Background: A new noninvasive medical device based on ultrasound elastography such as the Shear Wave Elastography (SWE) was designed in order to measure the liver hardness. The purpose of this work was to evaluate the correlation of the results of the liver elasticity measurements obtained by Fibroscan® (FS) and SWE for patients with chronic liver diseases. Methods: Between January and October 2017, the patients who were followed during this period of time underwent noninvasive assessments of liver fibrosis by SWE in the intercostal spaces during abdominal ultrasound procedures and/or FS. The correlation between FS and SWE was estimated and tested at a 0.05 significance level. Results: Four hundred and seventy-six patients were included in this study. The main etiologies of chronic liver disease were non alcoholic fatty disease (NAFLD), chronic viral hepatitis B (HBV) and chronic viral hepatitis C (HCV). All patients underwent a SWE and 167 among them underwent a FS procedure. The patients who were followed revealed a median FS measurement of 5.80 kpa (Q25 = 4.90 kPa; Q75 = 8 kPa) and a median SWE measurement of 7.00 kPa (Q25 = 6.10 kPa; Q75 = 8.10 kPa). We could observe a significant correlation between the FS and SWE measurements (0.49; P = .001) in the total cohort. The average absolute difference between the measurements of these 2 methods was of 2.54 kPa (sd = 3.39). There was no significant correlation for patients with NAFLD no matter whether they presented with signs of suspected non alcoholic steatohepatitis (NASH) or not ( R = 0.20; P = .108). All patients intending to perform the examination were able to undergo the SWE, allowing 33.3% of the patients who failed the FS to have a noninvasive evaluation of their fibrosis. Conclusion: The SWE technique proved to be as efficient as the FS one for the evaluation of the liver fibrosis in real life situation.
ERCP in 0,48% of patients with gallstone disease, the median age was 55.5 (46-69.5) without gender difference. 50% of our cases were diagnosed before surgery. Endoscopic therapeutic procedures included biliary decompression techniques using nasal bile drainage or plastic stents, balloon sweeping after selective catheterization of cystic duct and large balloon papillary dilation with double cannulation. The success rate of endoscopic management was 66,6%. Surgical treatment was performed at the same time as laparoscopic cholecystectomy in patients with lithiasic gall bladder. CONCLUSIONS: Mirizzi syndrome remains a fascinating and rare condition complicating gallstone disease with no uniform guidelines to date. Our study emphasizes the role of ERCP as a diagnostic and therapeutic procedure in the management of type I Mirizzi syndrome.
Objective To evaluate the prevalence of polyps and their treatments. Materials and Method This is a retrospective study conducted in our department over 20 years and 3 months between January 2000 and March 2021. All patients with colorectal polyps who underwent endoscopic resection were included. We evaluated the resection techniques and the management of complications. Results The total number of patients was 273, with a mean age of 57.26 ± 14.058 (18–90) and a M/W sex ratio of 2. The prevalence was 3.35% and the mean number of polyps was 1.33 ± 0.69. The most frequent symptoms were rectal bleeding (23.5%) and constipation (12.1%). The median size was 6 mm (4–12 mm). The left colonic location was the most frequent site (43%). All polyps were classified according to the Paris classification, with a predominance of sessile polyps in 45.75%, followed by pedunculated polyps, representing 42.4%. Endoscopic resection was performed either by biopsy forceps, polypectomy, or mucosectomy in 30.2%, 27.4%, and 25.4% of cases, respectively. Our study noted immediate bleeding in 1.5% of cases, and no perforations or late complications. All complications were treated endoscopically, and no patient required blood transfusion or surgical intervention. Conclusion Endoscopic resection of rectocolic polyps is the ideal treatment for these lesions. In our department, the prevalence was 3.35%, the most used resection techniques were forceps resection and polypectomy, and the complication rate was 1.5%.
Background: Klatskin's tumour is a cholangiocarcinoma that develops from the right or left bile ducts and the upper part of the main bile duct. They are usually diagnosed at an advanced, inoperable stage, and have an extremely poor prognosis. Biliary drainage is proposed in palliative situation and carries a high risk of infectious complications. The aim of our work is to report the results of endoscopic biliary drainage as well as the factors associated with its success or failure. Methods: This is a retrospective and analytical study of 75 patients, conducted between July 2009 and August 2021, including all patients admitted with Klatskin's tumour and for whom endoscopic drainage was indicated. Factors associated with the success or failure of endoscopic treatment were studied by logistic regression analysis. Results: The average age of our patients was 62.67 years with a male predominance of 68%. Cholangiocarcinoma was classified as bismuth IV in 50.6% of patients, bismuth IIIa in 30% of patients, bismuth IIIb in 13% of patients and bismuth II in 6% of patients. Sixteen percent of patients had liver metastases. Endoscopic drainage was successfully performed in 81.3% of patients by plastic prosthesis in 32% of cases, by a metal prosthesis in 45.2% and by nasobiliary drain in 4.1% . Forty-seven percent of patients had dilatation of the stenosis prior to prosthesis placement. Causes of stenting failure were primarily related to failure of papilla catheterisation, failure to pass the guidewire through the stenosis, or duodenal invasion by the tumour. In multivariate analysis and by adjusting the studied parameters, namely the age, gender, bismuth tumour type, presence of metastases and endoscopic dilatation of the stenosis, only the presence of metastases, endoscopic dilatation of the stenosis and the bismuth tumour classification affect the success rate. Indeed, endoscopic dilatation of the stenosis prior to stenting increases the success rate fourfold. Prosthesis increases the success rate by a factor of 4 [OR=4; p=0.01], whereas the presence of metastases decreases this rate by 65% [OR=0.35; p<0.001]. However, tumours classified as bismuth IV [OR=8; p<0.001] or bismuth IIIa [OR=5; p=0.004] were associated with a risk of endoscopic treatment failure. Conclusion: Our study suggests that the presence of metastatic hilar cholangiocarcinoma classified as bismuth IV or bismuth IIIa appear to be associated with failure of endoscopic biliary drainage, whereas endoscopic dilatation prior to prosthesis placement appears to be associated with success.
