The patient was a 68-year-old male, who had inserted a melon into his anus for the purpose of masturbation, and was unable to discharge it . Abdominal CT showed the melon measuring 16 cm ×7cm at the level of the rectosigmoid and no obvious intestinal perforation. We considered that the rectum could be damaged at the time of extraction, and attempted extraction under general anesthesia. The surgery was started with the patient in the lithotomy position. Although relaxation of the anal sphincter was obtained, the foreign body could not be visualized from the anus. The top of the melon was slightly observed when the lower abdomen was pressed. It was difficult to grasp it with a Muzeaux uterine tenaculum forceps, therefore, we inserted a Myoma borer into the melon in an attempt to retrieve it. However, because the melon was fragile, the inserted part of the Myoma borer broke. By inserting another one from another angle, we were able to disperse the power and compensate for the vulnerability, and succeeded in excising the foreign body, while also using abdominal compression. A wide variety of foreign bodies have been reported as rectal foreign bodies, and it is necessary to devise individual methods to removing them. We report a case of successful removal of a rectal foreign body (melon) using Myoma borers.
