| 1 | Diagnosis of gastrointestinal bleeding: A practical guide for clinicians显示文摘Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians. | Bong Sik Matthew Kim Bob T Li Alexander Engel Jaswinder S Samra Stephen Clarke Ian D Norton Angela E Li | 2014 | World Journal of Gastrointestinal Pathophysiology2014，5，4： | 13 |
| 2 | One hundred and seventy-eight consecutive pancreatoduodenectomies without mortality:role of the multidisciplinary approach显示文摘BACKGROUND:Pancreatoduodenectomy offers the only chance of cure for patients with periampullary cancers.This,however,is a major undertaking in most patients and is associated with a significant morbidity and mortality.A multidisciplinary approach to the workup and follow-up of patients undergoing pancreatoduodenectomy was initiated at our institution to improve the diagnosis,resection rate,mortality and morbidity.We undertook the study to assess the effect of this approach on diagnosis,resection rates and short-term outcomes such as morbidity and mortality.METHODS:A prospective database of patients presenting with periampullary cancers to a single surgeon between April 2004 and April 2010 was reviewed.All cases were discussed at a multidisciplinary meeting comprising surgeons,gastroenterologists,radiologists,oncologists,radiation oncologists,pathologists and nursing staff.A standardized investigation and management algorithm was followed.Complications were graded according to the Clavien-Dindo classification.RESULTS:A total of 295 patients with a periampullary lesion were discussed and 178 underwent pancreatoduodenectomy (resection rate 60%).Sixty-one patients (34%) required either a vascular or an additional organ resection.Eighty-nine patients experienced complications,of which the commonest was blood transfusion (12%).Thirty-four patients (19%) had major complications,i.e.grade 3 or above.There was no in-hospital,30-day or 60-day mortality.CONCLUSIONS:Pancreatoduodenectomy can safely be performed in high-volume centers with very low mortality.The surgeon's role should be careful patient selection,intensive preoperative investigations,use of a team approach,and an unbiased discussion at a multidisciplinary meeting to optimize the outcome in these patients. | Jaswinder S Samra Raul Alvarado Bachmann Julian Choi Anthony Gill Michael Neale Vikram Puttaswamy Cameron Bell Ian Norton Sarah Cho Steven Blome Ritchie Maher Sivakumar Gananadha Thomas J Hugh | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，4： | 8 |
