Place de la ligature elastique dans la prevention secondaire de l'hemorragie digestive par rupture de varices oesophagiennes. Etude prospective de 102 cas

The aim of this study was to assess the efficacy and morbidity of endoscopic variceal ligation for the prophylaxis of rebleeding from oesophageal varices. This work is a prospective study including 102 patients having had at] least one episode of variceal bleeding. The mean age is 52,5 years. Oesophageal varices were eradicated in 83,3% of cases after an average of 3,5 sessions. Recurrence of oesophageal varices after eradication was observed in 22% after an average follow-up of 7 months. 10 patients died before eradication of oesophageal varices from causes unrelated to the technique. The endoscopic variceal ligation is effective for eradication of oesophageal varices, with a low morbidity. This technique appears to be a method of choice in the prophylaxis of rebleeding from oesophageal varices

densite minerale osseuse au cours de la maladie de Crohn: Apport de l'osteodensitometrie chez 53 patients

Fifty-three patients with Crohn disease were included in A prospective study. Bone mineral density was measured at the Femoral neck and lumbar spine by dual-energy X-ray absorptiometry. Ten variables were analyzed in search of an association with bone demineralization; Age, sek, nutritional state, smoking, duration of the disease, hormonal status, inflammatory syndrome, site of disease ileal, colic or ileocolic, accumulated doses of corticoids and intestinal resection. A bone demineralization was observed in 58,5% of cases. The ileum location and the corticotherapie were predictives of bone demineralization. Crohn disease is a disease at high risk of bone demineralization. Predictors of the bone loss were smoking, long duration of the disease, ileal site and systematic corticotherapy
