This study aimed to evaluate the efficacy and outcome of total extraperitoneal (TEP) herniorrhaphy in patients with recurrent inguinal hernia.
Between January 2009 and September 2014, 472 patients underwent TEP henriorrhaphy for inguinal hernia. In this cohort, 38 patients who ever received previous traditional open herniorrhaphy were defined as study group. For the comparison group, 76 patients who did not have previous hernia repair history were randomly selected to match the study group in terms of age, sex and laterality of inguinal hernia. Perioperative data including patients’ demographics, operative time, pain scale, conversions, length of hospital stay, recurrence, and complications were recorded and analyzed.
In this study, the mean follow-up period were 24.5 months (7-66). The operative time in study group and comparison group were 99.7 and 90.2 minutes, respectively (p=0.8). The pain scale was higher in study group than that in comparison group, but not significant (2.8 vs. 2.3, p=0.7). No conversion was needed in both groups. The patients in both groups could discharge on the first postoperative day, without exceptions. The hernia recurrence rate were similar between study group and comparison group (p=0.7), so as the complication rates (p=0.2).
TEP herniorrhaphy for patients with recurrent inguinal hernia is safe and effective. In this study, no significant differences were observed between the two groups in terms of operating time, pain scale, analgesic use, hospital stay and complications.
