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.)
