A colonoscopy through a stoma is a specialized procedure that involves the examination of the colon via an existing stoma, such as a colostomy. This procedure is performed using an endoscope, which is a flexible tube equipped with a camera and light source, allowing for direct visualization of the mucosal surfaces of the colon. The examination extends from the stoma to the cecum or a small intestine anastomosis, enabling healthcare professionals to inspect for any abnormalities, such as lesions, ulcerations, or strictures. During the procedure, if a mucosal lesion is identified, directed submucosal injections may be administered. These injections serve multiple purposes, including marking the lesion for better visualization or creating a submucosal fluid cushion to facilitate the removal of the lesion. Common substances used for these injections include India ink, botulinum toxin, saline, epinephrine, or corticosteroids. The procedure is crucial for diagnosing and managing various gastrointestinal conditions, ensuring that any abnormalities are thoroughly evaluated and treated as necessary.
