BACKGROUND: Despite progress in treating pulmonary echinococcosis (PE), the choice of surgical intervention for complicated and giant cysts remains controversial. Key issues include lung lesion assessment, determining optimal surgical tactics for ruptured echinococcal cysts in the bronchus or pleural cavity, treatment strategies, and analyzing early and late postoperative complications and patient quality of life.
METHODS: microbial contamination. Comparative healing process studies were conducted on lung lobe resections with and without the use of a composite hemostatic coating, “HEMOBEN,” and laser stimulation. The findings will help develop a new resection method for complicated echinococcal lung lesions (EL). Experiments were conducted at the State Institution “RSSPMCS” between 2021 and 2022.During lung resection (lobectomy) in rats, a small amount of air leaked through the lung puncture sites, even with atraumatic 4/0 needles and U-shaped sutures. In the control group, postoperative hypoxia was observed, which led to delayed physical recovery. Blood accumulation in the right pleural cavity and partial lung collapse occurred, with healing delayed by 14 to 21 days.
RESULTS: In the experimental group, breathing resumed immediately after surgery due to hemo- and aerostasis from the application of HEMOBEN. Laser stimulation accelerated wound healing without infection. At euthanasia, lungs were fully expanded, and no effusion or hematoma was detected in the pleural cavity.
CONCLUSIONS: A new method for treating giant infected echinococcal lung cysts is proposed for thoracic surgery. This approach involves anatomical lung resection, manual bronchial stump suturing, followed by local laser exposure and the application of Chemoben powder on the lung and bronchial stump wound surfaces.
