“…Considering the rectum's average length ranges from 12 to 15 cm, the probe may be safely advanced up to 10 to 12 cm, at about the superior Houston valve. (13) Posteriorly, the bony structure of the sacrum, mostly at S3 level, is identified as a landmark behind the rectum (Fig. 6A).…”

“…Sonographic definition of anal canal refers to the "surgical" or "functional" anal canal, which is from the anal verge to the anorectal ring. (13) The squamous-columnar junction, the mucocutaneous transition from the anoderm to the mucous membrane of the rectum, lies at the inner most layer. Then, a complex arrangement of multiple muscle layers compiled as a cylindrical structure, with the subsequent layers of internal sphincter, the intersphincteric space with the longitudinal muscle fibers running down, and the outer striated skeletal muscle layers of external sphincter and puborectalis muscle.…”

Endoluminal ultrasound has become a cornerstone for evaluating anorectal diseases since its introduction as a diagnostic tool nearly three decades ago. This article reviews the applications of 3-dimensional (3D) endoluminal ultrasound, including transrectal (TRUS) and transanal (TAUS), in clinical settings and highlights their efficacies for diagnosing various anorectal conditions. Technological advancements, such as high-resolution imaging and multiplanar display capabilities, enable detailed assessments of anatomic structures, but high-quality images are required to standardize preprocedural and intraprocedural protocols and ensure patient comfort. This article provides insight into examination methodologies, especially those utilizing sophisticated multifrequency transducers that produce in-depth 2D and 3D images. Fundamental anatomical reference points are noted, and the diagnostic importance of understanding rectal wall layers, vasculature, and muscular structures is emphasized. This comprehensive review underscores the importance of standardizing procedures to improve the consistency and reliability of 3D endoluminal ultrasound for diagnosing anorectal diseases.

A prerequisite for nerve-sparing pelvic surgery is a thorough understanding of the topographic anatomy of the fine and intricate pelvic nerve networks, and their connections to the central nervous system. Insights into the functions of pelvic nerves will help to interpret disease symptoms correctly and improve treatment. In this article, we review the anatomy and physiology of autonomic pelvic nerves, including their topography and putative functions. The aim is to achieve a better understanding of the mechanisms of pelvic pain and functional disorders, as well as improve their diagnosis and treatment. The information will also serve as a basis for counseling patients with chronic illnesses. A profound understanding of pelvic neuroanatomy will permit complex surgery in the pelvis without relevant nerve injury.
