The man, identified only by his surname as Liu, had been drinking with friends when he ingested the sharp bottle top.
The man attended A&E at around 10pm on Friday night at the Lianyungagn Hospital
He told medical staff on duty that he had swallowed the bottle cap because he had been drinking too fast.
Liu was given an X-ray, before doctors advised him to return to the hospital in the morning when his stomach was empty.
On Saturday morning, Liu was seen by the chief of gastroenterology, Dr Ju Weiping who decided to use a condom to wrap the bottle cap up before moving it out of the man's stomach.
The doctor, 60, said that by wrapping the cap in the latex contraceptive tool, it prevented it from scratching and damaging any organs as it was being extracted.
Dr Weiping originally trained as an electrical engineer before attending medical school in 1978.
He believes his training as an engineer gave him the skills he needed to safely extract the cap from Liu's stomach.
