What is single incision surgery?

Single incision surgery is performed through one incision made in the patient’s abdomen, typically hidden within the natural fold of the bellybutton. This differs from standard laparoscopic surgery, which typically involves 3-5 incisions. The single incision approach is the latest advancement in minimally invasive surgery. The photo to the left features a patient’s abdomen just six weeks after undergoing a single incision gallbladder removal using the GelPOINT system.


What is the GelPOINT System?

Surgeons can perform a variety of procedures through a single incision with the GelPOINT system, enhancing cosmetic results and potentially minimizing pain. The GelPOINT system consists of two main components: the GelSeal cap and the Alexis wound protector/retractor. The Alexis wound protector/retractor is inserted into the incision site at the beginning of the procedure. It allows the surgeon a better view of the working site and protects the incision site. Once the Alexis protector/retractor is placed, the GelSeal cap is fitted on top. Surgical instruments are passed through the GelSeal cap into the abdomen, as seen in the cross section to the right.


What is Surgical Site Infection (SSI)?

SSI is an infection that occurs after surgery at the same part of the body that the surgery took place.Ref Symptoms include redness, pain or fluid drainage surrounding the location of the surgery, and/or a fever. Ref


How does SSI affect patients?

On average, wound infection patients:
  • spend an additional 7-10 days in the hospital Ref
  • are 60% more likely to spend time in ICU Ref
  • are 5 times more likely to be readmitted to the hospital Ref
  • have a 2-11 times higher risk of death than patients without an SSI Ref
  • require an additional cost of $11,087 to $34,670 per infection Ref

How does SSI affect healthcare?

  • SSI has added $3 to $10 billion to the cost of healthcare in the United States Ref
  • 2% to 5% of patients undergoing inpatient surgery will develop an SSI Ref
  • there were over 290,000 cases of SSI in 2002, which resulted in over 8,000 deaths Ref

How does the Alexis Wound Protector/Retractor protect patients from SSI? Ref

The Alexis Wound Protector/Retractor is a medical device made of a sheath connecting two rings. The device retracts, or draws back, the incision and simultaneously protects the wound. By creating a barrier around the incision, the sheath protects the surgical site from exposure to organisms that may cause an infection, whether it is from the air, the patient’s own bodily microorganisms or contact during the procedure. Studies have shown that using the wound protector/retractor reduces superficial surgical site infection following colorectal surgeries. Ref


What is a trocar?

A trocar is a medical device that provides access to the abdominal cavity during a laparoscopic procedure. Laparoscopy is a minimally invasive procedure typically performed through 3-5 small incisions in a patient’s abdomen, using a camera for visualization. Trocars are placed within each incision and surgical instruments, along with the camera, are passed through them.

A trocar consists of three primary components:

  1. Cannula: A cannula is a tube-shaped shaft placed in the patient to allow access into the abdominal cavity during a laparoscopic procedure
  2. Seal: Located at the top of the cannula, the seal allows instruments to pass through the cannula while preventing air from escaping from the abdominal cavity. Maintaining proper air pressure is key during a laparoscopic procedure because it allows surgeons to properly view the surgical field.
  3. Obturator: The obturator is a mechanism that allows the cannula to penetrate the abdomen.

What are laparoscopic instruments?

Laparoscopy is a minimally invasive procedure typically performed through 3-5 small incisions in a patient’s abdomen and using a camera for visualization. Laparoscopic instruments are designed to perform a procedure through tubes that are placed in the abdomen, known as trocars.

  • Scissors — Scissors transect, or cut across, tissue.
  • Dissectors — Dissectors separate tissue along their natural lines of separation. In addition to dissecting, these medical devices may also grasp and mobilize, or move, tissue.
  • Graspers — Graspers allow surgeons to manipulate tissue just as they would with their hands. Depending on the jaws of the graspers, the devices can grab hold of fine, delicate or fibrous tissue.
