I had a colonoscopy yesterday, and it was a great learning experience. I am fortunate that the anesthetic they gave me had little effect, and the doctor was open to answering questions from an inquisitive patient.
Here are the notes I took on the procedure. What is the basic colon inspection procedure The doctor told me that they put the probe in all the way to the appendix without really doing any observations. The colon sort of hugs the probe and you cannot see much. Once the probe gets to the appendix, they inflate the colon with CO2 and do their inspection on the way out. Here is a good image of the colon.
You can see the appendix at the end. Why is carbon dioxide used to inflate the colon? While in my upper colon, the doctor told the nurse he wanted to use CO2 to inflate that section. I asked the doctor why CO2 instead of air.
He said that CO2 is absorbed by the colon into the bloodstream very quickly and you just breath it out. Air is not so quickly absorbed and, if used, would leave you feeling bloated after the procedure. Has the doctor ever seen an infected appendix? He said that an infected appendix is no issue as long as it can drain into the colon. An infected appendix will eventually heal as long as it can drain. You get into trouble when an infected appendix cannot drain and it ruptures.
I was floored at how much the technology has improved since my last colonoscopy. My last colonoscopy was 9 years ago. The screen images back then were low resolution and black and white. These were high-res and in color. The level of detail was amazing.
