| 1 | Endoscopic diagnosis of pancreaticobiliary maljunction显示文摘Pancreaticobiliary maljunction (PBM) is a congenital anomaly defined as a junction of the pancreatic and bile ducts located outside the duodenal wall, usually forming a markedly long common channel. As the action of the sphincter of Oddi does not functionally affect the junction in PBM patients, continuous pancreatobiliary reflux occurs, resulting in a high incidence of biliary cancer. PBM can be divided into PBM with biliary dilatation (congenital choledochal cyst) and PBM without biliary dilatation (maximal diameter of the bile duct ≤ 10 mm). The treatment of choice for PBM is prophylactic surgery before malignant changes can take place. Endoscopic retrograde cholangiopancreatography (ERC P) is the most effective examination method for close obs ervation of the pattern of the junction site. When the communication between the pancreatic and bile ducts is maintained, despite contraction of the sphi ncter on ERCP, PBM is diagnosed. In these pat ients, levels of pancreatic enzymes in the bile are gene rally elevated, due to continuous pancreatobiliary reflux via a long common channel. Magnetic resonance cholangiopancreatography and 3D-computed tomography can diagnose PBM, based on findings of an anomalous union between the common bile duct and the pancreatic duct, in addition to a long common channel. Endoscopic ultrasonography and intraductal ultra sonography can demonstrate the junction outside the duodenal wall, and are useful for the diagnosis of asso ciated biliary cancer. Gallbladder wall thickness on ultra so nography can be a screening test for PBM. | Terumi Kamisawa Kensuke Takuma Fumihide Itokawa Takao Itoi | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，1： | 25 |
| 2 | Endoscopic ultrasound-guided choledochoduodenostomy in patients with failed endoscopic retrograde cholangiopancreatography显示文摘Endoscopic ultrasonography (EUS)-guided biliary drainage was performed for treatment of patients who have obstructive jaundice in cases of failed endoscopic retrograde cholangiopancreatography (ERCP). In the present study,we introduced the feasibility and outcome of EUS-guided choledochoduodenostomy in four patients who failed in ERCP. We performed the procedure in 2 papilla of Vater,including one resectable case,and 2 cases of cancer of the head of pancreas. Using a curved linear array echoendoscope,a 19 G needle or a needle knife was punctured transduodenally into the bile duct under EUS visualization. Using a biliary catheter for dilation,or papillary balloon dilator,a 7-Fr plastic stent was inserted through the choledochoduodenostomy site into the extrahepatic bile duct. In 3 (75%) of 4 cases,an indwelling plastic stent was placed,and in one case in which the stent could not be advanced into the bile duct,a naso-biliary drainage tube was placed instead. In all cases,the obstructive jaundice rapidly improved after the procedure. Focal peritonitis and bleeding not requiring blood transfusion was seen in one case. In this case,pancreatoduodenectomy was performed and the surgical findings revealed severe adhesion around the choledochoduodenostomy site. Although further studies and development of devices are mandatory,EUS-guided choledochoduodenostomy appears to be an effective alternative to ERCP in selected cases. | Takao Itoi Fumihide Itokawa Atsushi Sofuni Toshio Kurihara Takayoshi Tsuchiya Kentaro Ishii Shujiro Tsuji Nobuhito Ikeuchi Fuminori Moriyasu | 2008 | World Journal of Gastroenterology2008，14，39： | 13 |
| 3 | Safety trial of high-intensity focused ultrasound therapy for pancreatic cancer显示文摘AIM:To evaluate the safety and clinical application of high-intensity focused ultrasound(HIFU)therapy for unresectable pancreatic cancer(PC).METHODS:Thirty PC patients(16 cases in stage III and 14 cases in stage IV)with visualized pancreatic tumors were admitted for HIFU therapy as an optional local therapy in addition to systemic chemotherapy or chemoradiotherapy.Informed consent was obtained.This study began at the end of 2008 and was approved by the ethics committee of our hospital[Institutional Review Board(IRB):890].The HIFU device used was the FEP-BY02(Yuande Bio-Medical Engineering,Beijing,China).RESULTS:The mean tumor size after HIFU therapy changed to 30.9±1.7 mm from 31.7±1.7 mm at pre-therapy.There were no significant changes in tumor size,mean number of treatment sessions(2.7±0.1 mm),or mean total treatment time(2.4±0.1 h).The rate of symptom relief effect was 66.7%.The effectiveness of primary lesion treatment was as follows:complete response,0;partial response,4;stable disease,22;progressive disease,4.Treatment after HIFU therapy included 2 operations,24 chemotherapy treatments,and 4 best supportive care treatments.Adverse events occurred in 10%of cases,namely pseudocyst formation in 2 cases and mild pancreatitis development in 1.However,no severe adverse events occurred in this study.CONCLUSION:We suggest that HIFU therapy is safe and has the potential to be a new method of combination therapy for PC. | Atsushi Sofuni Fuminori Moriyasu Takatomo Sano Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Kentaro Ishii Syujiro Tsuji Nobuhito Ikeuchi Reina Tanaka Junko Umeda Ryosuke Tonozuka Mitsuyoshi Honjo Shuntaro Mukai Mitsuru Fujita Takao Itoi | 2014 | World Journal of Gastroenterology2014，20，28： | 12 |
| 4 | Endoscopic approach for diagnosing autoimmune pancreatitis显示文摘It is of utmost importance to differentiate autoimmune pancreatitis(AIP) from pancreatic cancer(PC).Segmental AIP cases are sometimes difficult to differentiate from PC.On endoscopic retrograde cholangio pancreatography,long or skipped irregular narrowing of the main pancreatic duct(MPD),less upstream dilatation of the distal MPD,side branches derived from the narrowed portion of the MPD,absence of obstruction of the MPD,and stenosis of the intrahepatic bile duct suggest AIP rather than PC.Abundant infiltration of IgG4-positive plasma cells is frequently and rather specifically detected in the major duodenal papilla of AIP patients.IgG4-immunostaining of biopsy specimens obtained from the major duodenal papilla is useful for supporting a diagnosis of AIP with pancreatic head involvement.On endoscopic ultrasonography(EUS),hyperechoic spots in the hypoechoic mass and the duct-penetrating sign suggest AIP rather than PC.EUS and intraductal ultrasonography sometimes show wall thickening of the common bile duct even in the segment in which abnormalities are not clearly observed with cholangiography in AIP patients.EUS-guided fine needle aspiration,especially EUS-guided Tru-Cut biopsy,is useful to diagnose AIP,as well as to exclude PC. | Terumi Kamisawa Hajime Anjiki Kensuku Takuma Naoto Egawa Takao Itoi Fumihide Itokawa | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，1： | 6 |
| 5 | Endoscopic resection of carcinoid of the minor duodenalpapilla显示文摘We encountered a 65-year-old man with a carcinoid tumor of the minor duodenal papilla. Since he had liver cirrhosis and completely refused surgery, we performed an endoscopic snare papillectomy. The papillectomy was performed successfully without procedure-related complication. The specimens revealed a carcinoid tumor showing that the margin of the tumor was positive. One week later, upper GI endoscopy was performed and the biopsy specimens obtained from base of ulcer showed no neoplastic cells. We performed a duodenoscopy and CT 3, 6 and 18 mo later, and there was no macroscopic or microscopic evidence of tumor recurrence after more than 4 years. | Takao Itoi Atsushi Sofuni Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Fuminori Moriyasu | 2007 | World Journal of Gastroenterology2007，13，27： | 6 |

| 7 | Prognosis of cancer with branch duct type IPMN of the pancreas显示文摘AIM:To examine the coexistence of metachronous and synchronous cancer in branch duct intraductal papillary mucinous neoplasms of the pancreas (IPMN).METHODS: We reviewed the records of 145 patients with branch duct IPMN between January 1991 and April 2008 and assessed the relationship between IPMN and intraor extra-pancreatic carcinoma and the outcome of IPMN.RESULTS: The mean observation period was 55.9 ± 45.3 mo. Among the 145 patients, the frequency of extra-pancreatic cancer was 29.0%. The frequency of gastric cancer, colon cancer, breast cancer, and pan-creatic cancer were 25.5%, 15.7%, 13.7%, and 9.8%, respectively. Twenty (13.8%) of the patients died. The cause of death was extra-pancreatic carcinoma in 40%,pancreatic cancer in 25%, IPMN per se in 20%, and benign disease in 15% of the patients.CONCLUSION: The prognosis for IPMN depends not on the IPMN per se, but on the presence of intraor extra-pancreatic cancer. | Nobuhito Ikeuchi Takao Itoi Atsushi Sofuni Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Kentaro Ishii Shujiro Tsuji Junko Umeda Fuminori Moriyasu Akihiko Tsuchida Kazuhiko Kasuya | 2010 | World Journal of Gastroenterology2010，16，15： | 3 |
| 8 | Usefulness of contrast-enhanced ultrasonography in determining treatment efficacy and outcome after pancreatic cancer chemotherapy显示文摘AIM:To investigate if contrast-enhanced ultrasonography(CE-US) is useful for determining treatment efficacy and outcome in the early stages of pancreatic cancer chemotherapy by assessing changes in intratumor hemodynamics using CE-US with a contrast agent.METHODS:The subjects were 34 patients with unresectable advanced pancreatic cancer treated by chemotherapy.CE-US was assessed after every treatment(course) completion under the same conditions,and patients were divided into two groups according to the intratumor enhancement pattern:Vascular rich(R) group and vascular poor(P) group.RESULTS:After the second course of treatment,R group in intratumor hemodynamics had 18 patients,and P group had 16 patients.The reduction rates of serum CA19-9 level after chemotherapy which decreased to half or less of the baseline level were 2/15(0.1%) in P group,but 11/16(69%) in R group(P = 0.006).When the mean number of courses of chemotherapy and outcome were compared,P group had a mean number of courses of 4.9(R group,10.2) and mean survival time(MST) of 246 d(R group,402 d),showing that outcome was significantly better in R group(P=0.006).CONCLUSION:CE-US revealed that the change in intratumor blood flow correlated with both serum CA19-9 level and outcome.Patients with serum CA19-9 that decreased to less than half the baseline level,and patients with an abundant intratumor blood flow,had a significantly better outcome.Thus,CE-US is potentially useful for evaluating treatment efficacy and outcome in the early stages of pancreatic cancer chemotherapy. | Atsushi Sofuni Takao Itoi Fumihide Itokawa Takayoshi Tsuchiya Toshio Kurihara Kentaro Ishii Syujiro Tsuji Nobuhito Ikeuchi Fuminori Moriyasu | 2008 | World Journal of Gastroenterology2008，14，47： | 3 |
| 9 | 甲酸光催化降解过程中的过氧化氢生成机制显示文摘考察了在3种紫外光源(黑光灯、杀菌灯、臭氧灯)的照射下,分别以TiO2与Pd/TiO2为催化剂,甲酸降解过程中过氧化氢的生成机制.研究发现,在黑光灯/催化剂条件下,可在纯水中生成过氧化氢,但当催化剂缺失时几乎不能生成.在黑光灯或杀菌灯照射下,甲酸溶液在有催化剂存在时可被稳定分解,但当催化剂不存在时则分解非常缓慢.对各种光源而言,Pd/TiO2比TiO2催化降解甲酸的效果好.对光源条件的比较发现,甲酸分解速度与过氧化氢生成速度依次为臭氧灯>杀菌灯>黑光灯.结果表明,甲酸光催化分解初速度与过氧化氢生成的初速度呈正比,过氧化氢生成是光催化降解有机物的关键因素. | 华兆哲 陈坚 Shiraishi Fumihide Nakasako Tsugunori 王歆鹏 | 2006 | 化工学报2006，57，7： | 3 |
