Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

1.0K
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 IBS

670
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

975
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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

722
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

503
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Area of Science:

  • Critical Care Medicine
  • Gastroenterology
  • Clinical Pathophysiology

Background:

  • Constipation is a frequent, underdiagnosed issue in critically ill adults.
  • It significantly affects patient morbidity, hospital length of stay, and overall prognosis.
  • Challenges in diagnosis arise from varied presentations and lack of standardized criteria.

Purpose of the Study:

  • To review the current understanding of constipation in critical care.
  • To examine contributing factors and management strategies for critically ill adults.
  • To highlight the need for early detection and research.

Main Methods:

  • This is a narrative review.
  • It synthesizes current knowledge on constipation in the intensive care unit setting.
  • It discusses contributing factors, diagnostic challenges, and therapeutic approaches.

Main Results:

  • Constipation in critical care is multifactorial, influenced by immobility, medications, and critical illness itself.
  • Standardized diagnostic criteria are lacking, complicating identification.
  • Both pharmacologic and non-pharmacologic interventions are discussed.

Conclusions:

  • Constipation significantly impacts critically ill patients and requires greater clinical attention.
  • Early identification and tailored management are essential for better patient outcomes.
  • Further prospective research is needed to establish evidence-based guidelines.
