Abstract
Introduction Angiodysplasia, a rare cause of gastrointestinal (GI) bleeding, presents a spectrum of clinical manifestations from anemia to life-threatening hemorrhage. This case study emphasizes the significance of considering intestinal vascular malformations as a differential diagnosis, especially in the context of chronic anemia and GI bleeding. Jejunal angiodysplasia, though infrequent, poses diagnostic challenges due to the hidden nature of the small bowel in the GI system. Case presentation A 23-year-old male presented with acute hematochezia and melena, necessitating prompt intervention. Despite a normal esophagogastroduodenoscopy, colonoscopy was hindered, CT angiography could not be performed due to the patient's unstable condition, leading to a planned exploratory laparotomy. Surgical exploration revealed a mucosal vascular lesion in the jejunum, prompting resection, and anastomosis. The patient's postoperative course was uneventful, reinforcing the importance of swift diagnosis and intervention. Clinical discussion Angiodysplasia's pathogenesis remains unclear, with hypotheses implicating vascular endothelial growth factor and submucosal changes. Challenges in management revolve around lesion localization and stabilizing hemodynamics, necessitating a multidisciplinary approach. While endoscopy is often diagnostic and therapeutic, advanced modalities such as CT angiography may be required. Literature review highlights diverse presentations and successful interventions, including embolization and surgical resection. Conclusion Jejunal angiodysplasia demands a comprehensive diagnostic and therapeutic strategy. The presented case underscores the pivotal role of endoscopy, embolization, and surgery in managing this condition. Timely diagnosis and intervention are crucial for mitigating the impact of angiodysplasia, necessitating further research and collaborative efforts for improved management of this rare condition.

Abstract
The association between aortic stenosis and increased gastrointestinal arteriovenous malformations is known as Heyde's syndrome. An acquired von Willebrand deficiency mediates the connection between these two seemingly dispersed pathologies. As von Willebrand factor passes through a stenosed aorta, it is broken down and can no longer inhibit angiogenesis, leading to angiodysplasias. Heyde's syndrome can manifest with chronic, refractory anemia requiring multiple hospitalizations for symptomatic gastrointestinal bleeding and transfusion. Hitherto, Heyde's syndrome has been considered exceptionally rare, with 1-3% of populations with aortic stenosis. However, given that 31.7% of patients with gastrointestinal angioplasty have aortic stenosis and gastrointestinal arteriovenous malformations are not screened for in patients without anemia, the prevalence of Heyde's syndrome is most likely higher than currently reflected in the literature. Also, the prevalence of Heyde's syndrome in populations who are predisposed to angiodysplasias, such as those on hemodialysis, is understudied. We aim to impart a need for increased research on the prevalence of Heyde's syndrome, especially in high-risk patients. This case report presents a patient with severe Heyde's syndrome on hemodialysis, showing an unconsidered risk factor for Heyde's syndrome in need of further research.

Abstract
Gastrointestinal angiodysplasias (GIADs) are rare disorder but can cause noticeable issue clinically. Their clinical characteristics can range from being an asymptomatic incidental finding to causing life-threatening bleeding. Many modalities are applied for treating bleeding GIADs include endoscopic therapies, angiography with embolization, surgical resection, and pharmacologic therapy. However, since patients with GIADs are often aged and have many comorbidities, endoscopic therapies may not be the best initial option. Angiography is suitable method for hemodynamically unstable patients with active bleeding, patients with an unknown active bleeding source, and patients who are poor surgical candidates. Angiography not only diagnose the bleeding point but also provide therapeutic endovascular intervention at the same time. We report a case of endovascular management of severe lower gastrointestinal bleeding from a GIAD in the cecum using a mixture of n-butyl cyanoacrylate and lipiodol to embolize the bleeding source. Clinical symptoms improved without prominent complications.

Abstract
With the aging of the population, the incidence of senile degenerative valvular heart disease is expected to increase. Transcatheter aortic valve replacement (TAVR) has been used for patients at lower surgical risk with symptomatic severe aortic valve stenosis. Because of the improvements in TAVR technology and increasing experience of the operators, TAVR is regarded as a safe and feasible procedure. Bleeding events during the TAVR perioperative period, especially gastrointestinal (GI) bleeding, have been proven to be related to the long-term prognosis and mortality. Elderly patients with valvular heart disease are susceptible to GI bleeding because of their use of antithrombotic drugs, physical damage of coagulation factors, and GI angiodysplasia. Frequent GI bleeding and low levels of preoperative hemoglobin increase the risk of TAVR, especially for elderly patients. Because of these risks, which are easily overlooked, we should focus more attention on the perioperative management of TAVR. Reasonable screening tools, including blood examinations, risk evaluation scales, and endoscopy, are beneficial to the prevention of complications that can occur during the perioperative period. Additionally, medical therapy can safely help patients at high-risk for bleeding patients throughout the perioperative period. This study aimed to characterize the pathology of TAVR patients and discuss treatment strategies for GI bleeding during the perioperative period.

Abstract
INTRODUCTION Angiodysplasias are responsible of 50% of small bowel bleeding. An endoscopic method that allows measuring its severity is not available. AIMS The aim of the study was to validate a new endoscopic score with VCE to measure the severity of small bowel angiodysplasias (SBAD). METHODS Four endoscopists independently reviewed VCE videos of 22 patients with SBAD. The score graded 3 variables: A - extent of lesions: E1, located in one half of the intestine and E2, in both halves; B - number of lesions: N1, <5; N2, 5-10; and N3, >10 lesions; C - probability of bleeding: P1, pale red spots; P2, bright red spots; P3, bleeding stigmata; and P4, active bleeding. Capsule Endoscopy Small Bowel Angiodysplasia Activity Index (CESBAI) was calculated as follows: E × 1 + N × 2 + P × 3. Interobserver variability was analyzed by Spearman's correlation and agreement Kappa statistic tests. RESULTS The mean CESBAI scores by observers were O1= 11.6 ± 4.1; O2 = 11.3 ± 4.8; O3 = 11.1 ± 4.9; and O4 = 11.8 ± 4.2 (p > 0.05). Spearman's correlation values of CESBAI between every 2 observers were from 0.61 to 0.94 (p < 0.001) with a global correlation of 0.73 among all observers. Kappa values of CESBAI between every 2 observers ranged from 0.42 to 0.87 (p < 0.001) with a global agreement of 0.57 among all observers. All evaluators stated that the method was easy to use. CONCLUSIONS CESBAI is a reliable and reproducible score. Nevertheless, these results must be validated in other studies with larger population before assessing its power for predicting bleeding recurrence.

Abstract
The gastrointestinal tract is a long tubular structure wherein any point in the mucosa along its entire length could be the source of a hemorrhage. Upper (esophagel and gastroduodenal) and lower (jejunum, ileum, and colon) gastrointestinal bleeding are common. Gastroduodenal and colonic bleeding are more frequent than bleeding from the small bowel, but nowadays the entire gastrointestinal tract can be explored endoscopically and bleeding lesions can be locally treated successfully to stop or prevent further bleeding. The extensive use of antiplatelet and anticoagulants drugs in cardiovascular patients is, at least in part, the cause of the increasing number of patients suffering from gastrointestinal bleeding. Patients with these conditions are usually older and more fragile because of their comorbidities. The correct management of antithrombotic drugs in cases of gastrointestinal bleeding is essential for a successful outcome for patients. The influence of the microbiome in the pathogenesis of small bowel bleeding is an example of the new data that are emerging as potential therapeutic target for bleeding prevention. This text summarizes the latest research and advances in all forms of acute gastrointestinal bleeding (i.e., upper, small bowel and lower). Diagnosis is approached, and medical, endoscopic or antithrombotic management are discussed in the text in an accessible and comprehensible way.

Abstract
Arteriovenous malformations (AVM) are most commonly found in the gastrointestinal tract, and presentation can range from asymptomatic to massive gastrointestinal hemorrhage. This case highlights a unique presentation of AVMs. During a screening colonoscopy, a 5-cm mass was discovered in the transverse colon encompassing 25% to 50% of the circumference of the lumen. Biopsies showed polypoid AVM with overlying inflammatory polyps without evidence of malignancy or dysplasia. There are many treatment options for AVM removal. In this case, since suspicion for malignancy was high, the patient underwent surgery and will be closely monitored.

Abstract
Angiodysplasia is a common type of lesion characterized by malformed submucosal and mucosal blood vessels. Angiodysplasia of the gallbladder is extremely rare, usually an incidental finding, with only two cases reported. Laparoscopic cholecystectomy is a curative treatment for angiodysplasia of the gallbladder. Our report describes a case of angiodysplasia of the gallbladder in a patient who underwent elective laparoscopic cholecystectomy for biliary colic because of gallstones, and a systematic literature review. We surmise that angiodysplasia of the gallbladder could be a risk factor for gallstones in younger female patients.

Abstract
BACKGROUND Angiodysplasia is the second most common vascular abnormality of the GI tract after diverticulosis and is the second principal cause of lower GI bleeding over 60 years. CASE REPORT A 68-year-old male patient presented to our institute in the outpatient clinic with pallor of gradual onset and progressive course since 6 months. Detailed history revealed hematochezia, sometimes melena. Physical examination revealed signs of iron deficiency anemia which was confirmed by laboratory results and hemoccult positive stool. The patient refused the colonoscopy. A bdominal CT with contrast was then performed which revealed an evidence of abnormal subtle mural contrast flocculation within the small bowel loop with luminal extravasations of contrast at small segment of distal ileum few centimeters from ileocaecal valve with mildly dilated and early filling of its drained vein, this abnormal contrast extravasations and flocculation increased through dynamic study. In addition, evidence of contrast mural flocculation within the left lateral wall of distal few centimeters of rectum was also observed. This abnormal mural contrast flocculation within the wall of solitary segment terminal ileum and distal rectum suggest the evidence of venous ectasia or angiodysplasia. Surgical resection was done with end to end anastomosis of the small intestine without any complication in the postoperative progress. CONCLUSION This case also emphasizes the critical significance of a mutual multidisciplinary approach to occult gastrointestinal bleeding. The management of angiodysplasia is considered as multidisciplinary team work that would consist of expertise from different departments as in endoscopy, angiography, and gastrointestinal surgery.

Abstract
Objectives: Small bowel angioectasia (SBA) plays an important role in the etiologies of obscure gastrointestinal haemorrhage. But the exact prevalence of the disease is unknown, especially in asymptomatic populations. Therefore, we aimed to evaluate the prevalence of asymptomatic angioectasia in the small bowel (SB) with magnetically controlled capsule gastroscopy (MCCG).Methods: We retrospectively collected a multicentre clinical data of 508 asymptomatic patients who underwent MCCG from June 2018 to May 2019. Bowel cleanliness was rated as four grades according to the criteria, and the excellent or good preparation was classified as the adequate group. The detection rates of small bowel lesions were analysed according to the ages, genders and bowel preparations.Results: A total of 508 individuals have completed the examination. There were 316 men and 192 women with an average age of 44.5 years old. The prevalence of SBA was 11.8% (95% CI: 9.0-14.6%). 70.0% of them were over 40 years old and 73.3% were male although there was no obvious disparity found in age and gender for the SBA. Most findings were located in the proximal small bowel (jejunum). The incidence of small bowel lesions was not related to bowel preparations (p > .05).Conclusions: SBA is not uncommon in asymptomatic individuals. Age and gender may be risk factors for bleeding of angioectasia in the small bowel, but they seem to have little to do with the occurrence of it. MCCG showed no difference in ages, genders or bowel preparations of small bowel lesions among our study population.

Abstract
Gastrointestinal angiodysplasias (GIADs), also called angioectasias, are the most frequent vascular lesions. Its precise prevalence is unknown since most of them are asymptomatic. However, the incidence may be increasing since GIADs affect individuals aged more than 60 years and population life expectancy is globally increasing worldwide. They are responsible of about 5% to 10% of all gastrointestinal bleeding (GIB) cases. Most GIADs are placed in small bowel, where are the cause of 50 to 60% of obscure GIB diagnosed with video capsule endoscopy. They may be the cause of fatal severe bleeding episodes; nevertheless, recurrent overt or occult bleeding episodes requiring repeated expensive treatments and disturbing patient’s quality-of-life are more frequently observed. Diagnosis and treatment of GIADs (particularly those placed in small bowel) are a great challenge due to insidious disease behavior, inaccessibility to affected sites and limitations of available diagnostic procedures. Hemorrhagic causality out of the actively bleeding lesions detected by diagnostic procedures may be difficult to establish. No treatment guidelines are currently available, so there is a high variability in the management of these patients. In this review, the epidemiology and pathophysiology of GIADs and the status in the diagnosis and treatment, with special emphasis on small bowel angiodysplasias based on multiple publications, are critically discussed. In addition, a classification of GIADs based on their endoscopic characteristics is proposed. Finally, some aspects that need to be clarified in future research studies are highlighted.

Abstract
Background: Angioectasias are a prominent cause of small bowel (SB) bleeding frequently identified during capsule endoscopy (CE). Subsequent management depends upon grade/severity and location. There is increasing evidence that the location of SB angioectasias is not random. We aimed to map the distribution of SB angioectasias, and assess whether this impacted clinical outcomes. Materials and methods: Retrospective study examining CEs performed over a 10-year period at a tertiary referral centre. Information regarding number, location, and Saurin classification (P0-2) of SB angioectasias was collected. Clinically significant angioectasias (P1/P2) and active SB bleeding were analysed further. Outcomes of patients with P2 angioectasias or active SB bleeding were recorded. Results: 164 SBCE examinations reported angioectasias. 554 P1-2 angioectasias and active bleeds were seen, 435 (78.52%) within the first tertile of SB transit time (SBTT). 277 (50%) angioectasias were identified within the first 10% of SBTT. 40/75 (53.3%) patients with >1 P2 angioectasia and/or active bleed were referred for intervention. Of initial interventions, 24 patients underwent upper GI endoscopy; 13 underwent double balloon enteroscopy (DBE). 9/37(24.3%) had no identifiable angioectasias on endoscopy. Of those receiving ablative therapy, 20/28 (71.4%) re-presented with iron-deficiency anaemia or bleeding. In this group, average angioectasia position was 15.6% of SBTT, compared with 7.9% in those who did not re-represent (p = 0.344). Patients who re-presented had an average 1.6 additional P1 angioectasias, compared with 7.6 amongst those who did not return (p = 0.017). Conclusions: Clinically significant angioectasias are overwhelmingly located within the proximal SB. The majority are within reach of conventional endoscopy. However, AEs are often multiple and many patients re-present following intervention.

Abstract
OBJECTIVE This study aims to assess the efficacy of hormone therapy in patients with severe gastrointestinal bleeding due to multiple angiodysplastic lesions. PATIENTS AND METHODS Between May 2010 and July 2017, we included 12 consecutive patients with anaemia or recurrent bleeding due to angiodysplasia who had been started on hormone therapy. The therapy given was a combination of levonorgestrel (between 0.10 and 0.25 mg) and ethinylestradiol (between 0.02 and 0.05 mg). We determined the mean number of transfusions required in the 6 months before and after the start of the treatment, as well as the mean haemoglobin levels, number of admissions for anaemia due to gastrointestinal bleeding and length of hospital stay in these periods. RESULTS The mean age of patients included was 77.83 years old and 75% were male. The follow-up period after treatment initiation was 6 months. Of the 12 patients included, only one stopped the treatment owing to it not being effective. Overall, 83.3% of the patients reported subjective improvement. Furthermore, we found significant differences comparing before and after starting treatment regarding the mean number of transfusions (7±4.8 vs. 3.4±4.6; P=0.005), the mean haemoglobin levels (9.5±1.2 vs. 10.8±2.6; P=0.034) and the mean number of admissions (1.6±1.6 vs. 0.2±0.4; P=0.024). On the contrary, differences between pretreatment and post-treatment length of hospital stay were not significant. CONCLUSION Hormone therapy is a potentially useful therapeutic tool in patients with refractory bleeding and anaemia due to angiodysplasia.

Abstract
BACKGROUND Colonic angiodysplasia (AGD) is a common cause of gastrointestinal bleeding. However, information on the characteristics and prevalence of colonic AGD is limited. We determined the clinical features of and risk factors for active bleeding in colonic AGD in a Taiwanese population. METHODS From February 2007 to December 2016, 13,047 patients undergoing 16,760 colonoscopies at the Tri-Service General Hospital were included in this study. Eighty-four patients were diagnosed with AGD. We conducted a retrospective study by analyzing the medical records of these patients. The clinical features and endoscopic findings were evaluated. Furthermore, we distinguished colonic AGD into bleeding and non-bleeding types and identified the risk factors for bleeding in colonic AGD. RESULTS In our study, the prevalence of colonic AGD was 0.6% among all patients who received colonoscopy. Among patients with colonic AGD, we found that many were aged; in all, 58.3% of patients with colonic AGD were older than 65 years. More than half of the patients had hypertensive cardiovascular disease (53.6%) and the AGD lesions were predominantly located in the left-sided colon (41.7%). We analyzed several factors to identify those associated with bleeding colonic AGD. Our results indicated that age (p < 0.001), hypertension (p = 0.020), atrial fibrillation (p = 0.027), and in-patient status (p = 0.006) were significant factors associated with active bleeding lesions. On multivariate analysis, old age was the only significant risk factor. CONCLUSION Angiodysplastic lesions in Taiwanese patients were predominantly identified in the left-sided colon. Old age was an independent risk factor associated with active bleeding in colonic angiodysplasia.
