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: 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...
Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
Drugs Affecting GI Tract Motility: Other Laxatives01:20

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...

Area of Science:

  • Gastroenterology
  • Evidence-Based Medicine

Background:

  • Constipation diagnosis can be subjective, differing from rigid criteria.
  • Constipation is a common condition, evidenced by millions of laxative prescriptions annually.

Purpose of the Study:

  • To systematically review the effects of non-drug and other interventions for idiopathic chronic constipation in adults.

Main Methods:

  • Conducted a systematic literature search up to October 2006 across major databases.
  • Included 42 systematic reviews, randomized controlled trials (RCTs), and observational studies.
  • Performed GRADE evaluation for the quality of evidence.

Main Results:

  • Identified a wide range of interventions for idiopathic chronic constipation.
  • Evidence quality was evaluated using the GRADE system.

Conclusions:

  • Presents information on the effectiveness and safety of numerous interventions.
  • Interventions reviewed include dietary fiber, increased fluid intake, exercise, biofeedback, and various pharmacological agents like lactulose, macrogols, and senna.
