VISUOG is a comprehensive visual encyclopedia for ultrasound in obstetrics & gynecology. Detailed anatomical visualisations, case studies and expert commentary have collectively contributed to enhancing clinical decision-making and diagnostic accuracy.

Endometriosis, characterised by the abnormal growth of endometrial-like cells outside the uterus, is a highly prevalent and debilitating whole-body disease. Among the three primary phenotypes of endometriosis, deep endometriosis (DE) stands out as the most severe form, marked by the infiltration of abnormal growth into the fibromuscular tissue. Unfortunately, it's noteworthy that 20-70% of individuals diagnosed with DE have DE of the uterosacral ligaments (USLs).

While there has historically been a reliance on surgical visualization and a detailed clinical history to diagnose most phenotypes of endometriosis, recent advancements in non-invasive diagnostics, particularly transvaginal ultrasound (TVS), have enhanced the diagnostic performance. The chapter offers the chance to learn more about transvaginal ultrasound (TVS) as a non-invasive diagnostic tool for endometriosis, including its application in assessing deep endometriosis (DE) of uterosacral ligaments (USLs).

This chapter, available for free throughout March, aims to provide a nuanced understanding of DE of the USLs, covering clinical manifestations, a comprehensive diagnostic overview, and contemporary treatment approaches. Additionally, the chapter provides details on the etiology and pathology of endometriosis. Furthermore, it delves into the management strategies for deep endometriosis (DE) of the uterosacral ligaments (USLs).

By examining the intricacies of diagnostic challenges and exploring innovative methodologies, this chapter offers a thorough synthesis of the present understanding of deep endometriosis (DE) involving the uterosacral ligaments (USLs).
