Background To evaluate roles of intraoperative endoscopy (IOE) in management of severe obscure GI bleeding (OGIB) before vs. after introduction of video capsule endoscopy (VCE) and deep enteroscopy (DE). Methods We retrospectively reviewed prospectiv

Publikováno v: Digestive diseases and sciences, vol 61, iss 9

BackgroundThe sites of origin, causes and outcomes of severe hematochezia have not been compared between cirrhotics and non-cirrhotics. In cirrhotics versus non-cirrhotics presenting with severe hematochezia, we aimed at (1) identifying the site and

Publikováno v: Journal of clinical gastroenterology, vol 50, iss 1

BACKGROUND AND AIMS Improved medical decisions by using a score at the initial patient triage level may lead to improvements in patient management, outcomes, and resource utilization. There is no validated score for management of lower gastrointestin

The term “lower gastrointestinal (LGI) bleeding” usually refers to a bleeding site starting below the ligament of Treitz (Jensen and Machicado 1988). “Hematochezia” is the clinical term applied to the passage of bright red blood or maroon col

Doppler Endoscopic Probe Monitoring of Blood Flow Improves Risk Stratification and Outcomes of Patients With Severe Nonvariceal Upper Gastrointestinal Hemorrhage

Autor: Gordon V. Ohning, Rome Jutabha, Dennis M. Jensen, Alireza Sedarat, Gareth S. Dulai, Kevin A. Ghassemi, Thomas O. Kovacs, Jeffrey Gornbein, Gustavo A. Machicado

Publikováno v: Gastroenterology, vol 152, iss 6

Background & aimsFor 4 decades, stigmata of recent hemorrhage in patients with nonvariceal lesions have been used for risk stratification and endoscopic hemostasis. The arterial blood flow that underlies the stigmata rarely is monitored, but can be u

Publikováno v: Endoscopy. 45:397-400

We report a case series of all consecutive patients hospitalized in our two tertiary referral medical centers over the past 17 years for Cameron ulcers causing severe upper gastrointestinal hemorrhage (GIH) or severe obscure GIH. Cameron ulcers were

Publikováno v: Gastrointestinal Endoscopy. 74:852-857

Background Risk factors and outcomes of severe hematochezia from ischemic colitis compared with other colonic diagnoses have not been well studied. Objective Our purposes were (1) to compare demographics and outcomes of patients hospitalized with sev

Natural history of definitive diverticular hemorrhage based on stigmata of recent hemorrhage and colonoscopic Doppler blood flow monitoring for risk stratification and definitive hemostasis

Autor: Gustavo A. Machicado, Kevin A. Ghassemi, Rome Jutabha, Gareth S. Dulai, Dennis M. Jensen, Gordon V. Ohning, Thomas O. Kovacs

Publikováno v: Gastrointestinal endoscopy, vol 83, iss 2

Background and Aims Few prospective reports describe the short-term natural history of colon diverticular hemorrhage based on stigmata of recent hemorrhage, and none include blood flow detection for risk stratification or as a guide to definitive hem

Publikováno v: Gastrointestinal endoscopy. 83(1)

For more than 4 decades endoscopists have relied on ulcer stigmata for risk stratification and as a guide to hemostasis. None used arterial blood flow underneath stigmata to predict outcomes. For patients with severe peptic ulcer bleeding (PUB), we u
