[Intraluminal anorectal ultrasonography in the staging of anal canal cancer].
The staging of anal canal carcinoma is essential to establish the surgical procedure, either a local excision or abdominoperineal resection. In addition to the conventional studies we have used the anorectal endosonography in seven patients with carcinoma of the anal canal. The preoperative staging was done according to the UICC classification. The endosonography gave significant information of the anal anatomy to assess an accurate diagnosis in six patients, two of them had tumors invading the vagina. In one case, the ultrasound image was underestimated. Overall accuracy of the endosonographic assessment was 85.7 percent. Anorectal endosonography correctly assesses the anatomy layers of the anal canal and offers a good tumor's staging.
