South African officials say Nelson Mandela has been discharged from hospital.
President Jacob Zuma's office said the former South African president was sent home after checks "did not indicate anything seriously wrong."
Officials earlier said the 93-year-old Nobel Prize laureate had undergone a laparoscopy -- a procedure which involves inserting a tiny camera through the abdomen or pelvis to carry out an internal investigation.
Sisulu said Mandela had been suffering from "ongoing discomfort" on a regular basis.
The Nobel Prize laureate spent 27 years in prison for fighting the white-minority rule of the apartheid era.
He became South Africa's first black president in 1994, serving one five-year term.
He retired from public life in 2004, but remains a hugely popular figure.
Mandela, who is known to be in frail health, spent several days in hospital just over a year ago with respiratory problems.
Since then he has not appeared in public.
