Functional Anorectal Disorders
Gastroenterology
|May 5, 2016
Summary
This review outlines criteria for fecal incontinence (FI), functional anorectal pain, and defecation disorders. Management includes biofeedback therapy, with surgery for severe cases.
Area of Science:
- Gastroenterology and Colorectal Surgery
Background:
- Common anorectal disorders include fecal incontinence (FI), functional anorectal pain, and functional defecation disorders.
- Understanding their epidemiology, pathophysiology, and management is crucial for effective patient care.
Purpose of the Study:
- To define diagnostic criteria for these anorectal disorders.
- To review current management strategies, including conservative and surgical options.
Main Methods:
- Literature review and synthesis of existing data on anorectal disorders.
- Definition of diagnostic criteria based on clinical features, manometry, and imaging.
Main Results:
- Fecal incontinence (FI) is defined by recurrent uncontrolled fecal passage.
- Functional anorectal pain includes subtypes like proctalgia fugax and levator ani syndrome (LAS).
- Functional defecation disorders involve impaired evacuation, with subtypes like dyssynergic defecation.
Conclusions:
- Anorectal manometry and imaging aid in evaluating anal and pelvic floor function.
- Biofeedback therapy is a primary treatment for LAS and defecatory disorders.
- Education, antidiarrheals, and biofeedback are mainstays; surgery is reserved for refractory cases.

01:25Assessment of the Rectum and Anus
1.7K
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.

01:20Gastrointestinal Motility Disorders
1.5K
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

1.4K
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

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.
