Objective:
To estimate the long-term incidence and characteristics of graft-related complications, rate of reintervention for graft-related complications and prolapse, and subjective and anatomical outcomes after laparoscopic sacrocolpopexy with heavier-weight (more than 44 g/m2) compared with lightweight (28 g/m2) polypropylene mesh, the latter with resorbable poliglecaprone component.
Methods:
We conducted a single-center study that compared two consecutive prospective cohorts of patients who were undergoing laparoscopic sacrocolpopexy for symptomatic stage 2 or greater cervical or vault prolapse, by using either heavier-weight polypropylene mesh or lightweight polypropylene mesh at a similar duration of follow-up. The primary outcome was the occurrence of graft-related complications and their nature. Secondary outcomes included reinterventions for graft-related complications, recurrent apical prolapse, a subjective outcome (PGIC [Patient Global Impression of Change] score 4 or higher), and an anatomical outcome (point C -1 cm or greater).
Results:
We identified consecutive patients: 101 were implanted with heavier-weight polypropylene, and 238 were implanted with lightweight polypropylene; all were audited at comparable follow-up times (heavier-weight mesh: 97 months [interquartile range 16 months]; lightweight mesh: 92.5 months [interquartile range 58 months]). Graft-related complications were more frequent in patients with heavier-weight than lightweight mesh (22.8% [23/101] vs 7.3% [13/178]; hazard ratio [HR] 3.3, 95% CI 1.6-7.1), more frequently symptomatic (heavier-weight mesh: 16.8% [17/101] vs lightweight mesh: 2.8% [5/178]; HR 6.0, 95% CI 2.5-14.3), and more frequently lead to reintervention for graft-related complications (heavier-weight mesh: 18.8% [19/101] vs lightweight mesh: 2.1% [5/238]; HR 4.6, 95% CI 1.9-11.2). The vast majority of patients improved (PGIC score 4 or higher), without difference between groups (heavier-weight mesh: 71/84 [84.9%]; lightweight mesh: 154/178 [86.5%]; HR 0.8, 95% CI 0.6-1.1); neither was there a difference in anatomical failure rate (heavier-weight mesh: 1/60 [1.7%] vs lightweight mesh: 8/131 [6.1%]; HR 0.3, 95% CI 0.1-1.4). Reoperations for recurrent vault prolapse were scarce (0.0% in heavier-weight mesh, vs 0.4% in lightweight mesh).
Conclusion:
In two consecutive cohorts, the number of graft-related complications, symptomatic graft-related complications, and reinterventions for graft-related complications were higher in patients implanted with heavier-weight polypropylene than when lightweight polypropylene was used. There were no differences in subjective, objective outcomes, and reoperation rates for prolapse.
