Clinical examination of 34 patients showed that lymphotropic administration of antibiotics creates concentrations in organs and tissues involved in the inflammatory process in acute cholecystitis which are 1.63-14.95 times higher than those produced by intramuscular injection. Study of the course of the clinical picture of the disease in 122 patients with acute destructive cholecystitis revealed the high efficacy of this method of antibiotic therapy: the laboratory indices of the inflammation became normal within a shorter period of time, the inflammatory process in the gallbladder was arrested more rapidly, the number of postoperative complications fell 2.6 times, and the terms of hospital-stay of the patients reduced by 1.3 times. Lymphotropic antibiotic therapy is more pathogenetic in the management of acute destructive cholecystitis.
