The multi-billionaire businessman is on the mend after the operation in a clinic in Lausanne, according to reports in Swedish daily Aftonbladet.
“I can confirm that Ingvar Kamprad is at a hospital in Lausanne, where he is now recovering after an operation”, Per Heggenes, Kamprad's spokesman and head of the Ikea Foundation in Holland, told the newspaper.
Heggenes added that it was a strictly routine operation and that the 85-year-old is not in any immediate danger.
“I have not talked to Ingvar Kamprad himself, but I have talked to other people who say that he is feeling well, he's in good spirits,” said Heggenes.
He could not say for sure when the businessman will be released from hospital, although he said it would probably be on Saturday.
On the latest Forbes Billionaires list, Kamprad dropped from No.11 to No.162, with his personal fortune apparently down from $17 billion to $6 billion.
Kamprad, who sold Ikea to the foundation years ago, gets his fortune from his investment firm, Ikano, which is run by his three sons.
The news of his operation comes during what has been a difficult year for Kamprad, with allegations over his past links to Nazi organisations once again making headlines.
