Background Splanchnic venous thrombosis (SVT) is a common vascular complication of acute pancreatitis (AP). We conducted this study to prospectively investigate the frequency, risk factors, and extent of SVT in patients with AP and to evaluate the role of thrombophilia in its causation.
Background:Splanchnic venous thrombosis (SVT) is a common vascular complication of acute pancreatitis (AP). We conducted this study to prospectively investigate the frequency, risk factors, and extent of SVT in patients with AP and to evaluate the role of thrombophilia in its causation.Methods:Patients with AP presenting between January 2015 and June 2016 were prospectively evaluated with contrast-enhanced computed tomography (CT) for the presence of SVT. These patients underwent a detailed analysis of coagulation parameters.Results:We evaluated 96 patients with AP (73 male, mean age 31.85±13.34 years), of whom 26 (27.1%) had SVT. Splenic vein, portal vein, and superior mesenteric vein involvement were seen in 22 (84.6%), 11 (42.3%), and 4 (15.3%) patients, respectively. Necrotizing pancreatitis, CT severity index (CTSI) >6 and modified CTSI >6 were significantly more frequent in patients with SVT than in those without (96.2% vs. 78.6%, 76.9% vs. 47.1%, and 92.3% vs. 67.1%, respectively). Proteins C and S, and antithrombin III deficiency were found in 23.8%, 33.3% and 31.0% of patients, respectively. Anti-β2-glycoprotein I and lupus anticoagulant were positive in 4.8% and 11.9% of patients, respectively. Factor V Leiden mutation analysis was positive in 6.1% of patients. Coagulation abnormality did not differ significantly between the patients with and without SVT.Conclusions:SVT is more common in patients with necrotizing pancreatitis, suggesting that local inflammation plays a major role in its causation. Thrombophilia is seen in one third of patients with AP but does not seem to increase the risk of SVT.
The peritoneum is involved in many diseases such as primary malignancy (mesothelioma), infectious disease (tuberculosis), and disseminated malignancy (peritoneal carcinomatosis). The peritoneal disease may manifest as ascites and/or peritoneal masses or nodules. Endoscopic ultrasound (EUS), due to its ability to provide high-resolution images, has revolutionized the imaging and diagnosis of pancreaticobiliary diseases among other gastrointestinal conditions. EUS can not only help in imaging of various lesions close to the gastrointestinal lumen but also aspirate/biopsy them. We conducted a systematic search to identify published literature on the value of EUS in detection and diagnosis of peritoneal disorders. This review aims to summarize the available literature on the use of EUS-guided paracentesis and fine-needle aspiration from peritoneal nodules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
