The unidentified patient, due to confidentiality, was hospitalised after he complained of abdominal pain. He got admitted to a hospital in the Baltic port city of Klaipeda.
An X-ray showed that he had pieces of metal inside his stomach. Some of them even measured as big as 10cm (4in).
"During the three-hour operation with X-ray control, all foreign bodies, even the smallest ones, in the patient's stomach were removed," surgeon Sarunas Dailidenas said.
The hospital even provided the local media with a photograph of a surgical tray that shows a pile of nails and screws.
"We've never seen anything like it," Algirdas Slepavicius, head surgeon at Klaipeda Hospital told local media.
The patient was in stable condition after the operation, he added. Although the doctors added that the foreign bodies had damaged the front wall of the stomach.
