[Clinicobiological and morphological profiles of primary sclerosing cholangitis in Tunisia]

Primary sclerosing cholangitis [PSC] is a chronic cholestatic disease strongly associated, in the western series, to inflammatory bowel disease [IBD] and particularly to chronic ulcerative colitis. North African data are rare. To study the epidemiological, clinicobiological and morphological profile of PSC in Tunisia. A retrospective multicenter study extended over a period of 14 years [1995-2009], including all patients suffering from PSC, hospitalized in the four participants departments. We collected epidemiological, clinico-biological, histopathologic and morphological data for each patient. We brought together 33 patients [22 men and 11 women], middle aged 44 years. The disease was symptomatic in 73% of cases. Laboratory tests showed cholestasis [100%] associated with hyperbilirubinemia [72%] and a moderate cytolysis [78%]. Morphological analysis of bile ducts by cholangioMRI or endoscopic retrograde cholangio-pancreatography objectified diffuse damage of the biliary tract in 61% of cases. Association with IBD was found in 33% of cases [Crohn's Disease: 27%, chronic ulcerative colitis: 6%]. An association with autoimmune hepatitis was found in 6% of cases and primary biliary cirrhosis in 3% of cases. PSC is rare in Tunisia and affects men more often than women. The association with IBD is less frequent than in literature. It concerns essentially Crohn's disease. These data require confirmation by prospective multicenter studies

Colonoscopy in elderly: feasibility, tolerance and indications: about 901 cases

Colonoscopy is the standard investigation for colonic disease, but clinicians often are reluctant to refer elderly patients for colonoscopy because of a perception of higher risk and a high rate of incomplete examinations. To evaluate feasibility and tolerance of this investigation in elderly and to review the most frequent indications of colonoscopy in these patients. A pilot retrospective study including 901 patients from January 2005 to December 2009; divided into two groups. Group [I] included patients 75 years old and more, group [II] included patients 45 years old or less. All those patients underwent colonoscopy at the gastroenterology department of Charles Nicole hospital. The 1st group included 231 patients, and the 2nd group included 670 one. A past history of colorectal cancer was more frequent in the group I [33.3% versus 9.90%; p<0.05] however history of chronic inflammatory bowel disease was more frequent in group II [0 versus 40.6%; p<0.05]. The main indication of colonoscopy was constipation in group II [6.1% versus 27%; p<0.05] and chronic diarrhoea in group I [42.9% versus 16.4%; p<0.05]. Bowel preparation was poor in 30.4% cases of the group I and 12.9% of group II [p<0.05]. The tolerance was similar in the two groups. The incomplete colonoscopy rate was higher in the group I [38.3% versus 23.4%; p<0.05]. The most frequent cause of colonoscopy interruption was the poor preparation in group I and the bad tolerance in group II. Diverticular disease, polyps and colorectal cancers prevailed in group I, whereas inflammatory bowel disease was current in group II. In elderly patients, colonoscopy is safe, well tolerated and offers a good diagnostic yield. Its non completion was essentially due to the poor preparation. Sedation did not seem essential. The optimisation of results of colonoscopy requires an improvement of quality preparation
