Colonoscopy is now a routine examination in the diagnosis and the follow-up of I.B.D. The most typical aspects of endoscopic and histological lesions are described. Colonoscopy and histological study of endoscopic biopsies permit a differential diagnosis of Crohn's disease and ulcerative colitis in 90% of the cases. Certain cases remain indeterminate even after colectomy.
This study investigated the suitability of propofol as a sole agent for continuous sedation in 100 unpremedicated patients during gastrointestinal endoscopy. The propofol was given very slowly (average 62.7 seconds) in order to prevent apnoea during induction, and the dose adjusted according to age (68% of patients were older than 50 years) and ASA grade (32% were ASA grade 3 or 4). There was no correlation under these circumstances between the observed haemodynamic variations and the age or ASA grade of the patients. The infusion rate during maintenance was also adjusted for age, and for the type of endoscopy. The mean rate was 4.3 mg/kg/hour. Recovery was rapid and of excellent quality; 77 patients were awake within 10 minutes and 99 reported total amnesia.

This article reports the results of our first 100 examinations of the upper gastrointestinal tract and the colon in children and infants, using standard fiberscopes and also pediatric models. The procedure could be performed under sedation in 80% of the cases and general anesthesia was required mainly with standard fiberscopes. Compared to roentgenographic findings, fiberendoscopy proved to be more reliable in superficial mucosal lesions and gastrointestinal bleeding. Colonoscopy though difficult, is valuable in diagnosing rectal bleeding lesions and as a follow-up technique in inflammatory bowel diseases.
Oesophageal dilatations were performed 55 times in 10 children aged 2 months to 8 years presenting with acquired strictures of several origins. Classical bougienage with rubber material and newer technique with the Eder-Puestow's metallic olives system were used successively. The conjunction of the latter with systematic use of fiberendoscopy enhances considerably the safety of the procedure and permits better functional results.
