To accurately assess the depth of cancer invasion, endorectal ultrasound was performed using a radial scanner (Aloka, 7.5 MHz) in 145 patients with rectal cancer. High-resolution ultrasound clearly depicted five- or seven-layer echographic structures in the normal rectal wall, and demonstrated cancer as a hypoechoic lesion. These layer structures provided an important feature in determining the depth of cancer invasion. Rectal cancers of 122 patients were examined thoroughly by endorectal… Expand
Endorectal ultrasonography for the assessment of wall invasion and lymph node metastasis in rectal cancer
Endorectal ultrasonography with a flexible-type radial scanner was applied to 120 patients with rectal cancer and was considered a very useful tool for the assessment of the depth of cancer invasion in the rectal wall and pararectal lymph node metastasis. Expand
Endorectal ultrasonography with a 7.5 MHz linear array scanner for the assessment of invasion of rectal carcinoma
Endorectal ultrasonography with the 7.5 MHz linear array scanner was considered to provide useful information in deciding on the type of operation offered to the patient, although there was some difficulty in making the distinction between mucosal and submucosal lesions. Expand
Use of transrectal ultrasound to evaluate direct tumour spread and lymph node status in patients with rectal cancer.
Pre-operative assessment of patients with rectal cancer using transrectal ultrasound is a useful technique which may assist the surgeon in his choice of operation and in the selection of those patients who may benefit from pre-operative radiotherapy. Expand
Influence of tumor position on accuracy of endorectal ultrasound staging
Endorectal ultrasound is currently the best method for preoperative assessment of the depth of infiltration of rectal tumors, however, rectal anatomy seems to affect staging accuracy in the lower rectum because the structure of the ampulla recti renders endosonographic examination more difficult. Expand
Accuracy of endosonography in the staging of rectal cancer treated by radiotherapy
While the endosonographic accuracy for lymph node involvement was similar in the two groups, wall invasion was correctly ascertained but in only 47 per cent in group B (P < 0·05), after irradiation, the thickening of the rectal wall and the poor visualization of the hyperechoic layers hampered interpretation.

New staging techniques. Endoscopic ultrasound
Rectal ultrasonography allows detailed images of rectal tumors and provides the most accurate method of staging rectal cancer, and future developments in ultrasound‐guided fine‐needle aspiration cytology holds promise for more accurate assessment of lymph node status. Expand
Anorectal ultrasound for neoplastic and inflammatory lesions.
The role of ERUS in the staging of rectal and anal carcinoma, as well as for perianal inflammatory conditions, is widened by new developments in ERUS and anal endosonography. Expand
Endosonography for Preoperative Staging of Rectal Tumours
Endosonographic assessment of perirectal nodal involvement seems to be too unreliable to be used for the preoperative selection of patients, however, the use of endoluminal ultrasound in thePreoperative evaluation of local tumour spread is confirmed. Expand
Two- and Three-dimensional Ultrasonography in Benign and Malignant Rectal Neoplasms
The role of anorectal US in evaluating the extent of tumor invasion in the rectal wall, sphincter muscles, and perirectal lymph nodes; the extentof tumor invasion following radiotherapy; and detecting early local recurrence in the Rectal wall or perirecta lymph nodes is discussed. Expand
Rectal endosonography in the evaluation of stenotic rectal tumors
Full sonographic visualization of stenotic rectal tumors and thus evaluation of tumor extension can be achieved by using forwardlooking endoprobes. Expand


Evaluation of echographic diagnosis of rectal cancer using intrarectal ultrasonic examination
Preoperatively performed intrarectal ultrasonography provides valuable information concerning the choice of operating methods for rectal cancer, and local lymph node metastases were diagnosed preoperatively. Expand
Transrectal ultrasonography for the assessment of invasion of rectal carcinoma
An experimental study using fresh specimen revealed that the middle low echoic layer of the rectal wall corresponded to the muscularis propria, and future studies, using a sonographic probe with higher frequency and better resolution, are expected to produce valuable benefits in deciding indications for local excision of rectal carcinomas. Expand
Preoperative staging of rectal cancer by intrarectal ultrasound
An analogous to the TNM classification for postoperative pathologic tumor staging, a preoperative tumor staging based on ultrasonic determination of the infiltrative depth of tumor is proposed, which is called u TNM. Expand
The use of computerized tomography scan in the staging and follow-up study of carcinoma of the rectum.
It is appropriate to recommend that pelvic CT scan be a routine test for every patient who has had abdominoperineal resection or low anterior resection for carcinoma of the rectum and rectosigmoid. Expand
Management of rectal carcinoma: impact of computed tomography.
Twenty-one patients with rectal carcinoma were examined preoperatively in order to assess the accuracy of CT in recognizing the extraluminal extension of the tumor and its effect on treatmentExpand
Detection and staging of primary rectal and rectosigmoid cancer by computed tomography.
Thirty-nine patients were examined by computed tomography (CT) prior to resection of primary rectal [23] or rectosigmoid carcinoma [16]. There were 3 patients in Stage II [thickened bowel (greaterExpand
