Clinical characteristics and risk factors for rebleeding in uremic patients with obscure gastrointestinal bleeding undergoing deep enteroscopy: A multi-center retrospective study in Taiwan. PLoS One 2022; 17:e0277434. [PMID: 36449459 PMCID: PMC9710796 DOI: 10.1371/journal.pone.0277434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Accepted: 10/26/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND/PURPOSE Recurrent obscure gastrointestinal bleeding (OGIB) in patients with chronic kidney disease is a challenge often faced by physicians, given the need for repeated hospitalizations, multiple extensive examinations, limited treatment options, and high medical costs. The purpose of this study was to identify the clinical characteristics of uremic patients undergoing deep enteroscopy for OGIB and analyze the risk factors for rebleeding in these patients after undergoing single-balloon enteroscopy (SBE). METHODS Out of 765 patients with OGIB who underwent 1004 procedures of SBE in four teaching hospitals, 78 uremic patients with OGIB were enrolled. Clinical characteristics and endoscopic findings were collected, and multiple variables were analyzed to determine the risk of rebleeding after SBE. RESULTS The diagnostic yield was 75.6%, and the rebleeding rate was 29.5% in the enrolled uremic patients. The most common etiology was angiodysplasia (74.6%) and the most common site was the jejunum (50.8%). The endoscopic intervention rate was 62.8% and most patients were treated with argon plasma coagulation (75.6%). Among the eight patients with valvular heart disease (VHD), four (50%) had severe aortic stenosis, and the remaining had non-aortic stenosis-VHD. VHD (p < 0.05) and angiodysplasia (p < 0.05) were both associated with a higher rebleeding rate. CONCLUSION VHD may be an independent risk factor associated with rebleeding after SBE in uremic patients with OGIB. Moreover, uremic patients with angiodysplasia-related bleeding appear to have a higher rebleeding rate than those with alternative causes of bleeding.

Front Med (Lausanne) 2022; 9:772954. [PMID: 35308514 PMCID: PMC8931682 DOI: 10.3389/fmed.2022.772954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 01/31/2022] [Indexed: 11/29/2022] Open
Abstract
Background For patients with obscure gastrointestinal bleeding (OGIB), finding the bleeding site is challenging. Balloon-assisted enteroscopy (BAE) has become the preferred diagnostic modality for OGIB. The long-term outcome of patients with negative BAE remains undefined. The present study aimed to evaluate the long-term outcomes of patients with negative BAE results for OGIB and to clarify the effect of further investigations at the time of rebleeding with a systematic review and meta-analysis of the available cohort studies. Methods Studies were searched through the PubMed, EMBASE, and Cochrane library databases. The following indexes were analyzed: rebleeding rate after negative BAE, rebleeding rate after different follow-up periods, the proportion of patients who underwent further evaluation after rebleeding, the percentage of patients with identified rebleeding sources, and the percentage of patients with rebleeding sources in the small intestine. Heterogeneity was assessed using the I2 test. Results Twelve studies that involved a total of 407 patients were included in the analysis. The pooled rebleeding rate after negative BAE for OGIB was 29.1% (95% CI: 17.2–42.6%). Heterogeneity was significant among the studies (I2 = 88%; p < 0.0001). The Chi-squared test did not show a difference in rebleeding rates between the short and long follow-up period groups (p = 0.142). The pooled proportion of patients who underwent further evaluation after rebleeding was 86.1%. Among the patients who underwent further evaluation, rebleeding sources were identified in 73.6% of patients, and 68.8% of the identified rebleeding lesions were in the small intestine. Conclusion A negative result of BAE in patients with OGIB indicates a subsequently low risk of rebleeding. Further evaluation should be considered after rebleeding.

Abstract
Background/Aims Single-balloon enteroscopy (SBE) has been widely used in diagnosing small bowel disease. We conducted this study to systematically appraise its technical and clinical performance. Methods Studies on SBE published by September 2018 were systematically searched. Technical and clinical performance data were collected and analyzed with descriptive or meta-analysis methods. Results In total, 54 articles incorporating 4,592 patients (6,036 procedures) were included. Regarding technical parameters, the pooled insertion depths (IDs) for anterograde and retrograde SBE were 209.2 cm and 98.1 cm, respectively. The pooled retrograde ID in Asian countries was significantly greater than that in Western countries (129.0 cm vs 81.1 cm, p<0.001). The pooled anterograde and retrograde procedure times were 57.6 minutes and 65.1 minutes, respectively. The total enteroscopy rate was 21.9%, with no significant difference between Asian and Western countries. Clinically, the pooled diagnostic yield of SBE was 62.3%. Obscure gastrointestinal bleeding (OGIB) was the most common indication (50.0%), with a diagnostic yield of 59.5%. Vascular lesions were the most common findings in Western OGIB patients (76.9%) but not in Asian ones (31.0%). The rates of severe and mild adverse events were 0.5% and 2.5%, respectively. Conclusions SBE is technically efficient and is clinically effective and safe, but total enteroscopy is relatively difficult to achieve with this technique. Etiologies of OGIB in Asian countries differ from those in Western countries.

Abstract
BACKGROUND/AIMS This study aimed to investigate the feasibility, efficiency, and clinical significance of examining the total gastrointestinal (GI) tract by consecutive bidirectional double-balloon enteroscopy (DBE) within 1 day in patients with suspected small-bowel bleeding. MATERIALS AND METHODS From January 2016 to January 2018, the clinical and endoscopic data of 41 patients with suspected small-bowel bleeding undergoing DBE aimed at inspecting the total GI tract within 1 day. RESULTS A success rate of 87.8% (36/41) for examining the total GI tract with no adverse event was achieved by consecutive bidirectional DBE performed within 1 day. The total examination time was 140.61±36.41 (range, 82-270) minutes. Positive or negative findings of bleeding were detected in 51.2% (21/41) and 48.8% (20/41) patients, respectively. Single bleeding etiology with non-small-bowel lesions (NSBLs) or small-bowel lesions (SBLs) was detected in 12.2% (5/41) and 26.8% (11/41) of patients, respectively. Dual bleeding etiologies, including NSBLs and SBLs, were detected in 12.2% (5/41) of patients. A re-bleeding rate of positive or negative findings was different (4.8% vs. 40.0%; p<0.05). CONCLUSION Consecutive bidirectional DBE within 1 day can achieve complete vision of the total GI tract with a considerable success rate and high safety. This strategy may provide an option for detecting bleeding etiology throughout the GI tract. A negative finding with this method cannot absolutely exclude missed bleeding etiology and re-bleeding.

Abstract
The small bowel had long been considered a dark unapproachable tunnel until the invention of capsule endoscopy and doubleballoon enteroscopy in the 21st century, which revolutionized the diagnosis and management of small bowel diseases, including bleeding. Various imaging modalities such as computed tomographic enterography, angiography, capsule endoscopy, and balloonassisted enteroscopy play vital roles in the diagnosis and management of small bowel bleeding. The choice of modality to use and timing of application differ according to the availability of the modalities, patient’s history, and physician’s experience. Small bowel bleeding is managed using different strategies as exemplified by medical treatment, interventional radiology, endoscopic therapy, or surgical intervention. Balloon-assisted enteroscopy enables endoscopic interventions to control small bowel bleeding, including electrocautery, argon plasma coagulation, clip application, and tattooing as a prelude to surgery. In this article, we clarify the recent approaches to the optimal diagnosis and management of patients with small bowel bleeding.

Abstract
BACKGROUND data on the long-term outcome of patients with obscure gastrointestinal bleeding (OGIB) with positive small bowel findings in capsule endoscopy but negative small bowel findings in device-assisted enteroscopy are scarce. OBJECTIVE this study aimed to evaluate the rebleeding rate and time to rebleed in patients with no small bowel findings in enteroscopy, after a positive capsule endoscopy in the setting of OGIB. Baseline predictors for rebleeding were assessed. METHODS a retrospective double-center study was performed, including patients with OGIB with positive findings by capsule endoscopy and negative small bowel findings by enteroscopy. RESULTS thirty-five patients were included. Rebleeding occurred in 40 % of patients during a median follow-up of 27 months. Further evaluation in patients with a rebleed was performed in 85.7 %, leading to a final diagnosis in 78.6 %. The rebleeding rate increased progressively over time, from 17.2 % at one month to 54.4 % at four years. Overt bleeding at the time of the first episode was a predictor of rebleeding (p = 0.03) according to the multivariate analysis. This was 50 % at one year compared with 21.8 % in patients with occult bleeding on admission. CONCLUSIONS in obscure gastrointestinal bleeding, long-term follow-up and further evaluation may be considered after a positive capsule endoscopy. Even if there are no small bowel findings by device-assisted enteroscopy. The rebleeding rate in our study was 40 %, mainly in the presence of an overt bleeding on admission.

Abstract
Small-bowel bleeding accounts for the majority of obscure gastrointestinal bleeding, but it is caused by various types of small bowel disease, upper gastrointestinal disease, and colorectal disease. For the diagnosis, history taking and physical examination are required, leading to a determination of what diseases are involved. Next, cross-sectional imaging, such as computed tomography, should be carried out, followed by the latest enteroscopy such as small bowel capsule endoscopy and deep enteroscopy according to the severity of hemorrhage and patient condition. After a comprehensive diagnosis, medical, enteroscopic, or surgical treatment should be selected. This article reviews recent advances in the endoscopic diagnosis of obscure gastrointestinal bleeding and compares perspectives of the management of obscure gastrointestinal bleeding in Japan with that in other countries.

Abstract
BACKGROUND AND AIMS Single-balloon enteroscopy (SBE) is utilized in the evaluation of obscure gastrointestinal bleeding, but 40-50% of these patients experience continued GI blood loss, in part due to missed lesions. The utilization of a transparent cap attached to the end of the endoscope can improve mucosal visualization in other endoscopic applications, but has not yet been evaluated in SBE. The aim of this study was to evaluate the impact of a cap on the diagnostic yield of SBE. METHODS Consecutive adult patients scheduled for anterograde SBE for the evaluation of obscure GI bleeding were screened for inclusion from 2014 to 2017. Patients were randomized to SBE with or without a transparent cap. The primary outcome was the proportion of enteroscopies in which a P2 lesion (high potential for bleeding) was identified. RESULTS A total of 90 patients (65.7 ± 12.7 years old, 47.7% female) were analyzed. There were significantly more P2 arteriovenous malformations identified in the cap group (14.8% vs. 0%, p = 0.02). Additionally, the use of a cap was associated with a significantly greater depth of small bowel insertion (191.9 cm vs. 156.2 cm, p = 0.01). There was one perforation in the group without a cap, successfully treated with clip placement, and no adverse events in the cap group. CONCLUSIONS The use of a transparent cap during SBE performed for the evaluation of obscure gastrointestinal bleeding may be an important, safe augmentation to standard SBE techniques.

Abstract
Small bowel vascular lesions, including angioectasia (AE), Dieulafoy’s lesion (DL) and arteriovenous malformation (AVM), are the most common causes of obscure gastrointestinal bleeding. Since AE are considered to be venous lesions, they usually manifest as a chronic, well-compensated condition. Subsequent to video capsule endoscopy, deep enteroscopy can be applied to control active bleeding or to improve anemia necessitating blood transfusion. Despite the initial treatment efficacy of argon plasma coagulation (APC), many patients experience re-bleeding, probably because of recurrent or missed AEs. Pharmacological treatments can be considered for patients who have not responded well to other types of treatment or in whom endoscopy is contraindicated. Meanwhile, a conservative approach with iron supplementation remains an option for patients with mild anemia. DL and AVM are considered to be arterial lesions; therefore, these lesions frequently cause acute life-threatening hemorrhage. Mechanical hemostasis using endoclips is recommended to treat DLs, considering the high re-bleeding rate after primary APC cauterization. Meanwhile, most small bowel AVMs are large and susceptible to re-bleeding therefore, they usually require surgical resection. To achieve optimal diagnostic and therapeutic approaches for each type of small bowel lesion, the differences in their epidemiology, pathology and clinical presentation must be understood.

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.

Early timing of single balloon enteroscopy is associated with increased diagnostic yield in patients with overt small bowel bleeding. J Formos Med Assoc 2019; 118:1644-1651.

Abstract
BACKGROUND/PURPOSE Although performing balloon enteroscopy soon after the onset of small bowel bleeding appeared to enhance diagnostic rate, the optimal timing was unclear. METHODS A retrospective cohort study in a single referral center. Patients with overt, suspected small bowel bleeding who underwent primary single-balloon enteroscopy (SBE) were evaluated to determine the association between procedure timing and diagnostic yield rates. RESULTS A total of 220 patients were enrolled (47.7% males; mean age, 65.6 ± 18.1 years). They were stratified into four groups based on the timing of SBE: emergency (<24 h after onset or continued bleeding, n = 64), 24-72 h (n = 28), 3-7 days (n = 41), and >7 days (n = 87). A significant trend of decreasing diagnostic yields was observed across the groups (90.6%, 67.9%, 68.3%, and 44.8%, respectively, P < 0.0001). Diagnostic yield rates were different between emergency and 24-72 h groups (P < 0.0001), and between 3 and 7 days and >7 days groups (P < 0.05), but not between 24 and 72 h and 3-7 days groups (P = 0.97). In multivariate regression analysis, emergency, ≤ 3 days, and ≤7 days SBEs had greater yield rates than SBEs at later timings. CONCLUSION The likelihood of diagnostic yield was highest when SBE was performed during continued bleeding or within 24 h of onset, and gradually declined as waiting time increased. We therefore recommend that SBE should be performed as soon as possible, preferably no later than seven days.

Yang CW, Chen HW, Chen BC, Chen PJ, Shih YL, Chang WK, Hsieh TY, Huang TY. Is a bleeding scan prior to single-balloon enteroscopy necessary in patients with obscure gastrointestinal bleeding? J Formos Med Assoc 2018; 118:1031-1037. [PMID: 30473414 DOI: 10.1016/j.jfma.2018.11.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Revised: 10/20/2018] [Accepted: 11/07/2018] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND/PURPOSE To evaluate the efficacy and accuracy of bleeder localization in a pre-enteroscopic bleeding scan in patients with obscure gastrointestinal bleeding (OGIB). METHODS From January 2009 to December 2014, 98 patients with OGIB undergoing single-balloon enteroscopy (SBE) were enrolled. These patients were classified based on their history of a previous bleeding scan; 56 patients had undergone a previous bleeding scan, whereas 42 had not. The clinical characteristics, endoscopic findings, and rebleeding rate were compared between these two groups. The ability of the bleeding scan to localize the bleeding site was analyzed. RESULTS The mean age of patients was 56 ± 22 years; final diagnostic yield, 65.3%; and the most common etiology of OGIB, angiodysplasia (29.6%). There was no significant difference in demographic characteristics, OGIB etiologies, and final diagnostic yields (67.9% vs. 61.2%, bleeding scan vs. control group) between groups. In the bleeding scan group, the rate of positive detection was approximately 80.4%. However, only 26.7% patients with a positive bleeding scan showed correct localization of bleeding. Moreover, the bleeding scan delayed SBE (8.9 days vs. 3.0 days, p < 0.001). During the 24 months of follow-up, 15 patients (15.3%) exhibited rebleeding and needed to be hospitalized, but there was no significant difference between the groups. CONCLUSION In our study, bleeding scans in patients with OGIB revealed poor localization of the bleeder and delay in performing SBE. Thus, a bleeding scan prior to SBE showed a limited role for patients with OGIB.

Abstract
BACKGROUND Most studies have focused on evaluating the association between the presence of small bowel vascular lesions (SBVLs) and patients' comorbidities. AIMS We sought to uncover a more fundamental indicator that may predict the presence of SBVLs by considering atherosclerosis qualitatively and quantitatively. METHODS We enrolled 79 consecutive patients with obscure gastrointestinal bleeding who had undergone computed tomography (CT) and capsule endoscopy or double-balloon endoscopy from January 2015 to June 2017. The SBVL frequency, type, and location, and the relationship between the presence of SBVLs and the patients' clinical characteristics were evaluated. Arterial wall calcification was assessed on unenhanced CT images, and a modified Agatston scoring system was used to determine the abdominal aorta calcium scores. RESULTS Of the 27 (34%) patients with SBVLs, 15 (19%) had type 1a, 12 (15%) had type 1b, and 2 (3%) had type 2a SBVLs. Most of the lesions were located in the jejunum. Cardiovascular disease (P = .017), chronic kidney disease (P = .025), and arteriosclerosis (P = .0036) were associated with the presence of SBVLs. Subsequent multivariate analysis revealed that arteriosclerosis (odds ratio [OR] 7.29; 95% confidence interval [CI] 1.13-143.9) and superior mesenteric artery calcification (OR 16.3; 95% CI 3.64-118.6) were independent predictors of the presence of SBVLs. The modified Agatston score was significantly higher in SBVL cases than in non-SBVL cases (6384 vs. 2666, P = .0023). CONCLUSIONS Arteriosclerosis, especially increased superior mesenteric artery calcification, is associated with an increased likelihood of SBVLs.

Abstract
Management of small bowel diseases has evolved since the advent of capsule endoscopy (CE) and balloon-assisted enteroscopy (BAE). One of the most common indications for enteroscopy is obscure gastrointestinal bleeding (OGIB), followed by small bowel stenosis, tumors, and inflammatory bowel disease. Although enteroscopes have been regarded as useful tools, correct guidelines are required to ensure that we manipulate these enteroscopes safely and efficiently in clinical practice. Herein, the Japanese Gastroenterological Endoscopy Society has developed 'Clinical Practice Guidelines for Enteroscopy' in collaboration with the Japanese Society of Gastroenterology, the Japanese Gastroenterological Association, and the Japanese Association for Capsule Endoscopy. These guidelines are based on the evidence available until now, but small bowel endoscopy is a relatively new technology, so the guidelines include recommendations based on a consensus reached among experts when the evidence has not been considered sufficient. These guidelines were not designed to be disease-based, but focus on how we should use small bowel CE and BAE in everyday clinical practice.

Abstract
Gastrointestinal angiodysplasia (GIAD) are red flat arborized lesions that are found throughout the entire gastrointestinal tract. GIAD can vary in size and have a range of presentation from occult to life-threatening bleeding. The typical presentation is intermittent bleeding in the setting of iron deficiency anemia. Endoscopy is the primary means of diagnosis and endoscopic therapy is noted to be initially effective. However, rebleeding can be as high as 40% to 50% in patients with small bowel GIAD. This review describes the pathophysiology for the development of GIAD and the current roles of endoscopic, medical, and surgical therapy in its treatment.

Abstract
BACKGROUND The development of balloon assisted enteroscopy (BAE) has revolutionized diagnostic and therapeutic modalities for small-bowel disorders. Although the role of emergent esophagogastroduodenoscopy and colonoscopy for upper and lower gastrointestinal bleeding is well defined, there is scarce data with regard to emergent BAE for gastrointestinal bleeding. STUDY We performed a retrospective cohort study including 110 hospitalized patients with obscure gastrointestinal bleeding who underwent single balloon enteroscopy (SBE) between January 2010 and August 2013. Patients were divided into two groups based on procedures performed emergently (within 24 hours) versus non-emergently (greater than 24 hours). Data on patient demographics, hemodynamic characteristics, type of obscure bleed, lesions identified, location of lesions, endoscopic intervention performed, need for further surgical or radiological intervention, diagnostic and therapeutic yield, and adverse events were compared between groups. Independent samples t test and Fisher's exact test were used to assess the association between dependent and independent variables. For continuous data, the results were summarized as mean difference and 95 % confidence intervals (CI), and for binary as odds ratio and 95 %CI. RESULTS Although patients in the group where enteroscopy was performed within 24 hours had a significantly higher incidence of radiological intervention (10.0 % vs. 0.0 %, P = 0.019), the diagnostic and therapeutic yields between the two groups were not significantly different. Additionally, there were no statistically significant differences between the groups for overt and occult bleeding, transfusion requirements, type and location of lesions, endoscopic intervention performed, or adverse events. Hospital stay was shorter in the patients who had SBE within 24 hours of admission (6.2 vs. 11.3 days, P < 0.001). CONCLUSIONS Although the diagnostic and therapeutic yields of SBE were not significantly different between patients having the procedure within 24 hours and those having it later, the early SBE group required more interventional radiology procedures. While endoscopists may not necessarily have to perform emergent assessment within 24 hours in patients with obscure gastrointestinal bleeding (OGIB) for greater diagnostic or therapeutic yield, early intervention may allow for earlier stabilization and thus shorter hospital stays. Prospective studies further evaluating these findings are indicated.

Abstract
AIM: To assess whether video capsule endoscopy (VCE) affects the outcomes of left ventricular assist devices (LVADs) recipients with gastrointestinal bleeding.
METHODS: This is a retrospective study of LVAD recipients with obscure gastrointestinal bleeding (OGIB) who underwent VCE at a tertiary medical center between 2005 and 2013. All patients were admitted and monitored with telemetry and all VCE and subsequent endoscopic procedures were performed as inpatients. A VCE study was considered positive only when P2 lesions were found and was regarded as negative if P1 or P0 were identified. All patients were followed until heart transplant, death, or the end of the study.
RESULTS: Between 2005 and 2013, 30 patients with LVAD underwent VCE. Completion rate of VCE was 93.3% and there was no capsule retention. No interference of VCE recording or the function of LVAD was found. VCE was positive in 40% of patients (n = 12). The most common finding was active small intestinal bleeding (50%) and small intestinal angiodysplasia (33.3%). There was no difference in the rate of recurrent bleeding between patients with positive and negative VCE study (50.0% vs 55.6%, P = 1.00) during an average of 11.6 ± 9.6 mo follow up. Among patients with positive VCE, the recurrent bleeding rate did not differ whether subsequent endoscopy was performed (50% vs 50%, P = 1.00).
CONCLUSION: VCE can be safely performed in LVAD recipients with a diagnostic yield of 40%. VCE does not affect recurrent bleeding in LVAD patients regardless of findings.

Abstract
BACKGROUND AND AIMS The effectiveness of endoscopic therapy of small-bowel vascular lesions (SBVL) remains unclear as recent studies report high recurrence rates after 2 years of follow-up. This study aimed to evaluate the long-term rebleeding risk after endoscopic therapy of SBVL and to identify predictive factors of rebleeding. METHODS This was a retrospective single-center series of patients with SBVL treated endoscopically between July 2007 and February 2015. Relevant data from patient files, capsule endoscopies, and enteroscopy reports were retrieved. The primary endpoint was long-term rebleeding and the secondary endpoints were risk factors for rebleeding and transfusion requirements. RESULTS Thirty-five patients were included. Capsule endoscopies indicated angioectasias in 74.3% and blood in the remaining; angioectasias were found in 97.1% of enteroscopies. Rebleeding occurred in 40% of patients during a median follow-up of 23 months (interquartile range 9-43). The rebleeding rate at 1, 2, 3, 4, and 5 years was 32.7, 38.3, 46.0, 53.7, and 63.0%, respectively. Only the presence of high-risk comorbidities (aortic valve stenosis, chronic renal or liver disease, or Osler-Weber-Rendu syndrome) was associated with higher rebleeding (P=0.006) in the univariate and multivariate analyses, being 51.3%/67.6% at 1/3 years, compared with 6.7%/22.2% in patients without any of these comorbidities. Transfusion requirements decreased to 6.3 (0.0-6.0) packed red blood cells units the year after endoscopic therapy compared with 11.5 (2.0-17.0) in the previous year (P=0.002). CONCLUSION More than half of the patients had rebleeding after 5 years of follow-up, although transfusion requirements decreased. Patients with high-risk comorbidities are more likely to rebleed.

Abstract
BACKGROUND Single balloon enteroscopy (SBE) is an important tool in the management of small bowel disease with limited data available on its performance in the elderly. We aimed to evaluate the safety, efficacy, diagnostic and therapeutic outcomes of SBE in the elderly. METHODS A retrospective review was performed on 366 patients undergoing 428 SBEs from 2010 to 2014. Patients were divided into different age groups: control <55, 55-64, 65-74 and ⩾75 years. Data on comorbidities, complications, findings, diagnostic and therapeutic yield were compared between groups. RESULTS Anterograde and retrograde SBE were performed in 340 and 49 patients, respectively, with 63 patients requiring more than 1 procedure. Diagnostic yield was significantly higher for age ⩾75 years compared with <55, 66.3% versus 50%, odds ratio (OR) 1.97 [95% confidence interval (CI) 1.14-3.41]. Therapeutic yield was significantly higher in all three older age groups compared with <55 years, 20.3%: 55-64 years, 44.4%, OR 3.13(95% CI 1.7-5.78); 65-74 years, 42%, OR 2.84 (95% CI 1.59-5.06); and >75 years, 47.5%, OR 3.55 (95% CI 1.96-6.43). No significant difference was seen between age groups in complications or failures. Our overall complication rate was 2.3% with 5 minor and 5 major complications. There was a higher yield of angioectasias in the elderly. Argon plasma coagulation (APC) and multipolar electrocoagulation were used more often in older age groups. CONCLUSION SBE is safe in elderly patients and delivers higher diagnostic and therapeutic yields compared to younger patients. The elderly are more likely to have angioectasias and undergo APC and electrocoagulation.

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
Bleeding from the small intestine remains a relatively uncommon event, accounting for ~5-10% of all patients presenting with gastrointestinal (GI) bleeding. Given advances in small bowel imaging with video capsule endoscopy (VCE), deep enteroscopy, and radiographic imaging, the cause of bleeding in the small bowel can now be identified in most patients. The term small bowel bleeding is therefore proposed as a replacement for the previous classification of obscure GI bleeding (OGIB). We recommend that the term OGIB should be reserved for patients in whom a source of bleeding cannot be identified anywhere in the GI tract. A source of small bowel bleeding should be considered in patients with GI bleeding after performance of a normal upper and lower endoscopic examination. Second-look examinations using upper endoscopy, push enteroscopy, and/or colonoscopy can be performed if indicated before small bowel evaluation. VCE should be considered a first-line procedure for small bowel investigation. Any method of deep enteroscopy can be used when endoscopic evaluation and therapy are required. VCE should be performed before deep enteroscopy if there is no contraindication. Computed tomographic enterography should be performed in patients with suspected obstruction before VCE or after negative VCE examinations. When there is acute overt hemorrhage in the unstable patient, angiography should be performed emergently. In patients with occult hemorrhage or stable patients with active overt bleeding, multiphasic computed tomography should be performed after VCE or CTE to identify the source of bleeding and to guide further management. If a source of bleeding is identified in the small bowel that is associated with significant ongoing anemia and/or active bleeding, the patient should be managed with endoscopic therapy. Conservative management is recommended for patients without a source found after small bowel investigation, whereas repeat diagnostic investigations are recommended for patients with initial negative small bowel evaluations and ongoing overt or occult bleeding.

Abstract
Small-bowel bleeding comprises a majority of obscure gastrointestinal bleeding, but is caused by various kinds of diseases. For its diagnosis, history-taking and physical examination is requisite, leading to a suspicion of what diseases are involved. Next, cross-sectional imaging such as computed tomography should be done, followed by the latest enteroscopy, videocapsule endoscopy and deep enteroscopy according to the severity of hemorrhage and patient conditions. After comprehensive diagnosis, medical, enteroscopic, or surgical treatment should be selected.

Capsule endoscopy followed by single balloon enteroscopy in children with obscure gastrointestinal bleeding: a combined approach. Dig Liver Dis 2015; 47:125-30. [PMID: 25266487 DOI: 10.1016/j.dld.2014.09.001] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2014] [Revised: 08/16/2014] [Accepted: 09/02/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND This prospective single-centre study aims to evaluate a new diagnostic algorithm using capsule endoscopy, colon capsule endoscopy and single-balloon enteroscopy in the work-up of obscure gastrointestinal bleeding in children. METHODS The usefulness of a new diagnostic algorithm was assessed comparing the clinically relevant findings revealed by each technique, and evaluating the clinical outcomes during the follow-up. RESULTS A total of 22 paediatric patients were evaluated (14 male; mean age 12.5 years ± 3.9). Capsule endoscopies were positive in 14 (63.6%), suspicious in 5 (22.7%) and negative in 3 (13.6%). A second look with colon capsule identified new lesions in 2/3 (67%) of previous negative cases. Enteroscopies were able to reach the positive and suspicious findings in all but 2, in which an intraoperative enteroscopy was needed. This combined approach showed positive findings in 21/22 of cases with a diagnostic yield of 95%. Eighteen patients (82%) had a complete resolution after therapy. One patient resolved his symptoms spontaneously. Despite diagnosis, in three patients (13.6%) the gastrointestinal bleeding was not resolved after therapy. CONCLUSION This algorithm achieves optimal levels of diagnostic yield (95%) and therapeutic outcome (82%). This approach deserves to be studied in a larger multicentre cohort of patients and for a longer follow-up period.

Abstract
AIM: To investigate the diagnostic value of single balloon endoscopy (SBE) in obscure gastrointestinal bleeding (OGIB).
METHODS: Clinical data for 115 patients with OGIB who underwent SBE from July 2009 to May 2013 were retrospectively analyzed. The causes of gastrointestinal bleeding were observed by SBE. Eleven patients underwent endoscopic therapy.
RESULTS: The detection rate of gastrointestinal bleeding was 73.91% (85/115). The most common reasons for OGIB were small intestinal ulcer, small intestinal diverticulum, mucosal inflammatory changes, interstitialoma, small intestine carcinoma, Crohn's disease, small intestinal polyps, vascular dilatation, and other rare diseases. Seventy-eight (67.83%) patients had overt bleeding, and 37 (32.17%) had occult bleeding. The detection rate of overt bleeding was significantly higher than that of occult bleeding (P < 0.05).
CONCLUSION: SBE has high diagnostic yield in OGIB, and is a safe and reliable method for diagnosis and treatment of OGIB. The most common reasons for OGIB are small intestinal ulcer, small intestinal diverticulum, and mucosal inflammatory changes.

Abstract
AIM: To compare the clinical application value of single balloon enteroscopy (SBE) and double balloon enteroscopy (DBE).
METHODS: Clinical data for 720 subjects who underwent enteroscopy (510 cases of SBE and 210 cases of DBE) from January 2007 to September 2012 were retrospectively analyzed. Procedure duration, intubation depth, diagnostic yield and endoscopic treatment rate were compared between the two groups.
RESULTS: No significant difference was found between the two groups in procedure duration (SBE 54.41 min ± 11.742 min vs DBE 54.94 min ± 12.315 min for the oral approach, SBE 64.71 min ± 12.359 min vs DBE 65.81 min ± 13.995 min for the anal approach), intubation depth (SBE 235.12 cm ± 87.831 cm vs DBE 219.94 cm ± 68.226 cm for the oral approach, SBE 187.75 cm ± 67.037 cm vs DBE 172.37 cm ± 81.808 cm for the anal approach), diagnostic yield (SBE 77.05% vs DBE 75.67% for the oral approach, SBE 70.18% vs DBE 76.77% for the anal approach) or endoscopic treatment rate (SBE 46.58% vs DBE 48.85% for the oral approach, SBE 35.32% vs DBE 33.33% for the anal approach).
CONCLUSION: SBE and DBE have comparable performance and diagnostic yield in the evaluation of the small bowel. SBE is an effective method for the diagnosis and treatment of small bowel diseases.
