Linear endo-ultrasonographic signs of muscularis propria invasion in early rectal cancer.

ABSTRACT:

Background and study aim

Local resection of early rectal cancer is being increasingly used. With invasion of the muscularis propria layer of the rectal wall, the risk of lymph node metastasis becomes too high to consider this the optimal oncological treatment. Therefore, a diagnosis of muscular invasion is important before attempting local resection; however, endoscopic and magnetic resonance imaging (MRI) images have limitations, such as overstaging (26-31%). We investigated the potential of linear endoscopic ultrasound (L-EUS) in the diagnosis of muscularis propria invasion.

Patients and methods

The study consisted of a development phase, in which linear (L)- EUS features, associated with muscular wall invasion were searched and tested, and a validation phase, during which
