Colonoscopy after colon cancer resection. "We recommend that, after the 1-year colonoscopy, the interval to the next colonoscopy should be 3 years (i.e., 4 years after surgery or perioperative colonoscopy) and then 5 years (i.e., 9 years after surgery or perioperative colonoscopy). Subsequent colonoscopies should occur at 5-year intervals"

Symptoms of small intestinal bacterial overgrowth include abdominal distension, flatulence, bloating, diarrhea, and abdominal pain. The definitive diagnosis of SIBO involves the presence of 10^5 colony forming units per milliliter of coliform bacteria isolated from the proximal jejunum. This is difficult to sample with endoscopy so breath testing is an alternative method of diagnosis. Weight loss and nutritional deficiency are possible.
