| Abstract (English): |
Objective: The aim of this study was to analyze the reliability of agreement between surgeons when using the Parkland Grading Scale for Acute Cholecystitis (PGS-AC). Methods: A total of 43 images taken out of videos of laparoscopic cholecystectomies (LCs) were collected, they were used to frame an online questionnaire that was sent to 18 surgeons and resident doctors who classified the images according to the Parkland scale criteria, followed by the evaluation of concordance between observers applying the Fleiss κ test. Results: A global Fleiss κ value of 0.213 was obtained, which corresponds to a low interobserver concordance. Factors such as being a surgical resident, having more than 10 years of experience performing this type of procedure, or performing more than 2 LCs per week, were related to greater concordance in diagnosis. Conclusions: The low concordance found when using the Parkland grading scale, translates into a high interobserver variation related to multiple variables, which is why, we are not seeing the same.

Objetivo: Analizar la fiabilidad de la concordancia entre cirujanos al utilizar la PGS-AC (Parkland Grading Scale for Acute Cholecystitis). Métodos: Se recolectaron 43 imágenes extraídas de vídeos de colecistectomías laparoscópicas y se realizó un cuestionario en línea que se envió a 18 cirujanos y médicos residentes, quienes clasificaron las imágenes según los criterios de la PGS-AC. Se evaluó la concordancia entre observadores aplicando la prueba kappa de Fleiss. Resultados: Se obtuvo un valor kappa de Fleiss global de 0.213, lo que corresponde a una baja concordancia interobservador. Factores como ser residente de cirugía, tener más de 10 años de experiencia realizando este tipo de procedimientos o realizar más de dos colecistectomías laparoscópicas por semana se relacionaron con una mayor concordancia en el diagnóstico. Conclusiones: La baja concordancia encontrada al utilizar la PGS-AC se traduce en una alta variación interobservador relacionada con múltiples variables, por lo que no estamos viendo lo mismo.
