A comprehensive examination of small-bowel capsule endoscopy in Spanish centers to meet European Society of Gastrointestinal Endoscopy standards.

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.

Oral ingestion versus endoscopic delivery of endoscopic capsule in patients with previous gastrointestinal surgery (ORENCES study): A Spanish multicentre observational study / Ingesta oral versus colocación endoscópica de la cápsula endoscópica en pacientes con cirugía gastrointestinal previa (estudio ORENCES): un estudio observacional multicéntrico español

Background: Small Bowel Capsule Endoscopy is the first-choice technique for investigating the majority of small bowel diseases. Its most common complications are related to incomplete examinations and capsule retention. There is no consensus on how patients with previous gastrointestinal surgery should receive the capsule. Objective: The primary endpoint was to compare the rate of complete small-bowel examinations (completion rate) between oral ingestion and endoscopic delivery of the capsule. The secondary endpoint was to compare diagnostic yield and adverse events in the two groups. Methods: A retrospective observational study was conducted in nine hospitals in Spain. Demographic data, previous surgery, indication for capsule endoscopy, intestinal transit time, diagnosis, completion rate (percentage of capsules reaching the caecum), diagnostic yield (percentage of results compatible with indication for the exam) and adverse events were collected. Results: From January 2009 to May 2019 fifty-seven patients were included (39 male, mean age 66±15 years). The most common indications for the exam were “overt” (50.9%) and “occult” (35.1%) small bowel bleeding. Previous Billroth II gastrectomy and Roux-en-Y gastric bypass were present in 52.6% and 17.5% of patients respectively. The capsule was swallowed in 34 patients and placed endoscopically in 23 patients. No significant differences were observed between the oral ingestion and endoscopic delivery groups in terms of completion rate (82.4% vs. 78.3%; p=0.742), diagnostic yield (41.2% vs. 52.2%; p=0.432) or small bowel transit time (301 vs. 377min, p=0.118). No capsule retention occurred. Only one severe adverse event (anastomotic perforation) was observed in the endoscopic delivery group. Conclusions: In our case series, there were no significant differences between oral ingestion and endoscopic delivery in terms of completion rate, diagnostic yield or safety.(AU)

Antecedentes: La cápsula endoscópica representa la técnica de primera elección para investigar la mayoría de las enfermedades del intestino delgado. Sus complicaciones más comunes frecuentes son las exploraciones incompletas y la retención a nivel de intestino delgado. Hasta el momento no hay acuerdo sobre cómo administrar la cápsula a los pacientes que han sido sometidos a una cirugía gastrointestinal previa. Objetivo: El objetivo principal fue comparar la tasa de estudios completos entre la ingestión oral y la administración endoscópica de la cápsula. Los objetivos secundarios fueron comparar el rendimiento diagnóstico y los eventos adversos en ambos grupos. Métodos: Se realizó un estudio observacional retrospectivo en 9 hospitales de España. Se recogieron datos demográficos, cirugía previa, indicación de cápsula endoscópica, tiempo de tránsito intestinal, diagnóstico, tasa de estudios completos (porcentaje de cápsulas que llegan al ciego), rendimiento diagnóstico (porcentaje de resultados compatibles con la indicación del examen) y eventos adversos. Resultados: Desde enero de 2009 hasta mayo de 2019 se incluyeron 57 pacientes (39 hombres, edad media 66 ± 15 años). Las indicaciones más frecuentes para el examen fueron hemorragia de intestino delgado «manifiesta» (50,9%) y «oculta» (35,1%). El 52,6% de los pacientes presentaba gastrectomía Billroth II y el 17,5% bypass gástrico en Y de Roux. La cápsula fue ingerida en 34 pacientes y colocada endoscópicamente en 23 pacientes. No se observaron diferencias significativas entre los grupos de ingesta oral y de colocación endoscópica en cuanto a tasa de estudios completos (82,4% vs. 78,3%; p = 0,742), rendimiento diagnóstico (41,2% vs. 52,2%; p = 0,432) y tiempo de tránsito del intestino delgado (301 vs. 377 min, p = 0,118). No hubo casos de cápsulas retenidas. Solo se observó un evento adverso severo (perforación anastomótica) en el grupo de colocación endoscópica...(AU)

Metastasis of dermatofibrosarcoma diagnosed by capsule endoscopy.

In the study of obscure gastrointestinal bleeding, which includes iron-deficiency anemia, the capsule endoscopy is a valuable diagnostic tool. In the different series the presence of tumors reaches 16% as the cause of it. We present the case of a rare tumor with metastatic extension in the small intestine in which the capsule endoscopy was key to the diagnosis and survival of the patient.

Role of capsule endoscopy in alarm features and non-responsive celiac disease: A European multicenter study.

BACKGROUND AND AIM: The role of capsule endoscopy (CE) in established celiac disease (CD) remains unclear. Our objective was to analyze the usefulness of CE in the suspicion of complicated CD. METHODS: This was a retrospective multicenter study. One hundred and eighty-nine celiac patients (mean age: 46.6 ± 16.6, 30.2% males) who underwent CE for alarm symptoms (n = 86, 45.5%) or non-responsive CD (n = 103, 54.5%) were included. Diagnostic yield (DY), therapeutic impact and safety were analyzed. RESULTS: Capsule endoscopy was completed in 95.2% of patients (small bowel transit time: 270.5 ± 100.2 min). Global DY was 67.2%, detecting atrophic mucosa (n = 92, 48.7%), ulcerative jejunoileitis (n = 21, 11.1%), intestinal lymphoma (n = 7, 3.7%) and other enteropathies (n = 7, 3.7%, six Crohn's disease cases and one neuroendocrine tumor). The DY of CE was significantly higher in patients presenting with non-responsive disease compared to patients with alarm symptoms (73.8% vs 59.3%, P = 0.035). The new findings of the CE modified management in 59.3% of the cases. There were no major complications. CONCLUSION: Capsule endoscopy may be a moderately helpful and safe diagnostic tool in the suspicion of complicated CD, modifying the clinical course of these patients.

Therapeutic impact of colon capsule endoscopy with PillCam(TM) COLON 2 after incomplete standard colonoscopy: a Spanish multicenter study

Introduction: Colon capsule endoscopy (CCE) is an alternative approach for the examination of the colon in patients who refuse colonoscopy or after incomplete colonoscopy (IC). We conducted a study to determine the frequency of complete colonoscopy after IC, the diagnostic yield of CCE, the therapeutic impact of lesions found in CCE, the level of colon cleanliness and the safety of the procedure. Methods: We performed a prospective, multicenter study involving ten Spanish hospitals. Consecutive outpatients aged ≥ 18 years with previous IC were invited to participate. The latest version of the CCE device, PillCam(TM) COLON 2 (CCE-2), was administered to all patients according to the protocol. Results: The study population comprised 96 patients. The most frequent cause of IC was the inability to move past a loop using standard maneuvers (75/96 patients, 78%). Complete visualization of the colon was obtained with CCE-2 in 69 patients (71.9%). Of the 27 patients in whom the CCE-2 did not reach the hemorrhoidal plexus, it passed the colonic segment explored with the previous colonoscopy in 20 cases; therefore, it could be inferred that a combined approach (CCE-2 plus colonoscopy) enabled complete visualization of the colonic mucosa in 92.7% of patients. CCE-2 revealed new lesions in 58 patients (60.4%). Polyps were the most frequent finding (41 patients; 42.7% of the total number of patients). In 43 of the 58 patients (44.8% of the total number of patients), the new lesions observed led to modification of therapy, which included a new colonoscopy for polyp resection or surgery in patients with colonic neoplasm. Conclusions: CCE-2 is a suitable diagnostic procedure that can lead to more frequent diagnosis of significant colonic lesions after IC (AU)

Role of capsule endoscopy in suspected celiac disease: A European multi-centre study.

AIM: To analyze the diagnostic yield (DY), therapeutic impact (TI) and safety of capsule endoscopy (CE). METHODS: This is a multi-centre, observational, analytical, retrospective study. A total of 163 patients with suspicion of celiac disease (CD) (mean age = 46.4 ± 17.3 years, 68.1% women) who underwent CE from 2003 to 2015 were included. Patients were divided into four groups: seronegative CD with atrophy (Group-I, n = 19), seropositive CD without atrophy (Group-II, n = 39), contraindication to gastroscopy (Group-III, n = 6), seronegative CD without atrophy, but with a compatible context (Group-IV, n = 99). DY, TI and the safety of CE were analysed. RESULTS: The overall DY was 54% and the final diagnosis was villous atrophy (n = 65, 39.9%), complicated CD (n = 12, 7.4%) and other enteropathies (n = 11, 6.8%; 8 Crohn's). DY for groups I to IV was 73.7%, 69.2%, 50% and 44.4%, respectively. Atrophy was located in duodenum in 24 cases (36.9%), diffuse in 19 (29.2%), jejunal in 11 (16.9%), and patchy in 10 cases (15.4%). Factors associated with a greater DY were positive serology (68.3% vs 49.2%, P = 0.034) and older age (P = 0.008). On the other hand, neither sex nor clinical presentation, family background, positive histology or HLA status were associated with DY. CE results changed the therapeutic approach in 71.8% of the cases. Atrophy was associated with a greater TI (92.3% vs 45.3%, P < 0.001) and 81.9% of the patients responded to diet. There was one case of capsule retention (0.6%). Agreement between CE findings and subsequent histology was 100% for diagnosing normal/other conditions, 70% for suspected CD and 50% for complicated CD. CONCLUSION: CE has a high DY in cases of suspicion of CD and it leads to changes in the clinical course of the disease. CE is safe procedure with a high degree of concordance with histology and it helps in the differential diagnosis of CD.

Diagnóstico atípico mediante cápsula endoscópica: enfermedad de Whipple / Atypical diagnosis diagnosis by endoscopic capsule: Whipple´s disease

La enfermedad de Whipple es una infección sistémica crónica producida por el actinomiceto Tropheryma whipplei. Las pruebas endoscópicas son claves en el diagnóstico ya que permiten la toma de biopsia y su estudio anatomopatológico para el diagnóstico definitivo de esta entidad. Presentamos un caso de enfermedad de Whipple en el que la cápsula endoscópica, poco común para el diagnóstico de esta afección, fue clave para el mismo y su realización antes y después del tratamiento antibiótico permite describir la evolución macroscópica de los hallazgos en intestino delgado. Este caso ilustra la utilidad de la cápsula endoscópica al permitir un estudio completo del intestino delgado en esta enfermedad en la que hasta el 30% de los pacientes puede cursar con gastroscopia normal (AU)

Whipple´s disease is a chronic systemic infection produced by the actinomycete Tropheryma whipplei. Endoscopic tests are key in the diagnosis as they allow biopsy and histopathological examination for definitive diagnosis of this entity. We present a case of Whipple´s disease where capsule endoscopy, uncommon for the diagnosis of this condition, was essential for it and its performance before and after antibiotic treatment allows to describe the macroscopic evolution of the findings in the small bowel. This case illustrates the utility of capsule endoscopy to allow complete examination of the small bowel disease in which up to 30% of patients may present with normal endoscopy (AU)
