  • Chapter 156: Upper Gastrointestinal Bleeding
    8/23/2018 Principles and Practice of Hospital Medicine, 2e > Chapter 156: Upper Gastrointestinal Bleeding Stephen R. Rotman; John R. Saltzman INTRODUCTION Key Clinical Questions What is the timing and treatment of peptic ulcer disease? What are the factors in diagnosis and treatment of aortoenteric fistula? What treatments are available for each etiology of upper GI bleeding? What is the appropriate management and follow-up of variceal bleeding? How do you estimate the severity of bleeding so that you can triage appropriate patients to the ICU, medical floor, or observation unit? Which patients are more likely to rebleed and hence require continued observation in the hospital aer their bleeding has apparently stopped, and for how long? Upper gastrointestinal (GI) bleeding is responsible for over 300,000 hospitalizations per year in the United States. An additional 100,000 to 150,000 patients develop upper GI bleeding during hospitalizations. The annual cost of treating nonvariceal acute upper GI bleeding in the United States exceeds $7 billion. Upper GI bleeding is defined as a bleeding source in the GI tract proximal to the ligament of Treitz. The presentation varies depending on the nature and severity of bleeding and includes hematemesis, melena, hematochezia (in rapid upper GI bleeding), and anemia with heme-positive stools. Bleeding can be associated with changes in vital signs, including tachycardia and hypotension including orthostatic hypotension. Given the range of presentations, pinpointing the nature and severity of GI bleeding may be a challenging task. The natural history of nonvariceal upper GI bleeding is that 80% of patients will stop bleeding spontaneously and no further urgent intervention will be needed.

Gastroenterology, Shimane University Hospital, Izumo, JPN Corresponding author: Kyoichi Adachi, [email protected] Abstract Background This study was performed to examine the prevalence of asymptomatic angiodysplasia detected in upper gastrointestinal endoscopic examinations and of hereditary hemorrhagic telangiectasia (HHT) suspected cases. Methodology The study participants were 5,034 individuals (3,206 males, 1,828 females; mean age 53.5 ± 9.8 years) who underwent an upper gastrointestinal endoscopic examination as part of a medical check-up. The presence of angiodysplasia was examined endoscopically from the pharynx to duodenal second portion. HHT suspected cases were diagnosed based on the presence of both upper gastrointestinal angiodysplasia and recurrent nasal bleeding episodes occurring in the subject as well as a first-degree relative. Results Angiodysplasia was endoscopically detected in 494 (9.8%) of the 5,061 subjects. Those with angiodysplasia lesions in the pharynx, larynx, esophagus, stomach, and duodenum numbered 44, 4, 155, 322, and 12, respectively. None had symptoms of upper gastrointestinal bleeding or severe anemia. Subjects with angiodysplasia showed significant male predominance and were significantly older than those without. A total of 11 (0.2%) were diagnosed as HHT suspected cases by the presence of upper gastrointestinal angiodysplasia and recurrent epistaxis episodes from childhood in the subject as well as a first-degree relative.

  • Obscure Gastrointestinal Bleeding in Cirrhosis: Work-Up and Management
    Current Hepatology Reports (2019) 18:81–86 https://doi.org/10.1007/s11901-019-00452-6 MANAGEMENT OF CIRRHOTIC PATIENT (A CARDENAS AND P TANDON, SECTION EDITORS) Obscure Gastrointestinal Bleeding in Cirrhosis: Work-up and Management Sergio Zepeda-Gómez1 & Brendan Halloran1 Published online: 12 February 2019 # Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract Purpose of Review Obscure gastrointestinal bleeding (OGIB) in patients with cirrhosis can be a diagnostic and therapeutic challenge. Recent advances in the approach and management of this group of patients can help to identify the source of bleeding. While the work-up of patients with cirrhosis and OGIB is the same as with patients without cirrhosis, clinicians must be aware that there are conditions exclusive for patients with portal hypertension that can potentially cause OGIB. Recent Findings New endoscopic and imaging techniques are capable to identify sources of OGIB. Balloon-assisted enteroscopy (BAE) allows direct examination of the small-bowel mucosa and deliver specific endoscopic therapy. Conditions such as ectopic varices and portal hypertensive enteropathy are better characterized with the improvement in visualization by these techniques. New algorithms in the approach and management of these patients have been proposed. Summary There are new strategies for the approach and management of patients with cirrhosis and OGIB due to new develop- ments in endoscopic techniques for direct visualization of the small bowel along with the capability of endoscopic treatment for different types of lesions. Patients with cirrhosis may present with OGIB secondary to conditions associated with portal hypertension. Keywords Obscure gastrointestinal bleeding . Cirrhosis . Portal hypertension .

  • Angiodysplasia of Colon Or GI Tract
    Angiodysplasia of Colon or GI Tract Background Phillips first described a vascular (blood vessel) abnormality that caused bleeding from the large bowel in a letter to the London Medical Gazette in 1839. During the 1920s, cancers were considered the major source of GI bleeding/hemorrhage. However, in the 1940s and 1950s, diverticular disease was recognized as an important source of bleeding. In 1951, Smith described active bleeding from a diverticulum visualized through a sigmoidoscope. Galdabini first used the name angiodysplasia in 1974; however, confusion about the exact nature of these lesions resulted in a multitude of terms that included AVM = arteriovenous malformation, hemangioma, telangiectasia, and vascular ectasia. These terms have varying pathophysiologies, with a common presentation of GI bleeding and may be used interchangeably by many physicians. Angiodysplasia is a degenerative lesion of previously healthy blood vessels found most commonly in the right-side of colon. 77% of angiodysplasias are located in the cecum and ascending colon, 15% are located in the jejunum and ileum (small intestine), and the remainder are distributed throughout the GI tract. These lesions typically are nonpalpable and small (<5 mm). Angiodysplasia is the most common vascular abnormality of the GI tract. After diverticulosis, it is the second leading cause of lower GI bleeding in patients older than 60 years. Angiodysplasia may account for approximately 6% of cases of lower GI bleeding. It may be observed incidentally at colonoscopy in as many as 0.8% of patients older than 50 years. The prevalence for upper GI lesions is approximately 1-2%. Small bowel angiodysplasia may account for 30-40% of cases of GI bleeding of obscure origin.
