| 2 | 男性包皮环切对降低生殖道感染和预防生殖道肿瘤的意义显示文摘越来越多的的研究结果证明,男性包皮环切显著降低包皮龟头炎和尿路感染及其他生殖道感染、降低HIV和HPV以及HSV-2与其他性传播疾病感染风险,对生殖道肿瘤,如子宫颈癌、阴茎癌和前列腺癌具有预防作用。目前在中国包皮环切率低于5%。商环包皮环切术在非洲的临床评估试验和大样本随机对照试验结果证实,商环具有安全性好、可接受性和满意度高。世界卫生组织(WHO)和联合国艾滋病规划署(UNAIDS)已将男性包皮环切推荐为艾滋病预防策略的重要干预措施之一,中国应该大力提倡安全的包皮环切术,从而降低男性及其女性伴侣生殖道感染、预防生殖道肿瘤,对改善全民生殖健康具有长期影响和深远意义。研究男性包皮环切对公共卫生的深远影响将成为今后泌尿男科工作的重点之一。 | 赵福军 李石华 吕年青 Richard LEE 彭弋峰 程峰 李铮 许豪勤 Mark BARONE Marc GOLDSTEIN 夏术阶 | 2014 | 中华男科学杂志2014，20，11： | 28 |
| 3 | Transarterial chemoembolization:Evidences from the literature and applications in hepatocellular carcinoma patients显示文摘Transarterial chemoembolization(TACE) is the current standard of care for patients with large or multinodular hepatocellular carcinoma(HCC), preserved liver function, absence of cancer-related symptoms and no evidence of vascular invasion or extrahepatic spread(i.e., those classified as intermediate stage according to the Barcelona Clinic Liver Cancer staging system). The rationale for TACE is that the intra-arterial injection of a chemotherapeutic drug such as doxorubicin or cisplatin followed by embolization of the blood vessel will result in a strong cytotoxic effect enhanced by ischemia. However, TACE is a very heterogeneous operative technique and varies in terms of chemotherapeutic agents, treatment devices and schedule. In order to overcome the major drawbacks of conventional TACE(c TACE), non-resorbable drug-eluting beads(DEBs) loaded with cytotoxic drugs have been developed. DEBs are able to slowly release the drug upon injection and increase the intensity and duration of ischemia while enhancing the drug delivery to the tumor. Unfortunately, despite the theoretical advantages of this new device and the promising results of the pivotal studies, definitive data in favor of its superiority over c TACE are still lacking. The recommendation for TACE as the standard-of-care for intermediate-stage HCC is based on the demonstration of improved survival compared with best supportive care or suboptimal therapies in a meta-analysis of six randomized controlled trials, but other therapeutic options(namely, surgery and radioembolization) proved competitive in selected subsets of intermediate HCC patients. Other potential fields of application of TACE in hepato-oncology are the pre-transplant setting(as downstaging/bridging treatment) and the early stage(in patients unsuitable to curative therapy). The potential of TACE in selectedadvanced patients with segmental portal vein thrombosis and preserved liver function deserves further reports. | Antonio Facciorusso Raffaele Licinio Nicola Muscatiello Alfredo Di Leo Michele Barone | 2015 | World Journal of Hepatology2015，7，16： | 25 |

| 5 | Non-polypoid colorectal neoplasms:Classification,therapy and follow-up显示文摘In the last years,an increasing interest has been raised on non-polypoid colorectal tumors(NPT) and in particular on large flat neoplastic lesions beyond 10 mm tending to grow laterally,called laterally spreading tumors(LST).LSTs and large sessile polyps have a greater frequency of high-grade dysplasia and local invasiveness as compared to pedunculated lesions of the same size and usually represent a technical challenge for the endoscopist in terms of either diagnosis and resection.According to the Paris classification,NPTs are distinguished in slightly elevated(0-Ⅱa,less than 2.5 mm),flat(0-Ⅱb) or slightly depressed(0-Ⅱc).NPTs are usually flat or slightly elevated and tend to spread laterally while in case of depressed lesions,cell proliferation growth progresses in depth in the colonic wall,thus leading to an increased risk of submucosal invasion(SMI) even for smaller neoplasms.NPTs may be frequently missed by inexperienced endoscopists,thus a careful training and precise assessment of all suspected mucosal areas should be performed.Chromoendoscopy or,if possible,narrow-band imaging technique should be considered for the estimation of SMI risk of NPTs,and the characterization of pit pattern and vascular pattern may be useful to predict the risk of SMI and,therefore,to guide the therapeutic decision.Lesions suitable to endoscopic resection are those confined to the mucosa(or superficial layer of submucosa in selected cases) whereas deeper invasion makes endoscopic therapy infeasible.Endoscopic mucosal resection(EMR,piecemeal for LSTs > 20 mm,en bloc for smaller neoplasms) remains the first-line therapy for NPTs,whereas endoscopic submucosal dissection in high-volume centers or surgery should be considered for large LSTs for which en bloc resection is mandatory and cannot be achieved by means of EMR.After piecemeal EMR,follow-up colonoscopy should be performed at 3 mo to assess resection completeness.In case of en bloc resection,surveillance colonoscopy should be scheduled at 3 years for adenomatous lesions ≥ 1 cm,or in presence of villous features or high-grade dysplasia patients(regardless of the size),while less intensive surveillance(colonoscopy at 5-10 years) is needed in case of single(or two) NPT < 1 cm presenting tubular features or low-grade dysplasia at histology. | Antonio Facciorusso Matteo Antonino Marianna Di Maso Michele Barone Nicola Muscatiello | 2015 | World Journal of Gastroenterology2015，21，17： | 20 |
| 6 | Probiotic monotherapy and Helicobacter pylori eradication: A systematic review with pooled-data analysis显示文摘AIM To define probiotic monotherapy effect on Helicobacter pylori(H. pylori) status by performing a systematic review.METHODS Methods of analysis and inclusion criteria were based on PRISMA recommendations. Relevant publications were identified by searching Pub Med, MEDLINE, Science Direct, and EMBASE. The end-point was to estimate eradication rate and urea breath test delta value before and after probiotic monotherapy across all studies and, overall, with a pooled data analysis. Adverse events of probiotic therapy were evaluated. The data were expressed as proportions/percentages, and 95%CIs were calculated. For continuous variables, we evaluated the weighted mean difference. Odd ratios(ORs) were calculated according to the Peto method for the comparison of eradication rates between probiotics and placebo.RESULTS Eleven studies were selected. Probiotics eradicated H. pylori in 50 out of 403 cases. The mean weighted eradication rate was 14%(95%CI: 2%-25%, P =0.02). Lactobacilli eradicated the bacterium in 30 out of 235 patients, with a mean weighted rate of 16%(95%CI: 1%-31%). Saccharomyces boulardii achieved eradication in 6 out of 63 patients, with a pooled eradication rate of 12%(95%CI: 0%-29%). Multistrain combinations were effective in 14 out of 105 patients, with a pooled eradication rate of 14%(95%CI: 0%-43%). In the comparison of probiotics vs placebo, we found an OR of 7.91 in favor of probiotics(95%CI: 2.97-21.05, P < 0.001). Probiotics induced a mean reduction in delta values higher than placebo(8.61% with a 95%CI: 5.88-11.34, vs 0.19% for placebo, P < 0.001). Finally, no significant difference in adverse events was found between probiotics and placebo(OR = 1, 95%CI: 0.06-18.08).CONCLUSION Probiotics alone show a minimal effect on H. pylori clearance, thus suggesting a likely direct role. | Giuseppe Losurdo Rossella Cubisino Michele Barone Mariabeatrice Principi Gioacchino Leandro Enzo Ierardi Alfredo Di Leo | 2018 | World Journal of Gastroenterology2018，24，1： | 18 |
| 7 | Computed tomography findings of pneumatosis and portomesenteric venous gas in acute bowel ischemia显示文摘AIM:To use more representative sample size to evaluate whether computed tomography(CT)scan evidence of the concomitant presence of pneumatosis and portomesenteric venous gas is a predictor of transmural bowel necrosis.METHODS:Data from 208 patients who were referred for a diagnosis of bowel ischemia were retrospectively reviewed.Only patients who underwent a surgical intervention following a diagnosis of bowel ischemia who also had a post-operative histological confirmation of such a diagnosis were included.Patients were split into two groups according to the presence of histological evidence of transmural bowel ischemia(case group)or partial bowel ischemia(control group).CT images were reviewed for findings of ischemia,including mural thickening,pneumatosis,bowel distension,portomesenteric venous gas and arterial or venous thrombi.RESULTS:A total of 248 subjects who underwent surgery for bowel ischemia were identified.Among the208 subjects enrolled in our study,transmural bowel necrosis was identified in 121 subjects(case group),and partial bowel necrosis was identified in 87 subjects(control group).Based on CT findings,including mural thickening,bowel distension,pneumatosis,pneumatosis plus portomesenteric venous gas and presence of thrombi or emboli,there were no significant differences between the case and control groups.The concomitant presence of pneumatosis and porto-mesenteric venous gas showed an odds ratio of 1.95(95%CI:0.491-7.775,P=0.342)for the presence of transmural necrosis.The presence of pneumatosis plus porto-mesenteric venous gas exhibited good specificity(83%)but low sensitivity(17%)in the identification of transmural bowel infarction.Accordingly,the positive and negative predictive values were 60% and 17%,respectively.CONCLUSION:Although pneumatosis plus porto-mesenteric venous gas is associated with bowel ischemia,we have demonstrated that their co-occurrence cannot be used as diagnostic signs of transmural necrosis. | Marco Milone Matteo Nicola Dario Di Minno Mario Musella Paola Maietta Vittorio Iaccarino Giovanni Barone Francesco Milone | 2013 | World Journal of Gastroenterology2013，19，39： | 15 |
| 8 | Optimizing proton pump inhibitors in Helicobacter pylori treatment:Old and new tricks to improve effectiveness显示文摘The survival and replication cycle of Helicobacter pylori(H.pylori)is strictly dependant on intragastric pH,since H.pylori enters replicative phase at an almost neutral pH(6-7),while at acid pH(3-6)it turns into its coccoid form,which is resistant to antibiotics.On these bases,it is crucial to increase intragastric pH by proton pump inhibitors(PPIs)when an antibiotic-based eradicating therapy needs to be administered.Therefore,several tricks need to be used to optimize eradication rate of different regimens.The administration of the highest dose as possible of PPI,by doubling or increasing the number of pills/day,has shown to be able to improve therapeutic outcome and has often proposed in rescue therapies,even if specific trials have not been performed.A pre-treatment with PPI before starting antibiotics does not seem to be effective,therefore it is discouraged.However,the choice of PPI molecule could have a certain weight,since second-generation substances(esomeprazole,rabeprazole)are likely more effective than those of first generation(omeprazole,lansoprazole).A possible explanation is due to their metabolism,which has been proven to be less dependent on cytochrome P450(CYP)2C19 genetic variables.Finally,vonoprazan,a competitive inhibitor of H+/K+-ATPase present on luminal membrane of gastric parietal cells has shown the highest efficacy,due to both its highest acid inhibition power and rapid pharmacologic effect.However current data come only from Eastern Asia,therefore its strong power needs to be confirmed outside this geographic area in Western countries as well as related to the local different antibiotic resistance rates. | Enzo Ierardi Giuseppe Losurdo Rosa Federica La Fortezza Mariabeatrice Principi Michele Barone Alfredo Di Leo | 2019 | World Journal of Gastroenterology2019，25，34： | 15 |

| 12 | Outcome of stenting in biliary and pancreatic benign and malignant diseases:A comprehensive review显示文摘Endoscopic stenting has become a widely method for the management of various malignant and benign pancreatico-biliary disorders. Biliary and pancreatic stents are devices made of plastic or metal used primarily to establish patency of an obstructed bile or pancreatic duct and may also be used to treat biliary or pancreatic leaks,pancreatic fluid collections and to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis. In this review,relevant literature search and expert opinions have been used to evaluate the outcome of stenting in biliary and pancreatic benign and malignant diseases. | Benedetto Mangiavillano Nico Pagano Todd H Baron Carmelo Luigiano | 2015 | World Journal of Gastroenterology2015，21，30： | 8 |
| 13 | Role of functional imaging in the development and refinement of invasive neuromodulation for psychiatric disorders显示文摘Deep brain stimulation(DBS) is emerging as a pow-erful tool for the alleviation of targeted symptoms in treatment-resistant neuropsychiatric disorders. Despite the expanding use of neuropsychiatric DBS, the mecha-nisms responsible for its effects are only starting to be elucidated. Several modalities such as quantitative elec-troencephalography as well a intraoperative recordings have been utilized to attempt to understand the under-pinnings of this new treatment modality, but functional imaging appears to offer several unique advantages. Functional imaging techniques like positron emission tomography, single photon emission computed tomog-raphy and functional magnetic resonance imaging have been used to examine the effects of focal DBS on activ-ity in a distributed neural network. These investigations are critical for advancing the field of invasive neuro-modulation in a safe and effective manner, particularly in terms of defining the neuroanatomical targets and refining the stimulation protocols. The purpose of this review is to summarize the current functional neuroim-aging findings from neuropsychiatric DBS implantation for three disorders: treatment-resistant depression, obsessive-compulsive disorder, and Tourette syndrome. All of the major targets will be discussed(Nucleus ac-cumbens, anterior limb of internal capsule, subcallosal cingulate, Subthalamic nucleus, Centromedial nucleus of the thalamus-Parafasicular complex, frontal pole, and dorsolateral prefrontal cortex). We will also address some apparent inconsistencies within this literature, and suggest potential future directions for this promis-ing area. | Nolan R Williams Joseph J Taylor Kayla Lamb Colleen A Hanlon E Baron Short Mark S George | 2014 | World Journal of Radiology2014，6，10： | 6 |
| 14 | Biliary and pancreatic stenting:Devices and insertiontechniques in therapeutic endoscopic retrogradecholangiopancreatography and endoscopic ultrasonography显示文摘Stents are tubular devices made of plastic or metal. Endoscopic stenting is the most common treatment for obstruction of the common bile duct or of the main pancreatic duct, but also employed for the treatment of bilio-pancreatic leakages, for preventing post- endoscopic retrograde cholangiopancreatography pancreatitis and to drain the gallbladder and pancreatic fluid collections. Recent progresses in techniques of stent insertion and metal stent design are represented by new, fullycovered lumen apposing metal stents. These stents are specifically designed for transmural drainage, with a saddle-shape design and bilateral flanges, to provide lumen-to-lumen anchoring, reducing the risk of migration and leakage. This review is an update of the technique of stent insertion and metal stent deployment, of the most recent data available on stent types and characteristics and the new applications for biliopancreatic stents. | Benedetto Mangiavillano Nico Pagano Todd H Baron Monica Arena Giuseppe Iabichino Pierluigi Consolo Enrico Opocher Carmelo Luigiano | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，3： | 6 |
| 15 | ERCP for the treatment of bile leak after partial hepatectomy and fenestration for symptomatic polycystic liver disease显示文摘AIM: To describe endoscopic treatment of bile leaks in these patients and to identify risk factors in these patients which can predict the development of bile leaks. METHODS: Retrospective case-control study examining consecutive patients who underwent partial hepatectomy for polycystic liver disease (PLD) and developed a postoperative bile leak managed endoscopically over a ten year period. Each case was matched with two controls with PLD who did not develop a postoperative bile leak. RESULTS: Ten cases underwent partial hepatectomy with fenestration for symptoms including abdominal distention, pain and nausea. Endoscopic retrograde cholangiopancreatography (ERCP) showed anatomic abnormalities in 1 case. A biliary sphincterotomy was performed in 4 cases. A plastic biliary stent was placed with the proximal end at the site of the leak in 9 cases; in 1 case two stents were placed. The overall success rate of ERCP to manage the leak was 90%. There were no significant differences in age, gender, comorbidities, duration of symptoms, history of previous surgery or type of surgery performed between cases and controls. CONCLUSION: ERCP with stent placement is safe and effective for management of post-hepatectomy bile leak in patients with PLD. | Nayantara Coelho-Prabhu David M Nagorney Todd H Baron | 2012 | World Journal of Gastroenterology2012，18，28： | 6 |

| 17 | New fecal test for non-invasive Helicobacter pylori detection:A diagnostic accuracy study显示文摘AIM To assess the diagnostic accuracy of a new fecal test for detecting Helicobacter pylori(H. pylori), using ^(13)Curea breath test as the reference standard, and explore bacterial antibiotic resistance. METHODS We conducted a prospective two-center diagnostic test accuracy study. We enrolled consecutive people≥ 18 years without previous diagnosis of H. pylori infection, referred for dyspepsia between February and October 2017. At enrollment, all participants underwent 13 C-urea breath test. Participants aged over 50 years were scheduled to undergo upper endoscopy with histology. Participants collected stool samples 1-3 d after enrollment for a new fecal investigation(THD fecal test). The detection of bacterial 23 S rRNA subunit gene indicated H. pylori infection. We also used the index diagnostic test to examine mutations conferring resistance to clarithromycin and levofloxacin. Independent investigators analyzed index test and reference test standard results blinded to the other test findings. We estimated sensitivity, specificity, positive(PPV) and negative(NPV) predictive value, diagnostic accuracy, positive and negative likelihood ratio(LR), together with 95% confidence intervals(CI).RESULTS We enrolled 294 consecutive participants(age: Median 37.0 years, IQR: 29.0-46.0 years; men: 39.8%). Ninetyfive(32.3%) participants had a positive ^(13)C-urea breath test. Twenty-three(7.8%) participants underwent upper endoscopy with histology, with a full concordance between ^(13)C-urea breath test and histology in detecting H. pylori infection. Four(1.4%) out of the 294 participants withdrew from the study after the enrollment visit and did not undergo THD fecal testing. In the 290 participants who completed the study, the THD fecal test sensitivity was 90.2%(CI: 84.2%-96.3%), specificity 98.5%(CI:96.8%-100%), PPV 96.5%(CI: 92.6%-100%), NPV 95.6%(CI: 92.8%-98.4%), accuracy 95.9%(CI: 93.6%-98.2%), positive LR 59.5(CI: 19.3-183.4), negative LR 0.10(CI: 0.05-0.18). Out of 83 infected participants identified with the THD fecal test, 34(41.0%) had bacterial genotypic changes consistent with antibiotic-resistant H. pylori infection. Of these, 27(32.5%) had bacterial strains resistant to clarithromycin, 3(3.6%) to levofloxacin, and 4(4.8%) to both antibiotics. CONCLUSION The THD fecal test has high performance for the non-invasive diagnosis of H. pylori infection while additionally enabling the assessment of bacterial antibiotic resistances. | Andrea Iannone Floriana Giorgio Francesco Russo Giuseppe Riezzo Bruna Girardi Maria Pricci Suetonia C Palmer Michele Barone Mariabeatrice Principi Giovanni FM Strippoli Alfredo Di Leo Enzo Ierardi | 2018 | World Journal of Gastroenterology2018，24，27： | 5 |
| 18 | HBsAg clearance by Peg-interferon addition to a long-term nucleos(t)ide analogues therapy显示文摘The ideal endpoint of hepatitis B virus(HBV)antiviral therapy is HBsAg loss,a difficult goal to obtain,especially in HBeAg negative patients.Herein,we report the results obtained by the addition of peg-interferonα-2a to a long-lasting nucleos(t)ide analogues therapy in a HBeAg negative,genotype D patient with steadily HBV-DNA negative/HBsAg positive values.In 2002,our Caucasian 44-year-old male patient received lamivudine and,4 years later,added adefovir because of a virological breakthrough.In 2011,considering his young age,liver stiffness(4.3 kPa)and HBsAg levels(3533IU/mL),we added Peg-interferonα-2a for six months(3in combination with nucleos(t)ide analogues followed by 3 mo of Peg-interferonα-2a monotherapy).A decrease of HBsAg levels was observed after 1 mo(1.21log)of Peg-interferon and 3 mo(1.88 log)after the discontinuation of all drugs.Later,a complete clearance of HBsAg was obtained with steadily undetectable HBVDNA serum levels(<9 IU/mL).HBsAg clearance by the addition of a short course of Peg-interferonα-2a represents an important result with clinical and pharmacoeconomic implications,considering that nucleos(t)ide analogues therapy in HBeAg negative chronic hepatitis B patients is considered a long-lasting/life-long treatment. | Michele Barone Andrea Iannone Alfredo Di Leo | 2014 | World Journal of Gastroenterology2014，20，26： | 5 |
| 19 | Endoscopic management of benign biliary strictures显示文摘Endoscopic management of biliary obstruction has evolved tremendously since the introduction of flexible fiberoptic endoscopes over 50 years ago. For the last several decades, endoscopic retrograde cholangiopancreatography(ERCP) has become established as the mainstay for definitively diagnosing and relieving biliary obstruction. In addition, and more recently, endoscopic ultrasonography(EUS) has gained increasing favor as an auxiliary diagnostic and therapeutic modality in facilitating decompression of the biliary tree. Here, we provide a review of the current and continually evolving role of gastrointestinal endoscopy, including both ERCP and EUS, in the management of biliary obstruction with a focus on benign biliary strictures. | Kavel H Visrodia James H Tabibian Todd H Baron | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，11： | 5 |
| 20 | Role of colonoscopy in the diagnostic work-up of bowel endometriosis显示文摘AIM:To evaluate the accuracy of colonoscopy for the prediction of intestinal involvement in deep pelvic endometriosis.METHODS:This prospective observational study was performed between September 2011 and July 2014.Only women with both a clinical and imaging diagnosis of deep pelvic endometriosis were included.The study was approved by the local ethics committee and written informed consent was obtained in all cases.Both colonoscopy and laparoscopy were performed by expert surgeons with a high level of expertise with these techniques.Laparoscopy was performed within4 wk of colonoscopic examination.All hypothetical colonoscopy findings(eccentric wall thickening with or without surface nodularities and polypoid lesions with or without surface nodularities of endometriosis)were compared with laparoscopic and histological findings.We calculated the sensitivity,specificity,positive predictive value and negative predictive value for the presence of colonoscopic findings of intestinal endometriosis.RESULTS:A total of 174 consecutive women aged between 21-42 years with a diagnosis of deep pelvic endometriosis who underwent colonoscopy andsurgical intervention were included in our analysis.In 76 of the women(43.6%),intestinal endometrial implants were found at surgery and histopathological examination.Specifically,38 of the 76 lesions(50%)were characterized by the presence of serosal bowel nodules;28 of the 76 lesions(36.8%)reached the muscularis layer;8 of the 76 lesions(10.5%)reached the submucosa;and 2 of the 76 lesions(2.6%)reached the mucosa.Colonoscopic findings suggestive of intestinal endometriosis were detected in 7 of the174(4%)examinations.Colonoscopy failed to diagnose intestinal endometriosis in 70 of the 76 women(92.1%).A colonoscopic diagnosis of endometriosis was obtained in all cases of mucosal involvement,in 3of 8 cases(37.5%)of submucosal involvement,in no cases of muscularis layer involvement and in 1 of 38cases(2.6%)of serosa involvement.The sensitivity,specificity,positive predictive and negative predictive values of colonoscopy for the diagnosis of intestinal endometriosis were 7%,98%,85%and 58%,respectively.CONCLUSION:Being an invasive procedure,colonoscopy should not be routinely performed in the diagnostic work-up of bowel endometriosis. | Marco Milone Antonio Mollo Mario Musella Paola Maietta Loredana Maria Sosa Fernandez Olena Shatalova Alessandro Conforti Gianni Barone Giuseppe De Placido Francesco Milone | 2015 | World Journal of Gastroenterology2015，21，16： | 5 |
