Taking into account a high rate of unsatisfactory results of surgical treatment of chronic anal fissures (CAF), low quality of life and the need for postoperative (p/o) rehabilitation of such patients, the objective of the work was to improve the results of surgical treatment of CAF due to optimization of the early p/o period. We examined 68 patients with the CAF. In the main group during the p/o period since the 2nd day, the intratissue electrophoresis was performed from 3 to 5 times with «Dioxysol®-Darnitsa» solution with a current density of 0.05 mA/cm2, during 60 minutes, in the control group - standard methods of p/o treatment were used. The intensity of pain was significantly reduced from the third day after the operation in patients who had galvanization sessions since the 2nd day, as well as during the entire period of the early period, the pain level was always significantly lower than in the control group. If on the first day after the operation all patients needed anesthesia, and the majority of them received narcotic analgesics, on the third day only 4 (11.43%) of the patients in the main group received anesthesia contrary to all patients (100%) of the control group. On the fourth day, the main group did not require anesthesia, while in the control group 28 patients (84.85%) still had anesthesia. Assessing the p/o period and remote results of treatment, according to all criteria, the effectiveness of treatment tactics in the main group is higher. In particular, the relapse of fissures occurred in 2.32 times more often in the control group. In addition, it became possible to reduce the time of complete wound healing by 2.66 days. The use of intra-tissue electrophoresis in patients at the early p/o period after surgical treatment of CAF increases the effectiveness of treatment by 31%, improves the quality of life of patients by 1,2-1,3 times, promotes rapid recovery after surgery, reduces the frequency of early and late p/o complications.
