how can you get a hole in your colon
Gastrointestinal perforation The cause can include trauma such as from a knife wound, eating a sharp object, or a medical procedure such as colonoscopy, bowel obstruction such as from a volvulus, colon cancer, or diverticulitis, stomach ulcers, ischemic bowel, and a number of infections including C. difficile.[2] A hole allows intestinal contents to enter the abdominal cavity.[2] The entry of bacteria results in a condition known as peritonitis or in the formation of an abscess.[2] A hole in the stomach can also lead to a chemical peritonitis due to gastric acid.[2] A CT scan is typically the preferred method of diagnosis; however, free air from a perforation can often be seen on plain X-ray.[2]
