Surgical Aspects of Recurrent Inguinal Hernia in Adults.

Surgeons occasionally encounter a case of recurrent hernia in adult patients after the primary repair, and these cases are challenging to manage appropriately. This study was conducted to describe the clinical nature of recurrent inguinal hernia, compare the results of management, and identify the relationship between the specific risk factors and the occurrence of recurrent hernia. Retrospectively reviewed 58 patients who underwent the inguinal herniorrhaphy for recurrent hernia in a single institution. Analyzed clinical characteristics of recurrent hernia and tried to verify the relationship between smoking, obesity, and occurrence of recurrent hernia. Recurrent inguinal hernia was 13.5 per cent of all hernia repairs in the study period. Most of the recurrence was the first event (74.1%) and showed an interval to recurrence with a mean duration of 40.7 months. There was no significant difference in procedure time, development of postoperative complications, and duration of hospital stay according to the procedure. Compromise of smoker and overweight was significantly higher in the recurrent group (P < 0.05). Surgeons should be aware of the increased risk for recurrence in adult inguinal hernia patients when they smoke or are overweight (body mass index ≥ 25 kg/m2), also it needs to follow-up during the adequate period.
