    ABSTRACT: To identify the most common liver pathologies seen in our center, to find the prevalence of advanced fibrosis and cirrhosis in patients with chronic hepatitis B and C, and to correlate the histological and laboratory features of the most common diseases and compare between them. Liver biopsy procedures performed in our Gastroenterology Unit at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia were traced from records between the years 1997-2003. Clinical, histopathological, and laboratory features were recorded. We identified 574 liver biopsies during the study period. Of the 502 included patients, males were 58.6%. The mean age of the patients was 43.5 years. Approximately half of the biopsies (49%) were performed for patients with hepatitis C, followed by hepatitis B, for which 17% of the biopsies were performed. Patients with hepatitis B were approximately 10 years younger than patients with hepatitis C (p = 0.01). They were 10% more likely to be males. In terms of fibrosis, only approximately 17% of patients with hepatitis B and 27% of patients with hepatitis C had advanced fibrosis. Most liver biopsies performed in our center are performed for patients with hepatitis C. Rates of advanced fibrosis in our series are significantly lower than what was previously reported in other studies.

    ABSTRACT: To know the epidemiology and outcome of Crohn's disease at King Khalid University Hospital, Riyadh, Saudi Arabia and to compare the results from other world institutions. A retrospective analysis of patients seen for 20 years (between 1983 and 2002). Individual case records were reviewed with regard to history, clinical, findings from colonoscopy, biopsies, small bowel enema, computerized tomography scan, treatment and outcome. Seventy-seven patients with Crohn's disease were revisited, 13% presented the disease in the first 10 years and 87% over the last 10 years. Thirty-three patients (42.9%) were males and 44 (57.1%) were females. Age ranged from 11-70 years (mean of 25.3+/-11.3 years). Ninety-two (92%) were Saudi. The mean duration of symptoms was 26+/-34.7 mo. The mean annual incidence of the disease over the first 10 years was 0.32:100,000 and 1.66:100,000 over the last 10 years with a total mean annual incidence of 0.94:100,000 over the last 20 years. The chief clinical features included abdominal pain, diarrhea, weight loss, anorexia, rectal bleeding and palpable mass. Colonoscopic findings were abnormal in 58 patients (76%) showing mostly ulcerations and inflammation of the colon. Eighty nine percent of patients showed nonspecific inflammation with chronic inflammatory cells and half of these patients revealed the presence of granulomas and granulations on bowel biopsies. Similarly, 69 (89%) of small bowel enema results revealed ulcerations (49%), narrowing of the bowel lumen (42%), mucosal thickening (35%) and cobblestone appearance (35%). CT scan showed abnormality in 68 (88%) of patients with features of thickened loops (66%) and lymphadenopathy (37%). Seventy-eight percent of patients had small and large bowel disease, 16% had small bowel involvement and only 6% had colitis alone. Of the total 55 (71%) patients treated with steroids at some point in their disease history, a satisfactory response to therapy was seen in 28 patients (51%) while 27 (49%) showed recurrences of the condition with mild to moderate symptoms of abdominal pain and diarrhea most of which were due to poor compliance to medication. Seven patients (33%) remained with active Crohn's disease. Nine (12%) patients underwent surgery with resections of some parts of bowel, 2 (2.5%) had steroid side effects, 6 (8%) with perianal Crohn's disease and five (6.5%) with fistulae. The epidemiological characteristics of Crohn's disease among Saudi patients are comparable to those reported from other parts of the world. However the incidence of Crohn's disease in our hospital increased over the last 10 years. The anatomic distribution of the disease is different from other world institutions with less isolated colonic affection.

    ABSTRACT: To identify the cause, methods of diagnosis and management of malignant biliary strictures in our institution and compare with studies from other communities. From March 1998 through to August 2002, we reviewed 1000 files of patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) at the Gastroenterology unit, King Khalid University Hospital in Riyadh, Kingdom of Saudi Arabia for malignant biliary strictures (MBS). Clinical, laboratory data, method of diagnosis and management were recorded. Seventy-two patients (72/1000) with MBS were encountered. Forty one (57%) were males and 31 (43%) were females and the majority were Saudi nationals (82%). Jaundice and right upper quadrant pain were the most frequent symptoms in 84.7% and 52.8% of patients. Cholangiocarcinoma was present in 31 (43%) and pancreatic adenocarcinoma in 23 (31.9%) patients. Other malignancies found included gallbladder carcinoma in 5 patients (6.9%), ampullary carcinoma in 5 (6.9%), metastatic liver carcinoma in 4 patients (5.6%), hepatocellular carcinoma in 2 (2.8%) and lymphoma in 2 (2.8%). The diagnosis was entertained mainly by ERCP (93%). Endoscopic palliation was carried out in 77.8% of patients, percutaneous transhepatic drainage in 13.9% and surgery in 6 (8.3%). The mean survival was higher for the endoscopic compared to the percutaneous transhepatic and surgery groups (6.9 +/- 4.13, 4.27 +/- 4.29 and 3.67 +/- 2.65 months). In non-resectable tumors, ERCP is the optimal method of diagnosis and palliation of MBS.
