The natural history of isolated rectosigmoid adenomatous polyps: is flexible sigmoidoscopy a safe alternative for surveillance?
The majority (65 percent) of patients with isolated rectosigmoid polyps have additional polyps on long-term surveillance, and 60 percent of patients will have these polyps located proximal to the reach of a sigmoidoscope. Therefore, flexible sigmoidoscopy is not a safe alternative for surveillance of patients with isolated rectosigmoid polyps.
Immunomodulator use is associated with a decreased risk of first surgery among patients with non-stricturing non-penetrating CD. Early immunomodulator therapy may be beneficial in preventing first surgery in this population that has yet to develop penetrating or fistulizing complications.
