BackgroundGastrointestinal complications after lung transplatation are associated with an increased risk of morbidity and mortality. This study aims to describe severe gastrointestinal complications (SGC) after lung transplantation.MethodsWe performed a prospective, observational study that included 136 lung transplant patients during a seven year period in a tertiary care universitary hospital. SGC were defined as any diagnosis related to the gastrointestinal or biliary tract leading to lower survival rates or an invasive therapeutic procedure. Early and late complications were defined as those occurring < 30 days and ≥ 30 days post-transplant. The survival function was calculated through the Kaplan-Meier estimator. Variables were analyzed using univariate and multivariate analysis. Statistical significance was defined as p < 0.05.ResultsThere were 17 (12.5%) SGC in 17 patients. Five were defined as early. Twelve patients (70.6%) required surgical treatment. Mortality was 52.9% (n = 9). Patients with SGC had a lower overall survival rate compared to those who did not (14 vs 28 months, p = 0.0099). The development of arrhythmias in the first 48 h of transplantation was a risk factor for gastrointestinal complications (p = 0.0326).ConclusionsSGC are common after lung transplantation and are associated with a considerable increase in morbidity-mortality. Early recognition is necessary to avoid delays in treatment, since a clear predictor has not been found in order to forecast this relevant comorbidity.

La incidencia de neumomediastino en los pacientes hospitalizados con diagnóstico de neumonía por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2) no es para nada desdeñable, muy superior en comparación con la población general. La fisiopatología del neumomediastino en la neumonía por SARS-CoV-2 viene explicada por el aumento del gradiente de presión alveolo-intersticio (accesos de tos seca, trabajo respiratorio, barotrauma por soporte ventilatorio) sobre unos pulmones especialmente «frágiles» debido al daño alveolo-intersticial difuso de origen infeccioso-inflamatorio, todo lo cual aumenta significativamente el riesgo de rotura de la pared alveolar. Cuanta mayor gravedad revista la neumonía por SARS-CoV-2, más probable será la aparición de neumomediastino. El desarrollo de neumomediastino en pacientes con neumonía por SARS-CoV-2 se asocia a unas frecuencias mayores de exitus letalis, ingreso en unidad de cuidados intensivos (UCI) y traqueostomía y a unos tiempos mayores de estancia hospitalaria y en UCI. En la mayoría de los casos, el neumomediastino producido en el seno de la neumonía por SARS-CoV-2 es un proceso benigno y autolimitado que se resuelve con tratamiento conservador.
