| 1 | Percutaneous endoscopic gastrostomy:Indications,technique,complications and management显示文摘Percutaneous endoscopic gastrostomy(PEG)is the preferred route of feeding and nutritional support in patients with a functional gastrointestinal system who require long-term enteral nutrition.Besides its wellknown advantages over parenteral nutrition,PEG offers superior access to the gastrointestinal system over surgical methods.Considering that nowadays PEG tube placement is one of the most common endoscopic procedures performed worldwide,knowing its indications and contraindications is of paramount importance in current medicine.PEG tubes are sometimes placed inappropriately in patients unable to tolerate adequate oral intake because of incorrect and unrealistic understanding of their indications and what they can accomplish.Broadly,the two main indications of PEG tube placement are enteral feeding and stomach decompression.On the other hand,distal enteral obstruction,severe uncorrectable coagulopathy and hemodynamic instability constitute the main absolute contraindications for PEG tube placement in hospitalized patients.Although generally considered to be a safe procedure,there is the potential for both minor and major complications.Awareness of these potential complications,as well as understanding routine aftercare of the catheter,can improve the quality of care for patients with a PEG tube.These complications can generally be classified into three major categories:endoscopic technical difficulties,PEG procedure-related complications and late complications associated with PEG tube use and wound care.In this review we describe a variety of minor and major tube-related complications as well as strategies for their management and avoidance.Different methods of percutaneous PEG tube placement into the stomach have been described in the literature with the'pull'technique being the most common method.In the last section of this review,the reader is presented with a brief discussion of these procedures,techniques and related issues.Despite the mentioned PEG tube placement complications,this procedure has gained worldwide popularity as a safe enteral access for nutrition in patients with a functional gastrointestinal system. | Ata A Rahnemai-Azar Amir A Rahnemaiazar Rozhin Naghshizadian Amparo Kurtz Daniel T Farkas | 2014 | World Journal of Gastroenterology2014，20，24： | 38 |

| 4 | Minimally invasive surgery for gastric cancer: A comparison between robotic, laparoscopic and open surgery显示文摘AIM To investigate the role of minimally invasive surgery for gastric cancer and determine surgical, clinical, and oncological outcomes.METHODS This is a propensity score-matched case-control study, comparing three treatment arms: robotic gastrectomy(RG), laparoscopic gastrectomy(LG), open gastrectomy(OG). Data collection started after sharing a specific study protocol. Data were recorded through a tailored and protected web-based system. Primary outcomes: harvested lymph nodes, estimated blood loss, hospital stay, complications rate. Among the secondary outcomes, there are: operative time, R0 resections, POD of mobilization, POD of starting liquid diet and soft solid diet. The analysis includes the evaluation of type and grade of postoperative complications. Detailed information of anastomotic leakages is also provided.RESULTS The present analysis was carried out of 1026 gastrectomies. To guarantee homogenous distribution of cases, patients in the RG, LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper = 0.2. The successful matching resulted in a total sample of 604 patients(RG = 151; LG = 151; OG = 302). The three groups showed no differences in all baseline patients characteristics, type of surgery(P = 0.42) and stage of the disease(P = 0.16). Intraoperative blood loss was significantly lower in the LG(95.93 ± 119.22) and RG(117.91 ± 68.11) groups compared to the OG(127.26 ± 79.50, P = 0.002). The mean number of retrieved lymph nodes was similar between the RG(27.78 ± 11.45), LG(24.58 ± 13.56) and OG(25.82 ± 12.07) approach. A benefit in favor of the minimally invasive approaches was found in the length of hospital stay(P < 0.0001). A similar complications rate was found(P = 0.13). The leakage rate was not different(P = 0.78) between groups.CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery. The main highlighted benefit is a faster postoperative functional recovery. | Amilcare Parisi Daniel Reim Felice Borghi Ninh T Nguyen Feng Qi Andrea Coratti Fabio Cianchi Maurizio Cesari Francesca Bazzocchi Orhan Alimoglu Johan Gagnière Graziano Pernazza Simone D'Imporzano Yan-Bing Zhou Juan-Santiago Azagra Olivier Facy Steven T Brower Zhi-Wei Jiang Lu Zang Arda Isik Alessandro Gemini Stefano Trastulli Alexander Novotny Alessandra Marano Tong Liu Mario Annecchiarico Benedetta Badii Giacomo Arcuri Andrea Avanzolini Metin Leblebici Denis Pezet Shou-Gen Cao Martine Goergen Shu Zhang Giorgio Palazzini Vito D'Andrea Jacopo Desiderio | 2017 | World Journal of Gastroenterology2017，23，13： | 17 |

| 6 | The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment. | ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，2： | 11 |
| 7 | Surgical strategies in the therapy of non-small cell lung cancer显示文摘Lung cancer represents the leading cause of cancer mortality worldwide. Despite improvements in preoperative staging, surgical techniques, neoadjuvant/adjuvant options and postoperative care, there are still major difficulties in significantly improving survival, especially in locally advanced non-small cell lung cancer(NSCLC). To date, surgical resection is the primary mode of treatment for stage?Ⅰ?and Ⅱ NSCLC and has become an important component of the multimodality therapy of even more advanced disease with a curative intention. In fact, in NSCLC patients with solitary distant metastases, surgical interventions have been discussed in the last years. Accordingly, this review displays the recent surgical strategies implemented in the therapy of NSCLC patients. | Feras Al-Shahrabani Daniel Vallbhmer Sebastian Angenendt Wolfram T Knoefel | 2014 | World Journal of Clinical Oncology2014，5，4： | 10 |
| 8 | Update on the natural history of intracranial atherosclerotic disease: A critical review显示文摘Intracranial atherosclerotic disease (ICAD) contributes to a significant number of ischemic strokes. There is debate in the recent literature concerning the impact of the location of stenosis in ICAD on outcome. Some reports have suggested that disease processes and outcomes vary by vessel location, potentially altering the natural history and indications for intervention. Here we have performed a comprehensive, critical review of the natural history of ICAD by vessel in an attempt to assess the differences in disease specific to each of the vascular territories. Our assessment concludes that only minor differences exist between patients with different vessels affected in vessel-specific ICAD. We have found that middle cerebral artery disease confers a lower mortality than vessel-specific ICAD in other intracranial vessels, asymptomatic disease follows a more benign course than symptomatic disease, andthat plaque progression or the detection of microemboli on transcranial Doppler may predict poor outcome. Given the expanding indications for treatment of ICAD and rapidly developing endovascular techniques to confront this disease, a thorough understanding of the natural history of ICAD aids the interventional neuroradiologist in determining when to treat and how to predict outcome in this patient population. | Ricardo J Komotar Christopher P Kellner Daniel M Raper Dorothea Strozyk Randall T Higashida Philip M Meyers | 2010 | World Journal of Radiology2010，2，5： | 8 |

| 10 | Carcinoma in situ in a 7 mm gallbladder polyp: Time to change current practice?显示文摘Detection of polypoid lesions of the gallbladder is increasing in conjunction with better imaging modalities. Accepted management of these lesions depends on their size and symptomatology. Polyps that are symptomatic and/or greater than 10 mm are generally removed, while smaller, asymptomatic polyps simply monitored. Here, a case of carcinoma-in-situ is presented in a 7 mm gallbladder polyp. A 25-year-old woman, who had undergone a routine cholecystectomy, was found to have an incidental 7 mm polyp containing carcinoma in situ. She had few to no risk factors to alert to her condition. There are few reported cases of cancer transformation in gallbladder polyps smaller than 10 mm reported in the literature. The overwhelming consensus, barring significant risk factors for cancer being present, is that such lesions should be monitored until they become symptomatic or develop signs suspicious for malignancy. In our patient's case this could have led to the possibility of missing a neoplastic lesion, which could then have gone on to develop invasive cancer. As gallbladder carcinoma is an aggressive cancer, this may have led to a tragic outcome. | David Kasle Amir A Rahnemai-Azar Shahida Bibi Vinaya Gaduputi Brian F Gilchrist Daniel T Farkas | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，9： | 8 |

| 12 | Adenosquamous carcinoma of the pancreas: Molecular characterization of 23 patients along with a literature review显示文摘Adenosquamous carcinoma of the pancreas(ASCP)is a rare entity. Like adenocarcinoma of the pancreas,overall survival is poor. Characteristics of ASCP include central tumor necrosis, along with osteoclasts and hypercalcemia. Various theories exist as to why this histological subtype exists, as normal pancreas tissue has no benign squamous epithelium. Due to the rarity of this disease, limited molecular analysis has been performed, and those reports indicate unique molecular features of ASCP. In this paper, we characterize 23 patients diagnosed with ASCP through molecular profiling using immunohistochemistry staining, fluorescent in situ hybridization, chromogenic in situ hybridization, and gene sequencing, Additionally, we provide a comprehensive literature review of what is known to date of ASCP.Molecular characterization revealed overexpression in MRP1(80%), MGMT(79%), TOP2A(75), RRM1(42%),TOPO1(42%), PTEN(45%), CMET(40%), and C-KIT(10%) among others. One hundred percent of samples tested were positive for KRAS mutations. This analysis shows heretofore unsuspected leads to be considered for treatments of this rare type of exocrine pancreas cancer. Molecular profiling may be appropriate to provide maximum information regarding the patient's tumor. Further work should be pursued to better characterize this disease. | Erkut Borazanci Sherri Z Millis Ron Korn Haiyong Han Clifford J Whatcott Zoran Gatalica Michael T Barrett Derek Cridebring Daniel D Von Hoff | 2015 | World Journal of Gastrointestinal Oncology2015，7，9： | 6 |

| 15 | Lensless diffractive imaging with ultra-broadbandtable-top sources: from infrared to extreme-ultravioletwavelengths显示文摘Lensless imaging is an approach to microscopy in which a high-resolution image of an object is reconstructed from one or more measured diffraction patterns,providing a solution in situations where the use of imaging optics is not possible.However,current lensless imaging methods are typically limited by the need for a light source with a narrow,stable and accurately known spectrum.We have developed a general approach to lensless imaging without spectral bandwidth limitations or sample requirements.We use two time-delayed coherent light pulses and show that scanning the pulse-to-pulse time delay allows the reconstruction of diffraction-limited images for all the spectral components in the pulse.In addition,we introduce an iterative phase retrieval algorithm that uses these spectrally resolved Fresnel diffraction patterns to obtain high-resolution images of complex extended objects.We demonstrate this two-pulse imaging method with octave-spanning visible light sources,in both transmission and reflection geometries,and with broadband extreme-ultraviolet radiation from a high-harmonic generation source.Our approach enables effective use of low-flux ultra-broadband sources,such as table-top high-harmonic generation systems,for high-resolution imaging. | Stefan Witte Vasco T Tenner Daniel WE Noom Kjeld SE Eikema | 2014 | Light(Science & Applications)2014，3，1： | 5 |
| 16 | Multiphase computed tomography radiomics of pancreatic intraductal papillary mucinous neoplasms to predict malignancy显示文摘BACKGROUND Intraductal papillary mucinous neoplasms(IPMNs)are non-invasive pancreatic precursor lesions that can potentially develop into invasive pancreatic ductal adenocarcinoma.Currently,the International Consensus Guidelines(ICG)for IPMNs provides the basis for evaluating suspected IPMNs on computed tomography(CT)imaging.Despite using the ICG,it remains challenging to accurately predict whether IPMNs harbor high grade or invasive disease which would warrant surgical resection.A supplementary quantitative radiological tool,radiomics,may improve diagnostic accuracy of radiological evaluation of IPMNs.We hypothesized that using CT whole lesion radiomics features in conjunction with the ICG could improve the diagnostic accuracy of predicting IPMN histology.AIM To evaluate whole lesion CT radiomic analysis of IPMNs for predicting malignant histology compared to International Consensus Guidelines.METHODS Fifty-one subjects who had pancreatic surgical resection at our institution with histology demonstrating IPMN and available preoperative CT imaging were included in this retrospective cohort.Whole lesion semi-automated segmentation was performed on each preoperative CT using Healthmyne software(Healthmyne,Madison,WI).Thirty-nine relevant radiomic features were extracted from each lesion on each available contrast phase.Univariate analysis of the 39 radiomics features was performed for each contrast phase and values were compared between malignant and benign IPMN groups using logistic regression.Conventional quantitative and qualitative CT measurements were also compared between groups,viaχ2(categorical)and Mann Whitney U(continuous)variables.RESULTS Twenty-nine subjects(15 males,age 71±9 years)with high grade or invasive tumor histology comprised the'malignant'cohort,while 22 subjects(11 males,age 70±7 years)with low grade tumor histology were included in the'benign'cohort.Radiomic analysis showed 18/39 precontrast,19/39 arterial phase,and 21/39 venous phase features differentiated malignant from benign IPMNs(P<0.05).Multivariate analysis including only ICG criteria yielded two significant variables:thickened and enhancing cyst wall and enhancing mural nodule<5 mm with an AUC(95%CI)of 0.817(0.709-0.926).Multivariable post contrast radiomics achieved an AUC(95%CI)of 0.87(0.767-0.974)for a model including arterial phase radiomics features and 0.834(0.716-0.953)for a model including venous phase radiomics features.Combined multivariable model including conventional variables and arterial phase radiomics features achieved an AUC(95%CI)of 0.93(0.85-1.0)with a 5-fold cross validation AUC of 0.90.CONCLUSION Multi-phase CT radiomics evaluation could play a role in improving predictive capability in diagnosing malignancy in IPMNs.Future larger studies may help determine the clinical significance of our findings. | Stuart L Polk Jung W Choi Melissa J McGettigan Trevor Rose Abraham Ahmed Jongphil Kim Kun Jiang Yoganand Balagurunathan Jin Qi Paola T Farah Alisha Rathi Jennifer B Permuth Daniel Jeong | 2020 | World Journal of Gastroenterology2020，26，24： | 5 |
| 17 | Crohn’s and colitis in children and adolescents显示文摘Crohn's disease and ulcerative colitis can be grouped as the inflammatory bowel diseases(IBD).These conditions have become increasingly common in recent years,including in children and young people.Although much is known about aspects of the pathogenesis of these diseases,the precise aetiology is not yet understood,and there remains no cure.Recent data has illustrated the importance of a number of genes-several of these are important in the onset of IBD in early life,including in infancy.Pain,diarrhoea and weight loss are typical symptoms of paediatric Crohn's disease whereas bloody diarrhoea is more typical of colitis in children.However,atypical symptoms may occur in both conditions:these include isolated impairment of linear growth or presentation with extra-intestinal manifestations such as erythema nodosum.Growth and nutrition are commonly compromised at diagnosis in both Crohn's disease and colitis.Consideration of possible IBD and completion of appropriate investi-gations are essential to ensure prompt diagnosis,thereby avoiding the consequences of diagnostic delay.Patterns of disease including location and progression of IBD in childhood differ substantially from adultonset disease.Various treatment options are available for children and adolescents with IBD.Exclusive enteral nutrition plays a central role in the induction of remission of active Crohn's disease.Medical and surgical therapies need to considered within the context of a growing and developing child.The overall management of these chronic conditions in children should include multi-disciplinary expertise,with focus upon maintaining control of gut inflammation,optimising nutrition,growth and quality of life,whilst preventing disease or treatment-related complications. | Andrew S Day Oren Ledder Steven T Leach Daniel A Lemberg | 2012 | World Journal of Gastroenterology2012，18，41： | 4 |
