FAQs About SILS™

Traditional Laparoscopic

SILSTM Technique
What exactly is the SILSTM procedure and how does it work?

The SILS (single incision laparoscopic surgery) procedure is a laparoscopic surgical procedure using a single incision (through the belly button) to accomplish any number of treatments including gallbladder removal, gynecologic procedures (like hysterectomies) and others. By utilizing just one 20mm incision, the SILS procedure avoids the multiple entry points---usually involving up to four ½-inch or smaller incisions---required by traditional laparoscopic techniques.

Who is a candidate for the SILSTM procedure?
Generally, candidates for laparoscopic surgery are also candidates for the SILSTM procedure. Criteria may include: no prior surgery and an elective or non-emergent case.

How are SILSTM procedures different from other laparoscopic surgical procedures?
Instead of requiring the four ½-inch or smaller incisions associated with traditional laparoscopic surgery that may leave visible scars, the SILSTM procedure is accomplished with a single 20mm incision through the belly button resulting in the potential for no visible scar.

Moreover, a single incision minimizes the pain that may be associated with the additional sites of entry.

What studies or clinical trials have been conducted to assess the safety of the SILSTM procedure?
Covidien is sponsoring the first prospective randomized controlled trial comparing traditional laparoscopic cholecystectomy vs. SILSTM cholecystectomy. The purpose of this trial is to evaluate the benefits of SILSTM Port cholecystectomy vs. conventional 4-port laparoscopic cholecystectomy.

SILSTM cholecystectomy was first described in 1997. Since that time the SILSTM procedure has been used to perform numerous additional procedures (e.g., appendectomy, hysterectomy, nephrectomy, etc.).

How do surgeons learn how to perform these procedures?
The Covidien SILSTM training program offers extensive education on this advanced minimally invasive surgical procedure, providing surgeons with the tools and knowledge necessary to carry out this new technique. The training program consists of 4 modules that include both lectures and hands-on product training to ensure surgeons are comfortable with both the equipment and the techniques. For qualified surgeons, the SILSTM training can be completed within a single day. Surgeons may need to conduct several procedures to master the technique.

The SILSTM procedure is an advanced laparoscopic technique for which specialty training is strongly recommended. Contact your local Covidien Surgical Device Specialist for training opportunities.

What instruments are utilized to perform SILSTM procedures?
Specialized instrumentation manufactured by Covidien provides surgeons with the necessary tools to conduct SILSTM procedures.

  • SILSTM Port
    The SILSTM Port is the first device specifically indicated for multiple instrument access through a single incision. The SILSTM Port facilitates the insertion of 3 hollow tubes or cannulae through which instruments are passed. The SILSTM Port features a valve that allows surgeons to inflate the abdomen for optimal instrument access. It provides stability/support for hand instruments, maximum movement of instruments, and can be easily removed.
  • SILSTM RoticulatorTM Instruments
    The RoticulatorTM instrumentation consists of 2 distinct components that work together to provide surgeons with maximum versatility and range of motion. The first component is a 5mm shaft that is designed for 360-degree rotation. The second component is the instrument tip, which is capable of 80-degrees of movement left to right and top to bottom. These unique features enable the RoticulatorTM instruments to facilitate hand-like access to difficult anatomy and provide improved ease of use.

Are there risks associated with the SILSTM procedures?
Yes, any surgical procedure can result in complications. According to the Agency for Healthcare Research and Quality, potential problems of any surgery could include pain, injury to organs, bleeding, infection, hernia, adhesions and scarring. Evidence currently supports that traditional laparoscopic procedures generally result in better quality-of-life outcomes than open surgery, but the SILSTM procedure itself has yet to undergo this evaluation.
