Inflammatory Bowel Disease II: Crohn's Disease01:30

Inflammatory Bowel Disease II: Crohn's Disease

952
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

746
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...

Inflammatory Bowel Disease I: Ulcerative Colitis

894
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

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

637
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...

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

1.1K
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,...

Summary

Small bowel diverticula (SBD) are often overlooked but can cause serious complications. Endoscopic methods significantly improve jejunoileal SBD diagnosis compared to radiology, increasing clinical awareness.

Area of Science:

  • Gastroenterology
  • Surgical Gastroenterology
  • Diagnostic Imaging

Background:

  • Small bowel diverticulum (SBD) is an outpouching of the small intestinal wall, often neglected due to its location.
  • While frequently asymptomatic, SBD can lead to life-threatening complications requiring clinical attention.

Purpose of the Study:

  • To investigate the clinical characteristics and diagnostic modalities associated with small bowel diverticula.
  • To compare diagnostic accuracy between endoscopic and radiological methods for SBD detection.

Main Methods:

  • A retrospective case series analyzing clinical data from 149 patients across two tertiary referral centers.
  • Systematic collection and review of baseline characteristics, clinical presentation, diagnostic methods, and treatment.
  • Subgroup analysis based on SBD location (duodenum, jejunum, ileum).

Main Results:

  • Of 149 SBD cases, duodenal SBD (n=114) were often asymptomatic (36.8%) or presented with pain (50.9%).
  • Jejunoileal SBD (n=35) were predominantly symptomatic, with 60% requiring surgery for obstruction, bleeding, or perforation.
  • Endoscopic modalities (DBE/VCE) showed 92.3% diagnostic accuracy for jejunoileal SBD, significantly outperforming radiology (38.5%, p<0.001).

Conclusions:

  • Small bowel diverticular disease is under-recognized due to its location and diagnostic challenges.
  • Advancements in endoscopic techniques are expected to increase SBD detection rates and clinical awareness among gastroenterologists.
