| 1 | Partial stent-in-stent placement of biliary metallic stents using a short double-balloon enteroscopy显示文摘Endoscopic intervention is less invasive than percutaneous or surgical approaches and should be considered the primary drainage procedure in most cases with obstructive jaundice.Recently,therapeutic endoscopic retrograde cholangiopancreatography(ERCP) using double-balloon enteroscopy(DBE) has been shown to be feasible and effective,even in patients with surgically altered anatomies.On the other hand,endoscopic partial stent-in-stent(PSIS) placement of selfexpandable metallic stents(SEMSs) for malignant hilar biliary obstruction in conventional ERCP has also been shown to be feasible,safe and effective.We performed PSIS placement of SEMSs for malignant hilar biliary obstruction due to liver metastasis using a short DBE in a patient with Roux-en-Y anastomosis and achieved technical and clinical success.This procedure can result in quick relief from obstructive jaundice in a single session and with short-term hospitalization,even in patients with surgically altered anatomies. | Koichiro Tsutsumi Hironari Kato Takeshi Tomoda Kazuyuki Matsumoto Ichiro Sakakihara Naoki Yamamoto Yasuhiro Noma Takayuki Sonoyama Hiroyuki Okada Kazuhide Yamamoto | 2012 | World Journal of Gastroenterology2012，18，45： | 3 |
| 2 | Successful biliary drainage using a metal stent through the gastric stoma显示文摘We report a case of biliary drainage for malignant stricture using a metal stent with an ultrathin endoscope through the gastric stoma. A 78-year-old female was referred to our hospital for jaundice and fever. She had undergone percutaneous endoscopic gastrostomy(PEG) for esophageal obstruction after radiation therapy for cancer of the pharynx. Abdominal contrast-enhanced computed tomography showed a 3-cm enhanced mass in the middle bile duct and dilatation of the intrahepatic bile duct. We initially performed endoscopic retrograde cholangiopancreatography(ERCP) with a trans-oral approach. However, neither the side-viewing endoscope nor the ultrathin endoscope passed through the esophageal orifice. Thus, we eventually performed ERCP via the PEG stoma using an ultrathin endoscope. We performed biliary drainage with a 6F introducer selfexpanding metal stent. The cytology findings obtained by brush cytology showed malignancy. Her laboratory results were restored to normal levels after drainage and no complication occurred. | Kazuyuki Matsumoto Hironari Kato Koichiro Tsutsumi Yutaka Akimoto Daisuke Uchida Takeshi Tomoda Naoki Yamamoto Yasuhiro Noma Shigeru Horiguchi Hiroyuki Okada Kazuhide Yamamoto | 2015 | World Journal of Gastroenterology2015，21，24： | 2 |

| 6 | Dilation of a severe bilioenteric or pancreatoenteric anastomotic stricture using a Soehendra Stent Retriever显示文摘Bilioenteric or pancreatoenteric anastomotic stric-tures often occur after surgery for a pancreaticobiliary disorder. Therapeutic endoscopic retrograde cholan-giopancreatography using balloon enteroscopy has been shown to be feasible and effective in patients with such strictures. However, when a benign anas-tomotic stricture is severe, a dilation catheter cannot pass through the stricture despite successful insertion of the guidewire. We report on the usefulness of the Soehendra Stent Retriever over a guidewire for dilating a severe bilioenteric or pancreatoenteric anastomotic stricture under short double-balloon enteroscopy, in two patients with surgically altered anatomies. | Koichiro Tsutsumi Hironari Kato Ichiro Sakakihara Naoki Yamamoto Yasuhiro Noma Shigeru Horiguchi Ryo Harada Hiroyuki Okada Kazuhide Yamamoto | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，8： | 1 |
