Robotic Versus Laparoscopic Ventral Hernia Repair

December 16, 2019


The University of Texas Health Science Center, Houston is hosting a clinical trial on the advantages of robotic versus laparoscopic ventral hernia repair. Ventral hernia repairs increase the likelihood for disease by surgical site infection, hernia recurrence, and reoperation.  Researchers are investigating claims that minimally invasive surgery has less chance for surgical site infection and decreases the amount of time spent in the hospital. The study’s estimated date of completion is April 30, 2023.


Study Information

There will be an estimated 120 participants in this study. Participants will be randomly assigned to one of two groups: those receiving a laparoscopic ventral hernia repair and those receiving a minimally-invasive, robotic-assisted ventral hernia repair.  Patients will be observed at points of 1 month, 90 days, 1 year, 2 years, and 3 years after surgery for:

  • Surgical site infection
  • Surgical site occurrence
  • Hernia recurrence
  • Patient centered outcomes
  • Cost


Inclusion Criteria

All sexes, ages 18 years and older, who are undergoing elective ventral hernia repair and are considered suitable for minimally invasive repair. 


Exclusion Criteria

Those who are not allowed to participate include:

  • Patients unlikely to survive after 2 years based upon surgeon judgment (e.g. advanced cirrhosis or metastatic cancer)
  • Patients who are unlikely to follow-up (e.g. lives out of state or no phone)
  • Have advanced COPD or CHF
  • Have history of open abdomen or extensive lysis of adhesions for bowel obstruction
  • Ascites due to cirrhosis or malignancy
  • Active infection such as infected mesh
  • Ventral hernia greater than 12 cm in size



Those interested may participate in this study at UT Health – Memorial Hermann in Houston, Texas 77024, or at UT Health – Lyndon B. Johnson (LBJ) Hospital in Houston, Texas 77026. Feel free to contact Angielyn Rivera, of UT Health – Memorial Hermann at 713-486-1350 or at with any questions or concerns. Debbie F Lew, MPH, CCRC, of UT Health – Lyndon B. Johnson (LBJ) Hospital, is also available for contact at 713-566-5097 or at



This clinical trial is sponsored by the University of Texas Health Science Center, Houston. Shinil Shah, DO, of UT Health – Memorial Hermann, and Mike K. Liang, of UT Health – Lyndon B. Johnson (LBJ) Hospital, are the Principal Investigators.
