Summary
Many patients with slow-transit constipation exhibit generalized gut motor disorders. This study investigated antroduodenal motor activity in these patients to understand underlying causes.
Area of Science:
- Gastroenterology
- Digestive System Physiology
- Motility Disorders
Background:
- Subtotal colectomy outcomes for slow-transit constipation are often unpredictable.
- Persistent abdominal pain, distension, and bloating are common post-surgery.
- Investigating generalized intestinal motor disorders in slow-transit constipation is crucial.
Purpose of the Study:
- To determine if slow-transit constipation patients have generalized intestinal motor disorders.
- To study antroduodenal motor activity in patients with slow-transit constipation.
Main Methods:
- 20 patients with slow-transit constipation underwent comprehensive constipation characterization.
- Methods included symptom registration, whole-gut transit time, anorectal manometry, electromyography, balloon expulsion test, and defecography.
- Antroduodenal motor activity was monitored for 5 hours using a pneumohydraulic manometry system.
Main Results:
- 60% of patients (12/20) displayed abnormal motor activity patterns.
- Abnormalities included disrupted phase III activity, non-propagated phasic activity, and intense phasic activity.
- Discrete clustered contractions were observed in 6 patients; one showed generalized hypomotility.
Conclusions:
- A significant number of slow-transit constipation patients present with manometric evidence of a generalized gut motor disorder.
- The precise clinical significance of these generalized motor findings remains to be elucidated.

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.

01:26Imaging 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...

01:23Lower GI Series: Barium Enema
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...
