The possibilities of using physiotherapy for the treatment of the children with destructive appendicitis and its complications in the postoperative period are discussed. The effects of various physical factors applied with due regard for the severity of the disease are analysed based on the comparison of the results of laboratory and functional investigations in conjunction with the estimation of dynamics of clinical conditions. Special emphasis is laid on the application of electrostimulation, microwave therapy, magnetotherapy, and laserotherapy for the postoperative rehabilitative treatment. It was shown that normalization of the majority of the studied parameters was achieved by the end of the combined physiotherapeutic treatment in 86.6% of the patients compared with 39% in the control group that were treated without the application of the physical factors. It is concluded that the use of physiotherapeutic methods in the early rehabilitative period after destructive appendicitis promotes the recovery of the motor-evacuatory function of the intestines and relieves the inflammatory processes in the abdominal cavity.
