| 1 | Sonography of the small intestine显示文摘In the last two decades, there has been substantial development in the diagnostic possibilities for examining the small intestine. Compared with computerized tomography, magnetic resonance imaging, capsule endoscopy and double-balloon endoscopy, ultrasonography has the advantage of being cheap, portable, flexible and user-and patient-friendly, while at the same time providing the clinician with image data of high temporal and spatial resolution. The method has limitations with penetration in obesity and with intestinal air impairing image quality. The flexibility ultrasonography offers the examiner also implies that a systematic approach during scanning is needed. This paper reviews the basic scanning techniques and new modalities such as contrast-enhanced ultrasound, elastography, strain rate imaging, hydrosonography, allergosonography, endoscopic sonography and nutritional imaging, and the literature on disease-specific findings in the small intestine. Some of these methods have shown clinical benefit, while others are under research and development to establish their role in the diagnostic repertoire. However, along with improved overall image quality of new ultrasound scanners, these methodshave enabled more anatomical and physiological changes in the small intestine to be observed. Accordingly, ultrasound of the small intestine is an attractive clinical tool to study patients with a range of diseases. | Kim Nylund Svein Фdegaard Trygve Hausken Geir Folvik Gülen Arslan Lied Ivan Viola Helwig Hauser Odd-Helge Gilja | 2009 | World Journal of Gastroenterology2009,15,11: | 9 |
| 2 | Acute necrotizing pancreatitis as fi rst manifestation of primary hyperparathyroidism显示文摘We report the case of a female patient with severe acute necrotizing pancreatitis associated with hypercalcemia as first manifestation of primary hyperparathyroidism caused by a benign parathyroid adenoma.Initially the acute pancreatitis was treated conservatively.The patient subsequently underwent surgical resection of the parathyroid adenoma and surgical clearance of a large infected pancreatic pseudocyst.Although the association of parathyroid adenoma-induced hypercalcemia and acute pancreatitis is a known medical entity,it is very uncommon.The pathophysiology of hypercalcemia-induced acute pancreatitis is therefore not well known,although some mechanisms have been proposed.It is important to treat the provoking factor.Therefore,the cause of hypercalcemia should be identif ied early.Surgical resection of the parathyroid adenoma is the ultimate therapy. | Jeroen I Lenz Jimmy M Jacobs Bart Op de Beeck Ivan A Huyghe Paul A Pelckmans Tom G Moreels | 2010 | World Journal of Gastroenterology2010,16,23: | 9 |
| 3 | Contribution of functional KIR3DL1 to ankylosing spondylitis显示文摘Increasing evidence points to a role for killer immunoglobulin-like receptors(KIRs)in the development of autoimmune diseases.In particular,a positive association of KIR3DS1(activating receptor)and a negative association of KIR3DL1(inhibitory receptor)alleles with ankylosing spondylitis(AS)have been reported by several groups.However,none of the studies analyzed these associations in the context of functionality of polymorphic KIR3DL1.To better understand how the KIR3DL1/3DS1 genes determine susceptibility to AS,we analyzed the frequencies of alleles and genotypes encoding functional(KIR3DL1*F)and non-functional(KIR3DL1*004)receptors.We genotyped 83 AS patients and 107 human leukocyte antigen(HLA)-B27-positive healthy controls from the Russian Caucasian population using a two-stage sequence-specific primer PCR,which distinguishes KIR3DS1,KIR3DL1*F and KIR3DL1*004 alleles.For the patients carrying two functional KIR3DL1 alleles,those alleles were additionally genotyped to identify KIR3DL1*005 and KIR3DL1*007 alleles,which are functional but are expressed at low levels.KIR3DL1 was negatively associated with AS at the expense of KIR3DL1*F but not of KIR3DL1*004.This finding indicates that the inhibitory KIR3DL1 receptor protects against the development of AS and is not simply a passive counterpart of the segregating KIR3DS1 allele encoding the activating receptor.However,analysis of genotype frequencies indicates that the presence of KIR3DS1 is a more important factor for AS susceptibility than the absence of KIR3DL1*F.The activation of either natural killer(NK)or T cells via the KIR3DS1 receptor can be one of the critical events in AS development,while the presence of the functional KIR3DL1 receptor has a protective effect.Nevertheless,even individuals with a genotype that carried two inhibitory KIR3DL1 alleles expressed at high levels could develop AS. | Ivan V Zvyagin Ilgar Z Mamedov Olga V Britanova Dmitriy B Staroverov Evgeni L Nasonov Anna G Bochkova Anna V Chkalina Alexei A Kotlobay Dmitriy O Korostin Denis V Rebrikov Sergey Lukyanov Yuri B Lebedev Dmitriy M Chudakov | 2010 | Cellular & Molecular Immunology2010,7,6: | 5 |

| 6 | How to treat intestinal obstruction due to malignant recurrence after Whipple's resection for pancreatic head cancer: description of 2 new endoscopic techniques显示文摘The prognosis of pancreatic cancer remains poor,even after initial surgical therapy. Local recurrence after Whipple's pancreatico-duodenectomy may lead to intestinal obstruction at the level of the afferent limb or the alimentary limb. Endoscopic insertion of a selfexpandable metal stent(SEMS) into the intestinal malignant stricture is the preferred method of choice for palliation. We describe two new endoscopic techniques to treat a malignant intestinal obstruction with the insertion of a SEMS into the afferent limb and the alimentary limb. A case of malignant gastric outlet obstruction after a Whipple's resection was treated by the creation of an endoscopic gastrojejunostomy by the insertion of a lumen apposing Hot Axios stent in between the stomach and the alimentary limb under fluoroscopic and endoscopic ultrasound control. Biliary obstruction and jaundice caused by a malignant stricture of the afferent limb after a Roux-en-Y Whipple's resection was treated by the insertion of a SEMS by means of the single-balloon overtube-assisted technique under fluoroscopic control. Feasibility and advantages of both techniques are discussed. | Christina Mouradides Alaa Taha Ivan Borbath Pierre H Deprez Tom G Moreels | 2017 | World Journal of Gastroenterology2017,23,33: | 3 |
| 7 | Advanced imaging and visualization in gastrointestinal disorders显示文摘Advanced medical imaging and visualization has a strong impact on research and clinical decision making in gastroenterology. The aim of this paper is to show how imaging and visualization can disclose structural and functional abnormalities of the gastrointestinal (GI) tract. Imaging methods such as ultrasonography, magnetic resonance imaging (MRI), endoscopy, endosonography, and elastography will be outlined and visualization with Virtual Reality and haptic methods. Ultrasonography is a versatile method that can be used to evaluate antral contractility, gastric emptying, transpyloric flow, gastric configuration, intragastric distribution of meals, gastric accommodation and strain measurement of the gastric wall. Advanced methods for endoscopic ultrasound, three-dimensional (3D) ultrasound, and tissue Doppler (Strain Rate Imaging) provide detailed information of the GI tract. Food hypersensitivity reactions including gastrointestinal reactions due to food allergy can be visualized by ultrasonography and MRI. Development of multi-parametric and multi-modal imaging may increase diagnostic benefits and facilitate fusion of diagnostic and therapeutic imaging in the future. | Odd Helge Gilja Jan G Hatlebakk Svein φdegaard Arnold Berstad Ivan Viola Christopher Giertsen Trygve Hausken Hans Gregersen | 2007 | World Journal of Gastroenterology2007,13,9: | 2 |
| 8 | Osteosarcopenia in autoimmune cholestatic liver diseases:Causes,management,and challenges显示文摘Primary biliary cholangitis and primary sclerosing cholangitis(PSC)are the most common cholestatic liver diseases(CLD)in adults and are both characterized by an immune pathogenesis.While primary biliary cholangitis is a model autoimmune disease,with over 90%of patients presenting very specific autoantibodies against mitochondrial antigens,PSC is considered an immune mediated disease.Osteoporosis is the most common bone disease in CLD,resulting in frequent fractures and leading to significant morbidity.Further,sarcopenia is emerging as a frequent complication of chronic liver diseases with a significant prognostic impact and severe implications on the quality of life of patients.The mechanisms underlying osteoporosis and sarcopenia in CLD are still largely unknown and the association between these clinical conditions remains to be dissected.Although timely diagnosis,prevention,and management of osteosarcopenia are crucial to limit the consequences,there are no specific guidelines for management of osteoporosis and sarcopenia in patients with CLD.International guidelines recommend screening for bone disease at the time of diagnosis of CLD.However,the optimal monitoring strategies and treatments have not been defined yet and vary among centers.We herein aim to comprehensively outline the pathogenic mechanisms and clinical implications of osteosarcopenia in CLD,and to summarize expert recommendations for appropriate diagnostic and therapeutic approaches. | Nicola Pugliese Ivan Arcari Alessio Aghemo Andrea G Lania Ana Lleo Gherardo Mazziotti | 2022 | World Journal of Gastroenterology2022,28,14: | 2 |
