Former South African president Nelson Mandela was released from hospital Sunday, a day after being admitted for a long-standing abdominal complaint.
Officals said he underwent a minor diagnostic surgery to determine the cause. There were unconfirmed media reports he may have a hernia.
South African President Jacob Zuma released a statement saying that Mandela was "surrounded by his family and is relaxed and comfortable."
A spokesman for Zuma, Mac Maharaj, said the 93-year-old Nobel peace laureate had undergone a laparoscopy, a procedure that involves surgeons making an incision in the belly to insert a thin, lighted tube to look at abdominal organs.
A government statement said tests "did not indicate anything seriously wrong" with the anti-apartheid icon and that he had been sent home.
Officials did not disclosed where he was being treated to protect his privacy.
