Hepatitis viruses take advantage of traditional practices to increase the burden of hepatocellular carcinoma in Tunisia.

Hepatocellular carcinoma (HCC) is a major public health issue in Africa. In Tunisia, hepatitis B virus (HBV) is known to be an important risk factor for HCC in the south of the country, but the role played by hepatitis C virus (HCV) still remains unclear. The aim of the current case-control study was to identify risk factors for HCC development in the northern part of the country. Clinical and biological data including viral hepatitis status (serological and molecular) and non-infectious risk factors from 73 patients with HCC and 70 control subjects without hepatic diseases were collected. The mean age of the patients was 63 ± 10 years, and the ratio of males to females was 1.1. HCC occurred in cirrhotic liver in 72.0% of the cases. HCV infection was the dominant risk factor (64.3% of cases); the presence of HBV was observed in 53.4% of the cases. Occult hepatitis B and C were implicated, respectively, in 30.1% and 9.6% of the cases. HCV genotype 1b was predominant. Patients originating from western Tunisia formed a homogeneous group, characterized by significantly higher rates of tattoos or scarifications (83%) and HCV infection (80%) than those from other parts of the country. Chronic HCV infection is currently the primary risk factor for HCC in Tunisia; HBV infection remains frequent in its overt or occult infection forms. Traditional esthetic practices apparently contribute to increasing the burden of terminal liver diseases in western Tunisia.

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.

Pancreatic cystic neoplasms.

BACKGROUND: Cystic neoplasms of the pancreas are rare and constitute approximately 0.5% of all pancreatic neoplasms. AIMS: The study was to describe clinicopathological features of pancreatic cystic tumors. PATIENTS AND METHODS: In our retrospective study, we reviewed 10 cases of pancreatic cystic neoplasms that were diagnosed at the pathology department of Mongi Slim hospital over a 14-year period (2000-2013). We adopted the latest World Health Organization (WHO) classification (2010) in grouping all tumors. RESULTS: There were one male and nine female patients (sex ratio M/F = 1:9) aged between 21 and 68 years (mean = 37.5 years). The most common clinical presentation was epigastric and abdominal pain (n = 6) followed by vomiting (n = 3). Abdominal computed tomography (CT) scan disclosed a cystic lesion of the pancreas ranging in size between 2 and 10 cm (mean = 6.75 cm). All patients underwent surgical treatment. Histopathological examination of the surgical specimen established the diagnosis of solid pseudopapillary neoplasm (n = 2), serous cystic neoplasm (n = 2), mucinous cystadenoma (n = 4), mucinous cystadenocarcinoma (n = 1), and intraductal papillary mucinous neoplasm with invasive carcinoma (n = 1). CONCLUSION: Better understanding of pancreatic cystic neoplasms is essential for clinicians to make accurate diagnosis and to provide the best management for patients.

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. 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 53.5% cases while percutaneous treatment was proposed for 46.5%: radiofrequency ablation in 69% and alcoholic injection in 31%. 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.

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.

Colectomy for Porto-Systemic Encephalopathy: Is it Still Topical?

Hepatic encephalopathy (HE) is a common long term complication of porto-systemic shunt. We report herein the case of a 59-year-old man with Child-Pugh A cirrhosis treated successfully 9 years earlier with distal splenorenal shunt for uncontrolled variceal bleeding. In the last year, he developed a severe and persistent hepatic encephalopathy secondary to the shunt, which was resistant to medical therapy. As liver transplantation was not available and obliteration of the shunt was hazardous, we performed subtotal colectomy in order to reduce ammonia production. This therapeutic option proved successful, as the grade of encephalopathy decreased and the patient improved. Our experience indicates that colonic exclusion should be considered as an option in the management of HE refractory to medical treatment in highly selected patients when liver transplantation is not available or even as a bridge given the long waiting time on lists.

First multicenter study for risk factors for hepatocellular carcinoma development in North Africa.

AIM: To assess the role of the major risk factors for hepatocellular carcinoma (HCC) development in the western part of North Africa. METHODS: A multicenter case control study was conducted in Tunisia, Morocco and Algeria in collaboration with Pasteur Institutes in these countries. A total of 164 patients with HCC and 250 control subjects without hepatic diseases were included. Prevalences of HBsAg, anti-hepatitis C virus (HCV) and diabetes were assessed. HCV and HBV genotyping were performed for anti-HCV and HBsAg positive patients. RESULTS: The mean age of patients was 62 ± 10 years old for a 1.5 M:F sex ratio. Sixty percent of HCC patients were positive for anti-HCV and 17.9% for HBsAg. Diabetes was detected in 18% of cases. Odd ratio (OR) and 95% confidence intervals (CI) were 32.0 (15.8 - 65.0), 7.2 (3.2 - 16.1) and 8.0 (3.1 - 20.0) for anti-HCV, HBsAg and diabetes respectively. Multivariate analysis indicated that the three studied factors were independent. 1b HCV genotype and D HBV genotype were predominant in HCC patients. HCV was the only risk factor significantly associated with an excess of cirrhosis (90% vs 68% for all other risk factors collectively, P = 0.00168). Excessive alcohol consumption was reliably established for 19 (17.6%) cases among the 108 HCC patients for whom data is available. CONCLUSION: HCV and HBV infections and diabetes are the main determinants of HCC development in North Africa. An active surveillance and secondary prevention programs for patients with chronic hepatitis and nutrition-associated metabolic liver diseases are the most important steps to reduce the risk of HCC in the region.

[Epidemiological study, pathologic evaluation and prognostic factors of colorectal mucinous vs non-mucinous adenocarcinoma (a series of 196 patients)]. / Etude épidémiologique, anatomopathologique et évaluation des facteurs pronostiques des adénocarcinomes colorectaux mucineux vs non mucineux. (A propos d'une série de 196 patients).

BACKGROUND: Colorectal carcinoma is one of the main causes of cancer death in the worldwide with a decrease survival rate in relationship with a later diagnosis of advanced disease. AIMS: This study highlights the particular epidemiological, clinicopathological and immunohistochemical colorectal cancer profile. Indeed, our results differ markedly from that reported in the literature. METHODS: We underwent a retro and prospective study interesting 196 patients with colorectal carcinoma diagnosed in the pathological and cytological laboratory of Mongi Slim Hospital (Tunisia). Age at diagnosis, mode of presentation, sex, tumour location, macroscopic and histological features, TNM and Astler Coller stage were assessed and evaluated. RESULTS: We report here a particular epidemiological pattern which is characterised by younger age of the patients, equally distribution between men and women, predominant sporadic carcinomas and preponderance of rectosigmoid location. The poorer degree of differentiation and mucinous subtype are correlated with an advanced stage. It is also correlated with more frequent vascular embols, neural invasion and metastatic nodes. Furthermore, immunohistochemical analysis of galectin-3 showed a significant difference between mucinous and non mucinous adenocarcinoma. CONCLUSION: Based on the presented data, the epidemiological pattern and the anatomic distribution especially in the rectosigmoid region suggest diet and lifestyle to be primordial risk factors of colorectal tumorigenesis.

[P73 gene expression in colorectal adenocarcinoma: a prognostic or etiopathogenetic factor?]. / Expression de p73 dans l'adénocarcinome colorectal: serait- elle un facteur pronostique ou etiopathogénique?

BACKGROUND: The p73 gene encodes a nuclear protein that is highy homologous to p53. p73 also shares some common functions with p53 protein indicating that p73 gene is a p53-like tumor suppressor. AIM: In this study, we examined by immunohistochemestry the p73 expression on 120 cases of colorectal carcinomas and evaluated its implication in carcinogenesis. METHODS: Retrospective study. RESULTS: The results show an increase of intensity and distribution of p73 in common adenocarcinoma from the normal mucosa, to primery tumors and to metastases. However, in mucinous adenocarcinomas, immunostaining of p73 decrease in primary tumor and completely diseappears in isolated cells and metastases compared with matched normal mucosa. These observations are further reinforced by the fact that in adenocarcinoma with mucinous component less than 50%, the positivity of p73 persist in well-differentiated areas and dramatically decreases or completely deseappears in mucinous areas. CONCLUSION: In conclusion, p73 would be a prognosic marker for the common adenocarcinomas and an ethiopathogenic factor for the mucinous subtype.

[Postoperative analgesia after laparoscopic cholecystectomy: comparison of the preoperative administration of celecoxib with paracetamol?]. / Analgesie postoperatoire pour cholecystectomie sous coelioscopie: comparaison de l'administration preoperatoire du celecoxib et du paracetamol.

OBJECTIVE: The goal of this study was to evaluate the preventive analgesic effectiveness of paracetamol and celecoxib in laparoscopic cholecystectomy. METHODS: Randomized prospective study was undertaken, 75 patients of class ASA I and II were included, divided into three groups: P (Paracetamol 1000 mg), C (Celecoxib 200 mg) given orally one hour before induction and group T (without preoperative analgesia). The VAS at rest and effort was noted on arrival in the recovery room then with regular intervals (T(30mn) to T(h24). A morphine titration was carried out during the first 12 postoperative hours. Hemodynamic parameters, Ramsay score and the adverse effects were noted. RESULTS: The three groups were comparable for the demographic data, the duration of anesthesia and peroperative morphine consumption. The evolution of VAS scores shows a significant difference between the groups P and T with the effort of cough at t24h (p = 0.04), and between the groups C and T at postoperative T 4h (p = 0.016). In our study the group C consumed to a significant degree less morphine 5.44 +/- 3.00 Mg against 7.83 +/- 4.00 Mg for the group P (p < 0.03) and 8.04 +/- 3.00 Mg for the group T (p < 0.008). CONCLUSION: The administration of 200 Mg of celecoxib in the preoperative period of a laparoscopic cholecystectomy allows a significant decrease in morphine consumption in the postoperative period and a reduction in the scores of the VAS at rest and at the effort of cough compared to the groups which received only one placebo or paracetamol.

[Phlegmonous appendicitis revealed by pyogenic liver abscesses]. / Abces bacteriens du foie revelant une appendicite phlegmoneuse.

BACKGROUND: Pyogenic liver abscesses are rare and severe. Early diagnosis and treatment lead to a better prognosis. Biliary cause of liver abscesses is the most frequent. Portal origin is secondary to a portal bactremia. Appendicitis was the most cause of portal infection, but actually, diverticulitis is most common. AIM: the aim of this study was to report a new case of pyogenic liver abscesses secondary to phlegmonous appendicitis. CASE REPORT: We report a case of 47 years old man presented with fever and weight loss without abdominal pain. Laboratory investigations show signs of inflammation with high leukocyte and neutrophile rates. The diagnosis of liver abscesses was made on abdominal ultrasound and tomodensitometry witch shows also an inflammatory appendix. The outcome was good after antibiotics associated with percutaneous drainage of abscesses and laparoscopic appendectomy witch found a phlegmonous appendix. One month later, the CT scan showed a markedly decrease of the size of the abscesses.
