Purpose
The advantages of minimally invasive inguinal hernia repair (MIHR) over open hernia repair (OHR) continue to be debated. We compared MIHR to OHR by utilizing the Army Physical Fitness Test (APFT) as an outcome measure.
Methods
The APFT is a three-component test scored on a normalized 300 point scale taken semiannually by active-duty military. We identified 1119 patients who met inclusion criteria: 588 in the OHR group and 531 in the MIHR group. Changes in APFT scores, time on post-operative duty restrictions (military profile), and time interval to first post-operative APFT were compared using regression analysis.
Results
Postoperatively, no APFT score change difference was observed between the OHR or MIHR groups (− 7.3 ± 30 versus − 5.5 ± 27.7, p = 0.2989). Service members undergoing OHR and MIHR underwent their first post-operative APFT at equal mean timeframes (6.6 ± 5 months versus 6.7 ± 5.1, p = 0.74). No difference was observed for time in months spent on an official temporary duty restriction (military profile) for either OHR or MIHR (0.16 ± 0.16 versus 0.15 ± 0.17, p = 0.311). On adjusted regression analysis, higher pre-operative APFT scores and BMI ≥ 30 were independently associated with reduction in post-operative APFT scores. Higher-baseline APFT scores were independently associated with less time on a post-operative profile, whereas higher BMI (≥ 30) and lower rank were independently associated with longer post-operative profile duration. Higher-baseline APFT scores and lower rank were independently associated with shorter time intervals to the first post-operative APFT.
Conclusion
Overall, no differences in post-operative APFT scores, military profile time, or time to first post-operative APFT were observed between minimally invasive or open hernioplasty in this military population.
