Hasson technique
Pronunciation: HAS-son
An open method of establishing laparoscopic access through direct visualization rather than blind trocar insertion.
Full Definition
The Hasson technique, also known as open laparoscopy, involves making a small incision and inserting the trocar under direct visualization rather than blind insertion. This method reduces the risk of major vessel and bowel injury during initial access. The technique involves opening the peritoneum under direct vision, inserting a blunt trocar, and securing it with sutures or a specialized Hasson trocar with built-in retention system. It's particularly useful in patients with previous abdominal surgery, obesity, or other risk factors for adhesions.
Usage
Usage note: Capitalize as it's named after Harrith Hasson. Common misspelling is 'Hassan'.
