Understanding Escar: A Guide to Surgical Incisions and Minimally Invasive Procedures

Escar is a type of surgical incision or cut made in the skin to allow for the insertion of a surgical instrument or device. It is commonly used in laparoscopic and endoscopic procedures, where a small incision is made to allow for the insertion of a camera or other instruments. The term "escar" is derived from the Latin word "excindere," which means "to cut out."

Escar is used in a variety of medical procedures, including:

1. Laparoscopic surgery: A minimally invasive procedure in which a laparoscope (a thin tube with a camera and light) is inserted through several small incisions to visualize the inside of the abdomen or pelvis.
2. Endoscopy: A procedure in which an endoscope (a flexible tube with a camera and light) is inserted through an escar to visualize the inside of the body, such as the colon, esophagus, or lungs.
3. Surgical biopsy: A procedure in which a sample of tissue is removed from the body through an escar for examination under a microscope.
4. Drain placement: An escar may be used to place a drainage tube in the body, such as after a surgical procedure or to drain excess fluid.
5. Wound closure: An escar may be used to close a wound or incision after surgery.

Overall, escar is an important technique in minimally invasive surgery and endoscopy, allowing for the insertion of instruments and devices through small incisions, reducing the risk of complications and promoting faster healing.
