A colonoscopy through stoma is a specialized procedure that involves the examination of the colon via an existing stoma, such as a colostomy. During this procedure, an endoscope is inserted through the stoma to visualize the mucosal surfaces of the colon, extending from the stoma to the cecum or a small intestine anastomosis. The primary objective is to inspect for any abnormalities, including tumors, polyps, or other lesions. As the endoscope is withdrawn, the entire circumference of the colon is thoroughly examined to identify any pathological findings. If any lesions are detected, they can be removed using a snare technique. This technique involves placing a wire snare loop around the lesion, which is then heated to excise and cauterize the tissue. The lesion may be removed in one piece (en bloc) or in smaller fragments (piecemeal), depending on its size and characteristics. This procedure is crucial for managing colorectal conditions and ensuring the health of patients with stomas.
