No a colonoscopy does enter a small portion of the small intestine...he said my colon looks good but irritation is in the small intestine....he took a sample of the small intestine for a biopsy....what would the biopsy be looking for?...bacteria?...cancer?
I don't think that a colonoscopy can reach the small intestine - I thought only the large intestine. The small intestine needs to be examined through an ESSB (Esophagus, Stomach, and Small Bowel) test (you drink a barium milkshake and they watch it pass through your system while taking x-rays). The doctor must be talking about your large intestine . I would clarify with the doctor. Not sure if the biopsy would detect yeast overgrowth - :( sorry,.
