The course of the treatment process with Lucilia sericata larvae in the biobag in case no. 2. (A) Wound after scraping before larvae application: visible healing inhibition, locally dense hard fibrin without the possibility of thorough debridement using mechanical and surgical methods. (B) Second day of MDT in the biobag—3 bags with 100 pcs. (C) Third day of the MDT—visible signs of capillary bleeding, which prompted the completion of the wound debridement process with this method. (D) State of the wound after 7 days: slight granulation process, moderate exudate, moderate amount of fibrin, easy for scraping, pain only during debridement, change of dressings (TLC-NOSF polyacrylate + antiseptic gel every 3 days plus scraping). (E) Condition of the wound after 14 days: weak granulation process visible, scarce exudate. (F) Condition of the wound after 21 days: no pain, more and more clumps of granulation tissue, healing process unsatisfactory.
