediatric surgical procedures.

This JDMeditech guide explains SILS surgery, its applications, surgical instruments, advantages, limitations, complications, recovery, and frequently asked questions.

What Is Single-Incision Laparoscopic Surgery?

Single-Incision Laparoscopic Surgery is a minimally invasive technique that uses one surgical access site rather than several separate incisions.

The incision is commonly made within or near the umbilicus, where the resulting scar may be less noticeable.

A specialized single-port access device or suitable access arrangement allows the introduction of a laparoscope and working instruments.

The surgeon performs the planned operation using compatible instruments and visualization equipment.

However, the precise equipment configuration depends on the surgical procedure and the chosen technique.

What Does SILS Stand For?

SILS stands for Single-Incision Laparoscopic Surgery.

The technique is also associated with several related terms:

• Single-Port Laparoscopic Surgery
• Single-Incision Laparoscopy
• Single-Site Laparoscopic Surgery
• Single-Port Access Surgery
• Laparoendoscopic Single-Site Surgery (LESS)
• Single-Incision Minimally Invasive Surgery
• Transumbilical Laparoscopic Surgery

However, terminology may vary between conventional single-port laparoscopy and dedicated robotic single-port surgical systems.

How Does Single-Incision Laparoscopic Surgery Work?

Single-incision laparoscopic surgery uses one primary incision to access the abdominal cavity.

First, the surgeon establishes an appropriate access site, commonly near the umbilicus.

Next, a suitable access device is positioned to accommodate the laparoscope and compatible working instruments.

Carbon dioxide insufflation may be used to create a suitable working space inside the abdominal cavity.

The surgeon then performs the planned operation using laparoscopic visualization and specialized instruments.

Finally, the instruments are removed and the incision is closed using an appropriate technique.

However, additional ports or conversion to conventional laparoscopy or open surgery may be necessary when clinically indicated.

Single-Incision Laparoscopic Instruments and Functions

How Is Single-Incision Laparoscopic Surgery Performed?

A qualified surgeon performs single-incision laparoscopic surgery in an appropriately equipped hospital.

First, the healthcare team reviews the patient’s medical history, clinical condition, and planned operation.

Next, the anesthesia team prepares the patient for the procedure.

During surgery, the surgeon establishes an appropriate single-site access point.

A laparoscope and compatible working instruments are introduced through the access system.

The surgeon performs the required operation using laparoscopic visualization and specialized instruments.

Finally, the surgical team completes the procedure and closes the access incision.

However, additional ports or conversion to conventional laparoscopic or open surgery may be necessary for patient safety.

Potential Benefits of Single-Incision Laparoscopic Surgery

1. One Primary Surgical Incision

SILS generally uses one primary skin incision instead of several separate incisions.
