JACKSONVILLE, FLA. – Super-obese patients who have laparoscopic repair for ventral hernias have complications at a rate more than twice that for overweight individuals undergoing the same operation, according to an analysis of 10-year data presented at the Association for Academic Surgery/Society of University Surgeons Academic Surgical Congress.
“Patients with a body mass index of 40 kg/m2 or greater were found to be significantly more likely to have a complication following laparoscopic ventral hernia repair,” said Robert A. Swendiman, MD, of the University of Pennsylvania, Philadelphia.
Dr. Swendiman and his colleagues analyzed outcomes of 57,957 patients in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database who had laparoscopic ventral hernia repair (VHR) from 2005 to 2015. The dataset was stratified into seven different BMI classes, and by hernia type (reducible or strangulated) and time of repair (initial or recurrent).
The overall complication rate for the study population was 4%, ranging from 3% in overweight patients (BMI of 25-29.99 kg/m2) to 6.9% for the super obese (BMI of 50 kg/m2 or greater); 61.4% of the study population was obese. “Initial repair and reducible hernias had lower complication rates than recurrent and incarcerated/strangulated hernias,” Dr. Swendiman said. The study considered 1 of 19 different complications within 30 days of the operation.
Three weight groups had the highest odds ratios (OR) for complications: underweight patients (less than 18.5 kg/m2, OR 1.46, P = .283); morbidly obese (40-50 kg/m2, OR 1.28, P = .014); and super obese (greater than or equal to 50 kg/m2, OR 1.76, P = less than .0001). However, Dr. Swendiman noted, “Overweight patients had a lower rate of overall complications compared to normal-weight individuals.”
These findings were consistent with a prior analysis the group did that found patients with BMI greater than 30 kg/m2 was associated with increased risk of complications after open VHR, Dr. Swendiman noted (Surgery. 2017;162[6]:1320-9).
“Future studies should be considered to evaluate the role of weight reduction prior to hernia repair as a method to reduce patient risk,” Dr. Swendiman said. Laparoscopic repair may be preferable to open VHR in obese patients, depending on the clinical context, he said.
Dr. Swendiman and coauthors reported having no financial disclosures.
