Summary
Obstructed defecation syndrome (ODS) management requires a multimodal approach. Conservative treatments are primary, with surgery reserved for specific cases, guiding effective clinical practice.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Pelvic Floor Disorders
Background:
- Obstructed defecation syndrome (ODS) is a complex condition impacting quality of life.
- It presents diagnostic and therapeutic challenges due to functional and anatomical factors.
- Effective clinical management strategies are needed.
Purpose of the Study:
- To develop a Belgian consensus on ODS diagnosis and treatment.
- To create a diagnostic-therapeutic algorithm for ODS management.
- To provide practical guidance for clinicians.
Main Methods:
- A Delphi consensus process involving 31 experts.
- Structured literature review and three online voting rounds.
- Consensus defined as ≥80% agreement, with evidence graded by GRADE.
Main Results:
- ODS defined as an anorectal evacuation disorder with coexisting functional and structural components.
- Diagnosis requires multimodal evaluation including physical and anorectal testing.
- Conservative measures (lifestyle, laxatives, pelvic floor re-education) are first-line; surgery is for refractory cases with anatomical abnormalities.
Conclusions:
- Consensus statements offer practical guidance for ODS diagnosis and management.
- Conservative therapy is the cornerstone of ODS treatment.
- Further research is needed for areas lacking consensus.

01:17Drugs for Treatment of Diarrhea-Predominant IBS
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...

01:21Drugs for Treatment of Constipation-Predominant IBS
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
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.

DefinitionIrritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent combinations of abdominal pain, bloating, diarrhea, or constipation.Pathophysiology of irritable bowel syndromeIts pathophysiology is multifactorial, involving disturbances in motility, sensory processing, microbial balance, barrier integrity, and gut–brain communication. These mechanisms interact to produce symptoms that vary across IBS subtypes.Altered Motility PatternsDisordered...
