A prospective Study on Femoral Hernia Repair: Is the Inguinal Better Than The Infrainguinal Approach?

Femoral hernia repair has various surgical methods. However, controversy still exists regarding the best method for management. This study aimed to compare the infrainguinal with the inguinal approach in the treatment of femoral hernias.

Eighty patients with primary unilateral femoral hernias were prospectively randomized to either the infrainguinal (n = 40) or inguinal approach groups (n = 40). Patient demographics, operative time, duration of hospital stay, postoperative complications, and recurrence rate were recorded.

There were no statistically significant differences between both study groups with respect to the patients' demographics and associated comorbidities. Regarding inpatient outcomes, there were no differences between the infrainguinal and inguinal approach groups concerning the postoperative duration of stay (P = 0.248), urinary retention (P = 0.494), superficial wound infection (P = 0.494), seroma (P = 0.615), foreign body sensation (P = 0.615), and chronic pain (P = 0.359). However, total complications were encountered in 3 patients (7.5%) in the infrainguinal approach group compared to 11 patients (27.5 %) in the inguinal approach group (P = 0.037). Also, the mean operative time was significantly shorter in the infrainguinal approach group compared to that in the inguinal group (P < 0.001). Throughout the 15 mo median follow-up duration, there was no recurrence in the inguinal approach group and one (2.5%) recurrence in the infrainguinal approach group (P = 1.000).

In patients undergoing elective primary femoral hernia repair, the infrainguinal approach has a similar clinical curative effect to that of the inguinal approach. However, the former has the advantages of simple operation, short operation time, and fewer complications.
