To evaluate the procedural cost of robotic ventral hernia repair compared with open ventral hernia repair.

Ventral hernia repair is one of the most frequently performed elective surgeries worldwide. The surgical approaches vary depending on the patient characteristics, type, and location the of ventral hernia, as well as the surgeons' preferences and equipment availability.

The choice between an open or minimally invasive approach has been debated for years, and it seems clear that the risk of wound infection is significantly decreased when choosing a minimally invasive approach, whereas there are no significant difference in recurrence rates. In the past decades, the use of a robotic system for ventral hernia repair has gained increasing popularity due to an easy access to the preperitoneal or retromuscular plane with a minimally invasive technique.

Two nationwide cohort studies concluded that length of stay and postoperative morbidity was decreased for robot-assisted repairs compared to open or laparoscopic ventral hernia repairs. Critics of robot-assisted surgery argue that it is time-consuming, too expensive, and that further cost-effectiveness analyses are needed to weigh the clinical benefits.

The aim of these studies was to compare the procedure-specific cost of robot-assisted with open primary ventral and incisional hernia repair and thereafter with laparoscopic repairs.
