Anorectal conditions: fecal incontinence

Area of Science:

• Gastroenterology
• Urology
• Geriatrics

Background:

• Fecal incontinence (FI) is prevalent across all age groups but disproportionately affects older adults, particularly women and nursing home residents.
• Often co-occurring with urinary incontinence, FI stems from diverse etiologies including trauma, surgery, childbirth, radiation, disease, neurologic conditions, medications, and functional impairments.

Purpose of the Study:

• To outline the comprehensive evaluation and management strategies for fecal incontinence.
• To detail diagnostic approaches and therapeutic interventions for various etiologies of fecal incontinence.

Main Methods:

• Initial evaluation focuses on identifying underlying causes and assessing severity using scoring systems.
• Conservative treatments include dietary modifications, antidiarrheal agents, management of fecal impaction, and biofeedback.
• Advanced diagnostic tests such as endorectal ultrasound, anorectal manometry, and pudendal nerve terminal motor latency testing are employed when conservative measures fail.

Main Results:

• Conservative measures form the first line of treatment for fecal incontinence.
• Further investigations help characterize specific sphincter defects or functional impairments.
• A range of surgical and interventional options exist for refractory cases, including sphincter repair, bulking agents, sacral neuromodulation, and ostomy creation.

Conclusions:

• Effective management of fecal incontinence requires a stepwise approach, starting with conservative measures and progressing to advanced diagnostics and interventions as needed.
• The goal of treatment is to identify and address etiologies, improve symptom control, and enhance the patient's quality of life.
