[Inflammatory intestinal diseases and their extra-intestinal manifestations observed at Liban].

101 cases classified as inflammatory bowel disease at the Hôtel-Dieu de France Hospital between 1982 and 1994 were investigated. Files containing a sure diagnosis and complete clinical and biological investigations were included. 65 files were retained for the study: 48 cases had ulcerative colitis (UC), 17 had Crohn's disease (CD). UC averaged 4.7 admissions per 10,000 admissions to the hospital, while CD averaged 1.54 per 10,000. The UC/CD ratio was 2.8 and the Female/Male ratio was 1.4 for UC and 0.9 for CD. Medium follow-up was 6.4 years. 30% of our group was followed for more than 10 years. Overall frequency of extra-intestinal manifestations was similar to that reported worldwide. This is especially true for UC. However, no cases of ankylosing spondylitis, sclerosing cholangitis or erythema nodosum were found. One case of pyoderma gangrenosum was found in the series of CD. Extra-intestinal manifestations were found in 54% of UC patients and 94% of CD patients, probably because milder cases of this disease were misclassified as infectious diarrhea.
