Sikkerhed og effekt af 3DMax™ MID anatomisk net (BD, USA) ved laparoskopisk-endoskopisk lyskebroksoperation - Multicenter, prospektiv observationsundersøgelse (3DMS)
Sikkerhed og effekt af 3DMax MID anatomisk net (BD, USA) ved laparoendoskopisk lyskehernieoperation: Et multicenter prospektivt observationskohortestudie
This is a multicenter, prospective, observational cohort study evaluating the safety and efficacy of the 3DMax MID Anatomical Mesh (BD, USA) in laparoendoscopic inguinal hernia repair. Adult patients undergoing elective transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP) repair will be enrolled and followed according to routine clinical practice.
The primary objective is to assess the inguinal hernia recurrence rate within 12 months after surgery. Secondary objectives include evaluation of postoperative pain, groin discomfort and foreign body sensation, as well as early and late postoperative complications.
All participating patients will receive the 3DMax MID Anatomical Mesh as part of standard care. No additional experimental procedures are planned. Clinical data will be collected at baseline and during predefined follow-up contacts (early postoperative period, 1 month, 3 months and 12 months) using standardized forms and patient interviews.

Detaljeret beskrivelse
Laparoendoscopic techniques such as transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) repair are widely used for the treatment of inguinal hernia and are associated with faster recovery and lower rates of chronic pain compared with open repair in appropriately selected patients. Mesh reinforcement is a key component of these procedures. Three-dimensional, anatomically contoured meshes have been developed to improve conformability to the myopectineal orifice and to provide stable coverage of the inguinal region, potentially reducing the need for additional fixation and lowering the risk of chronic postoperative pain.
The 3DMax MID Anatomical Mesh (BD, USA) is a medium-weight, macroporous, pre-shaped polypropylene mesh designed specifically for inguinal hernia repair. Its three-dimensional configuration and recoil properties are intended to facilitate correct positioning and stable coverage of the inguinal anatomy during laparoendoscopic procedures.
This multicenter, prospective, observational cohort study will include consecutive adult patients undergoing elective TAPP or TEP inguinal hernia repair in participating centers, in whom the operating surgeon has decided to use the 3DMax MID Anatomical Mesh as part of routine practice. No randomization or control group is planned, and no interventions outside standard care will be performed.
Data will be collected from medical records and structured follow-up contacts (early postoperative check, approximately 30 days, 3 months and 12 months after surgery). The primary endpoint is hernia recurrence within 12 months. Secondary endpoints include postoperative pain, groin discomfort, foreign body sensation and early or late postoperative complications. Study data will be recorded in a standardized database and analyzed descriptively to characterize the safety profile and clinical performance of the 3DMax MID Anatomical Mesh in real-world practice.

3DMax MID TAPP/TEP
Adult patients undergoing elective laparoendoscopic inguinal hernia repair (TAPP or TEP) with implantation of the 3DMax MID Anatomical Mesh (BD, USA) as part of routine clinical practice. No randomization or control group is used; all enrolled participants receive the same type of mesh according to the treating surgeon's standard technique. |
Implantation of a pre-shaped, medium-weight, macroporous polypropylene anatomical mesh (3DMax MID Anatomical Mesh, BD, USA) during elective laparoendoscopic inguinal hernia repair (TAPP or TEP) as part of routine clinical practice. No additional experimental procedures beyond standard surgical care are planned.
