"Girl's uterus had ruptured that caused severe infection. A panel of surgeons, gynaecologists and anaesthetists decided to remove the uterus amid septicemia (infection)", Medical Superintendent of Guru Nanak Dev Hospital Tejbir Singh said.
The team of doctors also had to perform surgery on her intestines that had been damaged, he said.
The surgery was carried out last evening after the girl was brought here from Jalandhar following which she was shifted to the ICU unit, a hospital official said.
She would be observed closely for the next 72 hours since her condition remained critical even after the surgery, doctors attending on her said.
"The girl had suffered extensive blood loss and her haemoglobin count was mere 3 (against the normal range of 11.5-16). Sufficient blood units were infused to her but her condition would yet take time to respond medical treatment", Singh said.
The incident occurred on January 28 when three persons from the same village abducted and raped her while she was out of her home to relieve herself, they said.
The girl was abducted and raped brutally by three persons from the same village at her native village in Mandhala Channa village in Jalandhar on January 28 while she was out of her home to relieve herself, according to police.
The girl's father had told police that he filed a complaint ten days after the incident as his daughter told him about the alleged rape only now.
