closed entry technique
A method of initial trocar insertion using a sharp trocar without direct visualization of entry.
Full Definition
A traditional laparoscopic access method where the first trocar is inserted blindly through the abdominal wall, typically at the umbilicus, without direct visualization of the entry point. This technique contrasts with open (Hasson) or optical trocar methods. While faster to perform, closed entry carries higher risks of major vessel or bowel injury, making careful patient selection and technique crucial for safety.
Usage
Usage note: Specify trocar size and entry site when documenting this technique.
