[Efficiency of endoscopic treatment with intra gastric balloon in severe to morbid obesity]

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. 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. 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. 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[registered sign]] was carried out with no incidents in all patients. Six months after the balloon implementation, the average weight loss was17,5% and the average loss of overweigh 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. 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

Prevalence and risk factor of renal dysfunction induced by bacterial infection other than spontaneous bacterial peritonitis in patients with cirrhosis

Deterioration of renal function in cirrhotic patients with spontaneous bacterial peritonitis [SBP] is a predictor for inhospital mortality. However, the clinical significance of renal dysfunction during bacterial infection other than SBP is unknown. To investigate the prevalence and clinical significance of renal dysfunction due to bacterial infections other than SBP in patients with liver cirrhosis. Retrospective data from in-patients with bacterial infections other than SBP were analyzed. Eighty-two patients were recruited for the analysis. Infection was located in urinary tract [41.5%], pneumonia [34.1%], biliary tract [3.7%], cellulitis [6.1%], gastrointestinal tract [4.9%] and bacteremia of unknown origin [9.7%]. Renal dysfunction developed in 40 patients [48.8%], of which 13 patients had irreversible renal dysfunction. In the univariate and multivariate analysis, the initial MELD score, neutrophil count, bilirubin, and blood pressure were significant risk factors for renal dysfunction. The prevalence of renal dysfunction during bacterial infection other than SBP in patients with liver cirrhosis was 48.8%, and its development was related to the severity of the liver disease. Occurrence of irreversible renal dysfunction seemed to affect the prognosis of these patients

[Factors predicting mortality in infected hospitalized cirrhotics patients: about 97 cases]

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. To determine the predictive factors of hospital mortality in cirrhotic infected patients. 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. 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 micro mol/l and creatinin level more than 120 micro mol/l was independent factors predicting mortality. 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]

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. To describe the epidemiological, clinical and therapeutic features of HCC. 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. 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 imaging and alphafetoprotein in most cases [95%].84 patients [83.2%] had and 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 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. In the majority of the cases, HCC was diagnosed at an advanced stage and treatment was only symptomatic

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

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. 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. 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. 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

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

[Prevalence and risk factors of thromboembolic complications in inflammatory bowel disease]

Patients with inflammatory bowel disease [IBD] are at increased risk of thromboembolic complications [TEC], which represent an important cause of morbidity and mortality. To assess the prevalence and risk factors of TEC in patients with IBD. 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. 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 31years [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. 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

[Correlation between liver biopsy and fibrotest in the evaluation of hepatic fibrosis in patients with chronic hepatitis C]

To assess the diagnosis value of Fibrotest in comparison with liver biopsy, for the evaluation of hepatic fibrosis in patients with chronic hepatitis C. This prospective study included in 2 years [2006-2007], consecutive patients with chronic hepatitis C native to treatment. Fibrotest and liver biopsy were performed. Receiver operating characteristics [ROC] curves, the sensitivity, specificity, positive and negative predictive values were used to assess the diagnostic value of Fibrotest in comparison with the METAVIR classification. We recruited a total of 65 patients: 28 males and 37 females [mean age: 50 years]; 92% of the patients had genotype 1. The histological fibrosis results were: 3. 1% F0; 24. 6% Fl; 32. 3%F2; 29. 2%F3 and 10.8%F4. The diagnostic value of Fibrotest in the detection of significant fibrosis [F2-F4] was 0.87. A score >0.5 has a sensitivity of 85.1%, a specificity of 72.2%, a positive predictive value of 88. 9%, and a negative predictive value of 65%. The diagnostic value of Fibrotest in the detection of cirrhosis [F4] was0.85. There were 13/65 cases of discordance [20%] for fibrosis, 4 cases were attributed to biopsy and 6 cases to Fibrotest. The discordance was unexplained in 3 cases. The size of biopsy<15mm [OR=2. 82, 95% CI, 1.3-6.07; p=0.008] and the stage of fibrosis F0, F1, F2 [OR= 3.35, 95% CI, 1.1-10.2; p=0.03] were considered as risk factors of discordance in multivariate analysis. This prospective study confirmed the good diagnostic value of Fibrotest as compared with the histological analysis of liver biopsy

[Auto immune hepatitis type 1 triggered by cytomegalovirus infection]

Autoimmune hepatitis is chronic and uncommon disease. The pathogenesis is a complex process. Several triggers for autoimmunity in predisposed individuals. Report a new case. We report a case of 17-year-woman presented with autoimmune triggered by cytomegalovirus infection. Cytomegalovirus induced autoimmune hepatitis has not been reported previously. Evolution was favourable under antiviral treatment, corticosteroid and azathioprine

Hepatocellular carcinoma with sarcomatous change

Hepatocellular carcinoma [HCC] with sarcomatous change is an uncommon neoplasm with a poor prognosis. To report a new case. A 72-year-old man presented with abdominal right upper quadrant pain. The diagnosis of cirrhosis was suspected on clinical and biochemical data. On abdominal computed tomography, the mass was not enhanced in the arterial phase and exhibited peripheral enhancement during portal phase which persisted in the delayed phase. The serum alpha-fetoprotein was 500 ng/ml but since the imaging features were not typical of ordinary HCC, percutaneous liver biopsy was performed and confirmed the diagnosis of HCC with sarcomatous change. Except for liver biopsy, no diagnostic method could distinguish between sarcomatous and ordinary HCC

Transverse myelitis associated with chronic viral hepatitis C

HCV infection could cause several extra hepatic diseases including mixed cryoglobulinemia, Peripheral neuropathy is the most common complication of mixed cryoglobulinemia. In addition to cryoglobulinemia's neuropathy, transverse myelitis had been related to had infection. But causality of this association is not clearly established. A 55-year-old man presented with motor deficiency in lower extremities and urinary retention Neurological exams showed a spastic paraparesis and proprioceptive ataxia. Spinal MRI revealed a contrast enhancing signal abnormality within the spinal cord extending from Levels C3 to CS. Serology hepatitis C and viremia were positive. Clinical diagnosis of acute demyelinating sensorimotor polyneuropathy associated to chronic hepatitis C was etablished. Screening of HCV infection must be done in patients with transverse myelitis and no clear aetiology

[Nephrogenic ascites: an exceptional diagnosis. about one case]

Nephrogenic ascites is a clinical entity that manifests as refractory and exsudative ascites with unknown etiology in patients with end stage renal disease and often undergoing hemodialysis. This entity presents in practice many diagnostic and therapeutic difficulties. The aim of this study is to focus on these difficulties through a new observation. We report one case of nephrogenic ascites in chronic renal failure related to an idiopathic neurologic bladder. It's a 38 years old patient on hemodialysis for three years who consulted for exsudative ascites with a low rate of leucocytes. We conclude that nephrogenic ascites is rare. Its diagnosis is an exclusion diagnosis based on exclusion of other causes of ascites, particularly exsudative forms with low leucocytes rate. Its management is based essentially on renal transplantation and its prognosis is very poor
