    ABSTRACT: Background: Upper gastrointestinal endoscopy (UGE) is an increasing and reliable procedure. Given the high costs and potential risks, appropriate indication of UGE may be facilitated by referring to qualifying criteria such as those devised by the European Panel (EPAGE). This prospective study evaluates the applicability and efficacy of these criteria in clinical practice. Methods: Cross sectional study. Consecutive patients were referred to our unit endoscopy for diagnostic upper gastrointestinal endoscopy between January 2011 and June 2011. Demographic data, indication of the procedure, and endoscopic diagnosis were collected. The appropriateness of UGE was assessed based on EPAGE II criteria before the procedure. Results: EPAGE criteria were applicable in 89.1% of cases. They were 78 men (48.1%) and mean age was 49 years [14 - 91]. Indications for UGE were extremely appropriate, appropriate, inappropriate and uncertain in 21.6%, 47.4%%, 8.8% and 22.2% respectively. Among patients with clinically significant lesions detected by UGE, 70.7% had an appropriate indication. Clinically significant lesions were disclosed in 59% of the appropriate group and 54% of the inappropriate group. All cancers were observed in patients with appropriate indications. Patients with appropriate indication were older than patients belonging to the inappropriate group (53.6 years versus 39.9 years, p =0,0001). Conclusion: In this present study, EPAGE criteria were applicable in 89.1% and indication was judged appropriate in more than two-third of cases. However, clinical significant lesions were observed in a proportion of patients with inappropriate indication, and in some relevant clinical situations EPAGE criteria were not applicable. Therefore, even if these criteria are helpful for decision-making, final decision must however rely upon practitioner. Qualifying criteria for an appropriate selection of endoscopical procedure adapted to our population are advisable.

    ABSTRACT: De novo autoimmune hepatitis (AIH) is a rare disorder first described in 1998. It occurs in patients who underwent liver transplantation for a different etiology. We present the case of a 56-year-old woman who was diagnosed with primary biliary cirrhosis and had liver transplantation for refractory pruritis. Seven years after transplantation, she presented alterations in the hepatic profile with hypertransaminasemia, elevated alkaline phosphatase and gamma-glutamyl-transferase. Her liver functions test also showed elevated IgG levels. Serum autoantibodies were negative except for antimitochondrial antibodies. Histological findings indicated features of AIH without bile duct damage or loss. She had a pretreatment AIH score of 13 points and a post treatment score of 15 points according to the International AIH Group. The patient was treated effectively with prednisolone and her liver function and globulin levels rapidly returned to normal.

    ABSTRACT: Introduction: Bacterial infection (BI) is a complication that occurs frequently in patients with cirrhosis and represents a major cause of mortality. Identification of factors associated with an increased risk of infection is a crucial step in their management as they recognize at risk patients. In this subset of patient, prophylactic antibiotics improve the prognosis. The aim of this present study is to determine factors associated with BI in cirrhosis. Materials and methods: Retrospective study including 134 consecutive cirrhotic patients was conducted in the department of Hepato-gastro-enterology of the Mongi Slim Hospital over a period of 29 months. Clinical, biological, bacteriological, therapeutic data and outcome were collected. These data allowed a descriptive study as well as univariate and multivariate analysis. Results: We documented 69 cases of BI meaning a prevalence of 51.5%. Infection sites were dominated by ascitic fluid and urine followed of lungs skin and soft. Identified predictors of BI, by univariate analysis, were: a paracentesis and rupture of oesophageal-gastric varices in the week before hospitalization, severity of cirrhosis evaluated by the Child C and MELD score > 17, refractory ascites and the absence of rifaximin intake in the previous 30 days. In multivariate analysis, only the absence of rifaximin intake in the previous 30 days (p=0.005, OR 5.4) before BI was independently related to the occurrence of BI. Conclusion: BI is one of the most frequent complications of cirrhosis. Factors associated with BI identified in our series may allow recognizing patients at risk. In this subgroup, a proper care could improve the prognosis. Our results suggested that rifaximin could have an elective place in the prevention of BI without selecting resistances. These results should however be confirmed.

    ABSTRACT: Introduction Le foie étant le site principal du métabolisme des antalgiques, en cas de cirrhose, leur biotransformation est modifiée, exposant au risques d’effets indésirables parfois sévères. La prise en charge de la douleur chez le cirrhotique est une situation fréquente et il n’existe pas de recommandations précises sur le sujet. Le but de cette mise au point est de préciser les connaissances actuelles relatives à la prescription d’antalgiques chez le cirrhotique afin de proposer une conduite pratique. Méthodes Recherche bibliographique en se référant aux bases de données bibliographiques MEDLINE en utilisant les mots clés suivants: antalgiques ou analgésiques, cirrhose ou insuffisance hépatique, paracétamol, anti-inflammatoires non stéroïdiens (AINS), opioïdes. Résultats Plusieurs mécanismes altèrent la clearance hépatique en cas de cirrhose: modification des flux vasculaires, shunt porto-systémique, insuffisance hépatocellulaire et hypoalbuminémie. Le paracétamol à une dose ne dépassant pas 2-3g/24h est bien toléré et recommandé en 1re intention. Les AINS sont contre-indiqués. Le tramadol est possible à condition d’espacer les prises et de réduire les doses. Le fentanyl, l’hydromorphone, la morphine sont les opioïdes forts dont la pharmococinétique est la moins altérée; ils peuvent être prescrits en veillant à diminuer les doses pour les premiers et espacer les prises pour la morphine. Parmi les co-analgésiques, les tricycliques à doses réduite, la gabapentine et la prégabaline sont le plus souvent bien tolérés. Conclusion La prise en charge de la douleur chez le cirrhotique est une situation de plus en plus fréquente qu’il est possible de contrôler à condition de choisir l’antalgique le mieux adapté, en respectant les doses et les paliers et en surveillant la survenue d’effets indésirables.

    ABSTRACT: Solitary rectal ulcer syndrome is an uncommon and benign defecation disorder. Occidental series are scarce and to our knowledge, Tunisian data are not available. The aim of this study was to evaluate the clinical, endoscopic and histological spectrum of the solitary rectal ulcer syndrome. All the patients diagnosed with solitary rectal ulcer syndrome from January 2001 to 2012 were included in the study. The medical records were reviewed retrospectively to evaluate the clinical spectrum of the patients along with the endoscopic, histological and therapeutic findings. A total of 15 patients were evaluated: 7 males; mean age 42.6 years. Bleeding per rectum was present in 66% and dyschezia in 73%. Endoscopically, solitary lesion was present in 66% patients. The most frequent dynamic abnormalities shown by defecography were of rectal intussusception (53%). Anorectal manometry was performed in seven cases disclosing dyssynergia in 2 cases. Thirty patients underwent surgery, always after failure of medical treatment and one patient was treated with biofeedback. Rectopexy was the most utilized technic. After a mean follow-up of 29 months, total regression of symptoms was noted in 50% of patients who underwent surgery. In this cohort, diagnostic and therapeutic spectrum of solitary rectal ulcer syndrome was comparable to occidental features. Nevertheless, accesses to manometry and defecography as well as biofeedback were limited.

    ABSTRACT: Nodular lymphoid hyperplasia (NLH) of the gastrointestinal tract is a rare disease usually reported in patients with congenital or acquired immunodeficiency and chronic gastrointestinal infections. However, no case of NLH in a patient receiving immunosuppressive therapy has been reported to date. We describe the case of a woman who developed chronic diarrhea related to NLH 9 years after liver transplantation. Other causes of diarrhea and NLH were excluded. Her immunosuppressive regimen consisted on mycophenolate mofetil (MMF) and tacrolimus. Reduction of MMF dose improved symptoms but led to a rising aminotransferase level. Given the risk of graft rejection, MMF at full dose was resumed and she was started on symptomatic treatment for diarrhea. The role of immunosuppressive drugs in the pathogenesis of NLH may be related to the reduction of T- and B-lymphocyte proliferation and decreasing antibody production. NLH will further develop to compensate functionally inadequate lymphoid tissue, as reported in congenital immunodeficiency states. Copyright © 2015 Elsevier Inc. All rights reserved.

    ABSTRACT: Behçet's disease (BD) is a multisystemic disorder that involves vessels of all sizes. Superior vena cava (SVC) thrombosis is a rare complication that can lead to the development of various collateral pathways. A 31-year-old man presented with SVC syndrome. He had a history of recurrent genital aphthosis. Computed tomography revealed extensive thrombosis of the right internal jugular, axillary, and subclavian veins with collateral circulation. The patient was diagnosed with BD, and he was started on anticoagulation and immunosuppressive therapy. One week later, he presented with haematemesis. Upper gastrointestinal endoscopy disclosed varices in the upper third of the oesophagus with stigmata of recent bleeding. Portal hypertension was ruled out. Anticoagulation therapy was discontinued. He was discharged on immunosuppressive therapy. Bleeding from downhill oesophageal varices should be suspected in any patient presenting with upper gastrointestinal bleeding and a history of SVC syndrome due to BD.

    ABSTRACT: Background and aims Minimal hepatic encephalopathy (MHE) is the mildest form of the spectrum of hepatic encephalopathy that impairs health-related quality of life. The aim of this study is to evaluate the prevalence of MHE in patients with liver cirrhosis and analyze risk factors. Methods Between September 2011 and December 2012, consecutive cirrhotic patients seen in our department were evaluated. Patients included were screened by the psychometric hepatic encephalopathy score (PHES) battery comprising 5 tests: number connection test A and B, line tracing test, serial dotting test and digit symbol test. Patients included were regularly followed-up for the development of overt hepatic encephalopathy, driving accidents, falls and death. Results We included 45 cirrhotic patients. Etiology of cirrhosis was viral in half of cases. Child-Pugh score was A in 55.6 %, B in 26.7 % and C in 17.8 %. Median Meld score was 14. According to the PHES score, MHE was detected in 44.4 % of patients. Univariate analysis identified 4 variables significantly associated with the presence of MHE: age ≥ 55 years (P = 0.031), poor educational status with years of study < 9 years (P = 0.007), MELD score ≥ 15 (P = 0.002) and Child-Pugh ≥ 7 (P = 0.001). At multivariate analysis, the only independent risk factor of MHE was a MELD score ≥ 15 (OR = 15.4; P < 0.001). During the follow-up, patients with MHE developed more often overt encephalopathy, falls and driving accidents, and had a lower survival, although the difference was not statically significant. Conclusion In this preliminary small series, prevalence of MHE in Tunisian cirrhotic patient was 44.4 %. A MELD score ≥ 15 was the only independent risk factor. MHE had a negative impact on the outcome, justifying an early diagnostic. Adequate therapy may improve cognitive function.

    ABSTRACT: Background: Ischemic colitis is the most common form of intestinal ischemia. The presence of diarrhea and mild lower gastrointestinal bleeding should guide the diagnosis. Although many laboratory tests and radiographic images may suggest the diagnosis, colonic endoscopic with histological analysis of biopsies is the gold standard for identification of colonic ischemia. aim : The aim of this study was to resume in 5 points: the epidemiology, the clinical features, the diagnostic approach and the management of ischemic colitis in five points. methods: Review of literature. results: Incidence of ischemic colitis was between 3 and 10%. The clinical presentation is predominated by the non gangrenous form associating abdominal pain, tenderness, diarrhea and lower gastrointestinal bleeding. The most frequent causes are represented by systemic hypoperfusion. Laboratory tests can orientate the diagnosis but are unspecific. Radiographic images based on computed tomography or more recently magnetic resonance imaging may suggest the diagnosis, but the confirmation will be given by endoscopic visualization of colonic mucosa with histological analysis of biopsies. Conservative treatment is the most often sufficient to improve colonic lesions. Surgical treatment is reserved for perforations and strictures. Conclusion: The incidence of colonic ischemia is difficult to ascertain. The diagnosis is usually made by medical history, examination, and endoscopy which have become the diagnostic procedure of choice. A high index of suspicion and prompt management are essential for optimum outcomes in patients with colonic ischemia.

    ABSTRACT: Background Loss of bone mass is frequently identified in cirrhosis, leading to fragility fractures and significant morbidity. The pathogenesis is not completely elucidated. Objectives The aim of this study is to assess the prevalence of bone loss in cirrhotic patients and identify risk factors. Methods Bone mineral density (BMD) was performed in patients with cirrhosis seen in our department in 2011, by X-ray absorptiometry (DEXA) at both lumbar spine and femoral neck sites. Other diseases disturbing the bone density were excluded. Osteopenia was considered if T score < -1.5 DS and osteoporosis if T-score <-2.5 DS. We collected clinical data including risk factors for bone mass loss and nutritional status. Results Fifty patients with cirrhosis were included. They were 28 males and 22 females with a mean age of 54 years (17-84). Aetiology of cirrhosis was viral in 48% and auto-immune in 20%. Child-Pugh score was C in 32% and mean Meld score was 14 (5-32). BMD disclosed osteopenia in 32% and osteoporosis in 32%. Mean bone mass and T score were 0.94 kg/m2 and -0.67 DS in femoral neck; 0.98 kg/m2 and -1.2 DS in lumbar spine. History of fracture was present in 10% of cases. Low bone mass was correlated with female sex (p=0.01), age (p=0.04), sedentary (p=0.01) and Child Pugh C (p=0.03) but not with nutritional status. Conclusions In our study, prevalence of osteoporosis was 32%, as reported in Occident. Advanced liver disease in association with classical risk factors of osteoporosis was correlated with BMD. This high prevalence suggests that bone status should be evaluated routinely in patients with cirrhosis. Disclosure of Interest None Declared

    ABSTRACT: Toxic megacolon is a rare and serious complication of Crohn’s disease. Because of the associated high morbidity and mortality, early recognition and management of toxic megacolon is important. Through two cases of toxic megacolon complicating Crohn’s disease, we assessed the clinical, radiologic and therapeutic characteristics of this complication. A 35-year-old man presented a first course of Crohn’s disease treated with corticosteroid. He exhibited sudden severe abdominal pain and distension with shock. A plain abdominal radiography revealed toxic megacolon. He underwent medical therapy, but symptoms not relieved. The patient underwent subtotal colectomy with ileostomy. The resected specimen confirmed the diagnosis. Recovery of digestive continuity was performed. Endoscopic evaluation six months later did not shown recurrence. A 57-year-old man presented with severe acute colitis inaugurating Crohn’s disease, was treated with corticosteroid and antibiotics. He exhibited signs of general peritonitis. Computed tomographic examination revealed toxic megacolon with free perforation, showing prominent dilation of the transverse colon and linear pneumatosis. The patient underwent emergent subtotal colectomy and ileostomy. The final histological patterns were consisting with diagnosis of Crohn’s disease associated with cytomegalovirus infection. The patient underwent antiviral therapy during 15 days. Because of the high risk of postoperative recurrence, he underwent immunosuppressive therapy. Recovery of digestive continuity was performed successfully. Toxic megacolon in Crohn’s disease is a serious turning of this disease. We underscore the importance of early diagnosis of toxic megacolon and rapid surgical intervention if improvement is not observed on medical therapy.

    ABSTRACT: Background: The Budd-Chiari syndrome is a rare disease, often fatal if not treated optimally. It is characterized by a blocked hepatic venous outflow tract. aim: This review attempted to present pathophysiology, aetiologies,diagnosis and therapeutic modalities of the Budd-Chiari syndrome. Methods: Review of literature. Results: Budd-Chiari syndrome is a complex disease with a wide spectrum of aetiologies and presentations. Hematologic abnormalities, particularly myeloproliferative disorders, are the most common causes of the Budd-Chiari syndrome. The clinical presentation is governed by the extent and rapidity of the hepatic vein occlusion. Doppler-ultrasound, computed tomography or magnetic resonance imaging of hepatic veins and inferior vena cava are usually successful in demonstrating non-invasively the obstacle or its consequences. A therapeutic strategy has been proposed where anticoagulation, correction of risk factors, diuretics and prophylaxis for portal hypertension are used first; then angioplasty for shortlength venous stenosis; then Transjugular Intrahepatic Portosystemic Shunt (TIPS); and ultimately liver transplantation. Treatment progression is dictated by the response to previous therapy. This strategy has achieved 5-year survival rates approaching 70%. Medium-term prognosis depends on the severity of liver disease. Conclusion: The diagnosis of the Budd-Chiari syndrome must be considered in any patients with acute or chronic liver disease. Management of this syndrome should follow a step by step strategy.
