| 1 | Endoscopic ultrasonography for gastric submucosal lesions显示文摘Gastric submucosal tumors(SMTs) are a rather frequent finding,occurring in about 0.36%of routine upper GIendoscopies.Endoscopic ultrasonography(EUS) has emerged as a reliable investigative procedure for evaluation of these lesions.Diagnostic EUS has the ability to differentiate intramural tumors from extraluminal compressions and can also show the layer of origin of gastric SMTs.Tumors can be further characterized by their layer of origin,echo pattern and margin.EUS-risk criteria of their malignant potential are presented,although the emergence of EUS-FNA has opened new indications for transmural tissue diagnosis and expanded the possibilities of EUS in SMTs of the stomach.Tissue diagnosis should address whether the SMT is a Gastrointestinal stromal tumour(GIST) or another tumor type and evaluate the malignant potential of a given GIST.However,there seems to be a lack of data on the optimal strategy in SMTs suspected to be GISTs with a negative EUS-FNA tissue diagnosis.The current management strategies,as well as open questions regarding their treatment are also presented. | Ioannis S Papanikolaou Konstantinos Triantafyllou Anastasia Kourikou Thomas Rsch | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，5： | 44 |
| 2 | Colonoscopy attachments for the detection of precancerous lesions during colonoscopy:A review of the literature显示文摘Although colonoscopy has been proven effective in reducing the incidence of colorectal cancer through the detection and removal of precancerous lesions, it remains an imperfect examination, as it can fail in detecting up to almost one fourth of existing adenomas. Among reasons accounting for such failures, is the inability to meticulously visualize the colonic mucosa located either proximal to haustral folds or anatomic curves, including the hepatic and splenic flexures. In order to overcome these limitations, various colonoscope attachments aiming to improve mucosal visualization have been developed. All of them-transparent cap, Endocuff, Endocuff Vision and Endorings-are simply mounted onto the distal tip of the scope. In this review article, we introduce the rationale of their development, present their mode of action and discuss in detail the effect of their implementation in the detection of lesions during colonoscopy. | Paraskevas Gkolfakis Georgios Tziatzios Eleftherios Spartalis Ioannis S Papanikolaou Konstantinos Triantafyllou | 2018 | World Journal of Gastroenterology2018，24，37： | 5 |
| 3 | Two cameras detect more lesions in the small-bowel than one显示文摘AIM:To explore the feasibility of dual camera capsule (DCC)small-bowel(SB)imaging and to examine if two cameras complement each other to detect more SB lesions.METHODS:Forty-one eligible,consecutive patients underwent DCC SB imaging.Two experienced investigators examined the videos and compared the total number of detected lesions to the number of lesions detected by each camera separately.Examination tolerability was assessed using a questionnaire.RESULTS:One patient was excluded.DCC cameras detected 68 positive findings(POS)in 20(50%)cases.Fifty of them were detected by the'yellow'camera,48 by the'green'and 28 by both cameras;44%(n=22)of the'yellow'camera’s POS were not detected by the'green'camera and 42%(n=20)of the'green' camera’s POS were not detected by the'yellow'camera.In two cases,only one camera detected significant findings.All participants had 216 findings of unknown significance(FUS).The'yellow','green'and both cameras detected 171,161,and 116 FUS,respectively;32%(n=55)of the'yellow'camera’s FUS were not detected by the'green'camera and 28%(n=45)of the'green'camera’s FUS were not detected by the 'yellow'camera.There were no complications related to the examination,and 97.6%of the patients would repeat the examination,if necessary.CONCLUSION:DCC SB examination is feasible and well tolerated.The two cameras complement each other to detect more SB lesions. | Konstantinos Triantafyllou Ioannis S Papanikolaou Kostis Papaxoinis Spiros D Ladas | 2011 | World Journal of Gastroenterology2011，17，11： | 5 |
| 4 | An unusual case of prolonged post-endoscopic retrograde cholangiopancreatography jaundice显示文摘Despite the effectiveness of endoscopic retrograde cholangiopancreatography(ERCP) for the treatment of choledocholithiasis, various complications have been described. We herein report the first case of prolonged postERCP jaundice due to toxicity of the contrast agent Iobitridol(~174;XENETIX, Guerbet, Roissy Cd G Cedex, France) in a patient who underwent ERCP with sphincterectomy and common bile duct stone removal. While clinical improvement and normalization of aminotransferases and cholestatic enzymes after the procedure, an unexplained increase of direct bilirubin was noticed. A second ERCP was performed one week later, excluding possible remaining choledocholithiasis. Nevertheless, serum direct bilirubin increased further up to 15 mg/d L. Other potential causes of direct hyperbilirubinemia were ruled out and patient's liver biopsy was compatible with drug-induced liver toxicity. Additionally, the cause-result time connection between the use of Iobitridol and bilirubin increase indicated the possibility of a toxic effect related to the repeated use of the particular contrast agent. Iobitridol, a contrast agent, can induce prolonged direct hyperbilirubinemia. | Georgios Tziatzios Paraskevas Gkolfakis Ioannis S Papanikolaou George Dimitriadis Konstantinos Triantafyllou | 2016 | Hepatobiliary & Pancreatic Diseases International2016，15，2： | 4 |
| 5 | Improved bowel preparation increases polyp detection and unmasks significant polyp miss rate显示文摘AIM: To retrospectively compare previous-day vs splitdose preparation in terms of bowel cleanliness and polyp detection in patients referred for polypectomy. METHODS: Fifty patients underwent two colonoscopies: one diagnostic in a private clinic and a second for polypectomy in a University Hospital. The latter procedures were performed within 12 wk of the index ones. Examinations were accomplished by two experienced endoscopists, different in each facility. Twenty-seven patients underwent screening/surveillance colonoscopy, while the rest were symptomatic. Previous day bowel preparation was utilized initially and splitdose for polypectomy. Colon cleansing was evaluated using the Aronchick scale. We measured the number of detected polyps, and the polyp miss rates per-polyp.RESULTS: Excellent/good preparation was reported in 38 cases with previous-day preparation(76%) vs 46 with split-dose(92%), respectively(P = 0.03). One hundred and twenty-six polyps were detected initially and 169 subsequently(P < 0.0001); 88 vs 126 polyps were diminutive(P < 0.0001), 25 vs 29 small(P = 0.048) and 13 vs 14 equal or larger than 10 mm. The miss rates for total, diminutive, small and large polyps were 25.4%, 30.1%, 13.7% and 6.6%, respectively. Multivariate analysis revealed that split-dose preparation was significantly associated(OR, P) with increased number of polyps detected overall(0.869, P < 0.001), in the right(0.418, P = 0.008) and in the left colon(0.452, P = 0.02). CONCLUSION: Split-dose preparation improved colon cleansing, enhanced polyp detection and unmasked significant polyp miss rates. | Ioannis S Papanikolaou Athanasios D Sioulas Nektarios Magdalinos Iosif Beintaris Lazaros-Dimitrios Lazaridis Dimitrios Polymeros Chrysoula Malli George D Dimitriadis Konstantinos Triantafyllou | 2015 | World Journal of Clinical Cases2015，3，10： | 4 |
| 6 | Role of pancreatic endoscopic ultrasonography in 2010显示文摘Endoscopic ultrasonography (EUS) was introduced 25 years ago aiming at better visualization of the pancreas compared to transabdominal ultrasonography. This update discusses the current evidence in 2010 concerning the role of EUS in the clinical management of patients with pancreatic disease. Major indications of EUS are:(1) Detection of common bile duct stones (e.g. in acute pancreatitis); (2) Detection of small exo-and endocrine pancreatic tumours; and (3) Performance of fine needle aspiration in pancreatic masses depending on therapeutic consequences. EUS seems to be less useful in cases of chronic pancreatitis and cystic pan-creatic lesions. Moreover the constant improvement of computed tomography has limited the role of EUS in pancreatic cancer staging. On the other hand,new therapeutic options are available due to EUS,such as pancreatic cyst drainage and celiac plexus neurolysis,offering a new field in which new techniques may arise. So the main goal of this review is to determine the exact role of EUS in a number of pancreatic and biliary diseases. | Ioannis S Papanikolaou Pantelis S Karatzas Konstantinos Triantafyllou Andreas Adler | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，10： | 3 |
