Acute lower gastrointestinal bleeding: Society of Gastrointestinal Endoscopy guidelines, 2021
In a recent development, the European experts have laid down recommendations on diagnosis and management of acute lower gastrointestinal bleeding.these have been put forth in Endoscopy.
Lower gastrointestinal bleeding (LGIB) has an estimated incidence of 33–87/100,000 and accounts for 3% of emergency surgical referrals. The diagnosis and treatment of LGIB remains a challenge for clinicians; identifying the source of bleeding is a clinical priority, and can be challenging in comparison with upper gastrointestinal bleeding (UGIB). The most common cause of LGIB is diverticular bleeding. Up to 60% of cases of diverticular bleeding can be classed as severe,and it is the most common indication for mesenteric embolisation in patients with LGIB.The second most frequent diagnoses are the benign anorectal conditions, such as haemorrhoids, fissures and rectal ulcers.
With this background,The European Society of Gastrointestinal Endoscopy (ESGE) Guidelines aimed to summarize the available evidence and provide guidance regarding the diagnosis and management of acute lower gastrointestinal bleeding (LGIB) focusing on the risk stratification of patients, the role of endoscopy and other modalities (interventional radiology, surgery) , and on the appropriate management of antithrombotic agents in patients presenting with acute LGIB.
A structured systematic literature search using keywords in English-language articles until August 31, 2020 in Ovid MEDLINE, EMBASE, Google Scholar, and the Cochrane Database of Systematic Reviews, was carried out. The hierarchy of studies included in this evidence-based guideline was, in decreasing order of evidence level, published systematic reviews/meta-analyses, randomized controlled trials (RCTs), prospective and retrospective observational studies, case series.Evidence on each key question was summarized using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, wherever applicable.
The key recommendations areas summerised below.
- ESGE recommends that the initial assessment of patients presenting with acute lower gastrointestinal bleeding should include: a history of co-morbidities and medications that promote bleeding; hemodynamic parameters; physical examination (including digital rectal examination); and laboratory markers. A risk score can be used to aid, but should not replace, clinician judgment. Strong recommendation, low quality evidence.
- ESGE recommends that, in patients presenting with a self-limited bleed and no adverse clinical features, an Oakland score of ≤ 8 points can be used to guide the clinician decision to discharge the patient for outpatient investigation. Strong recommendation, moderate quality evidence.
- ESGE recommends, in hemodynamically stable patients with acute lower gastrointestinal bleeding and no history of cardiovascular disease, a restrictive red blood cell transfusion strategy, with a hemoglobin threshold of ≤ 7 g/dL prompting red blood cell transfusion. A post-transfusion target hemoglobin concentration of 7–9 g/dL is desirable. Strong recommendation, low quality evidence.
v ESGE recommends, in hemodynamically stable patients with acute lower gastrointestinal bleeding and a history of acute or chronic cardiovascular disease, a more liberal red blood cell transfusion strategy, with a hemoglobin threshold of ≤ 8 g/dL prompting red blood cell transfusion. A post-transfusion target hemoglobin concentration of ≥ 10 g/dL is desirable.Strong recommendation, low quality evidence.
- ESGE recommends that, in patients with major acute lower gastrointestinal bleeding, colonoscopy should be performed sometime during their hospital stay because there is no high quality evidence that early colonoscopy influences patient outcomes.Strong recommendation, low quality of evidence.
- ESGE recommends that patients with hemodynamic instability and suspected ongoing bleeding undergo computed tomography angiography before endoscopic or radiologic treatment to locate the site of bleeding.Strong recommendation, low quality evidence.
- ESGE recommends withholding vitamin K antagonists in patients with major lower gastrointestinal bleeding and correcting their coagulopathy according to the severity of bleeding and their thrombotic risk. In patients with hemodynamic instability, we recommend administering intravenous vitamin K and four-factor prothrombin complex concentrate (PCC), or fresh frozen plasma if PCC is not available.Strong recommendation, low quality evidence.
- ESGE recommends temporarily withholding direct oral anticoagulants at presentation in patients with major lower gastrointestinal bleeding.Strong recommendation, low quality evidence.
- ESGE does not recommend withholding aspirin in patients taking low dose aspirin for secondary cardiovascular prevention. If withheld, low dose aspirin should be resumed, preferably within 5 days or even earlier if hemostasis is achieved or there is no further evidence of bleeding.Strong recommendation, moderate quality evidence.
- ESGE does not recommend routinely discontinuing dual antiplatelet therapy (low dose aspirin and a P2Y12 receptor antagonist) before cardiology consultation. Continuation of the aspirin is recommended, whereas the P2Y12 receptor antagonist can be continued or temporarily interrupted according to the severity of bleeding and the ischemic risk. If interrupted, the P2Y12 receptor antagonist should be restarted within 5 days, if still indicated.Strong recommendation, low quality evidence.
