Zhang SH, Fan MW, Chen Y, Hu YB, Liu CX. Computed tomography three-dimensional reconstruction in the diagnosis of bleeding small intestinal polyps: A case report. World J Clin Cases 2024; 12:2831-2836. [PMID: 38899307 PMCID: PMC11185330 DOI: 10.12998/wjcc.v12.i16.2831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 02/15/2024] [Accepted: 04/09/2024] [Indexed: 05/29/2024] Open
Abstract
BACKGROUND Computed tomography (CT) small bowel three-dimensional (3D) reconstruction is a powerful tool for the diagnosis of small bowel disease and can clearly show the intestinal lumen and wall as well as the outside structure of the wall. The horizontal axis position can show the best adjacent intestinal tube and the lesion between the intestinal tubes, while the coronal position can show the overall view of the small bowel. The ileal end of the localization of the display of excellent, and easy to quantitative measurement of the affected intestinal segments, the sagittal position for the rectum and the pre-sacral lesions show the best, for the discovery of fistulae is also helpful. Sagittal view can show rectal and presacral lesions and is useful for fistula detection. It is suitable for the assessment of inflammatory bowel disease, such as assessment of disease severity and diagnosis and differential diagnosis of the small bowel and mesenteric space-occupying lesions as well as the judgment of small bowel obstruction points. CASE SUMMARY Bleeding caused by small intestinal polyps is often difficult to diagnose in clinical practice. This study reports a 29-year-old male patient who was admitted to the hospital with black stool and abdominal pain for 3 months. Using the combination of CT-3D reconstruction and capsule endoscopy, the condition was diagnosed correctly, and the polyps were removed using single-balloon enteroscopy-endoscopic retrograde cholangiopancreatography without postoperative complications. CONCLUSION The role of CT-3D in gastrointestinal diseases was confirmed. CT-3D can assist in the diagnosis and treatment of gastrointestinal diseases in combination with capsule endoscopy and small intestinal microscopy.

Video capsule endoscopy in overt and occult obscure gastrointestinal bleeding: Insights from a single-center, observational study in Japan. DEN OPEN 2024; 4:e354. [PMID: 38567032 PMCID: PMC10985219 DOI: 10.1002/deo2.354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 02/15/2024] [Accepted: 03/08/2024] [Indexed: 04/04/2024]
Abstract
Objective This study aimed to evaluate the use of video capsule endoscopy (VCE) in patients with obscure gastrointestinal bleeding (OGIB), compare cases of overt and occult OGIB, assess the rates of balloon-assisted enteroscopy (BAE) interventions and rebleeding, and identify predictive markers of positive VCE findings. Methods Medical records of 430 patients who underwent VCE for OGIB between 2004 and 2022 were analyzed. Occult OGIB was defined as IDA or positive fecal occult blood, whereas overt OGIB was defined as clinically imperceptible bleeding. We retrospectively analyzed demographics, VCE findings based on Saurin classification (P0, P1, and P2), outcome of BAE interventions, and rebleeding rates. Results A total of 253 patients with overt OGIB and 177 with occult OGIB were included. P1 findings were predominant in both groups, with a similar distribution. The percentage of patients receiving conservative therapy was higher in P1 than in P2 for both overt and occult OGIB. BAE was more frequently performed in P2 than in P1 VCE (83.0% vs. 35.3% in overt OGIB, 84.4% vs. 24.4% in occult OGIB). The percentage of positive findings and intervention in total BAE performed patients were comparable in P1 and P2 of overt OGIB, whereas these percentages in P2 were more than P1 of occult OGIB. Conclusion VCE effectively identified OGIB lesions requiring intervention, particularly occult OGIB lesions, potentially reducing unnecessary BAE. Rebleeding rates varied according to the VCE findings, emphasizing the importance of follow-up in high-risk patients.

Abstract
Background and study aims Capsule endoscopy (CE) is commonly used as the initial exam for suspected mid-gastrointestinal bleeding after normal upper and lower endoscopy. Although the assessment of the small bowel is the primary focus of CE, detecting upstream or downstream vascular lesions may also be clinically significant. This study aimed to develop and test a convolutional neural network (CNN)-based model for panendoscopic automatic detection of vascular lesions during CE. Patients and methods A multicentric AI model development study was based on 1022 CE exams. Our group used 34655 frames from seven types of CE devices, of which 11091 were considered to have vascular lesions (angiectasia or varices) after triple validation. We divided data into a training and a validation set, and the latter was used to evaluate the model's performance. At the time of division, all frames from a given patient were assigned to the same dataset. Our primary outcome measures were sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), and an area under the precision-recall curve (AUC-PR). Results Sensitivity and specificity were 86.4% and 98.3%, respectively. PPV was 95.2%, while the NPV was 95.0%. Overall accuracy was 95.0%. The AUC-PR value was 0.96. The CNN processed 115 frames per second. Conclusions This is the first proof-of-concept artificial intelligence deep learning model developed for pan-endoscopic automatic detection of vascular lesions during CE. The diagnostic performance of this CNN in multi-brand devices addresses an essential issue of technological interoperability, allowing it to be replicated in multiple technological settings.

Abstract
BACKGROUND AND AIM Although small-bowel capsule endoscopy (CE) is widely used for obscure gastrointestinal bleeding (OGIB), long-term outcomes for OGIB patients after negative CE remain unclear. Herein, we defined negative CE as P0 (no bleeding potential) or P1 (less likely to bleed), based on the P classification using CE. We aimed to clarify long-term outcomes of patients with OGIB after negative CE. METHODS This single-center observational study enrolled 461 consecutive patients with OGIB who underwent CE from March 2014 to October 2021 and were followed up for >1 year. We examined rebleeding rates and predictive factors. RESULTS Two hundred and twenty-four (49%) patients had P0, and 237 (51%) had P1 findings. Rebleeding occurred in 9% and 16% of patients in the P0 and P1 groups, respectively. Two patients in the P0 group and 15 in the P1 group showed rebleeding from the small bowel. The rate of small-bowel rebleeding was significantly lower in the P0 group than that in the P1 group (1% vs 6%, P = 0.002), as was the cumulative rebleeding rate (P = 0.004). In the multivariate analysis, history of endoscopic hemostasis (hazard ratio [HR] = 15.958, 95% confidence interval [CI]:4.950-51.447, P < 0.001) and P1 CE findings (HR = 9.989, 95% CI: 2.077-48.030, P = 0.004) were independently predicted small-bowel rebleeding. CONCLUSIONS OGIB with P0 CE findings rarely showed rebleeding from the small bowel. Rebleeding may occur in patients with OGIB. Patients with history of endoscopic hemostasis for small-bowel lesions or P1 CE findings should be followed up intensively.

Abstract
Gastrointestinal bleeding of undetermined origin (GBUO) is defined as gastrointestinal bleeding without an identified cause or location despite an endoscopic assessment including an esogastroduodenal endoscopy (EOGD) and a total colonoscopy. A distinction is made between exteriorized GBUO and non-exteriorized occult GBUO. The causes in the majority of cases (vascular, inflammatory and tumoral) are located in the small intestine. The diagnostic strategy aiming to locate the origin of the GBUO is a real challenge. Innovation in endoscopic and imaging techniques has enabled minimally invasive exploration of the small intestine. In Europe, there is a strong consensus to recommend a video-capsule endoscopy (VCE) as the first-intention study. If there is reason to suspect intestinal obstruction, VCE is contraindicated and a CT-enteroscopy is then performed as first intention. Enteroscopy is performed as a second-line treatment, either for therapeutic purposes after a positive VCE or CT-enteroclysis, or for diagnostic purposes after a negative VCE. Finally, intraoperative enteroscopy (IOE) coupled with surgical exploration should be reserved either for therapeutic purposes in the event of impossibility or failure of preoperative enteroscopy, or for diagnostic purposes in the event of recurrent GBUO after failure of all other studies and explorations of the small intestine.

Abstract
Small intestinal lipomas are rare, but may cause obscure gastrointestinal bleeding. The endoscopic unroofing technique excises only the upper third of the lipoma and allows both histological confirmation and complete treatment with minimal risk of perforation. We present a rare case of obscure gastrointestinal bleeding caused by a jejunal lipoma. A 75-year-old man on antiplatelet therapy presented to our department with melena and anemia. Computed tomography revealed he had a 45-mm jejunal submucosal tumor with fat attenuation. Endoscopic resection using an endoscopic unroofing technique with double balloon enteroscopy was successfully performed. The tumor was confirmed to be a lipoma.

Abstract
Arteriovenous malformation (AVM) of the small bowel is a rare disease and can be sometimes difficult to treat due to the diagnostic difficulty. We herein report a case of small intestinal bleeding of AVM successfully treated with double-balloon enteroscopy (DBE) and laparoscope-assisted resection. A 44-year-old man complained of hematochezia and visited the previous doctor. He underwent gastroscopy and colonoscopy, but no bleeding site was detected. However, he rebled 2 days later and became hypotensive. Abdominal computed tomography revealed a hypervascular nodule in the jejunum. He was transferred to our institution for further treatment. DBE was performed and revealed a small pulsatile lesion with a tiny mucosal break. We then injected a marking tattoo. Two days later, he underwent an operation. We were able to easily locate the tattooed lesion laparoscopically and performed jejunal partial resection. His postoperative course was uneventful. DBE enabled a precise diagnosis and minimal invasive surgery.

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
Background and Aim Capsule endoscopy (CE) has been used in clinical examination among people of various ages, while few studies exclusively focused on the young. We aimed to explore its clinical features in young adults and those with obscure gastrointestinal bleeding (OGIB). Methods A total of 479 young adults aged 18–44 years were analyzed, with median age of 33 years. Primary positive findings of patients were classified into four kinds of lesions, and potential risk of bleeding among patients with OGIB was assessed based on Saurin classification (P0‐2 lesions). Results The overall completion rate and diagnostic yield of CE among young adults were 89.77 and 77.04%, respectively. Significant differences were found among overall completion rate/diagnostic yield and inpatient status/CE brand. Positive diagnostic yield among 157 patients with OGIB was 51.59% (P1‐2 lesions), and the significant risk of bleeding was 37.04% (P2 lesions). Among patients with OGIB in which 134 patients with a total of 216 lesions, ulceration was the commonest P2 lesions, followed by angioectasia and telangiectasia. Inpatient rate, completion rate, and diagnostic yield were higher among patients with overt OGIB, and disease categories of overt OGIB were different compared with occult OGIB. Conclusion CE is an optimal tool for discovering lesions in young adults and could play a role in evaluating the bleeding risk of young adults with OGIB.

World J Gastrointest Endosc 2022; 14:434-442. [PMID: 36051995 PMCID: PMC9329851 DOI: 10.4253/wjge.v14.i7.434] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 03/16/2022] [Accepted: 06/03/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Obscure gastrointestinal (GI) bleeding is defined as persistent bleeding despite negative evaluation with both esophagogastroduodenoscopy and colonoscopy and can be secondary to small intestinal pathology. Standard endoscopy as well as push endoscopy can be a challenge in those with altered anatomy given inaccessible areas as well as perforation risk. Single and double balloon enteroscopy can be warranted in this patient population in instances of obscure GI bleed.
AIM To assess the safety and diagnostic efficacy of balloon enteroscopy for obscure GI bleeding in patients with surgically altered anatomy.
METHODS A search was conducted through PubMed, MEDLINE, Google Scholar, Scopus, and Embase with the key words “enteroscopy,” “obscure bleeding,” and “altered anatomy,” to identify relevant articles in English with no restricted time frame. A search within the Reference Citation Analysis database was conducted to ensure inclusion of the latest high impact articles. Study types included in the review were prospective and retrospective reviews, case series, and case reports. The reference lists of these papers were also reviewed to find further papers that were applicable. The authors extracted the data from the studies that fit inclusion criteria. Data of interest included type of study, type of procedure, and type of altered anatomy, as well as the number of patients with any diagnostic or therapeutic intervention. Data was also recorded on procedure tolerance and complications. The data was analyzed with descriptive statistics.
RESULTS Our literature search yielded 14 studies that were included. There were 68 procedures performed with 61 unique patients subjected to these procedures. Forty-four (65%) of the procedures were double balloon, 21 (31%) were single balloon, and 3 (4%) were classified as through the scope balloon assisted. The most common altered anatomy types included Gastric Bypass Roux-en-Y, Pylorus Sparing Whipple, Orthotopic Liver Transplantation with Roux-en-Y, and Gastrojejunostomy Roux-en-Y. The procedures were successfully performed in each patient. There were 5 (7%) procedures that were complicated by perforation. Amongst the available data, the diagnostic yield was 48/59 (81%) and a therapeutic yield of 39/59 (66%). One patient was recommended surgical revision of their altered anatomy following enteroscopy.
CONCLUSION Balloon enteroscopy is a useful diagnostic modality in investigating obscure GI bleeding within those with surgically altered anatomy; however, precautions must be taken as this population may have increased perforation risk.

Rebleeding Rate and Risk Factors for Rebleeding after Device-Assisted Enteroscopy in Patients with Obscure Gastrointestinal Bleeding: A KASID Multicenter Study. Diagnostics (Basel) 2022; 12:diagnostics12040954. [PMID: 35454002 PMCID: PMC9027880 DOI: 10.3390/diagnostics12040954] [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: 03/02/2022] [Revised: 04/01/2022] [Accepted: 04/10/2022] [Indexed: 11/16/2022] Open
Abstract
Introduction: The impact of device-assisted enteroscopy (DAE) on long-term rebleeding in patients with obscure gastrointestinal bleeding (OGIB) exhibiting detectable small-bowel lesions remains unclear. We investigated the long-term rebleeding rate and predictive factors for DAE in patients with OGIB. Method: Patients with OGIB with small bowel lesions detected through DAE were enrolled at three Korean tertiary hospitals. Predictive risk factors associated with rebleeding were analyzed using the Cox regression analysis. Results: From April 2008 to April 2021, 141 patients were enrolled, including 38 patients (27.0%) with rebleeding. The rebleeding rates at 1, 2, and 3 years were 25.0%, 29.6%, and 31.1%, respectively. The Cox regression analysis revealed that multiple small-bowel lesions (hazard ratio [HR]: 2.551, 95% confidence interval [CI]: 1.157–5.627, p = 0.020), the need for more than five packed red blood cells (RBC) transfusions (HR: 2.704, 95% CI: 1.412–5.181, p = 0.003), and ulcerative lesions (HR: 1.992, 95% CI: 1.037–3.826, p = 0.039) were positively associated with rebleeding. Therapeutic interventions for patients with detectable lesions, overt bleeding (vs. occult bleeding), comorbidities, and medications were not associated with rebleeding. Conclusion: More than 25% of patients with OGIB having detectable small-bowel lesions had rebleeding. Patients with multiple lesions, a requirement of more than five packed RBC transfusions, and ulcerative lesions were associated with a higher risk of rebleeding.

Abstract
OBJECTIVE To analyze the diagnostic value of capsule endoscopy (CE) and double-balloon enteroscopy (DBE) in small bowel diseases. METHODS The clinical data of 134 cases of CE and 109 cases of DBE examined in our gastroscopy room from January 2016 to December 2019 were retrospectively analyzed. The two groups of patients were compared as to disease diagnostic rate, examination time, examination tolerance, and incidence of adverse reactions. RESULTS The two groups showed no significant difference in general data (all P>0.05). The DBE group showed a higher disease diagnostic rate than the CE group (P<0.05). Significantly higher rates of suspected intestinal bleeding were observed in the DBE group than those of the CE group (P<0.05), but no significant differences were found in the diagnosis of unexplained abdominal pain, abdominal distension, and others (all P>0.05). The DBE group required a longer examination time, and had a higher incidence of adverse reactions, and a lower examination tolerance than the CE group (P<0.05). CONCLUSION Both DBE and CE are effective in small bowel diseases diagnoses, but DBE demonstrated greater potential in diagnosing small bowel bleeding.

Abstract
BACKGROUND Suspected small bowel bleeding (SSBB) is the main indication for videocapsule endoscopy (VCE) and double balloon enteroscopy (DBE). We assessed the impact of both modalities in a large cohort of SSBB patients in a European tertiary center. METHODS We retrospectively evaluated consecutive patients with SSBB undergoing VCE and/or DBE from March 2001 to July 2020. Demographic/clinical parameters, anticoagulant therapies, technical characteristics and adverse events were collected, as well as diagnostic yield (DY), VCE-DBE concordance, hemoglobin (Hb) values before and after DBE, and complications. RESULTS 807 VCEs and 407 DBEs were performed in 751 patients. The DY was significantly higher in DBE compared with VCE (68.8% vs 57.7%), with the highest (75%) yield for overt active SB bleeding. The agreement between VCE and DBE was generally suboptimal (k = 0.059). This improved in cases where both procedures were done within 1-5 days of the other (k = 0.323). Post-procedural Hb values were significantly higher. In patients treated with direct oral anticoagulants (DOACs), there were no differences in DY, complications or Hb values compared with non-DOAC patients. CONCLUSION VCE and DBE play a pivotal role in the diagnostic and therapeutic approach to SSBB, having a high clinical impact even in patients treated with DOACs.

Abstract
BACKGROUND The incidence of internal hernias has recently increased in concordance with the popularization of laparoscopic surgery. Of particular concern are internal hernias occurring in Petersen's space, a space that is surgically created after treatment for gastric cancer and obesity. These hernias cause devastating sequelae, such as massive intestinal necrosis, fatal Roux limb necrosis, and superior mesenteric vein thrombus. In addition, protein-losing enteropathy (PLE) is a rare syndrome involving gastrointestinal protein loss, although its relationship with internal Petersen’s hernias remains unknown.
CASE SUMMARY A 75-year-old man with a history of laparotomy for early gastric cancer developed Petersen's hernia 1 year and 5 mo after surgery. He was successfully treated by reducing the incarcerated small intestine and closure of Petersen’s defect without resection of the small intestine. Approximately 3 mo after his surgery for Petersen’s hernia, he developed bilateral leg edema and hypoalbuminemia. He was diagnosed with PLE with an alpha-1 antitrypsin clearance of 733 mL/24 h. Double-balloon enteroscopy revealed extensive jejunal ulceration as the etiology, and it facilitated minimum bowel resection. Pathological analysis showed extensive jejunal ulceration and collagen hyperplasia with nonspecific inflammation of all layers without lymphangiectasia, lymphoma, or vascular abnormalities. His postoperative course was unremarkable, and his bilateral leg edema and hypoalbuminemia improved after 1 mo. There was no relapse over the 5-year follow-up period.
CONCLUSION PLE and extensive jejunal ulceration may occur after Petersen's hernia. Double-balloon enteroscopy helps identify and resect these lesions.

Abstract
Background Capsule endoscopy (CE) is the first line for evaluation of patients with obscure gastrointestinal bleeding. A wide range of small intestinal vascular lesions with different hemorrhagic potential are frequently found in these patients. Nevertheless, reading CE exams is time-consuming and prone to errors. Convolutional neural networks (CNN) are artificial intelligence tools with high performance levels in image analysis. This study aimed to develop a CNN-based model for identification and differentiation of vascular lesions with distinct hemorrhagic potential in CE images. Methods The development of the CNN was based on a database of CE images. This database included images of normal small intestinal mucosa, red spots, and angiectasia/varices. The hemorrhagic risk was assessed by Saurin's classification. For CNN development, 11,588 images (9525 normal mucosa, 1026 red spots, and 1037 angiectasia/varices) were ultimately extracted. Two image datasets were created for CNN training and testing. Results The network was 91.8% sensitive and 95.9% specific for detection of vascular lesions, providing accurate predictions in 94.4% of cases. In particular, the CNN had a sensitivity and specificity of 97.1% and 95.3%, respectively, for detection of red spots. Detection of angiectasia/varices occurred with a sensitivity of 94.1% and a specificity of 95.1%. The CNN had a frame reading rate of 145 frames/sec. Conclusions The developed algorithm is the first CNN-based model to accurately detect and distinguish enteric vascular lesions with different hemorrhagic risk. CNN-assisted CE reading may improve the diagnosis of these lesions and overall CE efficiency.

Abstract
OBJECTIVE Capsule endoscopy (CE) is pivotal for evaluation of small bowel disease. Obscure gastrointestinal bleeding most often originates from the small bowel. CE frequently identifies a wide range of lesions with different bleeding potentials in these patients. However, reading CE examinations is a time-consuming task. Convolutional neural networks (CNNs) are highly efficient artificial intelligence tools for image analysis. This study aims to develop a CNN-based model for identification and differentiation of multiple small bowel lesions with distinct haemorrhagic potential using CE images. DESIGN We developed, trained, and validated a denary CNN based on CE images. Each frame was labelled according to the type of lesion (lymphangiectasia, xanthomas, ulcers, erosions, vascular lesions, protruding lesions, and blood). The haemorrhagic potential was assessed by Saurin's classification. The entire dataset was divided into training and validation sets. The performance of the CNN was measured by the area under the receiving operating characteristic curve, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). RESULTS A total of 53 555 CE images were included. The model had an overall accuracy of 99%, a sensitivity of 88%, a specificity of 99%, a PPV of 87%, and an NPV of 99% for detection of multiple small bowel abnormalities and respective classification of bleeding potential. CONCLUSION We developed and tested a CNN-based model for automatic detection of multiple types of small bowel lesions and classification of the respective bleeding potential. This system may improve the diagnostic yield of CE for these lesions and overall CE efficiency.

Abstract
Introduction Capsule endoscopy has revolutionized the management of patients with obscure gastrointestinal bleeding. Nevertheless, reading capsule endoscopy images is time-consuming and prone to overlooking significant lesions, thus limiting its diagnostic yield. We aimed to create a deep learning algorithm for automatic detection of blood and hematic residues in the enteric lumen in capsule endoscopy exams. Methods A convolutional neural network was developed based on a total pool of 22,095 capsule endoscopy images (13,510 images containing luminal blood and 8,585 of normal mucosa or other findings). A training dataset comprising 80% of the total pool of images was defined. The performance of the network was compared to a consensus classification provided by 2 specialists in capsule endoscopy. Subsequently, we evaluated the performance of the network using an independent validation dataset (20% of total image pool), calculating its sensitivity, specificity, accuracy, and precision. Results Our convolutional neural network detected blood and hematic residues in the small bowel lumen with an accuracy and precision of 98.5 and 98.7%, respectively. The sensitivity and specificity were 98.6 and 98.9%, respectively. The analysis of the testing dataset was completed in 24 s (approximately 184 frames/s). Discussion/Conclusion We have developed an artificial intelligence tool capable of effectively detecting luminal blood. The development of these tools may enhance the diagnostic accuracy of capsule endoscopy when evaluating patients presenting with obscure small bowel bleeding.

Abstract
The current study evaluated the application of small-bowel capsule endoscopy (SBCE) in SARS-CoV-2-infected patients with suspected small bowel bleeding. We analyzed the clinical characteristics, SBCE procedures, examination results, and treatment for cases of suspected small bowel bleeding in two patients with critical COVID-19. SBCE showed active spotting bleeding in the jejunum and ileum with no identifiable lesions in case 1, while multiple small bowel ulcers were detected in case 2. Two patients had relevant changes in their management plans and received specific treatment based on SBCE findings. In summary, SBCE proved to be a non-invasive diagnostic tool for critical COVID-19 patients with suspected small bowel bleeding.

Abstract
OBJECTIVE We have previously revealed the clinical factors and genetic polymorphisms associated with gastrointestinal mucosal injury and bleeding, induced by low-dose aspirin (LDA). After performing genome-wide analysis of single nucleotide polymorphisms (SNPs) using the Drug Metabolizing Enzymes and Transporters (DMET) system among drug metabolism and transporter genes, certain SNPs were found to increase the risk for LDA-induced small bowel bleeding. The aim of this study was to identify the SNPs involved in LDA-induced small bowel bleeding. SUBJECTS AND METHODS Subjects were patients taking LDA, with small bowel bleeding diagnosed using capsule endoscopy. We investigated the clinical characteristics and the previously identified SNPs, that were examined by the DNA direct sequence method. RESULTS 56 patients with bleeding and 410 controls taking LDA were enrolled. The risk factors associated with small bowel bleeding included smoking, cerebrovascular diseases, chronic renal failure, non-steroidal anti-inflammatory drug (NSAID) or anticoagulants combination, and two SNPs (CYP4F11 20043G>A (D446N) rs1060463, GSTP1 313A>G rs1695). After propensity score matching, GSTP1 rs1695 was significantly associated with small bowel bleeding. CONCLUSION The GSTP1 SNP may be a predictive marker for small bowel bleeding among patients taking LDA.

Abstract
BACKGROUND Capsule enteroscopy (CE) and 99mTc Red blood cell (RBC) scintigraphy are frequently used tests in the investigation of obscure gastrointestinal bleeding (OGIB). There is a scarcity of data comparing both diagnostic modalities. This study aims to assess the performance of CE and scintigraphy for the diagnosis of OGIB. METHODS Patients who underwent CE and scintigraphy for OGIB were selected and analyzed retrospectively. The hemorrhagic potential of CE findings was rated using Saurin's classification. The concordance between both diagnostic techniques for bleeding detection and localization was analyzed. RESULTS Eighty-five patients (62% female), with a median age of 63 years, were included. Capsule enteroscopy identified 37 patients (43%) with high hemorrhagic potential (P2) lesions. Most scintigraphy exams were positive for gastrointestinal bleeding (82%). No concordance was found between the detection of lesions with hemorrhagic potential in CE and scintigraphy (kappa <0). The distribution of P0, P1, and P2 findings was similar in patients with positive or negative scintigraphy (p=0.526). There was no agreement regarding the location of P2 findings in CE and the bleeding detected in the scintigraphy (kappa <0). Patients with P2 lesions had significantly lower median levels of hemoglobin (p=0.002) at presentation. No significant difference was found in hemoglobin values between patients with positive or negative scintigraphy (p=0.058). CONCLUSION Significant diagnostic discrepancy was observed between CE and scintigraphy. The findings of CE correlated better with hemoglobin values at presentation than the scintigraphy results. Therefore, scintigraphy didn't appear to be useful in the diagnostic workup of OGIB. .

Abstract
BACKGROUND AND AIMS Although sporadic duodenal and/or ampullary adenomas (DAs) are uncommon, they are increasingly diagnosed during upper endoscopy. These patients have a 3- to 7-fold increased risk of colonic neoplasia compared with the normal population. It is unknown, however, whether they also have an increased risk of additional small-bowel (SB) polyps. Our aim was to establish the prevalence of SB polyps in patients with DA. METHODS In a single-center, prospective study, we used video capsule endoscopy (VCE) to investigate the prevalence of SB polyps in patients with a DA compared with patients undergoing VCE for obscure GI bleeding or iron deficiency anemia. RESULTS Over 25 months, 201 patients were enrolled in the study; the mean age was 65 years and 47% were male. There were 101 control patients and 100 cases of DA cases (mean size, 30 mm (range, 10-80 mm)). We did not identify any SB polyps in either group. Colonic polyps were found more frequently in the DA group compared with controls (61% versus 37%, respectively (P =.002)). Advanced colonic adenoma (high-grade dysplasia, >10 mm, villous histology) were found in 18% of the DA group and 5% of the control group (P =.018). CONCLUSION Our data suggest that patients with a DA are not at risk for additional SB polyps and hence do not support screening with VCE. However, colonoscopy is mandatory due to the significantly higher risk of colonic polyps including advanced adenomas. (Clinical trial registration number: NCT02470416.).

Abstract
BACKGROUND Capsule endoscopy has been considered the first-line approach for the investigation of obscure gastro-intestinal bleeding since its approval in 2001. Our study aims to evaluate the diagnostic yield of capsule endoscopy in the investigation of this condition. We also analyse the incidence of non-small-bowel lesions missed after conventional endoscopy and later detected by capsule endoscopy in patients with suspected obscure bleeding. METHODS A total of 290 patients with negative conventional endoscopy referred to our centre to undergo a capsule endoscopy examination for the investigation of obscure gastro-intestinal bleeding. We considered as non-small-bowel lesions those outside the tract between the second duodenal portion and the ileocecal valve. We also looked for actively bleeding lesions at the time of the exam. RESULTS Intestinal preparation was good, adequate or poor in 74.1%, 8.4%, and 17.5% of the tests, respectively. Caecum was reached in 92.4%. Capsule retention occurred in 0.7%. Mean small bowel transit time was 5hours and 13minutes. Diagnostic yield was 73.8%. An actively bleeding lesion was noticed in 39.3% of positive tests. Capsule endoscopy revealed clinically significant non-small-bowel lesions missed at gastroscopy or colonoscopy in 30.3% of patients, 43.2% of which were bleeding. CONCLUSIONS Capsule endoscopy has high diagnostic yield and safety in the investigation of obscure gastro-intestinal bleedings. Given the high percentage of non-small-bowel lesions detected, it may be appropriate to consider an endoscopic second look before performing a capsule endoscopy study.

Abstract
Small bowel carcinoid tumor is a difficult to diagnose entity that can present an aggressive clinical course even if they are small in size. The diagnosis based on tumor markers and imaging tests is limited, but the combination of capsule endoscopy followed by enteroscopy when the carcinoid tumor is suspected, has been shown to be useful for its early diagnosis, as well as for reaching a thorough study of the small bowel. We present a clinical case of two small synchronous carcinoid tumors of the ilium that were diagnosed by using this strategy.

Abstract
Systemic sclerosis (SSc) has the potential to affect any component of the gastrointestinal (GI) tract. GI involvement in SSc is a leading cause of morbidity and overall decreased quality of life in this patient population, identifying a need for a concise approach to work-up. This literature review aims to present a systematic, anatomical approach and differential diagnosis of GI involvement in SSc for the general internist and rheumatologist. Each component of the luminal GI tract has its own specified section, beginning with a review of a clinical approach to diagnosis that includes a differential for clinicians to consider, followed by a discussion of the literature surrounding objective evaluation of these conditions (i.e. serologic studies, imaging, endoscopy). Additionally there is a focused discussion on an approach to GI bleeding in the patient with SSc.

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
INTRODUCTION studies have examined the agreement between capsule endoscopy and double-balloon enteroscopy, with varying results. The aim of this study was to identify factors that predict the visualization of lesions in the small bowel by double-balloon enteroscopy after a positive capsule endoscopy. METHODS a retrospective, observational and comparative study was performed that evaluated patients that underwent double-balloon enteroscopy after a positive capsule endoscopy, between January 2017 and August 2019. The data studied included demographics, indications, comorbidities and the results of capsule endoscopy and double-balloon enteroscopy, which were evaluated by multiple logistic regression. RESULTS 91 patients were included (age 58 ± 16.5 years, 53 female). Sixty-two double-balloon enteroscopy (68.1 %) found the same lesions as capsule endoscopy. Predictive factors for a positive double-balloon enteroscopy were multiple lesions (OR 8.10, 1.50-43.78; p = 0.015) and < 15 days between both studies (OR 5.31, 1.19-23.66; p=0.029). In the subgroup of patients with small bowel bleeding (70 patients), the results of 46 double-balloon enteroscopies (65.7 %) agreed with the capsule endoscopy. Predictive factors in this group were multiple lesions (OR 13.51, 1.78-102.22; p = 0.012), < 15 days between both studies (OR 13.51, 1.78-102.22; p = 0.012), > 60 years of age (OR 7.45, 1.51-36.75; p = 0.014) and ulcers (OR 4.67, 1.08-20.22; p = 0.039). CONCLUSIONS predictive factors for a positive double-balloon enteroscopy after a positive capsule endoscopy were multiple lesions and < 15 days between both procedures. In patients with small bowel bleeding, age over 60 years and the presence of ulcers were also predictive factors.

Abstract
Hemangioma of the small intestine is a rare vascular malformation which mostly presents as occult gastrointestinal bleeding and iron-deficiency anemia. Patients are often asymptomatic except of fatigue due to anemia. Hemangiomas can arise anywhere in the luminal gastrointestinal tract, with jejunum as the most commonly involved site. They are very hard to recognize mostly due to their localization. Video capsule endoscopy and balloon-assisted enteroscopy have very much improved preoperative diagnostics and made major contribution to establishing the diagnosis - which was very difficult in the past and almost all cases were diagnosed during or after the operation. Surgical resection is still the conventional treatment modality, although with the improvement of endoscopic therapeutic interventions (endoscopic mucosal resection, argon-plasma coagulation) there are more therapeutic possibilities.

Abstract
Capsule endoscopy (CE) has proved to be a powerful tool in the diagnosis and management of small bowel disorders since its introduction in 2001. However, white light imaging (WLI) is the principal technology used in clinical CE at present, and therefore, CE is limited to mucosal inspection, with diagnosis remaining reliant on visible manifestations of disease. The introduction of WLI CE has motivated a wide range of research to improve its diagnostic capabilities through integration with other sensing modalities. These developments have the potential to overcome the limitations of WLI through enhanced detection of subtle mucosal microlesions and submucosal and/or transmural pathology, providing novel diagnostic avenues. Other research aims to utilize a range of sensors to measure physiological parameters or to discover new biomarkers to improve the sensitivity, specificity and thus the clinical utility of CE. This multidisciplinary Review summarizes research into non-WLI CE devices by organizing them into a taxonomic structure on the basis of their sensing modality. The potential of these capsules to realize clinically useful virtual biopsy and computer-aided diagnosis (CADx) is also reported.

Abstract
AIM Double-balloon enteroscopy (DBE) is a useful tool for the evaluation and treatment of small bowel disease. Limited clinical data are available regarding the indications, clinical findings and safety associated with the use of DBE in children. The aim of this study is to investigate the utility and safety of DBE in children. METHODS A total of 72 DBE procedures were performed on 61 children at the Sixth Affiliated Hospital, Sun Yat-sen University, between 1 April 2013 and 31 December 2017. The clinical data were analysed retrospectively. RESULTS DBE was attempted 72 times in 61 children (45 boys and 16 girls) of an age range between 6 and 14 years (mean age: 11.9 years). The most common indication for DBE was occult gastrointestinal bleeding and abdominal pain. The positive rate of abnormal findings was 77.5% (55/72). Most children showed non-specific enteritis and Crohn's disease. Eight children underwent successful therapeutic enteroscopy. No serious complication was observed in any child in this case series. CONCLUSION DBE can be a useful diagnostic and therapeutic tool for small bowel disorders in children.
