Endoscopic removal of a transgastric migrated textiloma: a case report.

Aim: Abdominal textiloma is an uncommon postoperative complication which can result in a fistula with luminal migration in the digestive tract. Surgery has been the mainstay method for textiloma removal; however, removal of retained gauze by upper gastrointestinal endoscopy is possible avoiding reoperation. Case report: We report a case of an abdominal textiloma in a 38-year-old male, which migrated into the stomach and was extracted by upper endoscopy. Conclusion: Endoscopic extraction after a luminal migration of the abdominal textiloma in the digestive tract facilitate its management and could avoid surgery.

The diagnosis of abdominal textiloma must be considered in front of unexplained symptoms in patients with a surgical history. Surgery has been the mainstay method for textiloma removal; however, endoscopic removal may be the best option which avoids reoperation. We report a case of an abdominal textiloma in a 38-year-old male, which migrated into the stomach and was extracted by upper endoscopy.

Clinical practice standards for colonoscopy.

Colonoscopy is considered as the most effective tool for preventing, screening, and diagnosing colorectal lesions. Effectiveness of colonoscopy was identified as a major priority, and it strictly depends on quality measures. Therefore, international guidelines were formulated on quality indicators for colonoscopy, aiming to reduce the rate of interval cancers related to missed lesions during colonoscopy. Quality indicators are divided into 3 time periods: preprocedure, intraprocedure, and postprocedure.  The main pre-procedural indicators are the assessment of the appropriateness of indication of colonoscopy and the prescription of adequate bowel preparation during a consultation prior to colonoscopy. Per-procedural criteria include all technical aspects of the procedure, which are "endoscopist-dependent" factors, particularly cecal intubation, detection of adenomas and withdrawal time. The main post-procedure indicators are the rate of complications, patient experience and optimal surveillance intervals following removal of colorectal polyps. The implementation of key performance measures in endoscopy practice is increasingly important as it can help improving our care of patients and optimize outcomes. In this review, the "Club d'endoscopie digestive" (CED) presented a summary of the main colonoscopy quality indicators, and suggested recommendations that took into account the particularities of our local conditions.

Does Anemia Have a Potential Effect on Type 2 Hepatorenal Syndrome?

Background/Aims. Hepatorenal syndrome (HRS) is a form of functional renal failure arising in advanced cirrhosis and is characterized by a poor survival rate. Anemia is frequently observed during the clinical course of cirrhosis. Our study aimed to investigate the hematologic findings in patients with cirrhosis to determine the effects of anemia on renal functions in type 2 HRS and if it was a potential aggravating factor. Materials and Methods. This prospective study, in which all consecutive patients with cirrhosis were enrolled, was performed at a tertiary-level hospital (Military Hospital of Tunis) from January 2019 to June 2019. A total of 9 patients with HRS fulfilled the type 2 HRS diagnostic criteria, and 41 patients with cirrhosis without HRS were included. All data regarding patients were obtained from the medical record. Demographic data, routine hemograms, biochemical, and urinary test results were collected. Models of end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) scores were calculated. Results. The most common etiology of cirrhosis was viral hepatitis (66%). According to the CTP score, 23 patients were in the CTP-A stage, 13 in the CTP-B stage, and 14 patients were in the CTP-C stage. Patients with type 2 HRS had significantly lower hemoglobin levels compared with non-HRS stable cirrhosis patients. As hemoglobin levels decreased, renal function worsened on patients with type 2 HRS. Patients with lower hemoglobin levels had poor prognosis and survival compared with patients with higher hemoglobin levels. Logistic regression analysis showed that lower hemoglobin levels and higher MELD and CTP scores were statistically significant for an onset of type 2 HRS. Conclusion. Renal dysfunction is a frequent complication in patients with end-stage chronic liver disease. The role of anemia in aggravating HRS in patients with cirrhosis is explained by hypoxia that can lead to microcirculatory renal ischemia. Other studies are required to determine if anemia is a precipitant factor for HRS or not.

Digestive manifestations in COVID-19: Prevalence and prognostic impact.

BACKGROUND: Since its declaration in december 2019, a novel coronavirus, the SARS-CoV-2 was rapidly responsible for a major pandemic. COVID-19 is mainly manifested by respiratory symptoms,however, digestive manifestations have been reported, raising the hypothesis of the viral digestive tropism. AIMS: Specify the digestive manifestations due to the SARS-CoV-2, and their impact on the disease prognosis and describe the COVID-19 effect in patients with underlying digestive disease. METHODS: Ageneral review of the medical literature was conducted via Medline® database, through various combinations of the following keywords :SARS-CoV-2, COVID-19, gastrointestinal tract, digestive system, inflammatory bowel diseases, liver, liver injury, chronic liver disease, neoplasms. The most relevant articles were selected. RESULTS: The SARS-CoV-2 tropism for the digestive tract has been confirmed by the identification of the enterocyte as a target cell of the virus. Viral particles and RNA detection in stool of infected patients has raised the potential for feco-oral transmission of the virus. Gastrointestinal manifestations were frequent and may even be revealing or isolated. Diarrhea was the most characteristic symptom. Frequent liver involvement is associated with a more severe form of the disease. Patients with digestive cancer and chronic liver disease are at risk for a severe form of SARS-CoV-2 infection. CONCLUSION: The clinician is required to know this type of manifestations in order to limit the delay in diagnosis and to better assess the prognosis.

Genome-wide association of IL-28B with response to pegylated interferon-alpha and ribavirin therapy for chronic hepatitis C in a Tunisian population.

BACKGROUND:   A polymorphism upstream of interleukin (IL)-28B was recently identified to be associated with a 2-fold difference in sustained virologic response (SVR) to pegylated interferon-alpha and ribavirin therapy in a large cohort of treatment-naive, adherent patients with chronic hepatitis C (CHC) virus genotype 1 (HCV-1) infection. AIM: We sought to confirm the polymorphism's clinical relevance by intention-to-treat analysis evaluating on-treatment virologic response and SVR. METHODS: We perform a prospective study in gastroenterology unitof tunis'military hospital in collaboration with immunology unit, military center of blood transfusion and laboratory of biochemistry of childrens' hospital of Tunis. HCV patients were genotyped as CC, CT or TT at the polymorphic site rs12979860 and TT, TG or GG at the polymorphic site rs8099917. Viral kinetics and rates of rapid virologic response (RVR, week 4) and SVR were compared by IL-28B type in a tunisian population. RESULTS: 154 patients including 80 healthy blood donors(sexratio: 1, mean age: 40.35 ±10.15 years) and 74 patients treated for CHC (39 men and 35 women; mean age = 51.7± 9.4 years) were enrolled. 35.6% of patients were genotyped as CC at the polymorphic site rs12979860 and 69.1% as TT at the polymorphic site rs8099917. The CC IL-28B type at rs12979860 was associated with a greater likelihood of SVR (77% vs 31.9%; p<0.001; OR: 7.11 [2.37-21.35]) compared with CT and TT. The CC IL-28B type at rs12979860 wasn't associated with improved of rapid virologic response (RVR). In a multivariate logistic regression model, the rs12979860 CC genotype predicted SVR (p<0.001; OR: 7.11 IC95% [2.37-21.35]). The TT IL-28B type at rs 8099917 wasn't associated with improved RVR and SVR compared with TG and GG. CONCLUSION: In treatment-naive HCV patients treated with pegylated interferon and ribavirin, a polymorphism upstream CC at the site rs12979860 of IL-28B is associated with increased sustained virologic response and effectively predicts treatment outcome.

Cholestatic hepatitis due to Ecballium elaterium ingestion.

Ecballium elaterium is an herbaceous plant belonging to the Cucurbitaceae family. This plant is fairly common in the Mediterranean regions. It is frequently consumed in infusion, mixture of fruit or even in aerosol in cases of fever or flu. This plant is known for its respiratory and ocular toxicity. Hepatotoxicity has never been described in the literature. We report a case of acute cholestatic hepatitis due to Ecballium elaterium in a 39 years old patient, with no past medical history.

[Endoscopic treatment of Zenker's diverticulum with soft diverticuloscope: a first Tunisian experience]. / Traitement endoscopique du diverticule de Zenker par un diverticuloscope souple: Une première expérience Tunisienne.

INTRODUCTION: Zenker's diverticulum is an acquired hernia from the posterior pharyngeal mucosa developed in the pharyngo-esophageal junction. The gold standard for diagnosis is pharyngo-esophageal barium swallow study. Open surgery with cricopharyngeal myotomy has long been the conventional treatment. Actually, endoscopic treatment is an efficient alternative to resolve the problem with shorter surgery duration and less complication. AIM: We report 3 cases of patients with Zenker's diverticulum treated with endoscopic approach in our department between 2013 and 2014. CASE REPORT: There were three men aged 71, 79 and 62 years admitted to our department with symptomatic Zenker's diverticulum. Predominant symptoms were dysphagia and regurgitation. Diverticulotomy with a flexible endoscope was performed for all patients, using argon plasma coagulation in the first case and a needle-knife in the two others. Hemostatic clips were placed at the end of the procedure. There was no complication in the last two cases. Perforation at the left lateral side of the cervical diverticulum was observed in the first patient solved by diet and antibiotics. We performed a pharyngo-esophageal barium swallow study before and after the intervention in all patients showing significant regression of the diverticulum and we observed a complete regression of clinical symptoms. CONCLUSION: Treatment with endoscopic approach using a flexible endoscope and a diverticuloscope for good exposure of the diverticulum is a safe procedure offering a rapid improvement of symptoms with a lower risk of complications and a shorter duration of hospitalization compared to surgical treatment.

Argon plasma coagulation in the management of symptomatic gastrointestinal angiodysplasia: experience in 69 consecutive patients.

BACKGROUND: Gastrointestinal angiodysplasias are associated with a high bleeding risk. AIM: to evaluate the efficiency of argon plasma electrocoagulation in the treatment of gastrointestinal angiodysplasia and to identify predictive factors of success of this technique. METHODS: Retrospective study of patients with bleeding gastrointestinal angiodysplasia treated with argon plasma electrocoagulation in the digestive endoscopy unit of the military hospital in Tunis between January 2000 and December 2011. RESULTS: 69 patients with a mean age of 68.7 years were included.The endoscopic treatment resulted in a rise in hemoglobin value from 7.3 to 9.3 g/ dl (p = 0.0001) and a decrease of transfusion requirements from 2.5 to 0.1 units of packed red cells (p <0.0001). It allowed to avoid surgery for 93.6% of patients with complex medicalhistory. Recurrence of bleeding was observed in 33.3% of patients after a mean time of 12.3 months. In a multivariate analysis, no factors were independently associated with the recurrence of bleeding. The overall survival without rebleeding at 1 and 2 years were 50% and 42% respectively. CONCLUSION: Argon plasma coagulation is an easy, effective and safe treatment of bleeding angiodysplasia. This technique is particularly interesting for patients with multiple medical problems, where surgical treatment could be burdened by significant morbidity and mortality risk.

Predictors of successful endoscopic colonic polypectomy.

BACKGROUND: Endoscopic polypectomy is the technique of choice for resection of colorectal polyps and has a major interest in the prevention of colorectal cancer. The aim of this study was to evaluate the technique, results and tolerance of colonic polypectomy. METHODS: We conducted a retrospective study including 200 consecutive patients with colorectal polyps and who underwent therapeutic endoscopic polypectomy, performed at the endoscopy unit of the Military Hospital in Tunis, between december 2008 and december 2012. RESULTS: Hundred and forty men and 60 women were included. The average age was 58.5 ± 14.5 years. The polyp was unique in more than half of cases. The most frequent location was the sigmoid colon (30.5%). Approximately, » of the polyps was larger than 10 mm. According to the Paris endoscopic classification, 78% of polyps were sessile (Is). Seventy-two percent of polyps were adenomas. Twentyfive per cent of them contained a villous component, 40 % were advanced adenomas and 3% malignant adenomas. Regarding polypectomy, 232 polyps (64%) were treated by the cold forceps, 68 polyps (18.5 %) by the diathermic snare and 63 (17.5 %) by a mucosal resection. Thirty-one percent of polypectomy were fragmented. The evaluation of the efficacy of treatment among adenomas and potentially malignant tumors, had identified 36% of treatment failure. The common independent predictive factor of fragmented resection and treatment failure were the size ≥ 10 mm (p <10-3). Among a total of 363 polypectomies, 23 (6.3%) were complicated, by 11 procedural bleeding, 11 micro-perforations and 1 delayed hemorrhage. The common independent predictive factor of these complications was the size ≥ 10 mm (p <10-3). During following, there were 12 residual polyps (6%), 36 new polyps (18%) and 6 colorectal cancers (3%). The only independent predictive factor of an unfavorable course was the multiplicity of polyps. The colorectal polyps-free survival was 90.2% at 12 months and 88.4% at 24 months. CONCLUSION: The evaluation of colorectal polypectomy in our series had confirmed the effectiveness and the low morbidity of this practice. The polyp size was the only independent predictive factor of both treatment failure and complications.

Screening for viral hepatitis C in a young Tunisian population (more than 175,000 recruits).

BACKGROUND: In front of the considerable impact of the viral hepatitis C, the prevention is more than ever a priority, based essentially on the screening. AIM: We realized an epidemiological study in a population of young recruits with the aim of considering prevalence of anti-hepatitis C Virus (anti-HCV) antibodies, describing its epidemiological evolution and establishing a cartography of the viral hepatitis C in Tunisia. METHODS: Epidemiological retrospective study of prevalence was realized from the data of the screening of anti-HCV antibodies from 2003 till 2012 of all the young recruits suggested to be incorporated for the national service or suggested to be recruited as career soldier. The study was exhaustive concerning 175 322 young and healthy male adults aged between 20 and 30 years old, originating from all parts of Tunisia. The screening was realized by third and fourth generation ELISA tests then validated by Immunoblot. RESULTS: The prevalence was 0.11% and the confirmed prevalence was 0.07%. The positive subjects were mainly between 20 and 25 years old (82.32%) and 91.05% were detected within the framework of their incorporations to the national service. The lowest prevalence was 0.07% in 2004, and the highest was 0.17% in 2011, without a significant tendency in the increase or in the decrease during the period of study (r = 0.857 ; p = 0.564). The screening of anti-VHC antibodies had an unequal geographical distribution according to a North-South decreasing gradient. The highest proportions were registered in the North-West (23.23%) and the District of Tunis (22.73%), contrary to the South-East which was weakly affected (3.54%). The governorates with the highest proportions were Tunis (19.19%), Bizerte (11.62%) and Jendouba (8.59%), the governorates of Monastir and Tataouine were weakly affected (0.51%). CONCLUSION: Prevalence of anti-HCV antibodies in the young and male Tunisian population was weak, stable without significant tendency in the increase or in the decrease from 2003 till 2012, characterized by an unequal geographical distribution according to a North-South decreasing gradient.

Pre-emptive treatment of hepatitis B infection by lamivudine in two Tunisian renal transplant recipients.

Infection with hepatitis B virus has a major implication for transplant recipients due to the risk of reactivation under immunosuppression, progression to chronic liver disease, development of liver cirrhosis and hepatocellular carcinoma. We report two cases of renal transplantation patients who were hepatitis B surface antigen positive before transplantation and were treated by Lamivudine.

[Predictive factors of response to peginterferon and ribavirin in Tunisians patients with chronic hepatitis C: report of 141 cases]. / Facteurs prédictifs de réponse à la bithérapie pégylée au cours de l'hépatite chronique c dans une population tunisienne: à propos de 141 cas.

BACKGROUND: The current treatment recommendation for chronic hepatitis c is the combination of peginterferon and ribavirin. AIMS: To report our experience in the treatment of chronic hepatitis c and determine the predictive factors of sustained virologic response. METHODS: Analysis of consecutive patients treated with peginterferon and ribavirine from 1st January 2000 and 31st December 2009. results: 141 patients with an average age of 50 years were included. 75 % of the patients were infected by a VHc of genotype 1. 22.6 % of the patients were cirrhotics. 7 % of the patients (n=10) had to stop the treatment because of severe side-effects. A reduction of the dose was indicated for 16 % of the patients (n=23). Among the 117 patients with the end of treatment virologic response, 24 patients (20.5%) relapse during the 6 months after the end of therapy. The sustained virologic response in intention to treat was 66 % (57.9 % in case of genotype 1-4 and 91 % in case of genotype 2-3). In multivariate analysis, 4 independent factors of sustained virologic response were identified: the male gender, a viral genotype not 1, a pre-therapeutic viral load ≤ 600 000 UI / ml and a rapid virologic response. CONCLUSION: Approximately two thirds of the patients with chronic hepatitis c achieved a sustained virologic response with peginterferon and ribavirin. Our results are comparable to those of the literature. They will credibly be improved by the introduction of the new antiviral agents.

[Outcomes of endoscopic gluing with cyanoacrylate glue of bleeding gastric varices]. / Résultats de l'obturation endoscopique des varices gastriques hémorragiques par colle biologique.

BACKGROUND: Gastric variceal bleeding is associated with significant morbidity and mortality. Its optimal treatment is not yet standardized and glue injection is the most often proposed treatment. The longterm results of this technique are still controversial. AIM: To assess the safety and efficacy of gastric variceal glue injection. METHODS: Consecutive patients that underwent glue injection for gastric variceal bleeding in our endoscopy unit, from January 2000 to August 2011, were assessed. RESULTS: Sixteen patients (9 men, 7 women) underwent cyanoacrylate glue injections for gastric variceal bleeding. The median follow-up period of 13 patients was 33 months (three were lost to follow-up). The average age was 60 years (3 - 80 years). All patients had stigmata of recent bleeding at endoscopy. Patients underwent an average of 2 gluing sessions (1-3 sessions). N-butyl-2-cyanoacrylate (Histoacryl ®) was the most often product used. No significant complications from cyanoacrylate injection were observed. No patient had a recurrent variceal bleeding. During the median follow-up period, two patients died. CONCLUSION: Our data suggest that cyanoacrylate injection therapy is safe and effective for the prevention of short- and long-term bleeding from gastric varices.

[Idiopathic portal hypertension associated with celiac disease: one case]. / Hypertension portale idiopathique associée à une maladie coeliaque: à propos d'un cas.

We describe for the first time a case of idiopathic portal hypertension (IPH) in a 31 year old patient with coeliac disease (CD). She had splenomegaly, pancytopenia and an unexplained portal hypertension in the absence of any histological abnormalities of the liver. The diagnosis of coeliac disease was based on histological and serological data. Treatment included a splenectomy and a splenorenal shunt.
