Core Tip	This study highlights that complications following fine needle biopsy are infrequent and primarily influenced by endoscopist experience rather than the overall burden of comorbidities. Although most patients had at least one comorbidity, no significant association was found between comorbidities and complication rates. Cardiovascular disease emerged as a specific predictor of risk, while arterial hypertension showed a surprising negative association. These findings emphasize the importance of individual clinical factors and endoscopist expertise over cumulative comorbidity scores when assessing procedural risk and ensuring patient safety during fine needle biopsy.
