A Chinese man recently found himself having a 10-inch long cylindrical object stuck in his rectum and had to go through a two-hour operation to have it removed.

Doctors in a hospital in Guangzhou, southern China, were surprised to see a microphone-shaped item lodged in the man's colon after an X-ray, reported People's Daily Online.

The patient refused to explain how the object had got there, but media reports suggest the man had been involved in a fight at a karaoke bar when the object was inserted into his body.

The 10 inch long cylindrical object was captured on X-ray and had been lodged for 27 hours before operation

The middle-aged man, named only by his surname Cai, had no visible injuries when he arrived at the First Affiliated Hospital of Guangzhou University of Chinese Medicine on August 8.

However, he had a strange and pained expression on his face and pointed at his rear to the staff.

Surgeons initially tried to extract the object from the man's anus but found that it was lodged in too deeply so they had to operate on him.

After two hours operation, where they opened Mr Cai up from his abdomen, they were able to remove the object.

It is thought the cylindrical object had already been inside the man for 27 hours before he sought medical help.

Media reports indicate the man had been involved in an altercation at a karaoke when the mystery object was inserted into his body.

Although the doctors did not disclose what exactly the object was, they revealed that it measured approximate 10 inches in length and 1.5 inches in diameter and was made of plastic.

The man is now recuperating in the hospital and has refused interviews by the media.

Dr Sun, who treated the man, said that he had previously treated a man in a similar disposition.

A chef had come into the hospital with a lodged cucumber, which had split his colon.
