Total transvaginal mesh (TVM) technique for treatment of pelvic organ prolapse: a 5-year prospective follow-up study

INTRODUCTION AND HYPOTHESIS

To evaluate clinical effectiveness and complication rates at 5 years following the total Trans Vaginal Mesh (TVM) technique to treat pelvic organ prolapse.

METHODS

Prospective, observational, multi-centre study in patients with prolapse of stage II or higher.

RESULTS

Of the 90 women enrolled in the study, 82 (91%) were available for the 5-year follow-up period. At the 5-year endpoint, success, defined as no surgical prolapse reintervention and leading edge <-1 (International Continence Society [ICS] criteria) or above the level of the hymen, was 79% and 87% respectively. A composite criterion of success defined as: leading edge above the hymen (<0) and no bulge symptoms and no reintervention for prolapse was met by 90%, 88% and 84% at the 1-, 3-, and 5-year endpoints respectively. Quality of life improvement was sustained over the 5 years. Over the 5-year follow-up period, a total of only 4 patients (5%) required re-intervention for prolapse, while a total of 14 patients (16%) experienced mesh exposure for which 8 resections needed to be performed. Seven exposures were still ongoing at the 5-year endpoint, all asymptomatic. Only 33 out of 61 (54%) sexually active patients at baseline remained so at 5 years. De novo dyspareunia was reported by 10%, but no new cases at the 5-year endpoint. One patient reported de novo unprovoked mild pelvic pain at 5 years, 5 reported pains during pelvic examination only.

CONCLUSIONS

Five-year results indicated that TVM provided a stable anatomical repair. Improvements in QOL and associated improvements in prolapse-specific symptoms were sustained. Minimal new morbidity emerged between the 1- and 5-year follow-up.

OBJECTIVES

To describe, in view of the new standardization, the technique for urogenital prolapse repair using a one-piece synthetic mesh.

MATERIALS AND METHODS

The history and development steps through which the Tension free Vaginal Mesh (TVM) technique emerged are described. The use of a mesh was prompted by the 20-30% recurrence rate associated with conventional repair techniques. Selection of the type of mesh is discussed. Non-absorbable synthetic meshes have shown their usefulness in visceral surgery. A list of materials along with their respective advantages and inconveniences is reviewed and particular emphasis is put on both the tolerance and erosion issues, the latter being specific to the vaginal route. The TVM Group selected a one-thread polypropylene mesh, Prolene Soft, which seemed the most appropriate for the transvaginal approach of prolapse surgical repair. The prosthesis and its design rationale are described. Full details are given on the consecutive intervention steps and underlying concepts.

RESULTS

The relevant literature is scarce and there is a lack of methodologically sound studies validating the materials and techniques used. After completion of a first step of technique refinement and feasibility assessment involving about 300 surgical interventions, the authors initiated a prospective multicenter study. Clinical outcome assessments using feasibility, complications, and efficacy endpoints will be published after twelve months, three years, and five years of follow-up.

CONCLUSION

Fruitful reasoning led to the development of the TVM technique of complete surgical repair of genital prolapse, which uses a synthetic materiel carefully selected after several tests. All surgeons can apply this technique after a short training period.

[Painless hysterectomy: an innovative technique]

We describe a completely innovative approach to vaginal hysterectomy where the surgeon and anesthetist work in tandem to ensure that the patient receives optimal pain management: combined use of general and long-acting local-regional anesthesia and use of the "bi-clamp" procedure for bipolar electrosurgery which has proved to be a significant technical improvement. In this way, pain, until now the major drawback of this procedure, is really decreased allowing a better acceptance of the procedure and a greatly improved quality of life.
