Risk factors for recurrence after laparoscopic inguinal hernia repair: a 5-year retrospective cohort study
Main Article Content
Abstract
Background: The benefits of laparoscopic inguinal hernia repair are multiple; however, the recurrence rate is still controversial and under debate.
Objective: The aim of this study is tu analyze the risk factors associated with long-term recurrence after laparoscopic inguinal hernia repair. Material and methods: The cohort was made up of consecutive patients undergoing transabdomi- nal preperitoneal approach between December 2012 and May 2012, with a minimum follow-up of 6 months. The sample was divided into two groups: G1 (patients with recurrence) and G2 (patients without recurrence). The demographic and clinical variables and the outcomes at 5 years were analyzed.
Results: A total of 717 inguinal hernia repairs were performed in 443 patients. Smoking habits, pre- vious recurrence, mesh size < 12 ×15 cm and surgeries carried out by surgical teams performing < 30 procedures per year were significantly associated with recurrence on univariate analysis (p < 0.05). but only smoking habits and surgeries performed by less experienced surgeons showed statistical sig- nificance on multivariate analysis (p < 0.01). Recurrence rate was 1.5% at years and increased to 2.6% (n = 19) at 5 years.
Conclusion: Extending the follow-up period beyond 2 years after laparoscopic inguinal hernia repair allows a more accurate detection of the recurrence rate. In this series, smoking habits and surgeries performed by less experienced surgeons were significantly associated with recurrences
