Summary
This pictorial essay reviews uncommon causes of small bowel obstruction, a frequent clinical issue. It highlights key radiological findings and proposes a diagnostic algorithm for better patient care.
Area of Science:
- Radiology
- Gastroenterology
- Surgical Pathology
Background:
- Small bowel obstruction is a common clinical diagnosis, frequently affecting the small intestine.
- While postoperative adhesions cause 60% of cases, other common etiologies include hernias, strangulation, and tumors like carcinoid, lymphoma, and adenocarcinoma.
Purpose of the Study:
- To present the radiological findings of rare causes of small bowel obstruction.
- To propose a diagnostic algorithm for managing uncommon small bowel obstruction.
Main Methods:
- Pictorial essay format.
- Review of radiological findings associated with uncommon small bowel obstruction etiologies.
- Development of a diagnostic algorithm.
Main Results:
- Detailed radiological appearances of various uncommon small bowel obstruction causes are illustrated.
- A structured diagnostic pathway is suggested for clinical application.
Conclusions:
- Recognizing uncommon causes of small bowel obstruction through characteristic radiological findings is crucial.
- A systematic diagnostic approach aids in timely and accurate diagnosis, improving patient outcomes.

01:29Intestinal Obstruction I: Introduction
Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
01:29Appendicitis-II: Diagnostic Studies and Management
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

01:21Inflammatory Bowel Disease V: Surgical Management
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

01:07Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
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...
