Mesh-related complications from reconstructive surgery for pelvic organ prolapse in Chinese patients in Hong Kong.

Introduction: Mesh-related complications from reconstructive surgery for pelvic organ prolapse are of international concern. The present study aimed to review the incidence, management, and surgical outcomes of mesh-related complications in a Chinese population compared with existing studies involving Western populations.
Methods: This was an analysis of a prospectively collected cohort. Laparoscopic sacrocolpopexy, laparoscopic hystercolposacropexy, or transvaginal mesh surgery were offered with or without concomitant vaginal hysterectomy or continence surgery. Patients were followed up and mesh-related complications were noted.
Results: Overall, 276 Chinese women who received mesh surgery were included for data analysis. There were 22 mesh-related complications found during a mean follow-up period of 40 months. Mesh exposure accounted for 20 these complications; significantly more occurred after transvaginal than after abdominal mesh surgery (16 vs 4; P=0.01). Median duration from primary operation to the time of mesh exposure detection was 12 months (interquartile range=4.8-32.8 months). Ten patients required surgical excisions of exposed mesh. The re-operation rate after mesh complications was 6.7% (9/134) for transvaginal mesh surgery and 1.4% (2/142) for laparoscopic sacrocolpopexy (P=0.03). All excisions were performed transvaginally and 95% remained well after surgery. Occurrence of mesh exposure was higher in transvaginal mesh surgery (adjusted odds ratio=6.1; P=0.008), in sexually active patients (adjusted odds ratio=5.4; P=0.002), and in obese patients (adjusted odds ratio=3.7; P=0.046). Over 90% were satisfied with the outcome, regardless of mesh complications.
Conclusions: The rates of mesh exposure and re-operation were consistent with those reported in the literature, suggesting no significant differences in outcome between Chinese and Western patients for this type of surgery.
