Endoscopic ultrasonography in staging rectal cancer.

Endoscopic ultrasonography (EUS) was used to stage rectal cancer by assessing depth of invasion through bowel wall layers and/or involvement of lymph nodes. EUS findings were correlated with histopathologic findings to discern the usefulness of this modality in predicting which patients could be candidates for sphinctersaving procedures and the avoidance of abdominoperineal resection. The Olympus EU-M3 endoscopic ultrasound system was used to assess depth of penetration through rectal wall layers and to identify lymph nodes. Comparison of EUS findings to histopathologic findings was possible in 13 patients. EUS agreed with histopathology in 9 of 13 cases (69.3%) ( p = 0.07, kappa statistic). EUS agreed with histopathology as the presence or absence of lymph nodes in 9 of 13 cases (69.3%) (p = 0.07). However, the presence of lymph nodes could not necessarily predict metastatic involvement of these nodes. In one patient, invasion of vaginal cuff was correctly predicted. In nine cases, computed tomographic analysis (CT) was available for comparison to EUS in detection of penetration beyond the bowel wall. CT agreed with histopathology in 3 of 9 (33%), whereas EUS agreed with histopathology in 7 of 9 (78%).

[Real-time ultrasonics: a method of hand imaging].

Seventy-five surgically soft-tissue lesions of the hand were examined prospectively by real-time ultrasound and correlated with surgical and pathological findings. The normal ultrasonic anatomy of the hand is described. The use of real time sonography allowed a reliable diagnosis of the cystic or solid nature of soft-tissue tumors, an accurate estimation of their volume and their precise three-dimensional localization. Sonography facilitates the location of foreign bodies, and appears as a new promising technique for the evaluation of tendons.

[Echographic imaging of the prostate].

Progress in prostatic ultrasonography has been dramatic during the last decade, due to constant improvements in ultrasound equipment. Several ultrasonic approaches (suprapubic, perineal, transrectal or trans-urethral) are now available. The author reports its own examination technique which combines several approaches and equipments. The normal anatomy of the prostate and seminal vesicles is described, and the benefits of this new imaging method in prostatic pathology are reviewed. The size of the prostate can be accurately measured by ultrasound. The ultrasonographic patterns of benign prostatic hypertrophy, cancer, prostatitis and lithiases are described and diagnostic ambiguities are mentioned. The lack of specificity of the method is obviated by new techniques of ultrasound guided transperineal biopsy. Transrectal ultrasonography has proved effective in the assessment of local cancer invasion. The urodynamic repercussions of prostatic diseases can also be evaluated by ultrasound. Finally, this safe and harmless method should be used to evaluate the response of prostatic carcinomas to conservative treatments.

[Prostatic cancer: role of echography in the diagnosis, evaluation and surveillance].

The author reviews the latest technical improvements, the benefits and limitations of prostatic sonography in the evaluation and follow-up of prostatic cancer. Emphasis is put on the optimal cost/risks/information ratio of transrectal scanning, the accuracy of real-time ultrasound guided transperineal prostatic biopsies and the basic role of transrectal sonography in monitoring the response to treatment.

[Echographic aspects of superficial lipoma].

The author analyzes the sonographic patterns of 14 superficial benign lipomas. Echogenicity ranges from hypoechogenicity with distal sound enhancement to isoechogenicity with the possibility of hyperechoic areas. 50% of the lipomas of this series were ill-defined from the surrounding fatty soft-tissues.

[Diagnosis of calcification of the patellar tendon. Echo-radiographic comparison].

Real-time sonography was compared to low-kilovoltage radiographs in the diagnosis of intra-tendinous calcifications in 10 patients with chronic patellar tendonitis. In these patients sonography demonstrated thickening (100% of cases) and hypoechogenicity (90% of cases) of the patellar tendon. Ultrasound disclosed all calcifications displayed on radiographs showing hyperechoic foci. The associated acoustic shadow was absent in one case of a calcification less than one millimeter in diameter. Real-time ultrasound appears highly reliable in the diagnosis of even minute intra-tendinous calcifications. It also provides an accurate three-dimensional localization of the calcific deposits in the tendons.

[Endorectal echography of the prostate. Comparison of radial and linear type probes].

Prostatic sonography is now routinely performed. Transrectal scanning provides the best imaging quality. Two different types of probes are available: radial probes for transverse scans and linear array probes for longitudinal scans. A comparative study of both types of probes has been performed in 98 patients. Complementary roles of radial and linear probes are demonstrated and the consecutive use of both probes is recommended for a complete sonographic study of prostate and surrounding structures.

[Contribution of ultrasonics in the evaluation of abdominal tumors in children].

Twenty-eight children with abdominal tumors were examined ultrasonically. Real-time ultrasonography proved particularly useful in infants. In most cases ultrasonography shortened the diagnostic procedure by giving accurate images of the tumor's limits, size, contents, and origin. The method yielded an overall diagnostic accuracy rate of 89%. Moreover, ultrasonography is a reliable and safe means of monitoring abdominal tumors during and after therapy. In 1981, plain roentgenograms, intravenous urography with cavography and ultrasonography should be sufficient in the standard radiologic approach of most children with abdominal tumors.

[A new technic of transperineal puncture of the prostate guided by real-time endorectal echography].

The author reports a technique of ultrasonically-guided prostatic biopsy using a new transrectal linear array real-time transducer. The needle is inserted transperineally parallel to the probe towards the prostatic suspicious abnormalities disclosed by transrectal sonography. The needle is entirely visualized and its progression is accurately and safely monitored by a permanent real-time control.

[Ultrasonographic assessment of traumatic muscle injuries in athletes (author's transl)].

In the absence of reliable objective methods to assess traumatic muscle injuries in athletes, the authors have chosen to perform routine ultrasonography. Taking the thigh as an example, they describe the appearance of normal muscles on ultrasonographic images and compare these with CT sections. The results of examination in 61 athletes with traumatic injury are reported. The different ultrasonic patterns are described and compared with surgical findings in 16 cases. All lesions could be detected by ultrasonography, and 87% were correctly identified. Ultrasonography provides direct and clear imaging of the muscles. It constitutes an excellent means of detecting severe lesions and locating them accurately before surgical repair. It is highly reliable and deserves to be adopted by all physicians and surgeons specialized in sports medicine.

[Male genitourinary ultrasound studies (MGUUS) (author's transl)].

The authors report their experience of male genitourinary ultrasound studies of the anterior pelvis over a period of 4 years and involving almost 500 patients. The authors first used a classical ultrasound apparatus in real-time via an anterior abdominal approach. They now have an Aloka mode B apparatus in real-time which by use of three approaches (anterior abdominal, rectal and urethral) offers the possibility of analysis of the male anterior pelvis with four planes of section: 1 sagittal and 3 transverse. Thus MGUUS provides 12 views of the male pelvis. The authors define the techniques used in the light of their experience with this apparatus. They then describe the normal ultrasound anatomy of the male anterior pelvis. Finally, they present their results in pathology with this technique. These results have been obtained in benign and malignant prostatic pathology, everyday routine, longitudinal analyses before and after treatment: surgery, radiotherapy and medical. The results are promising in more recent indications: tumours of the bladder, endocrine andrology, pathology of fertility and in the investigation of the pathological scrotum. Implantation of MGUUS at the centre of technical approaches in urology is felt by the authors to be a necessity, making possible the rational and economic use of the apparatus for both in- and out-patients and the cost of an ultrasound apparatus for every hospital department of urology would appear to be reasonable.
