ABSTRACT

Background: Histological diagnosis of pulmonary nodules requires surgical resection on many occasions. There are multiple localization strategies each with their own benefits and complications. The objective of this study is to compare preoperative lung nodule localization with hookwire and radiotracer injection (radioguided occult lesion localization, ROLL). To compare results, complications, and volume of the sample resected with both techniques. Methods: Patients undergoing resection of pulmonary nodules with video-assisted thoracoscopy and pre-surgical localization with hookwire or ROLL were studied. Eighty-eight pulmonary nodules were resected in 76 patients: 52 with a hook wire and 36 with a radiotracer. The localization rate, the shortest distance between the nodule and the pleura, the intrapulmonary distance of the locator, the complications, the volume of the resection piece, and the histological result were all assessed. In addition, the factors that influence the volume of the surgical piece were analyzed. Results: All the nodules were resected with both techniques. The intrapulmonary path of the locator is longer for the ROLL group (23.91 vs. 16.28 mm; P=0.04), with no differences in the distance from the nodule to the pleura. The rate of pneumothorax was significantly higher after the placement of a hook wire (69.2% vs. 24.2%; P<0.0001), while there were no differences in the presence of hemorrhage. The volume of the pieces resected using ROLL was more minor than with hookwire, although not statistically significant (20.19 vs. 34.26 cc; P=0.07). Conclusions: Preoperative localization with the ROLL technique is safer than the placement of hookwire. In addition, the ROLL technique shows a tendency to obtain a smaller volume of resected tissue since the marking is not affected by the intrapulmonary route used during marker placement. ROLL technique allows to locate lung nodules with fewer complications than hookwire and probably gets smaller resection samples.

ABSTRACT

OBJETIVO: Describir las medidas adoptadas dentro del plan de contingencia del COVID-19 respecto a la biopsia selectiva de ganglio centinela (BSGC) y analizar su impacto sobre la actividad asistencial. METODOLOGÍA: Estudio cualitativo, descriptivo y retrospectivo de BSGC realizadas durante el período del 14/03 al 11/05 de 2020. Análisis de las medidas tomadas para minimizar las probabilidades de contagio y resultados de PCR de pacientes y personal. Comparativa de casos con los realizados en el mismo período de 2019. Actividad diaria de linfogammagrafía y de cirugía radioguiada (CRG) por indicación médica. Cálculo numérico y porcentual de CRG por hospital y recursos humanos diarios de medicina nuclear requeridos. RESULTADOS: Se realizaron 42 intervenciones con BSGC, un 31,1% menos que en 2019. La indicación médica de cáncer de mama experimentó el mayor descenso de actividad (n=18, 41,9%). Del total de CRG, Hospital Clínic realizó el 45,2%, Hospital Maternitat el 31,0%, Hospital Plató el 16,7% y Hospital Sant Joan de Déu el 7,1% restante. En relación con los recursos humanos, la planificación inicial se cumplió en un 77% de los días. El total de los controles PCR a pacientes (n=42) y personal de CRG (n=9) dio resultado negativo. CONCLUSIONES: El COVID-19 influyó negativamente en la actividad asistencial de la BSGC del Hospital Clínic, pero fue compensado por una planificación acertada, basada en el análisis previo de los procesos del procedimiento, que permitió adaptar los recursos de material y personal a las circunstancias cambiantes, otorgándole una flexibilidad que posibilitó el cumplimiento de la programación establecida


OBJECTIVE: To describe the measures taken within the COVID-19 contingency plan concerning sentinel lymph node biopsy (SNB) procedures and to assess their impact on healthcare activity. METHODOLOGY: Qualitative, descriptive and retrospective study of SNB procedures conducted during the lockdown period of COVID-19 (14/03 to 11/05 2020). Analysis of measures taken to minimise the chances of contagion and PCR outcomes of patients and staff. Comparison with SNB procedures conducted in the same time interval in 2019. Daily activity of lymphoscintigraphy and radioguided surgery (RGS) by medical indication. Numerical and percentage calculation of RGS by hospital and daily requirements for human resources in nuclear medicine. RESULTS: Forty-two SNB were performed, representing 31.1% less than those conducted in the same period in 2019. The medical indication of breast cancer showed the greatest activity decrease (n=18, 41.9%). RGS was performed in 45.2% of patients in Hospital Clínic, 31.0% in Maternitat, 16.7% in Plató and 7.1% in Sant Joan de Déu Hospital. Concerning the human resources required, the initial planning was accomplished in 77% of the days (24/31). All the PCR samples from patients (n=42) and RGS staff (n=9) were negative for COVID-19. CONCLUSIONS: COVID-19 negatively influenced the healthcare activity of SNB in Hospital Clínic, but was compensated by adequate planning, based on prior analysis of the procedure's processes, which allowed adaptation of material and personnel resources to the changing circumstances. This allowed flexibility, which in turn enabled compliance with the established schedule
