| 1 | Major osteoporotic fragility fractures: Risk factor updates and societal impact显示文摘Osteoporosis is a silent disease without any evidence of disease until a fracture occurs. Approximately 200 million people in the world are affected by osteoporosis and 8.9 million fractures occur each year worldwide. Fractures of the hip are a major public health burden, by means of both social cost and health condition of the elderly because these fractures are one of the main causes of morbidity, impairment, decreased quality of life and mortality in women and men. The aim of this review is to analyze the most important factors related to the enormous impact of osteoporotic fractures on population. Among the most common risk factors, low body mass index; history of fragility fracture, environmental risk, early menopause, smoking, lack of vitamin D, endocrine disorders(for example insulin-dependent diabetes mellitus), use of glucocorticoids, excessive alcohol intake, immobility and others represented the main clinical risk factors associated with augmented risk of fragility fracture. The increasing trend of osteoporosis is accompanied by an underutilization of the available preventive strategies and only a small number of patients at high fracture risk are recognized and successively referred for therapy. This report provides analytic evidences to assess the best practices in osteoporosis management and indications for the adoption of a correct healthcare strategy to significantly reduce the osteoporosis burden. Early diagnosis is the key to resize the impact of osteoporosis on healthcare system. In this context, attention must be focused on the identification of high fracture risk among osteoporotic patients. It is necessary to increase national awareness campaigns across countries in order to reduce the osteoporotic fractures incidence. | Paola Pisani Maria Daniela Renna Francesco Conversano Ernesto Casciaro Marco Di Paola Eugenio Quarta Maurizio Muratore Sergio Casciaro | 2016 | World Journal of Orthopedics2016，7，3： | 39 |
| 2 | Nerve growth factor involvement in liver cirrhosis and hepatocellular carcinoma显示文摘AIM: To define NGF (nerve growth factor) and its high- affinity receptor trkANGF presence and distribution in fibrotic liver and in HCC, and to verify if NGF might have a role in fibrosis and HCC. METHODS: Intracellular distribution of NGF and trkANGF were assessed by immunohistochemistry and immuno- electron microscopy in liver specimens from HCC, cirrhosis or both. ELISA was used to measure circulating NGF levels. RESULTS: NGF and trkANGF were highly expressed in HCC tissue, mainly localized in hepatocytes, endothelial and some Kupffer cells. In the cirrhotic part of the liver they were also markedly expressed in bile ducts epithelial and spindle-shaped cells. Surprisingly, in cirrhotic tissue from patients without HCC, both NGF and trkANGF were negative. NGF serum levels in cirrhotic and/or HCC patient were up to 25-fold higher than in controls. CONCLUSION: NGF was only detected in liver tissue with HCC present. Intracellular distribution suggests paracrine and autocrine mechanisms of action. Better definition of mechanisms may allow for therapeutic and diagnostic/prognostic use of NGF. | Guido Rasi Annalucia Serafino Lia Bellis Maria Teresa Lonardo Federica Andreola Manuela Zonfrillo Giovanni Vennarecci Pasquale Pierimarchi Paola Sinibaldi Vallebona Giuseppe Maria Ettorre Eugenio Santoro Claudio Puoti | 2007 | World Journal of Gastroenterology2007，13，37： | 13 |
| 3 | Differential diagnosis in inflammatory bowel disease colitis:State of the art and future perspectives显示文摘Distinction between Crohn's disease of the colonrectum and ulcerative colitis or inflammatory bowel disease(IBD) type unclassified can be of pivotal importance for a tailored clinical management,as each entity often involves specific therapeutic strategies and prognosis.Nonetheless,no gold standard is available and the uncertainty of diagnosis may frequently lead to misclassification or repeated examinations.Hence,we have performed a literature search to address the problem of differential diagnosis in IBD colitis,revised current and emerging diagnostic tools and refined disease classification strategies.Nowadays,the differential diagnosis is an untangled issue,and the proper diagnosis cannot be reached in up to 10% of patients presenting with IBD colitis.This topic is receiving emerging attention,as medical therapies,surgical approaches and leading prognostic outcomes require more and more disease-specific strategies in IBD patients.The optimization of standard diagnostic approaches based on clinical features,biomarkers,radiology,endoscopy and histopathology appears to provide only marginal benefits.Conversely,emerging diagnostic techniques in the field of gastrointestinal endoscopy,molecular pathology,genetics,epigenetics,metabolomics and proteomics have already shown promising results.Novel advanced endoscopic imaging techniques and biomarkers can shed new light for the differential diagnosis of IBD,better reflecting diverse disease behaviors based on specific pathogenic pathways. | Gian Eugenio Tontini Maurizio Vecchi Luca Pastorelli Markus F Neurath Helmut Neumann | 2015 | World Journal of Gastroenterology2015，21，1： | 13 |
| 4 | Contrast-enhanced ultrasound evaluation of hepatic microvascular changes in liver diseases显示文摘AIM:To assess if software assisted-contrast-enhanced ultrasonography (CEUS) provides reproducible perfusion parameters of hepatic parenchyma in patients affected by chronic liver disease. METHODS:Forty patients with chronic viral liver disease, with (n = 20) or without (n = 20) cirrhosis, and 10 healthy subjects underwent CEUS and video recordings of each examination were then analysed with Esaote's Qontrast software. CEUS dedicated software Qontrast was used to determine peak (the maximum signal intensity), time to peak (TTP), region of blood value (RBV) proportional to the area under the time-intensity curve, mean transit time (MTT) measured in seconds and region of blood flow (RBF). RESULTS:Qontrast-assisted CEUS parameters displayed high inter-observer reproducibility (k coefficients of 0.87 for MTT and 0.90 TTP). When the region of interest included a main hepatic vein, Qontrast-calculated TTP was significantly shorter in cirrhotic patients (vs non-cirrhotics and healthy subjects) (71.0 ± 11.3 s vs 82.4 ± 15.6 s, 86.3 ± 20.3 s, P < 0.05). MTTs in the patients with liver cirrhosis were significantly shorter than those of controls (111.9 ± 22.0 s vs 139.4 ± 39.8 s, P < 0.05), but there was no significant difference between the cirrhotic and non-cirrhotic groups (111.9 ± 22.0 s vs 110.3 ± 14.6 s). Peak enhancement in the patients with liver cirrhosis was also higher than that observed in controls (23.9 ± 5.9 vs 18.9 ± 7.1, P = 0.05). There were no significant intergroup differences in the RBVs and RBFs. CONCLUSION:Qontrast-assisted CEUS revealed reproducible differences in liver perfusion parameters during the development of hepatic fibrogenesis. | Francesco Ridolfi Teresa Abbattista Paolo Busilacchi Eugenio Brunelli | 2012 | World Journal of Gastroenterology2012，18，37： | 10 |
| 5 | Multiple cells of origin in cholangiocarcinoma underlie biological,epidemiological and clinical heterogeneity显示文摘Recent histological and molecular characterization of cholangiocarcinoma(CCA) highlights the heterogeneity of this cancer that may emerge at different sites of the biliary tree and with different macroscopic or morphological features.Furthermore,different stem cell niches have been recently described in the liver and biliarytree,suggesting this as the basis of the heterogeneity of intrahepatic(IH)-and extrahepatic(EH)-CCAs,which are two largely different tumors from both biological and epidemiological points of view.The complexity of the organization of the liver stem cell compartments could underlie the CCA clinical-pathological heterogeneity and the criticisms in classifying primitive liver tumors.These recent advances highlight a possible new classification of CCAs based on cells of origin and this responds to the need of generating homogenous diagnostic,prognostic and,hopefully,therapeutic categories of IH-and EH-CCAs. | Vincenzo Cardinale Guido Carpino Lola Reid Eugenio Gaudio Domenico Alvaro | 2012 | World Journal of Gastrointestinal Oncology2012，4，5： | 10 |

| 8 | Subtotal gastrectomy for gastric cancer显示文摘Although a steady decline in the incidence and mortality rates of gastric carcinoma has been observed in the last century worldwide,the absolute number of new cases/year is increasing because of the aging of the population. So far,surgical resection with curative intent has been the only treatment providing hope for cure;therefore,gastric cancer surgery has become a specialized field in digestive surgery. Gastrectomy with lymph node(LN) dissection for cancer patients remains a challenging procedure which requires skilled,well-trained surgeons who are very familiar with the fast-evolving oncological principles of gastric cancer surgery. As a matter of fact,the extent of gastric resection and LN dissection depends on the size of the disease and gastric cancer surgery has become a patient and 'diseasetailored' surgery,ranging from endoscopic resection to laparoscopic assisted gastrectomy and conventional extended multivisceral resections. LN metastases are the most important prognostic factor in patients that undergo curative resection. LN dissection remains the most challenging part of the operation due to the location of LN stations around major retroperitoneal vessels and adjacent organs,which are not routinely included in the resected specimen and need to be preserved in order to avoid dangerous intra-and postoperative complications.Hence,the surgeon is the most important non-TMN prognostic factor in gastric cancer.Subtotal gastrectomy is the treatment of choice for middle and distal-third gastric cancer as it provides similar survival rates and better functional outcome compared to total gastrectomy,especially in early-stage disease with favorable prognosis.Nonetheless,the resection range for middle-third gastric cancer cases and the extent of LN dissection at early stages remains controversial.Due to the necessity of a more extended procedure at advanced stages and the trend for more conservative treatments in early gastric cancer,the indication for conventional subtotal gastrectomy depends on multiple variables.This review aims to clarify and define the actual landmarks of this procedure and the role it plays compared to the whole range of new and old treatment methods. | Roberto Santoro Giuseppe M Ettorre Eugenio Santoro | 2014 | World Journal of Gastroenterology2014，20，38： | 9 |
| 9 | Complete fuzzy scheduling and fuzzy earned value management in construction projects显示文摘This paper aims to present a comprehensive proposal for project scheduling and control by applying fuzzy earned value.It goes a step further than the existing literature:in the formulation of the fuzzy earned value we consider not only its duration,but also cost and production,and alternatives in the scheduling between the earliest and latest times.The mathematical model is implemented in a prototypical construction project with all the estimated values taken as fuzzy numbers.Our findings suggest that different possible schedules and the fuzzy arithmetic provide more objective results in uncertain environments than the traditional methodology.The proposed model allows for controlling the vagueness of the environment through the adjustment of the α-cut,adapting it to the specific circumstances of the project. | José Luís PONZ-TIENDA Eugenio PELLICER Víctor YEPES | 2012 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2012，13，1： | 9 |
| 10 | Agriculture in Hilly and Mountainous Landscapes: Threats, Monitoring and Sustainable Management显示文摘Agricultural landscapes cultivated in hilly and mountainous areas,often with terracing practice,could represent for some regions historical heritages and cultural ecosystem services.For this reason,they deserve to be protected.The complex morphology that characterises them,however,makes these areas intrinsically susceptible to hydrogeological instability,such as soil loss due to surface erosion or more severe mass movements.We can identify three major critical factors for such landscapes.The first is related to the socio-economic evolution of contemporary civilization,that increased the land abandonment of several rural regions,leading therefore to a lack of maintenance.A second element is the unsustainable agricultural practices,such as excessive heavymechanization that cause soil compaction thus accelerating degradation.Finally,the climate change forcing,with the increasing of the extreme rainfall.In this complex framework,it is necessary to find innovative solutions for the mitigation of hydrogeological risk and to respond in a well-prepared way to the possible future critical scenarios.Therefore,the use of sustainable agricultural practices,which allow the production of quality agricultural products in perfect harmony with the surrounding environment,becomes crucial.Suitable solutions must respond to the criterion of multidisciplinary,where the various stakeholders collaborate by offering their specific knowledge in a shared intention of problem-solving.The discipline of geography may become a valuable asset in this framework.In particular,thanks to the recent technological advances in the topographic survey(e.g.innovative remote sensing techniques such as drones and airborne laser scanning),it is possible to exploit digital terrain analysis to synthesize key information for decision-makers,in order to plan sustainable interventions.Moreover,thanks to the high-resolution and accuracy offered by digital topography and the advanced morphometric algorithms,it is possible to tackle the problem of hydrogeological risk from a unique and privileged perspective:that of prevention. | Paolo Tarolli Eugenio Straffelini | 2020 | Geography and Sustainability2020，1，1： | 8 |
| 11 | Neurological disorders and inflammatory bowel diseases显示文摘Extraintestinal manifestations occur in about one-third of patients living with inflammatory bowel disease(IBD) and may precede the onset of gastrointestinal symptoms by many years. Neurologic disorders associated with IBD are not frequent, being reported in 3% of patients, but they often represent an important cause of morbidity and a relevant diagnostic issue. In addition, the increasing use of immunosuppressant and biological therapies for IBD may also play a pivotal role in the development of neurological disorders of different type and pathogenesis. Hence, we provide a complete and profound review of the main features of neurological complications associated with IBD, with particular reference to those related to drugs and with a specific focus on their clinical presentation and possible pathophysiological mechanisms. | Giovanni Casella Gian Eugenio Tontini Gabrio Bassotti Luca Pastorelli Vincenzo Villanacci Luisa Spina Vittorio Baldini Maurizio Vecchi | 2014 | World Journal of Gastroenterology2014，20，27： | 7 |

| 13 | Imaging of the small bowel in Crohn's disease: A review of old and new techniques显示文摘The investigation of small bowel morphology is often mandatory in many patients with Crohn's disease. Traditional radiological techniques (small bowel enteroclysis and small bowel follow-through) have long been the only suitable methods for this purpose. In recent years, several alternative imaging techniques have been proposed. To review the most recent advances in imaging studies of the small bowel, with particular reference to their possible application in Crohn's disease, we conducted a complete review of the most important studies in which traditional and newer imaging methods were performed and compared in patients with Crohn's disease. Several radiological and endoscopic techniques are now available for the study of the small bowel; each of them is characterized by a distinct profile of favourable and unfavourable features. In some cases, they may also be used as complementary rather than alternative techniques. In everyday practice, the choice of the technique to be used stands upon its availability and a careful evaluation of diagnostic accuracy, clinical usefulness, safety and cost. The recent development ofinnovative imaging techniques has opened a new and exciting area in the exploration of the small bowel in Crohn's disease patients. | Simone Saibeni Emanuele Rondonotti Andrea Iozzelli Luisa Spina Gian Eugenio Tontini Flaminia Cavallaro Camilla Ciscato Roberto de Franchis Francesco Sardanelli Maurizio Vecchi | 2007 | World Journal of Gastroenterology2007，13，24： | 6 |
| 14 | Pulmonary vein stenosis:Etiology,diagnosis and management显示文摘Pulmonary vein stenosis(PVS) is rare condition characterized by a challenging diagnosis and unfavorable prognosis at advance stages. At present, injury from radiofrequency ablation for atrial fibrillation has become the main cause of the disease. PVS is characterized by a progressive lumen size reduction of one or more pulmonary veins that, when hemodynamically significant, may raise lobar capillary pressure leading to signs and symptoms such as shortness of breath, cough, and hemoptysis. Image techniques(transesophageal echocardiography, computed tomography, magnetic resonance and perfusion imaging) are essential to reach a final diagnosis and decide an appropriate therapy. In this regard, series from referral centers have shown that surgical and transcatheter interventions may improve prognosis. The purpose of this article is to review the etiology, assessment and management of PVS. | Pablo Pazos-López Cristina García-Rodríguez Alba Guitián-González Emilio Paredes-Galán María ángel De La Guarda álvarez-Moure Marta Rodríguez-álvarez José Antonio Baz-Alonso Elvis Teijeira-Fernández Francisco Eugenio Calvo-Iglesias Andrés íniguez-Romo | 2016 | World Journal of Cardiology2016，8，1： | 6 |
| 15 | Common features between neoplastic and preneoplastic lesions of the biliary tract and the pancreas显示文摘the bile duct system and pancreas show many similarities due to their anatomical proximity and common embryological origin.Consequently,preneoplastic and neoplastic lesions of the bile duct and pancreas share analogies in terms of molecular,histological and pathophysiological features.Intraepithelial neoplasms are reported in biliary tract,as biliary intraepithelial neoplasm(BilIN),and in pancreas,as pancreatic intraepithelial neoplasm(PanIN).Both can evolve to invasive carcinomas,respectively cholangiocarcinoma(CCA)and pancreatic ductal adenocarcinoma(PDAC).Intraductal papillary neoplasms arise in biliary tract and pancreas.Intraductal papillary neoplasm of the biliary tract(IPNB)share common histologic and phenotypic features such as pancreatobiliary,gastric,intestinal and oncocytic types,and biological behavior with the pancreatic counterpart,the intraductal papillary mucinous neoplasm of the pancreas(IPMN).All these neoplastic lesions exhibit similar immunohistochemical phenotypes,suggesting a common carcinogenic process.Indeed,CCA and PDAC display similar clinic-pathological features as growth pattern,poor response to conventional chemotherapy and radiotherapy and,as a consequence,an unfavorable prognosis.The objective of this review is to discuss similarities and differences between the neoplastic lesions of the pancreas and biliary tract with potential implications on a common origin from similar stem/progenitor cells. | Piera Zaccari Vincenzo Cardinale Carola Severi Federica Pedica Guido Carpino Eugenio Gaudio Claudio Doglioni Maria Chiara Petrone Domenico Alvaro Paolo Giorgio Arcidiacono Gabriele Capurso | 2019 | World Journal of Gastroenterology2019，25，31： | 6 |
| 16 | Heavy cigarette smoking and alcohol consumption are associated with impaired sperm parameters in primary infertile men显示文摘We assessed the concomitant impact of cigarette smoking and alcohol con sumption in men presenting for primary couple's infertility.Data from 189 in fertile men were an a lyzed.Semen analysis,serum hormones,and sperm DNA fragmentation(SDF)were obtained.Smoking status was categorized as follows:current nonsmoker(-S),moderate smoker(+MS),and heavy smoker(+HS).Alcohol consumption was categorized as follows:abstainer(-D),moderate drinker(+MD),and heavy drinker(+HD).Descriptive statistics and logistic regression models were applied.Among all the participants,132(69.8%),30(15.9%),and 27(14.3%)patients were-S,+MS,and+HS,respectively.In addition,67(35.4%),77(40.7%)and 45(23.8%)men were-D,+MD and+HD,respectively.Regarding concomitant habits,52(27.5%)patients were nonsmokers and abstainers(-S/-D:Group 1),91(48.1%)had at least one recreational habit(-S/+D or+S/-D:Group 2),and 46(24.3%)were both smokers and drinkers(+S/+D:Group 3).Sperm concentration and progressive motility were lower in+HS and+HD,compared with-S and-D(all P<0.05),respectively.Similarly,both parameters were significantly lower in Group 3 than Groups 1 and 2(all P<0.05).SDF values were higher in Group 3 than Groups 1 and 2(both P<0.05).In multivariate analysis,follicle-stimulating hormone(FSH)levels and concomitant+S/+D status were independent predictors of impaired sperm concentration and progressive motility(all P<0.05).Heavy smoking and heavy drinking were associated with worse seminal parameters than moderate smoking/drinking and nonsmoking/abstaining.When concomitant,+S/+D status has an even greater detrimental effect on semen parameters. | Luca Boeri Paolo Capogrosso Eugenio Ventimiglia Filippo Pederzoli Walter Cazzaniga Francesco Chierigo Federico Deho Emanuele Montanari Francesco Montorsi Andrea Salonia | 2019 | Asian Journal of Andrology2019，21，5： | 6 |
| 17 | Tectonically asymmetric Earth:From net rotation to polarized westward drift of the lithosphere显示文摘The possibility of a net rotation of the lithosphere with respect to the mantle is generally overlooked since it depends on the adopted mantle reference frames,which are arbitrary.We review the geological and geophysical signatures of plate boundaries,and show that they are markedly asymmetric worldwide.Then we compare available reference frames of plate motions relative to the mantle and discuss which is at best able to fit global tectonic data.Different assumptions about the depths of hotspot sources(below or within the asthenosphere,which decouples the lithosphere from the deep mantle) predict different rates of net rotation of the lithosphere relative to the mantle.The widely used no-net-rotation(NNR) reference frame,and low(<0.2°-0.4° /Ma) net rotation rates(deep hotspots source) predict an average net rotation in which some plates move eastward relative to the mantle(e.g.,Nazca).With fast(>1° /Ma) net rotation(shallow hotspots source),all plates,albeit at different velocity,move westerly along a curved trajectory,with a tectonic equator tilted about 30° relative to the geographic equator.This is consistent with the observed global tectonic asymmetries. | Carlo Doglioni Eugenio Carminati Mattia Crespi Marco Cuffaro Mattia Penati Federica Riguzzi | 2015 | Geoscience Frontiers2015，6，3： | 5 |
| 18 | Treatment for isolated loco-regional recurrence of gastric adenocarcinoma: Does surgery play a role?显示文摘AIM: To evaluate the role of surgical treatment for isolated loco-regional recurrences of operated gastric adenocarcinoma. METHODS: Among the 837 patients operated for gastric adenocarcinoma between December 1979 and April 2004, 713 (85%) underwent resection with curative intent. A retrospective review of a prospectively collected gastric cancer database was carried out. Overall recurrence rate was 44% (315 cases), with 75% occurring within the first 2 years from the operation. Isolated L-R recurrences were observed in 38 (12%) patients. Symptomatic lesions were observed in 27 (71%). RESULTS: Six (16%) patients were macroscopically resected with curative intent. The recurrence was located in the gastric stump after a STG in three patients, in the esophagojejunal anastomosis after a TG in two patients and in the gastric bed after a TG in one patient. Surgical procedures consisted of three secondary TG, two esophagojejunal resection and one excision of an extraluminal recurrence. Postoperative complications occurred in two patients (33%), including one anastomotic leakage and one hemorrhage. The latter patient died of sepsis 35 d after the surgery (mortality rate 17%). All patients died of recurrent gastric cancer: 2 within 1 year from surgery (8 and 11 mo, respectively), 2 after 16 and 17 mo respectively and 1 after 28 mo from the second operation. CONCLUSION: Surgery plays a very limited role in the treatment for isolated loco-regional recurrence of gastric adenocarcinoma. | Fabio Carboni Pasquale Lepiane Roberto Santoro Riccardo Lorusso Pietro Mancini Massimo Carlini Eugenio Santoro | 2005 | World Journal of Gastroenterology2005，11，44： | 5 |
| 19 | 屏蔽并且通过 X 光检查和超声的骨质疏松症的早诊断基于技术显示文摘 Effective prevention and management of osteoporosis would require suitable methods for population screenings and early diagnosis. Current clinicallyavailable diagnostic methods are mainly based on the use of either X-rays or ultrasound(US). All X-ray based methods provide a measure of bone mineral density(BMD), but it has been demonstrated that other structural aspects of the bone are important in determining fracture risk, such as mechanical features and elastic properties, which cannot be assessed using densitometric techniques. Among the most commonly used techniques, dual X-ray absorptiometry(DXA) is considered the current 'gold standard' for osteoporosis diagnosis and fracture risk prediction. Unfortunately, as other X-ray based techniques, DXA has specific limitations(e.g., use of ionizing radiation, large size of the equipment, high costs, limited availability) that hinder its application for population screenings and primary care diagnosis. This has resulted in an increasing interest in developing reliable pre-screening tools for osteoporosis such as quantitative ultrasound(QUS) scanners, which do not involve ionizing radiation exposure and represent a cheaper solution exploiting portable and widely available devices. Furthermore, the usefulness of QUS techniques in fracture risk prediction has been proven and, with the last developments, they are also becoming a more and more reliable approach for assessing bone quality. However, the US assessment of osteoporosis is currently used only as a pre-screening tool, requiring a subsequent diagnosis confirmation by means of a DXA evaluation. Here we illustrate the state of art in the early diagnosis of this 'silent disease' and show up recent advances for its prevention and improved management through early diagnosis. | Paola Pisani Maria Daniela Renna Francesco Conversano Ernesto Casciaro Maurizio Muratore Eugenio Quarta Marco Di Paola Sergio Casciaro | 2013 | World Journal of Radiology2013，5，11： | 4 |
| 20 | Efficacy and tolerability of high and low-volume bowel preparation compared:A real-life single-blinded large-population study显示文摘BACKGROUND Low-volume preparations for colonoscopy have shown similar efficacy compared to high-volume ones in randomized controlled trials(RCT).However,most RCTs do not provide data about clinical outcomes including lesions detection rate.Moreover,real-life comparisons are lacking.AIM To compare efficacy(both in terms of adequate bowel preparation and detection of colorectal lesions)and tolerability of a high-volume(HV:4 L polyethylene glycol,PEG)and a low-volume(LV:2 L PEG plus bisacodyl)bowel preparation in a real-life setting.METHODS Consecutive outpatients referred for colonoscopy were prospectively enrolled between 1 December 2014 and 31 December 2016.Patients could choose either LV or HV preparation,with a day-before schedule for morning colonoscopies and a split-dose for afternoon procedures.Adequate bowel preparation according to Boston Bowel Preparation Scale(BBPS),clinical outcomes including polyp detection rate(PDR),adenoma detection rate(ADR),advanced adenoma detection rate(AADR),sessile/serrated lesion detection rate(SDR)and cancer detection rate and self-reported tolerability of HV and LV were blindly assessed.RESULTS Total 2040 patients were enrolled and 1815(mean age 60.6 years,50.2%men)finally included.LV was chosen by 52%of patients(50.8%of men,54.9%of women).Split-dose schedule was more common with HV(44.7%vs 38.2%,P=0.005).High-definition scopes were used in 33.4%of patients,without difference in the two groups(P=0.605).HV and LV preparations showed similar adequate bowel preparation rates(89.2%vs 86.6%,P=0.098),also considering the two different schedules(HV split-dose 93.8%vs LV split-dose 93.6%,P=1;HV daybefore 85.5%vs LV day-before 82.3%,P=0.182).Mean global BBPS score was higher for HV preparations(7.1±1.7 vs 6.8±1.6,P<0.001).After adjustment for sex,age and indications for colonoscopy,HV preparation resulted higher in PDR[Odds ratio(OR)1.32,95%CI:1.07-1.63,P=0.011]and ADR(OR 1.29,95%CI 1.02–1.63,P=0.038)and comparable to LV in AADR(OR 1.51,95%CI 0.97-2.35,P=0.069),SDR and cancer detection rate.The use of standard-definition colonoscopes was associated to lower PDR(adjusted OR 1.59,95%CI:1.22-2.08,P<0.001),ADR(adjusted OR 1.71,95%CI:1.26–2.30,P<0.001)and AADR(adjusted OR 1.97,95%CI:1.09-3.56,P=0.025)in patients receiving LV preparation.Mean Visual Analogue Scale tolerability scored equally(7,P=0.627)but a≥75%dose intake was more frequent with LV(94.6%vs 92.1%,P=0.003).CONCLUSION In a real-life setting,PEG-based low-volume preparation with bisacodyl showed similar efficacy and tolerability compared to standard HV preparation.However,with higher PDR and ADR,HV should still be considered as the reference standard for clinical trials and the preferred option in screening colonoscopy,especially when colonoscopy is performed with standard resolution imaging. | Vincenzo Occhipinti Paola Soriani Francesco Bagolini Valentina Milani Emanuele Rondonotti Maria Laura Annunziata Flaminia Cavallaro Sara Vavassori Maurizio Vecchi Luca Pastorelli Gian Eugenio Tontini | 2021 | World Journal of Gastrointestinal Endoscopy2021，13，12： | 4 |
