Several randomized trials comparing self-gripping mesh with polypropylene (PL) mesh in Lichtenstein hernioplasty revealed that the self-gripping mesh significantly reduced the operation time. In these studies, some enrolled only male patients, and in others, the proportion of women was extremely low. The aim of this research was to compare outcomes after self-gripping mesh repair with PL mesh secured with sutures in female Lichtenstein hernioplasty. Female patients with primary unilateral inguinal hernia were assigned randomly to undergo Lichtenstein hernioplasty with a self-gripping ProGrip (PG) mesh or a sutured PL mesh, followed-up at one week, one month, three months, one year, and two years. Demographics, hernia characteristics, and operative outcomes data were analyzed. Pain was assessed with a visual analog scale (0-10), and quality of life (QOL) was estimated by a 36-item short-form general survey (0-26). Forty eight patients in the PG group and 51 participants in the PL group completed the follow-up. The operation time of the PG (54.1 ± 12 minutes) group was significantly shorter than that of the PL (60.9 ± 11.3 minutes) group ( = 0.045). At the one-month follow-up, the incidence of foreign body feeling in the PG group was significantly higher than that in the PL group ( = 0.031), whereas no significant difference was observed in visual analog scale ≥3 and QOL. In a follow-up of three months, one year, and two years, there was no significant difference in foreign body feeling, chronic pain, QOL, and recurrence between two groups. The surgical outcomes of self-gripping mesh are comparable to those of the ordinary PL mesh with a reduced operation time in female Lichtenstein hernioplasty.
