Summary: | Graft-versus-host disease (GvHD) is a complication of hematopoietic cell transplantation, and the small bowel is one of the main targets in the gastrointestinal tract. Capsule endoscopy is a safe procedure and can be useful in the diagnosis of GvHD. The aim of the present study was to compare the diagnostic yield of capsule endoscopy with the histopathologic findings in GvHD.
A retrospective diagnostic test study included all the patients with suspected GvHD that underwent gastroscopy and colonoscopy, with histopathologic evaluation of the biopsies taken, and capsule endoscopy, within the time frame of July 2015 and July 2019. Capsule endoscopy findings were compared with the histopathologic diagnosis, considered the gold standard.
Twenty-one patients with GvHD (7 [33%] women; 37 ± 11.9 years of age) were included, 20 (95%) of whom had acute GvHD. The median gastric transit time of the capsule was 55 minutes (20-113) and the median small bowel transit time was 261 minutes (238-434). The entire small bowel was visualized through capsule endoscopy in 17 cases (80.95%). The histopathologic findings and capsule endoscopy findings resulted in the diagnosis of GvHD in 17 and 16 cases, respectively. There was agreement between the histopathologic and capsule endoscopy findings in 18 cases (15 positive and 3 negative). Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic yield of capsule endoscopy were 88%, 75%, 94%, 60%, and 85%, respectively.
Capsule endoscopy is a safe tool for the diagnosis of GvHD, with high sensitivity and positive predictive value, as well as moderate agreement with histopathologic findings.
La enfermedad injerto contra huésped (EICH) es una complicación del trasplante de células hematopoyéticas. El intestino delgado (ID) es una área afectada del TD. La cápsula endoscópica (CE) es un procedimiento seguro y puede ser útil en el diagnóstico de EICH. El objetivo del trabajo es comparar el rendimiento diagnóstico de la CE con los hallazgos histopatológicos en EICH.
Estudio de prueba diagnóstica retrospectivo que incluyó a todos los pacientes con sospecha EICH con estudio histopatológico de biopsias por gastroscopia y colonoscopia y CE, entre julio 2015 y julio 2019. Los hallazgos de CE fueron comparados con el diagnóstico histopatológico como prueba de oro.
Se incluyeron a 21 pacientes con EICH [7 (33%) mujeres; 37 (± 11.9) años]. 20 (95%) tenían EICH agudo. La mediana del tiempo de tránsito gástrico fue de 55 minutos (20-113) y la del tiempo de tránsito del ID de 261 minutos (238-434). La visualización completa del ID por CE se observó en 17 casos (80.95%). Los hallazgos histopatológicos y de CE diagnosticaron EICH en 17 y 16 casos, respectivamente. El acuerdo entre hallazgos histopatológicos y de CE se identificó en 18 casos (15 positivos y 3 negativos). La sensibilidad, especificidad, valor predictivo positivo (VPP), valor predictivo negativo y rendimiento diagnóstico de la CE fue de 88%, 75%, 94%, 60% y 85%, respectivamente.
La CE es una herramienta segura para el diagnóstico de EICH con alta sensibilidad y VPP, y concordancia moderada con los hallazgos histopatológicos. |
