AVALIAÇÃO MORFOFUNCIONAL POR ELETROMANOMETRIA DE ALTA RESOLUÇÃO E ULTRASSONOGRAFIA ANORRETAL DE PACIENTE COM ENDOMETRIOSE PROFUNDA GRAVE
High-resolution manometry and ultrasonography revealed impaired rectal distensibility, reduced propulsive pressure, and paradoxical increases in intra-anal pressure in a patient with severe deep endometriosis.

The paper reports an anatomofunctional assessment of a 30-year-old woman diagnosed with severe deep infiltrating endometriosis involving the rectum, using three-dimensional anorectal ultrasound (US3D) and high-resolution anorectal manometry (HRM). US3D suggested a perirectal endometriotic focus with involvement of the right lateral rectal wall (muscularis propria), while HRM showed normal resting and contractile sphincter tone but reduced rectal propulsive pressure, paradoxical increases in intra-anal pressure, sensory/rectal capacity changes, and findings consistent with anismus/pelvic floor dyssynergia type II, with an intact rectosphincteric reflex and normal functional anal canal. During surgery and videolaparoscopy, rectal lesions extending to the muscular wall and extrinsic compression were identified and confirmed, along with additional endometriosis foci in other pelvic/abdominal sites. This paper is centrally about endometriosis — it specifically evaluates anorectal morphology and function in severe deep endometriosis with rectal involvement, confirmed intraoperatively.
