1A typical presentation of a rare cause of obscure gastrointestinal bleeding显示文摘A 52-year-old white woman had suffered from intermittent gastrointestinal (GI) bleeding for one year. Upper GI endoscopy, colonoscopy and peroral doubleballoon enteroscopy (DBE) did not detect any bleeding sour ce, suggesting obscure GI bleeding. However, in video capsule endoscopy a jejunal ulceration without blee ding signs was suspected and this was endoscopically conf irmed by another peroral DBE. After transfusion of packed red blood cells, the patient was discharged from our hospital in good general condition.Two weeks later she was readmitted because of another episode of acute bleeding. Multi-detector row computed tomography with 3D reconstruction was performed revealing a jejunal tumor causing lower gastrointestinal bleeding. The patient underwent exploratory laparotomy with partial jejunal resection and end-to-end jejunostomy for reconstruction. Histological examination of the specimen confirmed the diagnosis of a low risk gastrointestinal stromal tumor (GIST). Nine days after surgery the patient was discharged in good health. No signs of gastrointestinal rebleeding occurred in a followup of eight months. We herein describe the comp lex presentation and course of this patient with GIST and also review the current approach to treatm ent.Stefan Reuter Dominik Bettenworth Sren Torge Mees Jrg Neumann Torsten Beyna Wolfram Domschke Johannes Wessling Hansjrg Ullerich 2011World Journal of Gastrointestinal Endoscopy2011,3,2:0
2Solid-pseudopapillary pancreatic tumor,mimicking submucosal tumor of the stomach:A case report显示文摘Solid-pseudopapillary tumors of the pancreas(SPTs) are comparatively rare and have low malignancy,with a predilection for young women.Diagnosis is difficult when a SPT develops in a boundary region with other organs.Here,we report a 42-year old woman with a SPT of the pancreas mimicking a submucosal tumor of the stomach on imaging.She was admitted to our hospital complaining of abdominal pain.We suspected a submucosal tumor of the stomach from the f indings of endoscopy,endoscopic ultrasonography and abdominal computed tomography.However,angiography showed that some of the tumor vessels arose from the pancreas.Intraoperative f indings revealed the tumor originated from the pancreas.Therefore,distal pancreatectomy was performed.The pathological diagnosis was SPT of the pancreas.Satoshi Furuhashi Hiroshi Takamori Shinnya Abe Osamu Nakahara Hiroshi Tanaka Kei Horino Toru Beppu Ken-ichi Iyama Hideo Baba 2011World Journal of Gastrointestinal Surgery2011,3,12:0
