Insights

Functional constipation in children shows abnormal anorectal motility, specifically in minimal sensitivity and maximal tolerated volume. Management guided by anorectal manometry proved effective for most patients.

Area of Science:

  • Pediatric Gastroenterology
  • Motility Disorders

Background:

  • Functional constipation is a prevalent pediatric condition.
  • Anorectal manometry is a key diagnostic tool.

Purpose of the Study:

  • Investigate anorectal motility in children with functional constipation.
  • Compare motility with healthy children.
  • Evaluate management efficacy based on manometry.

Main Methods:

  • Multi-functional manometry used on 18 children (8 with functional constipation, 10 healthy).
  • Patients received probiotics, prebiotics, and scheduled defecation.
  • Treatment efficacy assessed during follow-up.

Main Results:

  • No significant differences in anal sphincter length or pressure.
  • Significant differences found in minimal sensitivity and maximal tolerated volume.
  • Seven of eight patients improved with conservative treatment.

Conclusions:

  • Children with functional constipation exhibit anorectal motility abnormalities.
  • Conservative treatment tailored by anorectal manometry is effective.

Assessment of the Rectum and Anus01:25

Assessment 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.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...
Drugs for Treatment of Constipation-Predominant IBS01:21

Drugs 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...

Drugs Affecting GI Tract Motility: Other Laxatives

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...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

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 solid...
Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

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...
Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives01:22

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

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 makes...
