Summary
A rare complication of barium sulphate contrast radiography in a cat led to gastrointestinal obstruction. Surgical removal of affected tissue resolved the cat's chronic vomiting and weight loss.
Area of Science:
- Veterinary Medicine
- Gastroenterology
- Diagnostic Imaging
Background:
- Barium sulphate contrast radiography is a common diagnostic tool in veterinary medicine.
- Complications, though rare, can occur following barium studies.
Observation:
- A cat presented with chronic vomiting, anorexia, and weight loss two months after a barium study.
- Imaging revealed small intestinal obstruction with residual contrast enhancement.
Findings:
- Exploratory laparotomy identified and resected a stenosed ileum and jejunum.
- Histopathology revealed barium sulphate crystals within the gastrointestinal mucosa, causing ulceration and granulation tissue formation.
Implications:
- This case highlights a rare but serious complication of barium sulphate administration.
- It underscores the importance of considering iatrogenic causes for gastrointestinal signs post-radiography.

01:24Upper GI Series: Barium Swallow
2.2K
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.

2.3K
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...

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
587
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...

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

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.
