Summary
Dyssynergic defecation, a common cause of constipation resistant to standard treatments, involves muscle coordination issues during bowel movements. This review covers its diagnosis, evaluation, and management, including new therapies like biofeedback and neuromodulation.
Area of Science:
- Gastroenterology
- Pelvic Floor Disorders
- Digestive Health
Background:
- Constipation refractory to lifestyle changes and laxatives often requires specialist referral.
- Dyssynergic defecation, a primary cause of refractory constipation, involves impaired coordination of the rectoanal, abdominal, and pelvic floor muscles during defecation.
- Effective management necessitates a thorough understanding of diagnosis, evaluation, and treatment strategies for evacuation disorders.
Purpose of the Study:
- To provide a comprehensive overview of dyssynergic defecation and other evacuation disorders.
- To detail the definition, pathophysiology, diagnostic methods, and therapeutic options for these conditions.
- To highlight emerging treatments for refractory constipation and related pelvic floor dysfunction.
Main Methods:
- This is a review article synthesizing current knowledge on dyssynergic defecation.
- Information was gathered on the pathophysiology, diagnosis, and treatment of evacuation disorders.
- Focus is placed on established and novel therapeutic interventions.
Main Results:
- Dyssynergic defecation is a key contributor to chronic constipation unresponsive to conventional therapies.
- Evaluation involves assessing rectoanal, abdominal, and pelvic floor muscle coordination.
- Emerging treatments show promise for specific conditions like dyssynergic defecation and levator ani syndrome.
Conclusions:
- Understanding and diagnosing dyssynergic defecation are crucial for managing patients with refractory constipation.
- A range of treatments, from behavioral therapies to neuromodulation, are available.
- New therapeutic avenues offer hope for improved patient outcomes in evacuation disorders.

01:17Drugs for Treatment of Diarrhea-Predominant IBS
343
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

01:26Feces Formation and Defecation
1.8K
After spending 3 to 10 hours in the large intestine, chyme loses a lot of water and becomes feces, the final product of digestion. Feces consist of undigested dietary fiber such as cellulose, mucus, sloughed-off epithelial cells, and microbes. The descending and sigmoid colon stores feces and uses haustral contractions to dry it out but retains enough water to give it a semi-solid texture.

01:20Gastrointestinal Motility Disorders
641
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...

01:20Drugs Affecting GI Tract Motility: Other Laxatives
534
Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...

01:26Physiology of the Gastrointestinal System III: Elimination
582
The gastrointestinal elimination process involves a complex interplay of neural and hormonal mechanisms that coordinate the final waste removal from the body. This intricate operation encompasses the absorption of water and electrolytes, vital for transforming the remaining indigestible food matter into feces. The large intestine is pivotal in water and electrolyte absorption, forming feces from unabsorbed minerals, undigested food, bacteria, bile pigments, and shed epithelial cells. Essential...
