A flexible colonoscopy is a diagnostic and therapeutic procedure that involves the insertion of a colonoscope into the rectum and advancement through the colon to the cecum or the terminal ileum. This procedure is specifically performed for the removal of foreign body(s) that may be lodged within the colon. During the colonoscopy, air insufflation is utilized to expand the colon, allowing for improved visualization of the mucosal surfaces. The physician inspects these surfaces meticulously to locate the foreign body. Various techniques may be employed for the removal of the foreign body, including the use of a balloon catheter for smooth-edged objects or forceps for impacted items. The balloon catheter technique involves passing the catheter tip beyond the foreign body, inflating the balloon, and then withdrawing the catheter to extract the foreign body. In cases where the foreign body is impacted, forceps are introduced through the endoscope to grasp and remove the object. After the removal process, the colonoscope is reintroduced to conduct a thorough examination of the colon for any signs of perforation or other potential injuries that may have occurred during the procedure.
