“…Curved linear array echoendoscopes use an electronic transducer and they offer the ability to perform interventional procedures such as FNA under real-time visualization [6]. New techniques that have contributed significantly to the evolution of ERUS include three-dimensional ERUS [7], high-frequency miniprobes, transrectal ultrasound-guided biopsy techniques, and hydrogen peroxide-enhanced endosonography [8]. ERUS-FNA is usually well tolerated under conscious sedation on an outpatient basis similar to other endoscopic procedures [6].…”

Objectives: Endorectal endoscopic ultrasound (ERUS) allows highly detailed assessment of the rectal wall layers and visualization of the extraluminal structures. Herein, we study the utility of ERUS fine-needle aspiration (FNA) to evaluate perirectal lesions. Study Design: Forty-nine ERUS-FNAs were retrieved from the cytopathology archives of The Johns Hopkins Hospital. The cytology slides, corresponding histology, immunohistochemistry when available, and clinical data were reviewed. Results: The aspirated material showed malignant (n = 24), benign (n = 19), atypical (n = 3), carcinoid tumor (n = 1), and nondiagnostic conditions (n = 2). The past medical history of 36 cases was significant for carcinomas. The primary site of the tumors included colorectal, urinary bladder, prostate, pancreas, gallbladder, ovary, and female lower genital tract. Statistical analysis for endoscopic ultrasonography FNA showed 87% sensitivity, 100% specificity, diagnostic accuracy of 90%, and a positive predictive value of 100% and a negative predictive value of 77%. Conclusion: ERUS-FNA can be utilized for: (1) accurate staging of colorectal adenocarcinomas by evaluation of nodal metastasis, depth of transmural tumor invasion and local tumor spread to perirectal fat, (2) prevention of aggressive surgical intervention in benign conditions, (3) providing diagnostic material for ancillary studies, and (4) evaluation of perirectal lesions with a more accurate method by combining imaging and histology.

“…[48][49][50][51] Assessment of additional scan planes and volume reconstructions facilitate the understanding of three-dimensional anatomy and improve the evaluation of the depth of tumor invasion. 17 Giovannini et al 50 reported that the mesorectal margins are defined better using threedimensional ERUS than two-dimensional ERUS. In 6 of 15 patients classified as having T3N0 lesions, three-dimensional ERUS revealed malignant lymph nodes, a finding that was confirmed surgically in five of the six cases.…”

Anorectal diseases require imaging for proper case management. At present, endoanal ultrasonography and endorectal ultrasonography have become important parts of diagnostic workup of patients with fecal incontinence, perianal fistulas, and rectal cancer and provides sufficient information for clinical decision-making in many cases. However, with the currently available ultrasonographic equipment and techniques, a good deal of relevant information may remain hidden. The advent of high-resolution three-dimensional endoluminal ultrasound, constructed from a synthesis of standard two-dimensional cross-sectional images, and of "Volume Render Mode," a technique to analyze information inside a three-dimensional volume by digitally enhancing individual voxels, promises to revolutionize diagnosis of pelvic floor disorders. By use of the different postprocessing display parameters, the volume-rendered image provides better visualization performance when there are not large differences in the signal levels of pathologic structures compared with surrounding tissues. The anatomic structures in the pelvis, the axial and longitudinal extension of anal sphincter defects, the anatomy of the fistulous tract in complex perianal sepsis, and the presence of slight or massive submucosal invasion in early rectal cancer may be imaged in greater detail. This additional information will bring an improvement for both planning and conduct of surgical procedures.
