Anoscopy with removal of a foreign body is a medical procedure that involves the visual inspection of the anus and rectum to identify and extract an object that has become lodged within the rectal cavity. This procedure typically begins with a digital rectal examination, which may be performed to assess the area and locate the foreign body. An anoscope, a tubular instrument designed for viewing the anal canal and lower rectum, is then utilized. The obturator, a device that facilitates the insertion of the anoscope, is placed into the scope before it is introduced into the anus. Once the anoscope is positioned at the site of the foreign body, the obturator is removed, and an eyepiece is attached to allow for direct visualization. In cases where the foreign body has smooth edges, a balloon catheter may be employed to assist in its removal. The catheter is advanced past the foreign body, and the balloon is inflated to create a seal around the object, allowing for its withdrawal. For more firmly impacted foreign bodies, forceps are used. These are passed through the endoscope to grasp the object securely before it is extracted. After the foreign body is removed, the endoscope is reinserted to conduct a thorough examination of the rectum, checking for any signs of perforation or injury that may have occurred during the process. This procedure is essential for addressing rectal obstructions and ensuring the integrity of the rectal wall following the removal of foreign objects.
