Fecal incontinence and the anorectal angle
The Netherlands Journal of Surgery
|February 1, 1984
Summary
Fecal incontinence is linked to pelvic floor muscle weakness, indicated by a wider anorectal angle and lower anal resting pressure. Pudendal nerve injury is a likely cause of this condition.
Area of Science:
- Gastroenterology
- Pelvic Health
- Neurology
Background:
- Fecal incontinence affects many individuals, significantly impacting quality of life.
- The pelvic floor musculature plays a crucial role in maintaining fecal continence.
- Understanding the biomechanical factors associated with fecal incontinence is essential for effective treatment.
Purpose of the Study:
- To investigate the relationship between pelvic floor muscle activity and fecal incontinence.
- To compare the anorectal angle and anal resting pressure in patients with and without fecal incontinence.
Main Methods:
- Twenty-five patients were studied, with nine diagnosed with fecal incontinence.
- Measurements included anorectal angle and anal resting pressure.
- Anal sensation and maximal squeeze pressure were also considered.
Main Results:
- A decrease in anal resting pressure correlated with an increase in the anorectal angle.
- Impaired fecal control was associated with diminished pelvic floor muscle activity.
- Patients with fecal incontinence exhibited reduced anal sensation and maximal squeeze pressure.
Conclusions:
- Diminished pelvic floor muscle activity, evidenced by increased anorectal angle and reduced anal pressure, is associated with fecal incontinence.
- Pudendal nerve injury is a probable cause of fecal incontinence, contributing to impaired sensation and muscle function.

01:19Abdominal Regions and Quadrants
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four quadrants...

01:26Muscles of the Pelvic Floor and Perineum
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:21Inflammatory Bowel Disease V: Surgical Management
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

01:26Psychosexual Stages of Personality: Anal
Sigmund Freud's theory of psychosexual development describes the anal stage as occurring between 18 months and three years of age. During this period, children derive pleasure from controlling and releasing their bowel movements. However, they quickly learn that societal expectations impose restrictions on when and where this can happen. This stage marks a critical point where children begin to develop a sense of control and mastery over their bodily functions, as well as their broader...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
