Value of water enema computed tomography in elderly symptomatic patients.

BACKGROUND AND STUDY AIMS: Colonoscopy remains the gold standard for the examination of the colon. However, its use in the elderly is not well tolerated, and there is often a need for general anaesthesia, thus increasing the risk, especially if there are co-morbidities. Water enema computed tomography has been suggested to be a satisfactory alternative as a non-invasive, fast and effective means for the diagnosis of colorectal supra-centimetric lesions. The aim of our study was to assess the performance of water enema computed tomography as first-line examination by calculating its negative predictive value (NPV) for the diagnosis of supra-centimetric lesions in symptomatic elderly referred to colonoscopy. PATIENTS AND METHODS: This was a prospective study including 57 symptomatic patients older than 65 years. All patients were explored by water enema computed tomography at first, followed by colonoscopy, and responded to a questionnaire on the tolerance to the preparation and both procedures. RESULTS: The mean age of patients was 73 years. The M:F sex ratio was 1.59. The most frequent indication for colonoscopy was bowel disorders associated with abdominal pain (30%). Water enema computed tomography allowed the diagnosis of tumours (n = 2), polyps (n = 6), diverticulosis (n = 7), inflammatory wall thickening (n = 1) and extra-colic lesions (n = 28). NPV of water enema computed tomography for supra-centimetric lesions was 96.5%. Sensitivity and specificity were 87.3% and 98%, respectively. However, for sub-centimetric lesions, water enema computed tomography had a low sensitivity estimated at 6%, specificity at 89.9%, positive predictive value at 91.9% and NPV at 27.7%. CONCLUSION: Water enema computed tomography has proven to be a valuable and non-invasive method indicated as a first-line examination in case of colonic symptoms in the elderly to diagnose supra-centimetric lesions.

Gastric Schwannoma: A Case Report.

Schwannomas are generally benign, slow growing tumors. They are rarely observed in the gastrointestinal tract with the most common site being the stomach. These tumors are usually asymptomatic. The preoperative diagnosis via endoscopy is a challenging issue due to the difficulty of differentiation from other submucosal tumors. A 54-year-old woman presented with epigastric pain persisting for the last 10 months. Upper endoscopy revealed an elevated submucosal mass of the gastric antrum. The overlying mucosa was normal. Biopsy specimens yielded only unspecific signs of mild inactive chronic inflammation. Endoscopic ultrasound examination noted a hypoechoic homogeneous mass lesion located in the gastric antrum. The mass appeared to arise from the muscularis propria, and there was no perigastric lymphadenopathy. A contrast-enhanced computed tomography scan identified a homogeneous round mass and arising from the antrum of the stomach. Submucosal tumor was suspected and surgical intervention was recommended. The patient underwent an elective laparoscopic partial gastrectomy. The histopathologic features and immunohistochemical-staining pattern were consistent with a benign gastric schwannoma. Our patient shows no recurrence with a follow-up of one year. The definitive diagnosis of gastric schwannomas requires immunohistochemical studies. Complete margin negative surgical resection, as in this case, is the curative treatment of choice. The clinical course is generally benign.

Surgical treatment of Crohn's disease: indications, results and predictive factors of recurrence and morbidity.

BACKGROUND: Crohn's disease management represents a major problem in gastroenterology and general surgery because it affects young subjects and has a major impact on their quality of life. The aims of our study were to identify the indications for surgery in Crohn's disease, the results and the complications of surgery in our series, and to identify possible predictive factors of recurrence and postoperative morbidity. METHODS: A retrospective descriptive study including 38 cases of patients with Crohn's disease who underwent surgical treatment in the department of surgery in Mongi Slim Hospital, during the period between January 1992 and December 2011 was performed. RESULTS: The occurrence of stenosis was the most common indication for surgical treatment in Crohn's disease in our series, and ileocecal resection was the most performed surgery. Twenty six patients (58%) received maintenance therapy after surgery. Twenty two patients relapsed and 13 had surgical management for recurrence. In univariate analysis, predictive factors of post operative morbidity in our study were leukocytosis, penetrating phenotype and intraabdominal sepsis. Ileocecal location was the only factor that significantly improved the incidence of recurrence. In multivariate analysis, only penetrating phenotype was a predictive factor or post operative morbidity. CONCLUSION: Despite the development of medical treatment, surgical treatment keeps large indications for the management of complications of Crohn's disease. The surgery should be an alternative to immunosuppressive therapy. Currently, prevention postoperative recurrence is well codified, reducing the risk of complications.

Complete radiological response after sorafenib treatment for advanced hepato-cellular carcinoma.

INTRODUCTION: Sorafenib, an oral multikinase inhibitor, has recentlybeen shown to improve overall survival in patients with advanced hepatocellular carcinoma (HCC) but only a handful of reports of complete remission on sorafenib have been issued. CASE REPORT: We report an intriguing case of advanced HCC complicating HCV infection with cirrhosis, in which the patient achieved complete remission by prolonged administration of sorafenib. CONCLUSION: Identifying factors that could be associated with good response to this therapy are needed.

Percutaneous treatment versus hepatic resection for the treatment of small hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma is the first liver tumor worldwide. Therefore, it is a matter of debate whether surgical treatment or percutaneous treatment should be preferred for the treatment of patients with small hepatocellular carcinoma. The aim of our study was to compare the long-term outcome and the survival between surgically and percutaneously treated small hepatocellular carcinomas. MATERIAL AND METHODS: A retrospective study was performed in the department of hepatology during a period of 2009-2012. The study included all patients carrying small hepatocellular carcinoma which were divided in: group 1 including patients who underwent surgical treatment, and group 2 including patients who underwent percutaneous treatment. RESULTS: Among the 63 patients who were diagnosed for hepatocellular carcinoma, 28 carried a small hepatocellular carcinoma with a mean age of 63 years and sex-ratio of 0.64. Etiology of cirrhosis was viral in 96% cases. Surgical treatment (hepatic resection) was performed in 54% cases while percutaneous treatment was proposed for 46%: radiofrequency ablation in 69% and alcoholic injection in 31%. No major complications for both surgical and percutaneous treatment occurred in our study. The corresponding 6 months and 1- year overall survival rates for the surgical resection group and the percutaneous treatment group were 100%, 100%, 20%, and 52%, respectively (p=0,04). The disease free survival were not significantly different. CONCLUSION: Our results showed the efficacy and safety of percutaneous ablation treatments (radiofrequency ablation and ethanol injection) in patients with small hepatocellular carcinoma.

Quality indicators for colonoscopy in a Tunisian endoscopy unit.

BACKGROUND: Colonoscopy is a powerful tool for prevention and early diagnosis of colorectal cancer. However, the effectiveness of colonoscopy is dependent on the quality of the procedure, which is assessed by a number of key quality indicators. Among them, cecal intubation and adenoma detection rate are historically the most commonly used indicators of quality of colonoscopy. The aim of our study was to evaluate these two indicators of quality of colonoscopy in a Tunisian endoscopy center. METHODS: We conducted a retrospective study from January 2009 to March 2013. Data were collected from colonoscopies reports. Demographic data, indication of the procedure, and endoscopic diagnosis were collected. The quality of bowel preparation was subjectively classified at the time of the examination by each endoscopist as good, fair, or poor. Procedure related quality indicators considered for analysis were: cecal intubation rate (CIR) and polyp detection rate. RESULTS: During the period of the study, 859 colonoscopies were performed without sedation. The average age was 54.76 ± 17.5 years. Males represented the majority of our population (50.2%). Colic preparation was judged good, fair and poor in respectively 24 %, 61% and 15% of cases. The cecal intubation rate was 61.1 %. Causes of incomplete colonoscopy were especially poor preparation (47.3%) and poor tolerance (34.4%). Univariate analysis disclosed 3 predictive factors of CIR : the quality of bowel preparation (good vs fair or poor( (67.2 % vs 31.3%, p = 0.0001,OR: 4.5, 95% CI: 3.3-6), the screening indication (72.9% vs 60.1% , p = 0.03, OR: 1.7, 95% CI: 1-3) and the presence of alarming signs (55% vs 43%, p=0.04; OR: 1.1, 95% CI:0.9-2.5). By multivariate analysis, the factors influencing independently the CIR were the quality of bowel preparation (p=10-3, OR=2.23, 95% CI: 1.47-3.3) and the screening indication (p=0.02, OR: 1.9, 95% CI: 1.1-3.4). The polyp detection rate was 21% and was correlated, in univariate analysis with: age over 47 years (p=10-3, OR:3.2, 95 % CI:2-4.9), male gender (25.1% vs 16.8%, p=0.001, OR:2.36, 95% CI: 1.4-4), the quality of the preparation (26.5% vs 19.1%, p=0.03 OR:1.4, 95% CI:0.9 -2), the presence of colorectal cancer (50.9% vs 18.2%, p=0.0001, OR:4.6, 95% CI: 2.6-8) and the screening indication (35.7% vs 19%, p=0.001 OR: 2.36, 95% CI: 1.4- 4). By multivariate analysis, 3 independent factors associated with polyp detection rate were identified: age over 47 years (p=10-3, OR: 3.5 95% CI:2-5.9), bowel preparation (p=10-3 OR=5, 95% IC:2.7-9.6) and the screening indication( p=0.01, OR 2.5, 95% IC 1.4-4.7). CONCLUSION: In our cohort, the quality of bowel preparation, tolerance of the procedure, age and the indication of colonoscopy were significantly associated with the indicators of quality. Bowel preparation and tolerance are targets on which we should act to improve performance.

Budd-Chiari Syndrome: An Unusual Presentation of Multisystemic Sarcoidosis.

Sarcoidosis is a multisystem granulomatous disease of unknown origin. All organs may be affected. Liver involvement is common but it is rarely symptomatic. Only a few cases of Budd-Chiari syndrome (BCS) secondary to a hepatic sarcoidosis have been described so far. We describe a case of multisystemic sarcoidosis presenting with BCS. A 42-year old female was referred to our department for chronic and anicteric cholestasis. Laboratory and imaging investigations disclosed features of chronic BCS associated with multisystemic sarcoidosis. The positive diagnosis was based on microscopic features, which showed hepatic, gastric and cutaneous non-caseating granulomas. Screening for an underlying thrombophilic disorder was negative. The diagnosis of BCS complicating hepatic sarcoidosis was the most likely. She was put on corticosteroids and anticoagulation therapy. To our knowledge, few cases of sarcoidosis-related BCS have been reported in the literature. In addition to being an uncommon presentation of sarcoidosis, this case illustrates the importance of recognizing an unusual cause of BCS and its therapeutic difficulties.

No major complications for both surgical and percutaneous treatment occurred in our study. Overall survival was significantly lower in the surgical resection group. The corresponding 6 months and 1-year overall survival rates for the surgical resection group and the percutaneous treatment group were 100%, 100%, 20%, and 52%, respectively (p=0,04). The disease free survival were not significantly different. CONCLUSION: Our results showed the efficacy and safety of percutaneous ablation treatments which were better than those of surgical treatment in patients with small hepatocellular carcinoma.

Risk factors of psychological disorders in inflammatory bowel disease in a tunisian survey. Results of a cross-sectional study.

BACKGROUND: Little is known in inflammatory bowel disease (IBD) regarding risk factors for psychological distress. The aims of our work were to evaluate the frequency of anxiety and depression among patients with IBD and to determine the factors associated with these psychological disorders in Tunisian patients. METHODS: From June 2012 to April 2013, 60 consecutive patients with IBD answered a questionnaire about psychological and socioeconomic factors and adherence to treatment. In this study we focused the analysis on the characteristics of IBD (type, localization, severity, treatment) and socioeconomic factors (professional, educational, and marital status). Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale (HADS). RESULTS: According to the HADS, 25 patients (41.6%) were anxious while 4 (6.6%) were depressed. Three had anxiety and depression at the same time. Twelve patients had a probable anxiety, 2 patients had a probable depression and 3 patients had a probable depression and anxiety at the same time. By univariate analysis, factors associated with anxiety and depression were: female gender (p<0.03), rent (p<0.03), high school graduation (p<0.009), IBD type ulcerative colitis (p<0.05). By multivariate analysis, independent factors associated with these emotional disorders were: female gender (p=0.005, OR 11.3), the high school graduation (p=0.004, OR 12.1). CONCLUSION: In our cohort, risk factors for anxiety and depression were the high school graduation and IBD type ulcerative colitis. Consequently, psychological interventions would be useful when these factors are identified.

Gender difference in patients with hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma represents the fifth most common cancer worldwide and account for approximately 90% of primary liver cancer. Men have a higher prevalence than women; the sex ratio varies between 2:1 and 4:1, depending on the geographic region. AIM: To determine the influence of gender on the clinicopathologic characteristics and survival of patients with hepatocellular carcinoma. METHODS: A retrospective analysis of medical records was performed in 63 patients with hepatocellular carcinoma and their clinicopathologic features and survival were compared in relation to gender. The data was summarized by descriptive statistics and analysed with SPSS version 11.5. RESULTS: Among these patients, 36 were men (57.1%) with male-to female ratio of 2:1.5, the mean female age was 59.8 years (p=0.054). Serum albumin level was significantly lower in women (p=0.0061).The average size of the tumor was 45.8mm and the difference was not significant (p=0.638). Hepatocellular carcinoma was significantly more prevalent among 16 men with post viral B cirrhosis (p=0.04). The main reason for therapeutic abstention was multifocal character of the hepatocellular carcinoma. The median survival time (6.52 months) was not different between the 2 groups. CONCLUSION: At diagnosis, men were younger than women. The viral C etiology was statistically more frequent in women than in men. Hepatocellular carcinoma was more aggressive in male but median survival time was not significant between groups. Screening and early treatment can limit this problem.

Retained common bile duct stones after endoscopic sphincterotomy: temporary and longterm treatment with biliary stenting.

BACKGROUND: Endoscopic extraction of biliary tract stones is safe and effective. When the procedure is not successful, the use of a biliary stent can be a solution. AIM: To prospectively analyse the usefulness of a stenting in management of biliary obstruction due to choledocolithiasis. METHODS: All patients referred to our endoscopic unit from January 2005 to January 2008, for management of bile duct stone are studied. We included patients subjected to an endoscopic insertion of a biliary stent. RESULTS: Of 414 patients with choledocolithiasis, 51 failed to have their ducts cleared with the first endoscopic retrograde cholangiopancreatography (ERCP): 25 patients (6%) were referred to surgical stone removal. Twenty six consecutive patients had endoscopic insertion of a 10 Fr biliary stent: There were 12 men and 14 women ranging in age from 35 to 102 years (median age 68 years). The indications for stent placement in common bile duct stone were mainly the endoscopic portal hypertension, elderly patients or with a short life expectancy. Twenty four patients (88%) are symptom free after stenting. Six patients (23%) had duct clearance after a median of 3 sessions at a mean of 13 months (range 3-48 months). In 3 patients endoprosthesis was inserted as a permanent therapy of biliary obstruction. Cholangitis occurred in 5 patients, early in two cases and later at a mean of 18 months (range 6-24 months) in 3 patients and was managed endoscopically by stent replacement and fluid antibiotics. CONCLUSIONS: These data favor temporary use of biliary endoprostheses in patients with endoscopically irretrievable bile duct stones until the definitive treatment is carried out. However, as a permanent therapy, late complications occur in many patients and the risk increases proportionally in time. Therefore, permanent biliary stenting should preferably be restricted to patients unfit for elective treatment at a later stage and with a short life expectancy.

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.

[Survival in cirrhosis]. / Survie chez le Cirrhotique Tunisien.

BACKGROUND: Assessment of prognosis in patients with cirrhosis is important so as to plan their management. AIM: To determine the survival rates and to identify indicators associated with shorter life expectancy in Tunisians patients with cirrhosis. METHODS: This is a retrospective study of in-patients with cirrhosis during a 5-years period. We studied clinical and biochemical characteristics of all patients and the occurrence of decompensation or complication. The overall survival, mortality rate and causes of death were reviewed. Univariate and multivariate analysis was performed on all variables to identify parameters associated with a lower life expectancy. RESULTS: We studied 222 patients (60% females) with a mean age of 60 years. Mean follow up was 22 months. The overall survival was 52.5% at 5 years. With univariate analysis, 10 variables were associated with a poor prognosis: male gender, decompensation at admission, Child-Pugh C, esophageal varices, hypertensive gastropathy, occurrence of spontaneous bacterial peritonitis, hepatic encephalopathy, hepato-renal syndrome, hepatocellular carcinoma and portal thrombosis. With multivariate analysis, only male gender was independently correlated with survival. CONCLUSION: In our study, male gender was an uncommon parameter that predicts survival in cirrhotic patient. The Child-Pugh score was a good index for assessing the prognosis.

[Psoas abscess as the initial manifestation of Crohn's disease. Report of 3 cases]. / Abcès du psoas révélant une maladie de Crohn. A propos de 3 observations.

BACKGROUND: Psoas abcess complicating Crohn's disease is a rare condition. Diagnosis remains difficult, especially when it is the first sign of Crohn's disease. AIM: We report here 3 patients presenting with psoas abcess as the initial manifestation of the disease, among 118 patients with Crohn's disease seen between 1990 and 2006. CASES REPORT: Symptoms and signs were fever, lower abdominal quadrant pain or tenderness and psoitis. Diagnosis was confirmed in all cases by computed axial tomography. In 2 cases, psoas abcess secondary to a periappendicular abcess or a colonic neoplasm were suspected, and the etiology was made correctly only after operation. Effective therapy included antibiotics, drainage and bowel resection.

[Chylous ascites after pelvic irradiation for urologic malignancy]. / Ascite chyleuse après irradiation pelvienne pour une tumeur maligne de l'urètre.

CASE: A 74-year-old woman had a history of transitional papillary carcinoma of the urethra, treated with brachytherapy and radiation therapy. She was hospitalized for exploration of chylous ascites. After a work-up, we concluded it was due to chyloperitoneum caused by a post-radiation lymphatic opening. Conservative treatment, including a low-fat high-protein diet, together with medium-chain triglycerides, led to the drying of the ascites. DISCUSSION: Development of chylous ascites after radiation therapy requires first of all a search for a tumor recurrence. Nonetheless, radiation induction must be considered; its course is usually benign with good response to conservative treatment.

When will we change treatment in the care of patients with chronic hepatitis B?

BACKGROUND: The treatment by the standard interferon is at present the only treatment recommended in Tunisia in the care of the chronic infection B. PURPOSE: Estimate the biochemical and virological answer of the patients reached by a chronic hepatitis B, treated by standard interferon. METHODS: All the patients, having a chronic hepatitis B confirmed histological, hospitalised in the service of hepatho-gastroenterologie of the hospital Habib Thameur between 1990-2005, were respectively included. The studied parameters were the age, the sex, the transaminases levels meadow and post therapeutic, the viral HVB DNA, the degree of activity and fibrosis according to the score of Metavir. The biochemical answer was defined by the normalization of transaminases at the end of treatment. The virological answer was defined by the seroconversion Ag Hbe for the patients Ag Hbe + and by the negativation of the HBV DNA for all patients. RESULTS: Fifty-one patients of an average age of 31.38 +/- 12.42 years [range: 12-68 years] were included. Twenty-five patients (49%) were treated. Sixteen of them (31%) were Ag Hbe-. The biochemical answer was observed in four cases. A seroconversion was observed in two cases. No negativation of the HBV DNA has been noted. CONCLUSION: The results of the standard interferon in the treatment of the chronic hepatitis B are disappointing in this series. The introduction of new therapeutic molecules adorned necessities in the care of such patients.
