| 1 | Artificial intelligence in gastrointestinal endoscopy:The future is almost here显示文摘Artificial intelligence(AI) enables machines to provide unparalleled value in a myriad of industries and applications. In recent years, researchers have harnessed artificial intelligence to analyze large-volume, unstructured medical data and perform clinical tasks, such as the identification of diabetic retinopathy or the diagnosis of cutaneous malignancies. Applications of artificial intelligence techniques, specifically machine learning and more recently deep learning, are beginning to emerge in gastrointestinal endoscopy. The most promising of these efforts have been in computeraided detection and computer-aided diagnosis of colorectal polyps, with recent systems demonstrating high sensitivity and accuracy even when compared to expert human endoscopists. AI has also been utilized to identify gastrointestinal bleeding, to detect areas of inflammation, and even to diagnose certain gastrointestinal infections. Future work in the field should concentrate on creating seamless integration of AI systems with current endoscopy platforms and electronic medical records, developing training modules to teach clinicians how to use AI tools, and determining the best means for regulation and approval of new AI technology. | Muthuraman Alagappan Jeremy R Glissen Brown Yuichi Mori Tyler M Berzin | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，10： | 14 |
| 2 | Long-term irritable bowel syndrome symptom control with reintroduction of selected FODMAPs显示文摘AIM To investigate the long-term effect of dietary education on a low fermentable oligosaccharide, disaccharide and polyol(FODMAP) diet on irritable bowel syndrome(IBS) symptoms and quality of life(Qo L).METHODS Participants with IBS(Rome III) were randomized to two groups. Group I commenced a low FODMAP diet at baseline. At three months, group II, so far a comparator group, crossed over to a low FODMAP diet while group I started re-challenging foods. All patients completed the IBS SSS(IBS symptom severity scoring system, 0-500 points increasing with severity), IBS Qo L questionnaire(0-100 increasing with Qo L), a FODMAP specific food frequency questionnaire and provided a stool sample at baseline, three and six months for microbiome analysis.RESULTS Fifty participants were enrolled into group I(n = 23) or group II(n = 27). Participants in both groups were similar in baseline values but with more men in group I. There was a significantly lower IBS SSS(275.6 ± 63.6 to 128.8 ± 82.5 vs 246.8 ± 71.1 to 203.6 ± 70.1)(P < 0.0002) and increased Qo L(68.5 ± 18.0 to 83 ± 13.4 vs 72.9 ± 12.8 to 73.3 ± 14.4)(P < 0.0001) in group I vs group II at 3 mo. The reduced IBS SSS was sustained at 6 mo in group I(160 ± 102) and replicated in group II(124 ± 76). Fiber intake decreased on the low FODMAP diet(33 ± 17 g/d to 21 ± 8 g/d)(P < 0.01) and after re-introducing FODMAP containing foods increased again to 27 ± 9 g/d. There was no change seen in the intestinal microbiome when participants adopted a low FODMAP diet.CONCLUSION This study demonstrated that a reduction in FODMAPs improves symptoms in IBS and this improvement can be maintained while reintroducing FODMAPs. | Ruth M Harvie Alexandra W Chisholm Jordan E Bisanz Jeremy P Burton Peter Herbison Kim Schultz Michael Schultz | 2017 | World Journal of Gastroenterology2017，23，25： | 5 |
| 3 | Relationship between HER-2 overexpression and brain metastasis in esophageal cancer patients显示文摘AIM:To study if HER-2 overexpression by locally advanced esophageal cancers increase the chance of brain metastasis following esophagectomy.METHODS:We retrospectively reviewed the medical records of esophageal cancer patients who underwent esophagectomy at University of Iowa Hospitals and Clinics between 2000 and 2010.Data analyzed consisted of demographic and clinical variables.The brain metastasis tissue was assayed for HER-2 overexpression utilizing the FDA approved DAKO Hercept Test.RESULTS:One hundred and forty two patients were reviewed.Median age was 64 years(36-86 years).Eighty eight patients(62%) received neoadjuvant chemoradiotherapy.Pathological complete and partial responses were achieved in 17(19%) and 71(81%) patients.Cancer relapsed in 43/142(30%) patients.The brain was the first site of relapse in 9/43 patients(21%,95% CI:10%-36%).HER-2 immunohistochemistry testing of the brain metastasis tissue showed that 5/9(56%) cases overexpressed HER-2(3+ staining).CONCLUSION:HER-2 overexpression might be associated with increased risk of brain metastasis in esophageal cancer patients following esophagectomy.Further studies will be required to validate this observation. | Taher Abu Hejleh Barry R DeYoung Eric Engelman Jeremy M Deutsch Bridget Zimmerman Thorvardur R Halfdanarson Daniel J Berg Kalpaj R Parekh William R Lynch Mark D Iannettoni Sudershan Bhatia Gerald Clamon | 2012 | World Journal of Gastrointestinal Oncology2012，4，5： | 5 |
| 4 | Gastrointestinal perforation in metastatic colorectal cancer patients with peritoneal metastases receiving bevacizumab显示文摘AIM:To investigate the safety and efficacy of adding bevacizumab to first-line chemotherapy in metastatic colorectal cancer patients with peritoneal disease.METHODS:We compared rates of gastrointestinal perforation in patients with metastatic colorectal cancer and peritoneal disease receiving first-line chemotherapy with and without bevacizumab in three distinct cohorts:(1) the AGITG MAX trial(Phase Ⅲ randomised clinical trial comparing capecitabine vs capecitabine and bevacizumab vs capecitabine,bevacizumab and mitomycin C);(2) the prospective Treatment of Recurrent and Advanced Colorectal Cancer(TRACC) registry(any first-line regimen ± bevacizumab);and(3) two cancer centres in New South Wales,Australia [Macarthur Cancer Therapy Centre and Liverpool Cancer Therapy Centre(NSWCC) from January 2005 to Decenber 2012,(any first-line regimen ± bevacizumab).For the AGITG MAX trial capecitabine was compared to the other two arms(capecitabine/bevacizumab and capecitabine/bevacizumab/mitomycin C).In the AGITG MAX trial and the TRACC registry rates of gastrointestinal perforation were also collected in patients who did not have peritoneal metastases.Secondary endpoints included progression-free survival,chemotherapy duration,and overall survival.Time-toevent outcomes were estimated using the Kaplan-Meier method and compared using the log-rank test.RESULTS:Eighty-four MAX,179 TRACC and 69 NSWCC patients had peritoneal disease.There were no gastrointestinal perforations recorded in either the MAX subgroup or the NSWCC cohorts.Of the patients without peritoneal disease in the MAX trial,4/300(1.3%) in the bevacizumab arms had gastrointestinal perforations compared to 1/123(0.8%) in the capecitabine alone arm.In the TRACC registry 3/126(2.4%) patients who had received bevacizumab had a gastrointestinal perforation compared to 1/53(1.9%) in the chemotherapy alone arm.In a further analysis of patients without peritoneal metastases in the TRACC registry,the rate of gastrointestinal perforations was 9/369(2.4%) in the chemotherapy/bevacizumab group and 5/177(2.8%) in the chemotherapy alone group.The addition of bevacizumab to chemotherapy was associated with improved progression-free survival in all three cohorts:MAX 6.9 m vs 4.9 m,HR = 0.64(95%CI:0.42-1.02);P = 0.063;TRACC 9.1 m vs 5.5 m,HR = 0.61(95%CI:0.37-0.86);P = 0.009;NSWCC 8.7 m vs 6.8 m,HR = 0.75(95%CI:0.43-1.32);P = 0.32.Chemotherapy duration was similar across the groups.CONCLUSION:Patients with peritoneal disease do not appear to have an increased risk of gastrointestinal perforations when receiving first-line therapy with bevacizumab compared to systemic therapy alone. | Aflah Roohullah Hui-Li Wong Katrin M Sjoquist Peter Gibbs Kathryn Field Ben Tran Jeremy Shapiro Joe Mckendrick Desmond Yip Louise Nott Val Gebski Weng Ng Wei Chua Timothy Price Niall Tebbutt Lorraine Chantrill | 2015 | World Journal of Gastroenterology2015，21，17： | 3 |

| 6 | 钆特醇及钆喷替酸葡甲胺在1.5、3.0 TMR下鼠脑胶质瘤模型增强扫描中的应用比较研究显示文摘目的 对比钆特醇及Gd-DTPA在1.5及3.0 T MR下的增强效果,比较两者在增强扫描中的应用价值.方法 42只CDF Fisher 344雄性大鼠,采用经皮导管脑内接种胶质瘤细胞,培育1周,制作鼠脑胶质瘤模型.将大鼠采用数字表法随机分为4组,分别为12、10、10、10只,进行1.5及3.0 T MR下注射钆特醇及Gd-DTPA增强效果对比、注射钆特醇在1.5及3.0 T两种场强下增强效果对比、1.5 T MR下使用标准剂量钆特醇与3.0 T下使用半剂量增强效果对比.两次扫描间隔24 h.选取注射对比剂前及注射后第1、3、5、7、9分钟时间点的T1加权图像,利用影像工作站分析计算各图像的信噪比(signal to noise ratio,SNR),对比噪声比(contrast to noise ratio,CNR)及对比增强比(contrast enhancement,CE),所得数据选用Student配对双尾t检验行统计学分析.结果 1.5 T MR下,注射Gd-DTPA后各时间点图像SNR、CNR和CE平均值分别为54.4±3.2、17.0±3.3、20.8±3.4;注射钆特醇后各值分别为53.2±3.2、17.2±3.1、20.8±3.2,两者差异无统计学意义(t值分别为2.247、0.403、0.076,P值均>0.05).3.0 T MR下,注射Gd-DTPA后各时间点图像SNR、CNR和CE平均值分别为94.8±7.1、38.0±6.0、45.0±6.3;注射钆特醇后各值分别为95.5±2.9、37.2±2.7、45.6±2.8,两者差异亦无统计学意义(t值分别为0.303、0.573、0.357,P值均>0.05).注射钆特醇在1.5 T MR下增强扫描后各时间点图像SNR、CNR和CE平均值分别为51.9±3.0、15.6±3.0、18.6±3.0;在3.0 T MR下图像各值分别为86.1±4.9、27.4±5.0、37.3±5.3,均高于1.5 T MRI图像,差异有统计学意义(t值分别为36.227、11.977、17.106,P值均<0.05).1.5 T MR下注射标准剂量钆特醇增强扫描后,各时间点图像SNR、CNR和CE平均值分别为53.8±1.6、17.7±1.7、20.3±1.6;3.0 T MR下注射半剂量钆特醇增强图像各值分别为72.2±2.4、15.4±2.4、21.1±2.4,两者SNR、CNR均值差异有统计学意义(t值分别为31.503、5.137,P值均<0.05),而两者CE均值差异无统计学意义(t=2.033,P>0.05).结论 利用鼠脑胶质瘤模型,在1.5及3.0 T MR下注射钆特醇和Gd-DTPA行增强扫描,两者增强效果无明显差异;3.0 T MR下注射钆特醇行增强扫描,效果明显优于在1.5 T条件下使用;3.0 T MR下使用半剂量钆特醇与在1.5 T下使用标准剂量增强效果相仿,同样能取得满意的增强效果.因此,使用钆特醇可在保证增强效果的同时,在一定程度上降低使用MRI对比剂的风险,增加安全性. | 艾飞 Val M Runge John N Morelli Lan.Vu Jeremy Cannel Alan T Loynachan 漆剑频 李小明 | 2010 | 中华放射学杂志2010，44，11： | 2 |
| 7 | Management of patients with a short bowel显示文摘There are two common types of adult patient with a short bowel, those with jejunum in continuity with a functioning colon and those with a jejunostomy. Both groups have potential problems of undemutrition, but this is a greater problem in those without a colon, as they do not derive energy from anaerobic bacterial fermentation of carbohydrate to short chain fatty acids in the colon. Patients with a jejunostomy have major problems of dehydration,sodium and magnesium depletion all due to a large volume of stomal output. Both types of patient have lost at least 60cm of terminal ileum and so will become deficient of vitamin B12. Both groups have a high prevalence of gallstones (45%) resulting from periods of biliary stasis. Patients with a retained colon have a 25% chance of developing calcium oxalats renal atones and they may have problems with D (-)lactic acidosis. The survival of patients with a short bowel,even if they need long-term parenteral nutrition, is good. | Jeremy M D Nightingale | 2001 | World Journal of Gastroenterology2001，7，6： | 2 |
