| 1 | Endoscopic management of chronic radiation proctitis显示文摘Chronic radiation proctopathy occurs in 5%-20% of patients following pelvic radiotherapy. Although many cases resolve spontaneously,some lead to chronic symptoms including diarrhea,tenesmus,urgency and persistent rectal bleeding with iron deficiency anemia requiring blood transfusions. Treatments for chronic radiation proctitis remain unsatisfactory and the basis of evidence for various therapies is generally insuff icient. There are very few controlled or prospective trials,and comparisons between therapies are limited because of different evaluation methods. Medical treatments,including formalin,topical sucralfate,5-amino salicylic acid enemas,and short chain fatty acids have been used with limited success.Surgical management is associated with high morbidity and mortality. Endoscopic therapy using modalities such as the heater probe,neodymium:yttrium-aluminium-garnet laser,potassium titanyl phosphate laser and bipolar electrocoagulation has been reported to be of some benef it,but with frequent complications.Argon plasma coagulation is touted to be the preferred endoscopic therapy due to its eff icacy and safety profile.Newer methods of endoscopic ablation such as radiofrequency ablation and cryotherapy have been recently described which may afford broader areas of treatment per application,with lower rate of complications.This review will focus on endoscopic ablation therapies,including such newer modalities,for chronic radiation proctitis. | Tarun Rustagi Hiroshi Mashimo | 2011 | World Journal of Gastroenterology2011，17，41： | 8 |

| 8 | Endoscopic treatment of gastroparesis显示文摘Gastroparesis has traditionally been a largely medically managed disease with refractory symptoms typically falling under the umbrella of the surgical domain.Surgical options include, but are not limited to, gastrostomy,jejunostomy, pyloromyotomy, or pyloroplasty,and the Food and Drug Administration approvedgastric electrical stimulation implantation. Endoscopic management of gastroparesis most commonly involves intrapyloric botulinum toxin injection; however, there exists a variety of endoscopic approaches on the horizon that have the potential to radically shift standard of care.Endoscopic management of gastroparesis seeks to treat delayed gastric emptying with a less invasive approach compared to the surgical approach. This review will serve to highlight such innovative and potentially transformative, endoscopic interventions available to gastroenterologists in the management of gastroparesis. | Thomas R McCarty Tarun Rustagi | 2015 | World Journal of Gastroenterology2015，21，22： | 1 |

| 10 | Sessile serrated adenomas in the proximal colon are likely to be flat,large and occur in smokers显示文摘AIM:To examine the epidemiology and the morphology of the proximal sessile serrated adenomas(SSAs).METHODS:We conducted a retrospective study to identify patients with SSAs using a university-based hospital pathology database query from January 2007to April 2011.Data collected included:age,gender,ethnicity,body mass index,diabetes,smoking,family history of colorectal cancer,aspirin,and statin use.We collected data on morphology of SSAs including site(proximal or distal),size,and endoscopic appearance(flat or protuberant).We also compared proximal SSAs to proximal tubular adenomas detected during same time period.RESULTS:One hundred and twenty patients with SSAs were identified:61%were distal and 39%were proximal SSAs.Proximal SSAs were more likely to be flat than distal(100%vs 78%respectively;P=0.0001).Proximal SSAs were more likely to occur in smokers(OR=2.63;95%CI:1.17-5.90;P=0.02)and in patients with family history of colorectal cancer(OR=4.72;95%CI:1.43-15.55;P=0.01)compared to distal.Proximal SSAs were statistically more likely to be≥6 mm in size(OR=2.94;P=0.008),and also more likely to be large(≥1 cm)(OR=4.55;P=0.0005)compared to the distal lesions.Smokers were more likely to have proximal(P=0.02),flat(P=0.01)and large(P=0.007)SSAs compared to non-smokers.Compared to proximal tubular adenomas,proximal SSAs were more likely to be large and occur in smokers.CONCLUSION:Proximal SSAs which accounted for two-fifths of all SSAs were more likely to present as flat lesions,larger SSAs,and were more likely to occur in smokers and in patients with family history of colorectal cancer.Our data has implications for colorectal cancer screening. | Tarun Rustagi Priya Rangasamy Matthew Myers Melinda Sanders Haleh Vaziri George Y Wu John W Birk Petr Protiva Joseph C Anderson | 2013 | World Journal of Gastroenterology2013，19，32： | 1 |
