“…When interpreting the CT examinations of patients with GI bleeding, it is important for radiologists to understand the proper GI bleeding terminology to effectively communicate with referring clinicians and to provide clear and understandable radiology reports. The clinical terminology for the types of GI bleeding (4)(5)(6)(9)(10)(11)(12)(13)(14)(15)(16) and terms used when reporting the imaging findings of GI bleeding are included in Tables 1 and 2, respectively (2,4,13,15,(17)(18)(19)(20)(21).…”

Gastrointestinal (GI) bleeding is a common potentially life-threatening medical condition frequently requiring multidisciplinary collaboration to reach the proper diagnosis and guide management. GI bleeding can be overt (eg, visible hemorrhage such as hematemesis, hematochezia, or melena) or occult (eg, positive fecal occult blood test or iron deficiency anemia). Upper GI bleeding, which originates proximal to the ligament of Treitz, is more common than lower GI bleeding, which arises distal to the ligament of Treitz. Small bowel bleeding accounts for 5-10% of GI bleeding cases commonly manifesting as obscure GI bleeding, where the source remains unknown after complete GI tract endoscopic and imaging evaluation. CT can aid in identifying the location and cause of bleeding and is an important complementary tool to endoscopy, nuclear medicine, and angiography in evaluating patients with GI bleeding. For radiologists, interpreting CT scans in patients with GI bleeding can be challenging owing to the large number of images and the diverse potential causes of bleeding. The purpose of this pictorial review by the Society of Abdominal Radiology GI Bleeding Disease-Focused Panel is to provide a practical resource for radiologists interpreting GI bleeding CT studies that reviews the proper GI bleeding terminology, the most common causes of GI bleeding, key patient history and risk factors, the optimal CT imaging technique, and guidelines for case interpretation and illustrates many common causes of GI bleeding. A CT reporting template is included to help generate radiology reports that can add value to patient care.

“…Annual incidence is about 20 to 33 per 100 000 adults and in most cases bleeding is from large bowel. Incidence can be increased by age and presence of other gastrointestinal diseases and correlate with comorbidity (arterial hypertension, hepatic cirrhosis, and portal hypertensive colopathy) as well as polypharmacy (NSAIL, anticoagulants) ( 2 ). Visible rectal bleeding, as an important sign of colon disease, represent indication in 22% of all colonoscopies in adults ( 3 ).…”

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.

“…agement can sometimes be challenging for a number of reasons. Among technical issues that may be commonly encountered by the operator are difficulties in obtaining a clear view of the bleeding site for injection or clipping, and the presence of large or multiple sources of bleeding in the case of diverticular disease or malignant lesions, where tissue does not offer adequate binding sites for effective clipping [2].…”

Effectiveness of hemostatic powders in lower gastrointestinal bleeding: a systematic review and meta-analysis

et al. 2021

Background and study aims There is limited evidence on the effectiveness of hemostatic powders in the management of lower gastrointestinal bleeding (LGIB). We aimed to provide a pooled estimate of their effectiveness and safety based on the current literature. Patients and methods Literature review was based on computerized bibliographic search of the main databases through to December 2020. Immediate hemostasis, rebleeding rate, adverse events, and mortality were the outcomes of the analysis. Pooled effects were calculated using a random-effects model. Results A total of 9 studies with 194 patients were included in the meta-analysis. Immediate hemostasis was achieved in 95 % of patients (95 % confidence interval [CI] 91.6 %–98.5 %), with no difference based on treatment strategy or bleeding etiology. Pooled 7- and 30-day rebleeding rates were 10.9 % (95 %CI 4.2 %–17.6 %) and 14.3 % (95 %CI 7.3 %–21.2 %), respectively. Need for embolization and surgery were 1.7 % (95 %CI 0 %–3.5 %) and 2.4 % (95 %CI 0.3 %–4.6 %), respectively. Overall, two patients (1.9 %, 95 %CI 0 %–3.8 %) experienced mild abdominal pain after powder application, and three bleeding-related deaths (2.3 %, 95 %CI 0.2 %–4.3 %) were registered in the included studies. Conclusion Novel hemostatic powders represent a user-friendly and effective tool in the management of lower gastrointestinal bleeding.
