SYDNEY, Australia (AP) -- A Sydney woman demanded an explanation Tuesday from a hospital where a pair of scissors were left in her abdomen after surgery and said she planned to sue.

Pat Skinner, 69, had part of her colon removed at Sydney's St. George Hospital in May 2001. But she said that she continued to suffer intense pain in her abdomen for months after the operation.

Eventually, she demanded doctors x-ray her abdomen. They did and discovered the 6.7-inch pair of scissors, which were removed in October 2002.

"It was like a nightmare seeing those scissors up on the screen," Skinner told Sky News television Tuesday. "It was very, very traumatic and extremely painful."

The hospital has apologized to Skinner for the accident, but Tuesday she said plans to take legal action, although she did not provide any details
