Colonoscopy result: a cockroach

As mentioned in Deadly Kingdom, cockroaches have been found in pretty much all human orifices. Here's a lovely example:

NCBI ROFL: An unusual finding during screening colonoscopy: a cockroach! | Discoblog | Discover Magazine
"A 52-year-old woman with a history of depression was referred by her primary physician for colorectal cancer screening. She had no family history of colorectal cancer and a review of systems was positive for abdominal bloating. Bowel preparation was done using 4 L of polyethylene glycol the evening prior to screening colonoscopy. The procedure was uncomplicated with no gross mucosal pathology, however, an insect was found in the transverse colon."

The roaches above are harmless pets, never found in the location mentioned in the article. I hope. (Thanks to the crew at Twin Cities Reptiles for this photo op.)


  1. Colon cancer is cancer of the large intestine (colon), the lower part of your digestive system. Rectal cancer is cancer of the last 8 to 10 inches of the colon. Together, they are often referred to as colorectal cancers , and they make up the second-leading cause of cancer-related deaths in the United States. Only lung cancer claims more lives.
