Background
Developments in inguinal hernia surgery have substantially lowered recurrence rates, yet recurrences remain an important outcome parameter of inguinal hernia repair. The aim of this study was to analyze the characteristics of all reoperated groins after endoscopic totally extraperitoneal (TEP) inguinal hernia repair in a high-volume hernia clinic in the Netherlands.
Methods
All groins with recurrence-like symptoms reoperated after previous TEP inguinal hernia repair between January 2006 and December 2016 were analyzed. Patient characteristics, imaging findings, primary hernia type, time to recurrence and recurrence type were assessed.
Results
A total of 137 groins were reoperated in 130 patients. The median age at the TEP procedure was 55 years [interquartile range (IQR) 45–64 years]. Fifty-seven groins were initially part of a bilateral procedure (42%). Median time until recurrence was 9 months (IQR 4–26 months). Reoperation findings were a hernia recurrence in 76%, an isolated lipoma in 18%, and no recurrence or lipoma in 6%. The majority of hernias recurred at their initial site (70%), of which the greatest part involved direct hernias. Isolated lipomas were more frequently seen after indirect hernia repair.
Conclusions
Inguinal hernia recurrences were still observed in this high-volume hernia clinic. Recurrences were most frequently seen at their initial hernia site, the majority involving direct hernias. Isolated lipomas presenting as a pseudorecurrence were most frequently seen after correction of indirect hernias. In accordance with the current guidelines, reducing recurrence rates can be achieved by mesh fixation in bilateral, large and direct defects and by thoroughly reducing lipomas.
