A colonoscopy through stoma is a specialized medical procedure that involves the examination of the colon via an existing stoma, such as a colostomy. This procedure is specifically designed for the removal of foreign bodies that may have become lodged within the colon. During the colonoscopy, a colonoscope—a flexible tube equipped with a camera and light—is inserted through the stoma and advanced through the colon until it reaches the location of the foreign body. The procedure may utilize a balloon catheter to facilitate the removal of smooth-edged foreign objects. In this case, the catheter is maneuvered past the foreign body, and once positioned correctly, the balloon is inflated to help dislodge the object. After inflation, the catheter is carefully withdrawn, pulling the foreign body out of the colon. For more challenging cases where the foreign body is impacted, forceps are employed. These forceps are introduced through the endoscope, allowing the physician to grasp the impacted object securely and remove it from the colon. After the successful extraction of the foreign body or bodies, the colonoscope is reinserted to conduct a thorough examination of the colon for any signs of perforation or other potential injuries that may have occurred during the procedure.
