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.
