Abstract

Strengthening of the lower uterine segment and formation of a “closing apparatus” for carrying a subsequent pregnancy in the absence of the cervix in patients with cervical cancer after conserving treatment in the amount of radical transabdominal trachelectomy. Materials and Research Methods: the study included 26 patients with cervical cancer of stage I in the reproductive age who received treatment in the amount of radical transabdominal trachelectomy (RTT). In the course of surgery in the amount of RTT, after an imposition of an utero-vaginal anastomosis, the strengthening of the lower uterine segment by setting and fixing a mesh of TiNi and its modelling within the range from the lower uterine segment to the upper third of the vagina was performed. Results: with regard to the issue of strengthening the utero-vaginal anastomosis, the implant takes over the function of the basic "closing apparatus" of the uterine and provides functional support and stability of the utero-vaginal anastomosis against the effects of intrauterine and intraperitoneal pressure. Conclusion: the usefulness of a mesh implant of the superelastic TiNi is due to its biomechanical properties: it is not absorbed, but gets fused with the surrounding tissue and provides resistance of tissues to excessive strain.
