RESUMO
BACKGROUND: Lower gastrointestinal bleeding (LGIB) is a common reason for emergency department visits and subsequent hospitalizations. Recent data suggests that low-risk patients may be safely evaluated as an outpatient. Recommendations for healthcare systems to identify low-risk patients who can be safely discharged with timely outpatient follow-up have yet to be established. The primary objective of this study was to determine the role of patient predictors for the patients with LGIB to receive urgent endoscopic intervention. METHODS: A retrospective chart review was performed on 142 patients. Data was collected on patient demographics, clinical features, comorbidities, medications, hemodynamic parameters, laboratory values, and diagnostic imaging. Logistic regression analysis, independent samples t-testing, Mann Whitney U testing for non-parametric data, and univariate analysis of categorical variables by Chi square test was performed to determine relationships within the data. RESULTS: On logistic regression analysis, A hemoglobin drop of > 20 g/L was the only variable that predicted endoscopic intervention (p = 0.030). Tachycardia, hypotension, or presence of anticoagulation were not significantly associated with endoscopic intervention (p > 0.05). CONCLUSIONS: A hemoglobin drop of > 20 g/L was the only patient parameter that predicted the need for urgent endoscopic intervention in the emergency department.

INTRODUCTION: Gastrointestinal bleeding results in significant morbidity, cost and mortality. TXA, an antifibrinolytic agent, has been proposed to reduce mortality; however, many studies report conflicting results. METHODS: The aim of the study was to perform the first systematic review and meta-analysis of RCTs to evaluate the efficacy TXA for both upper and lower gastrointestinal bleeding. This was performed per PRISMA guidelines. PubMed, EMBASE, Cochrane and Scopus databases were searched for RCTs. Dichotomous variables were pooled as risk ratios (RR) with 95% confidence intervals (CI) using the MH method with random effects modelling. RESULTS: Fourteen RCTs were identified with 14,338 patients and mean age of 58.4 years. 34.9% (n = 5008) were female and 65.1% (n = 9330) male. There was no significant difference in mortality between TXA and placebo (RR 0.86 95% CI (0.74 to 1.00), P: 0.05). The secondary outcomes, similarly, did not yield significant results. These included rebleeding, need for surgical intervention (RR: 0.75 95% CI (0.53, 1.07)), endoscopic intervention (RR: 0.92 95% CI (0.70, 1.22)), transfusion requirement (RR: 1.01 95% CI (0.94, 10.7)) and length of stay (RR: 0.03 95% CI (- 0.03, 0.08)). There was no increased risk of VTE, RR: 1.29 95% CI (0.53, 3.16). One trial (n = 12,009) reported an increased risk of seizure in the TXA group, RR: 1.73 95% CI (1.03-2.93). CONCLUSION: TXA does not reduce mortality in patients with acute upper or lower gastrointestinal bleeding and may confer an increased risk of seizures. The authors do not recommend the use of TXA in acute gastrointestinal bleeding.

BACKGROUND: Haematochesia (Lower Gastrointestinal Bleeding (LGIB) is the most common reason for endoscopic examination. Generaly it is caused by hemorrhoids and diverticular disease, but other anorectal conditions can also lead to LGIB. Recurrent bleeding may result in secondary iron deficiency anemia. Colonoscopy is the primary diagnostic option for establishing a diagnosis of colonic bleeding. OBJECTIVE: This study aimed to analyze symptoms and endoscopic finding (specialy hemorrhoids) who may be sources of LGIB.Second goal of this study is to estimate time from onset of symptoms to performance of a colonoscopy. METHODS: A retrospective study included 603 adult patients who underwent colonoscopy in General Hospital "Sv. Apostol Luka", Doboj, Bosnia and Herzegovina, between 1.1.2020 and 31.12.2020. RESULTS: Average age of the examined population was 62±13,3years. According to the gender they were mostly men. To be exact,by percentage it was 53.7% of men and 46,3% of women, or by number: 324 men and 279 women. The most common indications for colonoscopy were LGIB (48,8%), abdominal pain and irregular stool. Most frequent endoscopic findings were hemorrhoids 42%. Normal findings had almost one third of all examinated patients. Combined findings-presence of more clinical entities in one patient were presented in 95 cases. In the group with hemorrhoids were almost two thirds of males, but there was no gender difference noted in between group with LGIB and without LGIB. More than half patients were older than 61 years. Anemia was presented in almost 20% of cases. Significantly it is higher frequency of abdominal pain, irregular stool and weight loss observed on the group without LGIB. Also, significantly more frequently patients with LGIB underwent colonoscopy in 0-30 days when compared with patients without LGIB (p=0,016). CONCLUSION: In patients with haematochezia, taking a careful medical history is mandatory. Hemorrhoids, diverticular disease and colorectal cancers are the most common causes of bleeding. Patients with LGIB and abdominal pain were previously examined with colonoscopy. Completely colonoscopy is advocated to detect probable proximal lesions.

BACKGROUND AND AIMS: Lower Gastrointestinal Bleeding (LGIB) is one of the leading causes of ER visits. Colonoscopy is indicated in all patients with LGIB, yet the time frame for performing colonoscopy remains unclear. Whether or not urgent endoscopic evaluation improves outcomes of LGIB has been questioned. We therefore aimed to examine the success of urgent colonoscopy in identifying the source of LGIB. PATIENTS AND METHODS: A retrospective study was conducted in which timing of colonoscopy was divided into urgent (performed within the first 24 hours of presentation) and delayed (performed following 24 hours of hospitalization). Data on clinical presentation, investigations and endoscopic findings was collected. Risk ratios were calculated and regression analysis was used to examine associations and identify predictors of endoscopic success. RESULT: A total of 183 patients underwent colonoscopies. 55.4% of colonoscopies were performed within 24 hours of presentation. A source of LGIB was identified in 55.7% of first attempt colonoscopies. Endoscopic intervention was required in 10.9% of cases and rebleeding occurred in 24.6%, of which 6.5% required hospital re-admission. 2.7% required emergency colectomy and the calculated mortality rate was 1%. Risk ratios comparing urgent to delayed colonoscopy for source of LGIB identification, colectomy and mortality were 1.01, 4.8 and 1.2, respectively. Age and timing of colonoscopy appeared to be predictive of colectomy on regression analysis. CONCLUSIONS: Urgent colonoscopy for LGIB did not improve the rate of identification of the source of bleeding, colectomy rate or mortality rate and was predictive of the need for emergency colectomy.

AIMS: Colon preparation is vital yet more difficult in elderly patients with severe lower gastrointestinal bleeding (LGIB). The aim of this study is to show the efficacy, safety and outcomes of unprepared polyethylene glycol (PEG)-flush retrograde colon cleansing in the diagnosis and treatment of elderly home care patients with LGIB. METHODS: A single-center study was performed between January 2014 and June 2018. Elderly home healthcare patients presenting with hematochezia were enrolled, and an unprepared retrograde bowel cleansing colonoscopy was performed within the first 8 h after admission to the emergency department. PEG solution (2 L) was added to the water jet tank, and jet pump injection was started from the left side of the colon to the right segment of the colon and ended up at the cecum. RESULTS: In total, 33 elderly patients presenting with hematochezia were evaluated. Mean inward and outward procedure times were 17.06 ± 4.92 (8-33 min) and 28.66 ± 6.88 (10-30 min), respectively. Most of the bleeding was localized in the right colon at 22 patients (66.3%). Endoscopic treatment was performed in 87.9% of patients. The average length of stay in hospital was 44.70 ± 42.81 (range 18.00-240.00 h). CONCLUSIONS: Immediate unprepared PEG-flush colonoscopy in elderly home care patients with acute LGIB is a safe and effective method, which detects bleeding sources and provides endoscopic therapy. With this procedure, the time of hospital stay is reduced. This approach may be used for the initial intervention in patients admitted to emergency departments or intensive care unit with severe acute LGIB. Geriatr Gerontol Int 2020; â¢â¢: â¢â¢-â¢â¢.

BACKGROUND: Endoscopic intervention is often the first line of therapy for GI nonvariceal bleeding. Although some of the devices and techniques used for this purpose have been well studied, others are relatively new, with few available outcomes data. METHODS: In this document, we review devices and techniques for endoscopic treatment of nonvariceal GI bleeding, the evidence regarding their efficacy and safety, and financial considerations for their use. RESULTS: Devices used for endoscopic hemostasis in the GI tract can be classified into injection devices (needles), thermal devices (multipolar/bipolar probes, hemostatic forceps, heater probe, argon plasma coagulation, radiofrequency ablation, and cryotherapy), mechanical devices (clips, suturing devices, banding devices, stents), and topical devices (hemostatic sprays). CONCLUSIONS: Endoscopic evaluation and treatment remains a cornerstone in the management of nonvariceal upper- and lower-GI bleeding. A variety of devices is available for hemostasis of bleeding lesions in the GI tract. Other than injection therapy, which should not be used as monotherapy, there are few compelling data that strongly favor any one device over another. For endoscopists, the choice of a hemostatic device should depend on the type and location of the bleeding lesion, the availability of equipment and expertise, and the cost of the device.
RESUMO
This article summarizes current knowledge regarding the incidence of and risk factors associated with recurrent lower gastrointestinal hemorrhage. The literature regarding medical, endoscopic, and surgical methods to prevent rebleeding from diverticulosis, angioectasia, and chronic hemorrhagic radiation proctopathy is reviewed. In addition, the evidence for endoscopic clipping as primary prophylaxis against postpolypectomy bleeding is explored.

BACKGROUND AND STUDY AIMS: Lower gastrointestinal bleeding originates from a site distal to the ligament of Treitz. It can present as an acute life-threatening or chronicbleeding. It is common among older patients and those with comorbidity. The common causes are diverticular disease, angiodysplasias, neoplasms, colitis, ischaemia and anorectal disorders. The aim of this study is to determine the prevalence and causes of acute lower gastrointestinal bleeding among Sudanese patients. PATIENTS AND METHODS: In a period of 2 years we studied 301 patients with fresh rectal bleeding out of 5625 patients with gastrointestinal bleeding in Ibn Sina Specialized Hospital, Khartoum, Sudan, This is a cross sectional observational hospital based study. All patients with fresh rectal bleeding within 24â¯h were included and consented. RESULT: Lower gastrointestinal bleeding constituted 5.37% of total cases of gastrointestinal bleeding. The mean age of patients was 55.43⯱â¯17.779, male: female ratio was 2:1. The most common cause (if upper gastrointestinal bleeding is excluded) was diverticular disease 39.6% (nâ¯=â¯61) followed by piles 24.1% (nâ¯=â¯35), colonic tumours 12.34% (nâ¯=â¯19), ulcerative colitis 5.19% (nâ¯=â¯8), Crohn's 5.19% (nâ¯=â¯8), colonic polyps 3,89% (nâ¯=â¯6), angiodysplesia 4.5% (nâ¯=â¯7), colonic ulcer 2.59% (nâ¯=â¯4), ischaemic colitis 1.3%, nonspecific colitis 1.3% (nâ¯=â¯2), and small bowel source in 1.3% (nâ¯=â¯2). The majority of those patients with diverticular disease were male and with first presentation. The commonest cause in those patients younger than 20â¯years was polyps, and in those between 21 and 40 was piles followed by inflammatory bowel disease, and in those between 41 and 60â¯years old was piles followed by diverticular disease and tumours, and in those above 60â¯years was diverticular disease followed by piles and tumours. The correlation between positive colonoscopy finding and diabetes and the use of nonsteroidal anti-inflammatory drugs were statistically significant. The one-month mortality rate was 2.3% CONCLUSION: Acute lower gastrointestinal bleeding is common among elderly patients and the commonest cause is diverticular disease. Colonoscopy plays an important role in the diagnosis. Most patients respond to conservative therapy.

OBJECTIVE: The use of early colonoscopy in the management of acute lower gastrointestinal bleeding (LGIB) is controversial, with disparate evidence. We aim to formally characterize the utility of early colonoscopy (within 24 h) in managing acute LGIB. DESIGN: A systematic literature search to August 2016 identified fully published and abstracts of randomized controlled trials (RCTs) and observational studies assessing early colonoscopy in acute LGIB. Single-arm studies were also included to define incidence. Primary outcomes were overall rebleeding rates and time to rebleeding. Secondary outcomes included mortality, surgery, length of stay (LOS), definite cause of bleeding and adverse events (AEs). Odds ratios (OR) and weighted mean differences (WMD) were calculated. RESULTS: Of 897 citations, 10 single-arm, 9 observational studies, and 2 RCTS were included (25,781 patients). Rebleeding was no different between patients undergoing early colonoscopy and controls (seven studies, OR = 0.89, 95% CI 0.49-1.62), or RCT data only (OR = 1.00, 95% CI 0.52-1.62). Early colonoscopy detected more definitive sources of bleeding (OR = 4.12, 95% CI 2.00-8.49), and was associated with shorter LOS colonoscopy (WMD = -1.52, 95% CI -2.54 to -0.50 days). No other differences were noted between early and late colonoscopy. AEs occurred in 4.0%, (95% CI 2.9%; 5.4%) of early colonoscopies. Included studies were of low quality, with significant heterogeneity for some outcomes. CONCLUSION: Early colonoscopy in acute LGIB does not decrease rebleeding, mortality or need for surgery, but is associated with increased detection of definitive sources of bleeding, shorter LOS, with low complication incidence. However, the quality of evidence is low, highlighting the need for additional high-level studies.
RESUMO
BACKGROUND: Gastrointestinal bleeding (GIB) is a frequent cause of re-admission in patients with continuous-flow left ventricular assist devices (CF-LVADs) and is associated with multiple endoscopic procedures and high resource utilization. Our aim was to determine the diagnostic and therapeutic yield of endoscopy and to develop a more cost-effective approach for the management of GIB in CF-LVAD recipients. METHODS: We retrospectively reviewed 428 patients implanted with a CF-LVAD between 2009 and 2016 at the Columbia University Medical Center and identified those hospitalized for GIB. Patients were categorized into upper GIB (UGIB), lower GIB (LGIB) and occult GIB (OGIB), based on clinical presentation. RESULTS: Eighty-seven CF-LVAD patients underwent a total of 164 GIBs, resulting in 239 endoscopies. Index presentation was consistent with UGIB in 30 (34.5%), LGIB in 19 (21.8%) and OGIB in 38 (43.7%) patients. On the first GIB, 147 endoscopies localized a bleeding source in 49 (30%), resulting in 24 (16.3%) endoscopic interventions. Of 45 lesions identified, arteriovenous malformations (AVMs) were the most common (22, 48.9%). A gastric or small bowel source (HR 2.8, p = 0.003) and an endoscopic intervention (HR 1.9, p = 0.04) predicted recurrent GIB. The proposed algorithm may reduce the number of endoscopic procedures by 45% and costs by 35%. CONCLUSIONS: Occult GIB is the most common presentation in CF-LVAD patients and carries the lowest diagnostic and therapeutic yield of endoscopy. Performing an intervention was among the strongest predictors of recurrent GIB. Our proposed algorithm may decrease the number of low-yield procedures and improve resource utilization.

BACKGROUND & AIMS: The long-term recurrence of lower gastrointestinal bleeding (LGIB) and associated mortality have not been studied extensively. We investigated rates of recurrence of LGIB, mortality, and associated risk factors. METHODS: In a retrospective study, we analyzed data from 342 patients hospitalized for overt LGIB at the National Center for Global Health and Medicine in Japan from December 2004 through June 2013. All patients underwent colonoscopy. We assessed Charlson comorbidity index scores and the use of nonsteroidal anti-inflammatory drugs, low-dose aspirin, other antiplatelet drugs, or warfarin. Rebleeding, the total number of rebleeding episodes, and mortality were measured. The Cox proportional hazards model was used to estimate hazard ratios (HRs). RESULTS: Rebleeding occurred in 84 patients, at a mean follow-up time of 19 months. The cumulative percentages of patients with rebleeding at 1 and 5 years were 19% and 46%, respectively. During the follow-up period, 29 patients (39%) had secondary rebleeding and 18 patients (62%) had subsequent rebleeding. Multivariate analysis showed age 65 years and older (HR, 1.7; P = .04) and the use of nonsteroidal anti-inflammatory drugs (HR, 2.0; P < .01) and nonaspirin antiplatelet drugs (HR, 1.8; P < .05) as independent risk factors for rebleeding. Dual therapy had a higher risk than single therapy (adjusted HR, 1.8; P < .05). During the mean follow-up period of 28 months, 21 patients died (2 from bleeding). Cumulative mortality rates at 1 and 5 years were 4.2% and 13%, respectively. Mortality was associated significantly with age ≥65 years (P < .05), Charlson comorbidity index score, and warfarin use. CONCLUSIONS: Based on a retrospective analysis of patients with LGIB, 46% of all patients have rebleeding, and the overall mortality rate is 13% within 5 years after hospitalization. Besides age ≥65 years, use of antithrombotic drugs increases the risk of bleeding recurrence and mortality among patients with LGIB.

BACKGROUND: The role of urgent colonoscopy in lower GI bleeding (LGIB) remains controversial. Population-based studies on LGIB outcomes are lacking. OBJECTIVE: To investigate the impact of the timing of colonoscopy on outcomes of patients with LGIB. DESIGN: Cross-sectional study. SETTING: Nationwide Inpatient Sample 2010. PATIENTS: International Classification of Diseases, Ninth Revision, Clinical Modification codes identified patients with LGIB who underwent colonoscopy. MAIN OUTCOME MEASUREMENTS: In-hospital mortality, length of stay, and hospitalization costs in patients who underwent early (≤24 hours) or delayed (>24 hours) colonoscopy. RESULTS: A total of 58,296 discharges with LGIB were identified; 22,720 had a colonoscopy performed during the hospitalization. A total of 9156 patients had colonoscopy performed within 24 hours (early colonoscopy), and 13,564 had colonoscopy performed after 24 hours (delayed colonoscopy). There was no difference in mortality in patients with LGIB who had early versus delayed colonoscopy (0.3% vs 0.4%, P = .24). However, patients who underwent early colonoscopy had a shorter length of hospital stay (2.9 vs 4.6 days, P < .001), decreased need for blood transfusion (44.6% vs 53.8%, P < .001), and lower hospitalization costs ($22,142 vs $28,749, P < .001). On multivariate analysis, timing of colonoscopy did not affect mortality (adjusted odds ratio 1.5; 95% confidence interval, 0.7-2.7). On multivariate analysis, delayed colonoscopy was associated with an increase in the length of hospital stay by 1.6 days and an increase in hospitalization costs of $7187. LIMITATIONS: Administrative dataset. CONCLUSIONS: Early colonoscopy within 24 hours is associated with decreased length of hospital stay and hospitalization costs in patients with LGIB.

PURPOSE: To assess the safety and efficacy of transcatheter arterial embolization for lower gastrointestinal bleeding (LGIB) and to determine the prognostic factors that affect clinical outcome. MATERIALS AND METHODS: All patients diagnosed with LGIB by angiography at a single institution from April 2006 to January 2013 were included in a retrospective study. The rates of technical success, early recurrent bleeding, major complications, clinical success, and in-hospital mortality for transcatheter arterial embolization were determined. The influence of possible prognostic factors on the outcome was analyzed. RESULTS: A total of 112 patients were included (36 with small-bowel LGIB, 36 with colon LGIB, and 40 with rectal LGIB). N-butyl cyanoacrylate (NBCA) was the embolic agent for 84 patients (75.0%), whereas gelatin sponge pledgets (n = 20), microcoils (n = 2), polyvinyl alcohol particles with adjunctive gelatin sponge pledgets (n = 1), and blood clots (n = 1) were used in the other patients. The technical success rate was 96.4%. For the entire group, the rates of early recurrent bleeding, major complications, clinical success, and in-hospital mortality were 17.4%, 4.6%, 74.5%, and 25.0%, respectively. These were 15.2%, 4.8%, 75.3%, and 26.2%, respectively, in the NBCA group. Hematologic malignancy, immobilization status, and coagulopathy were significant prognostic factors for clinical outcomes. CONCLUSIONS: Transcatheter arterial embolization is a safe and effective treatment for LGIB. NBCA could be used as a primary embolic agent for this procedure.

BACKGROUND: Data on the use of endoscopic hemostasis performed during colonoscopy for hematochezia are primarily derived from expert opinion and case series from tertiary care settings. OBJECTIVES: To characterize patients with hematochezia who underwent in-patient colonoscopy and compare those who did and did not receive endoscopic hemostasis. DESIGN: Retrospective analysis. SETTING: Clinical Outcomes Research Initiative National Endoscopic Database, 2002 to 2008. PATIENTS: Adults with hematochezia. INTERVENTIONS: None. MAIN OUTCOME MEASUREMENTS: Demographics, comorbidities, practice setting, adverse events, and colonoscopy procedural characteristics and findings. RESULTS: We identified 3151 persons who underwent in-patient colonoscopy for hematochezia. Endoscopic hemostasis was performed in 144 patients (4.6%). Of those who received endoscopic hemostasis, the majority were male (60.3%), white (83.3%), and older (mean age 70.9 ± 12.3 years); had a low-risk American Society of Anesthesiologists classification (53.9%); and underwent colonoscopy in a community setting (67.4%). The hemostasis-receiving cohort was significantly more likely to be white (83.3% vs 71.0%, P = .02), have more comorbidities (classes 3 and 4, 46.2% vs 36.0%, P = .04), and have the cecum reached (95.8% vs 87.7%, P = .003). Those receiving hemostasis were significantly more likely to have an endoscopic diagnosis of arteriovenous malformations (32.6% vs 2.6%, P = .0001) or a solitary ulcer (8.3% vs 2.1%, P < .0001). LIMITATIONS: Retrospective database analysis. CONCLUSIONS: Less than 5% of persons presenting with hematochezia and undergoing inpatient colonoscopy received endoscopic hemostasis. These findings differ from published tertiary care setting data. These data provide new insights into in-patient colonoscopy performed primarily in a community practice setting for patients with hematochezia.
