pneumodissection
Pronunciation: NEW-moh-dih-SEK-shun
The use of gas insufflation to separate tissue planes during minimally invasive surgery.
Full Definition
A surgical technique employing controlled gas insufflation to create tissue plane separation without mechanical dissection. Most commonly used in extraperitoneal procedures, pneumodissection allows visualization of anatomical spaces through gas expansion. The technique is particularly valuable in TEP hernia repairs and retroperitoneal surgery, where it creates working space while preserving tissue integrity.
