[Inter-observes agreement of Ishak and Metavir scores in histological evaluation of chronic viral hepatitis B and C]. / Reproductibilité des scores Ishak et Métavir dans la classification histopathologique des hépatites virales chroniques B et C.

Many classification systems are currently used for histological evaluation of the severity of chronic viral hepatitis, including the Ishak and Metavir scores, but there is not a consensus classification. The objective of this work was to study the intra and inter-observers agreement of these two scores in the histopathological analysis of liver biopsies in patients with chronic viral hepatitis B or C. Fifty nine patients were included in the study, 26 had chronic hepatitis C and 33 had chronic hepatitis B. To investigate the inter-observers agreement, the liver biopsies were analyzed separately by two pathologists without prior consensus reading. The two pathologists conducted then a consensual reading before reviewing all cases independently. Cohen's kappa coefficient was calculated and in case of asymmetry Spearman's rho coefficient. Before the consensus reading, the agreement was moderate for the analysis of histological activity with both scores (Metavir: kappa=0.41, Ishak: rho=0.58). For the analysis of fibrosis, the agreement was good with both scores (Metavir: kappa=0.61, Ishak: rho=0.86). The consensus reading has improved the reproducibility of the activity that has become good with both scores (Metavir: kappa=0.77, Ishak: rho=0.76). For fibrosis improvement was observed with the Ishak score which agreement became excellent (kappa=0.81). In conclusion, we recommend in routine practice, a combined score: Metavir for activity and Ishak for fibrosis and to make a double reading for each biopsy.

[Efficiency of endoscopic treatment with intra gastric balloon in severe to morbid obesity]. / Efficacité du traitement endoscopique par le ballon intragastrique au cours de l'obésité severe à morbide.

BACKGROUND: Obesity raises such a healthcare matter throughout the world. Its management is not only complex but also most often multidisciplinary. The medico-dietary treatment is of inconstant efficiency and the surgical treatment, though more efficient, presents a considerable morbidity-death rate. The endoscopic treatment through intra-gastric balloon avails a seducing alternative namely accounting for surgery preparation. AIM: To assess the efficiency of the endoscopic treatment through gastric balloon, both in the short and long term, and this is accounting for weight loss as well as tolerance. METHODS: We have carried out a retrospective study including the patients suffering from severe to morbid obesity and who had a gastric balloon implemented in our Endoscopy Unit between November 2005 and December 2007. RESULTS: Twenty one patients were included. The average age was 32,19 ± 12,65 years with extremes of 16 and 52 years. Fifteen patients suffered from morbid obesity. The patients' average weight was 134, 52 ± 26,46 kg (extremes 88 and 194 kg). Some co-morbidity was found out with 15 patients. Te balloon implementation (Héliosphère®) was carried out with no incidents in all patients. Six months after the balloon implementation, the average weight loss was 17,5% and the average loss of over weigh was 37%. In biological level, we noted a normalisation of fasting glycaemia in 28,6 % of cases, of the cholesterolemia in 100 %, of the triglyceridemia in 33,33%, of the uraemia in 42,8% and hepatic tests in 50 % of the cases. The metabolic syndrome disappeared in 28,57 % of cases. The assessment after a 5-year-period was marked by the need to surgical treatment in 4 patients and this is due to the loss of efficiency of endoscopic treatment. A bad tolerance of gastric balloon was observed in 34 % of the cases, dominated by sicknesses. Only one patient presented incoercible sicknesses with ionic troubles as well as deshydrating requiring the precocious extraction of the balloon after 48 hours of its implementation. CONCLUSION: The endoscopic treatment through intra gastric balloon is well tolerated but efficiently limited in time. It might be recommended in preparation for a surgical treatment or in case of contre- indication or surgery refusal.

Malignant epithelioid hemangioendothelioma: a case report.

Malignant epithelioid hemangioendothelioma (EH) is a rare tumor of vascular origin. We report a case of a woman who was found to have multiple hepatic masses in the right lobe of the liver on radiologic investigations, initially misdiagnosed as a metastatic carcinoma. The diagnosis of EH was made on histopathological study and confirmed by immunohistochemistry, which showed diffuse response for CD34 marker and no response to tissue CEA, HMB-45 or S-100 protein. Partial hepatectomy was made with good results.

[Epidemiology of hepatitis C in Tunisia]. / Epidemiologie de l'hepatite C en Tunisie.

BACKGROUND: Hepatitis C virus (HCV) infection is one of the main causes of chronic liver disease worldwide. AIM: To describe epidemiological patterns of hepatitis C in Tunisia. METHODS: Literature review. RESULTS: In Tunisia, the prevalence of HCV infection is about 0, 7 % in the general population with an increased transmission in the north of the country. Genotype 1b is the most frequent (76 % - 88 %).

[Factors predicting mortality in infected hospitalized cirrhotics patients: about 97 cases]. / Facteurs prédictifs de mortalité hospitalière chez les patients cirrhotiques infectes : À propos de 97 cas.

BACKGROUND: Infections are frequent in cirrhotic patients. They are potentially severe, modifying pejoratively the natural history of the cirrhosis and are suppliers of a heavy mortality. AIM: To determine the predictive factors of hospital mortality in cirrhotic infected patients. METHODS: We conducted a retrospective study including 97 cirrhotic patients hospitalized in the department of gastroenterology of Charles Nicolle's hospital, for a first infectious episode and not having received antibiotics in the previous 15 days. Clinico-biological, bacteriological, therapeutic and evolutionary data were collected. Scores were adopted and calculated such as the score of Child-Pugh, the score MELD (The Model for End-Stage Liver Disease) and the score SOFA (Sequential Organ Failure Assessment). These data allowed a descriptive study and an uni and multi-varied analysis. RESULTS: The median age of the studied population was of 59 ± 12 years with a sex ratio of 0.83. The diabetes was the comorbidity most frequently associated with the cirrhosis (26.8 % of the cases) Viral aetiology of the cirrhosis was dominant (3/4 of the cases) especially the virus C (62.5 % of the cases). The clinical presentation of the infection was polymorphic with presence of symptoms connected to the infection and the other connected to the progression of the liver disease. The fever was absent in 3/4 of the cases. The identified infections were, in order of frequency, urinary, infection of ascite, bronchopulmonary, cutaneous and gynecological. The responsible germs were especially bacilli gram negative of intestinal origin. The estimated scores of gravity were: a score of Child-Pugh C in 60 % of the cases, an average score MELD in 18±8 points and a score average SOFA in 8 ± 4 points. Multivariate study found that only encephalopathy, bilirubin level more than 40 µmol/l and creatinin level more than 120 µmol/l was independent factors predicting mortality. CONCLUSION: Infection in cirrhotic patients was a severe and mortal complication. The hepatic encephalopathy, the hyper bilirubinemia and the renal failure are predictive of the hospital mortality. The use of the scores of gravity: Child-Pugh, MELD and SOFA would an important help for the decision to admit in intensive care unit any infected cirrhotic patient.

[Epidemiological, clinical and therapeutic features of hepatocellular carcinoma in cirrhotic patients]. / Aspects épidémiologiques, cliniques et thérapeutiques du carcinome hépatocellulaire chez le cirrhotique.

BACKGROUND: Hepatocellular carcinoma (HCC) is the most frequent primitive hepatic tumor, the fifth most common cancer in the world,and the third highest cause of cancer-related mortality. The presence of cirrhosis is the main risk factor. AIM: To describe the epidemiological, clinical and therapeutic features of HCC. METHODS: Retrospective study including all the patients with HCC occurring in cirrhotic liver followed in the gastroenterological department of Charles Nicolle hospital between 1997 and 2009. RESULTS: A hundred and one patient were enrolled; 64 men and 37 women with a median age of 65.4 years (31-88 years). Cirrhosis was due to viral hepatitis B or C in 25.7% and 62.2% of cases respectively and was classified Child Pugh A, B and C in 30.7%,50.5% and 18.8% of patients respectively. HCC was inaugural in most cases (68.3 %) and it was revealed by a tumoral syndrome in 38.6% of cases, by decompensation in 22.7% and was discovered during systematic screening when cirrhosis was already known in 19.8% of cases. Diagnosis of HCC was non invasive, relying on imaging and alphafetoprotein in most cases (95%). 84 patients(83.2%) had an advanced HCC, with vascular or extra hepatic spread in 58 (57.5%) of them. Treatment was curative in 14 cases, based on surgical resection in one case and percutaneous ablation in 13 cases.Six patients received transarterial chemoembolization as a palliative treatment. In 71 patients, only symptomatic treatment was given. The median survival time was 11 months. CONCLUSION: In the majority of the cases, HCC was diagnosed at an advanced stage and treatment was only symptomatic.

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

BACKGROUND: 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. AIMS: To evaluate feasibility and tolerance of this investigation in elderly and to review the most frequent indications of colonoscopy in these patients. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

[Prevalence and risk factors of thromboembolic complications in inflammatory bowel disease]. / Prévalence et facteurs de risque des complications thromboemboliques au cours des maladies inflammatoires chroniques de l'intestin.

BACKGROUND: Patients with inflammatory bowel disease (IBD) are at increased risk of thromboembolic complications (TEC), which represent an important cause of morbidity and mortality. AIM: To assess the prevalence and risk factors of TEC in patients with IBD. METHODS: We conducted a retrospective study including all the IBD patients in the gastroenterological department of Charles Nicolle hospital between 2000 and 2010. Only thromboembolic events that had been diagnosed by an imaging procedure were counted. RESULTS: A total of 266 patients with IBD were consecutively included. TE events occurred in nine patients (3.4%); six men and three women. Their mean age was 31 years [15-64 years]. Five patients had Crohn's disease and four had ulcerative colitis. The types of TEC were deep venous thrombosis of the leg in five cases with pulmonary embolism in one of them, cerebral venous thrombosis in two cases, portal thrombosis in one case and jugular vein thrombosis in one case. Active disease was present in all cases at the time TEC occurred. CONCLUSIONS: In our study, the prevalence of TEC is 3.4% in patients with IBD. Deep venous thromboses of the leg are the most common TEC and all our cases occurs during the active phase of IBD.

Cerebral thrombosis in inflammatory bowel disease: a report of four cases.

The risk of thromboembolism is increased in inflammatory bowel disease and its symptoms may be overlooked. The commonest are deep vein thrombosis and pulmonary emboli. Cerebral thrombosis, in a particular stroke, is rare. Furthermore, its treatment can be complex. We present the cases of 4 patients with cerebral vascular involvement.

Variceal band ligation in the prevention of variceal bleeding: a multicenter trial.

BACKGROUND/AIM: Variceal bleeding is a life-threatening complication of portal hypertension with a high probability of recurrence. Treatment to prevent first bleeding or rebleeding is mandatory. The study has been aimed at investigating the effectiveness of endoscopic band ligation in preventing upper gastrointestinal bleeding in patients with portal hypertension and to establish the clinical outcome of patients. PATIENTS AND METHODS: We analyzed in a multicenter trial, the efficacy and side effects of endoscopic band ligation for the primary and secondary prophylaxis of esophageal variceal bleeding. We assigned 603 patients with portal hypertension who were hospitalized to receive treatment with endoscopic ligation. Sessions of ligation were repeated every two to three weeks until the varices were eradicated. The primary end point was recurrent bleeding. RESULTS: The median follow-up period was 32 months. A total of 126 patients had recurrent bleeding. All episodes were related to portal hypertension and 79 to recurrent variceal bleeding. There were major complications in 51 patients (30 had bleeding esophageal ulcers). Seventy-eight patients died, 26 deaths were related to variceal bleeding and 1 to bleeding esophageal ulcers. CONCLUSIONS: A great improvement in the prevention of variceal bleeding has emerged over the last years. However, further therapeutic options that combine higher efficacy, better tolerance and fewer side effects are needed.
