Brief introduction: Transrectal 360°intracavitary high-frequency ultrasound can clearly display the 5-layerstructure of the rectal wall in all directions, so it can detect the depth ofrectal tumor invasion (T stage), peri-intestinal lymph node metastasis (Nstage), tumor distance from the anus,
The distance between the levator ani muscle and the mesangial fascia, tumorhardness, the relationship between tumor and peritoneal reflex, circumcisionrate, etc. make a diagnosis, which provides important information forclinicians to choose appropriate surgical methods.
Scope of application: anorectal tumors
Features and advantages: ①Slim probe, less pain, safe and non-radiation,reproducible, less complications; ②360°all-round scanning; ③frequencyconversion (5～10MHz), suitable for detecting tumors of different depthsfrom the anal canal mucosal surface, resolution
High; ④Diagnosing the depth of anorectal tumor invasion (T staging) and thepresence or absence of lymph node metastasis around it has a higher diagnosticefficiency than other diagnostic methods, providing a reliable basis for theselection of preoperative surgical options.
