Outcome Measures

Primary Outcomes (3)

  • Pain scores

    Subject reported pain scores assessed by the Subject-Reported Outcome Measurement Information System (PROMIS) Pain Intensity 3a survey.

    4 weeks

  • Non-opioid prescription pain medication usage

    Non-opioid prescription pain medication usage related to the retromuscular ventral hernia repair

    4 weeks

Secondary Outcomes (10)

  • Narcotic usage

    3 months

  • Non-opioid prescription pain medication usage

    3 months

  • Over the counter pain medication usage

    4 weeks

  • Need for refill prescription pain medication

    4 weeks

  • PROMIS 3a pain scores

    4 weeks

  • +5 more secondary outcomes

Study Arms (2)

Retromuscular ventral hernia repair

These subjects will undergo an open, a laparoscopic, or a robotic-assisted retromuscular ventral hernia repair.

Procedure: Open retromuscular ventral hernia repairProcedure: Laparoscopic retromuscular ventral hernia repairDevice: Robotic-assisted retromuscular ventral hernia repair

Retromuscular TAR ventral hernia repair

These subjects will undergo an open or a robotic-assisted retromuscular transversus abdominis release (TAR) ventral hernia repair.

Procedure: Open retromuscular ventral hernia repairDevice: Robotic-assisted retromuscular ventral hernia repair

Interventions

With the subject under general anesthesia, a single incision is made in the abdomen. The retrorectus space is developed for mesh placement to repair the defect. The repair technique will be per the surgeon's standard of care.

Retromuscular TAR ventral hernia repairRetromuscular ventral hernia repair

With the subject under general anesthesia, several small incisions are made in the abdomen. Ports are placed, the abdomen is insufflated, and laparoscopic instruments as well as a laparoscope are inserted to complete the repair. The retrorectus space is developed for mesh placement to repair the defect. The repair technique will be per the surgeon's standard of care.

Retromuscular ventral hernia repair

With the patient under general anesthesia, several small incisions are made in the abdomen. Ports are placed, the abdomen is insufflated, and the da Vinci Robotic Surgical System (Intuitive) is docked to the subject and used to complete the procedure. The retrorectus space is developed for mesh placement to repair the defect. The repair technique will be per the surgeon's standard of care.
