Contribution of Capsule Endoscopy Early in a Bleeding Episode to Treatment of Small Bowel Angioectasia: A Case Report. Medicina (B Aires) 2021; 57:medicina57040321. [PMID: 33807237 PMCID: PMC8067254 DOI: 10.3390/medicina57040321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 03/24/2021] [Accepted: 03/24/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Recent advances in endoscopic devices such as small bowel capsule endoscopy and balloon-assisted endoscopy have improved the level of medical care for small bowel bleeding. However, treating small bowel angioectasia remains challenging because repeated intermittent bleeding can occur from the multiple minute lesions (about 1 mm in size) that develop in a synchronous and metachronous manner. Here, we report a case of small bowel angioectasia in which capsule endoscopy performed early in a bleeding episode contributed to treatment. Case Summary: A 66-year-old man with suspected small bowel bleeding underwent small bowel capsule endoscopy and balloon-assisted endoscopy with argon plasma coagulation hemostasis for a small intestinal angioectasia. Because small bowel bleeding recurred intermittently after the treatment, small bowel capsule endoscopy and balloon-assisted endoscopy were repeated when there was no bleeding, but no abnormalities were found. Subsequent small bowel capsule endoscopy during a bleeding episode revealed bloody intestinal fluid in the proximal small intestine. Peroral balloon-assisted endoscopy was performed 2 days after SBCE for detailed observation of the small intestinal mucosa at the suspected bleeding site, and there a 1-mm Dieulafoy’s lesion with no active bleeding was identified. We performed argon plasma coagulation, and no bleeding was observed thereafter. Conclusions: Small bowel capsule endoscopy immediately after bleeding onset can identify the bleeding source of multiple minute lesions in small bowel angioectasia.

A Risk Assessment of Factors for the Presence of Angiodysplasias During Endoscopy and Factors Contributing to Symptomatic Bleeding and Rebleeds. Dig Dis Sci 2019; 64:2923-2932. [PMID: 31190204 PMCID: PMC6744377 DOI: 10.1007/s10620-019-05683-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Accepted: 05/23/2019] [Indexed: 12/25/2022]
Abstract
BACKGROUND Few studies have assessed factors associated with angiodysplasias during endoscopy or factors associated with symptomatic disease. AIMS To evaluate risk factors for the presence of and contribution to symptomatic disease in patients with angiodysplasias. METHODS We performed a systematic MEDLINE, EMBASE and Cochrane Library search according to the PRISMA guidelines for studies assessing risk factors involved in angiodysplasias detected during endoscopy and factors that lead to anemia or overt bleeding. Study quality was assessed with the Newcastle-Ottawa scale. A risk assessment was performed by selecting risk factors identified by two independent studies and/or by a large effect size. RESULTS Twenty-three studies involving 92,634 participants were included. The overall quality of the evidence was moderate. Risk factors for the diagnosis of angiodysplasias during endoscopy confirmed by at least two studies were increasing age (OR 1.09 per year, 95% CI 1.04-1.1), chronic kidney disease (OR 4.5, 95% CI 1.9-10.5) and cardiovascular disease (2.9, 95% CI 1.4-6.2). The risk of rebleeds was higher in the presence of multiple lesions (OR 4.2, 95% CI 1.1-16.2 and 3.8, 95% CI 1.3-11.3 and 8.6, 95% CI 1.4-52.6), liver cirrhosis (OR 4.0, 95% 1.1-15.0) and prothrombin time < 30% (OR 4.2, 95% 1.1-15.4) with a moderate effect size. Multiple comorbidities were associated with an increased in-hospital mortality (OR 2.29, 95% CI 1.2-4.3). CONCLUSIONS This systematic review identified age, chronic kidney disease and cardiovascular disease as the most important risk factors for the diagnosis of angiodysplasias during endoscopy. Multiple lesions increase the risk of recurrent bleeding.

Abstract
Objectives Balloon-assisted enteroscopy (BAE) is increasingly used for the evaluation of small bowel disorders. We quantified local diagnostic and therapeutic yields of BAE in patients with suspected small bowel diseases. Methods Adult patients undergoing BAE between January 2010 and July 2015 at McGill University Health Centre were included. Procedures were identified using a prospectively maintained database. Patients were excluded if procedure report was unavailable. Electronic medical records were reviewed. Analyses were restricted to patients who did not have a previous BAE. Results BAE was performed in 453 patients, including 421 anterograde cases. Patients had a mean age of 61.0 ± 17.5 years. Most common indications for referral were obscure gastrointestinal bleeding (OGIB) (n=207, 45.7%), abnormal imaging (n=88, 19.4%), suspected small bowel neoplasia (SBN) (n=39, 8.6%) and Crohn’s disease (CD) (n=31, 6.8%). A diagnosis was established in 216 procedures (47.7%). A pre-endoscopic indication of CD (odds ratio [OR]: 3.78; 95% Confidence Interval [CI], 1.60–8.90), OGIB (OR: 3.69, 95% CI, 2.03–6.71), suspected SBN (OR: 2.45; 95% CI, 1.06–5.65) and previous VCE (OR: 9.33; 95% CI, 3.24–26.90) were associated with abnormal findings. A therapeutic procedure was performed in 126 cases (28.3%). OGIB (OR: 7.00; 95% CI, 3.83–12.81), previous video capsule endoscopy (VCE) (OR: 7.86; 95% CI, 2.93–21.04) and suspected SBN (OR: 6.30; 95% CI, 2.58–21.04) were associated with performance of a therapeutic intervention. Complication rate was 1.6%, with bleeding in seven cases and one perforation. Conclusions In carefully selected patients, such as those with OGIB, Crohn’s disease and previous VCE, BAE was a safe procedure that led to the identification of abnormal findings and therapeutic interventions.

Abstract
Gastrointestinal angiodysplasia are rare but clinically important vascular aberrations found within the gastrointestinal mucosa and submucosa. Their clinical impact varies from being an asymptomatic incidental finding, to causing life threatening bleeding. In this review we critically appraise the key findings from the current literature on the pathology, clinical presentation and management of these lesions.

Abstract
GOAL We aimed to summarize pooled rebleeding rates of angioectasia after therapeutic endoscopy, and compare these to historical control (no intervention) rates. BACKGROUND Obscure gastrointestinal bleeding continues to be challenging to diagnose and treat; in America, small bowel angioectasias are the most common cause. Technology advances led to higher diagnostic yield for these lesions; however, therapeutic impact of endoscopy remains unclear. STUDY A PubMed search (June 1, 2006 to September 19, 2013) with 2 independent reviews sought articles reporting rebleeding rates of symptomatic angioectasia without therapy (natural history) and after endoscopic treatment. This study list was added to studies in the 2007 American Gastroenterological Association systematic review. Data on number of patients who underwent endoscopic therapy, type of therapy used, number of patients who experienced rebleeding, and follow-up time were extracted. Rebleeding data were pooled and weighted averages were reported with 95% confidence intervals (CI). RESULTS Twenty-four articles (n=490 patients) with data on endoscopic therapy for angioectasia and 6 natural history cohorts (n=130) receiving no therapy for angioectasia were eligible. Of the endoscopic therapy patients, 121 at push enteroscopy and 427 at balloon-assisted enteroscopy; 209/490 (42.7%; 95% CI, 38%-47%) rebled. Of the control (no therapy) patients, 64/130 (49.2%; 95% CI, 40%-58%) rebled. Number needed to treat is estimated at 15 to 16. CONCLUSIONS Rebleeding rate after endoscopic therapy for symptomatic small bowel angioectasia may be comparable to that expected without therapy. Endoscopic therapy may be ineffective; if effective, the needed to treat is estimated to be high. Controlled studies, with intervention-stratified and etiology-stratified outcomes are needed.

Abstract
Iron deficiency anemia is the most common type of anemia and can cause asthenia, cognitive and functional impairment, and decompensation of underlying diseases. Iron deficiency anemia is not a disease but is the result of a potentially serious medical problem. Consequently, patients should always undergo investigation of the underlying cause. In men and postmenopausal women, the condition is caused by gastrointestinal loss and malabsorption of iron. In this group, recommended procedures are gastroscopy, colonoscopy and serological testing for celiac disease. If the results of these tests are negative, repeat examinations and iron therapy should be considered. In treatment-refractory or recurrent anemia, the small intestine should be investigated. In this case, the procedure of choice is capsule endoscopy. Iron deficiency anemia should always be treated until iron deposits have returned to normal levels. A wide variety of preparations are available, in both oral and parental formulations.

Abstract
Upper gastrointestinal bleeding (UGIB) is the most common emergency condition in gastroenterology. Although peptic ulcer and esophagogastric varices are the predominant causes, other conditions account for up to 50% of UGIBs. These conditions, among others, include angiodysplasia, Dieulafoy and Mallory-Weiss lesions, gastric antral vascular ectasia, and Cameron lesions. Upper GI cancer as well as lesions of the biliary tract and pancreas may also result in severe UGIB. This article provides an overview of the endoscopic management of these lesions, including the role of novel therapeutic modalities such as hemostatic powder and over-the-scope-clips.

Abstract
BACKGROUND Small bowel angioectasia is reported as the most common cause of bleeding in patients with obscure gastrointestinal bleeding. Although the safety and efficacy of endoscopic treatment have been demonstrated, rebleeding rates are relatively high. To establish therapeutic and follow-up guidelines, we investigated the long-term outcomes and clinical predictors of rebleeding in patients with small bowel angioectasia. METHODS A total of 68 patients were retrospectively included in this study. All the patients had undergone CE examination, and subsequent control of bleeding, where needed, was accomplished by endoscopic argon plasma coagulation. Based on the follow-up data, the rebleeding rate was compared between patients who had/had not undergone endoscopic treatment. Multivariate analysis was performed using Cox proportional hazard regression model to identify the predictors of rebleeding. We defined the OGIB as controlled if there was no further overt bleeding within 6 months and the hemoglobin level had not fallen below 10 g/dl by the time of the final examination. RESULTS The overall rebleeding rate over a median follow-up duration of 30.5 months (interquartile range 16.5-47.0) was 33.8% (23/68 cases). The cumulative risk of rebleeding tended to be lower in the patients who had undergone endoscopic treatment than in those who had not undergone endoscopic treatment, however, the difference did not reach statistical significance (P = 0.14). In the majority of patients with rebleeding (18/23, 78.3%), the bleeding was controlled by the end of the follow-up period. Multiple regression analysis identified presence of multiple lesions (≥3) (OR 3.82; 95% CI 1.30-11.3, P = 0.02) as the only significant independent predictor of rebleeding. CONCLUSION In most cases, bleeding can be controlled by repeated endoscopic treatment. Careful follow-up is needed for patients with multiple lesions, presence of which is considered as a significant risk factor for rebleeding.

Abstract
In summary, small-intestine tumors are a rare phenomenon, but they are being discovered more frequently with newer diagnostic techniques. Prior studies of the small bowel were limited, making the diagnosis difficult. With the advent of CE and deep enteroscopy, gastroenterologists are finding these tumors at an earlier stage, thereby offering better management options for these patients. Although the incidence of small-bowel tumors has increased, the survival rates have remained the same. This may be a lag-time bias but could be a future area of research in this emerging field.

Management of gastrointestinal angiodysplastic lesions (GIADs): a systematic review and meta-analysis. Am J Gastroenterol 2014; 109:474-83; quiz 484.

Abstract
OBJECTIVES Gastrointestinal angiodysplastic lesions (GIADs) are defined as pathologically dilated communications between veins and capillaries. The objective of this systematic review and meta-analysis was to determine the efficacy of available treatment modalities for GIADs. METHODS We identified eligible studies by searching through PubMed, SCOPUS, and Cochrane central register of controlled trials. We searched for clinical trials examining the efficacy of endoscopic, pharmacologic, or surgical therapy for GIADs. Data were pooled using a random-effects model, and the effect of response to medical or surgical therapy was reported as odds ratios with 95% confidence intervals (CIs). Data and quality indicators were extracted by two authors from 22 studies, including 831 individuals with GIADs. The analysis included 623 patients treated with endoscopic therapy, 63 with hormonal therapy, 72 patients with octreotide, and 73 status post aortic valve replacement surgery. RESULTS Hormonal therapy, based on two case-control studies, was not effective for bleeding cessation (odds ratio: 1.0, 95% CI: 0.5-1.96). On the basis of 14 studies including patients with gastric, colonic, and small-bowel GIADs, endoscopic therapy was effective as initial therapy, but the pooled recurrence bleeding rate was 36% (95% CI: 28-44%) over a mean (±s.d.) of 22±13 months. The event rate for re-bleeding increased to 45% (95% CI: 37-52%) when studies including only small-bowel GIADs were included (N=341). In four studies assessing the efficacy of somatostatin analogs, the pooled odds ratio was 14.5 (95% CI: 5.9-36) for bleeding cessation. In two studies assessing the role of aortic valve replacement (AVR) in 73 patients with Heyde's syndrome, the event rate for re-bleeding was 0.19 (95% CI: 0.11-0.30) over a mean follow-up period of 4 years postoperatively. CONCLUSIONS Over one-third of patients with GIADs experienced re-bleeding after endoscopic therapy. Somatostatin analogs and AVR for Heyde's syndrome appeared to be effective therapy for GIADs.

Abstract
BACKGROUND Angiodysplasia (AD) of the gastrointestinal (GI) tract is an important condition that can cause significant morbidity and -rarely - mortality. AIM To provide an up-to-date comprehensive summary of the literature evaluating this disease entity with a particular focus on pathogenesis as well as current and emerging diagnostic and therapeutic modalities. Recommendations for treatment will be made on the basis of the current available evidence and consensus opinion of the authors. METHODS A systematic literature search was performed. The search strategy used the keywords 'angiodysplasia' or 'arteriovenous malformation' or 'angioectasia' or 'vascular ectasia' or 'vascular lesions' or 'vascular abnormalities' or 'vascular malformations' in the title or abstract. RESULTS Most AD lesions (54-81.9%) are detected in the caecum and ascending colon. They may develop secondary to chronic low-grade intermittent obstruction of submucosal veins coupled with increased vascular endothelial growth factor-dependent proliferation. Endotherapy with argon plasma coagulation resolves bleeding in 85% of patients with colonic AD. In patients who fail (or are not suitable for) other interventions, treatment with thalidomide or octreotide can lead to a clinically meaningful response in 71.4% and 77% of patients respectively. CONCLUSIONS Angiodysplasia is a rare, but important, cause of both overt and occult GI bleeding especially in the older patients. Advances in endoscopic imaging and therapeutic techniques have led to improved outcomes in these patients. The choice of treatment should be decided on a patient-by-patient basis. Further research is required to better understand the pathogenesis and identify potential therapeutic targets.

Abstract
Iron deficiency is the most frequent cause of anaemia worldwide. It impairs quality of life, increases asthenia and can lead to clinical worsening of patients. In addition, iron deficiency has a complex mechanism whose pathologic pathway is recently becoming better understood. The discovery of hepcidin has allowed a better clarification of iron metabolism regulation. Furthermore, the ratio of concentration of soluble transferrin receptor to the log of the ferritin level, has been developed as a tool to detect iron deficiency in most situations. The cause of iron deficiency should always be sought because the underlying condition can be serious. This review will summarize the current knowledge regarding diagnostic algorithms for iron deficiency anaemia. The majority of aetiologies occur in the digestive tract, in men and postmenopausal women, and justify morphological examination of the gut. First line investigations are upper gastrointestinal endoscopy and colonoscopy, and when negative, the small bowel should be explored; newer tools such as video capsule endoscopy have also been developed. The treatment of iron deficiency is aetiological if possible and iron supplementation whether in oral or in parenteral form. New parenteral formulations are available and seem to have promising results in terms of efficacy and safety.

Long-term outcomes after single-balloon enteroscopy in patients with obscure gastrointestinal bleeding. Dig Dis Sci 2013; 58:2572-9. [PMID: 23430372 PMCID: PMC3930755 DOI: 10.1007/s10620-013-2588-y] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2012] [Accepted: 01/24/2013] [Indexed: 12/13/2022]
Abstract
BACKGROUND Limited data exists on the long-term outcomes of patients with obscure gastrointestinal bleeding (OGIB) following single-balloon enteroscopy (SBE). AIM To examine the long-term outcomes of patients undergoing SBE for OGIB. METHODS Consecutive patients undergoing SBE for OGIB at a tertiary care center between 2008 and 2010 were retrospectively identified. Clinical data and SBE findings were extracted from the medical record. Recurrence of OGIB during follow-up through 2012 was assessed by a combination of chart review and telephone interviews. RESULTS One hundred and forty-seven patients were included in the study. The overall diagnostic yield of SBE was 64.6% (95/147 patients). Findings of SBE included vascular lesions (VLs, 53.7%), small bowel neoplasm (2.7%), inflammatory lesions (4.8%), and normal SBE (35.4%). One hundred and ten patients (56.4% female, mean age 70.6±11.3 years) were followed for an average 23.9 months after initial SBE. During follow-up, OGIB recurred in 39.5% of patients in whom a source of OGIB was identified on SBE and 55.9% of patients with normal findings on SBE. OGIB recurred in 47.6% of patients in whom small bowel VLs were treated endoscopically. None of the 13 patients in whom a non-VL lesion was identified as the source of bleeding on SBE experienced recurrent bleeding (p=0.019). CONCLUSIONS SBE is a safe and valuable method for managing patients with OGIB. More than 50% of patients experienced no recurrent bleeding during 2 years of follow-up after SBE. The long-term management of OGIB due to small bowel VLs remains challenging.

Lenz P, Domagk D. Double- vs. single-balloon vs. spiral enteroscopy. Best Pract Res Clin Gastroenterol 2012; 26:303-13.

Abstract
Starting with the introduction of the double-balloon enteroscope in 2001, two more techniques have been successfully developed for small bowel investigation (single-balloon enteroscopy, spiral enteroscopy). To compare the different enteroscopy systems, within this review, 68 studies were analyzed and put into context. The procedural characteristics (mean insertion depth, diagnostic yields, adverse events) were comparable for DBE, SBE or SE. The higher panenteroscopy rate in DBE might not have any clinical relevance. Therapeutic procedures, such as argon-plasma coagulation, polypectomy, dilation therapy and foreign body extraction are described with the DBE and SBE procedure. With regard to the present literature, the balloon-assisted devices as well as spiral enteroscopy technique seem to be equally suitable in clinical routine for imaging of the small bowel. The choice of the method should be based on availability, physicians' experience and clinical implications. Future randomized, controlled trials with large numbers of patients are needed to work out the subtleties of every single method.

Evaluating the role of small-bowel endoscopy in clinical practice: the largest single-centre experience. Eur J Gastroenterol Hepatol 2012; 24:513-9. [PMID: 22330235 DOI: 10.1097/meg.0b013e328350fb05] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/15/2022]
Abstract
OBJECTIVE There are few centres that offer all forms of small-bowel endoscopic modalities [capsule endoscopy (CE), push enteroscopy (PE), double-balloon enteroscopy (DBE) or single-balloon enteroscopy and intraoperative enteroscopy (IOE)]. Previous investigators have suggested that DBE may be more cost-effective as the first-line investigation. We evaluated the relationship among four modalities of small-bowel endoscopy in terms of demand, diagnostic yield, patient management and tolerability. METHODS Data were collected on patients who underwent PE and IOE since January 2002, CE since June 2002 and DBE since July 2006. These included age, sex, indication of referral, comorbidity, previous investigations and diagnosis obtained, including subsequent management change. RESULTS Demand for CE and DBE increased every year. A total of 1431 CEs, 247 PEs, 102 DBEs and 17 IOEs were performed over 93 months. The diagnostic yield was 88% for IOE compared with 34.6% for CE, 34.5% for PE and 43% for DBE (P<0.001). Management was altered by CE in 25%, by PE in 19% and by DBE in 33% of patients. However, 44% of patients who underwent DBE found the procedure difficult to tolerate. In 2009, for every 17 CEs performed, one patient underwent DBE locally. CONCLUSION This is the first series to report the clinical experience of four modalities of small-bowel endoscopy from a single centre. The use of CE as first-line investigation, followed by PE/DBE or IOE, is potentially both less invasive and tolerable.

Abstract
Small intestinal tumors are difficult challenge to gastroenterologists. The difficulty in making a diagnosis of small intestinal tumor lies in the relative inaccessibility and absence of typical presentation. New endoscopic and radiologic technologies provide clear and fine anatomical visualization of the small bowel and are approved to improve the diagnostic sensitivity and accuracy. Patients at risk of small intestinal tumors might gain a benefit from proper surveillance with this new technology. Minimally invasive therapy is now available with advance of balloon assisted enteroscopy. This review describes the general aspect of the small intestinal tumors, focusing on the new modalities for diagnosis.
