[Advantages of the use of medium-length colonoscope in the diagnosis of colonic diseases].

On the basis of their own experience, totaling 540 examinations, the authors explain the advantages offered by the medium-length (100 cm) optical fibroscope in the diagnosis of colonic diseases. They claim that the instrument under discussion is the most complete, being at once sturdy and easy to use and affording, despite its limite length, exploration of the ascending colon in 53.3% of the cases--a procedure for which the indications are on the other hand fairly limited.
