Mr. Wang, 40, came to the clinic with a painful expression and complained of “anal pain”, which was aggravated by walking, coughing, laughing, and bumps in the car. After an anal finger examination, it was found that a fish spike or a bone like object was suspected to be stuck in the anal sinus, so the foreign body was removed under local anesthesia and the diagnosis was confirmed as fish spike impaction. Do not gobble or gulp down your food to avoid “chrysanthemum” injury, or even “chrysanthemum” disability. Anorectal foreign body residue or embedment is also one of the common emergencies in anorectal medicine. Common foreign bodies are swallowed (chicken bones, fish bones, fish spines, melon seeds, date kernels, denture, etc.), inserted through the anus (radish, bottles, erotic products, etc.), or huge fecal stones, gallstones, etc. Some foreign bodies remain in the physiological stenosis or bend of the intestine and are difficult to be discharged, causing local intestinal stab wounds, which may lead to intestinal perforation. Some foreign body residues block the intestinal cavity, resulting in fecal matter cannot be discharged and causing low intestinal obstruction. Therefore, it is recommended that patients do not swallow dates and swallow date pits, coins, bones, fish spines and other foreign bodies, and eat more coarse fiber food to wrap foreign bodies to facilitate their discharge from the anus. When using erotic products, choose scientifically designed safety products to avoid foreign bodies slipping into the rectum and difficult to remove. Once you find a foreign body swallowed into the digestive tract or slipped into the rectum, or have pain and other discomfort in the anus, go to the hospital in a timely manner.
