Clinical and Patient-Reported Outcomes after Absorbable Strap Fixation for Ventral Hernia Repair

Various mesh fixation methods are employed by surgeons during ventral hernia repair. These may include tacks, straps, sutures, glue, or a combination of methods. One of these choices is an absorbable fixation device, Securestrap® (Ethicon Inc., Somerville, New Jersey), consisting of an absorbable copolymer barbed U-shaped strap with a spring-loaded deployment system.

The International Hernia Mesh Registry is a prospective multi-center registry, designed to collect longitudinal data on hernia repair methods, products, and outcomes. Patients complete the Carolinas Comfort Scale™ (CCS) (The Charlotte-Mecklenburg Hospital Authority, Charlotte, North Carolina) pre-operatively, and at one month, six months, and 12 months post-operatively. Symptomatic patients defined as responding >1 to any CCS™ question. Statistical comparison of symptom frequency was made with the McNemar test and Kaplan Meier methods to determine the recurrence rate up to 365 days.

Patients were enrolled at 16 centers. Data was available on 100 of the 203 patients at six months and on 119 patients at 12 months. Demographics: mean age of 52.7 (13.2 standard deviation[ SD]); mean body mass index (BMI) of 33.2 (7.5 SD) kg/m2; 64.3% having a BMI over 30kg/m2; male patients 47.4%; 16.7% for recurrent hernias. Mesh fixation with straps alone in 48.3% of cases or straps and sutures in 51.7% of cases. Percentage of patients with symptomatic pain decreased slightly from baseline to one month (70.0 vs. 60.6, p=0.0782) and significantly from one month to six months (60.6% symptomatic vs. 23.2%; p=0.0004). From six months to twelve months, the change in percentage of symptomatic patients was not significant (23.2% vs. 28.7%; p=0.8084). Similar results were observed with symptomatic CCS™ movement limitations. Overall recurrence rate at 12 months was 4.72% (2.39%-9.22%).

Mesh fixation with straps with or without additional sutures is associated with significant improvements in patient-reported pain and movement limitation from baseline to six months post-operative.
