Drugs for Treatment of Constipation-Predominant IBS01:21

Drugs for Treatment of Constipation-Predominant IBS

154
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...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy01:26

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

72
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

193
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.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Irritable Bowel Syndrome II: Clinical Features and Diagnostic Evaluation
Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:

Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives

199
Laxatives enhance bowel movements and alleviate constipation. They augment the stool's bulk, stimulate intestinal muscle contractions, draw water into the intestines, or soften the stool. There are five key types of laxatives: bulk laxatives, stimulant laxatives, osmotic laxatives, stool softeners, and lubricant laxatives.
Bulk-forming laxatives, such as psyllium, methylcellulose, and polycarbophil, absorb water in the intestine, increasing stool bulk and promoting bowel movement. This...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy01:30

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

331
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Summary

Diagnostic studies for pediatric constipation are reviewed. Colon transit studies, colon scintigraphy, MRI, and anorectal manometry help identify causes in children unresponsive to conventional therapy.

Area of Science:

  • Pediatric Gastroenterology
  • Diagnostic Imaging
  • Functional Bowel Disorders

Background:

  • Constipation is a frequent reason for pediatric gastroenterology consultations.
  • Most children improve with lifestyle changes and conventional treatments.
  • Some cases necessitate further diagnostic evaluation.

Purpose of the Study:

  • To review diagnostic studies for evaluating functional constipation in children.
  • To guide the appropriate use of investigations in pediatric constipation.

Main Methods:

  • Review of diagnostic modalities including colon transit studies (radiopaque markers or scintigraphy), MRI, and manometry.
  • Discussion of indications for each diagnostic tool.
  • Exclusion of routine abdominal X-rays.

Main Results:

  • Colon transit studies are useful when clinical history is inconsistent or to guide manometry.
  • Anorectal manometry assesses rectal function and recto-anal inhibitory reflex.
  • MRI is indicated for suspected spinal abnormalities.

Conclusions:

  • Diagnostic studies aim to uncover treatable causes of constipation.
  • These investigations evaluate colonic/rectal anatomy, transit, and motility.
  • Indications are primarily for patients refractory to standard treatments.
