Comparison of non-woven and woven polypropylene mesh in laparoscopic inguinal hernia repair

Abstract

Objective To observe the treatment of inguinal hernia with non-woven polypropylene and woven polypropylene mesh in TAPP, and to explore the clinical effect of different types of polypropylene mesh in the treatment of inguinal hernia. Methods A retrospective analysis of the medical records of 136 patients with inguinal hernia underwent TAPP with two types of polypropylene meshes from May 2016 to January 2018, with 65 cases using non-woven polypropylene mesh (experimental group) and 71 cases of woven polypropylene mesh (control group). The safety and short-term outcome of the different types of polypropylene mesh in the treatment of inguinal hernia were compared. Results All the 136 patients successfully completed the operation. The operation time of the experimental group was 55 (35, 75) minutes, the postoperative hospital stay was 2 (1, 3.5) days, the intraoperative blood loss was 5 (2, 10) ml; and the control group was operated for 45 (35, 60) minutes, the hospital stay was 2 (1, 3) days, and the intraoperative blood loss was 3 (2, 5) ml. There were no significant differences between the two groups. Seroma of inguinal region was occurred in 5 cases of the experimental group, and 8 cases of the control group. There was no chronic pain in the experimental group and 5 cases of chronic pain in the control group. There were 1 case of local foreign body sensation in the experimental group and 7 cases in control group. The differences were not statistically significant. Conclusion Non-woven polypropylene mesh is effective in the application of TAPP repair and it is worthy of clinical promotion. Key words: Hernia, inguinal; Herniorrhaphy; Laparoscopes
