Abstract:
Pelvic floor abnormalities often impact significantly the quality of life and result in a variety of symptoms, including chronic pelvic pain, fecal incontinence, and obstructed constipation. Fluoroscopic defecography and MR defecography enable identification of rectocele, rectal prolapse, enterocele, sigmoidocele with high prevalence in female patients with obstructed constipation, fecal incontinence, and chronic pelvic pain. In this manuscript, we describe the techniques and indications of the two techniques of defecography. We discuss the abnormalities of the posterior pelvic floor compartment at the origin of constipation, incontinence, chronic pelvic pain. Finally we compare the data obtained by clinical examination and defecography, remembering that 50% of enterocele and 100% of sigmoidocele are missed at clinical examination.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
