Supporting self-management for patients with Interstitial Lung Diseases: Utility and acceptability of digital devices.

INTRODUCTION: Patients diagnosed with Interstitial Lung Diseases (ILD) use devices to self-monitor their health and well-being. Little is known about the range of devices, selection, frequency and terms of use and overall utility. We sought to quantify patients' usage and experiences with home digital devices, and further evaluate their perceived utility and barriers to adaptation. METHODS: A team of expert clinicians and patient partners interested in self-management approaches designed a 48-question cross-sectional electronic survey; specifically targeted at individuals diagnosed with ILD. The survey was critically appraised by the interdisciplinary self-management group at Royal Devon University Hospitals NHS Foundation Trust during a 6-month validation process. The survey was open for participation between September 2021 and December 2022, and responses were collected anonymously. Data were analysed descriptively for quantitative aspects and through thematic analysis for qualitative input. RESULTS: 104 patients accessed the survey and 89/104 (86%) reported a diagnosis of lung fibrosis, including 46/89 (52%) idiopathic pulmonary fibrosis (IPF) with 57/89 (64%) of participants diagnosed >3 years and 59/89 (66%) female. 52/65(80%) were in the UK; 33/65 (51%) reported severe breathlessness medical research council MRC grade 3-4 and 32/65 (49%) disclosed co-morbid arthritis or joint problems. Of these, 18/83 (22%) used a hand- held spirometer, with only 6/17 (35%) advised on how to interpret the readings. Pulse oximetry devices were the most frequently used device by 35/71 (49%) and 20/64 (31%) measured their saturations more than once daily. 29/63 (46%) of respondents reported home-monitoring brought reassurance; of these, for 25/63 (40%) a feeling of control. 10/57 (18%) felt it had a negative effect, citing fluctuating readings as causing stress and 'paranoia'. The most likely help-seeking triggers were worsening breathlessness 53/65 (82%) and low oxygen saturation 43/65 (66%). Nurse specialists were the most frequent source of help 24/63 (38%). Conclusion: Patients can learn appropriate technical skills, yet perceptions of home-monitoring are variable; targeted assessment and tailored support is likely to be beneficial.

Small-Bowel Angioectasias: Are They Responsible for a Real Impact on Survival?

Introduction: This study aimed to evaluate the effect of small-bowel angioectasia on survival, given the hypothesis that angioectasia might be an independent risk factor of frailty and poor outcomes. Methods: In this retrospective cohort study, all patients undergoing small-bowel capsule endoscopy between 2010 and 2013 for obscure gastrointestinal bleeding from a Portuguese tertiary centre were included. Follow-up started after capsule endoscopy and ended upon death or end of the study (November 2020). Survival analysis was performed using a Cox proportional-hazards model, in order to analyse the effect of small-bowel angioectasia on survival as well as potentially confounding factors (age, vascular diseases and chronic kidney disease). Results: A total of 176 patients were included in this study (50.6% male), with a median age of 68.5 years (IQR 24). The median follow-up was 7 years (IQR 4), during which 67 (38.1%) patients died. Seventy-three (41.5%) patients had at least one small-bowel angioectasia on capsule endoscopy. On multivariate Cox regression analysis, only age, peripheral arterial disease, history of previous mesenteric ischaemia and chronic kidney disease were independent risk factors of death. The presence of small-bowel angioectasia did not affect survival in this analysis (HR 1.30; 95% CI 0.75-2.23; p = 0.35). Conclusion: In this retrospective cohort study, some comorbidities and age were independent predictors of poor survival. The presence of small-bowel angioectasia per se did not affect survival.

Introdução: Este estudo pretendeu avaliar a influência das angiectasias do intestino delgado na sobrevida, dada a hipótese de que as angiectasias pudessem constituir um fator de risco independente para fragilidade e outcomes adversos. Métodos: Os autores incluíram neste estudo de coorte retrospetivo todos os doentes submetidos a cápsula endoscópica entre 2010 e 2013 por hemorragia digestiva obscura num centro português terciário. O followup iniciou-se após a realização da cápsula e terminou aquando da morte ou fim do estudo (Novembro de 2020). A análise da sobrevida foi realizada através de um modelo de regressão de Cox, no sentido de analisar o efeito na sobrevida das angiectasias do intestino delgado e de potenciais fatores confundidores (idade, doenças vasculares e doença renal crónica). Resultados: Neste estudo foram incluídos 176 doentes (50.6% do sexo masculino), com uma idade mediana de 68.5 anos (IQR 24). O tempo de follow-up mediano foi de 7 anos (IQR 4), durante o qual se verificaram 67 (38.1%) óbitos. 73 (41.5%) dos doentes apresentavam pelo menos uma angiectasia no intestino delgado. Na análise de sobrevida, apenas a idade, doença arterial periférica, história prévia de isquemia mesentérica e doença renal crónica foram fatores de risco independentes de mortalidade. A presença de angiectasias no intestino delgado não afetou a sobrevida nesta amostra (HR 1,30; 95% CI 0,75­2,23; p = 0.35). Conclusão: Neste estudo de coorte retrospetivo, algumas co-morbilidades e a idade foram fatores de risco independentes de mortalidade. A presença de angiectasias no intestino delgado, per se, não afetou a sobrevida.

Patient perspectives on home-spirometry in interstitial lung disease: a qualitative co-designed study.

BACKGROUND: Opportunities for home-monitoring are increasing exponentially. Home- spirometry is reproducible and reliable in interstitial lung disease (ILD), yet patients' experiences are not reported. Given the morbidity and mortality associated with ILDs, maintaining health-related quality-of-life is vital. We report our findings from a codesigned, qualitative study capturing the perspectives and experiences of patients using home-spirometry in a UK regional ILD National Health Service England (NHSE) commissioned service. METHODS: Patients eligible for home-spirometry as routine clinical care, able to give consent and able to access a smart phone were invited to participate. In-depth, semistructured interviews were conducted at serial time points (baseline, 1, 3 and 6 months), recorded, transcribed and analysed thematically. RESULTS: We report on the experiences of 10 recruited patients (8 males; median age 66 years, range 50-82 years; 7 diagnosed with idiopathic pulmonary fibrosis, 3 other ILDs) who generally found spirometry convenient and easy to use, but their relationships with forced vital capacity results were complex. Main themes emerging were: (1) anticipated benefits-to identify change, trigger action and aid understanding of condition; (2) needs-clinical oversight and feedback, understanding of results, ownership, need for data and a need 'to know'; (3) emotional impact-worry, reassurance, ambivalence/conflicting feelings, reminder of health issues, indifference; (4) ease of home-spirometry-simplicity, convenience and (5) difficulties with home-spirometry-technical issues, technique, physical effort. CONCLUSION: Home-spirometry has many benefits, but in view of the potential risks to psychological well-being, must be considered on an individual basis. Informed consent and decision-making are essential and should be ongoing, acknowledging potential limitations as well as benefits. Healthcare support is vital.

Concordance of Dye-Spraying Chromoendoscopy and Virtual Chromoendoscopy for Colonic Dysplasia Detection in Longstanding Inflammatory Bowel Disease.

BACKGROUND/AIMS: In the past, dye-spraying chromoendoscopy was the technique of choice for colonic surveillance in patients with long-standing extensive inflammatory bowel disease. Recent evidence suggests that virtual chromoendoscopy is an equally acceptable technique. MATERIALS AND METHODS: Eleven gastroenterologists were given a survey with 20 pairs of pictures from inflammatory bowel disease surveillance colonoscopies (10 with nondysplastic lesions, 5 with dysplastic lesions, and 5 with no lesions). Each pair contained the same image captured during colonoscopy using indigo carmine and narrow-band imaging. For each picture, the gastroenterologist assessed the presence/absence of lesion and, when a lesion was identified, assessed the presence/absence of dysplasia and delineated its margins. To compare lesion and dysplasia detection between techniques, sensitivity, specificity, and interobserver agreement were calculated. The chi-square test was used to assess the accuracy of margins delineation. RESULTS: When assessing lesion and dysplasia detection, similar sensitivity and specificity values were obtained for both techniques. Interobserver agreement analysis revealed that dye-spraying chromoendoscopy and virtual chromoendoscopy had a moderate agreement in lesion detection but, for dysplasia detection, dye-spraying chromoendoscopy had a slight agreement [K = 0.11 (0.03-0.18), P < .01] and virtual chromoendoscopy a fair agreement [K = 0.30 (0.22-0.37), P < .01]. Margin delineation was similar between techniques. CONCLUSION: Sensitivity and specificity for lesion and dysplasia detection, as well as the accuracy of margins delineation, were similar between dye-spraying chromoendoscopy and virtual chromoendoscopy. Interobserver agreement for dysplasia detection was suboptimal in both techniques; however, it was superior when using virtual chromoendoscopy. These findings suggest that virtual chromoendoscopy constitutes a valid alternative for dysplasia screening in inflammatory bowel disease.

Capsule Enteroscopy Using the Mirocam® versus OMOM® Systems: A Matched Case-Control Study.

Although several devices are available for small bowel capsule endoscopy, few studies have compared their visualization quality and diagnostic yield, despite users reporting subjective differences between them. This study aims to compare two widely used systems (Mirocam® MC1600 and OMOM® HD). Patients who underwent OMOM® HD capsule enteroscopy between August 2022 and February 2023 were prospectively included consecutively (cases). Controls were retrospectively selected from a database of patients who underwent Mirocam® MC1600 enteroscopy between March 2018 and July 2022 in a 1:1 ratio. Controls were matched for potential confounders (age, sex, indication, hospitalization, comorbidities, and opioid prescription). The small bowel cleanliness (global and divided by tertiles), the diagnostic yield (positive findings) and the transit times (TT) were compared. Overall, 214 patients were included (107:107). Global bowel preparation was similar between the OMOM® and Mirocam® groups. However, the average scores for each tertile were significantly higher when the OMOM® HD capsule was used (p < 0.05). Small bowel TT was shorter for OMOM® HD (265 ± 118 versus 307 ± 87 min, p = 0.020), while the diagnostic yield (55.0%) and relative distribution of lesions were similar. This study suggests that capsule characteristics, namely resolution, and illumination, systematically interfere with the perception of preparation quality. However, this did not affect the diagnostic yield.

Critical Analysis of the Applicability of Small Bowel Capsule Endoscopy Performance Measures among 2 Portuguese Centers with Different Capsule Endoscopy Platforms.

Introduction: The European Society of Gastrointestinal Endoscopy (ESGE) identified the need to benchmark the quality of small bowel capsule endoscopy (SBCE) and produced a set of performance measures (PM). The aim of this study is to critically evaluate the accordance of the PM for SBCE in two Portuguese centers with different SBCE platforms. Methods: The authors conducted a cross-sectional analysis of consecutive SBCE performed in an 18-month period in 2 Portuguese centers that used two different SBCE platforms Mirocam® (IntroMedic, Seoul, South Korea) and PillCam® (Medtronic, Yokneam, Israel). A total of 10 PM (6 key, 4 minor) were evaluated and compared between the 2 centers. Results: A total of 493 SBCE were included. The minimum standard established by ESGE was reached in 3/6 key PM (complete visualization, lesion detection rate, and capsule retention rate), and none of the 4 minor PM. PM compliance significantly differed between the 2 centers: complete small bowel visualization 95.9 and 90% (p = 0.01), diagnostic yield 50.6 and 63% (p = 0.005), adequate small bowel cleansing level according to Brotz scale 69.54 and 84.6% (p ≤ 0.001), patients with high risk of capsule retention offered a patency capsule 4.2 and 73% (p ≤ 0.001), respectively. Conclusion: This study highlights and critically discusses technical and organizational issues that should be considered in defining more realistic PM thresholds, aiming to improve SBCE quality.

Introdução: A Sociedade Europeia de Endoscopia Digestiva (ESGE) identificou a necessidade de avaliar a qualidade da enteroscopia por videocápsula (EVC) e produziu um conjunto de medidas de desempenho (MD). O objetivo deste estudo é avaliar criticamente a concordância das medidas de desempenho de EVC em dois centros portugueses com diferentes plataformas de EVC. Métodos: Análise transversal de EVC consecutivas realizadas em 2 centros portugueses, com diferentes plataformas de EVC Mirocam® (IntroMedic, Seul, Coreia) e PillCam® (Medtronic, Yokneam, Israel), respetivamente. Um total de 10 medidas de desempenho (6 principais, 4 minor) foram avaliadas e comparadas entre os 2 centros. Resultados: Foram incluídas 493 EVC. O standard mínimo estabelecido pela ESGE foi alcançado em 3/6 MD principais (visualização completa, taxa de detecção de lesões e taxa de cápsula retida), e nenhum nas quatro MD minor. O cumprimento das MD diferiu significativamente entre os 2 centros: visualização completa do intestino delgado 95,9 e 90% (p = 0,01), taxa de deteção de lesões 50,6% e 63% (p = 0,005), adequada preparação do intestino delgado de acordo com a escala de Brotz 69,54 e 84,6% (p ≤ 0,001), doentes com alto risco de retenção da cápsula a quem foi oferecida cápsula de patência 4,2 e 73% (p ≤ 0,001), respectivamente. Introdução: Este estudo destaca e discute criticamente questões técnicas e organizacionais que devem ser consideradas na definição de limiares de MD mais realistas, com o objetivo de melhorar a qualidade da EVC.

Validation and Application of Predictive Models for Inadequate Bowel Preparation in Colonoscopies in a Tertiary Hospital Population.

Background: Bowel preparation is a major quality criterion for colonoscopies. Models developed to identify patients with inadequate preparation have not been validated in external cohorts. We aim to validate these models and determine their applicability. Methods: Colonoscopies between April and November 2019 were retrospectively included. Boston Bowel Preparation Scale ≥2 per segment was considered adequate. Insufficient data, incomplete colonoscopies, and total colectomies were excluded. Two models were tested: model 1 (tricyclic antidepressants, opioids, diabetes, constipation, abdominal surgery, previous inadequate preparation, inpatient status, and American Society of Anesthesiology [ASA] score ≥3); model 2 (co-morbidities, tricyclic antidepressants, constipation, and abdominal surgery). Results: We included 514 patients (63% males; age 61.7 ± 15.6 years), 441 with adequate preparation. The main indications were inflammatory bowel disease (26.1%) and endoscopic treatment (24.9%). Previous surgery (36.2%) and ASA score ≥3 (23.7%) were the most common comorbidities. An ASA score ≥3 was the only identified predictor for inadequate preparation in this study (p < 0.001, OR 3.28). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of model 1 were 60.3, 64.2, 21.8, and 90.7%, respectively. Model 2 had a sensitivity, specificity, PPV, and NPV of 57.5, 67.4, 22.6, and 90.5%, respectively. The AUC for the ROC curves was 0.62 for model 1, 0.62 for model 2, and 0.65 for the ASA score. Conclusions: Although both models accurately predict adequate bowel preparation, they are still unreliable in predicting inadequate preparation and, as such, new models, or further optimization of current ones, are needed. Utilizing the ASA score might be an appropriate approximation of the risk for inadequate bowel preparation in tertiary hospital populations.

Introdução: A preparação intestinal é um dos principais critérios de qualidade na colonoscopia. Modelos desenvolvidos para identificar doentes com preparação inadequada nunca foram validados em coortes externas. Pretendemos validar esses modelos e determinar sua aplicabilidade clínica. Métodos: Colonoscopias entre abril-novembro/2019 foram incluídas retrospectivamente. A Escala de Preparação Intestinal de Boston ≥2 por segmento foi considerada adequada. Dados insuficientes, colonoscopias incompletas e colectomias totais foram excluídos. Dois modelos foram testados: modelo 1 (antidepressivos tricíclicos, opióides, diabetes, obstipação, cirurgia abdominal, preparação prévia inadequada, internamento e American Society of Anesthesiology [ASA] ≥3); modelo 2 (comorbilidades, antidepressivos tricíclicos, obstipação e cirurgia abdominal). Resultados: Foram incluídos 514 doentes (63% homens; idade 61.7 ± 15.6), 441 com preparação adequada. As principais indicações foram doença inflamatória intestinal (26.1%) e tratamento endoscópico (24.9%). Cirurgias anteriores (36.2%) e ASA ≥3 (23.7%) foram as comorbilidades mais comuns. Um score ASA ≥3 foi o único fator de risco identificado para preparação inadequada (p < 0.001, OR 3.28). A sensibilidade, especificidade, valor preditivo positivo (VPP) e valor preditivo negativo (VPN) do modelo 1 foi de 60.3, 64.2, 21.8 e 90.7%. O modelo 2 apresentou sensibilidade, especificidade, VPP e VPN de 57.5, 67.4, 22.6 e 90.55%. A AUC para a curva ROC foi de 0.62 para o modelo 1, 0.62 para o modelo 2 e 0.65 para o score ASA. Conclusões: Embora ambos os modelos sejam eficazes a prever preparação intestinal adequada, não se verifica o mesmo para a preparação inadequada e como tal, novos modelos ou otimização dos atuais são ainda necessários. Utilizar o score ASA pode ser uma aproximação adequada do risco de preparação intestinal inadequada em populações de hospitais terciários.

Very High Yield of Urgent Small-Bowel Capsule Endoscopy for Ongoing Overt Suspected Small-Bowel Bleeding Irrespective of the Usual Predictive Factors.

Evidence for an urgent approach to ongoing overt suspected small-bowel bleeding (SSBB) is scarce. We aimed to analyze our series of urgent small-bowel capsule endoscopies (SBCEs) for ongoing overt SSBB and to identify factors associated with positive findings and outcomes. A retrospective study of all SBCEs performed in the first 48 h after admission for overt SSBB between January 2006 and February 2022 was performed. Descriptive and inferential analyses (univariate and multivariable) were performed. Eighty-three urgent SBCEs were performed for overt SSBB. Patients were mostly men (69.2%, median age 68) and were followed for a median of 58.2 months (range 5-176). The diagnostic yield was 80.7%; in 60.2%, blood was detected in the small bowel (SB), while in 50.6%, a bleeding lesion was identified, mostly angioectasia. Patients with diabetes mellitus or taking NSAIDs were more prone to present SB findings, yet the explanatory power was low. Endoscopic or surgical treatments were performed in 28.9% and 19.3%, respectively, with the "non-conservative" therapeutic yield being 56.6%. Rebleeding occurred in 20.5% and was associated in the multivariable analysis with the female gender and anticoagulants use. This cohort of urgent SBCE, the largest from a European center, reinforces the usefulness of SBCE for ongoing overt SSBB management. This prompt performance of this procedure is highly effective, regardless of patients' features.

Unexpected Small-Bowel Finding in Overt-Obscure Gastrointestinal Bleeding in a Patient with Neurofibromatosis Type 1 and Crohn's Disease.

Gastrointestinal stromal tumors (GIST) are the most frequent mesenchymal neoplasms affecting the gastrointestinal tract, and the small bowel is the second most frequent location. Approximately 5% of patients with GIST are not sporadic and have a familial autosomal dominant syndrome, such as neurofibromatosis type 1 (NF1). Gastrointestinal bleeding is a common presentation of GIST, and lesions such as submucosal tumors may be detected more readily by capsule endoscopy due to luminal impingement and overlying ulceration. Our report emphasizes the importance of small-bowel investigation in patients with Crohn's disease and NF1 presenting with recent overt bleeding.

Os tumores do estroma gastrointestinal (GIST) são as neoplasias mesenquimatosas que mais frequentemente afetam o trato gastrointestinal, e o intestino delgado é a segunda localização mais comum. Aproximadamente 5% dos GIST não são esporádicos e estão associados a uma síndrome autossómica dominante familiar, como a neurofibromatose tipo 1 (NF1). A hemorragia gastrointestinal é uma apresentação habitual dos GIST, e as lesões subepiteliais podem ser detectadas através da cápsula endoscópica devido à procidência luminal com ulceração subjacente em alguns casos. O nosso caso clínico enfatiza a importância da investigação do intestino delgado numa doente com doença de Crohn e NF1 que apresentou uma hemorragia gastrointestinal.

Readjustment of Capsule Endoscopy Protocols to the COVID-19 Pandemic in a Portuguese Tertiary Center.

BACKGROUND: The prevention of severe acute respiratory syndrome corona virus 2 transmission implies several social distancing mea- sures, imposing a change in the protocols of several hospital departments. Capsule endoscopy protocols changes were implemented and evaluated in a Portuguese tertiary center. METHODS: The authors compared pre-pandemic and peri-pandemic protocols, the latter favoring social distancing, used in MiroCam (IntroMedic, Seoul, Korea) and PillCam Crohn (Medtronic, Minneapolis, Minn, USA) capsule endoscopy, in a Gastroenterology Department of a tertiary center. All capsule endoscopy performed in outpatients between February 2018 and September 2020 was included. The authors compared significant lesions detection rate, completeness of procedure, adequate bowel preparation, complications rate, and patient satisfaction (through a brief phone call survey) among the protocols. RESULTS: This study included 70 MiroCam CE and 43 PillCam Crohn capsule endoscopy. No statistically significant differences concern- ing performance measures and patients satisfaction were found among the pre-pandemic protocol and the peri-pandemic protocol in MiroCam capsule endoscopy. Conversely, in PillCam Crohn capsule endoscopy, the rate of complete exams was significantly inferior in the peri-pandemic protocol (84.8% vs 50.0%, P = .036), with no other statistically significant differences in the remaining parameters. CONCLUSION: The performance measures and patient satisfaction were similar among the protocols analyzed for MiroCam capsule endoscopy. Thus, the readjustment of this capsule endoscopy system, which favors a reduction in hospital stay, appears to be a good alternative to the former protocols in this pandemic era. In contrast, the rate of complete exams was significantly inferior in the adapted protocol to the pandemic era for PillCam Crohn capsule endoscopy, disfavoring its maintenance in the clinical practice.

Expresión del ligando de proteína de muerte programada 1 (PD-L1) en linfoma de Hodgkin en pacientes peruanos / Programmed death-ligand 1 (PD-L1) expression in Hodgkin's lymphoma among Peruvian patients

RESUMEN Objetivo: Diversos estudios realizados sobre el linfoma de Hodgkin (LH) han determinado la expresión de la proteína de muerte programada (PD-L1) en las células de Reed-Sternberg-Hodgkin (HRS), con resultados variables. Esta proteína ha adquirido relevancia por su papel en la respuesta inmunitaria en las neoplasias malignas. El objetivo de este trabajo fue determinar la expresión inmunohistoquímica de PD-L1 en las HRS y su relación con la edad, sexo, estadio clínico y supervivencia global en una cohorte de pacientes peruanos. Materiales y métodos: Se evaluaron 25 biopsias de pacientes con diagnóstico de LH, lo que permitió determinar la expresión inmunohistoquímica de PD-L1 en las HRS en asociación con la sobrevida global (SG) y los datos clínicos de los pacientes. Resultados: Todos los casos mostraron expresión de PD-L1 en más del 1 %. No hubo diferencia estadística significativa en la SG cuando se comparó dos grupos de acuerdo con la expresión de PD-L1 con punto de corte en 50 %, ni tampoco con el estadio clínico (EC), la edad y el sexo. Conclusiones: Se ha encontrado una alta expresión de PD-L1 en los tumores con LH previos al tratamiento. No se ha encontrado asociación entre la expresión de PD-L1, la SG, la edad, el sexo o el EC. Son necesarios otros estudios con mayor cantidad de pacientes para reevaluar el impacto pronóstico de la expresión de esta proteína en LH.

ABSTRACT Objective: Various studies on Hodgkin's lymphoma (HL) have determined programmed death-ligand 1 (PD-L1) expression in Hodgkin and Reed-Sternberg (HRS) cells, with variable results. This protein has gained relevance for its role in the immune response in malignant neoplasms. This work aimed to determine PD-L1 immunohistochemical expression in HRS cells and its relationship with age, sex, clinical stage and overall survival (OS) in a cohort of Peruvian patients. Materials and methods: Twenty-five (25) biopsies from patients diagnosed with HL were assessed, which allowed determining PD-L1 immunohistochemical expression in HRS cells in relation to OS and clinical data of the patients. Results: All cases showed PD-L1 expression in more than 1 % of tumor cells. There was no statistically significant difference in OS when two groups were compared in terms of PD-L1 expression with a cut-off point of 50 %, clinical stage (CS), age and sex. Conclusions: High PD-L1 expression was found in pre-treatment HL tumors. No association was found between PD-L1 expression, OS, age, sex or CS. Further studies with a larger number of patients are necessary to reassess the prognostic impact of the expression of this protein in HL.

Digestive tract MALT lymphoma, an unusual location.

The authors describe a case of a rectal mucosa-associated lymphoid tissue lymphoma in a 78-year-old female patient, manifested as rectal bleeding. Despite being commonly diagnosed in the localized form, this patient had supradiaphragmatic involvement on disease staging. Immunochemotherapy was proposed due to the disseminated involvement and poorer prognosis.

Evaluation of a new composite score combining SPICE and protrusion angle scores to distinguish submucosal lesions from innocent bulges

Introduction and aim: in capsule endoscopy (CE), small bowel subepithelial lesions (SBSL) are difficult to distinguish from innocent mucosal protrusions. The SPICE score (smooth, protruding lesions index on CE) and a score that assesses the SBSL protrusion angle were developed. The aim of the study was to determine if a composite score is superior to the proposed models.Methods: all CE between 01/2010 and 12/2020 were included in the study if a smooth, round protruding lesion was identified. Both scores and a composite score (SPICE > 2 and angle < 90°) were calculated after video review. Mucosal protrusions were defined as SBSL if they had a histological/imaging diagnosis and innocent protrusions if otherwise. All patients without at least one appointment and an additional diagnostic exam after CE were excluded.Results: a total of 34 CE were included; 64.7 % were males, aged 65.4 ± 14.7 years. The most common indication for CE was anemia (52.9 %). SBSL was identified in 17 cases, with lipomas (14.7 %) being the most frequent diagnosis. Both the SPICE (AUROC 0.90, p < 0.001) and protrusion angle scores (AUROC 0.74, p = 0.019) accurately distinguished SBSL from innocent protrusions. Applying a 90° cut-off, the protrusion angle had a sensitivity of 52.9 % and specificity of 88.2 %. Applying a cut-off of > 2 points, the SPICE score has a sensitivity of 64.7 % and specificity of 94.2 %. The composite score had a sensitivity, specificity, positive and negative predictive value of 47.0 %, 100 %, 100 % and 65.4 %.Conclusion: we propose that additional follow-up investigation should always be undertaken in cases where both a SPICE > 2 and angle of < 90° are obtained, as the likelihood of SBSL is high.

Diagnostic and therapeutic yields of early capsule endoscopy and device-assisted enteroscopy in the setting of overt GI bleeding: a systematic review with meta-analysis.

BACKGROUND AND AIMS: Small-bowel capsule endoscopy (SBCE) and device-assisted enteroscopy (DAE) are essential in obscure GI bleeding (OGIB) management. However, the best timing for such procedures remains unknown. This meta-analysis aimed to compare, for the first time, diagnostic and therapeutic yields, detection of active bleeding and vascular lesions, recurrent bleeding, and mortality of "early" versus "nonearly" SBCE and DAE. METHODS: MEDLINE, ScienceDirect, and Cochrane Central Register of Controlled Trials were searched to identify studies comparing early versus nonearly SBCE and DAE. Random-effects meta-analysis was performed; reporting quality was assessed. RESULTS: From 1974 records, 39 were included (4825 patients). Time intervals for the early approach varied, within 14 days in SBCE and 72 hours in DAE. The pooled diagnostic and therapeutic yields of early DAE were superior to those of SBCE (7.97% and 20.89%, respectively; P < .05). The odds for active bleeding (odds ratio [OR], 5.09; I2 = 53%), positive diagnosis (OR, 3.99; I2 = 45%), and therapeutic intervention (OR, 3.86; I2 = 67%) were higher in the early group for SBCE and DAE (P < .01). Subgroup effects in diagnostic yield were only identified for the early group sample size. Our study failed to identify differences when studies were classified according to time intervals for early DAE (I2 < 5%), but the analysis was limited because of a lack of data availability. Lower recurrent bleeding in early SBCE and DAE was observed (OR, .40; P < .01; I2 = 0%). CONCLUSIONS: The role of small-bowel studies in the early evaluation of OGIB is unquestionable, impacting diagnosis, therapeutic intervention, and prognosis. Comparative studies are still needed to identify optimal timing.
