OC-066 TEMPORAL PATTERN FOR REOPERATION OF INGUINAL HERNIA RECURRENCE AFTER A PRIMARY SHOULDICE REPAIR

Abstract

Abstract Aim To identify timing patterns associated with reoperation for recurrence of inguinal hernia in patients undergoing Shouldice repair (RIHaSR) for primary inguinal hernias. Material and methods Patients undergoing a recurrent inguinal hernia repair from 2013–2017 were initially identified. Subgroup analysis of the first recurrence after a Shouldice repair at this institution were selected. Data collection of this subgroup of patients and data analysis were performed. Results From the 138 patients undergoing a re-operation for a first time inguinal hernia recurrence after a Shouldice repair, 125 patients were included in the analysis. The mean age was 50.8±13.9, BMI 24.6+2.6 and 97% were male. Regarding time to surgery for recurrence, the most common interval was in the first 5 years after surgery (37.6% of patients; mode: 1 year; median: 7 years; mean: 13.7±13.8 years). A bimodal pattern of temporal recurrence was noted according to patient age: patients >50 had a peak of reoperation for recurrence in the first 5 years (68% of reoperations for recurrence) with a decrescendo pattern, meanwhile patients <50 demonstrated a stable incidence of reoperation for recurrence in the initial 25 years of follow-up. Conclusions Patients undergoing surgery for RIHaSR presented a bimodal temporal pattern according to age at the time of primary surgery. Patients older than 50y.o. presenting a peak of RIHaSR in the first 5 years after primary surgery in comparison to younger patients that present a relatively stable frequency of reoperation for recurrence up to a 25-year follow-up.
