NCT07836179

Brief Summary

OPTIMUS is an observational study assessing the safety and effectiveness of Optomesh 3D, a shaped surgical mesh used in planned keyhole surgery for a groin (inguinal) hernia. The mesh is placed without additional stitches, tacks, or glue to hold it in position. The study aims to include at least 300 patients from several hospitals. The main question is how often a hernia returns within 12 months after surgery. Researchers will also assess pain, postoperative complications, discomfort in the groin, and the feeling of having a foreign material in the operated area. Participants will provide written consent for the study. Information about their health and operation will be recorded. Follow-up information will be collected through telephone interviews at 7-10 days, 30 days, 3 months, and 12 months after surgery. The results will be assessed in relation to previously published findings on hernia repair.

Outcome Measures

Primary Outcomes (1)

  • Inguinal Hernia Recurrence Within 12 Months

    Percentage of participants reporting recurrence of an inguinal hernia at the operated site within 12 months after the index operation. Information on recurrence is collected through scheduled follow-up telephone interviews.

    From surgery through 12 months after surgery.

Secondary Outcomes (5)

  • Postoperative Groin Pain Intensity

    7-10 days, 30 days, 3 months and 12 months after surgery.

  • Chronic Postoperative Inguinal Pain

    3 months and 12 months after surgery.

  • Early Postoperative Complications

    From surgery through postoperative day 30.

  • Late Postoperative Complications

    Postoperative day 31 through 12 months after surgery.

  • Groin Discomfort

    7-10 days, 30 days, 6 months, and 12 months after surgery.

Study Arms (1)

Optomesh 3D Cohort

Consecutive patients undergoing elective laparoendoscopic inguinal hernia repair using Optomesh 3D without additional mesh fixation at participating centers. Surgery is performed using either the transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP) approach as part of routine clinical care. Participants are followed prospectively for 12 months after surgery to assess hernia recurrence, postoperative pain, complications, groin discomfort, and foreign body sensation.

Device: Optomesh 3D

Interventions

Optomesh 3D (TZMO S.A., Poland) is an anatomically shaped, non-absorbable polypropylene mesh used for inguinal hernia repair. The implant is available in right-sided and left-sided variants and in S/M and L sizes. The mesh is placed in the preperitoneal space during TAPP or TEP repair without additional fixation using sutures, tacks, or glue. The implant variant and size are selected according to the patient's anatomy. Outcomes following mesh implantation are recorded prospectively in this observational study.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Consecutive patients aged 18 years or older, of either sex, presenting to participating surgical centers for elective repair of a primary inguinal hernia. The study includes patients undergoing transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP) repair using Optomesh 3D without additional mesh fixation as part of routine clinical care. Patients meeting the eligibility criteria and providing written informed consent will be enrolled and followed prospectively for 12 months after surgery.

You may qualify if:

  • Age 18 years or older.
  • Male or female patients scheduled for elective repair of a primary inguinal hernia.
  • Eligibility for laparoendoscopic repair using the transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP) approach.
  • Planned use of Optomesh 3D without additional mesh fixation as part of routine clinical care.
  • Written informed consent to participate in the study.

You may not qualify if:

  • Age below 18 years.
  • Emergency surgery, including emergency repair of an incarcerated inguinal hernia.
  • Contaminated surgical field.
  • Recurrent inguinal hernia.
  • Extremely large scrotal hernias requiring additional measures to prevent abdominal compartment syndrome, such as botulinum toxin administration, progressive preoperative pneumoperitoneum, or bowel resection for volume reduction.
  • M3 or combined M3+L1-L3 inguinal hernia according to the European Hernia Society (EHS) classification, confirmed intraoperatively.
