Abstract

Background

Single-port laparoscopic surgery (SPLS) has been introduced for totally extraperitoneal (TEP) inguinal hernia repair. Clinically, however, the benefits of single-port TEP (SP TEP) are unclear. This study aimed to compare short-term surgical outcomes between SP TEP and conventional laparoscopic TEP(CL TEP) inguinal hernia repair.

Methods

Between January 2013 and February 2015, 99 men with primary unilateral inguinal hernia were randomized to the single-port or conventional 3-port TEP procedures. The primary end point was postoperative pain. Secondary end points were complications, postoperative hospital stay, days to return to daily normal activities, cosmesis, and quality of life (QOL).

Results

We randomized 50 patients to SP TEP and 49 to CL TEP repair. The SP TEP group patients had significantly lower pain scores (visual analog scale) 7 days postoperation (p = 0.017). However, there were no significant differences between the two groups in postoperative pain scores 24 h (p = 0.44) and 4 weeks (p = 0.677) after operation and analgesic requirements on the operation day (p = 0.303) and 7 days after the operation (p = 0.204). Operation time, postoperative hospital stay, and complications were comparable between the two groups. The days to return to daily normal activities, QOL, and cosmetic satisfaction were not different between the two groups.

Conclusion

The outcomes of SP TEP hernia repair for operation time and morbidities were comparable to CL TEP, and postoperative pain was lower at 7 days than in CL TEP hernia repair. The SP TEP technique can be recommended as an alternative treatment for inguinal hernia repair in experienced hands.
