| 1 | Diagnosis of subepithelial tumors in the upper gastrointestinal tract by endoscopic ultrasonography显示文摘Endoscopic ultrasonography(EUS) is the most accurate procedure for detecting and diagnosing subepithelial tumors,due to its higher sensitivity and specificity than other imaging modalities.EUS can characterize lesions by providing information on echogenic origin,size,borders,homogeneity,and the presence of echogenic or anechoic foci.Linear echoendoscopes,and recently also electronic radial echoendoscopes,can be used with color Doppler or power Doppler to assess the vascular signals from subepithelial masses,and thus permit the differentiation of vascular structures from cysts,as well as the assessment of the tumor blood supply.However,the diagnostic accuracy of EUS imaging alone has been shown to be low in subepithelial lesions with 3rd and 4th layers.It is also difficult to differentiate exactly between benign and malignant tumors and to gain an accurate picture of histology using EUS.On the other hands,EUS guided fine needle aspiration(EUS-FNA) can provide samples for cytologic or histologic analysis.Hypoechoic lesions of the 3rd and the 4th EUS layers,more than in 1 cm diameter are recommended,and histologic confirmation using endoscopic submucosal resection or EUSFNA should be obtained when possible.Therefore,EUSFNA plays an important role in the clinical management of subepithelial tumors.Furthermore improvements in endoscopic technology are expected to be more useful modalities in differential diagnosis and discrimination between benign and malignant subepithelial | Hiroki Sakamoto Masayuki Kitano Masatoshi Kudo | 2010 | World Journal of Radiology2010，2，8： | 40 |

| 3 | Retrospective cohort study Lower incidence of complications in endoscopic nasobiliary drainage for hilar cholangiocarcinoma显示文摘AIM:To identify the most effective endoscopic biliary drainage technique for patients with hilar cholangiocarcinoma.METHODS:In total,118 patients with hilar cholangiocarcinoma underwent endoscopic management[endoscopic nasobiliary drainage(ENBD)or endoscopic biliary stenting]as a temporary drainage in our institution between 2009 and 2014.We retrospectively evaluated all complications from initial endoscopic drainage to surgery or palliative treatment.The risk factors for biliary reintervention,post-endoscopic retrograde cholangiopancreatography(post-ERCP)pancreatitis,and percutaneous transhepatic biliary drainage(PTBD)were also analyzed using patient-and procedure-related characteristics.The risk factors for bilateral drainage were examined in a subgroup analysis of patients who underwent initial unilateral drainage.RESULTS:In total,137 complications were observed in92(78%)patients.Biliary reintervention was required in 83(70%)patients.ENBD was significantly associated with a low risk of biliary reintervention[odds ratio(OR)=0.26,95%CI:0.08-0.76,P=0.012].Post-ERCP pancreatitis was observed in 19(16%)patients.An absence of endoscopic sphincterotomy was significantly associated with post-ERCP pancreatitis(OR=3.46,95%CI:1.19-10.87,P=0.023).PTBD was required in 16(14%)patients,and Bismuth type III or IV cholangiocarcinoma was a significant risk factor(OR=7.88,95%CI:1.33-155.0,P=0.010).Of 102 patients with initial unilateral drainage,49(48%)required bilateral drainage.Endoscopic sphincterotomy(OR=3.24,95%CI:1.27-8.78,P=0.004)and Bismuth II,III,or IV cholangiocarcinoma(OR=34.69,95%CI:4.88-736.7,P<0.001)were significant risk factors for bilateral drainage.CONCLUSION:The endoscopic management of hilar cholangiocarcinoma is challenging.ENBD should be selected as a temporary drainage method because of its low risk of complications. | Kazumichi Kawakubo Hiroshi Kawakami Masaki Kuwatani Shin Haba Taiki Kudo Yoko A Taya Shuhei Kawahata Yoshimasa Kubota Kimitoshi Kubo Kazunori Eto Nobuyuki Ehira Hiroaki Yamato Manabu Onodera Naoya Sakamoto | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，9： | 26 |
| 4 | Endoscopic diagnosis of sessile serrated adenoma/polyp with and without dysplasia/carcinoma显示文摘Sessile serrated adenoma/polyps(SSA/Ps) are early precursor lesions in the serrated neoplasia pathway, which results in colorectal carcinomas with BRAF mutations, methylation for DNA repair genes, a Cp G island methylator phenotype, and high levels of microsatellite instability. Some of these lesions can rapidly become dysplastic or invasive carcinomas that exhibit high lymphatic invasion and lymph node metastasis potentials. Detecting serrated lesions, including SSA/Ps with and without dysplasia/carcinoma, is critical, but SSA/Ps can be difficult to detect, are inconsistently identified by endoscopists and pathologists, and are often incompletely resected. Therefore, SSA/Ps are considered to be major contributors to 'interval cancers'. If colonoscopists can identify the specific endoscopic characteristics of SSA/Ps, their detection and the effectiveness of colonoscopy may improve. Here, the endoscopic features of SSA/Ps with and without dysplasia/carcinoma, including the characteristics determined using magnifying endoscopy, are reviewed in the context of previous reports. Endoscopically, these subtle polyps are like hyperplastic polyps, because they are slightly elevated and pale. Unlike hyperplastic polyps, SSA/Ps are usually larger than 5 mm, frequently covered by a thin layer called the ‘‘mucus cap'', and are more commonly located in the proximal colon. Magnifying narrow-band imaging findings, which include dark spots inside the crypts and varicose microvascular vessels, in addition to the type II-open pit patterns detected using magnifying chromoendoscopy, effectively differentiate SSA/Ps from hyperplastic polyps. The lesions' endoscopic characteristics, which include their(semi)pedunculated morphologies, double elevations, central depressions, and reddishness, and the use of magnifying endoscopy, might help to detect dysplasia/carcinoma within SSA/Ps. Greater awareness may promote further research into improving the detection, identification, and complete resection rates of SSA/Ps with and without dysplasia/carcinoma and reduce the interval cancer rates. | Takashi Murakami Naoto Sakamoto Akihito Nagahara | 2018 | World Journal of Gastroenterology2018，24，29： | 25 |
| 5 | Assessment of the validity of the clinical pathway for colon endoscopic submucosal dissection显示文摘AIM: To determine the effective hospitalization period as the clinical pathway to prepare patients for endoscopic submucosal dissection (ESD). METHODS: This is a retrospective observational study which included 189 patients consecutively treated by ESD at the National Cancer Center Hospital from May 2007 to March 2009. Patients were divided into 2 groups; patients in group A were discharged in 5 d and patients in group B included those who stayed longer than 5 d. The following data were collected for both groups: mean hospitalization period, tumor site, median tumor size, post-ESD rectal bleeding requiring urgent endoscopy, perforation during or after ESD, abdominal pain, fever above 38 ℃, and blood test results positive for inflammatory markers before and after ESD. Each parameter was compared after data collection. RESULTS: A total of 83% (156/189) of all patients could be discharged from the hospital on day 3 postESD. Complications were observed in 12.1% (23/189) of patients. Perforation occurred in 3.7% (7/189) of patients. All the perforations occurred during the ESD procedure and they were managed with endoscopic clipping. The incidence of post-operative bleeding was 2.6% (5/189); all the cases involved rectal bleeding. We divided the subjects into 2 groups: tumor diameter ≥ 4 cm and < 4 cm; there was no significant difference between the 2 groups (P = 0.93, χ 2 test with Yates correction). The incidence of abdominal pain was 3.7% (7/189). All the cases occurred on the day of the procedure or the next day. The median white blood cell count was 6800 ± 2280 (cells/μL; ± SD) for group A, and 7700 ± 2775 (cells/μL; ± SD) for group B, showing a statistically significant difference (P = 0.023, t-test). The mean C-reactive protein values the day after ESD were 0.4 ± 1.3 mg/dL and 0.5 ± 1.3 mg/dL for groups A and B, respectively, with no significant difference between the 2 groups (P = 0.54, t -test). CONCLUSION: One-day admission is sufficient in the absence of complications during ESD or early postoperative bleeding. | Takaya Aoki Takeshi Nakajima Yutaka Saito Takahisa Matsuda Taku Sakamoto Takao Itoi Yassir Khiyar Fuminori Moriyasu | 2012 | World Journal of Gastroenterology2012，18，28： | 22 |
| 6 | Evaluation and treatment of malignant ascites secondary to gastric cancer显示文摘Malignant ascites affects approximately 10% of patients with gastric cancer(gC), and poses significant difficulties for both patients and clinicians. In addition to the dismal general condition of affected patients and the diversity of associated complications such as jaundice and ileus, problems in assessing scattered tumors have hampered the expansion of clinical trials for this condition. However, the accumulation of reported studies is starting to indicate that the weak response to treatment in g C patients with malignant ascites is more relevant to their poor prognosis rather than to the ascites volume at diagnosis. Therefore, precise assessment of initial state of ascites, repetitive evaluation of treatment efficacy, selection of suitable treatment, and swift transition to other treatment options as needed are paramount to maximizing patient benefit. Accurately determining ascites volume is the crucial first step in clinically treating a patient with malignant ascites. Ultrasonography is commonly used to identify the existence of ascites, and several methods have been proposed to estimate ascites volume. Reportedly, the sum of the depth of ascites at five points(named 'five-point method') on three panels of computed tomography images is well correlated to the actual ascites volume and/or abdominal girth. This method is already suited to repetitive assessment due to its convenience compared to the conventional volume rendering method. Meanwhile, a new concept, 'Clinical Benefit Response in g C(CBR-GC)', was recently introduced to measure the efficacy of chemotherapy for malignant ascites of g C. CBR-GC is a simple and reliable patient-oriented evaluation system based on changes in performance status and ascites, and is expected to become an important clinical endpoint in future clinical trials. The principal of treatment for g C patients with ascites is palliation and prevention of ascites-related symptoms. The treatment options are various, including a standard treatment based on the available guidelines, cytoreductive surgery with hyperthermic intraperitoneal chemotherapy(HIPEC), laparoscopic HIPEC alone, intravenous chemotherapy, intraperitoneal chemotherapy, and molecular targetingtherapy. Although each treatment option is valid,further research is imperative to establish the optima choice for each patient. | Hiromichi Maeda Michiya Kobayashi Junichi Sakamoto | 2015 | World Journal of Gastroenterology2015，21，39： | 23 |
| 7 | Long-term survival after resection of pancreatic cancer:A single-center retrospective analysis显示文摘AIM: To retrospectively analyze factors affecting the long-term survival of patients with pancreatic cancer who underwent pancreatic resection.METHODS: From January 2000 to December 2011,195 patients underwent pancreatic resection in our hospital.The prognostic factors after pancreatic resection were analyzed in all 195 patients.After excluding the censored cases within an observational period,the clinicopathological characteristics of 20 patients who survived ≥ 5(n = 20) and < 5(n = 76) years were compared.For this comparison,we analyzed the patients who underwent surgery before June 2008 and were observed for more than 5 years.For statistical analyses,the log-rank test was used to compare the cumulative survival rates,and the χ2 and Mann-Whitney tests were used to compare the two groups.The CoxHazard model was used for a multivariate analysis,and P values less than 0.05 were considered significant.A multivariate analysis was conducted on the factors that were significant in the univariate analysis.RESULTS: The median survival for all patients was 27.1 months,and the 5-year actuarial survival rate was 34.5%.The median observational period was 595 d.With the univariate analysis,the UICC stage was significantly associated with survival time,and the CA19-9 ≤ 200 U/m L,DUPAN-2 ≤ 180 U/m L,t u m o r s i ze ≤ 2 0 m m,R 0 re s e c t i o n,a b s e n c e o f lymph node metastasis,absence of extrapancreatic neural invasion,and absence of portal invasion were favorable prognostic factors.The multivariate analysis showed that tumor size ≤ 20 mm(HR = 0.40; 95%CI: 0.17-0.83,P = 0.012) and negative surgical margins(R0 resection)(HR = 0.48; 95%CI: 0.30-0.77,P = 0.003) were independent favorable prognostic factors.Among the 96 patients,20 patients survived for 5 years or more,and 76 patients died within 5 years after operation.Comparison of the 20 5-year survivors with the 76 non-survivors showed that lower concentrations of DUPAN-2(79.5 vs 312.5 U/mL,P = 0.032),tumor size ≤ 20 mm(35% vs 8%,P = 0.008),R0 resection(95% vs 61%,P = 0.004),and absence of lymph nodemetastases(60% vs 18%,P = 0.036) were significantly associated with the 5-year survival.CONCLUSION: Negative surgical margins and a tumor size ≤ 20 mm were independent favorable prognostic factors.Histologically curative resection and early tumor detection are important factors in achieving long-term survival. | Takehito Yamamoto Shintaro Yagi Hiromitsu Kinoshita Yusuke Sakamoto Kazuyuki Okada Kenji Uryuhara Takeshi Morimoto Satoshi Kaihara Ryo Hosotani | 2015 | World Journal of Gastroenterology2015，21，1： | 18 |
| 8 | 改进的灰色模型在中国能源消费及其CO_2排放预测中的研究(英文)显示文摘中国高速的经济发展导致了快速的能源消费和地球温暖化气体的排放量。本文应用灰色理论建立了中国的终端能源消费量的动态预测模型,同时应用等维递补及带有马尔科夫链符号估计的残差修正,对原始模型进行了改进。后验检验的结果证明了改进的预测模型具有较高的计算精度。预测结果表明,两种经济发展情况(高速及低速)下,从2000年到2030年期间的终端能源消费量的平均增长率将分别达到3.06%和2.18%,2030年CO2 的排放量将分别达到2000年的 2. 15及 1.60倍。其中工业及居民生活的能源消费量的增加速度快于其他部门。这表明了中国将要加快其工业化及都市化的进程.终端消费中,煤炭的消费量所占的比例将要逐年减少,而电力的比例则将逐年增大。 | 穆海林 SAKAMOTO K 董旭辉 王伟 TONOOKA Y 宁亚东 周伟生 | 2002 | 中国沙漠2002，22，2： | 17 |

| 10 | Branched-chain amino acid treatment before transcatheter arterial chemoembolization for hepatocellular carcinoma显示文摘AIM:To examine the significance of branched-chain amino acid (BCAA) treatment before transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC).METHODS:This study included 99 patients who underwent TACE therapy for HCC at our hospital and were followed up without treatment for at least 6 mo between January 2004 and January 2010.They were divided into 2 groups:those receiving BCAA granules (n=40) or regular diet (n=59,control).Data obtained were retrospectively analyzed (prior to TACE,and 1 wk,1,3,and 6 mo after TACE) in terms of nutritional condition and clinical laboratory parameters (serum albumin level and Child-Pugh score),both of which are determinants of hepatic functional reserve.RESULTS:The BCAA group comprised 27 males and 13 females with a mean age of 69.9 ± 8.8 years.The patients of the BCAA group were classified as follows:Child-Pugh A/B/C in 22/15/3 patients,and Stage Ⅱ/Ⅲ /ⅣA HCC in 12/23/5 patients,respectively.The controlgroup comprised 32 males and 27 females with a mean age of 73.2 ± 10.1 years.In the control group,9 patients had chronic hepatitis,Child-Pugh A/B/C in 39/10/1 patients,and StageⅠ/Ⅱ/Ⅲ/ⅣA HCC in 1/11/35/12 patients,respectively.Overall,both serum albumin level and Child-Pugh score improved significantly in the BCAA group as compared with the control 3 and 6 mo after TACE (P < 0.05).Further analysis was performed by the following categorization:(1) child-Pugh classification;(2) liver cirrhosis subgroup with a serum albumin level > 3.5 g/dL;and (3) epirubicin dose.A similar trend indicating a significant improvement of all variables in the BCAA group was noted (P < 0.05).CONCLUSION:Treatment with BCAA granules in patients who have undergone TACE for HCC is considered useful to maintain their hepatic functional reserve. | Hiroki Nishikawa Yukio Osaki Tadashi Inuzuka Haruhiko Takeda Jun Nakajima Fumihiro Matsuda Shinichiro Henmi Azusa Sakamoto Tetsuro Ishikawa Sumio Saito Ryuichi Kita Toru Kimura | 2012 | World Journal of Gastroenterology2012，18，12： | 16 |
| 11 | Controversies regarding and perspectives on clinical utility of biomarkers in hepatocellular carcinoma显示文摘The prevalence of hepatocellular carcinoma(HCC)worldwide parallels that of persistent infection with the hepatitis B virus(HBV)and/or hepatitis C virus(HCV).According to recommendations by the World Health Organization guidelines for HBV/HCV,alpha-fetoprotein(AFP)testing and abdominal ultrasound should be performed in routine surveillance of HCC every 6 mo for high-risk patients.These examinations have also been recommended worldwide by many other HCC guidelines over the past few decades.In recent years,however,the role of AFP in HCC surveillance and diagnosis has diminished due to advances in imaging modalities.AFP was excluded from the surveillance and/or diagnostic criteria in the HCC guidelines published by the American Association for the Study of Liver Diseases in 2010,the European Association for the Study of the Liver in 2012,and the National Comprehensive Cancer Network in 2014.Other biomarkers,including the Lens culinaris agglutinin-reactive fraction of AFP(AFP-L3),des-γ-carboxyprothrombin,Dickkopf-1,midkine,and micro RNA,are being studied in this regard.Furthermore,increasing attention has focused on the clinical utility of biomarkers as pre-treatment predictors for tumor recurrence and as post-treatment monitors.Serum and tissue-based biomarkers and genomics may aid in the diagnosis of HCC,determination of patient prognosis,and selection of appropriate treatment.However,further studies are needed to better characterize the accuracy and potential role of these approaches in clinical practice. | Pei-Pei Song Ju-Feng Xia Yoshinori Inagaki Kiyoshi Hasegawa Yoshihiro Sakamoto Norihiro Kokudo Wei Tang | 2016 | World Journal of Gastroenterology2016，22，1： | 15 |

| 13 | Mercury concentration in hair samples from Chinese people in coastal cities显示文摘This investigation was made to estimate current normal concentrations of total mercury in the hair of Chinese coastal people. Hair samples were collected from 659 healthy inhabitants in the areas along the coast and the rivers (such as Shanghai, Ningbo, Dalian, Xiamen, and Zhoushan) of China from Feb. 2005 to June 2006. Total mercury concentrations in the samples were analyzed by the cold vapor atomic adsorption spectrometry method (CVAAS). The results showed the geometric mean concentration of total mercury in the hair of the total population (N = 659) was 0.83 μg/g, and the geometric mean of the concentrations of total mercury in the hair of the male (0.94 μg/g, 338 inhabitants with an average age of 35.2, age 2-93) was higher than that of the female (0.72 μg/g, 321 inhabitants with an average age of 39.1, age 1-90). In both the male and female, the mean concentrations of total mercury in hair increased with age, and then gradually decreased. There was a significant correlation between the total hair mercury and the place of residence (p < 0.01), and total hair mercury was the highest in volunteers who lived in Zhoushan. Over half of all sample concentrations were below the USEPA-recommended 1 μg/g. In Zhoushan (males, 2.44 μg/g; females, 1.94 μg/g) and Ningbo (males, 1.06 μg/g; females, 1.02 μg/g), it exceeded the recommended level. Very little females (0.3%) of reproductive age showed hair mercury levels close to 10 μg/g. It was thus concluded that fish consumption was a major current route for mercury exposure in China. | SAKAMOTO Mineshi | 2008 | Journal of Environmental Sciences2008，20，10： | 13 |
| 14 | Endoscopic submucosal dissection for colorectal neoplasms:A review显示文摘The introduction of colorectal endoscopic submucosal dissection(ESD)has expanded the application of endoscopic treatment,which can be used for lesions with a low metastatic potential regardless of their size.ESD has the advantage of achieving en bloc resection with a lower local recurrence rate compared with that of piecemeal endoscopic mucosal resection.Moreover,in the past,surgery was indicated in patients with large lesions spreading to almost the entire circumference of the rectum,regardless of the depth of invasion,as endoscopic resection of these lesions was technically difficult.Therefore,a prime benefit of ESD is significant improvement in the quality of life for patients who have large rectal lesions.On the other hand,ESD is not as widely applied in the treatment of colorectal neoplasms as it is in gastric cancers owing to the associated technical difficulty,longer procedural duration,and increased risk of perforation.To diversify the available endoscopic treatment strategies for superficial colorectal neoplasms,endoscopists performing ESD need torecognize its indications,the technical issues involved in its application,and the associated complications.This review outlines the methods and type of devices used for colorectal ESD,and the training required by endoscopists to perform this procedure. | Taku Sakamoto Genki Mori Masayoshi Yamada Yuzuru Kinjo Eriko So Seiichiro Abe Yosuke Otake Takeshi Nakajima Takahisa Matsuda Yutaka Saito | 2014 | World Journal of Gastroenterology2014，20，43： | 13 |
| 15 | Effect of dietary docosahexaenoic acid on lipogenesis and lipolysis in black sea bream,Acanthopagrus schlegeli显示文摘Hatchery-reared juvenile black sea breams are characterized by a low level of highly unsaturated fatty acids in their bodies, as compared with wild fish. To assess the effect of docosahaxaenoic acid (DHA) on lipogenic and lipolysis enzymes, one-year fish were reared on a casein-based purified diet and a DHA fortified diet (1.5% DHA ethyl ester/kg diet) for 60 d, followed with a period of 55 d for starvation. Dietary DHA was effectively incorporated into the fish body. Fortification of DHA depressed activities of glucose-6-phosphate dehydrogenase and NADP-isocitrate dehydrogenase as lipogenic enzymes in the hepatopancreas and intraperitoneal fat body. Carnitine palmitoyltransferase as lipolysis enzyme in the hepatopancreas was active in the DHA fortified fish. Starvation after feeding experiment induced increased carnitine palmitoyltransferase activity in both control and DHA fortified fish and the activity remained higher in the DHA fortified fish, while the monoenes were selectively consumed prior to highly unsaturated fatty acids. These results indicated that dietary DHA depressed lipogenesis and activated lipolysis. | JI Hong OM Ahamd Daud YOSHIMATSU Takao UMINO Testuya NAKAGAWA Heisuke FURUHASHI Makoto SAKAMOTO Shuichi | 2007 | Acta Oceanologica Sinica2007，26，1： | 13 |

| 17 | Condyloma acuminatum of the anal canal,treated with endoscopic submucosal dissection显示文摘Condyloma acuminatum(CA) is a common sexually transmitted disease caused by human papilloma virus infection. Not all individuals develop persistent, progressive disease, but careful follow up is required with moderate-to-severe dysplasia to prevent progression to malignancy. Standard therapies include surgical treatments(trans-anal resection and transanal endoscopic microsurgery) and immunotherapeutic and topical methods(topical imiquimod); however, local recurrence remains a considerable problem. Here, we report a case with superficial CA of the anal canal, treated with endoscopic submucosal dissection(ESD). A 28-year-old man presented with a chief complaint of hematochezia. Digital exam did not detect a tumor. Screening colonoscopy revealed 10-mm long, whitish condyles extending from the anal canal to the lower rectum. The lesion covered almost the whole circumference, and only a small amount of normal mucosa remained. Magnifying endoscopy with narrow band imaging showed brownish hairpin-shaped, coiled capillaries. Although histopathological diagnosis by biopsy revealed CA, accurate histological differentiation between CA, papilloma, and squamous cell carcinoma can be difficult with a small specimen. Therefore, weperformed diagnostic ESD, which provides a complete specimen for precise histopathological evaluation. The pathological diagnosis was CA, with moderate dysplasia(anal intraepithelial neoplasia 2). There was no recurrence at 16 mo after the initial ESD. Compared to surgical treatment, endoscopic diagnosis and resection could be performed simultaneously and the tumor margin observed clearly with a magnifying chromocolonoscopy, resulting in less recurrence. These findings suggest that endoscopic resection may be an alternative method for CA that prevents recurrence. | Akiko Sasaki Takeshi Nakajima Hideto Egashira Kotaro Takeda Shinnosuke Tokoro Chikamasa Ichita Sakue Masuda Haruki Uojima Kazuya Koizumi Takeshi Kinbara Taku Sakamoto Yutaka Saito Makoto Kako | 2016 | World Journal of Gastroenterology2016，22，8： | 11 |
| 18 | Diagnosis of pancreatic tumors by endoscopic ultrasonography显示文摘Pancreatic tumors are highly diverse, as they can be solid or cystic, and benign or malignant. Since their imaging features overlap considerably, it is often difficult to characterize these tumors. In addition, small pancreatic tumors, especially those less than 2 cm in diameter, are difficult to detect and diagnose. For characterizing pancreatic tumors and detecting small pancreatic tumors, endoscopic ultrasonography (EUS) is the most sensitive of the imaging procedures currently available. This technique also provides good results in terms of the preoperative staging of pancreatic tumors. EUS-guided fine needle aspiration (EUS-FNA) has also proved to be a safe and useful method for tissue sampling of pancreatic tumors. Despite these advantages, however, it is still difficult to differentiate between be-nign and malignant, solid or cystic pancreatic tumors, malignant neoplasms, and chronic pancreatitis using EUS, even when EUS-FNA is performed. Recently, contrast-enhanced EUS with Doppler mode (CE-EUS) employing ultrasound contrast agents, which indicate vascularization in pancreatic lesions, has been found to be useful in the differential diagnosis of pancreatic tumors, especially small pancreatic tumors. However, Doppler ultrasonography with contrast-enhancement has several limitations, including blooming artifacts, poor spatial resolution, and low sensitivity to slow flow. Consequently, an echoendoscope was developed recently that has a broad-band transducer and an imaging mode that was designed specifically for contrastenhanced harmonic EUS (CEH-EUS) with a secondgeneration ultrasound contrast agent. The CEH-EUS technique is expected to improve the differential diagnosis of pancreatic disease in the future. This review describes the EUS appearances of common solid and cystic pancreatic masses, the diagnostic accuracy of EUS-FNA, and the relative efficacies and advantages of CE-EUS and CEH-EUS along with their relative advantages and their complementary roles in clinical practice. | Hiroki Sakamoto Masayuki Kitano Ken Kamata Muhammad El-Masry Masatoshi Kudo | 2010 | World Journal of Radiology2010，2，4： | 11 |
| 19 | Current status of preoperative drainage for distal biliary obstruction显示文摘Preoperative biliary drainage(PBD) was developed to improve obstructive jaundice, which affects a number of organs and physiological mechanisms in patients waiting for surgery. However, its role in patients who will undergo pancreaticoduodenectomy for biliary obstruction remains controversial. This article aims to review the current status of the use of preoperative drainage for distal biliary obstruction. Relevant articles published from 1980 to 2015 were identified by searching MEDLINE and Pub Med using the keywords 'PBD', 'pancreaticoduodenectomy', and 'obstructive jaundice'. Additional papers were identified by a manual search of the references from key articles. Current studies have demonstrated that PBD should not be routinely performed because of the postoperative complications. PBD should only be considered in carefully selected patients, particularly in cases where surgery had to be delayed. PBD may be needed in patients with severe jaundice, concomitant cholangitis, or severe malnutrition. The optimal method of biliary drainage has yet to be confirmed. PBD should be performed by endoscopic routes rather than by percutaneous routes to avoid metastatic tumor seeding. Endoscopic stenting or nasobiliary drainage can be selected. Although more expensive, the use of metallic stents remains a viable option to achieve effective drainage without cholangitis and reintervention. | Harutoshi Sugiyama Toshio Tsuyuguchi Yuji Sakai Rintaro Mikata Shin Yasui Yuto Watanabe Dai Sakamoto Masato Nakamura Reina Sasaki Jun-ichi Senoo Yuko Kusakabe Masahiro Hayashi Osamu Yokosuka | 2015 | World Journal of Hepatology2015，7，18： | 11 |
| 20 | Prognostic value of postoperative complication for early recurrence after curative resection of hepatocellular carcinoma显示文摘Background: Postoperative complications may adversely affect oncological outcomes. The aim of this study was to evaluate the impact of postoperative complications on early-phase recurrence after curative resection for hepatocellular carcinoma(HCC).Methods: We included 145 HCC patients who underwent initial and curative resection between January2004 and December 2013. Postoperative complications of grade III or higher based on Clavien–Dindo classification were defined as clinically relevant postoperative complications. Recurrence within two years after hepatectomy was defined as early-phase recurrence.Results: Thirty-eight patients(26%) developed postoperative complications. The only predictive factor for postoperative complication was longer operative duration(P = 0.037). The disease-specific survival rate of patients with complication was lower than that of patients without complications(P = 0.015). Earlyphase recurrence was observed in 20/38(53%) patients who suffered postoperative complications and36/107(34%) patients with no complications, which was statistically significant(P = 0.039). Multivariate analysis identified four factors contributing to early-phase recurrence: high serum AFP level(P = 0.042),multiple tumors(P < 0.001), poor differentiation(P = 0.036) and presence of postoperative complication(P = 0.039).Conclusions: Postoperative complication is an independent prognostic factor for early-phase recurrence after curative resection of HCC. Close observation of patients with postoperative complications may be a necessary treatment strategy for HCC. | Masataka Amisaki Hiroaki Saito Naruo Tokuyasu Teruhisa Sakamoto Soichiro Honjo Yoshiyuki Fujiwara | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，4： | 10 |
