Colonoscopy is a test that enables the inspection of the entire colon using a fiberoptic tube known as colonoscope. A colonoscopy is used to detect abnormalities in the colon such as colon cancer and inflammation. Colon perforation occurs when the colonoscope punctures the wall of the colon during a colonoscopy 2. Emedtv.com states that risk of colon perforation is increased in patients with existing colon abnormalities 2. Patients should be aware of symptoms of colon perforation
If you are experiencing serious medical symptoms, seek emergency treatment immediately.
The National Institutes of Health states that bleeding from colon perforation may occur immediately after a colonoscopy or even several days later 123. Patients may notice bright red blood in the stool or notice blood trickling down the anus as they defecate. Patients may also experience severe weakness and dizziness upon standing. Patients should contact the doctor immediately when they notice signs of bleeding in the colon. They may require surgery to fix the colon perforation. Patients who have lost massive amounts of blood may require blood transfusions.

What Causes Blood Clots in Stools?
Perforation of the colon results in a hole in the bowel that allows bowel contents to enter the bloodstream and circulate to the rest of the body, resulting in a blood infection known as sepsis. Patients with sepsis due to colon perforation may experience fever, chills, shaking, confusion, rapid pulse and delirium. Sepsis is a serious illness that requires hospitalization in the intensive care unit.
According to the National Institutes of Health, a perforated colon may result in a condition known as secondary peritonitis 13. Secondary peritonitis is the inflammation of the peritoneum, which are tissues that cover the colon and other abdominal organs 3. Peritonitis occurs when bacteria enter the peritoneum through the hole in colon. Signs and symptoms of peritonitis include fever, shaking chills, abdominal tenderness and a firm board-like abdomen.
Abdominal Pain and Distension
Diverticulitis & Colonoscopy
According to the National Institutes of Health, patients with colon perforation may experience severe abdominal pain at the site of colon puncture 13. The abdominal pain may be aggravated by bending or lifting heavy objects. Abdominal distension may be caused by the pooling of blood in the colon and the surrounding regions due to colon perforation.
