Abstract
Rectal endoscopic ultrasound (RUS) has proven very beneficial in the staging of malignant neoplasm in the anus and rectum (1,2). Typically, imaging is performed using an adult standard radial ultrasound endoscope, commonly used in evaluation of the upper gastrointestinal tract (3). Based on RUS, the normal rectal wall architecture consists of a mucosal layer (muscularis mucosa and lamina propria—also referred to as superficial and deep layers), submucosa, muscularis propria, and surrounding perirectal fat tissue without a serosa/adventiaa layer (2). Carcinoma appears as a hypoechoic mass lesion with partial or total destruction of the normal wall layer. RUS has also been useful in examining for tumor invasion in the surrounding regional organs: which in males would include evaluating the bladder, seminal vesicles, prostate, and internal anal sphincters (IASs)/external anal sphincters (EASs); and in females would include evaluation of the bladder, uterus/vagina, and IASs/EASs (2,2). Moreover, RUS is very helpful in evaluation of malignant lymphadenopathy. All of these features are useful in the pre-operative staging of rectal and anal carcinomas (1,2).
