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)

Enfermedades inflamatorias mediadas por inmunidad en pacientes con enfermedad inflamatoria intestinal. Datos basales del estudio Aquiles / Immune-mediated inflammatory diseases in patients with inflammatory bowel disease. Baseline data from the Aquiles study

OBJETIVO: Determinar la prevalencia de enfermedades inflamatorias mediadas por inmunidad (EIMI) en una cohorte de pacientes con enfermedad inflamatoria intestinal (EII) reclutada en consultas hospitalarias de aparato digestivo para el estudio Aquiles, un estudio prospectivo de 2 años de seguimiento. Material y métodos Se incluyeron pacientes de ≥ 18 años con diagnóstico previo o nuevo de EII (enfermedad de Crohn [EC], colitis ulcerosa [CU] o colitis indeterminada). Los diagnósticos se recogieron de forma transversal de la historia clínica en el momento de incorporar a cada paciente al estudio. Resultados Se incluyeron 526 pacientes (edad media 40,2 años; 47,3% hombres, 52,7% mujeres), 300 con EC (57,0%), 218 con CU (41,4%) y 8 colitis indeterminada. Presentaron otra EIMI 71 pacientes (prevalencia: 13,5%, IC 95%: 10,8-16,7): 47 fueron espondiloartritis (prevalencia: 8,9%); 18 psoriasis (3,4%); 5 pioderma gangrenoso (1,0%) y 11 uveítis (2,1%). La prevalencia de EIMI fue mayor en pacientes con EC respecto a pacientes con CU (17,0% [IC 95%: 13,2-21,7] frente a 9,2% [IC 95%: 6,0-13,8], p = 0,011). En el análisis multivariante, las variables asociadas a la presencia de EIMI fueron el diagnóstico de EC (OR = 1,8 [IC 95%: 1,1-3,2]) y un tiempo de evolución de la EII ≥ 4 años (OR = 2,1 [IC 95%: 1,1-4,1] en aquellos con 4-8 años, y OR = 2,1 [IC 95%: 1,2-3,9] en los de ≥ 8 años frente a < 4 años). CONCLUSIONES: En la cohorte de pacientes con EII del estudio Aquiles, el 13,5% presentó otra EIMI, con una prevalencia mayor en pacientes con EC y > 4 años de evolución de la enfermedad

OBJECTIVE: To determine the prevalence of immune-mediated inflammatory diseases (IMID) in a cohort of patients with inflammatory bowel disease(IBD) enrolled in hospital gastroenterology outpatients units for the AQUILES study, a prospective 2-year follow-up study. MATERIAL AND METHODS: We included patients ≥18 years old with a prior or new diagnosis of IBD (Crohn disease [CD], ulcerative colitis [UC] or indeterminate colitis). Diagnoses were collected in a cross-sectional manner from the clinical records at enrollment of a new patient in the study. RESULTS: We included 526 patients (mean age 40.2 years; 47.3% men, 52.7% women), 300 with CD (57.0%), 218 with UC (41.4%) and 8 with indeterminate colitis. Other types of IMID were present in 71 patients (prevalence: 13.5%, 95% CI: 10.8-16.7): 47 were spondyloarthropathies (prevalence: 8.9%); 18 psoriasis (3.4%); 5 pyoderma gangrenosum (1.0%), and 11 uveitis (2.1%). The prevalence of IMID was higher in patients with CD than in those with UC (17.0% [95% CI: 13.2-21.7] vs 9.2% [95% CI: 6.0-13.8], p=0.011). In the multivariate analysis, the variables associated with the presence of IMID were diagnosis of CD (OR=1.8 [95% CI: 1.1-3.2]) and duration of IBD ≥4 years (OR=2.1 [95% CI: 1.1-4.1] in those with disease duration 4-8 years, and OR=2.1 [95% CI: 1.2-3.9] in those with ≥8 years vs. <4 years).CONCLUSIONS: In the cohort of patients with IBD in the AQUILES study, 13.5% had another IMID, with a higher prevalence in patients with CD and>4 years since disease onset (AU)

Capsule endoscopy capture rate: has 4 frames-per-second any impact over 2 frames-per-second?

AIM: To compare the current capsule and a new prototype at 2 and 4 frames-per-second, respectively, in terms of clinical and therapeutic impact. METHODS: One hundred patients with an indication for capsule endoscopy were included in the study. All procedures were performed with the new device (SB24). After an exhaustive evaluation of the SB24 videos, they were then converted to "SB2-like" videos for their evaluation. Findings, frames per finding, and clinical and therapeutic impact derived from video visualization were analyzed. Kappa index for interobserver agreement and χ (2) and Student's t tests for qualitative/quantitative variables, respectively, were used. Values of P under 0.05 were considered statistically significant. RESULTS: Eighty-nine out of 100 cases included in the study were ultimately included in the analysis. The SB24 videos detected the anatomical landmarks (Z-line and duodenal papilla) and lesions in more patients than the "SB2-like" videos. On the other hand, the SB24 videos detected more frames per landmark/lesion than the "SB2-like" videos. However, these differences were not statistically significant (P > 0.05). Both clinical and therapeutic impacts were similar between SB24 and "SB2-like" videos (K = 0.954). The time spent by readers was significantly higher for SB24 videos visualization (P < 0.05) than for "SB2-like" videos when all images captured by the capsule were considered. However, these differences become non-significant if we only take into account small bowel images (P > 0.05). CONCLUSION: More frames-per-second detect more landmarks, lesions, and frames per landmark/lesion, but is time consuming and has a very low impact on clinical and therapeutic management.

[Gastric polyposis due to treatment with proton pump inhibitors]. / Poliposis gástrica secundaria a tratamiento con inhibidores de la bomba de protones.

Fundic gland polyps can appear sporadically or in association with familial adenomatous polyposis syndrome. An association between fundic gland polyps and prolonged treatment with proton pump inhibitors has been described, as has their regression after withdrawal of these inhibitors. Dysplastic components are not usually associated. We describe four patients who were receiving chronic treatment with proton pump inhibitors. The results of prior endoscopic analysis were normal. The presence of multiple fundic gland polyps was detected as was their disappearance 6 months after treatment cessation.
