Abstract
Acute decompensation (AD) of cirrhosis is defined by the development of ascites, hepatic encephalopathy and/or variceal bleeding. Ascites is traditionally attributed to splanchnic arterial vasodilation and left ventricular dysfunction, hepatic encephalopathy to hyperammonaemia, and variceal haemorrhage to portal hypertension. Recent large-scale European observational studies have shown that systemic inflammation is a hallmark of AD. Here we present a working hypothesis, the systemic inflammation hypothesis, suggesting that systemic inflammation through an impairment of the functions of one or more of the major organ systems may be a common theme and act synergistically with the traditional mechanisms involved in the development of AD. Systemic inflammation may impair organ system function through mechanisms which are not mutually exclusive. The first mechanism is a nitric oxide-mediated accentuation of the preexisting splanchnic vasodilation, resulting in the overactivation of the endogenous vasoconstrictor systems which elicit intense vasoconstriction and hypoperfusion in certain vascular beds, in particular the renal circulation. Second, systemic inflammation may cause immune-mediated tissue damage, a process called immunopathology. Finally, systemic inflammation may induce important metabolic changes. Indeed, systemic inflammatory responses are energetically expensive processes, requiring reallocation of nutrients (glucose, amino acids and lipids) to fuel immune activation. Systemic inflammation also inhibits nutrient consumption in peripheral (non-immune) organs, an effect that may provide one mechanism of reallocation and prioritisation of metabolic fuels for inflammatory responses. However, the decrease in nutrient consumption in peripheral organs may result in decreased mitochondrial production of ATP (energy) and subsequently impaired organ function.

Management of Non-Variceal Upper GI Bleeding in the Geriatric Population: An Update.
Stolow, E, Moreau, C, Sayana, H, Patel, S
Current gastroenterology reports. 2021;(4):5
Abstract
PURPOSE OF REVIEW Upper gastrointestinal (GI) bleeding is a significant cause of morbidity and mortality in the geriatric (age > 65 years) population and presents a unique management challenge in the context of multiple medical comorbidities, polypharmacy, and increased risk of adverse outcomes and is confounded by an increased prevalence of obscure GI bleeds. A review of relevant guidelines, literature, and personal observations will enhance management strategies in the elderly. RECENT FINDINGS Non-variceal bleeding represents a significant proportion of upper GI bleeding (UGIB) in geriatric patients. Peptic ulcer disease (PUD) remains the most common cause in geriatric patients hospitalized for UGIB, but its incidence is decreasing. Esophagogastroduodenoscopy (EGD) is the gold standard for treating UGIB in geriatrics with a therapeutic yield of approximately 75%. Scoring systems such as Glasgow-Blatchford (GBS) and AIMS-65 may be useful for risk stratification but are not validated in trials. Obscure bleeds account for up to 30% of hospitalizations and must be considered during triage and management. Video capsule endoscopy (VCE) technology is efficacious for detecting obscure jejunal bleeding after failed EGD and may enhance the yield of balloon-assisted enteroscopy (BAE). The most significant factor for the increased morbidity and mortality in the geriatric population is the presence of multiple medical comorbidities and polypharmacy. An EGD should be done within 24 h of hospital presentation. If non-diagnostic, VCE may be a viable option for diagnosing an obscure small-bowel bleed, representing up to 30% of GI bleeds in this population.

Gastric Inflammatory Fibroid Polyp: A Rare Cause of Occult Upper Gastrointestinal Bleeding.
Inayat, F, Ur Rahman, A, Wahab, A, Riaz, A, Zahid, E, Bejarano, P, Pimentel, R
Journal of investigative medicine high impact case reports. 2020;:2324709620936840
Abstract
Inflammatory fibroid polyps (IFPs) are rare mesenchymal lesions that can arise throughout the gastrointestinal tract. These tumors represent less than 0.1% of all gastric polypoid lesions and are frequently found incidentally on endoscopic evaluation. While presenting symptoms depend on the location of the tumor, gastric polyps commonly present with epigastric pain and early satiety. We hereby delineate the case of a middle-aged female who presented with chronic iron deficiency anemia and a positive fecal occult blood test. She underwent an upper endoscopy, which revealed an actively oozing umbilicated lesion in the gastric antrum. Endoscopic ultrasound divulged the submucosal origin of the lesion. It was subsequently excised using endoscopic mucosal resection. Pathologic examination of the resected specimen confirmed the diagnosis of gastric IFP. Furthermore, we conducted a systematic literature search of the MEDLINE database centered on gastric IFPs from January 2000 till March 2020. The data on patient demographics, clinical features, endoscopic findings, lesion site and size, and treatment approaches were collected and analyzed. This article illustrates the overarching need for clinicians to be vigilant of gastric IFPs presenting with initial clinical symptoms suggestive of occult upper gastrointestinal bleeding. Prompt diagnosis and management of gastric IFPs carry paramount importance to combat chronic unexplained iron deficiency anemia following occult bleeding in such patients. A concoction of endoscopy, biopsy, and immunohistochemical examination can be employed toward their prompt detection. Although gastric IFPs have conventionally been treated with surgery, endoscopic resection is now emerging as a safe and efficient therapeutic modality.

Dual-energy CT evaluation of gastrointestinal bleeding.
Trabzonlu, TA, Mozaffary, A, Kim, D, Yaghmai, V
Abdominal radiology (New York). 2020;(1):1-14
Abstract
Gastrointestinal bleeding is a common cause for hospital admissions and is an important cause of morbidity and mortality. Although endoscopy is accepted as the standard initial diagnostic modality for the evaluation of gastrointestinal bleeding, multiphasic computed tomography (CT) imaging has become an alternative diagnostic tool. Dual-energy CT with post-processing techniques may have additional advantages over single-energy computed tomography in evaluation of gastrointestinal bleeding. In this article, we discuss the role of dual-energy CT in the evaluation of gastrointestinal bleeding with potential advantages over conventional CT and limitations.

Abstract
BACKGROUND Controversy persists about whether early enteral nutrition administration is related to worse prognosis than delayed enteral nutrition for patients with gastrointestinal bleeding. OBJECTIVES To systematically evaluate the effect of early enteral nutrition on the patient with gastrointestinal bleeding through the meta-analysis. METHODS Such electronic databases including PubMed, EMBASE, Cochrane Library, CNKI, and CBM were searched from 1985 to March 2018. Randomized controlled trials that compared early enteral nutrition versus delayed enteral nutrition in patients with gastrointestinal bleeding were considered eligible. Data extraction and the methodological quality assessment of the included trials were carried out according to the Cochrane Handbook. We calculated the pooled risk ratio, weighted mean difference, and the corresponding 95% confidential interval using RevMan5.3. RESULT A total of 5 trials involving 313 patients were included. Compared with delayed enteral nutrition, there was a tendency for a decreased rebleeding rate in the early enteral nutrition group, but the trend was not statistically significant (risk ratio = 0.75, 95% confidential interval: 0.34-1.64, I = 0). As for mortality within 30 days, no significant difference was found between the 2 groups (risk ratio = 0.74, 95% confidential interval: 0.23-2.39, I = 0). In addition, the pooled analysis showed that early enteral nutrition was related to reduced hospitalized days (weighted mean difference = -1.69, 95% confidential interval: -2.15 to -1.23; I = 27%) CONCLUSION For patients with gastrointestinal bleeding, early enteral nutrition within 24 hours does not result in the significantly higher risk of rebleeding and mortality compared with delayed enteral nutrition, but decrease hospitalized days. Patients who are at low risk for rebleeding can be fed early and discharged early. However, larger, high-quality randomized controlled trials are needed to verify these findings, and when the gastrointestinal bleeding patient start enteral nutrition is worth studying.

Use of Enteral Nutrition for Gastrointestinal Bleeding Prophylaxis in the Critically Ill: Review of Current Literature.
Newberry, C, Schucht, J
Current nutrition reports. 2018;(3):116-120
Abstract
PURPOSE OF REVIEW This review provides a comprehensive overview of the etiology of stress-related mucosal disease, current acid suppression therapy recommendations, and the role enteral nutrition may play in disease prevention. RECENT FINDINGS Recent literature indicates enteral nutrition may prevent complications of stress-related mucosal disease by increasing splanchnic blood flow, enhancing gastrointestinal motility, and promoting cellular immunity and integrity through local nutrient delivery. Stress-related mucosal disease is a common complication of hospitalization in the critically ill which may lead to overt gastrointestinal bleeding and enhanced mortality. High-risk patients have historically been prescribed acid suppression therapy, though enteral nutrition may also have a role in disease mitigation.

Portal hypertension and its management in children.
Grammatikopoulos, T, McKiernan, PJ, Dhawan, A
Archives of disease in childhood. 2018;(2):186-191
Abstract
Portal hypertension (PHT), defined as raised intravascular pressure in the portal system, is a complication of chronic liver disease or liver vascular occlusion. Advances in our ability to diagnose and monitor the condition but also predict the risk of gastrointestinal bleeding have enabled us to optimise the management of children with PHT either at a surveillance or at a postbleeding stage. A consensus among paediatric centres in the classification of varices can be beneficial in streamlining future paediatric studies. New invasive (endoscopic and surgical procedures) and non-invasive (pharmacotherapy) techniques are currently used enabling clinicians to reduce mortality and morbidity in children with PHT.

Dima, A, Jurcut, C, Manolache, A, Balaban, DV, Popp, A, Jinga, M
Journal of gastrointestinal and liver diseases : JGLD. 2018;(1):93-99
Abstract
BACKGROUND AND AIMS Celiac disease (CD) presents with a wide spectrum of extra-digestive symptoms, including hemorrhagic manifestations. The aim of this review was to conduct an extensive analysis of the hemorrhagic events reported in adult CD patients. METHODS Case report and review of the literature. Pubmed (MEDLINE) database search from January 1970 onwards was performed using the medical subject headings [MeSH] terms "celiac disease" AND "blood coagulation disorders", "hemorrhage", "hematoma", "hematuria", "hemoptysis", "epistaxis", "hemosiderosis". Only case reports were identified on the search theme. Information on patients' characteristics, diagnostic features, coagulation parameters, symptomatology duration, and evolution under treatment were systematically collected and summarized. RESULTS We present the case of a 40-year-old man hospitalized for spontaneous muscular hematomas, in whom CD was diagnosed. We performed a review of the literature and summarized the published case reports of 46 CD patients, aged between 19 and 74 years, 64% of male gender. In 25% of cases, the symptomatology was present for more than 5 years prior to CD diagnosis. The clinical hemorrhagic events were as follows: 15 patients had gastrointestinal bleeding, 9 hemoptysis, 4 epistaxis, 6 hematuria, 8 cutaneous hematoma, petechia or ecchymoses, and only in 1 case hemarthrosis, hemorrhagic vesicular dermatitis, subcortical hemorrhage, or adrenal hemorrhage. Sixty percent of the patients had digestive symptoms, while the rest had only extra-digestive CD involvement. The Lane Hamilton syndrome was defined in 15 patients. The evolution under a gluten-free diet was favorable in most cases. CONCLUSION This review of case reports aims to increase awareness to hemorrhagic events, rare but possible life-threatening conditions, as part of the CD clinical spectrum. To the best of our knowledge, this is the first review of all types of hemorrhagic events in adult CD patients.

Abstract
BACKGROUND Gallstone ileus is a non-strangulated mechanical obstruction of the small bowel or colon as a result of the passage of gallstones through a biliary enteric fistula. It is a rare complication of cholelithiasis, affects patients over 65 years, and the disease occurs predominantly in females. Preoperative diagnosis is difficult due to the lack of specific signs and symptoms in elderly patients with multiple comorbidities. CLINICAL CASE A 93-year-old female presenting with a one-week history of upper gastrointestinal bleeding, electrolyte imbalance and community- acquired pneumonia pneumonia. During her prolonged hospital stay she presented an intestinal obstruction. The diagnosis of gallstone ileus was made by CT scan. Despite surgical treatment, she died due to late diagnosis. CONCLUSIONS Gallstone ileus is a rare pathology, difficulty in diagnosis prolongs hospital stay, which directly influences mortality.
