swing-mesh™ study (sms).

Conditions: Inguinal Hernia

Summary: this multicenter, prospective observational study aims to assess the safety and efficacy of the swing-mesh™ implant (tht bioscience™, distributed by b. braun™, france) for laparoscopic-endoscopic inguinal hernia repair using tapp or tep techniques. swing-mesh™ is a lightweight, macroporous, three-dimensional mesh designed to conform anatomically to the myopectineal orifice without requiring fixation. eligible adult patients undergoing elective repair will receive the implant. the primary endpoint is hernia recurrence within 6 months. secondary endpoints include postoperative pain, groin discomfort, and early and late complications. the study will provide clinical evidence regarding the non-inferiority of this spatial, fixation-free mesh compared to standard devices in minimally invasive hernia surgery.

laparoscopic techniques such as tapp and tep are currently recommended as the standard approach for inguinal hernia repair due to faster recovery, reduced postoperative pain, and lower complication rates compared to open surgery. to address the limitations of flat meshes in minimally invasive procedures, three-dimensional implants have been developed. these are better suited to the anatomical structure of the myopectineal orifice (mpo), reducing the risk of mesh migration without the need for fixation. swing-mesh™ is a new lightweight, macroporous 3d implant introduced to the polish market in 2025. its structure is based on thermally modified polypropylene fibers, eliminating the need for rigid stabilizing rings. the implant is suitable for both right- and left-sided hernias. the aim of this study is to assess the safety and clinical performance of swing-mesh™ in real-world settings. the primary endpoint is the hernia recurrence rate within 6 months. secondary outcomes include postoperative pain, early and late complications, and patient-reported groin discomfort. this is a prospective, multicenter, observational cohort study. consecutive patients undergoing elective laparoscopic inguinal hernia repair will be enrolled after providing informed consent. the swing-mesh™ (15×11 cm or 16×12 cm) will be implanted without fixation. selected surgical steps will be documented (photo/video), anonymized, and stored on a secure research platform. follow-up will be conducted at 7-10 days, 30 days, 3 months, and 6 months postoperatively. data will be collected via structured telephone interviews or in-person visits, as needed.
