RESUMO
Motorized spiral enteroscopy (MSE) enhances small bowel exploration, but the optimal target population for this technique is unknown. We aimed to identify the target population for MSE by evaluating its efficacy and safety, as well as detecting predictors of efficacy. A prospective multicenter observational study was conducted at 9 tertiary hospitals in Spain, enrolling patients between June 2020-2022. Analyzed data included demographics, indications for the procedure, exploration time, depth of maximum insertion (DMI), technical success, diagnostic yield, interventional yield, and adverse events (AE) up to 14 days from enteroscopy. Patients with prior gastrointestinal surgery, unsuccessful balloon enteroscopy and small bowel strictures were analyzed. A total of 326 enteroscopies (66.6% oral route) were performed in 294 patients (55.1% males, 65 years ± 21). Prior abdominal surgery was present in 50% of procedures (13.5% gastrointestinal surgery). Lower DMI (162 vs 275 cm, p = 0.037) and diagnostic yield (47.7 vs 67.5%, p = 0.016) were observed in patients with prior gastrointestinal surgery. MSE showed 92.2% technical success and 56.9% diagnostic yield after unsuccessful balloon enteroscopy (n = 51). In suspected small bowel strictures (n = 49), the finding was confirmed in 23 procedures (46.9%). The total AE rate was 10.7% (1.8% classified as major events) with no differences related to prior gastrointestinal/abdominal surgery, unsuccessful enteroscopy, or suspected small bowel strictures. The study demonstrates that MSE has a lower diagnostic yield and DMI in patients with prior gastrointestinal surgery but is feasible after unsuccessful balloon-enteroscopy and in suspected small bowel strictures without safety concerns.

BACKGROUND: Capsule endoscopy reading is time consuming, and readers are required to maintain attention so as not to miss significant findings. Deep convolutional neural networks can recognise relevant findings, possibly exceeding human performances and reducing the reading time of capsule endoscopy. Our primary aim was to assess the non-inferiority of artificial intelligence (AI)-assisted reading versus standard reading for potentially small bowel bleeding lesions (high P2, moderate P1; Saurin classification) at per-patient analysis. The mean reading time in both reading modalities was evaluated among the secondary endpoints. METHODS: Patients aged 18 years or older with suspected small bowel bleeding (with anaemia with or without melena or haematochezia, and negative bidirectional endoscopy) were prospectively enrolled at 14 European centres. Patients underwent small bowel capsule endoscopy with the Navicam SB system (Ankon, China), which is provided with a deep neural network-based AI system (ProScan) for automatic detection of lesions. Initial reading was performed in standard reading mode. Second blinded reading was performed with AI assistance (the AI operated a first-automated reading, and only AI-selected images were assessed by human readers). The primary endpoint was to assess the non-inferiority of AI-assisted reading versus standard reading in the detection (diagnostic yield) of potentially small bowel bleeding P1 and P2 lesions in a per-patient analysis. This study is registered with ClinicalTrials.gov, NCT04821349. FINDINGS: From Feb 17, 2021 to Dec 29, 2021, 137 patients were prospectively enrolled. 133 patients were included in the final analysis (73 [55%] female, mean age 66·5 years [SD 14·4]; 112 [84%] completed capsule endoscopy). At per-patient analysis, the diagnostic yield of P1 and P2 lesions in AI-assisted reading (98 [73·7%] of 133 lesions) was non-inferior (p<0·0001) and superior (p=0·0213) to standard reading (82 [62·4%] of 133; 95% CI 3·6-19·0). Mean small bowel reading time was 33·7 min (SD 22·9) in standard reading and 3·8 min (3·3) in AI-assisted reading (p<0·0001). INTERPRETATION: AI-assisted reading might provide more accurate and faster detection of clinically relevant small bowel bleeding lesions than standard reading. FUNDING: ANKON Technologies, China and AnX Robotica, USA provided the NaviCam SB system.

Background and study aims In 2019, the European Society of Gastrointestinal Endoscopy (ESGE) created a working group to develop technical and quality standards for small-bowel capsule endoscopy (SBCE) to improve the daily practice of endoscopy services. They developed 10 quality parameters, which have yet to be tested in a real-life setting. Our study aimed to evaluate the accomplishment of the quality standards in SBCE established by the ESGE in several Spanish centers. Materials and methods An online survey of 11 multiple-choice questions related to the ESGE performance measures was sent to Spanish centers with experience in SBCE. In order to participate and obtain reliable data, at least 100 questionnaires had to be answered per center because that is the minimum number established by ESGE. Results 20 centers participated in the study, compiling 2049 SBCEs for the analysis. Only one of 10 performance measures (cecal visualization) reached the minimum standard established by the ESGE. In five of 10 performance measures (Indication, lesion detection rate, terminology, and retention rate) the minimum standard was nearly achieved. Conclusions Our study is the first multicenter study regarding SBCE quality performance measures in a real setting. Our results show that the minimum standard is hardly reached in most procedures, which calls into question their clinical applicability in real life. We suggest performing similar studies in other countries to evaluate whether there is a need for quality improvement programs or a need to reevaluate the minimum and target values published so far.
RESUMO
BACKGROUND AND AIMS: Small bowel (SB) capsule endoscopy (CE) is a first line procedure for exploring the SB. Endoscopic GastroIntestinal PlacemenT (EGIPT) of SB CE is sometimes necessary. While the experience of EGIPT is large in pediatric populations, we aimed to describe the safety, efficacy and outcomes of EGIPT of SB CE in adult patients. METHODS: The international CApsule endoscopy REsearch (iCARE) group set up a retrospective multicenter study. Patients over 18 year-old who underwent EGIPT of SB CE before May 2022 were included. Data were collected from medical records and capsule recordings. The primary endpoint was the technical success rate of the EGIPT procedures. RESULTS: 630 patients were included (mean age 62.5 years old, 55.9% female) from 39,565 patients (1.6%) issued from 29 centers. EGIPT technical success was achieved in 610 procedures (96.8%). Anesthesia (moderate/deep sedation or general anesthesia) and centers with intermediate or high procedure loads were independent factors of technical success. Severe adverse events occurred in three (0.5%) patients. When technically successful, EGIPT was associated with a high SB CE completion rate (84.4%) and with a substantial diagnostic yield (61.1%). Completion rate was significantly higher when the capsule was delivered in the SB compared to when delivered in the stomach. CONCLUSION: EGIPT of SB CE is highly feasible, safe and comes with high completion rate and diagnostic yield. When indicated, it should rather be performed under anesthesia and the capsule should be delivered in the duodenum rather than in the stomach, for better SB examination outcomes.

Device-assisted enteroscopy (DAE), balloon-assisted enteroscopy (BAE) in particular, has become a routine endoscopic procedure which has revolutionized our approach to small-bowel disease. Evidence demonstrating the efficacy and safety of BAE spans over 22-years of experience, making it an established pillar of minimally invasive care. The robust evidence for BAE's safety and efficacy has now been incorporated into international clinical guidelines, technical reviews, benchmarking performance measures and curricula. The more recently introduced motorized spiral enteroscopy (MSE) which had replaced the previous manual version, abruptly ended its 7-year stint in clinical practice, when it was withdrawn and recalled from the market by its manufacturing company in July 2023, due to several associated serious adverse events (including fatalities). This article, written by the original developer of double-balloon enteroscopy (DBE) and other recognized international experts and pioneers in this field, focuses mainly on the technical aspects, evolving indications, and equipment-related technological advances. Despite the very recent withdrawal of MSE from clinical practice, for completeness, this technology and its technique is still briefly covered here, albeit importantly, along with a short description of reported, associated, serious adverse events which have contributed to its withdrawal/recall from the market and clinical practice.

BACKGROUND: Capsule endoscopy (CE) is the first-choice exploration in case of overt small bowel bleeding (SBB). An early CE is known to increase diagnostic yield, but long reading times may delay therapeutics. The study evaluates the diagnostic performance of the artificial intelligence tool TOP100 in patients with overt SBB undergoing early CE with Pillcam SB3. METHODS: Patients who underwent early CE (up to 14 days from the bleeding episode) for suspected overt SBB were included. One experienced endoscopist prospectively performed standard reading (SR) and a second blind experienced endoscopist performed a TOP100-based reading (TR). The primary endpoint was TR diagnostic accuracy for lesions with high bleeding potential (P2). RESULTS: A total of 111 patients were analyzed. The most common clinical presentation was melena (64%). CE showed angiodysplasias in 40.5% of patients (45/111). In per-patient analysis, TR showed a sensitivity of 90.48% (95% CI 82.09-95.80), specificity of 100% (95% CI 87.23-100) with a PPV of 100% (95% CI 94.01-100), NPV of 77.14% (95% CI 63.58-86.71) and diagnostic accuracy of 92.79 (86.29-96.84). At multivariate analysis, adequate intestinal cleansing was the only independent predictor of concordance between TR and SR (OR 2.909, p = 0.019). The median reading time for SR and TR was 23 min (18.0-26.8) and 1.9 min (range 1.7-2.1), respectively (p < 0.001). CONCLUSIONS: TOP100 provides a fast-reading mode for early CE in case of overt small bowel bleeding. It identifies most patients with active bleeding and angiodysplasias, aiding in the prioritization of therapeutic procedures. However, its accuracy in detecting ulcers, varices and P1 lesions seems insufficient.

MR1: ESGE recommends small-bowel capsule endoscopy as the first-line examination, before consideration of other endoscopic and radiological diagnostic tests for suspected small-bowel bleeding, given the excellent safety profile of capsule endoscopy, its patient tolerability, and its potential to visualize the entire small-bowel mucosa.Strong recommendation, moderate quality evidence. MR2: ESGE recommends small-bowel capsule endoscopy in patients with overt suspected small-bowel bleeding as soon as possible after the bleeding episode, ideally within 48 hours, to maximize the diagnostic and subsequent therapeutic yield.Strong recommendation, high quality evidence. MR3: ESGE does not recommend routine second-look endoscopy prior to small-bowel capsule endoscopy in patients with suspected small-bowel bleeding or iron-deficiency anemia.Strong recommendation, low quality evidence. MR4: ESGE recommends conservative management in those patients with suspected small-bowel bleeding and high quality negative small-bowel capsule endoscopy.Strong recommendation, moderate quality evidence. MR5: ESGE recommends device-assisted enteroscopy to confirm and possibly treat lesions identified by small-bowel capsule endoscopy.Strong recommendation, high quality evidence. MR6: ESGE recommends the performance of small-bowel capsule endoscopy as a first-line examination in patients with iron-deficiency anemia when small bowel evaluation is indicated.Strong recommendation, high quality evidence. MR7: ESGE recommends small-bowel capsule endoscopy in patients with suspected Crohn's disease and negative ileocolonoscopy findings as the initial diagnostic modality for investigating the small bowel, in the absence of obstructive symptoms or known bowel stenosis.Strong recommendation, high quality evidence. MR8: ESGE recommends, in patients with unremarkable or nondiagnostic findings from dedicated small-bowel cross-sectional imaging, small-bowel capsule endoscopy as a subsequent investigation if deemed likely to influence patient management.Strong recommendation, low quality evidence. MR9: ESGE recommends, in patients with established Crohn's disease, the use of a patency capsule before small-bowel capsule endoscopy to decrease the capsule retention rate.Strong recommendation, moderate quality evidence. MR10: ESGE recommends device-assisted enteroscopy (DAE) as an alternative to surgery for foreign bodies retained in the small bowel requiring retrieval in patients without acute intestinal obstruction.Strong recommendation, moderate quality evidence. MR11: ESGE recommends DAE-endoscopic retrograde cholangiopancreatography (DAE-ERCP) as a first-line endoscopic approach to treat pancreaticobiliary diseases in patients with surgically altered anatomy (except for Billroth II patients).Strong recommendation, moderate quality evidence.

BACKGROUND: Motorized Spiral Enteroscopy (MSE) reduces procedure time and increases insertion depth into the small bowel; however, there is scarce evidence on factors affecting MSE efficacy. AIMS: To evaluate diagnostic yield and adverse events of MSE including patients with prior major abdominal surgery. METHODS: A prospective observational study was conducted on patients undergoing MSE from June 2019 to December 2021. Demographic characteristics, procedure time, depth of maximum insertion (DMI), technical success, diagnostic yield, and adverse events were collected. RESULTS: Seventy-four anterograde (54.4%) and 62 retrograde (45.6%) enteroscopies were performed in 117 patients (64 males, median age 67 years). Fifty patients (42.7%) had prior major abdominal surgery. Technical success was 91.9% for anterograde and 90.3% for retrograde route. Diagnostic yield was 71.6% and 61.3%, respectively. The median DMI was 415 cm (264-585) for anterograde and 120 cm (37-225) for retrograde enteroscopy. In patients with prior major abdominal surgery, MSE showed significantly longer small bowel insertion time (38 vs 29 min, p = 0.004), with similar diagnostic yield (61 vs 71.4%, p = 0.201) and DMI (315 vs 204 cm, p = 0.226). The overall adverse event rate was 10.3% (SAE 1.5%), with no differences related to prior abdominal surgery (p = 0.598). Patients with prior surgeries directly involving the gastrointestinal tract showed lower DMI (189 vs 374 cm, p = 0.019) with equal exploration time (37.5 vs 38 min, p = 0.642) compared to those with other abdominal surgeries. CONCLUSIONS: MSE is effective and safe in patients with major abdominal surgery, although longer procedure times were observed. A lower depth of insertion was detected in patients with gastrointestinal surgery.

Stool donors for fecal microbiota transference (FMT) should be rigorously screened to identify any disorder in health status. The success of our screening protocol to identify eligible donors in the last year and a half was evaluated and compared with the published literature. The target population was medical students who responded to 3 public calls to donate stools. Qualified donors brought stool samples to our lab. Out of the 110 students who responded to the call, 26 were enrolled as study donors and delivered at least one stool sample. The main reason for volunteer exclusion was body mass index (BMI) <18.5kg/m2 or >25kg/m2 (n=11) and for the identification of ESBL Escherichia coli in feces (n=3). Our success rate after the screening protocol was considered high. Understanding the incentives to participate is critical to the success of recruitment strategies as FMT is still a little-known practice for general population.

Se debe seleccionar rigurosamente a los donantes de heces para la transferencia de microbiota fecal (TMF) para identificar cualquier trastorno en la salud. Se evaluó el éxito de nuestro protocolo de selección para identificar donantes idóneos en el último año y medio y se comparó con la literatura publicada.La población objetivo fueron estudiantes de medicina que respondieron a 3 convocatorias públicas para donar heces. Los donantes aptos llevaron muestras de heces a nuestro laboratorio.De los 110 estudiantes que respondieron a la convocatoria, 26 se inscribieron como donantes del estudio y entregaron al menos una muestra de heces. El principal motivo para la exclusión de voluntarios fue un índice de masa corporal (IMC) <18,5 kg/m2 o >25 kg/m2 (n=11) y la identificación de E. coli BLEE en las heces (n=3).Nuestra tasa de éxito tras el protocolo de selección se consideró alta. Comprender los incentivos para participar es fundamental para el éxito de las estrategias de reclutamiento, ya que la TMF sigue siendo una práctica poco conocida para la población en general.(AU)

Background and aims: Achieving adequate bowel cleansing is of utmost importance for the efficiency of colon capsule endoscopy (CCE). However, information about predictive factors is lacking. The aim of this study was to assess the predictive factors of poor bowel cleansing in the CCE setting. Methods: In this observational study, 126 patients who underwent CCE at two tertiary care hospitals were included between June 2017 and January 2020. Participants prepared for bowel cleansing with a 1-day clear liquid diet, a 4-L split-dose polyethylene glycol regimen and boosters with sodium phosphate, sodium amidotrizoate and meglumine amidotrizoate. Domperidone tablets and bisacodyl suppositories were administered when needed. Overall and per-segment bowel cleansing was evaluated using a CCE cleansing score. Simple and multiple logistic regression analysis were carried out to assess poor bowel cleansing and excretion rate predictors. Results: Overall bowel cleansing was optimal in 53 patients (50.5%). Optimal per-segment bowel cleansing was achieved as follows: cecum (86 patients; 74.8%), transverse colon (91 patients; 81.3%), distal colon (81 patients; 75%) and rectum (64 patients; 66.7%). In the univariate analysis, elderly (OR, 1.03; 95% CI (1.011.076)) and constipation (OR, 3.82; 95% CI (1.509.71)) were associated with poor bowel cleansing. In the logistic regression analysis, constipation (OR, 3.77; 95% CI (1.4310.0)) was associated with poor bowel cleansing. No variables were significantly associated with the CCE device excretion rate. Conclusion: Our results suggest that constipation is the most powerful predictor of poor bowel cleansing in the CCE setting. Tailored cleansing protocols should be recommended for these patients.(AU)
Antecedentes y objetivos Lograr una limpieza intestinal adecuada es de gran importancia para la eficiencia de la cápsula endoscópica de colon (CEC). Se carece de información sobre factores predictivos. El objetivo fue evaluar los factores predictivos de la limpieza colónica deficiente en pacientes con CEC. Métodos: Ciento veintiséis pacientes fueron sometidos a CEC en dos hospitales de tercer nivel entre junio de 2017 y enero de 2020. La preparación consistió en un día de dieta líquida, y 4 l de polietilenglicol (dosis fraccionada), fosfato sódico, amidotrizoato de sodio y meglumina amidotrizoato. Ocasionalmente se administró domperidona y supositorios de bisacodilo. Se evaluó limpieza total y por segmentos. Se realizó un análisis de regresión logística simple y múltiple para evaluar factores de limpieza deficiente y de excreción de la CEC. Resultados: La limpieza intestinal fue óptima en 53 pacientes (50,5%). Por segmentos fue: ciego y ascendente (86 pacientes; 74,8%), transverso (91 pacientes; 81,3%), distal (81 pacientes; el 75%) y recto (64 pacientes; 66,7%). En la regresión simple, la edad avanzada (OR, 1,03, IC 95% [1,01-1,076]) y el estreñimiento (OR, 3,82; IC 95% [1,50-9,71]) se asociaron con una limpieza deficiente. El estreñimiento (OR, 3,77; IC del 95% [1,43-10,0]) fue el único factor asociado de forma independiente. Ninguna variable se asoció a la tasa de excreción de la CEC. Conclusión: Nuestros resultados sugieren que el estreñimiento es el factor más potente de la limpieza deficiente colónica en el estudio endoscópico con CEC. Protocolos de limpieza adaptados se deben recomendar en estos pacientes.(AU)

(1) Background: Fecal calprotectin (FC) correlates well with colonic inflammatory activity of Crohn's disease (CD); data about relation of FC and small bowel (SB) lesions are still contradictory. The main aim was to analyze the relationship between FC levels and SB inflammatory activity in patients with established or suspected Crohn's disease, assessed by small bowel capsule endoscopy (SBCE) or magnetic resonance enterography (MRE). (2) Methods: Two cohorts of patients were included: 1. Prospective data were collected from patients with established or suspected CD who underwent SBCE and FC (Cohort A); 2. A retrospective cohort of patients who underwent MRE and FC determination (Cohort B). Different cutoffs for FC were tested in both cohorts. (3) Results: 83 patients were included and 66 were finally analyzed. A total of 69.6% had SB lesions seen by SBCE (n = 25) or MRE (n = 21). FC mean levels were 605.74 + 607.07 µg/g (IQ range: 99.00−878.75), being significantly higher in patients with SB lesions compared to patients without lesions (735.91 + 639.70 µg/g (IQ range: 107.75−1366.25) vs. 306.35 + 395.26 µg/g (IQ range: 78.25−411.0), p < 0.005). For cohort A, 25 out of 35 patients had SB lesions and a significant correlation between Lewis Score and FC levels was achieved (R2: 0.34; p = 0.04). FC sensitivity (S), specificity (E), positive predictive value (PPV), and negative predictive values (NPV) for predicting SB lesions were 80%, 50%, 80%, and 50%, respectively, for FC > 100 µg/g. For cohort B, inflammatory SB activity, measured by MaRIA score, was detected in 21 out of 31 patients (67.7%). Patients with positive findings in MRE had significantly higher values of FC than those with no lesions (944.9 + 672.1 µg/g vs. 221 + 212.2 µg/g, p < 0.05). S, E, PPV, and NPV of FC were 89%, 50%, 77.2%, and 71.4% for FC levels > 100 µg/g. The higher sensitivity and specificity of the FC levels for the detection of SB lesions with SBCE and MRE was obtained for an FC cutoff >265 µg/g and >430 µg/g, respectively. (4) Conclusions: FC has a good correlation with the presence of SB lesions, assessed by SBCE and MRE, in patients with established or suspected Crohn's disease. However, the ideal cutoff is here proven to be higher than previously reported. Multicenter and large prospective studies are needed in order to establish definitive FC cutoff levels.
RESUMO
La transferencia de microbiota fecal (TMF) es un tratamiento eficaz y seguro para tratar la infección recurrente por Clostridioides difficile. Es esencial extremar esfuerzos para que la TMF se realice con rigor y en base a los conocimientos científicos. La selección del donante de microbiota fecal es un punto clave del proceso para garantizar la seguridad del receptor. Es necesario disponer de protocolos de actuación que permitan a los clínicos actuar con las máximas garantías y minimizar los riesgos del procedimiento. Por este motivo, en Cataluña se ha constituido un grupo de trabajo multidisciplinario con el objetivo de establecer unas recomendaciones para la selección del donante de microbiota fecal.
Fecal microbiota transplantation (FMT) is an effective and safe treatment to treat recurrent Clostridioides difficile infection. It is essential to make every effort to perform FMT rigorously and based on scientific knowledge. Selection of the fecal microbiota donor is a key point of the process to ensure recipient safety. It is necessary to have protocols of action that allow clinicians to act with the maximum guarantees and to minimize the risks of the procedure. For this reason, a multidisciplinary working group has been set up in Cataluña with the aim of establishing recommendations for the selection of the fecal microbiota donor.
