Previous research has shown that the repair of a recurrent inguinal hernia is subject to a greater risk of additional recurrence. Further, bilateral inguinal hernia is subject to a greater recurrence risk than unilateral inguinal hernia. These increased risks may be due to certain anatomical difficulties that complicate the surgical approach in these types of patients. Some clinicians have suggested that laparoscopic approaches are better suited to recurrent and bilateral hernias, and in we delineate separate comparisons for primary, bilateral, and recurrent hernia.
Of the 392 patients who underwent surgery, 161 (90.81 %) of 177 in the HW group and 195 (90.69 %) of 215 in the LW group were examined according to protocol, a median of 62 (range 57-66) months after hernia repair. There was no difference in the recurrence rate (1.9 % LW vs. 0.6 % HW; P = 0.493). There were 24 deaths in the follow-up period, but these had no connection to the surgery. The patients treated with LW mesh reported less pain in the early postoperative period. After five years of follow-up, the intensity and the presence of pain did not differ between groups (5 patients in the LW and 4 patients in the HW group). Average pain, (VAS score), was also similar in the LW and HW group (2.25 vs. 2.4) at the fifth year postoperatively.
