RESUMO
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.

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, sex, 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 corticothérapie 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.
