Complication of transesophageal fine-needle aspiration of the mediastinal lymph nodes. Clinical observation

Ultrasound-guided fine-needle aspiration is an invasive intervention which is used for diagnosis of additional formations of the walls of the gastrointestinal tract, as well as focal pathologies beyond it. Many reports indicate high diagnostic effectiveness and safety of this method but with increasing number of aspirations endoscopists start to encounter rare complications of this manipulation. The article presents a description of a rare complication which arose during transesophageal fine-needle aspiration, as well as a correct algorithm of patient management in the post-manipulation period. Determination of the correct strategy of patient management led to favorable outcome of the complication and determination of the final clinical diagnosis.
