    Abstract:
    PURPOSE: The purpose of this study was to compare laparoscopic total extraperitoneal (TEP) hernia repair procedures with or without mesh fixation for non-recurrent inguinal hernia. METHODS: 100 male patients with non-recurrent inguinal hernia (62 unilateral and 38 bilateral) were included in the study. The patients were randomly assigned to either the mesh fixation group (n = 50) or the mesh non-fixation group (n = 50). The operative and follow-up data of the two groups were analyzed and compared in terms of recurrence rates, postoperative pain, length of hospital stay, and postoperative changes in testicular arterial blood flow. RESULTS: Pain scores were significantly higher in the mesh fixation group prior to discharge and at the 1st postoperative month (p = 0.034 and 0.001, respectively). Necessity to use narcotic analgesics was higher in the fixation group prior to discharge (p = 0.025). Urinary retention was significantly more frequent in the fixation group than in the non-fixation group. (p = 0.007). The mean operative time and length of hospital stay were similar in both groups. Preoperative and postoperative measurements of testicular arterial blood flow showed a substantial but not statistically significant difference for the frequency of impairment (14.2% in the fixation group and 5.8% in the non-fixation group) (p = 0.176). At long-term follow-up, no recurrence and no nerve injury were determined. CONCLUSION: Fixation of the mesh to the abdominal wall has been associated with various postoperative complications for no additional benefit in lowering recurrence rates. For non-recurrent inguinal hernia, non-fixation of the mesh is safe and reliable. Further studies with larger sample sizes are necessary for subgroup analyses.
