Background
The advantage of single-port total extra-peritoneal (TEP) inguinal hernia repair over the conventional technique is still debatable. Our objective was to compare the outcomes of TEP inguinal hernia repair using either a single-port or conventional surgical technique, in two blind randomized groups of patients.
Methods
In this prospective, randomized, double-blind, controlled clinical trial, 100 patients undergoing surgery for unilateral inguinal hernia were randomized into two groups: One group underwent conventional laparoscopic TEP inguinal hernia repair, while the other was selected for single-port TEP repair. Primary endpoint is postoperative pain (VAS), while secondary endpoints are recurrence, chronic pain and complications.
Results
From 100 patients, 49 underwent single-port hernia TEP repair, 50 had conventional three-port TEP hernia repair, and one patient declined to participate after randomization. The two groups were comparable in terms of patient demographics and operative findings. Mean operative time was 49.1(±13.8) min in the conventional group and 54.1(±14.4) min in the single-port group (p = 0.08). Mean hospital stay was 19.7(±5.8) h in the conventional group and 20.5(±6.4) h in the single-port group (p = 0.489). No major complications and no recurrence reported at 11-month follow-up. No statistically significant difference noted in postoperative pain between the two groups at regular intervals.
Conclusions
The outcomes after laparoscopic TEP inguinal hernia repair with a single-port device are similar but not superior to the conventional technique.
