NASHVILLE, Tenn. -- A Pulaski man is concerned about the lack of information the York Veterans Medical Center is giving about an investigation into problems with colonoscopy equipment used during surgeries.

He's especially worried because he recently had a procedure done at the center.

After avoiding it for years, Joe Wiggins finally had a colonoscopy done 18 months ago at the York Veterans Administration Hospital in Murfreesboro.

"I've never had any ill effects from it," said Wiggins.

He said he had no problems or complications and was pleased overall with the care he received.

Wiggins said he was bothered to learn that a month ago, York discovered "a potential infection threat" to Veterans from "specific colonoscopy equipment used."

He said he would have liked to hear the news from VA. Wiggins hasn't received a phone call or a letter from York Medical Center, and, apparently, neither has anyone else.

In an e-mail from the VA's spokesman, the hospital said, "Any affected veterans will be notified and screened should the result of the clinical review identify a risk."

The spokesman is not giving any specifics as to a timeframe when these problems may have occurred or how many patients might be affected.

The hospital said it has known about a potential problem since Dec. 1. A clinical review is in process, and it's unknown how long it will take to complete.

For now, Wiggins, who spent 22 years serving in the U.S. Navy, said he feels he isn't being properly served with information.

"I would like to be told that I'm OK," he said. "It's a situation where, even if I don't fall into the group that's involved with the contamination, I'd like to be given a notice that I'm not in that group."
