Selvanderan S, Noguchi M, Banh X, Ket S, Brown G. Yield of capsule endoscopy and subsequent device-assisted enteroscopy: Experience at an Australian tertiary centre. Intern Med J 2024. [PMID: 38567663 DOI: 10.1111/imj.16385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 03/13/2024] [Indexed: 04/04/2024]
Abstract
BACKGROUND Small bowel capsule endoscopy (SBCE) and device-assisted enteroscopy (DAE) have an established role in the investigation and management of small bowel pathology. Previous studies have reported on the yield of SBCE (60%) and DAE (57%), but none have been in an Australian setting. AIMS To determine the yield of SBCE and any DAE performed as a direct consequence of SBCE in an Australian referral centre. METHODS A single-centre retrospective study was conducted at a tertiary hospital in Australia, enrolling consecutive patients between 1 January 2009 and 31 December 2021 undergoing SBCE. Data were collected with respect to demographics, procedural factors and findings, as well as findings and interventions of any DAE procedures performed after the SBCE. RESULTS 1214 SBCEs were performed, with a median age of 66 years old (60.8% men). The predominant indications were anaemia (n = 853, 70.2%) and overt gastrointestinal bleeding (n = 320, 26.4%). Of the complete small bowel studies (1132/1214, 93.2%), abnormal findings were detected in 588 cases (51.9%), most commonly angioectasias (266/588, 45.2%), erosions (106/588, 18.0%) and ulcers (97/588, 8.6%). 165 patients underwent a DAE (117 antegrade, 48 retrograde). Antegrade DAE had a higher yield than retrograde DAE (77.8% vs 54.2%; P = 0.002) and a higher rate of intervention (69.2% vs 37.5%; P < 0.001). CONCLUSION In this largest single-centre cohort of patients undergoing SBCE to date, there is a similar yield of abnormal findings compared to existing literature. DAE, especially with an antegrade approach, had high diagnostic and therapeutic yield when pursued after a positive SBCE study.

Abstract
BACKGROUND AND AIMS The incidence of rebleeding in obscure GI bleeding (OGIB) remains unclear. This study used capsule endoscopy (CE) to determine the long-term rebleeding rate and predictive factors for rebleeding in patients with OGIB. METHODS This single-center, observational study enrolled consecutive patients with OGIB who underwent CE as the first small intestinal examination between March 2004 and December 2015 and were followed up through medical records or letters. RESULTS Three hundred eighty-nine patients were included in the analysis. Survival curve analysis showed that the overall cumulative rebleeding rate in OGIB during the 5 years was 41.7%. Multivariate analysis using the Cox proportional hazards model revealed that overt OGIB (hazard ratio [HR], 2.017; 95% confidence interval [CI], 1.299-3.131; P = .002), anticoagulants (HR, 1.930; 95% CI, 1.093-3.410; P = .023), positive balloon-assisted enteroscopy findings after CE (HR, 2.927; 95% CI, 1.791-4.783; P < .001), and iron supplements without therapeutic intervention (HR, 2.202; 95% CI, 1.386-3.498; P = .001) were associated with rebleeding, whereas a higher minimum hemoglobin level (HR, .902; 95% CI, .834-.975; P = .009) and therapeutic intervention (HR, .288; 95% CI, .145-.570; P < .001) significantly reduced the risk of rebleeding. Among the Charlson Comorbidity Index components, liver cirrhosis was an independent predictor associated with rebleeding in patients with OGIB (HR, 4.362; 95% CI, 2.622-7.259; P < .001) and in patients with negative CE findings (HR, 8.961; 95% CI, 4.424-18.150; P < .001). CONCLUSIONS Rebleeding is common during the long-term follow-up of patients with OGIB. Careful follow-up is required for patients with liver cirrhosis or previous massive bleeding.

Abstract
Observing the entire small bowel is difficult due to the presence of complex loops and a long length. Capsule endoscopy (CE) provides a noninvasive and patient-friendly method for visualizing the small bowel and colon. Small bowel capsule endoscopy (SBCE) has a critical role in the diagnosis of small bowel disorders through the direct observation of the entire small bowel mucosa and is becoming the primary diagnostic tool for small bowel diseases. Recently, colon capsule endoscopy (CCE) was also considered safe and feasible for obtaining sufficient colonic images in patients with incomplete colonoscopy, in the absence of bowel obstruction. This review article assesses the current status of CE in terms of the diagnostic yield and the clinical impact of SBCE in patients with obscure gastrointestinal bleeding, who have known or suspected Crohn's disease, small bowel tumor and inherited polyposis syndrome, celiac disease, and those who have undergone CCE.

Abstract
Video capsule endoscopy has an essential role in the diagnosis and management of small bowel bleeding and is the first-line study recommended for this purpose. This article reviews the risk factors for small bowel bleeding, optimal timing for video capsule endoscopy testing, and algorithms recommended for evaluation. Used primarily for the assessment of nonacute gastrointestinal blood loss, video capsule endoscopy has an emerging role for more urgent use in emergency settings and in special populations. Future software incorporation of neural networks to enhance lesion detection will likely result in an augmented role of video capsule endoscopy in small bowel bleeding.

Abstract
BACKGROUND AND AIMS The diagnostic yield (DY) and therapeutic yield (TY) of balloon-assisted enteroscopy (BAE) in overt obscure gastrointestinal bleeding (OGIB) is higher in the first 72 h. This study aimed to evaluate if this higher DY and TY after urgent BAE impacted the rebleeding rate, time to rebleed and short-term mortality. METHODS Retrospective cohort-study, which consecutively included all patients submitted to BAE for overt OGIB, between 2010 and 2019. Patients were distributed in 2 groups: (1) Urgent BAE; (2) Non-urgent BAE. Rebleeding was defined as an Hb drop >2 g/dL, need for transfusional support or presence of melena/hematochezia. RESULTS Fifty-four patients were included, of which 17 (31.5%) were submitted to BAE in the first 72 h. DY and TY of urgent BAE (DY 88.2%; n = 15; TY 94.1%; n = 16) was higher compared to non-urgent BAE (DY 59.5%; n = 22; TY 45.9%; n = 17) (DY p = .03) (TY p = .001). The rebleeding rate at 1, 2, and 5 years was 32.0%, 34.0%and 37.0%, respectively. Rebleeding was lower after urgent BAE (17.6%; n = 3) compared to non-urgent BAE (45.9%; n = 17) (p = .04). Rebleeding tended to occurr earlier in non-urgent BAE, being at 6-months (32.5%) and 36 months (41.3%) (p = .05). OGIB related 30-day mortality was 5.4% (n = 2) for non-urgent BAE and 0% for urgent BAE (p = .5). CONCLUSION Urgent BAE might be associated with higher DY and TY with lower rebleeding and trend toward higher rebleeding-free time.

Abstract
Despite the extensive recent development of different techniques for endoscopic evaluation for both diagnostic and therapeutic reasons, the small bowel remains quite difficult to visualize. Capsule endoscopy and device assisted enteroscopy are presently considered the best diagnostic tools for examination of small bowel disorders, assessing diverse pathologies such as obscure gastrointestinal bleeding, iron deficiency anemia, Crohn disease, small bowel tumors and polyposis syndromes. Like any other imagistic method, it has specific indications, and contraindications, and possibly it is more important to consider limitations. In order to obtain a better result, it is necessary to respect the procedural quality indicators. Among them the use of prokinetics - diverse pharmacological substances increasing the success rate of capsule endoscopy have raised debates. Capsule endoscopy small bowel evaluation is a reliable, non-invasive and safe with many advantages and minimum risks, with a proper selection of patients, and can be used as first line investigation.

Abstract
Background and study aims Small bowel capsule endoscopy [SBCE) has an established role in investigating suspected small bowel bleeding [SSBB). Identification of a biomarker to predict pathology would maximize utility of this valuable diagnostic modality. This study aimed to investigate if fecal immunochemical test [FIT) could predict likelihood of small bowel pathology on SBCE. Patients and methods Patients referred for SBCE to investigate anaemia or suspected small bowel bleeding were prospectively recruited. All patients had negative upper and lower endoscopy prior to referral. A FIT ≥ 45 ug Hb/g was considered positive. SBCE was positive if a potential source of SSBB was identified. The primary endpoint was correlation between FIT and positive SBCE. Secondary endpoints were correlation between anemia and SBCE and a combination of anemia plus FIT and SBCE. Results Fifty-one patients were included in the final study cohort. 29.4 % had a positive FIT, 33.3 % were anemic, and 25.5 % patients had significant SBCE findings. There was a statistically significant association between positive FIT and pathology on SBCE (OR 12, 95 % CI [2.8 - 51.9), P = 0.001). Sensitivity and specificity of positive FIT in predicting SBCE findings were 69 % and 84 %, respectively. A normal Hb had an NPV of 83 % (OR 0.30, P = 0.09). Combining Hb and FIT was statistically significant in predicting pathology on SBCE (OR 9.14, 67 % PPV, 82 % NPV, P = 0.025). Conclusion FIT ≥ 45 ug Hb/g is a useful tool in predicting small bowel pathology on SBCE. Use of this biomarker alone, or in combination with serum haemoglobin, has value as a screening tool and may help to better triage patients referred for SBCE.

Abstract
BACKGROUND Obscure gastrointestinal bleeding (OGIB) is a common but embarrassing problem for gastroenterologists. Most bleeding lesions associated with OGIB are present in the small intestine and sometimes cannot be identified due to the difficulty associated with physical accessibility. Capsule endoscopy (CE) and double-balloon enteroscopy (DBE) have enabled in the process of diagnosing and have evolved to become approaches to treating OGIB. SUMMARY CE is a minimally invasive procedure and has a high diagnostic yield in patients with OGIB. DBE offers additional advantage of biopsy collection for pathological diagnosis and therapeutic intervention, but it should be noted that it sometimes causes severe adverse events such as acute pancreatitis, intestinal bleeding, and intestinal perforation. CE should be performed early in the workup course of OGIB. Positive CE findings enhance the diagnostic yield of subsequent DBE, and the effective therapeutic intervention improves the clinical outcomes of OGIB patients. On the contrary, there are no clear guidelines for further investigation of patients with negative CE findings at the present. Although patients in stable general condition may only require follow-up, repeated CE is useful to detect positive findings in patients with evidence of sustained bleeding and progressing anemia. We have revealed that repeated CE has higher positive finding rate than DBE in OGIB patients with negative CE findings in a preliminary study. Key Messages: CE and DBE have complementary roles in the management of OGIB, and the precise timing and proper sequence may be important for the approach to treating OGIB.

Abstract
BACKGROUND In Lombardia, one of the 20 Italian administrative Regions, small-bowel capsule endoscopy (SBCE) was introduced in 2001. In January 2011, the Regional Health Authorities established a reimbursement for outpatient SBCE. AIM To prospectively record data on SBCE between 2011-2013 and compare them to similar data retrospectively collected from the same geographical area (covering the period 2001-2008) and published in 2008. METHODS Consecutive SBCEs performed between January 2011 and December 2013 in Lombardia were prospectively collected. RESULTS In 3 years, 3142 SBCEs were collected; the diagnostic yield (DY) and the overall complication rate were 48.4 and 0.9%, respectively. The main indication was suspected small-bowel bleeding (76.6% of patients); complete small-bowel inspection was achieved in 2796 (89.0%) patients. SBCE was performed as an outpatient procedure in 1945 patients (61.9%). A significant increase in the rate of patients undergoing SBCE for suspected small-bowel bleeding was observed from 2001-2008 to 2011-2013 (67.3 vs. 76.1%; p < 0.001). There was an increase in the number of complete small-bowel examinations (81.2 vs. 89.0%; p < 0.001) and of outpatient SBCEs (6.7 vs. 61.9%; p < 0.001). Conversely, both the retention rate (2.1 vs. 0.8%; p < 0.001) and the rate of patients undergoing SBCE for Crohn's disease (11.5 vs. 5.5%; p < 0.001) decreased significantly. The overall DY remained stable (50.6 vs. 48.4%; p = 0.089). CONCLUSION Our study shows that, over 13 years, the SBCE safety profile and completion rate significantly improved over time; a change in the spectrum of clinical indications was also observed.

Abstract
AIM To evaluate the impact of the timing of capsule endoscopy (CE) in overt-obscure gastrointestinal bleeding (OGIB).
METHODS Retrospective, single-center study, including patients submitted to CE in the setting of overt-OGIB between January 2005 and August 2017. Patients were divided into 3 groups according to the timing of CE (≤ 48 h; 48 h-14 d; ≥ 14 d). The diagnostic and therapeutic yield (DY and TY), the rebleeding rate and the time to rebleed were calculated and compared between groups. The outcomes of patients in whom CE was performed before (≤ 48 h) and after 48 h (> 48 h), and before (< 14 d) and after 14 d (≥ 14 d), were also compared.
RESULTS One hundred and fifteen patients underwent CE for overt-OGIB. The DY was 80%, TY-46.1% and rebleeding rate - 32.2%. At 1 year 17.8% of the patients had rebled. 33.9% of the patients performed CE in the first 48 h, 30.4% between 48h-14d and 35.7% after 14 d. The DY was similar between the 3 groups (P = 0.37). In the ≤ 48 h group, the TY was the highest (66.7% vs 40% vs 31.7%, P = 0.005) and the rebleeding rate was the lowest (15.4% vs 34.3% vs 46.3% P = 0.007). The time to rebleed was longer in the ≤ 48 h group when compared to the > 48 h groups (P = 0.03).
CONCLUSION Performing CE within 48 h from overt-OGIB is associated to a higher TY and a lower rebleeding rate and longer time to rebleed.

Abstract
Obscure gastrointestinal bleeding (OGIB) accounts for 5% of all gastrointestinal (GI) bleeding cases and is often caused by small bowel lesions. Capsule endoscopy (CE), which allows non-invasive visualization of the small bowel mucosa, has revolutionized the evaluation of OGIB. CE is preferred by both patients and physicians mainly because of its non-invasiveness, and is widely used as the first-line diagnostic modality for OGIB. The diagnostic yield of CE in OGIB has been reported to be in the range of 32% to 83%. Although no direct comparison has been made, a meta-analysis showed similar diagnostic yields between CE and double-balloon enteroscopy (DBE) for OGIB. However, CE could enhance the yield of subsequent DBE and serve as a guide for optimizing the insertion route for DBE. Even after negative CE, selected patients could benefit from second-look CE for OGIB. In terms of outcomes, a favorable clinical impact after CE has been reported in several studies. However, observations indicate that CE might not influence clinical outcomes directly, but rather play a role in selecting patients with OGIB who are likely to benefit from subsequent evaluation and intervention.

Abstract
Background/Aims To investigate the various etiologies, yields, and effects of capsule endoscopy (CE) on management and complications, along with follow up of patients with obscure gastrointestinal (GI) bleeding. Methods The study group of patients included those having obscure, overt, or occult GI bleeding. The findings were categorized as (A) obvious/definitive, (B) equivocal, or (C) negative. Any significant alteration in patient management post CE in the form of drug or surgical intervention was noted. Results Total patients included in the study were 68 (48 males and 20 females). The ratio of male:female was 2.4:1. The age ranged between 16 years to 77 years. Mean age for males was 62±14 years, for females 58±16 years. The total yield of CE with definitive lesions was in 44/68 (65.0%) of patients. In descending order (A) angiodysplasia 16/68 (23.53%), (B) Crohn's disease 10/68 (14.70%), (C) non-steroidal anti-inflammatory drug enteropathy 8/68 (11.76%), (D) small bowel ulcers 4/68 (5.88%), (E) jejunal and ileal polyps 2/68 (2.94%), (F) intestinal lymphangiectasis 2/68 (2.94%), and (G) ileal hemangiomas 2/68 (2.94%) were followed. Equivocal findings 12/68 (17.65%) and negative study 12/68 (17.65%) was found. Complications in the form of capsule retention in the distal ileum were noted in 2/68 (2.94%) subjects. Statistically, there was a higher probability of finding the etiology if the CE was done during an episode of bleeding. Conclusions CE plays an important role in diagnosing etiologies of obscure GI bleeding. Its role in influencing the management outcome is vital.

Abstract
Small bowel evaluation is a challenging task and has been revolutionized by high-quality contrasted sectional imaging (CT enterography - CTE) and magnetic resonance enterography (MRE) as well as by small bowel capsule endoscopy (SBCE). The decision of which technique to employ during the investigation of small bowel diseases is not always simple or straightforward. Moreover, contraindications may preclude the use of these techniques in some patients, and although they are noninvasive procedures, may present with various complications. SBCE plays a crucial role in the investigation of both obscure gastrointestinal bleeding and Crohn's disease, but it is also useful for surveillance of patients with Peutz-Jeghers syndrome, while CTE is very accurate in small bowel tumours and in established Crohn's Disease, and its use in patients presenting with gastrointestinal bleeding is increasing. MRE, an expensive and not widely available technique, is essential for the study of patients with Crohn's Disease, and presents an attractive alternative to SBCE in Peutz-Jeghers syndrome surveillance. These diagnostic modalities are often not competitive but synergistic techniques. Knowing their characteristics, strengths and limitations, indications, contraindications and potential complications, as well as the adaptation to local availability and expertise, is essential to better select which procedures to perform in each patient, both safely and effectively, in order to optimize management and improve patient outcomes.

Abstract
OBJECTIVE This study aimed to identify the risk factors associated with rebleeding and long-term outcomes after capsule endoscopy (CE) for obscure gastrointestinal bleeding (OGIB) in a follow-up study. METHODS Data of consecutive patients who underwent CE due to OGIB from June 2002 to January 2012 were retrospectively reviewed. The Cox proportional hazard model was used to evaluate the risk factors associated with rebleeding, while Kaplan-Meier survival curves and the log-rank test were used to analyze cumulative rebleeding rates. RESULTS The overall rebleeding rate after CE in patients with OGIB was 28.6% (97/339) during a median follow-up of 48 months (range 12-112 months). Multivariate analysis showed that age ≥60 years (hazard ratio [HR] 2.473, 95% confidence interval [CI] 1.576-3.881, P = 0.000), positive CE findings (HR 3.393, 95% CI 1.931-5.963, P = 0.000), hemoglobin ≤70 g/L before CE (HR 2.010, 95% CI 1.261-3.206, P = 0.003), nonspecific treatments (HR 2.500, 95% CI 1.625-3.848, P = 0.000) and the use of anticoagulants, antiplatelet or non-steroidal anti-inflammatory drugs after CE (HR 2.851, 95% CI 1.433-5.674, P = 0.003) were independent risk factors associated with rebleeding. Univariate analysis showed that chronic hepatitis was independently associated with rebleeding in CE-negative patients (P = 0.021). CONCLUSIONS CE has a significant impact on the long-term outcome of patients with OGIB. Further investigation and close follow-up in patients with OGIB and those with negative CE findings are necessary.

Abstract
Iron deficiency anemia (IDA) is common and often under recognized problem in the elderly. It may be the result of multiple factors including a bleeding lesion in the gastrointestinal tract. Twenty percent of elderly patients with IDA have a negative upper and lower endoscopy and two-thirds of these have a lesion in the small bowel (SB). Capsule endoscopy (CE) provides direct visualization of entire SB mucosa, which was not possible before. It is superior to push enteroscopy, enteroclysis and barium radiography for diagnosing clinically significant SB pathology resulting in IDA. Angioectasia is one of the commonest lesions seen on the CE in elderly with IDA. The diagnostic yield of CE for IDA progressively increases with advancing age, and is highest among patients over 85 years of age. Balloon assisted enteroscopy is used to treat the lesions seen on CE. CE has some limitations mainly lack of therapeutic capability, inability to provide precise location of the lesion and false positive results. Overall CE is a very safe and effective procedure for the evaluation of IDA in elderly.

Abstract
Although the introduction of double-balloon enteroscopy has greatly improved the diagnostic rate, definite diagnosis of Meckel’s diverticulum far from the ileocecal valve is still impossible in most cases. We explored the role of magnetic resonance (MR) enterography in detecting bleeding from Meckel’s diverticulum that can not be confirmed via double-balloon enteroscopy. This study describes a case of male patient with bleeding from Meckel’s diverticulum diagnosed with MR enterography of the small intestine. No bleeding lesion was found via colonoscopy, anal enteroscopy, or oral colonoscopy. MR enterography of the small intestine revealed an occupying lesion of 3.0 cm in the lower segment of the ileum. The patient was transferred to the Department of Abdominal Surgery of our hospital for surgical treatment. During surgery, a mass of 3 cm × 2 cm was found 150 cm from the ileocecal valve, in conjunction with congestion and edema of the corresponding mesangium. Intraoperative diagnosis was small bowel diverticulum with bleeding. The patient underwent partial resection of the small intestine. Postoperative pathology showed Meckel’s diverticulum containing pancreatic tissues. He was cured and discharged 7 d after operation. We conclude that MR enterography of the small intestine has greatly improved the diagnosis rate of Meckel’s diverticulum, particularly in those patients with the disease which can not be confirmed via double-balloon enteroscopy.

Abstract
BACKGROUND Iron-deficiency anemia (IDA) is the most common cause of anemia worldwide. Current guidelines recommend the use of small-bowel capsule endoscopy (SBCE) in IDA. Evidence of the validity of SBCE in patients with IDA alone is still limited. OBJECTIVE To assess the diagnostic yield (DY) of SBCE in IDA by pooling data from relevant studies. DESIGN Systematic review and meta-analysis. Fixed-effects or random-effects models were used as appropriate. SETTING Studies that estimated the DY of SCBE in IDA were identified. Two investigators independently conducted the search and data extraction. PATIENTS A total of 24 studies enrolling 1960 patients with IDA who underwent SBCE were included. MAIN OUTCOME MEASUREMENTS Per-patient DY, with 95% confidence intervals. Subgroup analysis was also performed. RESULTS The pooled DY of SBCE in IDA, evaluated by a random-effects model, was 47% (95% CI, 42%-52%), but there was statistically significant heterogeneity among the included studies (inconsistency index [I(2)] = 78.8%, P < .0001). The pooled DY of SBCE in studies focused solely on patients with IDA (subset 1, 4 studies) was 66.6% (95% CI, 61.0%-72.3%; I(2) = 44.3%); conversely, that of studies not focusing only on IDA patients (subset 2, 20 studies) was 44% (95% CI, 39%-48%; I(2) = 64.9%). In particular, more vascular (31% vs 22.6%, P = .007), inflammatory (17.8% vs 11.3%, P = .009), and mass/tumor (7.95% vs 2.25%, P < .0001) lesions were detected with SBCE in patients participating in the studies in subset 1. LIMITATIONS Heterogeneity of studies, retrospective design, and selection bias. CONCLUSIONS This analysis demonstrates the validity of SBCE in the investigation of patients with IDA and negative findings on a previous diagnostic workup, although certain factors such as heterogeneity and quality of the included studies should be taken into account.
