| 1 | Endoscopic papillary large balloon dilation for removal of bile duct stones显示文摘AIM:To investigate the efficacy and outcomes of endoscopic papillary large balloon dilation(EPLBD)for bile duct stones in a multicenter prospective study.METHODS:Lithotomy by EPLBD was conducted in 124patients with bile duct stones≥13 mm in size or with three or more bile duct stones≥10 mm.After endoscopic sphincterotomy,the papilla was dilated using balloons 12-20 mm in diameter fitting the bile duct diameter.RESULTS:The success rate of first-time lithotomy was 86.3%(107/124)and the final lithotomy success rate was 100%(124/124).Lithotripsy was needed in10 of the 124(13.6%)patients.Adverse events due to the treatment procedure occurred in 6(4.8%)patients,all of which were mild.Performing large balloon dilation after endoscopic sphincterotomy in patients with large stones or multiple stones in the bile duct is considered to ensure the safety of treatment and to reduce the need for lithotripsy.CONCLUSION:It is suggested that treatment by EPLBD for large bile duct stones may be safe and useful. | Yuji Sakai Toshio Tsuyuguchi Yoshiaki Kawaguchi Nobuto Hirata So Nakaji Katsuya Kitamura Shigeru Mikami Tatsuya Fujimoto Masashi Ijima Eishin Kurihara Shuhei Oana Takayoshi Nishino Ryo Tamura Dai Sakamoto Masato Nakamura Takao Nishikawa Harutoshi Sugiyama Hitoshi Yoshida Tetsuya Mine Osamu Yokosuka | 2014 | World Journal of Gastroenterology2014，20，45： | 6 |
| 2 | Granular cell tumor of the common bile duct: A Japanese case显示文摘Granular cell tumor (GCT) of the biliary system is rare. It is reported that it occurs more commonly in young black women. We report here our seldom experience of a Japanese case in whom icterus was found as a first symptom just after a caesarean operation. A 36-year-old Japanese woman developed icterus after delivery by the Caesarean operation. A surgical operation was performed without can deny that there was a tumor-related change in a bile duct as a result of examination for various images. As a result of pathological evaluation, GCT was diagnosed. By the preoperative organization biomicroscopy result, it was not able to be attachd a right diagnosis. It was thought that this tumor, although rare, should be considered as one of the causes of biliary stenosis in the younger population. | Junko Saito Michiko Kitagawa Hiroshi Kusanagi Nobuyasu Kano Eiji Ishii So Nakaji Nobuto Hirata Kazuei Hoshi | 2012 | World Journal of Gastroenterology2012，18，43： | 2 |

| 4 | Endoscopic lithotripsy with peroral direct cholangioscopy using a conventional endoscope显示文摘Recently,peroral direct cholangioscopy(PDCS) using an ultra-slim endoscope has come into the spotlight.However,the working channel is too small to use various devices for lithotripsy.We report a case of endoscopic lithotripsy with PDCS using a conventional endoscope as a cholangioscope.Computed tomography scan on an 80-year-old female who was admitted with acute cholangitis showed two large stones in the bile duct.Endoscopic retrograde cholangiopancreatography was attempted first.However,mechanical lithotripsy failed because the stone was too large for the basket catheter.Finally,electric hydraulic lithotripsy with PDCS using a conventional endoscope was performed allowed the stones to be cleared completely.In conclusion,PDCS using a conventional endoscope can be an alternative solution for endoscopic lithotripsy for patients with large stones in the dilated bile duct. | So Nakaji Nobuto Hirata Toshiyasu Shiratori Masayoshi Kobayashi Masami Inase | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，3： | 2 |
| 5 | Clinical utility of 0.025-inch guidewire VisiGlide2TM in the endoscopic retrograde cholangiopancreatography-related procedures显示文摘AIM To examine the result of the use of 0.025-inch guidewire(GW) Visi Glide2 TM as the first choice in the endoscopic retrograde cholangiopancreatography(ERCP)-related procedures without selecting the patient in a multicenter prospective study. METHODS ERCP using 0.025-inch GW VisiGlide2^(TM) as the first choice was conducted in patients who have needed ERCP, and its accomplishment rate of procedure, procedural time, incidence of accidental symptoms were compared with those of ERCP using 0.025-inch GW VisiG lideTM.RESULTS The accomplishment rate of procedure was 97.5%(197/202), and procedural time was 23.930 ± 16.207 min. The accomplishment rate of procedure using 0.025-inch GW Visi GlideTM was 92.3%(183/195), and procedural time was 31.285 ± 19.122 min, thus the accomplishment rate of procedure was significantly improved and procedural time was significantly shortened(P < 0.05). Accidental symptoms by ERCPrelated procedures were observed in 3.0%(6/202), and all were conservatively alleviated. CONCLUSION When 0.025-inch GW VisiG lide2 TM was used for ERCPrelated procedure as the first choice, it showed high accomplishment rate of procedure and low incidence of accidental symptoms, suggesting it can be used as the universal GW.

| 6 | Gastrointestinal stromal tumor of the ampulla of Vater:A case report显示文摘Gastrointestinal stromal tumors(GISTs)usually develop in the stomach and small intestine and only rarely occur at the ampulla of Vater,with only 11 cases reported in the literature.We report a case of a GIST of the ampulla of Vater.A 36-year-old,previously healthy man presented with a loss of consciousness lasting a few minutes.A gastroduodenal endoscopy revealed a submucosal tumor with central ulceration at the ampulla of Vater.The enhanced computed tomography scan revealed a smooth-outlined hypervascular solid mass(24 mm×30 mm)in the second part of the duodenum.Neither lymphadenopathy nor metastasis was observed.Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography showed normal bile and pancreatic ducts.Biopsies were collected from the ulcerative lesion,and the tumor was diagnosed as a GIST.A submucosal tumor with central ulceration may be a characteristic form of GISTs of the ampulla of Vater,and biopsy studies are useful for the diagnosing such tumors.The patient underwent pancreatoduodenectomy,and the operative specimen revealed a 2.2-cm GIST with 1 mitosis per 50 highpower fields.The gold standard for treatment of GISTs is surgical resection without rupture of a capsule.If technically possible,local resection may be considered.However,when the location of the lesion presents challenges,a pancreatoduodenectomy should be performed for GIST of the ampulla of Vater. | Masayoshi Kobayashi Nobuto Hirata So Nakaji Toshiyasu Shiratori Hiroyuki Fujii Eiji Ishii | 2014 | World Journal of Gastroenterology2014，20，16： | 1 |
