A cooperative study on the detection of @entity14 and XXXX in France.

@entity1 @entity1127 @entity5 @entity189 @entity4056 @entity6523 @entity14
Systematic investigations testing for the presence of @entity1127 and @entity5 of the large bowel were conducted in a population of 1,369 inpatients and outpatients, aged 45-70 years, in eight university departments of gastroenterology or abdominal surgery (Toulouse, Dijon, Paris, Marseille, and Strasbourg). Double-contrast barium enema and proctosigmoidoscopy examinations were carried out in all cases, whereas total coloscopy was performed only in the case of detected @entity5 . A questionnaire including 233 parameters (age, sex, family, and personal history and symptoms) was completed for each @entity1 . A total of 414 lesions were detected in 252 @entity1 , including 245 @entity6523 , 8 transformed @entity1127 , and 30 @entity189 ; 3 of 4 lesions were located in the rectum or sigmoid. @entity5 or @entity6523 were found in 13% of the @entity1 . The prevalence of these lesions in the population studied was increased in @entity1 with rectorrhagia (19%) or with a personal history of surgery for @entity14 or @entity1127 (23%). In the @entity1 without rectorrhagia or a history of @entity4056 , the incidence was 9.7%. It was significantly increased in males and @entity1 more than 50 year old. The efficacy of proctosigmoidoscopy and double-contrast barium enema was compared in 909 @entity1 . Sensitivity and specificity were, respectively, 35% and 99% for endoscopy, 96% and 94% for radiology.
