METHOD OF ENDOSCOPIC TREATMENT OF LUNG ABSCESS Russian patent published in 2020 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to thoracic surgery. Flexible bronchoscope is inserted into the mouth of the segmental bronchus of the lung with a localized abscess. Catheter with a string is passed through the bronchoscope channel in turns through visible subsegmental bronchi with detection of one of them, which allows bringing the distal end of the catheter to the abscess wall at a distance of not more than 1 cm. Catheter is removed with a string from the bronchoscope canal. Biopsy forceps is inserted through the above canal and the revealed subsegment bronchus, the branches of which are opened when approaching the wall of the abscess at a distance of not more than 1 cm. Further, the forceps are further advanced with the branches opened tangentially to the abscess wall at distance of 2 cm to form 5 mm-wide tunnel in the lung tissues. Biopsy tongs are withdrawn. Draining catheter is introduced into the tunnel with further introduction of a contrast agent into the catheter. Antibacterial and / or antiseptic solutions are introduced 5 to 8 times a day in an increasing volume providing hydraulic pressure to tunnel walls, but not more than 15 ml. First introduction of the antibacterial or antiseptic solution into the draining catheter is performed in a volume exceeding the catheter volume by 1–2 ml. Solutions are introduced for 5–14 days before a full obliteration of a purulent cavity.

EFFECT: method enables endoscopic treatment of lung abscess, which can not be drained by conventional methods by transbronchial approach due to a thick, dense wall of the cavity or due to obstruction of the draining bronchus, deformation and displacement of small bronchi by an abscess, as well as reduce the risk of complications such as hemoptysis, pneumothorax and phlegmon of the breast wall.
