Introduction: Deciding which patients with suspected small bowel bleeding (SSB) would benefit most from small bowel capsule endoscopy (SBCE) is challenging. Our aim was to perform an external validation of the recently developed SSB Capsule Diagnostic (Dx) score that includes 3 variables (hospital admission with overt bleeding, hemoglobin <6.4 g/dL and age <54 years) and has been shown to be potentially useful in limiting the use of SBCE in SSB low-risk patients., Methods: Retrospectively included all adult patients submitted to SBCE for SSB between November 2007 and December 2019. Patients' demographic, clinical and laboratorial data at the time of SBCE were recorded. Small bowel lesions were classified according to Saurin classification. The SSB Capsule Dx score was calculated, and its calibration and discrimination ability were assessed., Results: We assessed 473 SBCEs for SSB. Patients' mean age was 61.2 ± 17.9 years and 65.8% were female. P2 lesions were present in 36.2% of SBCEs. There was a significant association between the score and P2 lesions (p < 0.001). Mean score was -0.21 ± 0.87 having a fair accuracy toward the outcome (C-statistic 0.700; 95% confidence interval, 0.652-0.749; p < 0.001). A cutoff value of 0 was found to have a high sensitivity (86.0%) and negative predictive value (84.9%) for the diagnosis of P2 lesions at SBCE., Conclusion: Patients with a SSB Capsule Dx score <0 are unlikely to have a significant lesion on SBCE, thus its routine use in the clinical practice may be useful in the identification of low-risk SSB patients., (© 2024 S.

Background: Pan-intestinal capsule endoscopy (PCE) evaluates the small bowel and colon noninvasively. This study evaluated diagnostic accuracy and safety of PCE vs. colonoscopy as first-line examination in suspected mid-lower gastrointestinal bleeding (MLGIB)., Methods: In this prospective, single-center, single-blinded cohort study, consecutive patients with suspected MLGIB underwent PCE followed by same-day colonoscopy. Diagnostic accuracy for potentially hemorrhagic lesions (PHLs; combined diagnosis by PCE + colonoscopy) and incidence of adverse events were assessed., Results: 100 patients were included (median age 70 [range 18-92] years; 65% female). PHLs were diagnosed in 46 patients, including small-bowel and/or colon angioectasias in 32. PCE correctly identified 54 individuals without PHLs, and 95.7% (44/46) of those with PHLs vs. 50.0% (23/46) for colonoscopy (P<0.01). PHLs were detected by PCE alone in 65.2% (30/46), both examinations in 28.3% (13/46), and colonoscopy alone in 6.5% (3/46). PHLs were diagnosed at the ileocolonic region in 28% of patients, with PCE diagnosing 25/28 cases (89.3%) and colonoscopy diagnosing 23/28 (82.1%; P=0.13). Interventional procedures were performed at colonoscopy in 13/81 patients with iron-deficiency anemia (16.0%) vs. 6/19 patients with overt bleeding (31.6%; P<0.01). No significant adverse events occurred with PCE vs. 2% with colonoscopy., Conclusions: In patients with MLGIB, PCE avoided further invasive procedures in >50% of patients. PCE was safe and more effective than colonoscopy in identifying PHL both in the small bowel and colon. These results support the potential use of PCE as first-line examination in patients with suspected MLGIB., Competing Interests: B.

Background: Acid suppressing drugs (ASD) are generally used in acute pancreatitis (AP); however, large cohorts are not available to understand their efficiency and safety. Therefore, our aims were to evaluate the association between the administration of ASDs, the outcome of AP, the frequency of gastrointestinal (GI) bleeding and GI infection in patients with AP., Methods: We initiated an international survey and performed retrospective data analysis on AP patients hospitalized between January 2013 and December 2018., Results: Data of 17,422 adult patients with AP were collected from 59 centers of 23 countries. We found that 23.3% of patients received ASDs before and 86.6% during the course of AP. ASDs were prescribed to 57.6% of patients at discharge. ASD administration was associated with more severe AP and higher mortality. GI bleeding was reported in 4.7% of patients, and it was associated with pancreatitis severity, mortality and ASD therapy. Stool culture test was performed in 6.3% of the patients with 28.4% positive results. Clostridium difficile was the cause of GI infection in 60.5% of cases. Among the patients with GI infections, 28.9% received ASDs, whereas 24.1% were without any acid suppression treatment. GI infection was associated with more severe pancreatitis and higher mortality., Conclusions: Although ASD therapy is widely used, it is unlikely to have beneficial effects either on the outcome of AP or on the prevention of GI bleeding during AP. Therefore, ASD therapy should be substantially decreased in the therapeutic management of AP., Competing Interests: Declaration of competing interest The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2020 IAP and EPC.

Introduction: Small bowel capsule endoscopy (SBCE) is the gold standard for mid-gastrointestinal bleeding (MGIB). No score has been developed to predict the risk of small bowel rebleeding after SBCE., Objective: Creating a predictive small bowel rebleeding risk score for MGIB, after initial SBCE., Methods: Retrospective, single center study, including SBCEs for MGIB, from June 2006 to October 2016. The minimum follow-up was 12 months. Univariate analysis and a multivariable Cox regression model tested the association with rebleeding. Statistically significant variables were used to compute the score. The score's accuracy was tested through a receiver operating characteristic (ROC) curve. A classification tree identified risk groups. For internal validation, we performed a 5-fold cross validation., Results: We assessed 357 SBCEs for MGIB, of which 88 (24.6%) presented rebleeding during follow-up. Seven variables were used to compute a risk-predicting score - the RHEMITT score - namely, renal disease; heart failure; endoscopic capsule P1/P2 lesions; major bleeding; incomplete capsule; tobacco consumption; and endoscopic treatment. The score presented good accuracy toward the outcome (area under the curve ROC 0.842, 95% CI 0.757-0.927). We established 3 rebleeding risk groups: low (0-3 points); intermediate (4-10 points); and high (+11 points)., Conclusion: A new MGIB score, named RHEMITT, accurately anticipates the individual risk of small bowel rebleeding after initial SBCE., (© 2019 S.

Background and Study Aims: Available scoring systems to assess the risk for major bleeding in patients on chronic anticoagulation seem inadequate in predicting higher diagnostic yields of small bowel capsule endoscopy (SBCE) or higher rebleeding rates in patients with suspected small bowel bleeding. The aim of this study was to evaluate the ability of the new ORBIT score in predicting positive findings of SBCE or higher rebleeding rates in chronically anticoagulated patients with suspected small bowel bleeding., Patients and Methods: Retrospective analysis of 570 patients who consecutively underwent SBCE for the study of suspected small bowel bleeding. For each of the 67 patients who were on chronic anticoagulation, ORBIT score (Older age, Reduced hemoglobin/hematocrit, Bleeding history, Insufficient kidney function and Treatment with antiplatelets) was calculated. Patients were classified as high-risk (ORBIT score ≥4) or low/intermediate-risk (ORBIT score <4). Data on SBCE findings, diagnostic yield and rebleeding were compared between groups., Results: When ORBIT score was calculated, 41 and 26 patients were classified as low/intermediate-risk and high-risk, respectively. When low/intermediate-risk and high-risk groups were compared, no differences were found in the diagnostic yield of SBCE (39.0% vs. 23.1%; p = .176). However, in high-risk patients, rebleeding was significantly more common than in low/intermediate-risk patients (80.0% vs. 36.6%; p = .003)., Conclusions: In patients presenting with suspected small bowel bleeding and on chronic anticoagulation, the new ORBIT score seems promising in identifying those with a higher risk of rebleeding, in whom a closer follow-up and a more aggressive diagnostic and therapeutic strategy is advisable.

Upper gastrointestinal bleeding (UGIB) is a potentially life-threatening condition and is the most common medical emergency managed by gastroenterologists. Despite being one of the most antique medical problems, recent studies have been slowly changing the management of these patients, which should nowadays include not only initial resuscitation, but also risk stratification, pre-endoscopic therapy, endoscopy treatment, and post-procedure care. The aim of this paper is to review the extended approach to the patient with non-portal hypertension related UGIB.

Background: Small bowel capsule endoscopy represents the initial investigation for obscure gastrointestinal bleeding. Flexible spectral imaging colour enhancement (FICE) is a virtual chromoendoscopy technique designed to enhance mucosal lesions, available in different settings according to light wavelength-- FICE1, 2 and 3., Aims: To compare the diagnostic yield of FICE1 and white light during capsule endoscopy in patients with obscure gastrointestinal bleeding., Methods: Retrospective single-centre study including 60 consecutive patients referred for small bowel capsule endoscopy for obscure gastrointestinal bleeding. Endoscopies were independently reviewed in FICE1 and white light; findings were then reviewed by another researcher, establishing a gold standard. Diagnostic yield was defined as the presence of lesions with high bleeding potential (P2) angioectasias, ulcers or tumours., Results: Diagnostic yield using FICE1 was significantly higher than white light (55% vs. 42%, p=0.021). A superior number of P2 lesions was detected with FICE1 (74 vs. 44, p=0.003), particularly angioectasias (54 vs. 26, p=0.002), but not ulcers or tumours., Conclusions: FICE1 was significantly superior to white light, resulting in a 13% improvement in diagnostic yield, and potentially bleeding lesions particularly angioectasias were more often observed. Our results support the use of FICE1 while reviewing small bowel capsule endoscopy for obscure gastrointestinal bleeding., (Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

Background and Aim: A significant proportion of patients presenting with obscure gastrointestinal bleeding (OGIB) have negative small bowel capsule endoscopy (SBCE) examinations, and yet remain at risk of rebleeding. We aimed to evaluate whether a second-look review of SBCE images using flexible spectral color enhancement (FICE) may improve the detection of potentially bleeding lesions., Materials and Methods: This was a retrospective, single-center study including consecutive patients with OGIB subjected to SBCE, whose standard white light examination was nondiagnostic. Each SBCE was reviewed using FICE 1. New findings were labeled as either P1 or P2 lesions according to bleeding potential. Patients were followed up to assess the incidence of rebleeding., Results: A total of 42 consecutive patients were included. Sixteen patients (38%) experienced rebleeding after a mean follow-up of 26 months. Review of SBCE images using FICE 1 enabled the identification of previously unrecognized P2 lesions, mainly angioectasias, in nine patients (21%) and P1 lesions, mainly erosions, in 26 patients (62%). Among patients who experienced rebleeding, 13/16 (81%) were diagnosed with P1 lesions with FICE 1 (P=0.043), whereas 3/16 (19%) had confirmed nondiagnostic SBCE and only 1/16 (6%) had newly diagnosed P2 (plus P1) lesions. An alternative source of bleeding outside the small bowel was found in only 3/16 (19%) patients with rebleeding during the follow-up., Conclusion: In a significant proportion of patients with OGIB, FICE 1 may detect potentially bleeding lesions previously missed under conventional white light SBCE. Review of nondiagnostic SBCE with FICE 1 may be a valuable strategy to obviate the need for further investigations in patients with OGIB, particularly for those who experience rebleeding.

Background/aim: Small bowel capsule endoscopy (SBCE) is currently a fundamental tool in the etiological study of obscure gastrointestinal bleeding (OGIB). However, the impact of a negative exam and the risk of rebleeding are not entirely known. The aim of this study was to evaluate the outcomes of patients with OGIB and a negative SBCE examination in terms of follow-up duration, additional diagnostic studies, and achievement of a diagnosis as well as to assess the incidence of rebleeding and possible associated factors., Materials and Methods: We retrospectively analyzed 256 patients who consecutively underwent an SBCE examination for the study of OGIB between April 2006 and December 2011, and then selected the 79 whose results excluded potentially bleeding lesions. Eleven patients were lost to follow-up and the remaining 68 were eligible for a nested case-control analysis. Pre-SBCE and post-SBCE information was collected, including follow-up interval and incidence of rebleeding, defined as admission to the hospital for symptomatic anemia, need for blood transfusion, decrease in hemoglobin value of greater than 2 g/dl, or evidence of melena or hematochezia. Univariate analysis included age, sex, OGIB presentation (occult or visible), hemoglobin levels at presentation, and comorbidities., Results: In the 68 patients analyzed, the mean age was 52±18 years and 61.8% were women. The OGIB was occult in 54 patients (79.4%) and overt in 14 patients (20.6%). Patients were followed up for an average of 32 months. Thirty-nine patients (57.4%) underwent further diagnostic investigations during the period of follow-up and a cause for the gastrointestinal bleeding was found in five of them. Rebleeding was documented in 16 (23.5%) patients, occurring on average 15±13.8 months after the SBCE. Male sex was associated significantly with higher incidence of rebleeding (P=0.004)., Conclusion: Approximately one quarter of patients with OGIB and negative SBCE examination will experience rebleeding, with higher incidence among men; thus, a negative SBCE in this setting is not reassuring. As the vast majority of rebleeding episodes seem to occur within the following 2 years after SBCE, the maintenance of regular medical surveillance during the above-mentioned period of time after a negative SBCE seems advisable.

Background: In patients with acute nonvariceal upper gastrointestinal bleeding (NVUGIB), early (≤ 24 h) endoscopy is recommended following hemodynamic resuscitation. Nevertheless, scarce data exist on the optimal timing of endoscopy in patients with NVUGIB receiving anticoagulants. Objective: To analyze how the timing of endoscopy may influence outcomes in anticoagulants users admitted with NVUGIB. Methods: Retrospective cohort study which consecutively included all adult patients using anticoagulants presenting with NVUGIB between January 2011 and June 2020. Time from presentation to endoscopy was assessed and defined as early (≤ 24 h) and delayed (> 24 h). The outcomes considered were endoscopic or surgical treatment, length of hospital stay, intermediate/intensive care unit admission, recurrent bleeding, and 30-day mortality. Results: From 636 patients presenting with NVUGIB, 138 (21.7%) were taking anticoagulants. Vitamin K antagonists were the most frequent anticoagulants used (63.8%, n = 88). After adjusting for confounders, patients who underwent early endoscopy (59.4%, n = 82) received endoscopic therapy more frequently (OR 2.4; 95% CI 1.1–5.4; P = 0.034), had shorter length of hospital stay [7 (IQR 6) vs 9 (IQR 7) days, P = 0.042] and higher rate of intermediate/intensive care unit admission (OR 2.7; 95% CI 1.3 – 5.9; P = 0.010) than patients having delayed endoscopy. Surgical treatment, recurrent bleeding, and 30-day mortality did not differ significantly between groups. Conclusion: Early endoscopy (≤ 24 h) in anticoagulant users admitted with acute nonvariceal upper gastrointestinal bleeding is associated with higher rate of endoscopic treatment, shorter hospital stay, and higher intermediate/intensive care unit admission. The timing of endoscopy did not influence the need for surgical intervention, recurrent bleeding, and 30-day mortality. [ABSTRACT FROM AUTHOR]

Introduction: Foreign body (FB) ingestion is a common indication for urgent esophagogastroduodenoscopy (EGD). Nevertheless, most pass spontaneously through the gastrointestinal (GI) tract. Differently from GI bleeding, there is no validated score aiming to identify "low‐risk" patients in suspected FB ingestion. We aimed to create a score able to discriminate patients who are candidates to emergent EGD in this scenario. Methods: Retrospective study of consecutive patients admitted for suspected FB in the upper GI tract between 2016 and 2021. The evaluated outcome was endoscopic confirmation of FB in the esophagus. Variables significantly associated with the outcome on multivariate analysis were computed into a score predicting endoscopic confirmation. Results: We included 228 patients. From these, 97 (42.5%) had a confirmed FB in EGD. Time since ingestion <6 h (OR = 4.0; P = 0.042), absence of any meal after FB ingestion (OR = 7.1; P = 0.005), dysphagia (OR = 11.8; P < 0.001), odynophagia (OR = 4.6; P = 0.004), and drooling (OR = 15.1; P < 0.001) were independent predictors of confirmed FB. These variables were used to compute a FB predicting score—the Decision‐To‐Scope (DTS) Score: time since ingestion <6 h (+1 point), absence of meals (+2 points), dysphagia (+3 points), odynophagia (+1 point), and drooling (+4 points). DTS‐Score had excellent accuracy to predict the outcome (AUC = 0.953; 95%CI = 0.928–0.977; P < 0.001). The optimal cutoff to identify low‐risk patients was a score ≤5 (sensitivity 85.0% and specificity 94.7%). Conclusions: More than half of the suspected FB were not confirmed by EGD. The DTS‐Score presented excellent accuracy at stratifying patients' risk and may contribute to the decision to perform emergent EGD in suspected FB ingestion. [ABSTRACT FROM AUTHOR]

It was shown that Capsule Endoscopy Small Bowel Angiodysplasia Activity Index (CESBAI) is a simple and reproducible method, with low interobserver variability regarding SBAD evaluation by small bowel capsule endoscopy. To the best of our knowledge, this is the first article providing an objective method that could fill the gap in the evaluation of the severity of small bowel angiodysplasia (SBAD) based on small bowel capsule endoscopy findings.
