Ileoscopy is a specialized endoscopic procedure that involves the examination of the ileum, which is the final section of the small intestine, through an existing stoma, specifically an ileostomy. This procedure is performed using an endoscope, a flexible tube equipped with a camera and light source, which is inserted into the ileum via the stoma. The primary purpose of ileoscopy is to visualize the mucosal lining of the ileum, allowing for the assessment of any abnormalities or conditions affecting this part of the digestive tract. During the procedure, the ileum is inflated with a small amount of air to expand the mucosal folds, enhancing visibility for the physician. This inflation aids in the thorough inspection of the mucosa for any signs of disease or damage. Additionally, ileoscopy can involve obtaining tissue samples through biopsy or collecting cell samples via brushing or washing techniques. A critical component of this procedure is the transendoscopic balloon dilation, which is performed when a narrowed area, or stricture, of the ileum is identified. This dilation process involves the use of a balloon device that is inserted through the endoscope to widen the narrowed segment, thereby improving the passage through the ileum. The combination of these techniques during ileoscopy allows for both diagnostic and therapeutic interventions, making it a valuable procedure in managing conditions affecting the ileum.
