| 1 | Post-polypectomy bleeding and thromboembolism risks associated with warfarin vs direct oral anticoagulants显示文摘AIM To verify the validity of the endoscopy guidelines for patients taking warfarin or direct oral anticoagulants(DOAC).METHODS We collected data from 218 patients receiving oral anticoagulants(73 DOAC users, 145 warfarin users) and 218 patients not receiving any antithrombotics(age-and sexmatched controls) who underwent polypectomy.(1) We evaluated post-polypectomy bleeding(PPB) risk in patients receiving warfarin or DOAC compared with controls;(2) we assessed the risks of PPB and thromboembolism between three AC management methods: Discontinuing AC with heparin bridge(HPB)(endoscopy guideline recommendation), continuing AC, and discontinuing AC without HPB.RESULTS PPB rate was significantly higher in warfarin users and DOAC users compared with controls(13.7% and 13.7% vs 0.9%, P < 0.001), but was not significantly different between rivaroxaban(13.2%), dabigatran(11.1%), and apixaban(13.3%) users. Two thromboembolic events occurred in warfarin users, but none in DOAC users. Compared with the continuing anticoagulant group, the discontinuing anticoagulant with HPB group(guideline recommendation) had a higher PPB rate(10.8% vs 19.6%, P = 0.087). These findings were significantly evident in warfarin but not DOAC users. One thrombotic event occurred in the discontinuing anticoagulant with HPB group and the discontinuing anticoagulant without HPB group; none occurred in the continuing anticoagulant group.CONCLUSION PPB risk was similar between patients taking warfarin and DOAC. Thromboembolism was observed in warfarin users only. The guideline recommendations for HPB should be re-considered. | Naohiro Yanagisawa Naoyoshi Nagata Kazuhiro Watanabe Tatsuhiro Iida Mariko Hamada Sakurako Kobayashi Takuro Shimbo Junichi Akiyama Naomi Uemura | 2018 | World Journal of Gastroenterology2018，24，14： | 6 |
| 2 | IgG4-unrelated type 1 autoimmune pancreatitis显示文摘A 50-year-old male was referred to our hospital for the evaluation of hyperproteinemia.Fluorodeoxyglucose positron emission tomography revealed high fluorodeoxyglucose uptake in the pancreas,bilateral lacrimal glands,submandibular glands,parotid glands,bilateral pulmonary hilar lymph nodes,and kidneys.Laboratory data showed an elevation of hepatobiliary enzymes,renal dysfunction,and remarkably high immunoglobulin(Ig) G levels,without elevated serum IgG4.Abdominal computed tomography revealed swelling of the pancreatic head and bilateral kidneys.Endoscopic retrograde cholangiopancreatography showed an irregular narrowing of the main pancreatic duct in the pancreatic head and stricture of the lower common bile duct.Histological examination by endoscopic ultrasonography-guided fine-needle aspiration revealed findings of lymphoplasmacytic sclerosing pancreatitis without IgG4-positive plasma cells.Abnormal laboratory values and the swelling of several organs were improved by the treatment with steroids.The patient was diagnosed as having type 1 autoimmune pancreatitis(AIP) based on the International Consensus Diagnostic Criteria.Therefore,we encountered a case of compatible type 1 AIP without elevated levels of serum IgG4 or IgG4-positive plasma cells.This case suggests that AIP phenotypes are not always associated with IgG4. | Eriko Nakano Atsushi Kanno Atsushi Masamune Naoki Yoshida Seiji Hongo Shin Miura Tetsuya Takikawa Shin Hamada Kiyoshi Kume Kazuhiro Kikuta Morihisa Hirota Keisuke Nakayama Fumiyoshi Fujishima Tooru Shimosegawa | 2015 | World Journal of Gastroenterology2015，21，33： | 3 |
| 3 | Pancreatic duct drainage using EUS-guided rendezvous technique for stenotic pancreaticojejunostomy显示文摘The patient was a 30-year-old female who had undergone excision of the extrahepatic bile duct and Rouxen-Y hepaticojejunostomy for congenital biliary dilatation at the age of 7.Thereafter,she suffered from recurrent acute pancreatitis due to pancreaticobiliary maljunction and received subtotal stomach-preserving pancreaticoduodenectomy.She developed a pancreatic fistula and an intra-abdominal abscess after the operation.These complications were improved by percutaneous abscess drainage and antibiotic therapy.How ever,upper abdominal discomfort and the elevation of serum pancreatic enzymes persisted due to stenosis from the pancreaticojejunostomy.Because we could not accomplish dilation of the stenosis by endoscopic retrograde cholangiopancreatography,we tried an endoscopic ultrasonography(EUS) guided rendezvous technique for pancreatic duct drainage.After transgastric puncture of the pancreatic duct using an EUS-fine needle aspiration needle,the guidewire was inserted into the pancreatic duct and finally reached to the jejunum through the stenotic anastomosis.We changed the echoendoscope to an oblique-viewing endoscope,then grasped the guidewire and withdrew it through the scope.The stenosis of the pancreaticojejunostomy was dilated up to 4 mm,and a pancreatic stent was put in place.Though the pancreatic stent was removed after three months,the patient remained symptomfree.Pancreatic duct drainage using an EUS-guided rendezvous technique was useful for the treatment of a stenotic pancreaticojejunostomy after pancreaticoduodenectomy. | Tetsuya Takikawa Atsushi Kanno Atsushi Masamune Shin Hamada Eriko Nakano Shin Miura Hiroyuki Ariga Jun Unno Kiyoshi Kume Kazuhiro Kikuta Morihisa Hirota Hiroshi Yoshida Yu Katayose Michiaki Unno Tooru Shimosegawa | 2013 | World Journal of Gastroenterology2013，19，31： | 3 |

| 16 | Anchor-wire technique for multiple plastic biliary stents to prevent stent dislocation显示文摘In endoscopic placement of multiple plastic biliary stents (PBSs),we sometimes experience proximal dislocation of the first PBS at the time of subsequent PBS insertion.We describe the case of a 79-year-old male with obstructive jaundice caused by cholangiocarcinoma who needed to receive multiple PBS placements for management of cholangitis.Although proximal dislocation of the first PBS was observed,we prevented the dislocation via our technique of using guidewire inserted from the distal end of the first PBS to the side hole as the anchor-wire.We could complete this technique only by inserting guidewire through the side hole of the first PBS during the process of releasing the first PBS and pulling out the guidewire and the inner sheath.It did not matter whether the anchor-wire went towards the third portion of the duodenum or the duodenal bulb.Here we introduce this 'anchor-wire technique',which is useful for the prevention of PBS proximal dislocation in placing multiple PBSs. | Tsuyoshi Hamada Yousuke Nakai Saburo Matsubara Hiroyuki Isayama Akiko Narita Kazuhiro Watanabe Yukihiro Koike Shigeo Matsukawa Tateo Kawase Kazuhiko Koike | 2011 | World Journal of Gastroenterology2011，17，28： | 0 |
