Summary

In this randomized clinical trial, the investigators will compare the conventional open repair for hernia in the anterior abdominal wall with the robotic-assisted approach. 60 patients with midline abdominal wall defects will be randomized to either open or robotic-assisted surgery. The investigators will examine short and long-term complications through follow-up with clinical assessment as well as patient-reported outcome measures including pain, cosmetic appearance, and overall patient satisfaction. Furthermore, the investigators will study the difference in surgical stress response between the two methods measured from a variety of different biomarkers before and after the operation. A cost-effective analysis will be conducted for the robotic and open procedure.

Detailed description

Ventral hernias occur in up to 25% of the population. They are diverse in severity ranging from small umbilical hernias to large abdominal wall defects that may result in loss of domain. Approximately one-third are incisional hernias. Incisional hernias are usually more complex due to complications from previous surgery. The procedure may be complicated as a result of intraabdominal bowel adhesions and adhesions within the hernial sac. These factors cause discomfort and may complicate the repair. Ventral hernias may be repaired either through a minimally invasive laparoscopic procedure or an open approach. The laparoscopic repair was introduced in the 1990s and in 2003 the first robotic-assisted procedure was described in a porcine model. In 2012 the first series of robotic repairs were reported in humans. Due to the superior flexibility of the robotic instruments, there is a substantial interest in harnessing the advantages of the robotic platform. Because robotic repair differs in several technical aspects from the open approach, it is important to determine whether the short and long-term results differ between the two procedures. Furthermore, it remains unresolved whether the robotic procedure is able to provide comparable outcomes to the open repair when assessed for quality-of-life outcome measures. These questions are important to address in order to determine the most appropriate surgical options for individual patients.
