A 45-year-old man with a 2-year history of asymptomatic right indirect inguinal hernia is counseled regarding surgical repair. He is concerned about recurrence rates. According to current evidence-based guidelines, which repair technique offers the lowest recurrence rate for primary inguinal hernia?

## Inguinal Hernia Repair Techniques and Recurrence Rates The choice of repair technique significantly impacts recurrence rates. Current meta-analyses and guidelines provide clear evidence on comparative outcomes. ### Recurrence Rates by Technique (Primary Inguinal Hernia): | Technique | Recurrence Rate | Notes | |-----------|-----------------|-------| | **Robotic RAMP** | **0.5–2%** | **Lowest recurrence; retrorectus placement; higher cost** | | Lichtenstein (open mesh) | 1–3% | Gold standard; cost-effective; good outcomes | | TEP/TAPP (laparoscopic) | 1–3% | Bilateral repair advantage; steep learning curve | | Shouldice (tissue repair) | 5–10% | Higher recurrence; rarely used now | | Tissue repair (open) | 10–15% | Obsolete for primary repair | **Key Point:** Robotic-assisted RAMP repair places mesh in the retrorectus space (between rectus abdominis and posterior rectus sheath), providing superior fascial coverage and the lowest recurrence rates. This technique combines the advantages of open (direct visualization, no peritoneal breach) and minimally invasive approaches (retrorectus placement). **Clinical Pearl:** While Lichtenstein repair remains the most commonly performed technique globally due to cost-effectiveness and acceptable outcomes, robotic RAMP offers superior recurrence rates and is increasingly adopted in high-volume centers. **High-Yield:** For NEET PG, remember: **Robotic RAMP > Lichtenstein ≈ TEP > Shouldice > Tissue repair** in terms of recurrence rates.
