Background and study aims
Endoscopic retrograde cholangiography (ERC) in patients with complex surgically-altered anatomy (SAA) is technically demanding and has limitations. Developments in EUS-guided procedures allow alternative approaches for patients with altered gastrointestinal anatomy and biliary lithiasis.
Patients and methods
Single-center, retrospective review of prospectively entered patients with SAA who underwent EUS-guided hepaticogastrostomy (HGS) followed by an interval antegrade endoscopic clearance of biliary lithiasis.
Results
9 patients with Roux-en-Y anatomy underwent HGS to allow clearance of biliary lithiasis after a mean of 2.5 procedures. Technical success was achieved in 100 % of patients utilizing subsequent antegrade endoscopic techniques after HGS including: balloon sweep (9), transpapillary balloon dilation (8), cholangioscopy with electrohydraulic lithotripsy (4), and mechanical lithotripsy (1). HGS stents were removed in all patients. 1 adverse event (cholangitis) occurred after cholangioscopy and prolonged intraductal electrohydraulic lithotripsy.
Conclusion
EUS-guided antegrade therapy for the management of biliary lithiasis in patients with altered gastrointestinal anatomy appears efficacious with a low risk of adverse events. These preliminary results suggest this approach should be considered at centers with available expertise.
BackgroundMigraine is a common disorder in general population. Presence of white matter hyperintensities (WMHs) in brain MRI of migraine patients was not studied clearly. Detection of the prevalence of white matter hyperintensities in migraine patients determines its correlation with migraine severity, type and duration.MethodsCross sectional analytic study was conducted on migraine patients attending neurology clinic Suez Canal University Hospital. Sixty-five patients with migraine aged from 18 to 50 years were included. We excluded smokers and patients with hypertension, cardiac disease, diabetes mellitus, endocrine dysfunction, oncological and hematological diseases, infectious diseases, demyelinating disorders, and Alzheimer disease. Brain MRI and laboratory investigation was done for all patients.ResultsWhite matter hyperintensities were significant more frequent in migraine with aura than those without aura. According to MIGSEV scale, white matter hyperintensities were highly significantly more frequent in grade III severity than grades II and I. The number of white matter hyperintensities increases significantly with increase intensity of pain during attack. The number of white matter hyperintensities increases significantly with increase intensity of nausea, disability, tolerability during attack and age. Resistance to treatment also shows statistically significant difference in increase number of WMHs.ConclusionsWhite matter hyperintensities are present in 43.1% of migraine patients. Age, presence of aura, nausea, disability during attack, resistance to treatment, and severity of headache and duration of migraine are considered a risk factor for development of white matter hyperintensities.
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.
