Abstract

PURPOSE
We conducted a multi-institutional analysis to establish the epidemiological characteristics of recurrent inguinal hernia following hernia repair in patients across 4 institutions in Korea.
METHODS
The retrospectively reviewed data included patient characteristics, hernia location, year of primary operation, type of hernia, timing of recurrence, primary operation type, and whether a mesh was used.
RESULTS
Among 4,604 patients who underwent hernia repair surgery, 255 patients (5.5%; 13 females and 242 males; mean age, 63 years) were found to have recurrent hernia from January 2010 to April 2017. Recurrent indirect inguinal and direct hernias were observed in 47.1% and 49.4% of the patients, respectively. The recurrence of hernias within 1 year of surgery was the highest at 17.25%. Early and late recurrences was observed in 23.5% and 66.5% of the patients, respectively. Among the patients, 81.6% underwent open hernia repair at the time of initial surgery.
CONCLUSION
Recurrence of hernia is most common in the first year after the initial surgery, and 23.5% of recurrent inguinal hernia was developed within 2 years. Patients underwent surgery after an average of 116 months (median value, 64 months) following the first operation. In patients with recurrent hernia, direct hernia was seen more frequent than indirect hernia whereas indirect hernia occurred more in patients with primary hernia.
