    Abstract:
    The diagnosis of bleeding of gastrointestinal low tract is still a very controversial subject. At the Service of Digestive Endoscopy of Popoli (PE) Hospital, in a period of 4 years, 2074 colonoscopies have been effected. In 640 cases, that is 30.8%, the indication for the exam was suggested by rectal bleeding. In the 566 patients examined for minor rectal bleeding, the most frequent lesions were: haemorrhoids (35.3%), polyps (15.2%), malignant neoplastic disease (9.3%). In all active rectal haemorrhages (14 massive, 41 medium) an urgent colonoscopy has been carried out with a percentage of success of 90%; in the 20 cases of unexplained melena, colonoscopy has not led to a diagnosis; in the 14 patients with unexplained anemia, colonoscopy has shown 2 carcinomas, whereas in the 5 cases with occult blood in stools it has been diagnostic in the percentage of 60%. We have ascertained that, when barium enema was effected before colonoscopy, the diagnostic agreement between the two examinations was only of 21.4 (9/42); on the contrary there was an agreement of 95% when colonoscopy was effected before barium enema. In accordance with Siewert and Blum (25), Ottenjann (24) and Farrands (42), we believe that colonoscopy should be considered the main examination after either major or minor rectal bleeding, because it is a quick and safe investigation with high diagnostic specificity and sensitivity. We refuse William's position (41), because, even in presence of haemorrhoids or anal fissures, the colon must be studied as a whole, especially in a period when neoplastic disease of this tract of intestine is considerably increasing.(ABSTRACT TRUNCATED AT 250 WORDS)
