Could someone please do me the favor of checking my attempted translation of an article, and helping me with the question-marked parts.

I greatly appreciate it.

"Horas antes, la ministra sudafricana de Defensa, Lindiwe Sisulu, aseguró que el premio Nobel de la Paz de 1993 fue ingresado para practicársele una laparoscopia, una técnica poco invasiva que permite observar la cavidad abdominal del paciente."


My attempt:
Hours earlier, the South African minister of defense, Lindiwe Sisulu, confirmed that the Nobel Peace prize of 1993 was deposited (used?) so he could receive (?) a laproscopy, a minimally invasive procedure which allows (doctors?) to view a patient's abdominal cavity.

Mil gracias.
