Унилатеральная гибридная хирургическая реконструкция тазового дна. Модифицированная лоскутная методика

Abstract

Sacrospinous fixation is one of the most studied treatments for pelvic organ prolapse (POP), but the prevention of implantrelated complications remains unresolved. To isolate the mesh materials from the incision line and to prevent the development of chronic pelvic pain syndrome due to rigid fixation, a modification of hybrid pelvic floor reconstruction was performed, where a U-shaped vascularized vaginal flap acts as the main fixation point of the mesh implant. Objective. To study the efficacy and safety of a modified flap technique for unilateral hybrid pelvic floor surgical reconstruction. Patients and methods. A database of 128 case histories was generated. Inclusion criteria: apical anterior prolapse (POP-Q: Ba, C ≥ 0), hybrid pelvic floor surgical reconstruction using mesh endoprosthesis and vascularized vaginal flap performed between May 2020 and September 2022. The variables under study included POP stage, results of the PFDI-20, PISQ-12, and ICIQ-SF questionnaires, intraoperative complications. Patients who underwent surgery were invited for consultation. The following parameters were evaluated: POP stage, presence of mesh erosion, de novo dyspareunia, de novo chronic pelvic pain, de novo functional disorders (an overactive or atonic bladder, stress urinary incontinence (SUI), defecation disorders), repeat surgeries for POP and SUI. The PFDI-20, PISQ-12, and ICIQ-SF questionnaires were filled in. Satisfaction with treatment was assessed using the PGI-I scale. Four patients underwent contrast-enhanced magnetic resonance imaging of the pelvic organs. Results. The results showed a significant improvement in the quality of life after surgery in 113 (96.6%) cases. Only 3 (2.6%) patients had persistent POP symptoms. Of the 117 patients with baseline moderate or severe urinary incontinence, 45 (38.5%) showed improvement in 41 (91.1%) cases. Assessment of the quality of sexual life showed improvement in 27 (77.1%) of 35 patients, and 4 patients returned to sexual activity after surgery. Satisfaction with the results of treatment was noted in 109 (93.2%) patients. Conclusion. Flap modification for unilateral hybrid pelvic floor surgical reconstruction is an effective and safe method of preventing the development of implant-related complications in the correction of POP.
